Dayu Drill Rig Machinery Co. Ltd.

Zhengzhou, Henan, China

Submersible drilling rig, including open dth xuanhua manufacturing pneumatic tools truck mounted water well drilling rig plant in cooperation with the united states ingersoll-land in the cm-351 split pressure submersible drilling rig, as well as co-production with sweden atlas-copco cbh-10 pressure integration the rig, working pressure up to 1.6 mpa. Cs-165e open hole drill independently developed by the changsha institute of mining research, not only to improve the working gas pressure 1.6-1.8 mpa, and through the use of dual power drive, to achieve long-distance walking; drill arm structure with multiple degrees of freedom, improved rig ability to adapt to the venue, no appointment screw air compressor of auxiliary rig; hydraulic technology, highly integrated system is simple, functional and reliable; plc control, and canbus bus technology, fully automatic operation, fault diagnosis, malfunction protection and public data mobile communications network equipment such as remote monitoring and management functions; using a new type of disc drill pipe library, ensure the rig drilling depth. Large high pressure submersible drilling rig, and greatly improve the technical level of china's open pit mine drilling equipment, promote technological progress of china's mining industry, hydraulic drill rig china's mining industry equipment and technical levels among the international advanced level, a strong impetus to our mining the development of the industry. On the overall level of china's open pit mine drilling equipment compared with foreign countries is relatively backward, the majority of mine also use domestic seventies developed mechanical conventional pneumatic submersible drilling rig or rotary drill, only a few countries focus on large-scale mining use imported high pressure submersible drilling rig.

We are offering domestic metal mine open pit mining the integrated drilling rig for sale perforation equipment including cone drill, dth drill and kowtow drill the kowtow drilling have been phased out. The rapid popularization and application of the rotary drill, changing the backwardness of the open pit perforation equipment. Some open metal mines the united states be has introduced, gd the company's rotary drill. Mainly be produced coins 250 mm 45r, 47r rotary drill dollar 310 mm 60r hydraulic drilling rigsas well as state-of-the-art 310 mm mine perforation drilling speed is greatly increased efficiency in the hard rock station 9-15m reach 1525 m, in hard rock and water well drilling equipment for sale soft rock up to 30m. Sets annual efficiency of about 5} 60, 000 m of up to 8-10 meters high. Open pit metal mines made rotary drill changsha institute of mining research hengyang nonferrous metallurgical machinery plant development and production of type yz-55 of type yz-35 and yz-12 type rotary drill, were used in the drill rig for sale small open pit drilling operations. Yz-55-type rig pore size of 280-380 mm, the time drilling depth 16.518.5 mo yz-35 rig aperture for 170 270 mm the drilling depth 17-18.5 ma yz-12 rig pore size of 70 to 95 mm, drilling depth of 7.5-12.5 m. -yz-35 and yz-55 type rotary drill the drill rigs structure and parameters is roughly equivalent to the the be company 45r and 60r class type rotary drill level, is the most successful domestic development of two rotary drill. Domestic rotary drill luoyang mining machinery plant, jilin heavy machinery plant, jiangxi mining machinery plant ky series, its specifications ky-150, ky-200, ky-250, ky-250a, ky-310 drilling diameter from 150 - 310 mm, perforation depth range of 1520 m.
