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, circulating fluid continues to flow after precipitation wellbore, again and again, forming a reverse circulation drilling work . Buy drilling rigs should be noted that: many types of drilling machines, playing well, then you buy 150 meters drilling rig YT series machine works, piling holes, then bought 150 meters of reverse circulation drilling rig drilling machine how much money or play rock Well, then you buy the impact of drilling, rock fight, then you buy a pneumatic drill, no water, no electricity, speed 150 m drilling machine image, 200 meters, 20 hours on it, generally used for air-condition well, is price is too high, 100,000 yuan is estimated to buy 200 positive circulation drill, the machine does not fit loose stone on the ground floor can play rock, 200 meters normally takes 20-30 hours 150 meters drilling rigs, construction depth is 200 m accident-prone sections of up to two percent of accidents in general. We have a lot of time to introduce our simple form structure drilling machines, but people still do not understand, then you summarize for everyone again about it. Drilling machine structure: Trailed, vehicle type, vehicle back machine type. The composition of the general drilling machine: diesel engine, friction clutch, transmission, transfer case, drive shaft, mud pump, water pump, vacuum pump, turntable, faucets, winches, hydraulic systems, steering mechanism, the mast, drill, trailers and other . 150 m drilling machine manufacturer | Liaoning 150 meters drilling rigs | Prius Prius provided by Luoyang Drilling Equipment Co., Ltd.
