ST 300 Pneumatic Borewell Machine Features:
1. Hydraulic automatic feeding mechanism is adopted to improve drilling efficiency and reduce labor intensity.
2. The ball clamping mechanism or hydraulic chuck is adopted, and there is no need to stop to change the rod. The operation is convenient, safe and reliable.
3. Hashole bottom hole pressure gauge is convenient to master the situation in the hole.
4. Compact structure, centralized handle, small floor area, light weight, strong decomposition force and convenient movement. It can be operated in plains and mountains.
The main causes of drill pipe fracture are:
1, The bending moment of drill pipe is too large in the process of reaming and pipe pulling back;
2, The reasons for the excessive bending moment are as follows: first, the actual curve of the guide hole deviates greatly from the theoretical curve; Second, the hole after reaming is irregular, which makes the pipe form an included angle with the reamer and the drill pipe axis.
Operating Instructions:
During the working process of water well drilling rig, the pump is used for reverse circulation operation. Under the action of atmospheric pressure, the circulating fluid flows from the sedimentation tank to the bottom of the well through the return ditch along the annular gap of the well. At this time, the rotary table drives the drill pipe to drive the drill bit to rotate for drilling.
