Well drilling rigs drilling in order to meet the needs of different strata, increase drilling efficiency, multi-well drilling rig forward and fully hydraulic steering gear and direction of development: that a wide range of drilling rig equipment and accessories, can impact more drilling mode type, rotary and DTH, etc; also use mud wash well, wash well and compressed air positive, reverse circulation washing wells and other methods. Works well drilling rigs are pumping reverse circulation type. It works are: the role of atmospheric pressure, the circulating fluid from the settling tank through the return ditch along the annular gap between the wellbore flowing bottomhole HXY-5A-type driver, because the turntable drive drill, drive Rotate drill drilling mud pump suction by the negative pressure of the debris to establish the drill mud suction lumen, then rose to the faucet, the mud pump into the sedimentation tank, circulating fluid continues to flow after precipitation wellbore, so so Again and again, the formation of a reverse circulation drilling work. Buy drilling rigs should be noted that: many types of drilling machines, playing well, then you buy YT series rig, piling hole reverse circulation drilling rig, then you buy, play well, then buy stone impact drill, rock fight, then you buy pneumatic rig, no water, no electricity, fast, 200 meters, 20 hours on it, generally used for air-conditioning Well HXY-5A-type piling machine image, the price is too high, 100,000 yuan is estimated to buy 200 Positive Circulation Drill HXY-5A-type hammers Price, the machine does not fit fieldstone underlying rocks can play HXY-5A-type piling machine parts, 200 meters normally takes 20-30 hours, 200 meters of construction depth is accident-prone sections, Accidents generally up to two percent. HXY-5A-type pile driver where to sell the Prius _ _ Chongqing HXY-5A-type hammers are provided by Luoyang Prius Drilling Equipment Co., Ltd. Luoyang Prius Drilling Equipment Co., Ltd.
