Four Ways to Teach You to Check the Working Performance of Automotive Pneumatic Ball Valves Skillfully
Four methods can teach you to check the working performance of the pneumatic ball valve of the car. For driving on rough roads, the pneumatic ball valve is very important. Automobile pneumatic ball valve is usually installed on the automobile suspension system. If the pneumatic ball valve cannot work normally, it will reduce the life of parts in various parts of the automobile, and also greatly reduce the stability of the automobile. People sitting in the car will also feel quite uncomfortable with the stability. Remind everyone to check whether the pneumatic ball valve can work properly before going out, especially when there are many uneven roads on a long journey.
The following is about how to check the working efficiency of pneumatic ball valves.
1. First, you can drive at a low speed and then brake hard. If you find that the car vibrates violently and the human body feels uncomfortable, then there is a problem with the pneumatic ball valve.
2. Press the bumper firmly, and then release it. If the car jumps 2-3 times, it indicates that the pneumatic ball valve works well.
3. 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, explain that there is no resistance inside the pneumatic ball valve, and the pneumatic ball valve does not work. At this time, take part in the appropriate lubricating oil, and then stop the test. If the shell is hot, the pneumatic ball valve is short of oil, and it should be filled with enough oil; Otherwise, the pneumatic ball valve is invalid.
4. Dismantle the pneumatic ball valve to make it upright, clamp the lower connecting ring on the bench clamp, and pull and press the shock absorber 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 damage of valve parts, and the repair or replacement of parts should be stopped.
Oil leakage is one of the reasons for abnormal operation of pneumatic ball valve. If the pneumatic ball valve is free of oil leakage, check whether the pneumatic ball valve joint pin, joint rod, joint hole, bushing, etc. are damaged, desoldered, cracked or scattered. If the above inspection is normal, the pneumatic ball valve shall be further synthesized to check whether the fit clearance between the piston and the cylinder barrel is too large, whether the cylinder barrel is strained, whether the valve seal is good, whether the valve clack fits tightly with the valve seat, and whether the extension ball valve of the pneumatic ball valve is too soft or broken. The method of grinding or replacing parts shall be adopted according to the condition.
If the problem that the pneumatic ball valve makes a noise is found, it is mainly caused by the collision between the pneumatic ball valve and the steel plate ball valve, the frame or the shaft, the damaged or scattered rubber gasket, the deformation of the dust cylinder of the pneumatic ball valve, and the lack of oil.
The above four methods can effectively test whether the pneumatic ball valve works normally. As for the first method, it is better to use less, because frequent emergency braking is likely to cause damage to the braking system. The second way is to introduce you to try the bumper method. It is convenient and effective. Before a long trip, check whether the pneumatic ball valve can leak oil. If it does, it will form the source of the problem of the pneumatic ball valve in the middle of the road.
