How does the tutor from the electric butterfly valve factory check the defects of the electric butterfly valve?
Auto electric butterfly valve has the function of alleviating the impact of the road on the car and quickly absorbing the vibration generated when it is stable. Do you know how to stop the inspection of auto electric butterfly valve and what operating skills are there? Now let's see the sharing content of Dongfeng Xizhen electric butterfly valve:? Method 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, you can participate in the appropriate lubricating oil and then stop the test. If the shell is hot, the electric butterfly valve is short of oil, and you should add enough oil; Otherwise, the electric butterfly valve is invalid.
Method 2: Press the bumper firmly, and then release it. If the car jumps 2 to 3 times, it means that the electric butterfly 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, it means that the electric butterfly valve is not working properly.
Method 4.
After confirming that the electric butterfly valve has a problem or failure, the first thing to check is whether the electric butterfly valve has oil leakage or traces 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, the electric butterfly valve should be pulled out. 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 electric butterfly valve is bent, and whether the surface of the piston connecting rod and the cylinder barrel are scratched or pulled. Finally, the electric butterfly valve will make a noise in the theoretical application, which is mainly caused by the collision between the electric butterfly valve and the steel plate butterfly valve, the frame or the shaft. If the rubber gasket is damaged or scattered, the dust cylinder of the electric butterfly valve is deformed, and there is a lack of oil, etc., the cause should be found out and repaired. The normal operation of the electric butterfly valve can ensure that we can travel more smoothly during driving, so it is necessary to check whether the electric butterfly valve works normally in time.
