Industrial chiller commonly used in the market, I believe that everyone has learned some of his related knowledge. Simpson chiller manufacturers will share with you today how to maintain the chiller after using it for a period of time, replace the lubricant, dry the filter and clean the evaporator. What needs attention.


1.Change lubricant


After long-term use of industrial cooling chiller , the oil quality of the lubricating oil in the machine will become worse, and the impurities and moisture inside the oil will increase. Therefore, the lubricating oil in the machine should be replaced regularly. Be sure to use the same grade of lubricant.
 
2.Replace the drying filter


The drying filter in the chiller is an important part to ensure the normal circulation of the refrigerant. Because the water and refrigerant in the system are mutually exclusive. ; If the system in the chiller contains a certain amount of water, it will greatly affect the operating efficiency of the chiller in the later stage. Therefore, it is very important to keep the system dry during use. The filter element inside the drying filter must be periodically required. replace.
 
3. Cleaning of condenser and evaporator


Since the cooling water of the water-cooled condenser is an open circulation circuit, the tap water generally used is circulated and used by the cooling tower. When the content of calcium and magnesium salts in water is large, it is easy to decompose and deposit on the cooling water pipe to form scale, which affects heat transfer. Excessive scaling will also reduce the cross-section of the cooling water, reduce the amount of water, and increase the condensation pressure. Therefore, when the quality of the cooling water used is poor, the cooling water pipe is cleaned at least once a year to remove scale and other dirt in the pipe. There are two ways to clean the condenser water pipes:


(1) Use a special pig to clean the pipe;


(2) Use a special cleaning agent for the chiller to cycle the rinse, or fill it with cooling water, and then replace the solution after 24 hours until the rinse is clean
