The compressor is a general-purpose mechanical equipment in industrial production, widely used in various sectors such as petroleum, chemical engineering, power metallurgy, mining, construction, light industry, pharmaceuticals, civil and national defense, and holds an important position in the national economy.

Diaphragm compressors are important gas compression equipment and are widely used in industries such as chemical engineering, petroleum, and pharmaceuticals. However, in actual operation, a relatively large vibration value of diaphragm compressors is a common problem, which not only affects the normal operation of the equipment but may also lead to equipment damage and production accidents.

The performance of a centrifugal compressor is influenced by the suction pressure, suction temperature, suction flow rate, the molecular weight composition of the intake air, and the rotational speed and control characteristics of the prime mover. It is most common for multiple causes to interact and lead to malfunctions or accidents. The possible causes and handling measures of common malfunctions are listed in the table below.
