Mobile ST 300 Meters Large TUV Rotary Head Drilling Rig Equipment

Product Specification

Mobile Rotary Drilling Rig ST 300 Meters Large Pneumatic Borewell Machine

ST 300 Meters Large Pneumatic Borewell Machine Product Descrption:

Drilling rig, hydraulic torque converter, automatic transmission, lever shift, forward and reverse switching is sensitive and convenient, transmission efficiency is twice as high as hydraulic transmission, power consumption is reduced by 35%, more efficient and energy-saving. The difficulties of air DTH hammer drilling in soil layer and low construction efficiency of rotary drilling machine in hard rock, gravel and cobble layer are solved.top hammer drill rigs are equipped with powerful hydraulic rock drills that offer high penetration rates, reliability, and excellent fuel economy.

ST 300 Meters Large Pneumatic Borewell Machine Main Parameter:

ST 300 Meters Large Pneumatic Borewell Machine Main Advantages:

1. The speed range of the drilling rig is 14-1030r / min, and the maximum output torque is 9500n. M.

2. The drilling rig adopts long travel speed doubling mechanism and mechanical power head with a stroke of 3500mm, which is used to improve drilling efficiency and reduce drilling plugging and burning accidents.

3. The drilling rig adopts double oil pumps for oil supply, single pump for drilling and two pumps for combined flow for lifting and tripping; Less power loss and short auxiliary time.

4. Crawler chassis is adopted, the stroke of outrigger cylinder is 1.5m, it can be loaded automatically, and it is convenient to move and transport.

5. The drilling machine is in mechanical operation. Some functional interfaces are reserved in the hydraulic system, which can be expanded according to the process requirements of different users.

ST 300 Meters Large Pneumatic Borewell Machine Operating Instructions:

During the working process of water well drilling rig, the pump is used for reverse circulation operation. Under the action of atmospheric pressure, the circulating fluid flows from the sedimentation tank to the bottom of the well through the return ditch along the annular gap of the well. At this time, the rotary table drives the drill pipe to drive the drill bit to rotate for drilling. The negative pressure established by the suction of the mud pump sucks the debris mud into the inner cavity of the drill pipe and discharges it into the sedimentation tank through the mud pump. The circulating fluid after sedimentation continues to flow into the well, The reverse circulation drilling work is formed.
