Today, we share several maintenance techniques of rubber shock absorber
. For shock absorber, rubber shock absorber and spring shock absorber are popular shock absorbers at present. Because these two kinds of shock absorbers are used more frequently, we should pay attention to maintenance at many times. Shock absorbers are very wearable parts in daily use. Whether rubber shock absorbers or spring shock absorbers are good or bad, they will directly affect the driving stability of automobiles and the life of other parts.
Therefore, we should regularly maintain and inspect the shock absorbers
. Some points for attention in the use of shock absorbers are as follows:
1. Press the shock absorber forcefully and the shock absorber will jump 2-3 times, which indicates that the shock absorber works well.
2. Remove the shock absorber and erect it. Clamp the lower end connecting ring on the bench clamp. Pull the shock absorber rod forcefully several times. At this time, there should be stable resistance. The resistance to pull up should be greater than that to press down. If the resistance is unstable or no resistance, it may be lack of oil inside the shock absorber or damage to the valve parts, the parts should be repaired or replaced.
3. When using the shock absorber under poor working conditions and touching the shell of the shock absorber by hand, it is obvious that the heat of the machine is not enough, which indicates that there is no resistance inside the shock absorber and that the shock absorber is not working. At this time, proper lubricating oil should be added in time, and then the test should be carried out. If the phenomenon of heat of the machine indicates that the machine is normal, otherwise, it indicates that there is a mechanical failure.
Finally, after confirming that the rubber shock absorber or spring shock absorber can not be used normally or fail, we should pay attention to check whether the shock absorber has oil leakage or traces of obsolete oil leakage, oil seal gasket, seal gasket rupture damage, loosening of oil cylinder head nuts, and so on. When similar situations occur, we should timely replace and repair them.
