When using the scotch yoke pneumatic actuator, it is easy to damage or break down if it is not carefully maintained in the use process, thus reducing the service life of the scotch yoke pneumatic actuator.
In the maintenance of the fork pneumatic device, timely measures should be taken to reduce and prevent the occurrence of faults and prolong the service life of components and systems. Therefore, enterprises should formulate management standards for maintenance of pneumatic devices, strengthen management education and strict management.

The central task of maintenance is to ensure the supply of clean and dry compressed air to the pneumatic system, the air tightness of the pneumatic system, the necessary lubrication of oil mist lubricating elements, and the specified working conditions (such as pressure, voltage, etc.) for the pneumatic actuator to work according to the predetermined requirements.

Oil sprayer is best to choose the specification of once-a-week refueling. When refueling, attention should be paid to the reduction of oil quantity. If the fuel consumption is too small, the oil dropping amount should be readjusted. After adjustment, the oil dropping amount should be reduced or not. The import and export of the oil mist should be checked for reverse loading, whether the oil passage is blocked, and whether the specifications of the selected oil mist are appropriate.
The monthly quarterly maintenance work should be more careful than the daily and weekly maintenance work, but it is still limited to the scope that the external vibration disc department can check. Its main contents are: carefully check the leakage situation everywhere, tighten the loose bolts and pipe joints, check the air quality of the reversing valve, check the flexibility of the regulating parts, check the correctness of the indicator, check the reliability of the electromagnetic valve switching action, check the quality of the cylinder piston rod and everything that can be checked from outside.
Maintenance can be divided into regular maintenance and regular maintenance. The former refers to the daily maintenance work, the latter can be weekly, monthly or quarterly maintenance work. Maintenance should be documented. Maintenance work should be recorded to facilitate future fault diagnosis and treatment.
Correct maintenance can effectively prolong the service life of scotch yoke pneumatic actuator in the process of using fork pneumatic execution mechanism.
