Electric Butterfly Valve Co., Ltd. introduces you to the maintenance of electric butterfly valve?
Electric Butterfly Valve Co., Ltd. will introduce you to the maintenance of electric butterfly valves. The main items are as follows. Let's get to know:
1. Dismantle the shock absorber and erect it, clamp the lower connecting ring on the bench clamp, 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 due to lack of oil in the shock absorber or damage of valve parts, and the repair or replacement of parts should be stopped.
2. If the car vibrates violently when the car drives slowly and brakes in an emergency, it indicates that there is a problem with the shock absorber??
3. Stop the car after driving 10km on the road with poor road conditions, touch the shock absorber housing with your hand. If it is not hot enough, it means that there is no resistance inside the shock absorber and the shock absorber does not work. At this time, you can participate in the appropriate lubricating oil, and then stop the test. If the shell is hot, it means that there is a lack of oil inside the shock absorber, and you should add enough oil; Otherwise, the shock absorber is invalid.
4. Press the bumper firmly, and then release it. If the car jumps for 2-3 times, it means that the shock absorber works well?
