slurry pump performance by what factors

slurry pump is also a general concept of a wide range of pumps, different areas, habits, and ultimately the pump type will not be the same, the term described in the mud pump is the most sense of a pump type: oil drilling field Of the applied mud pump.
The two main parameters of mud pump performance are displacement and pressure. Displacement is calculated at several liters per minute. The larger the pore size is, the greater the displacement required to calculate the diameter of the drilling fluid and the required flushing fluid from the bottom of the hole. The return speed of the rinse solution is required to allow the cuttings of the drill bit to be washed away from the bottom of the hole and to carry it to the surface. Geological core drilling when the general return speed of 0.41 m / min or so. The pressure of the pump depends on the resistance of the passage through the depth of the drilling fluid and the nature of the flushing fluid. The deeper the drilling resistance, the greater the pressure required. As the depth of the borehole diameter changes, the displacement of the pump can be adjusted at any time. In the pump mechanism is equipped with a gearbox or a hydraulic motor to adjust its speed  to achieve the purpose of changing the displacement. In order to accurately grasp the pump pressure and displacement changes in the mud pump to install the flow meter and pressure gauge at any time so that the drilling staff to understand the operation of the pump through the pressure changes to determine whether the normal state of the hole to prevent the occurrence of hole accidents.
