Original title: See how Wassara, a mining company, uses metal 3D printing to solve deep drilling problems? The mining industry needs new drilling solutions to cope with increasing cost versus benefit pressures. Compared with the current drilling scheme, the new scheme is not only more environmentallh-pressure water jets and do not use grease for lubrication,Tapered Rock Bit, so they do not pollute the air or groundwater. In addition, high-pressure water is effective in suppressing dust. The incompressibility of water is a key factor in the efficient operation of the Wassara Dth hammer. Wassara's technology results in significant energy cost savings compared to relatively conventional pneumatic Dth hammer technology because less energy is required to drive a hydraulic Dth hammer. High pressure water was selected by Wassara as the transmission medium due to its ability to drive the hammer to produce high frequency, high energy impact motion. In addition,mining dth bit, when the flow leaves the hammer, it is fast enough to bring the drilled core and debris back to the surface and clean the hole. This technologhe-hole hammer is made up of a number of complex components. The core component of the down-the-hole hammer is a sliding shell which provides two-way high-pressure water diversion for the piston assembly, dth drilling hammer ,dhd drill bit, and the inside of the shell requires a plurality of high-pressure water flow holes; due to the complexity n cause of equipment failure). A third drill test was then carried out by Wassara,overburden drilling systems, this time for a duration well beyond the normal Dth hammer cycle, in order to establish as far as possible whether there was any evidence of pitting, but there was still no pitting. This leads to the preliminary conclusion that additive components made of maraging steel have superior potential pitting resistance compared to conventional sliding enclosures made of standard alloy steel.
