ปั๊มจุ่ม How to maintain a submersible pump for long-lasting use Submersible pumps : To ensure a long-lasting pump, in addition to selecting quality products that meet the required standards for the application, another important factor is "maintenance." This article will help you prolong the life of your submersible pump. Submersible pumps , or "divo" pumps, are submersible pumps that are submerged in water. Their primary function is to pump water from one source to another. They can be divided into two types based on their use: clean water and wastewater. Specifically, submersible pumps, in order to ensure a long-lasting pump, are not only designed to be high-quality and meet the required standards for the application, but also to ensure "maintenance." This article will help you prolong the life of your submersible pumps. Wastewater treatment products can accumulate dirt and debris, which can negatively impact the pump's internal systems. Failure to maintain these components can also pose a risk. Therefore, it's important to know how to properly maintain your submersible pump. How to maintain Submersible pump for clean water 1. When connecting the pump, ensure proper electrical tape is applied to prevent water from entering the wires. Poor electrical tape can cause water to enter the pump, damaging the pump and potentially harming the user or installer. 2. Be careful of the rubber parts around the wire terminals. When the pump is submerged in water for extended periods, the rubber may deteriorate, allowing water to enter the pump. Therefore, use silicone or sealant to seal the rubber around the wire terminals. 3. Be careful not to let debris or other debris get into the pump. This can cause debris to become trapped in the impeller, slowing down its rotation speed. A fine screen should be installed to prevent debris from entering the pump. 4. Do not connect the wires longer than 10 meters, as a voltage drop will slow the pump's operation and damage the motor. Submersible pumps for wastewater 1. Check the voltage and current to ensure they meet the specifications on the product nameplate. Do not exceed or exceed the specified voltage by more than 10%. Also, check the water flow path for normal operation. 2. If you have an electrical insulation meter, perform monthly measurements. If the insulation resistance is below 1 MΩ, the motor should be replaced. 3. Every 6 months, change the lubricating oil and replace the mechanical seal, as the rubber is constantly exposed to water pressure. 4. Every 2-5 years, the pump should be lifted and inspected regularly for dirt or debris to prolong its life. "When performing maintenance on submersible pumps, always disconnect the power supply.This could be dangerous to the operator."

"Choosing the use point of a water pump from Curve to achieve maximum efficiency and save energy" Selecting the water pump usage point from Curve Installation affects performance and energy consumption. Overdesigned, requiring a bypass valve. Old, inefficient water pump. Improper layout, very small, long pipes, etc. Selecting the right pump for efficient use, energy saving, and extended life of the water pump. 1. Select a pump with a duty point within the maximum efficiency range (BEP). 2. If water usage (load profile) varies significantly, consider a variable speed pump system or a booster pump. 3. Select the appropriate pipe size (flow velocity 1.5-2.5 m/s). 4. Avoid creating air pockets in the suction pipe. 5. Keep suction pipe connections as short as possible with minimal joints. 6. Avoid excessive elbows, reducers, or other fittings. 7. Do not operate the pump far to the right of the BEP, as this will significantly increase the flow rate and NPSH, increasing the risk of cavitation. ** NPSHr (Net Positive Suction Head Required) is the suction performance of the pump, it shows the pressure required to be brought in by the pump at a given flow to avoid cavitation in the liquid. 8. Do not operate the pump too close to the shutoff head. This will result in very low flow rates, which can cause water temperature and pressure to rise, which can be dangerous. This also leads to a lower efficiency level for the pump. 9. The motor should be operated at 60-100% of full rated capacity for maximum efficiency. 10. Operating the pump at less than 50% capacity will significantly reduce motor efficiency. 11. One-third of motors in actual use are oversized and operate at less than 50% of full rated capacity. 12. Operating a pump with a larger motor than required not only lowers efficiency, but also costs more than it should. Furthermore, it also reduces the power factor, leading to higher electricity bills.

