The maintenance and operation of diaphragm compressors Diaphragm compressor is a high purity gas compression equipment. Diaphragm compressors do not use lubricating oil, so they do not pollute the compressed gas, making them very suitable for applications that require extremely high gas purity. Due to the isolation effect of the diaphragm, the mechanical equipments inside the gas compressor will not come into direct contact with the compressed gas, greatly reducing the risk of explosion caused by sparks or high temperatures caused by friction. Diaphragm compressor as a more sophisticated mechanical equipment, in addition to its normal operation, maintenance to be thoroughly familiar with the heart, but also to its sealing and other special functions and roles, resulting in production safety accidents and personal safety accidents.
