ST350 series deep(water) well-drilling rig uses full hydraulic control, and the Top drive to drive the rotation of drilling tools with very high drilling efficiency.
Reasonable overall layout uses the tractor-mounted or full ground chassis for transportation with good maneuverability.Very flexible in difficult roads and can be widely used in many fields such as resource exploration of hydrology wells, coalbed methane, the shallow layer of shale gas, terrestrial heat, etc, and can also be used for coal-mine gas exploitation salvage work.
The top-mounted driving head principal shaft has a great drift diameter, suitable for many kinds of construction work such as slurry drilling, air drilling, and air foam drilling, meeting the demands for well-drilling at different terrain strata.

Structure composition and configuration of small water well drilling rig?
1. Hydraulic oil pump: it is double connected type. The large displacement pump provides power for the power head, and the small displacement pump provides power for four outrigger cylinders, landing mast oil cylinders and afterburner / lifting pulley oil cylinders.
2. Four legs: small drilling equipment is composed of hydraulic cylinder and fixed frame. It can adjust the levelness of the machine body at the work site to support and stabilize the body.
3. Mast: it is a frame structure composed of giant steel pipe, channel steel and angle steel, with the inner groove of channel steel on both sides as the power head running up and down to ensure the perpendicularity of drilling. The lifting and landing of drilling mast is completed by hydraulic cylinder.
4. Power head: the mechanism of gear reducer is adopted. There is a mandrel with a large hole in the middle of its low-speed shaft. The upper port of the mandrel can be connected with the rubber hose interface of the concrete pouring equipment to pour concrete; the lower port of the mandrel is connected with drill pipe and drill bit through flange. The high speed shaft is driven by a high torque hydraulic motor
