Common Faults of Scroll Chiller Compressor

The liquid hammer of the scroll compressor can cause damage to the scroll. The failure phenomenon is generally manifested as the obvious metal impact sound inside the compressor. This is when the metal fragments after the scroll is crushed collide with each other or compress The sound of the machine casing impact.

There are three main situations for liquid shock:

One is that a large amount of refrigerant liquid enters the compressor at the moment of startup;

Second, the evaporator flow is not enough (the saving load is reduced), and the compressor has liquid back phenomenon;

Twazyèmman, ponp chalè inite a pa travay byen pou dekonjle, yon gwo kantite febrifuj likid antre nan COMPRESSOR san yo pa evapore, oswa likid la nan evaporate a antre nan COMPRESSOR nan moman sa a lè valv la kat-fason chanje direksyon.

How to solve the problem of liquid strike or liquid return?

1. Nan konsepsyon kanalizasyon an, evite refrijeran likid antre nan COMPRESSOR a lè kòmanse moute, espesyalman sistèm nan refrijerasyon ak yon chaj relativman gwo. Ajoute yon separasyon gaz-likid nan pò aspirasyon COMPRESSOR se yon fason efikas pou rezoud pwoblèm sa a, espesyalman nan inite ponp chalè ki itilize dekonjle gaz cho inverse.

2. Before starting the machine, preheating the oil cavity of the compressor for a long enough time can effectively prevent a large amount of refrigerant from accumulating in the lubricating oil. It also has a certain effect on preventing liquid shock.

3. The water system flow protection is indispensable, so that when the water flow is not enough, it can protect the compressor, and the evaporator will be damaged if the unit has liquid back phenomenon or severely freezes.
