The reasons for the wear of the crankshaft in a piston-type refrigeration compressor may include oil quality, mechanical issues, operational management, etc. Of course, a specific analysis is needed based on the specific situation.

The reasons for the wear of the crankshaft in piston-type refrigeration compressors may include aspects such as oil quality, mechanical factors, and operational management, which need to be analyzed based on specific situations. Among them, the quality of refrigerant oil is one of the main factors affecting crankshaft wear. Piston-type refrigeration compressors operate at high speeds, under heavy loads, and with high discharge temperatures. If the viscosity of the oil is too low or the cleanliness of the lubricant is not high enough, it can lead to abnormal wear or even damage to the crankshaft. Additionally, during operation, if there is mixing of oils and liquid refrigerants entering the crankcase mix with refrigerant oil and create foam, it can reduce lubrication effectiveness at various friction points, thereby exacerbating wear. Furthermore, bearing shells and connecting rod bearings are made from babbitt alloy; if metal particles from their wear are present in the refrigerant oil, it will further accelerate crankshaft wear.
