Stable discharge temperature and lubricating oil quality are the keys to the normal operation of cold storage compressors. Among them, excessively high discharge temperature and accelerated oil deterioration are core hidden dangers that easily cause compressor failures and affect unit service life, directly related to the stable operation of the refrigeration system.
Excessively high discharge temperature will exceed the normal working range of the compressor, intensify the wear of internal components, reduce the compression efficiency of the compressor, and at the same time increase the overall operating temperature of the unit, indirectly affecting the heat exchange effect of components such as condensers and evaporators, and increasing energy consumption.
Lubricating oil is the "blood" of the compressor. Excessively high discharge temperature will accelerate oil deterioration, leading to a decrease in lubricating oil viscosity and a decline in lubricating performance, which cannot effectively protect the internal moving components of the compressor, causing component wear, cylinder sticking and other failures, and greatly shortening the service life of the equipment.
The two affect each other and form a vicious circle, which will increase maintenance costs and the probability of fault shutdown, and affect the normal refrigeration of the cold storage. It is necessary to timely investigate the causes of excessively high discharge temperature, standardize unit operating parameters, regularly replace high-quality lubricating oil, eliminate such hidden dangers, and ensure the stable and efficient operation of the compressor.
