Deep Water Drilling Machine Pneumatic Drilling 350m Crawler Well Drilling Rig Drilling Equipment
ST 350 Pneumatic Borewell Machine Breif Introduction:
The birth and development of pneumatic water well drilling rig is a major revolution in drilling technology. It has changed the traditional way of cutting and grinding broken rock, broken the rock into volume, and greatly improved the drilling efficiency and adaptability to hard and complex strata. Its remarkable technical and economic benefits are regarded as one of the symbols of modern drilling technology and measuring drilling technology, It is valued by the drilling industry at home and abroad. Pneumatic DTH hammer drilling mainly starts from drilling blasting holes, water well foundation rock holes and geological exploration holes. In order to expand its application scope, such as hook form and working performance of DTH hammer, researchers at home and abroad make it meet the requirements of various engineering applications.

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.
