Air conditioning compressor

Abnormal noise

As a moving part rotating at high speed, the air conditioning compressor has a high probability of failure. Sound is a common fault.

There are many reasons for abnormal noise in the compressor. For example, the electromagnetic clutch of the compressor is damaged, or the internal wear of the compressor is large, etc., which may produce abnormal noise.

2. The electromagnetic clutch of the compressor is a common part where abnormal noise occurs.

The compressor often works from low speed to high speed under high load, so the requirements for the electromagnetic clutch are very pupil. In addition, the installation position of the electromagnetic clutch is generally close to the ground and is often exposed to rain and soil. When the electromagnetic clutch bearings are damagedaged, abnormal noise will be produced.

3. The tightness of the compressor transmission belt also directly affects the life of the electromagnetic clutch.

If the transmission belt is too loose, the electromagnetic clutch will slip easily if the transmission; the belt is too tight, the electromagnetic clutch will slip. The load on it will increase. Improperly tightening the drive belt can at least prevent the compressor from working, or at worst damage it. When the transmission belt is working, if the compressor pulley and the generator pulley are not in the same plane, the service life of the transmission belt or compressor will be reduced.

4. Repeated operation of the electromagnetic clutch will also cause abnormal noise in the compressor.

For example, the power generation capacity of the generator is insufficient, the pressure of the systemThe air conditioning is too high or the engine load is too high. This will cause the electromagnetic clutch to engage repeatedly.

5. The gap between the electromagnetic clutch and the compressor mounting surface

There must be a certain gap between the compressor mounting surface of the electromagnetic clutch. If the gap is too big, the impact will also increase. If the gap is too small, movement interference will occur between the electromagnetic clutch and the compressor mounting surface during operation, which is also a common cause of abnormal noise.

6. The compressor needs reliable lubrication when it is working.

When the compressor lacks lubricating oil or the lubricating oil is used improperly, severe abnormal noises will occur at the compressor. inside the compressor and will even provide reliable lubrication. Compressor wear.
