Compressor Component Wear / Seal Failure — A One-Minute Troubleshooting Guide

Compressor Component Wear / Seal Failure — A One-Minute Troubleshooting Guide

The compressor is the 'heart' of the refrigeration system, relying on the operation of internal components and sealing performance to ensure the circulation of refrigerant. If internal components are worn or the seal fails, suction efficiency will drop significantly, making it unable to draw refrigerant from the evaporator. This directly leads to low suction pressure, followed by insufficient discharge volume and rising machine temperature during operation.

Common Causes:

Wear and aging of internal compressor components such as pistons and valve plates
Damaged seals causing gas leaks

Quick Troubleshooting:

Listen for sounds: Are there abnormal noises or impact sounds during operation? (Indicates component wear)
Feel the temperature: Is the machine abnormally hot?
Check parameters: Compare with normal operating conditions to confirm low suction pressure and insufficient discharge volume

Conclusion

Do not force the compressor to run if core components are faulty. Timely maintenance, replacement of worn parts, or seals can restore circulation efficiency, prevent the compressor from burning out due to overload, and extend the overall service life of the equipment.
