What if the oil leakage can't be eliminated?
It is very simple. The pneumatic ball 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 ball 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.
The sound problem of the pneumatic ball valve is that it makes an announcement during operation, because the pneumatic ball valve collides with the steel plate spring, frame or shaft, the rubber pad is damaged or dropped, the dust cylinder of the pneumatic ball valve is deformed, and there is a lack of oil.
