    Notes on abnormal shutdown of refrigeration compressor

    Notes on abnormal shutdown of refrigeration compressor Abnormal shutdown is generally an accident shutdown, mainly in the following situations. 1) Sudden power failure and shutdown. If the refrigeration compressor is suddenly powered off, you should first cut off the power switch and immediately close the compressor suction valve and exhaust valve, and close the liquid supply valve at the same time to stop the supply of liquid to the evaporator. When the machine is started for the second time, there is too much liquid in the evaporator and wet compression occurs. 　　 2) Sudden water stop and shutdown, if the cooling water is suddenly interrupted, the power supply should be cut off immediately, and the operation of the refrigeration compressor should be stopped to avoid excessive pressure of the condenser. After the compressor is stopped, the suction and exhaust valves and related liquid supply valves of the compressor should be closed immediately, and the fault should be eliminated after the cause is found, and then restarted after the water supply is restored. 3) When the refrigeration compressor fails to shut down and needs to be shut down due to damage to a part of the compressor during re-operation, it can be operated as normal shutdown if time permits. If the situation is urgent, the motor power should be cut off and the suction and exhaust valves should be closed. And liquid supply valve. If the refrigeration equipment runs ammonia or the refrigeration compressor fails, the workshop power supply should be cut off and wear anti-virus clothing and masks for urgent repairs. At this time, all exhaust fans should be turned on, and if necessary, water can be poured to leak ammonia to facilitate emergency repairs. 4) When the fire is shut down, if the fire in the adjacent building endangers the safety of the refrigeration system, the power supply should be cut off, and the exhaust valves of the accumulator, condenser, ammonia oil separator, and evaporator should be quickly opened to quickly open the emergency discharge The ammonia device and its water valve make the ammonia liquid of the system concentrated at the emergency ammonia discharge port and be diluted by a large amount of water to prevent the spread of fire and explosion. 　　 5) When the wet stroke is stopped, if the wet stroke of the refrigeration compressor occurs during operation, it should be treated separately according to its severity. For slight wet stroke, the suction valve or expansion valve should be closed or closed. For more serious wet travel, shut down the suction valve and expansion valve immediately. After a serious wet stroke occurs, the refrigerant in the crankcase should be released, or other refrigerant compressors should be used to draw out the refrigerant in the crankcase and cylinder, and the lubricant should be replaced at the same time. Start the test machine.
