Product Description MUD PUMP Mud Pump, or mud pump in its abbreviated form, serves as a generalized term for a variety of pumps, with specific pump types varying across different regions and practices. Below is a brief introduction to mud pumps, primarily focusing on the type commonly used in oil drilling:OverviewMud pumps are mechanical devices designed to deliver mud, water, or other flushing fluids into drilling holes during drilling operations. They constitute an essential component of drilling machinery and equipment.FunctionThe primary role of mud pumps in the drilling process is to inject mud into the wellbore along with the drill bit. This mud serves several purposes:Cooling the Drill Bit: The mud helps to dissipate heat generated by the drill bit, preventing overheating and ensuring smooth drilling operations.Cleaning the Drilling Tools: The mud washes away cuttings and debris generated during drilling, maintaining a clear pathway for the drill bit.Stabilizing the Wellbore: The mud helps to stabilize the wellbore walls, preventing cave-ins and ensuring the structural integrity of the drill hole.Driving the Drilling Process: The pressure and flow of the mud can also assist in driving the drill bit forward.Returning Cuttings to the Surface: The mud carries the drill cuttings back to the surface, allowing for their removal and disposal.Operating PrincipleIn typical positive-cycle drilling operations, mud pumps deliver flushing media such as water, mud, or polymer flushing fluid under a certain pressure. These fluids are then transported through high-pressure hoses, taps, and the center hole of the drill string to the bottom of the drill bit. This process achieves the dual purpose of cooling the drill bit and removing and transporting drill cuttings to the surface.Mud pumps commonly used are of the piston or plunger type. Powered by a motive force, the crankshaft of the pump rotates, driving the crosshead and subsequently causing the piston or plunger to reciprocate within the pump cylinder. The alternating action of the suction and discharge valves facilitates the delivery and recycling of flushing fluids.In summary, mud pumps are crucial for ensuring the efficiency and safety of drilling operations. Their ability to deliver flushing fluids under pressure enables them to play a pivotal role in cooling, cleaning, stabilizing, and advancing the drilling process.FORGING WELDING OF THE CRANKSHAFT IMPROVED MECHANICAL PROPERTIES,BALANEING IMPROVE TypeHorizontal triplex single-acting piston pumpGear typemandibular toothRated Input Power(kW/hp)1193/1600Gear ratio4.206:1Rated strokes (strokes/minute)120OilyForced , splashStroke length(mm/in)305/12''Valve cavityAPI-7#Suction port connection size12''(305mm)Discharge outlet connection size5''Mainframe weight (kg)24791Overall Dimension(L×W×H)4615×3276×2688mm Pump speed (strokes/min)Rated Power(HP)Cylinder Liner Diameter (in) and Rated Pressure (Mpa)/(psi)72006/3/42006/1/462005/1/2524.1925.4629.6632.1634.535350836924300466350005075engine displacement (L/S)/(g pm)120160045.4142.2336.233.3628.0423.17720669574529444367110146741.6338.7133.1930.5825.721.24660614526485407337100133337.8435.1930.1727.823.3619.3160055847844137030690120034.0631.6727.1525.0221.0317.385405024303973332751 0.37840.35190.30170.2780.23370.193165.57784.77784.41113.73.0556Volumetric efficiency at 100%, mechanical efficiency at 90%
