Release time:
Jan 02,2024
Holes are created by breaking up rock layers using the rotary motion of drilling tools. Major types include large and small churn drills, positive and reverse circulation rotary drills, hydraulic power head drills, and down-the-hole vibrating rotary drills.
A pressure drill rig, also known as a hydraulic drill rig, can perform coring drilling and full-hole drilling without coring, and can also be used with a winch for impact drilling.
Hydraulic drill rigs have the following advantages over manual drill rigs:
① Accurately maintain bottom-hole pressure according to the pressure gauge reading;
② Significantly reduce the labor intensity of workers during operation;
③ Prevent injuries caused by the sudden drop of drill string and the flipping of the feed handle;
④ Can be used as a hydraulic jack when a drill is stuck or when handling malfunctions;
⑤ Some rigs are equipped with a moving oil cylinder that can automatically move the rotary head away from the open hole;
⑥ Some are equipped with a pipe wrench that can automatically tighten and loosen drill pipes.
