Whether frozen water pump or cooling water pump, including the boiler with the water pump, as long as it is used for replenishment, are called water pump. Normally, the pump works intermittently.
The make-up water pump is neither a chilled water pump nor a cooling water pump. It is a water pump for the water supply of the chilled water system.
A water pump that automatically or manually supplies water to the water system when the amount of water in the water system decreases (evaporation, overflow, etc.), and does not belong to a chilled water pump or a cooling water pump.
Cooling water pumpDetermination of water replenishing pump1) the hourly flow is 4%~5% and the total water quantity is.2) the lift is the replenishment point and the pressure is plus 30~50 kPa.3] water pump to overcome the pressure of the replenishment point and the pressure difference between the make-up water tank, during which the pipeline is not long, you can ignore its resistance4) open system replenishment, no replenishment pump
