It can be said that every excavator apprenticeship begins with butter, which sounds like a "light" behavior that makes the excavator work better every day. Why is it seeming to be light, because the butter is a real individual, and some of the apprentice is exhausted by the halves, and finally the master is coming through the butter.
So why do the excavators need butter? How often do you play? Is it possible to use gear oil instead? Today, Xiang is coming to reveal the secret to everyone!
Why do you need butter?
When the excavator is working, there are ten positions on the arm and the bucket of the excavator, which will have relative motion. The pin and sleeve of these parts have been rubbed at work, and the force of these parts is very large because of the large working load of the excavator.
4 pin shafts on the excavator bucket need to be lubricated
This can be true steel real iron, such a big work strength under the appointment of its "dry grinding", shaft pin and axle sleeve will have serious wear and tear, can not be used a few days gap is very large, the work of the excavator and maintenance and replacement cost. In order to reduce this part of the friction, the excavator has designed a lubricant injection and retained channel at these moving parts, allowing every two moving parts to form an oil film in the middle of the work, reducing wear. And this lubricant is butter, scientific name grease.
How often do you need to make a butter?
In order to make the excavator work better, each excavator is marked with each part of the maintenance time in the instructions, and the butter is usually 5-8 hours a time added to the working time, that is to say, at least one time of butter is needed at work every day.
Concentrated lubrication points on the Liugong 936E excavator
When the excavator is apprenticed to the apprentice, this work is usually completed by the apprentice. There are ten different positions of lubricating points on the excavator's arm and the bucket. Each lubricating point needs to use the butter gun to "press" eight or nine times during the lubrication.
Can you use gear oil or oil instead?
Some people may ask, why not use gear oil? How good it is to pour directly into it, so tired without butter.
The butter filler from the bucket shaft of the excavator
In fact, this is due to the characteristics of the work of the excavator. The working parts of the excavator are all "low speed heavy load", and the sealing is not good. If liquid lubricating oil is used in the work, it is easy to leak out and can not form a good oil film. Therefore, the shaft pin of the front end of the excavator needs to be filled with grease, the retention time is long, and the oil film can be formed in each lubricating part to keep good lubrication.
In the end, he would like to say that butter is very good for the excavators, and the speed of the pin and shaft wear will be much slower, and the gap between these parts is small. The noise and precision of the excavator will be much better, so Xiang wants to say to the apprentices who are digging the excavators. It's not hard for you to make butter every day. This is the basic skill to learn the excavators. Even if the excavators don't understand how to love them, how can you learn to control this big guy, right!
