Unique taper diameter reduction design. If gravel and soil are stuck during drilling, the taper diameter reduction can reduce the lifting resistance when the drill rig is lifted up, greatly reducing the failure of the impactor to be lifted out.
With this design, users can directly connect to the drill pipe without reducing the diameter joint,reducing user production costs.
The selected raw materials and advanced processing technology ensure stable performance and long service life.
Description:
The impactor of a down-the-hole drilling rig is a key component of down-the-hole drilling rig drilling.
It is used to provide axial reciprocating rock-breaking impact force to the drill bit in order to cool the drill bit and entrain cuttings. It is also the power fluid for downhole power drilling tools. , the structure is shown in the figure below, which mainly consists of rear joint, outer sleeve, check valve, air regulating plug, cylinder, valve seat, piston, guide sleeve, disc spring, snap ring, spring, retaining ring, rubber ring, front Connectors, etc.
