Operation and maintenance Of Drilling Hammer: 1、Because the drive chuck and top sub of the Drilling Hammer are all right-handed threads, the Drilling

Series DHD Water Well DTH Hammer are designed as a hammer drill. They differ from other rock drills, however, through continuous operation down agains

Construction Technology of Reverse Circulation Drilling Rig

Typically, there is a 3/4" to 1 12" difference in diameter between the drill bit and drill pipe. It is essential to guarantee that the air compressor

DHD/SD/QL high wind pressure impactors are utilized in combination with Eccentric Casing System drilling equipment.

The major part of the drilling rig, a device that transfers impact energy, directly touches the rock, and bursts is a DTH Rock Bit.

Whether it is in the selection of materials or the production process, we are all to improve the service life of the shank adapter.

In general, drifting, tunneling, and extension applications with strong bending loads are better suited for male shank adapters.

DTH Button bit wear patterns vary depending on the type of ground and the drilling parameters:

The primary goal of the heat treatment of the Shank Adapters is to prevent the shank from piling up and collapsing as a result of the piston's high-fr

Fatigue fracture is the most common kind of failure for Rock Drill Extension Rod, which primarily occur in the threaded part and transition groove reg

The tooth series has a long cycle of passivation, and its non-wear life is about 5-6 times of the grinding life of the same diameter blade head.
