Crawler Mounted Dth Hydraulic Water Well Drilling Rig 200m Diesel Engine Borehole

Crawler Mounted DTH Drilling Rig 200m Diesel Engine Water Well Drilling Rig Borehole Machinery Drilling Welling Rig

ST 350  Pneumatic Borewell Machine Breif Introduction:

ST350 series water well drilling rig is a light, efficient and multi-functional drilling and drilling equipment. It is mainly suitable for industrial and civil drilling and geothermal drilling. It has the advantages of compact structure, fast footage, flexible movement and wide application area. It is especially suitable for taking water from mountainous and rocky strata.

This machine can be applied to various formations, such as water well engineering, geothermal wells, anchor pile holes, etc., and can use heel drills. It has the advantages of hydraulic control of the whole machine, automatic loading and unloading of drill pipe, crawler type chassis, high horsepower diesel engine, four-corner hydraulic balance and stronger terrain application ability.

ST 350 Pneumatic Borewell Machine Parameter:

The use of pneumatic water well drilling rig in rock and complex layers has the following advantages:

(1) High slag discharge wind speed, clean hole bottom and no secondary crushing; Because there is no liquid column pressure, the hole bottom crushing condition is improved without groundwater;
(2) The drilling method of pneumatic water well drilling rig is to impact the hole bottom with high frequency, which reduces the influence of hole inclination on rock or inclined stratum, so as to improve the verticality of drilling hole and reduce the rock collapse of hole wall;
(3) Compared with rotary well drilling rig, pneumatic well drilling rig requires much less WOB and torque. This can reduce the quality and capacity of drilling equipment and create favorable conditions for large-diameter hard rock drilling;
(4) Pneumatic water well drilling rig has good adaptability and can work under various complex rock strata (including aquifer);
(5) The utility model has the advantages of simple structure and convenient use and maintenance.

This series of rigs use excavator crawler chassis for off-road performance. The independent module design allows the rig to be mounted on the truck for increased maneuverability. The two-speed swing and propulsion speed can meet the different piercing needs of the stratum and rock formation. The combined positioner can adjust and replace the positioning plate according to different types of drill pipe and impactor to ensure accurate and reliable positioning and centering. The hoisting mechanism facilitates the lifting of the drill pipe and the impactor to reduce labor intensity.
