How to troubleshoot the defects of automobile pneumatic ball valve?
The automobile pneumatic ball valve has the function of alleviating the impact of the road on the automobile and quickly absorbing the vibration generated when it is stable. Do you know how to stop the inspection of the automobile pneumatic ball valve and what operating skills are there? Now let's see the sharing content of Dongfeng Xizhen pneumatic ball valve:? Method 1: Stop the car after driving 10km on the road with poor road conditions, touch the shell of the pneumatic ball valve with your hand. If it is not hot enough, it means that there is no resistance inside the pneumatic ball valve, and the pneumatic ball valve does not work. At this time, you can participate in the appropriate lubricating oil and then stop the test. If the shell is hot, the pneumatic ball valve is short of oil inside, and you should add enough oil; Otherwise, the pneumatic ball valve is invalid.
Method 2: Press the bumper firmly, and then release it. If the car jumps for 2 to 3 times, it means that the pneumatic ball valve works well, otherwise it is not working well.
Method 3: When the car is running slowly and emergency braking occurs, if the car vibrates violently, the pneumatic ball valve does not work properly.
Method 4.
After confirming that there is a problem or failure of the pneumatic ball valve, the first thing to check is whether the pneumatic ball valve has oil leakage or signs or phenomena 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, pull out the pneumatic ball valve. If the weight is different, 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. Finally, the pneumatic ball valve will make a noise in the theoretical application, which is mainly caused by the collision between the pneumatic ball valve and the steel plate ball valve, the frame or the shaft. If the rubber gasket is damaged or scattered, the dust cylinder of the pneumatic ball valve is deformed, and the oil is lacking, the reason should be found out and repaired. The normal operation of the pneumatic ball valve can ensure that we can travel more smoothly when driving, so it is necessary to timely check whether the pneumatic ball valve works normally.
