Description:
The down-the-hole impactor is an integral part of the down-the-hole drilling rig and belongs to the working device of the down-the-hole drilling rig. DTH impactors are divided into low wind pressure DTH impactors, medium wind pressure DTH impactors, and high wind pressure DTH impactors.
Technical parameter:
Features:
High-pressure DTH hammer has the advantages of fast action, large impact power, less gas consumption, long life, and so on. Widely used in geotechnical engineering to create all kinds of hard, hard, poor drillability of rock tenacity, its features are as follows:
1 The impactor design has a strong blower system, and high-pressure gas can be used for slag discharge, making Kong Di cleaning; the wear jackets hardening tube can be a U-turn, so you can extend the period of replacement;
2 Design of the adjustable gas plug, according to rock hardness and abrasion resistance, can discharge gas drilling different adjustments, in order to achieve the best effect of slag, so as to achieve the highest efficiency;
3 Simple structures, few parts, plus the use of wear-resistant parts, the impact of the working time longer;
4 Before the joint using a multi-thread and the outer cylinder connection, the impact of the removal of the drill bit is easier.
Application:
DTH drill hammer is mainly used in hydrology and water well drilling, geological drilling without core, geological disaster prevention engineering, and mine drilling and other fields. Suitable for gravel and hard rock applications configure the special structure of the drill can also be used in soft soil. ROP is generally much higher than hydraulic impactor drilling but requires a larger air compressor with capacity, greater fuel consumption, noise, and dust pollution. Drilling depth by the groundwater level, and water influence.
