小型两头忙搅拌车维修应该注意什么?

作者:http://www.zkzsljbc.com 时间:2021-06-18

1.随机黄油
1. Random butter
黄油的主要功能是润滑和密封。因此,维护人员有时会在维护工作期间填充小型两头忙的气缸盖垫圈,以提高机器柴油发动机的密封性能。但是这种方法确实是错误的。这是因为在气缸盖垫圈上涂油脂时,拧紧气缸螺栓后,一部分油脂会流入气缸中。高温影响后,残留在外部的润滑脂在汽缸盖垫圈,汽缸盖和车身表面之间形成一定的间隙,从而降低了汽缸垫圈的原始密封性能。
The main function of butter is to lubricate and seal. Therefore, the maintenance personnel sometimes fill the small cylinder head gasket busy at both ends during the maintenance work to improve the sealing performance of the diesel engine. But this method is really wrong. This is because when grease is applied to the cylinder head gasket, part of the grease will flow into the cylinder after tightening the cylinder bolts. Under the influence of high temperature, the residual grease forms a certain gap between the cylinder head gasket, the cylinder head and the body surface, thus reducing the original sealing performance of the cylinder head gasket.
2.不要换油
Don't change the oil
小型两头忙在工程机械中起着特别重要的作用,许多修理工对此都非常重视。完全按照标准要求添加。但是,许多维修人员忘记检查两头忙的油质并更换变质的油。简单地添加发动机机油并长时间更换,将导致发动机的许多零件在润滑不足的环境中运行,从而导致比平时更大的磨损。另外,在操作柴油发动机时,机油中还含有很多污垢,因此,如果不定期更换机油,极有可能发生
Small two busy in construction machinery plays a particularly important role, many repairmen attach great importance to this. It is added completely according to the standard requirements. However, many maintenance personnel forget to check the busy oil quality at both ends and replace the deteriorated oil. Simply adding engine oil and changing it for a long time will cause many parts of the engine to run in the environment of insufficient lubrication, resulting in greater wear than usual. In addition, in the operation of diesel engine, the oil also contains a lot of dirt, therefore, if the oil is not changed regularly, it is very likely to happen

3.无需将小型两头忙的缸套和活塞产品安装结合在一起
3. There is no need to combine the small cylinder liner and piston products
许多维护人员认为,新产品需要作为维护的标准零件。因此,面对新的缸套或活塞产品时,通常会忽略某些尺寸。这通常会导致两头忙的缸套和活塞产品之间出现差异。如果较大的气缸配备了最小的活塞,则两者之间的间隙将变大,而压缩力将变弱。
Many maintenance personnel believe that new products need to be used as standard parts for maintenance. Therefore, when facing new cylinder liner or piston products, some dimensions are usually ignored. This usually leads to a difference between the busy cylinder liner and piston products. If the larger cylinder is equipped with the smallest piston, the gap between the two will be larger and the compression force will be weaker.
4.小型两头忙使用明火加热活塞
4. The small two ends are busy using open fire to heat the piston
小型两头忙的活塞销的安装过程必须首先加热液压小型两头忙的活塞并为其充电。为了方便起见,许多维护人员会在直射的阳光下对其进行加热。但是,由于活塞各部分的壁厚不均匀,直接火焰加热会引起不均匀加热并最终变形。因此,正确的加热方法是用热油加热活塞。
During the installation process of the small piston pin with two busy ends, the hydraulic small piston with two busy ends must be heated and charged first. For convenience, many maintenance personnel will heat it in direct sunlight. However, due to the uneven wall thickness of each part of the piston, direct flame heating will cause uneven heating and eventually deformation. Therefore, the correct heating method is to heat the piston with hot oil.