5 Things to Know Before Choosing a Submersible Pump 1. Well Mouth Size 2. Well Depth 3. The water level in the well is visible from the well mouth. 4. The amount of water in the well. 5. How far is the water delivered? --------------------------------------------------------------------------------------------------------------------------- Let's take a detailed look at each point for how to choose a deep well pump. 1. Size of the well mouth LEO submersible pump : 4XR, 4LPS, 4LPY (4-inch well) / 3XR, 3LPS, 3LPY (3-inch well) 2. The depth of the drilled well Most artesian wells in the Northeast are not drilled very deep, and water is obtained relatively quickly, for example, at 30-40 meters. 3. How many meters from the mouth of the well is the water level that has risen?                  When we look down from the mouth of the well, we can usually see the water level rising up because there is pressure in the well. We measure the water level from the mouth of the well to the rising water level to see how deep it is. Most often, we will find it at 10, 15, or 20 meters. Formular Water level from well mouth + pumping distance (We usually allow a pumping depth of 20 meters or more.) **Note Do not lower the pump until it touches the bottom of the well, as the impeller may get stuck in the mud and cause damage. Allow space for the pump. It must be at least 5 meters above the bottom of the well.     “Suppose we have a well that is 40 meters deep, the water level at the mouth of the well is 15 meters, and the pumping distance is 20 meters. That's 15 + 20 = 35 meters, so we should lower the pump to a depth of 35 meters.”   ** NOTE 1. Allow for a pumping distance of 15-20 meters or more if drilling a very deep well, such as 100 meters. We can increase the pumping distance to 30-40 meters. 2. Do not lower the pump until it touches the bottom of the well, as the impeller may get stuck in the mud and cause damage. Allow for a pump clearance of at least 5 meters above the bottom of the well.   "A well is 100 meters deep. How deep should the pump be?" The water level at the well mouth is 30 meters, and the pumping distance is 30 meters (with an extra 30 meters because the drilling is very deep). Therefore, 30 + 30 = 60 meters. We should lower the pump to a depth of 60 meters. 4. Water volume in the well (liters/hour)? You can inquire directly with a well driller. In the Isaan region, it's typically 4-8 liters per hour. You can also check it yourself via the app: BADAN4THAI2. "Badan4Thai" is now available today!! Play Stored :  https://play.google.com/store/apps/details ... App Stored :  https://apps.apple.com/th/app/badan4thai2/id6444678587?l=th 5. How many meters is the water delivery distance? Head calculation Head 10 meters horizontal = Head 1 meter vertical Therefore, 200 / 10 = 20 meters.   Example Drilling a well 40 meters deep, the water level can be seen from the well mouth at 15 meters, sending water 200 meters horizontally into the garden. What head pump should be selected? Water level at the well mouth: 15 meters + pumping distance: 20 meters = pump depth: 35 meters. Horizontal delivery distance: 200 meters = Head: 20 meters. Therefore, the total delivery distance is 35 + 20 = 55 meters (a pump with a Head of 55 meters or more should be used).

The "HVAC" system , also known as the air conditioning system, is a heating, cooling, and ventilation system that is larger than a typical home air conditioner, giving it the potential to transfer air to improve air quality. It is therefore suitable for office buildings, department stores, houses of two stories or more, as well as warehouses and industrial plants that require temperature and humidity control for production. Now, let's take a look at what an HVAC system is and how it works. What is HVAC? HVAC system is an air conditioning system that manages air to control temperature, humidity, cleanliness, and distribution as required for a given space. It consists of H-heating, V-Ventilation, and AC-Air conditioning. The HVAC system consists of three main components: 1. Heat : Piping systems for heat-conducting fluids or ducts, if it's a forced air system. 2. Ventilation : Either natural or forced. Forced ventilation is most commonly used for air purification. 3. Air conditioning : This is the process of removing heat from the interior of the building. The HVAC system's structure is that all three systems work together at all times to ensure efficient air management. Therefore, it is suitable for industrial locations with complex closed systems or locations that require temperature and humidity control. What is the function of an HVAC system? What is it like? Appropriate control of the climate in a room depends on the type of room use. However, in general, the temperature and humidity that create a comfortable feeling, or Thermal comfort, are controlled at 22-25 degrees Celsius, with relative humidity controlled at 30-60% RH and an air ventilation rate of approximately 20% of the total amount of circulating air. Other uses are determined according to the standards of each type of room as follows: 1. Temperature control The system controls temperature by using a coil panel as a connector between the refrigerant and the air. This allows the air inside and outside to exchange only heat. The cooling coil draws heat from the air inside the room and the hot coil dissipates heat from the refrigerant, which absorbs heat from the air inside the room, to the outside. The outside air dissipates heat from the hot coil. Depending on the usage pattern, each room will have a different optimum temperature. Therefore, we divide it as follows: Room temperatures for humans generally range from 20 to 26 degrees Celsius, according to ASHRAE Standard 55-1992. This range depends on the type of room used and the user's preferences. Room temperatures for animals vary, and the body temperature of each animal is typically designed to be between 18 and 26 degrees Celsius. Room temperatures for plants: The type of plant determines the temperature used. Designs can range from temperate to tropical plants, and optimum humidity is often considered. The design temperature range can range from 18 to 40 degrees Celsius. Room temperatures for chemicals or equipment used to store chemicals, including some types of equipment, require an appropriate temperature range to prevent chemical reactions and minimize damage to electronic components. 