ST 350 Crawler Mounted Drilling Rig 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.
Configure appropriate water pump
After the well is completed, measure the water level of the water outlet well and the corresponding water output according to the drainage condition of the drilling machine, and then determine the total head of the water pump according to the height difference from the ground to the dynamic water level and the irrigation method you adopt, and the required working head of the water pump. The flow of the water pump shall not exceed the water flow through the well. The corresponding water pump shall be purchased on the premise of the above two items.
