How can I check whether my shock absorber fails?
In the past, pneumatic butterfly valves have become more and more common in life and consumption, and their applications are also very common. Then, pneumatic butterfly valves are mainly used to prevent the shock when the ball valve rebounds after shock absorption and the impact from the road surface. Pneumatic butterfly valves have a lot to do with warmth. So in ordinary daily maintenance, we often see that the shock absorber is invalid or not working well, At this time, we should learn some simple identification methods to determine whether they can be used. Today, the manufacturer of Dongfeng pneumatic butterfly valve will analyze the failure certification tips of pneumatic butterfly valve.
After confirming that there is a problem or failure of the shock absorber, check whether the pneumatic butterfly valve can leak oil or has traces of obsolete oil leakage. The oil seal washer and seal washer are broken, and the nuts of the oil storage cylinder cover are loose. The oil seal and sealing washer may be damaged and invalid, so the seal shall be replaced with a new one. If the oil leakage still cannot be eliminated, the shock absorber should be pulled out. If it feels stuck or different in weight, further check whether the clearance between the piston and the cylinder barrel is too large, whether the piston connecting rod of the shock absorber is bent, and whether the surface of the piston connecting rod and the cylinder barrel are scratched or pulled.?
