Compressor common faults and maintenance methods

Reason 1: the compressor has been in high-pressure operation for a long time (high pressure is normally less than 2.5Mpa) specifically leading to a high-pressure operation of the original

A. pump with a small

B. Filter plug

C. water pipe diameter is small

D. elbow

C. Fluorine system blocked

D. Expansion valve opening is small

H. water temperature setting is high

I. water tank sensor failure or not plugged in

J. p>

H.Water temperature setting is high

I.Tank sensor failure or not plugged

J.Sets for scaling

Cause 2: The unit is in the state of exhaust gas is too high for a long time. Specific reasons:

A: lack of fluorine operation

B. Water flow rate is small

C. Expansion valve opening is small

D. Fluorine system half-blocked

E. Exhaust sensor failure (exhaust high, bad sensor, can not spray liquid)

F. Liquid injection valve failure (liquid injection valve valve or coil failure)

Cause three: Electrical control failure, specific causes:

A. AC contactor phase missing (AC contactor itself fault or wire loose)

B. Compressor wire loose or connected to the wrong line

C. Exhaust sensor failure

D. Pressure switch failure, shorted and not replaced in time.

Cause 4: System failure. Specific causes:

A. Excessive impurities in the fluorine system, causing the compressor to seize

B. Poor vacuum

C. Inaccurate fluoridation
