Horizontal directional drilling mud pump refers to a machine that delivers flushing fluid such as mud or water to the borehole during the drilling process. Mud pump is an important component of drilling equipment.
The horizontal directional drilling mud pump is used in a positive circulation drilling well. The surface flushing medium - clear water, mud, or polymer flushing fluid - is directly sent to the bottom of the drill bit under a certain pressure through a high-pressure hose, faucet, and the center hole of the drill string, achieving the purpose of cooling the drill bit, removing drilling debris, and transporting it to the ground.
Commonly used mud pumps are piston or plunger type, where the crankshaft of the pump is driven by a power machine to rotate, and the crankshaft drives the piston or plunger to move back and forth in the pump cylinder through a crosshead. Under the alternating action of the suction and discharge valves, the purpose of pumping and circulating flushing fluid is achieved. The pressure of the horizontal directional drilling mud pump depends on the depth of the borehole, the resistance of the channel through which the flushing fluid passes, and the properties of the flushing fluid conveyed. The deeper the borehole, the greater the pipeline resistance and the higher the required pressure.
As the diameter and depth of the borehole change, it is required that the displacement of the horizontal directional drilling mud pump can be adjusted at any time. In order to achieve the purpose of changing the displacement, a gearbox is installed in the pump mechanism or its speed is adjusted through a hydraulic motor. In order to accurately grasp the changes in pump pressure and displacement, a flow meter and pressure gauge should be installed on the mud pump, so that the driller can understand the operation and rotation of the pump at any time. At the same time, the pressure changes can be used to determine whether the situation in the hole is normal and prevent accidents in the hole.
During the construction process, the mechanical and horizontal directional drilling mud pump can continuously work normally, allowing the mud pump to achieve high work efficiency. Therefore, it is necessary to have a reasonable schedule and strict management system in order for sampling to play its role.
