Treatment method of ammonia leakage accident in ammonia refrigeration compressor

During the operation of the cold storage, the maintenance and maintenance of the ammonia refrigeration system are not in place, which will cause some failures in the ammonia refrigeration system. Ammonia leakage is one of the common failures in the maintenance of ammonia refrigeration machines. Let’s talk about After the ammonia leaks, some necessary emergency treatment plans.

1. After an ammonia leakage accident occurs in the ammonia compressor, first cut off the compressor power supply and immediately close the exhaust valve and suction valve (two-stage ammonia compressor should close the secondary exhaust valve and secondary suction valve at the same time) if it is refueling , The fueling valve should be closed in time.

　　2. All the machines running in the ammonia refrigeration system room should be stopped. When the operator finds that the compressor is leaking ammonia, stop immediately and according to their location, turn off the nearby machines when the accident machine is turned off.

　　3. If the ammonia leakage refrigeration accident is serious and the accident machine cannot be approached, the machine should be shut down outdoors, and immediately close all the inlet valves of the oil-ammonia separator and the low-pressure barrel outlet valve connected to the suction of the accident machine.

　　 4. Quickly turn on all emergency exhaust fans in the ammonia compressor room.

　　5. When dealing with an ammonia refrigeration system accident, spray the leaking ammonia part with a water pipe to dissolve the ammonia and water. Pay attention to the waterproof protection of the compressor motor.
