The air butterfly valve products of Shanghai Dongfeng Pump Valve Factory are mainly used on the bases of buses, luxury cars, trucks, commercial vehicles, rail cars, industrial machinery, industrial equipment, etc. Dongfeng welcomes new and old customers to call: 021-6344211. Automobile air butterfly valve electric butterfly valve can rapidly attenuate the vibration of the frame and body when the vehicle is running, and improve the smoothness and comfort of the vehicle. In short, it is used to absorb the vibration force and stabilize the car body. The butterfly valve is used to maintain the height of the car body and play a buffering role in case of turbulence. But wouldn't it be more comfortable if there were only butterfly valves? Not at all. If there is only a butterfly valve, the vehicle body will bounce up and down like a butterfly valve toy after bumping, so the damping cylinder must be used to control the compression and rebound effect of the butterfly valve.
Therefore, the coordination of butterfly valve and damping cylinder can determine the hardness of a vehicle's valve; The control balance of comfort and movement is the difficulty of electric butterfly valve tuning. The electronic adjustable damping valve is usually used on luxury models, so that the suspension hardness can be adjusted at any time according to the different road surfaces. Car enthusiasts who are obsessed with sports driving will modify their own valve system to make the car lower and harder and further improve the handling.
The automobile electric butterfly valve will make a noise in actual use, which is mainly caused by the collision between the electric butterfly valve and the steel plate butterfly valve, the frame or the shaft, the damage or falling of the rubber pad, the deformation of the dust cylinder of the electric butterfly valve, the lack of oil and other reasons. The causes should be found out and repaired. Next, Dongfeng will introduce some common questions about automobile electric butterfly valve!
1、 Why should automobile electric butterfly valve be maintained?
Whether the automobile air butterfly valve is a vulnerable part depends on the road conditions. If the electric butterfly valve is driven with frequent bumps, it will stretch at a high frequency, and the oil temperature in the electric butterfly valve will gradually rise, which is not conducive to the long-term use of the electric butterfly valve.
The operation of the electric butterfly valve will directly affect the stability of the vehicle and the life of other parts, or the oil seal washer, the seal washer is broken, the nut of the oil storage cylinder cover is loose, or there is a collision between the electric butterfly valve and the steel plate butterfly valve, the frame or the shaft, or there is a sign of oil leakage. In case of oil leakage, it is undoubtedly very dangerous.
Therefore, we should keep the electric butterfly valve in good working condition. Regular inspection and maintenance is a detail control problem.
2、 What symptoms will appear if the electric butterfly valve of the car is broken?
1. Stop the car after driving 10 km 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 heated, it means that the electric butterfly valve is lack of oil inside, and it should be filled with enough oil, otherwise, it means that the electric butterfly valve is invalid.
2. Press the bumper firmly and release it. If the car jumps no more than once or twice, the electric butterfly valve works well. If you keep nodding and bowing up and down and look very elastic, it will be broken.
3. When the car drives slowly and brakes urgently, if the car vibrates violently, it indicates that there is a problem with the electric butterfly valve.
4. Dismantle the electric butterfly valve to make it 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 to recover should be greater than the resistance of pressing downward. If the resistance is unstable or there is no resistance, it may be that the electric butterfly valve is lack of oil or the valve parts are damaged, and the parts should be repaired or replaced.
3、 How much does it cost to change the air suspension airbag?
1. The double cylinder inflatable electric butterfly valve for ordinary cars is generally 100-200 yuan, and that for minicars is about 100 yuan, or even lower. In addition, the front electric butterfly valve is usually cheaper than the rear electric butterfly valve. For example, the factory price of a set of electric butterfly valves for the Corolla car produced by FAW Toyota is about 700 yuan.
2. The SP parts sold to us by the automobile factory will naturally be higher than the ex factory price, which is also a big part of the profit source of the automobile factory. For example, in the 4S store, the price of an Audi A6 electric butterfly valve is nearly 2000 yuan, and the original accessory is Monroe, Belgium. Of course, you can also change to another manufacturer, and the price will be much cheaper, such as FAW East Machinists.
3. The price of electric butterfly valves of different varieties is also different. Crown uses a single cylinder inflatable electric butterfly valve, whose price is higher than the ordinary double cylinder inflatable electric butterfly valve. Some C-class cars also use adjustable damping force electric butterfly valves, electromagnetic electric butterfly valves, etc., which will cost more.
4、 Under what circumstances does the automobile need to replace the electric butterfly valve?
Generally speaking, the electric butterfly valve should be replaced in case of noise, hardness, softness and oil leakage. However, when the above problems are found, do not judge the replacement of the electric butterfly valve too early. If there is a noise, check whether the installation is correct; If it is too hard or too soft, check whether there is any problem with the butterfly valve and the fixed connection electric butterfly valve; If oil leaks, check whether the cylinder cover is fastened.
The manufacturer of Dongfeng electric butterfly valve reminds everyone that the electric butterfly valve will make a noise in actual use, which is mainly caused by the collision between the electric butterfly valve and the steel plate butterfly valve, the frame or the shaft, the damage or falling of the rubber pad, the deformation of the dust-proof cylinder of the electric butterfly valve, the lack of oil and other reasons. Find out the causes and repair them.
