【Summary Description】 DTH drill rod/how to use the DTH drill impactor?

潜孔钻杆

The piston, inner cylinder, air seat, check valve and drill bit accessories are installed in the slender outer cylinder. The outer cylinder has an upper joint with a wrench port and a connecting thread, and the lower end is equipped with a threaded connection clamp sleeve.

DTH Drill Pipe/DTH drill impactor Compressed gas through the drill pipe into the impactor, and then discharged from the drill bit, the exhaust gas is used to discharge ballast. The rotary motion of the impactor is provided by the rotary head, and the shaft thrust is provided by the propeller, which is transmitted to the impactor through the drill rod. The clamping sleeve is mainly used to transmit propulsion force and rotary motion to the drill bit. The snap ring controls the axial movement of the drill bit, while the non-return valve is used to prevent debris such as rock ballast from entering the impactor when the supply of compressed air is stopped. During the drilling process, the drill bit is pushed into the impactor and pressed on the clamping sleeve. At this time, the piston directly impacts the drill bit to drill rock. When the drill bit is pulled away from the bottom of the hole, it starts to blow strongly.

DTH Drill Pipe/DTH drill percussion device adopts the latest contemporary rock drilling theory to design the internal structure size of the percussion device, so that the percussion device can obtain the most ideal energy transmission, with large single impact and faster rock drilling speed.ItThe unique taper diameter reduction design, if gravel and soil jam occur during drilling, the taper diameter reduction during lifting of the drilling rig can reduce the lifting resistance and greatly reduce the failure of the impactor. In order to prevent dust pollution in the drilling operation, the main parts of the product also adopt a special computer program-controlled heat treatment process to facilitate the addition of a small amount of high-pressure water in the compressed air for wet rock drilling to protect the health of the operator.DTH Drill Pipe/The design of the down-the-hole drill impactor allows the user to connect directly with the drill pipe without a reducer joint, reducing the user's production costs. Select the best quality raw materials and the most advanced processing technology, more stable performance, longer life. With the most simple and reliable and easy to assemble and disassemble the internal structure, less failure, easy maintenance.
