leyu乐鱼体育官网1. Frozen water pump
A device that drives water to circulate in a frozen water loop. The end of the air-conditioned room needs the cold water provided by the chiller, but the chilled water will not flow naturally due to the limitation of the resistance. This requires the pump to drive the chilled water to circulate to achieve the purpose of heat transfer.
leyu乐鱼体育官网2. Cooling water pump
leyu乐鱼体育官网A device that drives water to circulate in a cooling water loop. We know that the cooling water takes away a part of the heat from the refrigerant after entering the chiller, and then flows to the cooling tower to release this part of the heat. The cooling water pump is responsible for driving cooling water to circulate in the closed loop of the unit and the cooling tower.
leyu乐鱼体育官网3, water replenishment pump
The equipment used for the water supply of the air conditioner is responsible for the softening of the treated water into the system. The shape of the same water pump.
Commonly used pumps are horizontal centrifugal pumps and vertical centrifugal pumps, which can be used in frozen water systems, cooling water systems and water replenishment systems. The horizontal centrifugal pump can be used for the large area of the machine room, and the vertical centrifugal pump can be considered for the small area of the machine room.
leyu乐鱼体育官网When the pump runs in parallel, the flow rate is attenuated; when the number of parallel lines exceeds 3, the attenuation is particularly severe. Suggestion:
1. When a number of pumps are selected, the attenuation of the flow is considered, and the allowance for 5% to 10% is generally added.
2. It is not suitable for more than 3 pumps in parallel, that is, it is not suitable for more than three units to choose the main engine.
leyu乐鱼体育官网3. Cold and hot water circulation pumps should be set up for large and medium-sized projects.
leyu乐鱼体育官网The above is the knowledge that Xiao Bian tells you. We have strict working attitude and skilled working skills. We will ensure that tasks are done accurately and efficiently.
