Causes and solutions of “occasional hydraulic shock” in the chiller

1. Liquid enters the system, especially the compressor.

Liquid hammer Liquid hammer, as the name implies, is that non-gas refrigerant liquid (including water, refrigerant, refrigerated lubricant, etc.) enters the refrigerator system. When moisture enters the compressor working cavity, liquid hammer will naturally occur. Investigate the reason, the liquid may be because the filter drier needs to be replaced, the evaporator fails, the gas-liquid separator does not work properly, and the refrigerated lubricating oil system fails, etc.

2. Too much refrigerant is added to the compressor of the refrigerator.

When there is too much refrigerant in the freezer system, whether it is an evaporator or a condenser, it may not be able to meet the requirements of maintaining the normal operation of the freezer system, which may lead to failures.

Solution:

Once the refrigerator compressor faces an occasional liquid hammer failure, the maintenance personnel should immediately stop the machine for handling. However, as long as there are various problems or phenomena mentioned above, the liquid hammer failure of the refrigerator compressor will no longer be an accidental failure, and may become a multiple problem.
