Six Reasons for Compressor Damage in Constant Temperature and Humidity Test Chamber

The compressor faults of the engine (hereinafter referred to as the compressor) can be divided into motor faults and mechanical faults (including crankshaft, connecting rod, piston, valve plate, cylinder head gasket, etc.).


There are three common faults in the compressor of the constant temperature and humidity test chamber: 1. The motor is burnt out; 2. Liquid hammer; 3. Lack of oil caused by refrigeration oil.


Mechanical failures often cause the motor to run overloaded or even stall, which is one of the main reasons for motor damage. The main manifestations of motor damage are: damage to the insulation layer of the stator winding (short circuit) and open circuit. It is difficult to detect damage to the stator winding in a timely manner, which may ultimately lead to the burning of the winding. After the winding is burned out, some phenomena or direct causes that caused the burning are covered up, making it difficult to analyze and investigate the causes afterwards.


Starting from these aspects, it can be found that the compressor failure in the constant temperature and humidity test chamber is caused by the burning of the winding:


1. Abnormal load and locked rotor;


2. Short circuit of winding caused by metal chips;


3. Contactor issues;


4. Power supply phase loss and abnormal voltage;


5. Insufficient cooling;


6. Use a compressor to vacuum.
