Symptoms of Broken Valve Blades in Household Air Conditioning Compressors

2023/6/19

Firstly, the fault phenomenon is that after being powered on, the compressor does not operate and the protector acts. Usually, it is caused by compressor oil loss or impurities entering, resulting in shaft or cylinder jamming faults.
Secondly, the fault phenomenon is that the suction and exhaust valves of the compressor are damaged, the system does not cool or the cooling effect is poor. Usually, it is a malfunction where the suction and exhaust valves of the air conditioning compressor are not tightly closed.
Thirdly, the fault phenomenon is: collision between the pipeline and the casing, loosening of the fixing bolts of the compressor, and detachment of the shock absorber block. This type of problem often occurs in maintenance work and generally has little impact on refrigeration performance.
Fourthly, the fault phenomenon is: open circuit or a decrease in the operating temperature point. This problem is often confused with a slight short circuit between turns in the winding. The difference is that when the thermal protector is damaged, the working current is normal, but when the winding is short circuited, the current is too high. Usually, it is a malfunction of the thermal protector of the air conditioning compressor.
Fifthly, the fault phenomenon is: when the circuit is open, the power supply is normal, the compressor is not working, there is a short circuit, and when the casing is touched, the protector acts or the fuse burns after being powered on. Usually, it is a short circuit, open circuit, and winding grounding fault in the air conditioning compressor, so it is not easy to determine. It should be determined based on the measured current.
