Mud Pump is an very important tools used for mining and drilling. When to select which mud pump is more suitable for your work, the following two elements should be taken in to consideration.
1. Displacement
To determine performance of the mud pump we should check the displacement first. The displacement is calculated at several liters per minute, which is related to the diameter of the borehole and the required flushing fluid from the bottom of the hole, ie the larger the pore size, the greater the required displacement. The rewinding speed of the rinsing fluid is required to cut the cuttings of the drill bit, and the rock powder is washed away from the bottom of the hole and 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 borehole, 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. In order to accurately grasp the pump pressure and displacement changes, the mud pump to install the flowmeter and pressure gauge, at any time 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 condition to prevent the occurrence of holes accident.
