Causes of Compressor Common Failures and Countermeasures Analysis

Abstract: During the operation of the compressor, some failures and even accidents will inevitably occur. A fault refers to an abnormal condition that occurs during the operation of the compressor, which can be restored to normal operation once the compressor is eliminated, while an accident refers to a damage situation. The two are often related, and if the fault is not eliminated in time, it will cause a major accident.

[Experience] What happens if the compressor suction pressure is too high and the discharge pressure is too high

[Experience] What happens if the compressor suction pressure is too high and the discharge pressure is too high Compressor suction pressure is too high, discharge pressure is too high 1. Too much refrigerant. Too much refrigerant will cause the suction pressure and discharge pressure to be too high at the same time. This is because when too much refrigerant fills the reservoir, it will occupy a part of the condenser volume, reducing the heat dissipation area and causing the condenser Poor condensation. Discharge excess refrigerant from the low-pressure side.
