Why does the freezer need to be leak-tested?

When it comes to internal leak detection, it can be carried out by a compressor. Some dust removal, decontamination, and swarf removal work should be done first. Only after these are discharged, can the leak detection be effectively predicted and carried out. When detecting leaks, it is necessary to ensure that the refrigerator system is in a vacuum state. Basically speaking, leak detection can be carried out effectively only if it is close to a vacuum state.

Leakage of the freezer system is relatively common. If there are pipelines, valves, and other places leaking, the leak detection does not have to be done separately. It can also be done during the overall cleaning and maintenance of the system. , Simultaneously. Air tightness is very important to the refrigerator. After leak detection, it is necessary to refill refrigerant and refrigerating lubricant. When leak detection, the main detection is not large area, obvious leakage, but certain valves. , The slight leakage of the pipeline, because of the obvious leakage in a large area, can be detected by the naked eye or smell, and the refrigerant leak detector, while the slight exposure is difficult to detect.

During leak detection, the compressor should be loaded for no-load operation. In addition, each valve should be opened to allow the freezer system to run smoothly. The joints of each valve and pipeline should be smeared with special sealing liquid for leak detection. , Or self-made soapy water, after applying it, run the compressor for leak detection. After detecting a leak, it should be repaired in time. If there is a valve or pipeline that needs to be replaced, it should also be replaced in time to avoid leaks leading to poor operation of the refrigerator.
