If the shock absorber of the mixer fails or has problems, you should first check whether the shock absorber has oil leakage, press the bumper hard, and then release it. If the mixer has two or three jumps, it means that the shock absorber is good. The mixer is in emergency braking when it is running slowly. At this time, if the vibration of the vehicle is severe, it means that there is something wrong with the shock absorber. It is necessary to remove the shock absorber, erect it, clamp the lower connecting ring on the vise, and pull and press the shock absorber rod several times. At this time, there should be stable resistance. The resistance of pulling up should be greater than that of pulling down. If the resistance is unstable or there is no resistance, it may be the shock absorber In case of internal oil shortage or valve parts damage, repair or replacement of parts shall be terminated and sent to repair immediately.
The reasons for oil leakage of mixer shock absorber are as follows:
1. The internal cleanliness of the shock absorber is not good enough, and there are welding slag, scrap iron and other debris, which lead to oil seal wear.
2. The working condition of the shock absorber is very bad, and the foreign matters such as sediment enter into the oil seal, resulting in wear and oil leakage.
3. The lip of the oil seal of the shock absorber is aging, and the sealing function is lost.
4. When spraying chassis armor, the shock absorber was not covered well, and the armor was attached to the shock absorber piston rod, causing oil seal wear and leakage.
5. The supporting rod to control the movement of the piston needs to be extended at one end of the metal tube, so this part must be tightly sealed. Generally, the leakage is directly related to the poor sealing.
6. The oil leakage of the hydraulic shock absorber of the general mixer indicates that its service life has come.
