The Importance Of Controlling The Displacement And Pressure Of Oil Drilling Mud Pump
May 05, 2017

 Displacement and pressure are two important factors that affect the performance of oil drilling mud pumps. In the mud pump drilling operation, the operator needs to accurately control the pressure and displacement of the pump. The mud pump should be equipped with a flowmeter and pressure gauge. So that the drilling staff to understand the pump to transport the situation, while the pressure changes through the hole to determine whether the normal situation to prevent the occurrence of hole accidents.

   1.Displacement: Calculated at several liters per minute, it is related to the diameter of the borehole and the required flushing fluid from the bottom of the hole, the larger the pore size, the greater the required displacement. Requires the return of the rinse liquid to cut the drill bit down the cuttings, rock powder and timely washed away from the bottom of the hole, and reliably carried to the surface. Geological core drilling, the general return speed of 0.4 to 1.0 m / min or so.

   2. Pressure: The pressure of the pump depends on the depth of the drill, the resistance of the passage through which the rinsing solution passes, and the nature of the flushing fluid being conveyed. The deeper the drilling, the greater the resistance of the pipeline, the higher the pressure required. With the drilling diameter, depth changes, the displacement of the pump can be adjusted at any time. In the pump mechanism is equipped with gearbox or hydraulic motor to adjust its speed, in order to achieve the purpose of changing the displacement.
