Work drilling machine is pumping reverse circulation type. Its working principle is: the role of atmospheric pressure, circulating liquid from the settling tank through the return ditch along the annular gap flow to the bottom of the borehole, when the turntable drive drill, drill drive rotation of drilling by the mud pump the establishment of a negative pressure suction debris drill mud suction lumen, then rose to the faucet, the mud pump into the sedimentation tank 200 drilling machine production line, the circulating fluid continues to flow after precipitation wellbore, again and again, forming a reverse circulation drilling work. Prius production after years of research practice, according to the construction requirements of 200 drilling rigs Price, business-to-well drilling rig conducted a number of improvements to make products increasingly perfect, I have a reasonably well drilling rig structure, economic and durable, easy to operate, mechanical high efficiency, wide application, low maintenance, easy maintenance and other characteristics, by domestic and foreign customers of all ages.

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 200 drilling machine, speed, 200 meters 200 drilling machine how much money, 20 hours on it, generally used for air-condition well, the price is too high, an estimated 100,000 yuan being able to buy a 200 circulation drill, the machine does not fit loose stone on the ground floor can play rock, 200 meters normally takes 20-30 hours, 200 meters of construction depth is accident-prone sections of up to two percent of accidents in general. 200 drilling machine picture _ Prius _200 type drilling machine provided by Luoyang Prius Drilling Equipment Co., Ltd.
