搅拌车颐养中轻易呈现哪些误区?

所属分类:公司消息 宣布时候:2021-01-20 来历:众富购彩:http://vncarmart.net 阅读量:18

俗语说得好,混凝土搅拌车七分颐养三份修。固然搅拌车体型复杂,可是其内涵的零部件长短常懦弱的,只要按期查抄和颐养,能力耽误爱车的利用寿命。有些司机在搅拌车的平常颐养中会呈现一些操纵不妥的环境。
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
搅拌车打黄油首要是起一个光滑的感化,普通搅拌车扭转、啮合等处所都须要黄油。有些维修工会在汽缸垫上也打上黄油,借此加强发念头的密封性。这类做法是毛病的。气缸螺栓拧紧后,一局部黄油不可防止地会流入气缸,里面剩余的黄油在低温下还会在缸垫、缸盖与机体立体之间构成裂缝,反而下降密封性。
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、长时候不换机油
2、 Do not change the oil for a long time
改换机油是良多司机轻易轻忽的一点。若是持久只是一昧地增加机油,发念头的良多零部件会贫乏光滑,久而久之磨损加重。柴油机在运行的进程中也会吸附良多杂质进入机油,若是持久不改换机油,能够致使烧瓦、抱轴等题目。
主动上料搅拌机
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
有经历的维修工都晓得,在装置活塞销之前,要先让活塞受热收缩。一些报酬了费事,间接用明火对活塞停止加热。这类体例会让活塞受热不均发生变形,准确做法是讲活塞放入热油中平均受热。
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、利用砂布打磨轴瓦
4、 Use emery cloth to grind the bearing bush
刮瓦手艺难度较大,缺少经历的维修工难以把握,为此,有人在改换轴瓦时,为了增大轴瓦与曲轴的打仗面积,就用砂布打磨取代刮瓦。这类体例会使砂布上较硬的颗粒嵌入轴瓦合金,柴油机运行进程中加快轴颈的磨损,延长曲轴的利用寿命。
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.