2. Humidity control Normally, in reducing the temperature, the cooling coil panel will function to reduce the temperature of the air and reduce the humidity in the air at the same time. When the air hits the cooling coil at the condensing temperature, the humidity in the air will condense into water droplets. However, for the cooling coil panel, the efficiency in reducing the temperature will be greater than reducing the humidity in the air. Therefore, the temperature must reach a predetermined point before the humidity drops to the predetermined point. Therefore, in reducing the humidity in the air, the cooling coil panel that is still working will cause the room temperature to decrease continuously. And there must be a device to increase the heat to raise the air temperature to be equal to the predetermined point. There are many systems for increasing heat, but the most popular system currently used is the installation of an electric heater. This system can immediately add heat to the system and is easy to control, but in exchange for increased heating energy.   3. Air circulation Air circulation is extremely important. If air is not distributed evenly, it will create dead corners, which will result in a lack of air circulation in that area, causing the accumulation of carbon dioxide and various germs, causing people in that area to feel uncomfortable, stuffy, or even infected by germs. Research has shown that the appropriate air circulation in a room used for various activities is calculated by the air circulation rate in units of room volume per hour (Air Chang per Hour, ACH). General air circulation systems are designed based on the ratio of indoor air to outdoor air. They are divided into 2 systems: Single-Pass Air : This system does not recirculate indoor air. Instead, all outdoor air is taken through the air conditioning system and used to condition the room. The entire room is then exhausted. Recirculation Air : Because air conditioning requires energy to reduce temperature and humidity, the larger the room, the more energy is consumed. Recirculation involves taking approximately 80% of the pre-conditioned and humidified indoor air, mixing it with approximately 20% of the outside air, and then re-entering the system.   4. Air pressure in the room To control contamination between the interior and exterior, there must be a difference in air pressure. Air is a collapsible fluid, typically flowing from high pressure to low pressure. Based on this principle, contamination prevention can be divided into two types: Negative Pressure Rooms: These rooms have lower air pressure than the surrounding room or environment. These rooms are used to control the spread of pathogens to the outside environment, such as isolation rooms for airborne infectious diseases, laboratory equipment, etc. Positive Pressure Rooms: These rooms have higher air pressure than the surrounding room or environment. These rooms are used to prevent external pathogens from mixing with the air inside the room, such as dust-free parts production rooms, operating rooms, and sterile rooms for infectious-prone patients. 5. Air filtration The air is mixed with dust and various particles, which are the root cause of many causes of harm to humans, manufacturing processes and research errors, especially the spread of germs. In order to separate these foreign objects, it is necessary to have an air filtration system that is efficient and consistent with the standard air flow rate of each type of room. The standards that are accepted worldwide are: The pre-filter is the first filtering stage, reducing large dust particles, increasing efficiency and extending the life of the next, finer filter. The medium filter is the final stage, filtering up to approximately 95% of dust particles. The HEPA filter is the final stage, before the air is delivered to the room, filtering up to approximately 99% of dust particles as small as 0.3 microns. HVAC System The difference between HVAC and air conditioning HVAC vs. Air Conditioning: Air conditioners are the final part of HVAC, but they are often used interchangeably. When referring to all types of heating or cooling equipment in a home, HVAC is considered an umbrella term, while air conditioners are only one part of the system. HVAC System Lifespan: The lifespan of an HVAC system depends on how long the equipment lasts and whether it is regularly maintained or serviced. If the operator or user follows maintenance recommendations, the equipment will function efficiently for many years. Choosing the right air conditioning system for your application can significantly save energy, especially in large office buildings, shopping malls, and factories where temperature control is essential. HVAC systems are ideal for maintaining a constant indoor temperature and removing moisture, which can lead to problems down the road.

