概述:有很多驾驶自动上料搅拌车的司机师傅们,行车前会对车辆进行检查,这是一个非常好的习惯,我们要在行车前做三项检查,是哪三项呢?
有很多驾驶自动上料搅拌车的司机师傅们,行车前会对车辆进行检查,这是一个非常好的习惯,我们要在行车前做三项检查,是哪三项呢?
There are a lot of drivers who drive the automatic feeding mixer. They will check the vehicle before driving. This is a very good habit. We should do three inspections before driving. Which are the three?
(1)发动机预热时的检查部位:检查油泵有无异常声音;检查液压马达有无异常声音;检查减速器有无异常声音;检查水泵是否正常转动;检查搅拌筒的进料回转是否正常,能否进行正常的工作回转。
(1) Inspection parts during engine preheating: check whether the oil pump has abnormal sound; check whether the hydraulic motor has abnormal sound; check whether the reducer has abnormal sound; check whether the water pump rotates normally; check whether the feeding rotation of the mixing drum is normal and whether the normal working rotation can be carried out.
(2)检查辅助卸料槽的锁扣、卸料槽的锁柄、防转手柄是否锁紧。
(2) Check whether the lock catch of auxiliary discharge chute, lock handle of discharge chute and anti rotation handle are locked.
(3)发动机预热前的检查:检查液压油的存储量。(检查油位的存储器);检查减速器的润滑油有无泄露;检查液压系统的液压油有无泄露,各接头部位是否有渗漏现象;检查操纵装置的操纵手柄是否置于停止位置;检查各连接紧固件不能有松动现象。
(3) Check before engine preheating: check the storage of hydraulic oil. (check the oil level memory); check whether the lubricating oil of the reducer leaks; check whether the hydraulic oil of the hydraulic system leaks and whether there is leakage at the joints; check whether the control handle of the control device is at the stop position; check that the connecting fasteners are not loose.

自动上料搅拌车有液压三大件分别是:变量泵、马达、减速机,这三件每一种的维护与保养都是非常重要的,今天我们看一下减速机的维护与保养。
The automatic feeding mixer has three hydraulic parts: variable pump, motor and reducer. Each of these three parts is very important. Today, let's take a look at the maintenance of the reducer.
一、建议在油温为60℃左右放油;每次换油完毕,需检查连接螺栓的紧固情况;检查结束,需要用扭矩扳手重新紧固一下所有与变速箱连接的螺栓;每月需检查一次油位。注意:分体减速机匹配的泵、马达中的油品为46号抗磨液压油。
1、 It is recommended to drain the oil at the oil temperature of about 60 ℃; after each oil change, check the fastening condition of the connecting bolts; after the inspection, re tighten all the bolts connected with the gearbox with a torque wrench; check the oil level once a month. Note: the oil in the pump and motor matched with split reducer is 46 anti-wear hydraulic oil.
二、发动机转速不允许过高,转速由慢到快应慢慢增加,启动前2min搅拌筒转速不宜超过18r/min,对带水泵取力口的减速机初次运行转速不宜超过15r/min,因为发动机转速过高会损坏变速箱。
2、 The engine speed is not allowed to be too high, and the speed should be increased slowly from slow to fast. The speed of mixing drum should not exceed 18r / min 2 minutes before starting. The speed of reducer with water pump power take-off should not exceed 15R / min for the first time, because too high engine speed will damage the gearbox.
三、按不同的使用期限,应对减速机做以下例行保养:
3、 According to different service life, the following routine maintenance should be done for the reducer:
油品: P3301、P4300等分体减速机使用的齿轮油型号为:SAE 80W-90/SAE85W-90;API GL-5级;
Oil: the gear oil used in p3301, p4300 and other split reducers is SAE 80w-90 / sae85w-90; API GL-5 grade;

变量泵、马达换油:第一次换油时间为新车首次使用500个工作小时,同时更换原装专用滤油器;第二次换油时间为车辆再次工作2000个工作小时后,同时更换专用滤油器;以后为每2000个工作小时或一年,只要满一年不管工作了多少个小时,必须换油,同时更换专用滤油器;换油时系统管路切勿打开,只需将油箱的油放干净,同时也可以打开泵、马达壳体泄油口放油,然后将新的油品倒入油箱中,加油时要注意排空系统中的空气;不同品牌的油严禁混用。
Oil change of variable displacement pump and motor: the first oil change time is 500 working hours after the new vehicle is used for the first time, and the original special oil filter is replaced at the same time; the second oil change time is to replace the special oil filter at the same time after the vehicle works for 2000 working hours again; After 2000 working hours or a year, the oil must be changed and the special oil filter must be replaced no matter how many hours have been worked. When changing the oil, the system pipeline should not be opened, only the oil in the oil tank should be drained. At the same time, the oil drain port of the pump and motor shell can be opened to drain the oil, and then the new oil is poured into the oil tank. Pay attention to emptying the air in the system when refueling; It is forbidden to mix different brands of oil.
