If a set of pneumatic devices is not maintained properly, they will be damaged prematurely or fail frequently, greatly shortening the service life of the device. When maintaining pneumatic devices, timely measures should be taken based on the signs of accidents discovered to reduce and prevent the occurrence of faults, and to extend the service life of components and systems. Therefore, enterprises should establish component maintenance management standards, strengthen management education, and strictly manage. The central task of maintenance work is to ensure the supply of clean and dry compressed air to the pneumatic system, the airtightness of the pneumatic system, the necessary lubrication of oil mist lubrication components, and the specified working conditions of the pneumatic components and system, in order to ensure that the pneumatic actuator operates according to the predetermined requirements.
