600 air compressor water well drilling rig

The high-speed rotation of the impactor inside the hole is achieved by a separate rotating mechanism, namely an electric motor or pneumatic rotating device outside the hole, through a drill rod connected to the rear end of the impactor. The rock powder generated during rock drilling is flushed out of the hole by a mixture of wind and water gas. The mixed gas is injected into the impactor through the center of the drill rod by the powder discharge mechanism, and then enters the bottom of the hole through the gas groove on the impactor cylinder body.
