Hengwang factory HWZ-120 large hole water well drilling rig
The small track positive circulation drilling rig is mainly used for engineering dewatering wells, agricultural wells, and geothermal drilling. It has the advantages of compact structure, fast footage, flexible and efficient. Lightweight and compact, fast hole forming speed, about 30 meters per hour, low noise, single person can complete the operation, the machine self-unloads the drill rod, the average removal of the 100-meter drill rod takes 10 minutes, easy to move, after completing drilling, start the diesel engine You can complete the shift.

Main Feature:
-Mud circulation is mostly used, the hole wall is stable and is not restricted by the formation.
-Even if there is a small leakage in the circulation system, the circulation will not be interrupted. As long as the flushing fluid can be continuously replenished, drilling can still continue.
-The equipment is small in size and light in weight, and the construction technology is easy to master.
-The backflow velocity of the flushing fluid is low, and large-sized drill cuttings cannot be discharged in time. These drill cuttings are repeatedly broken by the drill bit at the bottom of the hole, which increases the power consumption of the drill bit and accelerates abnormal wear of the drill bit.
