A hydraulic drilling rig is a drilling rig that uses oil pressure to drive and control all moving parts. This type of drilling rig uses high-pressure variable oil pump and variable oil motor to realize stepless speed change, which can simplify the transmission mechanism and remove the gear box, which not only reduces the weight of the drilling rig, but also makes full use of the power. At the same time, the drilling rig has high speed, stable work, convenient and safe operation, easy to realize automation and instrumentation, and has good adaptability to high-speed small-diameter drilling (such as diamond drilling) and high-torque and low-speed engineering drilling.

Features of hydraulic drilling rig:

1. The power head hydraulic drilling rig is composed of the following parts: hydraulic pump station, power head, frame, console, column support, etc.

2. It is convenient for underground transportation and installation because of the sub-bulk structure.

3. Unique hydraulic system, full hydraulic transmission, easy operation and labor-saving.

4. Because it is connected by tubing and equipped with blowout prevention drill pipe, the operator can stay away from the wellhead when the drilling rig is working, which is safer.

5. When the drilling rig is working, the support of the power head frame is a frame type support, and several drilling holes can be drilled up, down, left and right in one installation, which saves auxiliary time and has high efficiency.
