3. Mud Pumps Drilling fluid, or mud, is essential for lubricating the drill bit, stabilizing the borehole, and transporting cuttings to the surface. Mud pumps are used to circulate this drilling fluid through the drill string and back to the surface. The efficacy of the mud system can significantly influence drilling efficiency and safety.

Before delving into calculations, it's key to understand how a mud pump operates. Most modern drilling rigs use either triplex or duplex pumps, which use a series of pistons to create pressure. The fluid is drawn into the pump from a storage tank and pumped down the drill string. After reaching the drill bit, the mud carries cuttings back up to the surface through the annulus (the space between the drill string and the wellbore).

Due to the machine's working environment being prone to intense vibrations and impacts, constantly observe the dynamics of various parts during operation. If you detect abnormal noise or other irregularities, shut down the machine immediately for inspection and repair before resuming operation. If hydraulic system connectors leak or components become loose, shut down the machine for adjustment and tightening. After ensuring everything is normal, you can resume operation. Before completing each shift, lower the hydraulic hammer to the lowest position and retract all other hydraulic cylinders to their shortest length. If moving a distance, keep the mast leaning backward. For the machine's components, accessories, and electrical equipment, perform regular inspections, especially the connections in the wiring of the motor. During operation, there should be designated personnel for guidance. The guide and the operator should check signals with each other before work and cooperate closely. At the start, use a bell or other methods to signal and inform surrounding personnel to move away. The machine should start at a low speed and gradually accelerate to high speed.
