The chiller consists of three interrelated systems: refrigerant circulation system, water circulation system, and electrical automatic control system.
The chiller is a kind of water cooling equipment, which can provide cooling water equipment with constant temperature, constant current and constant pressure.
Common auxiliary accessories for chillers include water flow switch, pressure controller, differential pressure controller, temperature controller and solenoid valve.
The above situations are the common reasons for the failure of the water pumps, but they are not all the reasons for faults of pumps. To deal with the failures in practice, the principle of first outside and then inside should be followed, and no blind operation should be performed.
During the operation of the water pump, it is inevitable that failure and damage will occur, so that it cannot operate normally. The following summarizes the common troubleshooting and maintenance methods of the water pumps.
The flow rate of the pump during operation is restricted by the lift. The higher the pump lift, the smaller the flow. If the head is fixed and you want to reduce the flow,the way to adjust the flow and save power is to use frequency conversion speed regulation.