Nowadays, most industrial plants use steam boilers. Let's take a look at the types and types of steam boilers these plants have and why most plants need to have steam boilers.   Boiler Whai is boiler ?                 What is a boiler? A boiler is a steam generator. These steam generators combust fuel in a boiler, generating steam and pressure. This pressure is then transferred to various machines within the industrial plant. The size of a boiler depends on the amount of energy and pressure the machines require. Boilers in industrial plants are called steam generators. These steam generators are enclosed, 2 liter capacity, and maintain a pressure greater than 1.5 times atmospheric. They convert water inside the boiler into steam. Steam generators are essential for powering various machinery, whether large or small. In factories and industrial operations, steam generators are commonly used to generate energy. For very large boilers, gas is often used as fuel to generate steam energy. Most boilers are primarily made from carbon steel. Their structures must be designed according to engineering principles and international standards. The steam produced is used in various industries, such as: Used for electricity generation (Electricity Power) Used for mechanical power generation (Mechanical power from steam turbines) Used for drying in the drying industry (Dry-out) Used as heat in various sterilization or pasteurization processes As we can see, boilers are widely used in all industries, from petrochemicals to buildings and hospitals. These boilers require proper engineering design and standards, and the operators must be certified and inspected by qualified engineers. Types of boilers     There are many different types of boilers, but generally there are two main types: fire tube boilers and water tube boilers. The rest may be hybrid boilers, which are a combination of fire tubes and water tubes. Both types of boilers, fire tube and water tube, have their own advantages and disadvantages, depending on their suitability for use in that particular industry. 1. Fire Tube Boiler Fire Tube Boiler A fire tube boiler is a boiler with fire in the tubes and water outside. This type of boiler has a combustion chamber, and the fire is passed through the fire tubes. Heat is exchanged from the fire to the tubes, and then from the tubes to the water. Fire tube designs include single-flow, double-flow, triple-flow, and quadruple-flow. Generally, fire tube boilers have a pressure of no more than 150 psi and a capacity of less than 15 tons per hour. Fire tube boilers are suitable for use in railway locomotives, steamships, rice mills, paper mills, animal feed mills, and canned fruit factories. Fire Tube Boiler Advantages of firetube boilers Large water volumes provide relatively stable steam delivery. Cheap. Does not require high-quality water. Disadvantages of fire tube boilers The furnace takes a long time to ignite. Low heat transfer efficiency. Due to the high heat energy stored in the water, a malfunction, such as an explosion, is extremely dangerous. Unable to produce high-pressure, high-volume steam. 2. Water Tube Boiler Most large boilers we often see are water-tube boilers. This type of boiler has water in the tubes, and a fire outside. The principle behind its operation is that the furnace has a fire outside. The fire transfers heat to the tubes, and the tubes transfer heat to the water inside. Water Tube Boiler This type of boiler can produce pressures exceeding 150 psi and has a very high production capacity. This type of boiler is mostly used in steam turbines, sugar factories, oil refineries, petrochemical plants, or marine vessels. There are many different designs of water tube boilers, depending on the type of heat used, such as the conventional water tube type, WHBT furnace, HRSG furnace, biomass furnace, and nuclear reactor. Advantages of Water-Tube Boilers Good water circulation system High heat transfer efficiency Short ignition time High pressure production High steam production rate Safer than fire-tube boilers in the event of an explosion, such as a malfunction, due to the low energy storage capacity due to multiple pipes   Disadvantages of Water-Tube Boilers High price High maintenance costs If usage is inconsistent, the steam will also become unstable. The water used must be of high quality, as scale can form. General boiler equipment    Boilers require control devices to ensure efficient operation and safe operation. Let's learn about these devices and safety systems. The Safety Valve (PSV) acts as a safety valve that releases pressure from the boiler if the pressure exceeds the designed limit. It must be designed to match the pressure and discharge volume, making it a crucial component for safety. The Main Steam Valve is used to turn on and off the steam generated from production for use in various parts of the plant. The Blow Down Steam Valve is a bottom drain valve that removes scale from the boiler, ensuring efficient operation. The Feed Water Pump is a high-pressure water pump that feeds water into the boiler. Most commonly, a multistage pump is used. Centrifugal Multistage Pump Vertical Multistage Pump 5. Water Level Gauge/Control : Used to monitor the water level in the boiler and to control the boiler's water level. 6. Pressure Gauge : Used to monitor boiler pressure. 7. Pressure Switch : Used to control the pressure inside the boiler. 8. Burner : The burner creates a flame generated by the interaction between the fuel and air, which transfers heat to the water. 9. Insulation : Used to prevent heat leakage from the boiler, minimizing loss and preventing hazards during operation. The use of boilers or steam generators is widely popular in factories and various industrial enterprises, as it saves energy and is environmentally friendly. However, it is crucial for users to be skilled, experienced, and knowledgeable in the use of the equipment to avoid problems and accidents.

