Pressure
The pressure size of the pump depends on the depth of the drilling hole, the resistance of flushing fluid (drilling fluid) through the channel, as well as the nature of the conveying drilling fluid. The deeper the drilling hole and the greater the pipeline resistance, the higher the pressure needed.
With the changes of drilling hole diameter and depth, it requires that the displacement of the pump can be adjusted accordingly. In the Mud Pump mechanism, the gearbox or hydraulic motor is equipped to adjust its speed and displacement. In order to accurately grasp the changes in pressure and displacement, a flowmeter and pressure gauge are installed in the Mud Pump.
