Characteristics of drilling rig: (1) with oil pressure automatic feeding mechanism, improve drilling efficiency, reduce the manual labor intensity of workers. (2) The ball clamping mechanism is used instead of the chuck, and equipped with a clamping and positioning mechanism. (3) It is equipped with a pressure gauge at the bottom of the hole to indicate the pressure, which is convenient for mastering the situation in the hole. (4) Centralized handles and convenient operation. (5) The structure is compact, the drilling rig and the power machine are both installed on the same base, and the occupied area is small. (6) Light weight, strong decomposability, convenient relocation, and suitable for work in plain or mountainous areas. (7) Equipped with safety shield, highlighting the humanized design features of equipment. (8) A fixed nut is installed at the joint between the lower end of the feed cylinder and the vertical shaft box, which improves the reliability of the drilling rig.Gk

How to deal with sticking of water well drilling rig
During the drilling operation of water well drilling rig, the common problem is sticking. The phenomenon that the pipe string and tools can not be lifted, lowered or rotated in the well is called sticking. In case of this phenomenon, the drilling rig can no longer work normally.
According to the current strength of the drill bit, the broken wing has been basically eliminated. In case of special circumstances, a section of seamless pipe with a diameter almost the same as the hole diameter can be used. The pipe is filled with butter, asphalt and other materials, which are connected with the drill pipe into the hole bottom. The broken wing at the hole bottom is taken out. The rock powder at the hole bottom is blown out before fishing.
In severe cases, the drilling tool can not be lifted or put down, and the impactor does not sound. At this time, only external torque or auxiliary tools can be used to help promote the drilling tool, so as to make the drilling tool rotate. Then, the drilling tool should be promoted while supplying gas until the fault is removed. When re drilling, pressure shall be applied first, and then the propulsive force shall be gradually increased until the normal working pressure.
