自上料搅拌车保养有哪些地方需要注意?

自上料搅拌车的保养是非常重要的,保养做得好不仅能增加工作效率还能一定程度上延长中科自上料搅拌车的使用寿命,下面小编就为大家介绍在保养过程中禁忌有哪些?
The maintenance of self loading mixer is very important. Good maintenance can not only increase the working efficiency, but also extend the service life of self loading mixer to a certain extent. What are the taboos in the maintenance process?
1、忌缸套和活塞新品不经选配即安装
1. Do not install new cylinder liners and pistons without selection
在换装汽缸套和活塞时,认为新的汽缸套和活塞都是标准件,具有互换性,装上去就能使用了。而实际上,汽缸套与活塞的尺寸都是有公差范围,如把较大尺寸的汽缸套配上较小尺寸的活塞,会使配合间隙太大,造成压缩无力,而启动困难。
When replacing the cylinder sleeve and piston, it is considered that the new cylinder sleeve and piston are both standard parts and have interchangeability, so they can be used after being installed. In fact, the size of cylinder sleeve and piston has tolerance range. For example, if the larger cylinder sleeve is equipped with the smaller piston, the fit clearance will be too large, resulting in the weak compression, and it is difficult to start.
2、忌机油只加不换
2. Do not replace the engine oil
机油在柴油机的使用中是必不可少的,主要作用是润滑、冷却、清洁等。因此,很多驾驶员都会注意检查润滑油的油量,且按标准添加,但是却忽略了润滑油质量的检查和对已经变质机油的及时更换,而导致一些发动机的运动机件总是在较差的润滑环境中运转,加速了各机件的磨损。
Engine oil is essential in the use of diesel engine. Its main function is lubrication, cooling, cleaning, etc. Therefore, many drivers will pay attention to check the oil quantity of the lubricating oil and add it according to the standard, but they ignore the inspection of the quality of the lubricating oil and the timely replacement of the deteriorated oil, which leads to the moving parts of some engines always running in the poor lubrication
environment and accelerates the wear of the parts.
3、忌不检查柱塞行程余量
3. Avoid not checking the plunger stroke allowance
在柱塞式喷油泵的调试过程中,有很多维修人员不注意检查柱塞的行程余量。所谓柱塞的行程余量,就是指柱塞被凸轮轴上的凸轮顶至上止点后,能继续上行的移动量。调好自上料搅拌设备车的供油开始时间后,之所以要检查行程余量,是因为浙江自上料搅拌设备车柱塞的行程余量与柱塞和套筒的磨损有关。柱塞与套简磨损之后,柱塞要往上多运动一段后才能开始供油,使供油开始时间推迟。当拧出调整螺栓或换用较厚的调整垫块、垫片之后,柱塞低位置就会上移,使柱塞的行程余量减小。因此,在维修调试喷油泵时,首先就应当检查此行程余量,用以判定喷油泵是否还允许调整。
In the debugging process of plunger fuel injection pump, many maintenance personnel do not pay attention to check the stroke margin of plunger. The so-called plunger stroke margin refers to the amount of movement that the plunger can continue to move upward after it is pushed to the TDC by the cam on the camshaft. After adjusting the start time of oil supply for the loading mixer, the reason for checking the travel allowance is that the travel allowance of the plunger of the loading mixer in Zhejiang is related to the wear of the plunger and sleeve. After the wear of the plunger and the sleeve, the plunger must move upward for a period of time before oil supply can be started, so that the start time of oil supply is delayed. When the adjusting bolt is screwed out or the thicker adjusting block and gasket are replaced, the low position of the plunger will move up, reducing the stroke margin of the plunger. Therefore, when repairing and debugging the fuel injection pump, we should first check the stroke margin to determine whether the fuel injection pump is still allowed to be adjusted.
