Engineering drill include: impact drilling rig, engineering composite drill, rotary well drilling rig. Below we Depending on the application range and characteristics of different projects rig, to provide the basis for the selection of drilling rig. Impact drilling rig by drilling vertical reciprocating motion of a large drilling rig manufacturers, the impact of drilling meat situation, broken rock, simple structure, no circulatory system, debris removal can not be large-scale projects engineering drill rig and colleagues compared the efficacy and therefore low drilling depth is generally less than 250 meters, sometimes up to 500 to 600 meters. Composite Rig additional impact mechanism on the basis of the turntable on the rotary drilling rig to the main rotary drilling, when faced with gravel layer is the impact of dual-well drilling rig drilling large engineering drilling rig equipment, adapt to a variety of formations strong. Another is to combine the role of impact with the rotary drilling well drilling rig. Rotary well drilling rigs, rotary motion of the drill rely broken rock drilling holes. When the job force by the actuator driving wheel, driven by the initiative of rock broken drill bit rotation. Rig Hydraulic rotator principle structure its upper cylindrical form the inlet chamber, the side has all the inlet tube, the sand pump drilling fluid delivery over tangentially into the cavity. At the top center of the vortex tube, whereby the drilling fluid after treatment overflows. Lower housing is conical. Usually at the bottom of the cone angle of 15 degrees to 20 degrees to discharge solid sand discharge port. Quality large solid particles subject to greater centrifugal force sufficient to overcome the friction of the drilling fluid, thrown to the inner wall of the cyclone and the cyclone downward by gravity, sand discharged from the discharge port; and small mass solid particles and light drilling the spiral, through the overflow tube output. CONSERVANCY cyclone separating solid particles of smaller diameter large drilling rig where to sell, the greater separation capacity, it is the size of the cyclone, into the pump pressure, drilling fluid viscosity and solid particle distribution and so on. Since the drilling fluid solid phase particles at high speed hit the inner wall of the cyclone and fall rapidly rotating along the inner wall, the inner wall of the cyclone quickly often leads to wear, damage.
