Drill impactor offerQC70/80/90/100-DTH impactor are offered in the light of  the dead situation at home and abroad the existing product mix and customers in the use, and they are innovation, optimize, design, patent a new generation of products, the product Taper joints, adjustable three-in-one can be used in energy, transportation, metallurgy, building materials industries, such as perforation, rock operations. Drill Impactor advantaes
QC70/80/90/100 DTH-impact, uses a single piston, valves and the board after the central exhaust joints and adjustable combined joint position adjustable from directly before the adjustable variable taper changed.
First, this design can not directly adjustable joints and drill pipe connections, reducing production costs.
Second, the drilling and diameter taper when Card mixed rock and soil had to die, put on the rig when the taper can be adjustable to reduce the resistance has greatly reduced the impact it Explorer does not mention the failure occurred, to reduce the cost of production.
In order to prevent perforation of the rock dust pollution operation of the main components of the product also uses a special computer program of the new heat treatment technology for the benefit of adding a small amount of compressed air in the high-pressure water, wet rock in order to protect the health of the operator.Drill impactor parameters
