小型搅拌车在某些行业的运输方面可谓是不可或缺的,不过近期很多用户向我们咨询为什么它的工作效率越来越低,那么出现这一状况的原因可能是因为没有及时保养维修,再者或许是因为没有正确的保养,相信后者所占的比例应该是很大的,那么具体它有哪些保养禁忌呢?一起来看我们龙装工贸的详细介绍。
Small mixers are indispensable for transportation in some industries, but recently many users have asked us why their work efficiency is getting lower and lower. The reason for this may be that they are not maintained in time, or that they are not maintained correctly. I believe the latter should account for a large proportion, So what are the specific maintenance taboos? Let's take a look at our detailed introduction to Longzhuang industry and trade.
1、忌机油只加不换
1. Avoid only adding oil without changing it
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,很多小型混凝土搅拌车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。一般在正常情况下机油的损耗并不是很大,但是却极容易产生污染,而失去保护柴油机的作用。
Engine oil is essential in the use of diesel engine. Its main functions are lubrication, cooling, cleaning and so on. Therefore, many small concrete mixer drivers pay attention to check the oil quantity of lubricating oil and add it according to the standard, but ignore the inspection of lubricating oil quality and the timely replacement of deteriorated oil, resulting in some moving parts of the engine always operate in a poor lubrication environment, accelerating the wear of various parts. Generally, under normal circumstances, the loss of engine oil is not very large, but it is very easy to produce pollution and lose the role of protecting diesel engine.
在柴油机运转的过程中,许多污物(燃油不完全燃烧而生成的碳烟、积炭和积垢等)都会进入到机油中。对于新的或大修后的机械,试运转后杂质就会更多,如果只加不换就投入使用,容易引起烧瓦、抱轴等意外事故。
During the operation of the diesel engine, a lot of dirt (soot, carbon and dirt generated by incomplete combustion of fuel) will enter the engine oil. For new or overhauled machinery, there will be more impurities after commissioning. If it is put into use without replacement, it is easy to cause accidents such as tile burning and shaft holding.
2、混凝土商砼车忌缸套和活塞新品不经选配即安装
2. It is forbidden to 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一定的公差范围。如把大尺寸的汽缸套配上小尺寸的活塞,会使配合间隙太大,造成压缩无力,而启动困难。
When replacing the cylinder liner and piston, it is considered that the new cylinder liner and piston are standard parts with interchangeability, which can be used after installation. In fact, the dimensions of cylinder liner and piston have a certain tolerance range. If the large cylinder liner is matched with the small piston, the matching clearance will be too large, resulting in weak compression and difficult start.
因此,小型混凝土搅拌车在换装前一定要检查标准缸套与活塞的尺寸分组代号,装用的缸套与活塞必 须使标准活塞的尺寸分组代号与标准缸套的尺寸分组代号一样,这样才能保证两者之间具有标准的配合间隙。
Therefore, before the replacement of small concrete mixer truck, the size grouping code of standard cylinder liner and piston must be checked. The installed cylinder liner and piston must make the size grouping code of standard piston the same as that of standard cylinder liner, so as to ensure that there is a standard fit gap between them.
3、水泥运输车忌不检查柱塞行程余量
3. Do not check the plunger stroke allowance of cement truck
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。调好小型混凝土搅拌车的供油开始时间后,之所以要检查行程余量,是因为柱塞的行程余量与柱塞和套筒的磨损有关。
During the commissioning of plunger fuel injection pump, many maintenance personnel do not pay attention to checking the stroke allowance of plunger. The so-called stroke margin of the plunger refers to the amount of upward movement of the plunger after it is pushed to the top dead center by the cam on the camshaft. After adjusting the oil supply start time of the small concrete mixer, the reason to check the travel allowance is that the travel allowance of the plunger is related to the wear of the plunger and sleeve.
