Material and process information of accessories
Hydraulic end: the core of hydraulic power
Fluid End module:
Design and materials: the hydraulic end of the Nov 10-P-130 has a two-piece interchangeable modular steel design. This modular structure has significant advantages, for example, when the suction module is worn, it can be replaced individually without replacing the entire hydraulic end, thus reducing maintenance costs and TIME12. The cylinders are forged from high strength alloy steel 35CrMo, 4130/4135 or AISI 8620 to ensure structural integrity and durability in high pressure and abrasive environments.
Manufacturing process and quality control: the hydraulic cylinder module is manufactured by high pressure forging and heat treatment processes to optimize the mechanical properties of the material to withstand high pressure and impact loads. These processes generally meet or exceed API 7K standards, ensuring the highest quality and reliability of the product.
Valve Assembly (body, seat, spool) :
Key Role: Valve Assembly is the key component of the hydraulic end, high working frequency, large impact, directly affect the service life of the hydraulic cylinder. Nov 10-P-130 is usually equipped with API # 6 valve.
Material and manufacturing process: the body and seat are forged in one piece from high quality alloy steel (20CrMnTi, 40CrNiMo or AISI 8620) . After advanced carburizing and quenching heat treatment, the surface hardness can reach HRC ≥60. The cone surface is precisely ground to ensure high roughness and geometric accuracy, resulting in superior sealing performance.
Valve plug-in materials: standard valve plug-in materials include polyurethane (PU) and nitrile rubber (NBR) , and also provide composite PU and hydrogenated nitrile rubber (HNBR) options to accommodate different drilling fluid properties and temperature conditions.
Bonnet type: Nov 10-P-130 bonnets are usually threaded.
Liners:
Material types: available in high chromium bimetal, zirconia ceramics, alumina ceramics, chrome plated and hardened steel cylinder liners.
Manufacturing process: forging the shell, centrifugal casting the inner sleeve, and honing the inner hole to the mirror finish. Strictly control the dimensional tolerances to ensure easy installation and uniform wear of the cylinder liner, thus extending its service life and optimizing pump performance.
Pistons:
Type: provides integrally vulcanized bonded polyurethane/rubber pistons and replaceable pistons.
Piston core material: piston core is made of forged alloy steel (45 # steel, 40CR or 42CrMo) .
Manufacturing Process: pistons are manufactured by forging and CNC milling, and are surface treated by hardening, tempering, phosphating, and oxidation.
Piston Rods/Pony Rods:
Material: piston rod and intermediate rod made of high strength alloy steel (SAE 4140,42CRMO, 45 # steel, 35CRMO) .
Manufacturing Process: forged, quenched and tempered, precision ground, and surface treated (hard chromium, zinc, or nickel plated) to provide superior fatigue, corrosion, and wear resistance.
Seals and Gaskets:
Commonly used materials: mainly used nitrile rubber (NBR) , hydrogenated nitrile rubber (HNBR) and polyurethane (PU) and other high-quality elastomer materials.
Power End: a solid guarantee for unremitting operation
Main framework:
Structure and materials: the power end of Nov 10-P-130 is made of steel frame. Its base is of one-piece welded construction, and the main bearings and drive bearing housings are of one-piece cast steel. For such heavy machinery, post-weld stress relief treatment is a standard industrial practice to ensure structural stability and long-term reliability and to prevent cracking due to welding stress.
Crankshaft:
Function and material: the crankshaft is made of a whole piece of forged alloy steel with high strength and excellent fatigue resistance. The 4340 material with high nickel content and high chromium content can be selected to reduce crack initiation and corrosion.
Manufacturing Process: the forging process ensures the material's compactness and optimized grain flow, significantly improving its durability under heavy torques and reciprocating loads. The crankshaft is dynamically balanced to ensure the smooth operation of the pump, minimize noise and vibration, thereby extending the life of the bearing and crankshaft itself, and improving the overall reliability of the equipment.
Connecting Rod:
Function and material: the connecting rod is connected by universal joint. Made of high strength alloy steel.
Manufacturing Process: the connecting rod is manufactured by forging process, providing higher dimensional accuracy and improved internal grain flow direction, which is critical for components subjected to heavy periodic loads.
Crossheads and guides:
Function and material: crossheads are usually made of cast steel. Crosshead pins are made of high quality structural alloy steel by one-piece forging. The crosshead slide plate is made of wear resistant manganese bronze guide plate or similar high quality wear resistant material.
Pinion shafts and gears:
Design and materials: the Nov 10-P-130 uses a double herringbone gear train. The gears and shafts are made of integrally hardened alloy steel.
Manufacturing Process: Gears and pinions are hardened by precision forging and heat treatment (carburizing and hardening) and ground to high precision. The application of herringbone gears in mud pumps usually follows or exceeds AGMA standards.
Bearings:
Type and material: double row tapered roller bearings for crankshaft main bearings, self-aligning roller bearings for pinion shaft bearings, cylindrical roller bearings for connecting rod bearings, double row needle roller bearings for crosshead bearings. These bearings are usually made of high quality bearing steel -AISIAISI 52100GCR15Cr15) .
Manufacturing Process: after forging and world-class heat treatment and multi-axis CNC machining to ensure product quality beyond the API standard requirements.
Lubrication system:
Features: The Nov 10-P-130 is equipped with a combination of forced lubrication and splash lubrication to ensure that all moving parts are adequately lubricated.
Optional accessories: to further optimize the lubrication system, we provide optional filters, pressure gauges and oil coolers. Also included is a piston/liner flushing system with a flushing pump, nozzle system, and water tank.
