A brief introduction to the mud pump

Jul 27, 2017

Mud pump, refers to the drilling process to the drilling of mud or water and other washing fluid delivery machinery. Mud pumps are an important part of drilling equipment.


In the commonly used circular drilling, it is the surface rinse medium ─ ─ water, mud or polymer rinse liquid under a certain pressure, through the high-pressure hose, faucet and drill rod center hole directly to the bottom of the drill to achieve Cooling the drill bit, cutting the cuttings down and conveying them to the surface.

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.

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
