Pneumatic implementation of the original fault handling approach Pneumatic

Pneumatic implementation of the original fault handling approach Pneumatic actuator failure Due to improper assembly and long-term use of the cylinder, the pneumatic actuator is prone to internal and external leakage, the output force is not enough and the action is not smooth, poor cushioning effect, pneumatic piston rod and cylinder head damage and other symptoms. 1. Cylinders appear inside and outside the leak, usually due to eccentric piston rod installation, lack of oil supply, seals and seal rings wear or damage, the cylinder impurity and the piston rod caused by scars and so on. Therefore, when the cylinder inside and outside leakage, should re-adjust the center of the piston rod to ensure the concentricity of the piston rod and cylinder; must always check the reliability of the work of the lubricator to ensure good lubrication of the implementation of components; pneumatic punch When the seal ring and seal ring wear or damage ring, must be promptly replaced; if there is impurity in the cylinder, should be promptly removed; piston rod scars, should be renewed.

2. Cylinder output and lack of action is not smooth, the general pneumatic punch is due to the piston or piston rod is stuck, poor lubrication, lack of air supply, or the cylinder with condensed water and impurities and other reasons. In this regard, the center of the piston rod should be adjusted; check the operation of the oil mist is reliable; air supply pipe is blocked. When the cylinder has condensed water and impurities, should be promptly removed. 3. cylinder cushioning effect is poor steel punching machine, usually due to buffer ring wear or damage caused by adjustment screw. In this case, replace the seal ring and adjustment screw. 4. Cylinder piston rod and cylinder head damage, usually due to eccentric piston rod or buffer mechanism does not work caused by drilling machine suppliers. In this regard, adjust the center of the piston rod position; replace the buffer seal or adjustment screw busbar machine.
