How to judge the fault source of the noise and vibration of the chiller compressor

1. The compressor is overloaded.

Overloading and overloading can easily cause abnormal changes in the vibration and noise of the compressor, or abnormal noise and vibration. At this time, the operation and maintenance personnel of the chiller can find that the vibration and noise of the compressor are significantly higher than usual, and It is intermittent, so it can be judged that the compressor is overloaded.

The overload of the compressor will definitely cause abnormal noise and vibration, and the abnormal noise and vibration are not necessarily caused by overload.

2. Lack of oil and liquid entering the working chamber of the compressor.

In addition to overloaded operation, the compressor lacks lubricating oil, liquid refrigerant enters the compressor, or the water content of the refrigerant is too high, which will also cause the compressor to produce abnormal vibration and noise, as well as the compressor noise and vibration under normal operating conditions. produce certain distinctions and differences.

3. The installation position of the chiller itself is not flat, the screws on the bracket of the chiller and the ground are loose, the screws on the bracket of the compressor and the chiller are loose, etc., which will also cause abnormal vibration and noise of the compressor. These are all common. The fault source of the compressor noise and vibration can be checked in turn, and the problem can be dealt with immediately after the problem is identified.
