Vapor pressure and solution concentration

Screw compressor is a positive displacement compressor from the mechanical type, which is composed of the driving rotor and driven rotor, the main body and a pair of synchronous gears. Therefore, the common faults of screw compressor are as follows: 1. The bearing is burnt out. Because of the foreign matter in the oil system, the oil pressure and the quality of the oil are reduced, resulting in the bearing burning out. The main treatment methods are: check the oil supply system; clean the oil filter and the cooling pipe of the oil cooler; check and adjust the oil pressure regulating valve; test the oil quality, and replace the oil when it is not good; check and deal with the oil leakage points. 2. The rotor is burnt out. When foreign matters enter into the compressed medium system, the temperature of the rotor rises, the temperature of the cooling oil of the rotor increases due to the high temperature of the inhaled medium, and the compression ratio increases, which may cause the
