Lack of oil can cause severe lack of lubrication , the root cause lies not in lack of oil compressor oil how much Ben and speed, but the system back to the oil well. Oil separator can be installed quickly back to the oil , extending back to the oil -free compressor run time . Evaporator and return line must be designed to take into account the oil return . Avoid frequent start , timed defrost replenish refrigerant , timely replacement of worn piston assembly and other maintenance measures also contribute back to the oil .

 

Liquid refrigerant migration back and will dilute the oil is not conducive to the formation of the oil film ; pump failure and oil blockage affects the amount of oil and oil pressure , causing friction surface starvation ; friction surface temperature will lead to oil decomposition, so that oil loss of lubricating ability . Insufficient lubrication problems caused by these three aspects are often caused by damage to the compressor .

 

Root cause lies in the lack of oil system . Therefore , only replace the compressor or some parts can not solve the problem fundamentally starvation .
