Is in the process of drilling mud to the drilling mud or water transmission fluid machinery. Drilling mud is an important part of extrusion line equipment. Its main role is in the drilling mud during the process of drilling with the drill bit into the hole, play a bit cool, clean hole, fixing shaft, drive drilling, and drilling cuttings back to the ground after the role. Are in common circulation drilling, the mud is to the surface water circulation medium ─ ﹑ mud or polymer fluids in certain pressure, through high-pressure hose taps and drill column ﹑ direct-drill the center hole at the bottom, in order to achieve ﹑ will cut down the cooling drill cuttings removal and transport to the surface of the goal. Mud is a common type or plunger-type piston, driven by the power machine rotary pump crankshaft, crankshaft driven by the crosshead and then the plunger in the pump cylinder piston or reciprocating motion to do. Suction and discharge valves in alternation, to achieve pressure fluid delivery and recycling purposes.
