DRC300 crawler pneumatic top hammer drilling rig powered by air compressor, the Top hammer drilling rig is equipped with a high power pneumatic rock drifter, the heavy-duty drill arm and the main parts of this rotary drill rig are all imported from famous international brands, which guarantee the reliable quality of the drifter rock drilling rig, especially realize much less energy consumption of rolling fraction than that of sliding fraction and make the wear of sliding framework be lower.
JK Drilling are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.
Characteristics1. The chassis is driven by highly-efficient pneumatic motor with powerful traction. Each track is drivenindependently by air motor with enclosed gear drive, the gradeability arrives 35° with a compressor, or 50°alone.2. Hydraulic track oscillation is more suitable for positioning drilling machine during drilling..3.The carriage with rollers provides for minimal wear to the drill guide.4.The special compensation device makes a full production of drill rod threads.5.The Hydraulic auxiliary functions are easy and efficient for guide extension, boom swing, boom lift, guidetilt and guide dump.6. competitive in price,low cost of maintain.7.Optional dust in wet and dry.

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.
