Regularly lubricate all necessary parts. This can not only reduce friction between components, decreasing wear, but also prevent rust, protecting the mechanical parts. Proper lubrication is one of the secrets to keeping the drilling rig running smoothly.
Third, the structure of the drilling rig:
The drill tool is composed of drill pipe, ball tooth drill bit and impactor. When drilling, two drill rods are used to drill. The reverse air supply structure is composed of a reverse motor, a reverse reducer, and a reverse air supply inverter. The reverse reducer is
