挖掘机运用中的有数的不良陈规?

一、水箱开锅加冷水
First, water tank opening and cold water
在挖掘机倡议机超负荷作业、散热不好等环境都市构成水箱开锅的外形。很多缝补工的应声是加水。但是,要是这个时间加冷水就会构成缸盖和缸体炸裂,以是这个时间应该先抑制倡议机,等其自然冷却之后在举行加水。
The overload of the excavator engine and the bad heat dissipation will cause the water tank to boil. The first reaction of many repairmen is to add water. However, if this time adding cold water will cause the cylinder head and cylinder to blow up, so the engine should be stopped at this time, and water will be added after its natural cooling.
二、从不换机油
Two. Never change the oil
挖掘机机油在挖掘机当中的作用尤为庞大,很多缝补工对此都很重视。他们完全依据范例要求举行添加。但是,很多的缝补工却遗忘了对机油质量查抄和蜕变机油的互换。暂时的只是添加而不互换机油,就会使得倡议机的很多部件在润滑较差的环境下变乱,所构成的磨损远超正常外形。并且,柴油机在运转的进程当中,很多的污物也会进入到机油当中,要是活期不互换机油,很容易引发热瓦、抱轴等不测变乱。
The oil of excavator is especially important in the excavator. Many repairmen pay much attention to it. They are added completely according to the standard requirements. But many repairmen forgot about the oil quality check and the replacement of the oil. For a long time, only adding but not changing the oil will cause many parts of the engine to work in a poor lubrication environment, resulting in much more wear and tear than normal. Moreover, in the process of diesel engine operation, a lot of dirt will also enter the oil. If the oil is not replaced regularly, it is easy to cause accidents such as burning and holding shaft.
三、黄油胡乱涂抹
Three. Daub with butter
挖掘机黄油其紧张地作用是润滑与密封。以是,偶然偶然缝补工在维修进程当中,就会在其汽缸垫上涂抹上黄油,以为多么子就可以增长其柴油倡议机的密封遵从。可是,这种做法确实是大错特错的。由于,要是在汽缸垫上涂抹了黄油,当汽缸螺栓拧紧时,一定会有一局部黄油流入到气缸当中。剩下的在外部的黄油在遭到高温影响之后还会构成缸垫、缸盖与机体平面之间发生一定的弊端,多么反倒是飞扬了缸垫原本的密封性。
The main function of the excavator butter is to lubricate and seal. Therefore, sometimes the repairman will apply butter on its cylinder pad during the maintenance process, which will increase the sealing performance of its diesel engine. But this is really a mistake. Because if butter is applied to the cylinder gasket, some of the butter will flow into the cylinder when the cylinder bolts are tightened. The remaining outside butter will cause a certain gap between the cylinder pad, the cylinder head and the plane of the body after being affected by the high temperature. In this way, the original seal of the cylinder pad is reduced.
四、缸套和活塞南方双彩网产品不举行组合即陈设

Four, cylinder liner and piston products are not assembled or installed.
很多缝补工在维修的时间,以为新品都应该是模范件。以是,在面对新的缸套和活塞南方双彩网产品的时间重复是不看细致尺寸。多么就会构成很多时间缸套和活塞南方双彩网产品不配套的环境,当大尺寸的气缸配上小尺寸的活塞,就会使二者间隙过大,紧缩有力。
Many repairmen believe that new products should be standardized when repairing. Therefore, in the face of new cylinder liner and piston products, often do not look at the specific size. This will cause many times when the cylinder and piston products are not matched. When the maximum size cylinder is fitted with the smallest size piston, the gap between the two is too large to compress.
五、砂布打磨轴瓦
Five. Abrasive cloth grinding axle bush
刮瓦是挖掘机维修当中技术含量相对较高的一项变乱,很多的缝补工由于自身的技术不过关,就会在举行刮瓦的进程当中直接用砂布举行打磨。但是,在采取砂布举行打磨的进程当中砂布上的沙粒极度容易嵌入到合金当中,加快柴油机轴颈的磨损。
Scraping is a relatively high technical content in the maintenance of the excavator. Many repairmen will wear it directly in the process of scraping because of their own technology. However, when the abrasive cloth is used for grinding, the sand grains on the sand cloth are very easy to be embedded into the alloy so as to accelerate the wear of the diesel engine journal.
六、螺栓冒逝世拧紧
Six. Tighten the bolt
在挖掘机维修的进程当中,着实并不是螺栓拧的越紧越安全的。这紧张是由于很多部位针敷衍螺栓的转矩都是有要求的。但是,很多的缝补工并不这么以为,他们会尽约莫的将其拧到紧,这就容易构成螺栓拧断约莫是螺纹滑扣。
In the process of excavator maintenance, it is not the tighter bolt safety. This is mainly because many parts are required for the torque of bolts. However, many repairmen do not think so. They will tighten them as tightly as possible, which will easily cause bolts to break or thread slips.
七、轮胎气压太高
Seven. The tire pressure is too high
要是是轮式挖掘机,在给轮胎举行充气的进程当中,很多的缝补工并不过细轮胎气压的标题。这就容易构成夏季工程车辆爆胎的外形发生。
If a wheel excavator is used to inflate the tire, many repairmen do not pay much attention to the problem of tire pressure. This will easily lead to the occurrence of tire blowout in summer.
八、采取明火加温活塞
Eight. Heat piston with open fire
在陈设活塞销的进程当中,应该先让活塞受热紧缩。很多的维修职员为了希图方便,直接将其放在明火上举行加热。但是,由于活塞各部位的薄厚是不匀称的,放在明火上加热就会构成其受热不均,后容易引发变形。以是,准确的加热要领,是应该将活塞放入到热油当中举行加热。
In the process of installing piston pin, the piston should be expanded by heat. Many maintenance personnel directly put them on the open flame for heating purposes. However, because the thickness of each part of the piston is uneven, heating on the open flame will cause uneven heat and finally cause deformation. Therefore, the correct way of heating is to put the piston into the hot oil for heating.
九、气缸间丈量不准
Nine. Inaccuracy in cylinder measurement
丈量气缸间隙,应该在活塞裙部垂直于活塞销孔的方向丈量。但是,很多的缝补工在丈量的时间,就会由于暂时不过细在别的方向举行丈量。但是,由于其裙部断面为椭圆形,以是,气缸间隙并不相称。
Measuring cylinder clearance should be measured in the direction of piston skirt perpendicular to piston pin hole. However, many repairmen do not pay attention to other directions when they are measuring. However, because the skirt section is elliptical, the cylinder clearance is not equal.
