Mud Pump

• Mud pumps, refers to the process of drilling to transporting mud or water in the drilling fluids, such as oil machinery. Mud pump is an important part of drilling equipment.
  Commonly used in normal circulation drilling, it is surface wash medium-mud or polymer drilling fluid in water system, a certain amount of pressure, through high-pressure hoses, taps and string centre hole bottom of the drill bit directly, in order to cool the drill bit, cutting down of debris removal and the purpose of conveying to the surface.
  Common is a piston or plunger mud pump, driven by the engine crankshaft rotation of the pump, crankshaft through cross driven piston or reciprocating piston in the pump cylinder. Under the alternating effects of suction and discharge valves, achieve the purpose of pressure and flushing liquid.
  
  
  Two main parameters of slurry pump for displacement and pressure.
  Displacement calculated in discharged number of litres per minute, it and the hole diameter and the required washing fluid upward velocity of hole bottom, that is, the larger the required displacement greater. Required washing fluid upward speed of cutting down the drill cuttings, and rock dust rushing away from the hole, and carried to the surface in a reliable way. When the geological core drilling, usually at a rate of return in approximately 0.4~1.0 m/min.
  
  
  Pump pressure depends on depth of drilling, washing liquid after passage of the nature of resistance, as well as the transmission fluid. Drilling deeper, larger pipeline resistance required higher pressure.
  Along with the drill diameter, depth changes required pump displacement can be adjusted at any time. The pump body is provided with gearbox or hydraulic motor to adjust its speed to achieve change in emissions objectives. In order to accurately grasp changes of pressure and displacement pumps, flow meters and pressure gauges to be installed on the pump, keeping drilling pumps shipped \ turned to those situations, and through pressure changes distinguish whether the hole normal to prevent accidents inside the hole.