Reverse Osmosis is a system that removes contaminants from water by using pressure from a water pump to push it into a special membrane with very small pores (0.0001) microns to block various contaminants from passing through, such as viruses, lead, arsenic, pesticides, chemical fertilizers. It can remove chemicals, heavy metals, and various germs in water up to 95%. What is Reverse Osmosis (RO)? RO systems are widely recognized as the most effective water filtration method and are certified by the Environmental Protection Agency (EPA) to effectively remove contaminants and toxins, resulting in cleaner, more flavorful water. กรองน้ำระบบ RO Working principle of Reverse Osmosis (RO) Before water reaches the RO filter, it must first pass through a pre-filter. This filter removes sediment and chlorine to prevent these impurities from clogging or damaging the RO filter. Ideally, it's best to have three pre-filters: a PP filter, a carbon filter, and a resin filter. Once the water passes through these three layers, it's pressurized by a pump, forcing it into the RO filter. After passing through the RO filter, the post-carbon filter removes color, odor, and chlorine, and improves the taste of the water. The filtration process for each stage is as follows: 1. PP Sediment Filter : Filters out small contaminants in the water, such as dust, sediment, and suspended solids. This is the first stage of water filtration. 2. Pre-Carbon Filter/Block Carbon Filter : Filters out chlorine, odor, color, sulfur, organic matter, and other impurities. This is the second stage of water filtration. Without the first two stages, the RO filter will clog very quickly. 3. Resin Filter/Ion Exchange Filter : Captures limescale and removes water hardness. This is the third stage of water filtration. Without this stage, the water will become hard. Drinking it won't leave you with a smooth throat. 4. RO Membrane Filter : Filters Total Dissolved Solids (TDS) to make the water free of germs, viruses, dirt, and chemicals, such as arsenic, lead, and bacteria. This ensures that the water passing through the RO system is of the highest purity, as other systems cannot filter down to the level of viruses. 5. Post Carbon Filter : Removes odors, colors, chemical contaminants, and radioactive substances, as well as improving the taste of the water to natural and pleasant to drink.   RO Filter   Water from the RO system is divided into 2 parts. After the water has gone through every step of filtration, the water will be stored in a pressure tank to reserve water until the tank is full. The RO system will then shut down. When we turn on the faucet, water will flow from the tank to the faucet. RO systems divide water into two parts: Buffer water – This is filtered water for drinking, making up approximately 30-40%. Waste water – This water contains residual contaminants. This water flows into a separate drainpipe. Therefore, a flow restrictor is required to limit the amount of wastewater to conserve water.   Why do we need a pressure tank ? The RO pressure tank is like a reserve water tank for the RO system because the water production of the RO system releases water slowly, taking a much longer time than other systems. If water is used continuously without any reserves, we will not be able to use water continuously. But if there is a pressure tank, we will be able to use water continuously without having to wait. But it also depends on the volume of the pressure tank as to how many liters it is. Pressure Tank Should we drink water from a reverse osmosis system? Although water obtained from a Reverse Osmosis (RO) system removes beneficial minerals such as calcium and magnesium from the water, it does not make RO water harmful to us. We drink water to hydrate our body and lubricate our joints, as our body is made up of 70-80% water. So, should we drink water from an RO system? It depends on our own needs. There is nothing to worry about.   "Lifespan of RO water filter" Each type of water filter has a different lifespan. For example, PP Sediment water filters, Pre-Carbon water filters, Resin water filters, and Post Carbon water filters all have a lifespan of approximately 6-8 months, depending on the water quality in each area. However, RO water filters have a lifespan of approximately 1 year. "Advantages of Reverse Osmosis System" This is the cleanest filtration system, filtering water down to 0.0001 microns. It's popular in various industries, including commercial bottled water, pharmaceuticals, food and beverage manufacturing, and any industry requiring exceptional water cleanliness. Whether it's tap water, groundwater, brackish water, or any other water, RO water can be consumed immediately. Introducing an RO water filtration system ensures that products and services are of high quality, clean, and safe for consumers, enhancing your business image and credibility. Removing Total Dissolved Solids (TDS) to zero, including: - Toxic and harmful chemicals - Foul-smelling chlorine - Heavy metals, residues, contaminants, and toxins - Germs, bacteria, dust, powder, and particulate matter - Minerals such as calcium, magnesium, and other substances invisible to the naked eye า        For all these reasons, the water tastes good, has no bad odor, is suitable for drinking and used in various industries that use water in production, such as medicine, food and beverages, and ice. Importantly, whether our water source is tap water, groundwater, or brackish water, this system can filter it all. It is a filter system that is reliable and most accepted because it is clean, safe, and delicious, making it widely popular and has a variety of uses.   >> Content : starting a drinking water business << Click For more information Tel. 02-292-1067-70 Youtube : Leopump ประเทศไทย Line Official : @775ruust Facebook : LEOpumpThailand   TikTok : Leopumpthailand

