Pay attention to keep the compressor lubricating oil clean

Pay attention to keep the compressor lubricating oil clean Why should we pay attention to keeping the compressor lubricating oil clean? This is because the dirty oil of the compressor or the deteriorated lubricating oil will cause a vicious cycle of accelerating the wear of the parts. Therefore, we should clean the lubricant oil of the compressor according to the following requirements:

Refrigerator compressor working principle, wiring diagram, structure

The core component of the refrigerator is the compressor. If there is no compressor with good quality and technology, it is not a good refrigerator. At present, many products on the market advertise the use of high-quality compressors, so which compressor brands are in China, and which failures are prone to occur? I will introduce you one by one in the following!
