There are also many parts on the chassis of the automatic mixer. Shock absorber is a part that everyone should be familiar with. The shock absorber is used for the spring to absorb the vibration and the impact from the road surface. In the process of the automatic mixer, the shock absorber usually makes a noise, which is caused by the collision between the shock absorber and leaf spring, frame or shaft, damage of rubber pad, deformation of shock absorber dust cylinder and lack of oil. How to judge whether the shock absorber is in good condition? The following small series for you to introduce how to maintain the shock absorber of automatic mixer:

如果自动搅拌车的减震器失效或者出现问题，应查看减震器是否有漏油现象，用力按下保险杠，然后松开，假如自动搅拌车有两到三次的腾跃，就说明减震器是好的。

If the shock absorber of the automatic mixer fails or has problems, you should first check whether the shock absorber has oil leakage, press the bumper firmly, and then release it. If the automatic mixer has two or three jumps, it shows that the shock absorber is good.

自动搅拌车减震器漏油一般是以下几个原因：

Oil leakage of shock absorber of automatic mixer truck is generally caused by the following reasons:

1. 减震器内部的清洁度不够好，有焊渣、铁屑等杂物导致油封磨损。

1. The internal cleanliness of the shock absorber is not good enough, and there are welding slag, iron chips and other debris causing oil seal wear.

2. 减震器的工作条件比较恶劣，外部的泥沙等杂物进入油封，导致其磨损漏油。

2. The working conditions of the shock absorber are relatively bad, and the external sand and other debris enter the oil seal, causing its wear and oil leakage.

3. 减震器油封的唇口老化，失去了密封的功能。

3. The lip of shock absorber oil seal is aged and lost its sealing function.

4. 可能是在喷底盘装甲的时候，减震器没有遮挡好，装甲附在减震器活塞杆上导致油封磨损而漏油。

4. It may be that when spraying the chassis armor, the shock absorber is not well covered, and the armor is attached to the shock absorber piston rod, resulting in oil seal wear and oil leakage.

5. 控制活塞运动的支杆需要在金属管的一端延长出来，所以这个部位得密封严密，一般的漏油都和密封不严有直接关系的。

5. The supporting rod controlling the piston movement needs to be extended at one end of the metal tube, so this part must be sealed tightly. The general oil leakage is directly related to the loose sealing.

6. 一般自动搅拌车的液压的减震器漏油就说明它的使用年限已到。

6. The oil leakage of hydraulic shock absorber of automatic mixer truck indicates that its service life is up.

自动搅拌车在缓慢行驶中紧急制动，此时如果车辆的振动比较厉害，就说明减震器有问题，需要拆下减震器将其直立，并把下端衔接环夹在台钳上，用力拉压减震杆数次，此时应有稳定的阻力，往上拉的阻力应大于向下的阻力，如果阻力不稳定或无阻力，可能是减震器内部缺油或阀门零件损坏，应终止修复或更换零件，并应立即送去维修。

When the automatic mixer truck is running slowly, emergency braking is required. If the vibration of the vehicle is severe, it indicates that there is something wrong with the shock absorber. It is necessary to remove the shock absorber and put it upright. Clamp the lower end connecting ring on the vise, and pull and press the shock absorber rod several times. At this time, there should be stable resistance, and the resistance upward should be greater than the downward resistance. If the resistance is unstable or there is no resistance, it may be reduced If there is no oil in the vibrator or the valve parts are damaged, the repair or replacement of the parts should be stopped and sent for repair immediately.