Cavitation We'll learn about cavitation. What is cavitation and why is it important? Cavitation is a phenomenon that often causes damage to equipment such as water pumps , control valves, and other devices that handle fluids, pressure, and temperature. The damage will appear as if a needle has punctured the bottom. This cavitation effect or air pockets can penetrate the metal or steel. Cavitation Damage What is cavitation ?  There are 2 main types of cavitation: 1. When the temperature of the liquid increases 2. When the pressure decreases (pressure reduction, which is similar to the surface pressure of the flowing liquid, prevents it from vaporizing. There are several ways to reduce pressure, including using a vacuum pump).   Cavitation Cavitation is the formation of air pockets in a liquid. It occurs when the pressure in a liquid at a constant temperature drops below the boiling point of steam, resulting in vaporization. The vaporized liquid then re-liquidates. The damage is caused by a phenomenon known as a "single cavitation bubble." This is when a liquid droplet, approximately 3.3 mm in diameter, collapses, and then partially transforms into a gaseous liquid. Shear flow occurs, sucking gas into the surface, creating a microjet that penetrates and damages the workpiece, resulting in pitting. Cavitation In the case of a water pump, for example, if the suction pressure is insufficient to meet the pump's requirements, cavitation can also occur. Pump Cavitation If we observe the pump's inlet direction, we'll notice that the liquid pressure at the suction end of the pump will decrease. If the suction pressure is less than the vapor pressure, the liquid will change to a gas. As the liquid continues to flow into the pump, the pump will build up pressure, and the gas-based liquid will return to a liquid state. This creates a cavitation effect that destroys the internal components of the pump, creating pores. Pump Cavitation Therefore, to prevent cavitation in this case, the pump inlet pressure must be monitored to ensure it is at least within the required specifications. It 's not just pumps that can suffer from cavitation effects. A common problem is valves. When the valve is severely closed, the liquid passing through the valve increases in velocity. As the liquid passes at high speed, the pressure decreases, causing a change in state from liquid to vapor. As the velocity decreases, the pressure increases, and the liquid returns to liquid, causing cavitation effects and damage to the valve interior.

Some people may be wondering what type of pump to use for the area they need to pump water, given the size of their pond. This is especially true for pumping or drawing water from relatively deep ponds. These pumps are intended for small-scale irrigation or sprinkler applications, agricultural, industrial, and household water supply. So, let's take a look at which type of pump to use: Jet pumps vs. submersible pumps. Which is better? We'll compare pumps that can pump water from similarly deep wells. Submersible pumps and jet pumps have distinct advantages, including: Jet Pump Single Jet pump Double - Jet pump Available in both double-jet and single-jet pumps. Suitable for small ponds up to 2 inches. Adds additional pressure to the water circulation. Often comes with a control unit, making it convenient and easy to use. The pumps are installed on land, making them easy to maintain. Maximum suction depth is approximately 30-45 meters. The installation process is more complicated than that of a submersible pump. Submersible Pump Submersible pump Available with both regular household electricity and solar power. Available in a wider range of models and sizes than jet pumps. Suitable for ponds 3 inches and larger, and a wider range of sizes. Installation is relatively simple and straightforward. High water delivery capacity. Maintenance requires pulling the pump out of the pond. Conclusion Jet pump vs. Submersible pump Water level: If the water level is at the ground surface level not exceeding 9 meters, a jet pump will be more suitable. However, if the water level is between 9 and 30 meters deep, a deep well pump should be chosen because it can send higher and farther than a jet pump.   JET PUMP Injection pump, working principle of injection pump (Jet Pump) Water from the nozzle, which is under high pressure, will rush through a narrow channel of the pipe that has a neck shape (Venturi) and with the speed that rushes out of the nozzle, causing the surrounding water to flow along the water line through the neck shape pipe as well and flow into the suction line of another pump, such as a pipe pump or a centrifugal pump. Some of the water volume leaving the pump will be sent back into the new nozzle, while the rest will flow out for use.

Axial Flow Pump Axial flow pumps or shaft pumps are a type of pump that is designed to allow fluid to flow along the axis of a rotating shaft, unlike centrifugal pumps where fluid is thrown radially. Basic Operating Principles Rotating Impeller: The pump contains multiple impeller blades arranged along its axis. As the impeller rotates, it propels the fluid in front of it, pushing it forward in the axial direction. Driving Force: The force that causes the fluid to move is the individual impeller blades, each designed to be angled to push the fluid forward. As the impeller rotates, the fluid is continually pushed forward, creating a flow of fluid. Flow: As multiple impeller blades work together, the fluid is accelerated and continues to flow through the pipe. Axial Flow Pump High Flow Rate: This type of pump is ideal for applications requiring high flow rates, such as drainage, cooling, and irrigation systems. Low Pressure: Despite its high flow rate, axial flow pumps typically do not provide very high pressures, making them ideal for applications requiring fluid delivery over short distances. Simple Structure: This type of pump has a relatively simple design, resulting in low production and maintenance costs. Axial Flow Structure Applications Axial flow pumps are widely used in a variety of industries, including: Water industry: Used for pumping raw water from natural sources, wastewater, or wastewater treatment systems. Agricultural industry: Used for pumping water for irrigation. Paper industry: Used for pumping water during the paper production process. Energy industry: Used in cooling systems in power plants. Conclusion Axial flow pumps are pumps that work by pushing fluid forward along the axis of a rotating shaft. With the advantages of high flow rates and simple construction, this type of pump is popular in many industries. Axial Flow Pump Advantages Ideal for applications requiring the movement of large volumes of liquid at low pressure, such as drainage and irrigation systems.

