Hydraulic end: the core of hydraulic power

Hydraulic end module:

Design and material: the hydraulic end is an l-shaped, two-piece design designed for high-pressure systems. The module is manufactured by high-pressure forging process and subjected to world-class heat treatment, fully meet or even exceed the API 6A specification requirements. For 5000 PSI applications, Aisi 4130(30CrMo) alloy steel is generally used to ensure its structural integrity under extreme stress. The three cylinders of the hydraulic end module are interchangeable, improving ease of maintenance.

Valve Assembly (body, seat, spool) :

Key Role: Valve Assembly is the key components of the hydraulic end, high working frequency, impact force. Its quality directly affects the service life of the hydraulic cylinder, and it is one of the main vulnerable parts of the mud pump. It controls the suction and discharge of drilling fluid to ensure the continuous circulation of drilling fluid in the rig.

Material and manufacturing process: valve body and seat are made of high quality alloy steel 20CrMnTi, which is higher than petroleum industry standard. Through advanced carburizing and quenching heat treatment process, the product obtained high strength and high toughness, work surface hardness to HRC60.

Design variety: valve assemblies can be divided into 4-wing, 3-wing, and full open valve assemblies depending on the seat bore.

Bushings:

Material and manufacturing process: the mud pump bushing combines the strength of a forged steel casing with the wear and corrosion resistance of a high chromium cast iron or zirconia ceramic lining. The inner sleeve is made of centrifugally cast high chromium iron or 99.99% zirconia ceramic. After precision machining and heat treatment, the minimum uniform pore hardness reaches HRC65.

Piston:

Materials and manufacturing process: piston assembly is an important spare parts and wear parts of oil drilling mud pump. The piston hub is usually forged of high hardness alloy steel (45 # steel or 40CR) . The cup is made of polyurethane or rubber.

Advantages: these piston designs offer high tensile strength, maximum operating temperatures up to 250 °F, and the advantage of extended service life.

Piston rod/intermediate rod:

Material and manufacturing process: the piston rod is the main component connecting the power end and the hydraulic end, and is responsible for transmitting power. They are forged from high quality alloy steel, commonly used materials include SAE 4140,42CRMO or 42CRMO4.

Performance improvements: hard chromium plating significantly improves the wear and corrosion resistance of the piston rod and provides a smooth surface. In addition, surface treatments such as zinc or nickel plating are available to meet the varying needs of customers.

Seals and gaskets:

Materials: seals and gaskets (including bushing gaskets and piston replacement rubber) are essential to maintain pressure integrity and prevent leaks. They are made from durable materials such as nitrile rubber (NBR) , hydrogenated nitrile rubber (HNBR) and polyurethane (PU) . These materials are selected to ensure long-term effective sealing in high-pressure, abrasive fluid environments in mud pumps.

Power End: the solid guarantee of unremitting operation

Main framework:

Design and materials: the power end is fabricated from precision machined structural steel for the main frame, constructed through welding and stress relief processes. This design ensures strong support and stability for all internal components.

Crankshaft:

Function: the crankshaft converts the reciprocating linear motion of the piston rod into rotary torque to drive the mud pump.

Material and manufacturing process: the crankshaft is made of high quality alloy steel castings, especially 4340 alloy steel with high nickel content. This material selection is essential to prevent crack initiation and propagation, while providing superior corrosion resistance.

Connecting Rod:

Function: the connecting rod connects the piston to the crankshaft, converting reciprocating motion into rotary motion.

Material and manufacturing process: the connecting rod is made of alloy steel. They are manufactured by a forging process that provides higher dimensional accuracy and improved internal grain flow direction, which is essential for components subjected to heavy periodic loads.

Crossheads and guides:

Function: the crosshead connects the piston rod and guides the reciprocating motion of the piston.

Materials and manufacturing process: crossheads are usually made of ductile iron, while crosshead pins are made of high-quality structural alloy steel.

Pinion shafts and gears:

Design: DRILLMEC 12T1600 mud pump with double helical pinion shaft and large gear system.

Materials and manufacturing processes: Gears and pinions are manufactured from forged grade steel which is fully deoxidized and homogenized and subjected to secondary refining including vacuum degassing.

Performance advantages: net-formed gear teeth provide higher strength, longer life, improved power density and consistent quality. These characteristics ensure the high efficiency and reliability of the transmission system under heavy load and high speed operation.
