Shifting scotch yoke pneumatic actuator is difficult to avoid in use because of its poor working environment. The most common packing scotch yoke pneumatic actuator is packing leakage.

Scotch yoke pneumatic actuator stem packing leakage is more common, there are loose parts, valve corrosion, filter pressure relief valve damage, membrane leakage, etc., in view of these operational risks, Beijing Rui Tuo company established a pneumatic actuator operation inspection and repair system. Aiming at loosening parts, corrosion of valve body, damage of filter pressure reducing valve and leakage of membrane head, Central Plains Dahua has established spot inspection and repair system.

Spot inspection and repair is to check the equipment according to a certain standard, a certain period, to find out the hidden trouble of the equipment early, to repair and adjust in time, so that the equipment can maintain its specified function. Combined with the actual situation and grading management according to the influence degree and importance of the instrument to the production, the spot inspection and repair standards and corresponding assessment methods were formulated. Request the inspector to check all the instruments in the package area one by one in accordance with the spot inspection standards 5 days before the month, collect and analyze the spot inspection data, find out the problems existing in the instrument, and then adopt the "five fixed" method of "setting the time, setting the responsible person, setting rectification measures, fixing funds and setting measures" to track the hidden danger of the instrument thoroughly. The spot inspection and repair system can detect hidden dangers in time and eliminate hidden dangers in the bud by five. The checklist for the operation of pneumatic actuators is shown in Table 1.
When the scotch yoke pneumatic actuator occurs packing leakage event, the staff can repair and repair according to the above contents. If you have the need to scotch yoke pneumatic actuator, please call us.
