搖臂和發(fā)動機是攪拌車的重要組成部分，在拆卸和安裝搖臂時，應(yīng)從五個方面檢查搖臂總成，下面讓我們一起來看看怎么回事吧。

The rocker arm and engine are important components of the mixer. When removing and installing the rocker arm, we should check the rocker arm assembly from five aspects. Let's see what happened next.

檢查搖臂球面接觸部位的磨損情況。如果有輕微的磨損槽，可以用油石或研磨機進行研磨。如果磨損嚴(yán)重，應(yīng)更換搖臂。

Check the wear of the spherical contact part of the rocker arm. If there is a slight wear groove, you can grind it with an oilstone or a grinder. If the wear is serious, replace the rocker arm.

對于帶氣門間隙調(diào)整螺釘?shù)膿u臂，應(yīng)檢查搖臂上的調(diào)整螺釘、鎖緊螺母和螺孔是否完好，如有損壞應(yīng)更換。

For rocker arms with valve clearance adjustment screws, check whether the adjustment screws, lock nuts and screw holes on the rocker arms are intact, and replace them if damaged.

對于帶有滾動軸承的浮動搖臂，應(yīng)檢查其軸承，如果嚴(yán)重磨損或損壞，應(yīng)更換搖臂。

For floating rocker arms with rolling bearings, check their bearings. If they are seriously worn or damaged, replace the rocker arms.

安裝在搖臂軸上的搖臂，測量搖臂襯套內(nèi)徑和搖臂軸外徑，檢查配合間隙，維修超過允許限度時更換零件或總成。

For the rocker arm installed on the rocker arm shaft, measure the inner diameter of the rocker arm bushing and the outer diameter of the rocker arm shaft, check the fit clearance, and replace the parts or assemblies when the maintenance exceeds the allowable limit.

檢查搖臂是否完全變形。如果超過允許極限，則糾正或更換搖臂軸。

Check whether the rocker arm is completely deformed. If the allowable limit is exceeded, correct or replace the rocker shaft.

水泥攪拌車如何檢查發(fā)動機預(yù)熱

How to check engine preheating of cement mixer

發(fā)動機預(yù)熱前的檢查：檢查液壓油的存儲量，檢查減速器的潤滑油有無泄露，檢查液壓系統(tǒng)的液壓油有無泄露，各接頭部位是否有滲漏現(xiàn)象，檢查操縱裝置的操縱手柄是否置于停止位置，檢查各連接緊固件不能有松動現(xiàn)象。

Inspection before engine preheating: check the storage capacity of hydraulic oil, check whether the lubricating oil of reducer leaks, check whether the hydraulic oil of hydraulic system leaks, check whether there is leakage at all joints, check whether the joystick of the control device is placed in the stop position, and check whether all connecting fasteners are not loose.

發(fā)動機預(yù)熱時的檢查部位：檢查油泵有無異常聲音，檢查液壓馬達有無異常聲音，檢查減速器有無異常聲音，查水泵是否正常轉(zhuǎn)動，檢查混凝土攪拌車攪拌筒的進料回轉(zhuǎn)是否正常，能否進行正常的工作回轉(zhuǎn)。

Inspection parts during engine preheating: check whether the oil pump has abnormal sound, whether the hydraulic motor has abnormal sound, whether the reducer has abnormal sound, whether the water pump rotates normally, whether the feeding rotation of the mixing drum of the concrete mixer truck is normal, and whether the normal working rotation can be carried out.

攪拌車各連接螺栓的擰緊力矩檢查：副車架與主車副梁的連接、減速機與罐體等采用高強度螺栓，需要定期擰緊。時間不能超過兩個月，是不同螺栓的擰緊力矩值。

Tightening torque inspection of connecting bolts of mixer truck: high strength bolts are used for the connection between subframe and auxiliary beam of main truck, reducer and tank body, which need to be tightened regularly. The time shall not exceed two months, which is the tightening torque value of different bolts.
