Six reasons for damage to compressors in high and low temperature test chambers

The common difficult problems of high and low temperature test chamber refrigeration units are as follows: 1.
Motor damage; 2.
Liquid hammer; 3.
Less oil caused by refrigeration oil
.

Take you to analyze the cause of motor damage
.

The common problems of high and low temperature test chambers, therefore, make the motor load run and even turn between turns, which is the key reason for the destruction of the motor
.

The specific manifestations of the damage of the motor are: the damage of the rotor winding insulation tube (the common problem of short-circuit faults) and the common faults of short-circuit faults
.

After the rotor winding is damaged, it cannot be detected immediately, and it is likely to cause winding damage later
.

After the winding is damaged, some of the conditions or root causes of the damage are blocked, and it is more difficult to promote future analysis and cause investigation
.

The difficult problems of high and low temperature test chamber refrigeration units start from these levels, it is not easy and difficult to find the reasons for the damage of windings, but there are only six kinds: (1) abnormal load and inter-turn detection; (2) caused by metal composite material chips Common faults of winding short-circuit faults; (3) Difficulties of DC contactors; (4) Phase failure of power transformers and abnormal working standard voltages; (5) Insufficient cooling water; (6) Vacuum packaging bags with refrigeration units;
