For domestic and KQ-150, YQ-150, CLQ80A, ZQS100B, KQG150, CM351, CM-220, T10, CBH-10 and other models submersible drilling rig, drill supporting the implementation of the preferred products. Xuanhua name of Zhengyu Drilling Machinery Co., Ltd. - quality, compressed margins, to maximize the profits to our friends, the company timely delivery, perfect after-sale, you are welcome to come to inquiry ..... Impact Model are: low pressure CIR65,70,80,90,110,, 130,150,170, 930, 940 in the pressure, high pressure DHD340,330,345,350,355,115,140,360,380 additional name of Xuanhua New products Zhengyu Drilling Machinery Co., Ltd. - fast impactor 345,355 also listed [350] Features MDZY impactor high pressure DTH hammer has a fast action, the impact energy, less gas consumption, long service life advantages. Widely used in ground project for diving all kinds of hard, high-hardness and resilience of poor drilling rock, which is characterized as follows: This class has a strong impact design hair system, you can have all the high-pressure gas for slagging, keep the hole bottom cleaning purposes; hardened wear can turn around and use the outer sleeve, thereby extending the replacement period. Design transfer airlock, according to rock hardness, wear resistance, drillability different adjustment slagging gas consumption, in order to achieve the best effect of slag, so as to achieve maximum drilling efficiency; simple structure, less components, coupled with wear-resistant parts, the impact of the working longer; front joint with a long screw and the outer cylinder coupled to the disassembly bit easier.
