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:

如果自動攪拌車的減震器失效或者出現(xiàn)問題，應(yīng)查看減震器是否有漏油現(xiàn)象，用力按下保險杠，然后松開，假如自動攪拌車有兩到三次的騰躍，就說明減震器是好的。

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.

自動攪拌車減震器漏油一般是以下幾個原因：

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

1. 減震器內(nèi)部的清潔度不夠好，有焊渣、鐵屑等雜物導(dǎo)致油封磨損。

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. 減震器的工作條件比較惡劣，外部的泥沙等雜物進(jìn)入油封，導(dǎo)致其磨損漏油。

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. 減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. 可能是在噴底盤裝甲的時候，減震器沒有遮擋好，裝甲附在減震器活塞桿上導(dǎo)致油封磨損而漏油。

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. 控制活塞運(yùn)動的支桿需要在金屬管的一端延長出來，所以這個部位得密封嚴(yán)密，一般的漏油都和密封不嚴(yán)有直接關(guān)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. 一般自動攪拌車的液壓的減震器漏油就說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.

自動攪拌車在緩慢行駛中緊急制動，此時如果車輛的振動比較厲害，就說明減震器有問題，需要拆下減震器將其直立，并把下端銜接環(huán)夾在臺鉗上，用力拉壓減震桿數(shù)次，此時應(yīng)有穩(wěn)定的阻力，往上拉的阻力應(yīng)大于向下的阻力，如果阻力不穩(wěn)定或無阻力，可能是減震器內(nèi)部缺油或閥門零件損壞，應(yīng)終止修復(fù)或更換零件，并應(yīng)立即送去維修。

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.
