Work drilling machine is 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 flow to the wellbore bottom, because the turntable drive drill, drill drive rotation of drilling, established by the mud pump suction vacuum the debris drill mud suction lumen, then rose to the faucet, the mud pump into the sedimentation tank, circulating fluid after precipitation 150 meters continue to flow into the well bore drilling machine manufacturers, so so Again and again, the formation of a reverse circulation drilling work. Mud or water from the drill pipe into the outflow from the wellhead. Positive circulation drilling machine. Mud or water from the drill pipe sucked out from the wellhead inflows. For the reverse circulation drilling machine. Refers to reverse circulation drilling fluid (mud or water) in the drilling machine cycle ways to say, the drilling machine drill drilling time will have to produce sediment, slag stone, by reverse circulation can take the mud these scum to the ground, and then through the mud after the settler back to drilling. Thus, the continuous cycle, and finally into the hole. Reverse circulation can bring a larger diameter slag. Drilling machine Step Step 1: Configure the appropriate pump into the well during drilling drainage construction according to the situation, found the movement of water wells and the corresponding amount of water, and then ground to move water level elevation and irrigation you used mode, the pump work required to determine the total head lift pump, pump flow rate must not exceed the water flow of the well, from the above two conditions, the purchase of the corresponding pump. Step two: location rational layout of the borehole to borehole layout reasonable layout based on the actual local hydrogeological situation, no hydrogeological data can be referred to as a nearby water wells has been well arranged basis. Not abundant in shallow groundwater areas must not blindly hit shallow; rich in shallow groundwater areas 150 meters drilling machine production line, suitable for peasant self-built shallow drilling machine works 150 meters, but also the well hole layout not too close, to avoid interactions between adjacent water wells. The third step: using the correct construction method of construction method, there are two large wells: one big slot, artificial excavation or blasting construction; the second is open caisson method, and drainage or drainage construction. Counterpart pumping construction, general mechanical and manual lifting hammer hammer hanging two methods, the use of gravity will drop hammers suction tube directly into the ground. 150 m drilling machine manufacturers _ Prius _150 meters drilling machine provided by Luoyang Prius Drilling Equipment Co.
