1. Compressor maintenance case analysis Recently, a customer in the factory sent a screw compressor for repair. The customer reported that the machine had a low oil pressure and the equipment was stopped, and then the equipment was stuck. After disassembly inspection by the maintenance department, it was found that the radial and axial bearings of the exhaust end of the male rotor were damaged due to oil deficiency, and the oil holes of the oil injection plate were also blocked. It was analyzed that the direct cause of bearing damage was that the customer did not replace the old oil filter in time during use, causing the residual impurities inside the oil filter to enter the oil circuit system as the equipment operates. Since the injection plate is located at the end of the oil circuit system and the diameter of the injection hole is small, these impurities can easily clog the injection hole, causing a series of failures.
