Chillers, as a kind of industrial equipment, are bound to have common failures, just like a car, some problems will inevitably occur after a long time of use. Among them, the serious situation is that the chiller suddenly shuts down. Once this situation is not handled properly, it may cause serious accidents. Now let me take you to understand that the compressor of the chiller suddenly stops, how should we deal with it?
1. Sudden power failure causes the chiller to shut down
During the operation of the refrigeration compressor, if there is a sudden power failure, first disconnect the main power switch, immediately close the suction valve and discharge valve of the compressor, and then close the liquid supply gate valve to stop the liquid supply to the air conditioner evaporator, so as to prevent the cold water from running next time. When the machine is installed, the humidity of the air conditioner evaporator shrinks due to excessive liquid.
2.the sudden water cutoff caused the chiller to stop.
If the refrigeration circulating water is cut off suddenly, the switching power supply should be cut off immediately, and the operation of the refrigeration compressor should be stopped to prevent the working pressure of the refrigerator from being too high. After the air compressor is shut down, the suction and exhaust valves and related liquid supply valves should be closed immediately. After the cause is found out and common faults are eliminated, the chiller should be restarted after the power supply is repaired.
3. Shut down due to common faults of chiller compressors
When the chiller is in urgent need of shutdown due to damage to some parts of the compressor, if conditions permit, it can be operated according to normal shutdown. Liquid supply gate valve. If the refrigeration equipment is short of ammonia or the refrigeration compressor is faulty, the power supply of the production workshop should be disconnected, and protective clothing and masks should be worn for maintenance. At this point, all exhaust fans should be turned on. If necessary, tap water can be used to drain the ammonia leakage location, which is convenient for maintenance of the chiller.
4. Stop on fire
In the event of a fire in an adjacent building, the stability of the refrigeration unit is seriously threatened. Turn off the power, quickly open the exhaust valves of the liquid storage tank, refrigerator, ammonia oil filter, air-conditioning evaporator, etc., quickly open the emergency ammonia unloader and water inlet valve, so that the ammonia solution of the system software is discharged at the emergency ammonia unloading port. Dilute with plenty of water to prevent fire accidents from spreading and causing accidents.
The maintenance of the chiller is a relatively technical matter. To solve the common faults of the chiller, a technician must be hired. It is very risky to solve it without authorization.
