What are the main factors affecting the performance of mud pump? Let's introduce it to you.
1、 The displacement is calculated by discharging several liters per minute, which is related to the diameter of the borehole and the required speed of the flushing fluid returning from the bottom of the borehole. The larger the aperture is, the larger the displacement is. Request the upward return speed of the flushing fluid to flush the rock cuttings and rock powder cut by the drill bit away from the hole bottom in time and firmly carry it to the surface. During geological core drilling, the general upward velocity is about 0.41 M / min.
2、 The pressure of the pump depends on the depth of the borehole, the resistance of the channel through which the flushing fluid passes, and the nature of the flushing fluid. The deeper the borehole, the greater the resistance, and the higher the pressure required. With the change of borehole diameter and depth, the displacement of the pump can be adjusted at any time. A gearbox is arranged in the mechanism of the pump or its speed is regulated by a hydraulic motor. In order to achieve the purpose of changing the displacement. In order to accurately control the change of pump pressure and displacement, a flowmeter and pressure gauge shall be installed on the mud pump to make the drilling personnel understand the operation condition of the pump at any time, and judge whether the situation in the hole is normal through pressure change, so as to prevent accidents in the hole.
The above is a small series for you to introduce the main factors affecting the performance of the mud pump, I hope you can understand.
