Cause Analysis And Solution Of Several Faults Of Compressor

Cause Analysis and Solution of Several Faults of Compressor

1. Compressor failure:

1. First check whether the compressor can start normally, and check whether the voltage of the compressor is normal.

2. If the voltage is normal, check the static resistance. Whether the static resistance voltage is balanced and stable. If the resistance is unbalanced, then see if the motor unit is shorted. Is there a problem with the winding. If the resistance is stable, check whether the temperature of the compressor is also stable. If the temperature is too high, it needs to cool down for a while. Try again in 2-3 hours.

3. If everything is normal, check whether the bearing is healthy.

2. The compressor is noisy.

1. Check whether the screws of the compressor are firm, slipped or collapsed.

2. Test whether the current is stable. Is it too high.

3. If the injection volume of the compressor is too large, check the cooling effect of the compressor to see if it is overheated.

4. Check whether the compressor is reversed. Whether the compressor has aged and damaged.

3. Insufficient suction and exhaust pressure.

1. If the suction and exhaust pressure is found to be low or high, it is generally a problem with the chiller system.

2. When the exhaust pressure is low, is the defrosting system normal? If there is noise during defrosting, it is normal.

4. Current

1. The current inspection can not only be limited to the compressor, but also whether the voltage of the motor itself is stable.

2. Check the one-way valve, oil content, and whether such originals are normal.
