高赔率网投平台租赁为什么要打黄油?

日期:2020-05-27   来源:
挖掘机在工作时大小臂和铲斗上有数十个位置会发生相对运动,这些部位的销轴和轴套工作时一直发生着摩擦,并且由于挖掘机工作负载大,这些部位的受力也是非常大。
When the excavator is working, there are tens of positions on the big and small arms and the bucket that will move relative to each other. The pin shaft and the shaft sleeve of these positions have friction all the time when they are working, and because of the large working load of the excavator, the forces on these parts are also very large.

这可都是真钢实铁,这么大的工作强度下如果任由其“干磨”,轴销和轴套都会发生严重的磨损,用不了几天间隙就非常大,影响挖掘机的工作并且维修更换成本高。为了减少这部分摩擦,挖掘机在这些运动部位都设计了润滑剂注入和留存通道,让每两个运动部件在工作时中间都能形成油膜,减少磨损。而这个润滑剂就是黄油,学名润滑脂。
This can be real steel and solid iron. If it is allowed to "dry grind" under such a large working intensity, the shaft pin and shaft sleeve will be severely worn. In a few days, the clearance will be very large, affecting the work of the excavator and the maintenance and replacement cost is high. In order to reduce this part of friction, the excavator has designed lubricant injection and retention channels in these moving parts, so that every two moving parts can form an oil film in the middle of work, reducing wear. And this lubricant is butter, a scientific name for grease.
多久需要打一次黄油?
How often do I need to beat butter?
为了让挖掘机更好工作,每台挖掘机在使用说明书上都标注了每个部位的保养时间,而黄油一般是工作时间隔5-8小时加注一次,也就是说每天工作时都至少需要加注一次黄油。
In order to make the excavator work better, the operation manual of each excavator has marked the maintenance time of each part, and the butter is generally filled every 5-8 hours during the working time, that is to say, the butter needs to be filled at least once every day.

而当挖掘机上带了学徒时,这项工作一般就交由学徒来完成了,挖掘机的大小臂和铲斗上有数十个不同位置的润滑点,每个润滑点在润滑时都需要使用黄油枪“压”八九次,这么多个位置每天打一遍还真是个体力活。
When the excavator is equipped with an apprentice, the work is usually done by the apprentice. There are dozens of lubrication points on the large and small arms of the excavator and the bucket. Each lubrication point needs to be "pressed" by the grease gun eight or nine times during lubrication. It's really an individual activity to play so many positions once a day.
能不能使用齿轮油或机油替代?
Can gear oil or oil be used instead?
也许有人会问,为什么不能使用齿轮油呢?那直接倒进去多好,不用打黄油那么累。
One might ask, why not use gear oil? It's better to pour it directly. It's not as tired as butter.

其实这是由于挖掘机工作时的特性导致的,挖掘机的这些工作部位都属于是“低速重载”,并且密封性不好,如果使用液态润滑油在工作时很容易漏掉并且无法形成良好的油膜。所以在挖掘机前端工作装置轴销处需要加注润滑脂,留存时间长,并且可以粘在每个润滑部位形成油膜,保持良好润滑。
In fact, this is due to the characteristics of the excavator when it works. These working parts of the excavator are all "low speed and heavy load", and the sealing is not good. If liquid lubricating oil is used, it is easy to leak out and can not form a good oil film. Therefore, the front end working device of the excavator needs to be filled with lubricating grease, which has a long retention time and can form an oil film on each lubricating part to maintain good lubrication.
