Solution to problems of electric butterfly valve
1. 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, it means that there is no resistance inside the electric butterfly valve, and the electric butterfly valve does not work. At this time, appropriate lubricating oil can be added and the test can be carried out again. If the shell is hot, it means that the electric butterfly valve is lack of oil inside, and it should be filled with enough oil; Otherwise, the electric butterfly valve is invalid.
2. Press the bumper firmly, and then release it. If the car jumps 2-3 times, the electric butterfly valve works well. When the car is running slowly and emergency braking occurs, if the car vibrates violently, it indicates that there is a problem with the electric butterfly valve.
3. Dismantle the electric butterfly valve to make it stand upright, clamp the lower connecting ring on the bench clamp, and pull and press the shock absorber rod several times. 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 parts should be repaired or replaced.
