自进料混凝土搅拌车必须要好好保养

自进料混凝土搅拌车这个大家伙不是家用车,但是养车依然是非常重要的,而且和家用车一样如果保养不当,可能非但起不到保养作用,反而会影响正常的工作,下面小编就给大家讲一下保养中经常遇到的4个误区:
The self feeding concrete mixer truck is not a household car, but car maintenance is still very important. Like household cars, if it is not properly maintained, it may not play a role in maintenance, but will affect normal work. The following small series will tell you about the four misunderstandings often encountered in maintenance:
乱涂黄油黄油是维护保养中最常用的润滑脂,但是只适合于一些齿轮部件,比如搅拌筒旋转和托轮部分。有一些维修工会在发动机汽缸垫上打黄油,说是可以增强发动机气密性,其实这是错误的,当气钢螺栓拧紧后,肯定会有一部分黄油进入汽缸内部,发动机运作时的高温会使这些黄油在缸垫、缸盖和气缸平面间形成缝隙,反而会降低气密性。
Scribbling butter is the most commonly used grease in maintenance, but it is only suitable for some gear parts, such as mixing drum rotation and supporting wheel. Some maintenance unions put butter on the engine cylinder gasket, saying that it can enhance the air tightness of the engine. In fact, this is wrong. When the gas steel bolts are tightened, some butter will certainly enter the cylinder. The high temperature during engine operation will make these butter form a gap between the cylinder gasket, cylinder head and cylinder plane, which will reduce the air tightness.
不换机油有一些司机没有更换机油的习惯,一是懒的换,二是只加不换。不管是柴油机还是汽油机,在运转过程中不可避免的会吸入很多杂质,机油的功能一是保证发动机内部的润滑,二是通过不停的运转,将这些杂质从发动机内部带出,长期不换机油,这些杂质堆积在机油箱内,就起不到清洁发动机的作用,可能会导致烧瓦、抱轴等问题。
Some drivers don't have the habit of changing the oil. First, they change it lazily, and second, they only add it without changing it. Whether diesel engine or gasoline engine, it is inevitable to inhale a lot of impurities during operation. The function of engine oil is to ensure the lubrication inside the engine, and to bring these impurities out of the engine through continuous operation. If the engine oil is not changed for a long time, these impurities accumulate in the engine oil tank, they will not play the role of cleaning the engine, which may lead to tile burning Axle holding and other problems.

明火加温活塞安装活塞销之前都需要先加热活塞,使其受热膨胀,正确的加热方法应该是将活塞放入热油中均匀受热,但是有一些维修人员为了省事儿,直接用明火加热活塞,这样会使活塞受热不均发生变形,一定要注意。
Before installing the piston pin, it is necessary to heat the piston to make it expand. The correct heating method should be to put the piston into hot oil and heat it evenly. However, some maintenance personnel directly heat the piston with open fire in order to save trouble, which will cause uneven heating and deformation of the piston. We must pay attention to it.
用砂纸打磨轴瓦刮瓦的技术难度比较大,缺乏经验的维修工很难掌握,所以为了增大轴瓦和曲轴的接触面积,有一些维护人员在更换轴瓦时,不刮瓦而是用砂纸打磨,这种方法会使砂纸上个颗粒嵌入轴瓦合金,在柴油机运转过程中磨损轴颈,导致曲轴的使用寿命缩短。
It is difficult to polish and scrape the bearing bush with sandpaper, which is difficult for inexperienced maintenance workers to master. Therefore, in order to increase the contact area between the bearing bush and the crankshaft, some maintenance personnel polish the bearing bush with sandpaper instead of scraping the bush. This method will make a particle on the sandpaper embedded in the bearing bush alloy and wear the journal during the operation of the diesel engine, As a result, the service life of the crankshaft is shortened.
