搅拌车保养中容易出现哪些误区？

所属分类：公司新闻发布时间：2021-01-20 来源：浏览量：18

俗话说得好，混凝土搅拌车七分保养三份修。虽然搅拌车体型庞大，但是其内在的零部件是非常脆弱的，只有定期检查和保养，才能延长爱车的使用寿命。有些司机在搅拌车的日常保养中会出现一些操作不当的情况。

As the saying goes, the concrete mixer is maintained in seven parts and repaired in three parts. Although the mixer is huge, its internal parts are very fragile. Only regular inspection and maintenance can extend the service life of the mixer. Some drivers in the daily maintenance of mixer will appear some improper operation.

一、乱涂黄油

1、 Daub butter

搅拌车打黄油主要是起一个润滑的作用，一般搅拌车旋转、啮合等地方都需要黄油。有些维修工会在汽缸垫上也打上黄油，借此增强发动机的密封性。这种做法是错误的。气缸螺栓拧紧后，一部分黄油不可避免地会流入气缸，外面残余的黄油在高温下还会在缸垫、缸盖与机体平面之间形成缝隙，反而降低密封性。

The main purpose of beating butter on the mixer is to lubricate it. Generally, butter is needed in the rotation, meshing and other places of the mixer. Some maintenance workers also put butter on the cylinder gasket to enhance the tightness of the engine. This is wrong. After the cylinder bolts are tightened, part of the grease will inevitably flow into the cylinder, and the residual grease will form a gap between the cylinder gasket, cylinder head and the plane of the engine block at high temperature, which will reduce the sealing performance.

二、长时间不换机油

2、 Do not change the oil for a long time

更换机油是许多司机容易忽视的一点。如果长期只是一昧地添加机油，发动机的许多零部件会缺少润滑，长此以往磨损加剧。柴油机在运转的过程中也会吸附很多杂质进入机油，如果长期不更换机油，可能导致烧瓦、抱轴等问题。

Changing engine oil is a point that many drivers tend to ignore. If the engine oil is added blindly for a long time, many parts of the engine will be lack of lubrication, and the wear will increase in the long run. During the operation of diesel engine, a lot of impurities will be absorbed into the engine oil. If the engine oil is not changed for a long time, it may cause problems such as Bush burning and axle holding.

三、明火加温活塞

3、 Open flame heating piston

有经验的维修工都知道，在安装活塞销之前，要先让活塞受热膨胀。一些人为了省事，直接用明火对活塞进行加热。这种方式会让活塞受热不均产生变形，正确做法是讲活塞放入热油中均匀受热。

Experienced repairmen know that the piston should be heated and expanded before installing the piston pin. In order to save trouble, some people directly use open fire to heat the piston. The correct way is to put the piston into the hot oil and heat it evenly.

四、使用砂布打磨轴瓦

4、 Use emery cloth to grind the bearing bush

刮瓦技术难度较大，缺乏经验的维修工难以掌握，为此，有人在更换轴瓦时，为了增大轴瓦与曲轴的接触面积，就用砂布打磨代替刮瓦。这种方法会使砂布上较硬的颗粒嵌入轴瓦合金，柴油机运转过程中加速轴颈的磨损，缩短曲轴的使用寿命。

It is difficult for inexperienced maintenance workers to master the scraping technology. Therefore, when replacing the bearing bush, in order to increase the contact area between the bearing bush and the crankshaft, someone uses abrasive cloth to grind instead of scraping the bearing bush. This method will make the hard particles on the abrasive cloth embedded in the bearing bush alloy, accelerate the wear of the journal during the operation of the diesel engine, and shorten the service life of the crankshaft.