What is a diaphragm pressure tank? Why is it important? A pressure tank is a tank used to store water that is left over from pumping by a water pump and from the flow of water at the water supply point. It is stored in the tank and then distributed to the pump. It is commonly used in buildings, condominiums, industrial factories, houses, etc.   Structure A diaphragm pressure tank is a closed vessel containing a diaphragm (a flexible rubber sheet) inside. It is divided into two parts: 1. The water-filled part , which is connected to the water supply pipe. 2. The air-filled part , which is located above the diaphragm.   Pressure Tank Operation Principle The principle of operation is that when the water pump is turned on, it first pumps water into a storage tank, which contains a diaphragm inside the tank. The bag expands until the bag is full, then shuts off. When water is used, water is first drained from the pressure tank before the pump has started. For example, in homes and buildings with conventional water pumps without pressure tanks, the pump starts immediately upon turning on the water. This can cause loud noises due to the pressure in the pipes, creating a reaction known as water hammer. However, if a pressure tank is used and the water is turned on, the pump will not start, but will use the water in the tank first, until the pressure drops, and then the pump will resume pumping water to refill the tank. Why is a diaphragm pressure tank important? 1. Maintains constant water pressure: When water is turned on, the water in the pressure tank is used first, preventing rapid water pressure drop and preventing the pump from running too frequently, which extends the life of the pump. 2. Prevents water hammer: When the pump suddenly stops, the water flow in the pipes also stops. This can cause shock or pressure surges in the pipes, which can damage pipes and equipment. A diaphragm tank helps absorb these shocks. 3. Reduces pump load: Because the diaphragm tank stores reserve water, the pump reduces the need for frequent operation, saving energy. 4. Prevents pump run-off: Without a diaphragm tank, the pump could run until the water in the system is depleted, causing the pump to run dry and become damaged.   For water pumps without a pressure tank: During a water pump shutdown due to the required pressure, if water is used, the system pressure will gradually decrease until it reaches the point where the pump must restart. This may result in continuous operation or frequent disconnection, reducing the pump's lifespan. When a water pump stops, if water is used, the system pressure will gradually decrease until it reaches the point where the pump must restart. During this time, the system pressure will become unstable, resulting in inconsistent pressure. The water supply may be inconsistent or weak. Therefore, when large amounts of water are used, such as in high-rise buildings, a pressure tank is required. Bootster Pumps can address pump lifespan and inconsistent water pressure.   Mini Booster Diaphragm Pressure Tank                         Pressure Tank Components Pressure Tank The tank is available in both vertical and horizontal configurations, with a diaphragm insert inside. Diaphragm Inser t This is the insert used to hold water inside the diaphragm pressure tank. It is typically black and made from a variety of materials, such as Butyl, which is suitable for potable water and is of high quality, EPDM, a highly flexible synthetic rubber, or natural rubber. Air Pressure Air is located between the tank and the diaphragm insert. Pressure Gauge (available on some models) A device used to measure the pressure inside the tank.     How to Select You need to know the water pressure you're using to adjust the pressure appropriately for your application. Choose the right size for both the water pump and the pressure tank. Choose quality materials. Precautions for Use Check the pressure tank's pressure regularly every month.

