NOV 14-P-220 Southwest FE Mud Pump

Forging power: uncompromising materials and manufacturing processes

Excellent design must be supported by top-notch materials and manufacturing techniques. For our Southwest hydraulic end modules, every detail reflects the ultimate pursuit of quality.

Top material selection: we specify that all hydraulic end modules are made of high-quality high-strength forged alloy steel, specific brand AISI 4130 or equivalent performance 4135,35CRMO, etc. . These materials are known for their excellent strength, toughness and resistance to fatigue and are ideal for making high-pressure components.

Advantages of forging process: the life of each module begins with a solid steel ingot, forged by a large tonnage press rather than cast. The forging process distributes the flow of grains within the steel along the contours of the component, and the flow of the grains along the contours of the component, this greatly improves its impact resistance, ductility, and fatigue strength -- which are critical to withstanding the hundreds of millions of cycles that mud pumps endure.

Precision computer controlled heat treatment: the forged module will go through a multi-stage, computer controlled heat treatment process (including quenching and tempering) . This process ensures the uniform and ideal hardness and toughness of the module as a whole, which not only ensures the wear resistance of the surface, but also maintains the toughness of the core, thus effectively preventing the generation and propagation of cracks, ensure ultra-long service life.

Advanced Processing and strict quality inspection: the heat-treated module will be precisely machined on the top CNC boring and milling machine to ensure that all dimensional tolerances meet the design requirements. Before leaving the factory, each module must pass stringent quality inspections, including hydrostatic tests up to 1.5 times the working pressure (i.e. 11,250 PSI) , and comprehensive non-destructive testing (NDT) to ensure that there are no internal defects, absolute reliability.

API 7K certification: we solemnly promise that all hydraulic end modules and their components will be manufactured in strict accordance with API 7K specifications. This provides our customers with the highest level of assurance regarding product quality, safety and global interchangeability.

Table 1: hydraulic end core material specification-AISI 4130 low alloy steel

In order to provide technical customers with a transparent and verifiable basis for material properties, the following table details the key technical parameters of AISI 4130 steel. It is these excellent properties that make it the material of choice for the manufacture of the 7500 PSI high pressure hydraulic end.

Cylinder linerーー the first line of defense against wear

We offer two performance classes of liners to meet different operating conditions and budgets.

High chromium bimetallic liners: this is the standard for high performance. It is constructed of a tough forged steel (e. g. Aisi 1045) housing that is tightly coupled to a centrifugally cast high chromium cast iron inner sleeve through an interference fit 17. The high-chromium inner sleeve is heat-treated to a hardness of up to
HRC 60-65, excellent wear resistance. Under standard drilling fluid conditions, its designed service life exceeds 800 hours.

Zirconia ceramic cylinder liner: this is the ultimate solution for extreme conditions such as high abrasiveness, high corrosion and high temperature. It consists of a forged steel case and a solid zirconia ceramic liner. The advantages of the ceramic material are overwhelming: its hardness is close to that of diamond (HRC 90 +) , and it is extremely resistant to abrasives and chemical corrosion. Its mirror-like smooth inner wall also significantly reduces friction with the piston, extending piston life. Although the initial investment is high, the
An extended life of 2,000 to more than 4,000 hours will significantly reduce total cost of ownership by significantly reducing downtime for maintenance.

The purpose of this table is to help customers make the most cost-effective choice based on specific operating conditions.

3.2 piston-a reliable seal at extreme pressures

We offer the 14P-220 with a high performance bonded piston designed to meet the most demanding challenges.

Piston core: Made of high-strength forged steel or high-quality metal material to provide a strong structural framework and prevent deformation or failure under high pressure.

Sealing body: using special formula, high temperature resistant polyurethane material, through the chemical bonding process and piston core firmly together. This advanced polyurethane material is remarkably resistant to abrasives, chemicals, and high-pressure extrusion in water-and oil-based drilling fluids, ensuring a reliable, durable seal throughout the life of the fluid.

Manufacturing Process: the piston core is formed by forging or investment casting followed by precision CNC machining to ensure perfect fit dimensions and concentricity to maximize sealing performance and life.

3.3 valves and seats-the gateway to high pressure performance

14P-220 using API Mod. 8 full open valve assembly, the industry standard for this class of pump.

Design: the"Full Open" design provides the maximum flow area, effectively reducing the turbulence and pressure loss when drilling fluid flows through the valve port, thereby improving the volumetric efficiency of the pump.

Valve rubber: the core of the valve assembly is a replaceable polyurethane valve rubber. Designed for high pressure (7500 PSI) and high temperature (up to 220 ° F/104 ° C for standard models and higher for special formulations) , it has excellent wear and impact resistance and can maintain a reliable positive seal over millions of cycles.

Seat: the seat is forged of high-strength alloy steel and specially heat-treated to resist erosion and wear of high-flow drilling fluid, providing a stable and durable sealing surface for the valve rubber.

3.4 piston rod-strong arm for power transfer

Material and fabrication: the piston rod is forged from high strength alloy steel (e. g. 35CRMO or AISI 4140) and integrally heat treated for optimum combined mechanical properties, particularly fatigue strength.

Surface treatment: the surface of the piston rod by advanced coating treatment, usually hard chromium plating or similar NI-CR composite coating. The coating provides an extremely high surface hardness (e. g. HB220-260) , an extremely low coefficient of friction, and excellent corrosion resistance, providing an ideal operating surface for packing seals, thus maximizing the life of the seal and preventing wear of the piston rod itself.

Connection structure: precision machined thread and guide shoulder connection design ensures a safe and reliable metal-to-metal locking between the piston rod and the intermediate pull rod, effectively prevents loosening in severe reciprocating motion.

Power end-a solid foundation for durability

Welded steel frame: the frame is welded with thick steel plates after complete stress relief treatment, providing an extremely strong and stable foundation for all moving parts. This ensures that the alignment accuracy of key components is maintained at maximum load, thereby reducing abnormal wear.

Herringbone Gear Excellence: this is the 14P-220 power side of a big bright spot.

Design: adopt"Wide face" or"Continuous tooth" herringbone gear transmission system.

Core advantage: unlike spur or single helical gears, double helical gear structure in meshing axial force generated will offset each other, so the axial thrust is zero.

Materials: large and small gears are machined from high strength alloy steel forgings and are integrally quenched for maximum durability and load carrying capacity.

Robust drivetrain and bearings:

Crankshaft: a massive, monolithically forged alloy steel crankshaft provides unparalleled strength and fatigue resistance, as well as the ability to deliver 2200HP of power.

Bearings: complete set of heavy duty bearings designed for extreme conditions: including two double row tapered roller main bearings, two self aligning roller pinion shaft bearings, and premium cylindrical roller and needle bearings for connecting rods and crossheads. This configuration is designed to handle the large radial and axial loads associated with the 2200HP input power.

Reliable lubrication system: the use of mature and reliable dual lubrication system, a combination of forced lubrication and splash lubrication. A forced lubrication system driven by a built-in oil pump delivers clean oil directly to critical bearing and crosshead slideway surfaces, while splash lubrication covers other moving parts, this ensures complete and continuous lubrication protection of the entire power end. At the same time, the independent spray system continuously provides cooling and lubrication for the cylinder liner and piston contact surface, effectively extending its service life.
