Performance test of pneumatic ball valve?
The quality of the pneumatic ball valve will affect the stability of the vehicle and the service life of other parts. Therefore, the automobile pneumatic ball valve needs to be in a good working condition for a long time. What kind of pneumatic ball valve is good! We checked it together!
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. Press the bumper firmly and then release it. If the car jumps 2-3 times, the pneumatic ball valve works well. Dismantle the pneumatic ball valve to make it stand upright, clamp the lower connecting ring on the bench clamp, and pull and press the valve rod several times with force. At this time, there should be stable resistance. The resistance of pulling upward should be greater than the resistance of pressing downward. If the resistance is unstable or no resistance, it may be the lack of oil inside the pneumatic ball valve or the valve parts are damaged, and the repair or replacement of parts should be stopped. These three points are often used in the process of inspection!