A swimming pool pump is the heart of every swimming pool. Its primary function is to draw water from the pool through the skimmer and main drain pipe, push water through the outlet filter, and return it to the pool via the return pipe. The filter traps hair and lint. The electric motor is air-cooled and should not be allowed to splash into the motor, as this can cause damage. Choosing the right swimming pool pump is crucial to ensuring the pool's filtration system operates efficiently. This not only keeps the pool water clean, but it also reduces long-term costs, such as electricity and maintenance. An improperly sized swimming pool pump can lead to various problems, such as unclean water, dirt buildup, high electricity bills, and accelerated equipment wear. Therefore, selecting the right swimming pool pump is crucial.   What is a swimming pool pump? How is it calculated? For pools with waterfalls, fountains, or water jet systems, you may need to add approximately 5-10% of the total water volume to the pool pump to efficiently handle the additional water flow. This calculation can be done using various formulas based on the shape of the pool: Rectangular pool: Width x Length x Depth x 7.5 = Volume (gallons) Circular pool: Diameter of pool ÷ 2 to obtain the pool radius. Then, use the formula 3.14 x Radius divided by 2 x Depth x 7.5 = Volume (gallons). Calculating the flow rate of a swimming pool pump (Flow Rate) The flow rate of a swimming pool pump refers to the amount of water a pool pump can pump in a given period of time. Generally, we should expect the pool pump to circulate the entire pool in 8 hours to maintain cleanliness and balance. We can calculate the required flow rate using the formula: Example: A swimming pool with a volume of 75,000 liters and requiring a circulation cycle in 8 hours. If faster water filtration is required, such as for a pool with a large number of users, a shorter circulation cycle time, such as 6 hours, may be considered for more efficient water filtration. Choosing an oversized pool pump can waste energy and increase costs. Therefore, choosing the right pool pump will save energy and reduce costs in the long run. You should also consider additional circulation for accessories such as waterfalls or water jets, which require approximately 10-15% more flow than calculated to ensure the overall system operates smoothly and efficiently. The flow rate is the total volume of water a pool pump can circulate in a given period of time. For example, a system should circulate the entire pool in 8 hours, which is a common standard.   Calculation Formula Flow Rate (liters/hour) = Pool Water Volume (liters) ÷ Circulation Time (hours) Flow Rate (liters/hour) = Pool Water Volume (liters) ÷ Circulation Time (hours) Flow Rate (liters/hour) = Pool Water Volume (liters) ÷ Circulation Time (hours) Calculation Steps Q = Flow Rate (liters/hour or cubic meters/hour) V = Pool Volume (liters or cubic meters) T = Circulation Time (hours) Calculate Pool Volume (V) V = Length x Width x Average Depth. If volume is expressed in cubic meters, multiply by 1,000 to convert to liters (1 cubic meter = 1,000 liters). Determine the Circulation Time (T) Typical swimming pool circulation time: Regular swimming pools: 6-8 hours Kids' pools: 2-4 hours Hotel/public pools: 4-6 hours Calculate the Flow Rate (Q) Dividing the pool volume (V) by the circulation time (T).   Consideration of other factors Criteria In addition to flow rate, other factors must be considered to ensure optimal pool system efficiency. Pipe Friction : If your pool has long or curved pipes, this creates resistance to water flow. You may need to choose a more powerful pool pump or use a larger pipe to reduce friction. Filter Type : Different filter types, such as sand, ceramic, or paper, have different water pressure requirements. Sand filters typically require higher pressures, while ceramic filters offer the advantage of finer filtration but require more maintenance. Pump Distance from Pool : Distance affects pool pump efficiency. If the pump is located far from the pool, you may need to increase the pump's power or use a friction-reducing pipe to compensate for pressure loss. Climate and Environment : If your pool is located in an area with high winds, dust, or trees, you should choose a pool pump capable of circulating the water more frequently to maintain clean water. Additional filtration equipment may also be required to prevent leaves or dust from entering the system. Water Temperature : If your pool is heated or heated, water viscosity and flow may affect the pool's performance. You may need to choose a pool pump that can handle higher liquid temperatures. Additional Applications : If your pool has additional features, such as a waterfall, fountain, or spa system, you may need to add a pump or select a pump that can handle these increased flows to ensure optimal performance. Sand or cartridge filter Sand Tank Filter types can include diatomaceous earth (DE) filters, sand filters, or cartridge filters. DE filters are the most expensive, but they also produce the cleanest pool water. Cartridge filters are easy to maintain. If you clean them every four to six months, they will last for two to four years. Sand filters are the least expensive, but they don't filter water as well as DE and other types of filters.     Proper Swimming Pool Pump Installation The water pump should be installed within the pool area or as close to the pool as possible and placed in a suitable location. It should also be secure and stable to ensure user safety. The diameter of the water pipe used should be larger than or equal to the pump outlet pipe. If possible, use a suction pipe with a diameter no smaller than 2 inches. The overflow channel should be 20 cm deep. The calculation of water reserve area in the case where the pool is full of users is as follows: Each person uses 1 square meter of space. Each person displaces approximately 75 liters of water. 75 x number of people in the pool = reserve water volume. A private pool uses 2 square meters of space per person, which will displace approximately 75 liters of water. Calculate 75 x number of people in the pool using the formula (pool size (sq m) ÷ 2) = reserve water volume.
