cooling tower pump which is used for evaporative condenser

The cooling tower pump is responsible for transporting water from the collecting tank to the condenser shower pipe, and evenly spraying the water on the surface of the condensate discharge pipe through nozzles, utilizing the evaporation of water to carry away the heat, thus effectively lowering the temperature of the refrigerant. This pump is usually characterized by high efficiency, durability and stable performance and is widely used in cooling towers, air conditioners and industrial cooling systems.

cooling tower pump features:

1. Excellent hydraulic design: the pump impeller adopts a well-designed hydraulic model with excellent static and dynamic balance. This design ensures that the pump exhibits stable performance during operation, reduces vibration and noise, and improves usage efficiency. In addition, the impeller’s efficient hydraulic design allows the pump to better adapt to different working conditions during operation, ensuring efficient liquid transportation.
2. Extended pump shaft: the pump shaft adopts the design of motor extended shaft, which makes the pump can be directly connected to the motor, reducing the complexity of the intermediate transmission device, thus improving the overall working efficiency. Extended pump shaft also ensures the stability of the pump in operation, to avoid excessive wear and tear of mechanical parts.
3. Low vibration and low noise operation: the pump uses high-quality bearings of well-known brands to ensure the smooth operation of the pump. The precision design of the bearings effectively reduces the vibration and noise of the pump in operation, thus enhancing the working comfort of the pump and the overall performance of the equipment. Low vibration and low noise not only extends the service life of the pump, but also reduces the impact on the surrounding environment, suitable for use in demanding industrial or commercial environments.
4. Single suction, single stage horizontal centrifugal pump design: the pump adopts a single suction, single stage horizontal centrifugal pump structure, combined with a closed impeller and pump body design. This design not only improves the pump’s conveying efficiency, but also effectively reduces energy loss. The single suction design allows the pump to draw in liquid on one side, which is suitable for a variety of liquid transportation applications, ensuring the pump’s high efficiency and stability.
5. Coaxial direct structure: cooling tower pump using coaxial direct structure, the motor and pump body directly connected. Compared with the traditional drive, this design greatly simplifies the structure of the pump, reduces the size of the equipment, reduces the weight of the pump. At the same time, the direct drive system also improves the efficiency and reliability of the pump, reducing the difficulty of maintenance.
6. Mechanical seal and long-term service life: the pump is equipped with a high-efficiency mechanical sealing system, which can ensure that the shaft center is not damaged, avoiding the risk of pump leakage and extending the service life of the pump. Mechanical seal can effectively prevent the leakage between the inside of the pump body and the outside world, which ensures the safe transportation of liquid.
7. High performance and not overload: cooling tower pump in the design of high performance and overload protection, the pump’s power consumption will not exceed the rated power. This means that the pump can run stably at any working point of its performance curve without overloading, thus ensuring the safety and reliability of the equipment under long-time operation.
8. Customizable materials: according to customer needs, the pump can be made of different materials for the pump body, impeller and seals, to adapt to the working requirements of different environments and media. For example, in corrosive media or high temperature environment, the pump can be corrosion-resistant, stainless steel and other materials to enhance its durability and stability.

cooling tower pumps are mainly used in evaporative condensers and large-scale industrial cooling systems, and are also suitable for occasions requiring high flow and low head water circulation. Its typical applications include:

1. Evaporative condenser supporting the use of: evaporative condensation pump is used to collect water in the tank through the spray pipe to the top of the evaporative condenser, through the nozzle sprayed to the outside surface of the condensate drain tube. The water forms a thin film on the surface of the condenser tube and part of the water absorbs heat and evaporates, carrying away the heat and thus cooling the refrigerant from a gaseous state to a liquid state. This process is crucial for efficient heat exchange.
2. Air conditioning system cooling: in the cooling process of air conditioning systems, cooling tower pumps are used to maintain the flow of liquid in the condenser to ensure that the system can continue to dissipate heat effectively. This helps to improve the cooling efficiency of the air conditioning system and saves energy consumption.
3. Industrial cooling system: in large industrial equipment and cooling towers, cooling tower pumps are responsible for water circulation and transportation, to help take away the heat from the high temperature equipment. This is crucial for industries such as steel, power, and chemical, as the equipment in these industries usually requires an efficient cooling system to maintain normal operation.
4. Boiler feed water system: cooling tower pumps can be used as supporting equipment for boiler systems, responsible for conveying circulating or cooling water to maintain the heat exchange efficiency of the boiler and prevent overheating damage to equipment.
5. Large flow and low head applications: the pump is especially suitable for those occasions that require large flow and low head, such as some special cooling or water circulation systems. The low head feature allows the pump to maintain efficient operation while providing a high flow of water.

Evaporative condensers utilize the process of evaporation of water to carry away heat, thereby cooling the gaseous refrigerant into liquid form. Its basic principles are as follows:

1. Spray water circulation: the water pump will collect water in the tank to the top of the condenser spray pipe, through the nozzle evenly sprayed on the surface of the condensing tube, forming a thin film of water. Part of the water in the water film absorbs heat and evaporates, thus taking away the heat of the refrigerant in the tube, so that the refrigerant is gradually cooled from the gaseous state to the liquid state.
2. Hot air discharge: axial fan forced air from the condenser top and side wall inhalation, and heat exchange with the water film. The hot and humid air is discharged to the external atmosphere after passing through the packing. In order to effectively prevent water droplets from drifting away, the skimmer traps the water droplets and ensures that the water loss is very low and the drift rate of water vapor is almost zero.
3. Water cycle replenishment: the system controls the replenishment of water vapor through a float valve to keep the water volume and level of the system stable and ensure the continuity of the condensation process.
