有一句话说的好，小型搅拌车七分保养三分修，虽然小型搅拌车体型还是挺大的，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，不知您中招了吗？

There is a saying that small mixers require seven points of maintenance and three points of repair. Although small mixers are still very large, their internal parts are very fragile. Only regular inspection and maintenance can extend the service life of your car. Some drivers may operate improperly during the daily maintenance of the mixer truck. Do you win the bidding?

1，使用砂布打磨轴瓦

1. Grind the bearing bush with abrasive cloth

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，为了扩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。

The scraping technology is difficult for inexperienced maintenance workers to master. For this reason, some people use abrasive cloth to replace the scraping in order to expand the contact area between the bearing bush and the crankshaft when replacing the bearing bush. This method will make the hard particles on the abrasive cloth embedded in the bearing alloy, accelerate the wear of the journal during the operation of the diesel engine, and shorten the service life of the crankshaft.

2，明火加温活塞

2. 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 maintenance workers know that before installing the piston pin, the piston should be heated and expanded. In order to save time, some people directly heat the piston with open fire. In this way, the piston will be deformed due to uneven heating. The correct way is to put the piston into the hot oil for uniform heating.

3，长时间不换机油

3. 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 the oil is a point that many drivers tend to overlook. If you only add oil blindly for a long time, many parts of the engine will lack lubrication, and wear will increase in the long run. During the operation of the diesel engine, many impurities will also be absorbed into the engine oil. If the engine oil is not changed for a long time, it may cause problems such as burning of the bearing and holding of the shaft.
