Four Ways to Teach You to Check the Working Performance of Automobile Electric Butterfly Valves Skillfully
Four methods can teach you to check the working performance of the electric butterfly valve of the car. For driving on rough roads, the electric butterfly valve is very important. The electric butterfly valve is usually installed on the vehicle suspension system. If the electric butterfly valve cannot work normally, it will reduce the life of the parts in the vehicle and greatly reduce the stability of the vehicle. People sitting in the vehicle will also feel uncomfortable about the stability. Remind everyone to check whether the electric butterfly 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 the electric butterfly valve.
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 electric butterfly valve.
2. Press the bumper firmly, and then release it. If the car jumps 2-3 times, it indicates that the electric butterfly valve works well.
3. Stop the car after driving 10km on the road with poor road conditions, touch the shell of the electric butterfly valve with your hand. If it is not hot enough, explain that there is no resistance inside the electric butterfly valve, and the electric butterfly 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 electric butterfly valve is short of oil, and it should be filled with enough oil; Otherwise, the electric butterfly valve is invalid.
4. Dismantle the electric butterfly 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 electric butterfly 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 the abnormal operation of the electric butterfly valve. If there is no oil leakage from the electric butterfly valve, check whether the electric butterfly valve connecting pin, connecting rod, connecting hole, bushing, etc. are damaged, desoldered, cracked or scattered. If the above inspection is normal, the electric butterfly 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 stretch butterfly valve of the electric butterfly valve is too soft or broken. According to the condition, the method of grinding or replacing parts shall be adopted for repair.
If the problem that the electric butterfly valve makes a noise is found, it is mainly caused by the collision between the electric butterfly valve and the steel plate butterfly valve, the frame or the shaft, the damaged or scattered rubber gasket, the deformation of the dust cylinder of the electric butterfly valve, and the lack of oil.
The above four methods can effectively test whether the electric butterfly 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-distance trip, check whether the electric butterfly valve can leak oil. If it does, it will form the source of the fault of the electric butterfly valve in the halfway.
