What if the oil leakage can't be eliminated?
It is very simple. The pneumatic butterfly valve can be pulled out to further check whether the clearance between the piston and the cylinder barrel is too large, whether the piston connecting rod of the pneumatic butterfly valve is bent, and whether the surface of the piston connecting rod and the cylinder barrel are scratched or pulled.
Sometimes when driving separately, the car will vibrate as soon as it meets a small barrier. One obvious feeling is whether the car is going to fall apart.
Noise problem The air operated butterfly valve makes an announcement noise during operation, which is caused by the collision between the air operated butterfly valve and the steel plate spring, frame or shaft, damage or falling of the rubber pad, deformation of the dust cylinder of the air operated butterfly valve, lack of oil and other reasons.
