Don't panic if the refrigeration compressor suddenly stops, remember these methods!

What should be paid attention to when the refrigeration compressor stops abnormally? Some friends may not understand it. Let's take a look at it with everyone today!

1 Sudden power failure
If there is a sudden power failure while the refrigeration compressor is running, first turn off the power switch and immediately close the suction valve and exhaust valve of the compressor. Too much liquid causes wet compression.

2 Sudden water 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 refrigeration compressor failure shutdown
When the compressor needs to be shut down due to damage to a part of the compressor, it can be operated as normal shutdown if time permits. If the situation is urgent, the power of the motor should be cut off and the suction and exhaust valves and liquid supply valves should be closed. 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 Stop in case of fire
If a fire in an 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, and the emergency ammonia unloader and its water valve should be quickly opened. The ammonia liquid of the system is concentrated and discharged at the emergency ammonia discharge port and diluted by a large amount of water to prevent the spread of fire and explosion.

5 wet stroke stop
If the wet stroke of the refrigeration compressor occurs during operation, it should be treated separately according to its severity. For the 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.
