introduction:The compressor is in operation,Some glitches are bound to occur,Even accident。A fault refers to an abnormal situation that occurs during the operation of the compressor,The compressor can be restored to normal operation once it is removed,An accident is an indication of damage。The two are often related,If the failure is not removed in time, it will cause a major accident。 Compressors are used to increase gas pressure and transport gas machinery。From an energy point of view,Compressor is a machine that converts the power energy of the prime mover into the pressure energy of the gas。With the development of science and technology,Pressure energy is used more and more widely,Makes compressors in many sectors of national economic construction
