Product Application Scope
How to solve the well bit slips?
After two times of tripping in, the thickness of the muck is determined through the number on the display. After looking at the soft and hardness of the dropped address, if there is a lot of soil and it is hard clay, a drill bucket smaller than the pile diameter is used to solve the problem of slipping. Because there is a large gap between the diameter drill bucket and the hole wall, the dropped soil is under the action of the total amount of drill pipe bucket and pressure, Through the gap between the drill bucket and the hole wall, the small-diameter drill bucket can normally drill when it contacts the solid soil. The large-diameter drill bucket is squeezed into the small hole after two times of running in, so that the large-diameter drill bucket can normally enter the small hole
