Drilling machine has a very important role in the exploration industry, and for customers who require drilling rigs, drilling rigs in the choice of the time, the quality is the most important. So what kind of drilling machine is has the quality of it? First, the drilling machine parts must guarantee quality, without these parts, then the device is not properly run. And if a company choose inferior parts in the use of spare parts, then the overall quality will decline. This will not protect the life and the work efficiency of the drilling machine.

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 350 faucet drilling machine manufacturer, the mud pump into the sedimentation tank 350 drilling machine, circulating liquid precipitation continues into the well bore, so again and again, forming 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. 350 drilling machine price, the Prius, Chongzuo 350 drilling rigs provided by Luoyang Prius Drilling Equipment Co., Ltd.
