Mud pumps need to be noted during drilling

Mud pump is in the drilling process, to the drilling of mud or water and other washing fluid machinery. Mud pumps are an important part of drilling machinery and equipment. Its main role is in the drilling process with the drill bit into the drill down with the drill bit, plays a cooling bit, cleaning the drilling tool, fixed the borehole wall, drive drilling, and drilling drill back to the ground role.
In the commonly used circular drilling, the mud pump is the surface of the rinse medium - water, mud or polymer rinse liquid under a certain pressure, through the high pressure hose, faucet and drill pipe column hole directly to the bottom of the drill to achieve Cooling the drill bit, the cutting down the cuttings and transport to the surface of the purpose.
Commonly used mud pump is piston or plunger type, driven by the power machine crankshaft crankshaft crankshaft through the cross head and then drive the piston or plunger in the pump cylinder to do reciprocating motion. In the inhalation and discharge valve under the alternating effect, to achieve the purpose of pressure and circulation rinse solution.
Mud pump is a kind of pump product, its performance in the two main parameters is the displacement and pressure, the displacement is calculated in several liters per minute, it with the drilling diameter and the required rinse from the bottom of the hole Back to the speed, that is, the larger the aperture, the greater the required displacement. Requires the rinsing fluid to return the speed of the drill bit can be cut 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 m / min or so.
And the pressure of the mud pump depends on the size of the drilling, flushing fluid through the resistance of the channel and the nature of the washing fluid. The deeper the drilling, the greater the resistance of the pipeline, the higher the pressure required. With the drilling diameter and 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.
Finally, in order to accurately grasp the pump pressure and displacement changes, you can install the flowmeter on the mud pump and pressure gauge, at any time so that the drilling staff to understand the operation of the pump, while the pressure changes through the hole to determine whether the normal condition to prevent the occurrence of holes Internal accident.
