The compressor is a universal type of mechanical equipment used in industrial production. It is widely applied in various sectors such as petroleum, chemical industry, power, metallurgy, mining, construction, light industry, pharmaceuticals, civilian use and national defense, and holds an important position in the national economy.

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

The performance of a centrifugal compressor is affected by the suction pressure, suction temperature, suction flow rate, composition of the intake gas molecules, and the rotational speed and control characteristics of the prime mover. Generally, situations where multiple causes interact to cause failures or accidents are the most common. The possible causes of common faults and the corresponding handling measures are listed in the table below.
