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 wells 70 meters machine image, the negative pressure of the mud pump suction debris build drill mud suction lumen, then rose to tap into the sedimentation tank by slurry pump 70 meters drilling machine, circulating fluid continues to flow after precipitation wellbore, 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, speed 70 m drilling machine manufacturer, 200 meters, 20 hours on it, generally used for air-condition well, the price is too high, 100,000 yuan is estimated to buy 200 n 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. Drilling machine Installation Notes 1. Install the front rig, should have exploration data, geological conditions and confirm compliance with the requirements of the aircraft, no laying underground thing, no obstructions within the operating range, a safe distance from the construction site and overhead transmission lines to meet the requirements . 2. Drill installation site should be flat, solid, able to carry the machine to work under pressure; adverse local group, under the rig should Overlay steel protection. 3. 70 meters drilling rig installed machine how much money should be in professional and technical personnel under the command. Installation personnel must be trained, familiar with the installation process and command signals, and to ensure the safety of technical measures. 4. rig matches cranes, piling required should be based on the height and weight to choose. 5. The introduction of lighting power units should be installed low voltage transformers, voltage should not exceed 36V. Should not be used (liquid, gas) powered winches and cranes and other lifting equipment lifting people up and down. Lifting equipment should not exceed the load work. 70 m drilling machine production line, the Prius preferred, Zhejiang 70 m drilling machine provided by Luoyang Prius Drilling Equipment Co., Ltd.
