Structured Product Description

Product Introduction

This comprehensive lineup covers lubrication pumps, precision bearings, mud pump wear parts, hydraulic valves, and sealing components, headlined by flagship models: VIKING HJ475 external lube pump, NSK NJ216ET/NJ2213.W/NJ2216.W bearings, F-16 HL mud pump valve/seat assemblies, and DBDS10K1X/100 plug-in relief valve. Each part is fabricated from high-performance materials: hardened bearing steel for NSK bearings, wear-resistant nitrile rubber for SOG oil seals, high-pressure diaphragm composites for lube pumps, and corrosion-resistant alloys for mud pump components. All products undergo strict pressure testing, wear testing, and tolerance inspection to ensure seamless, modification-free installation on original drilling and hydraulic equipment.

Function Description

• Lubrication Pump Components: The VIKING HJ475 external lube pump provides consistent pressurized lubrication to rig rotating parts; E17-152 diaphragm protection assemblies prevent pump damage from contaminants, ensuring stable lubrication flow.

• Precision Bearings: NSK NJ series cylindrical roller bearings handle heavy radial loads and high-speed rotation for rig gearboxes and pump shafts, reducing friction loss by 25% and minimizing heat buildup during continuous operation.

• Mud Pump Sealing & Wear Parts: Custom-sized cylinder seals, valve springs, and wear plates for F-16 HL/HHF-1600HL/QYB42-125L mud pumps create zero-leak sealing, resist abrasive drilling mud wear, and maintain consistent mud pressure output.

• Hydraulic Control Valves: Fixed-flow control valves, shuttle valves, and DBDS10K1X/100 relief valves regulate hydraulic pressure and flow for YZ.100S-096 disc brake HPUs, preventing pressure spikes and ensuring stable brake operation.

• Sealing & Auxiliary Parts: SOG TC oil seals and O-rings block gear oil/hydraulic fluid leaks; retaining rings and accumulators stabilize hydraulic system pressure and secure filter components.

Structure Characteristics

• Premium OEM Precision Tolerance: Critical bearing, seal, and valve surfaces hold ±0.008mm dimensional accuracy, guaranteeing perfect alignment with VIKING HJ475 pumps, F-16 HL mud pumps, and YZ.100S-096 HPUs.

• Extreme Wear & Corrosion Resistance: NSK bearings feature case-hardened steel for long-lasting durability; mud pump seals use oil-resistant rubber compounds to withstand abrasive drilling mud and hydraulic fluid exposure.

• Modular Plug-and-Play Design: Seal kits, valve cartridges, and bearing assemblies use modular construction, cutting on-site replacement time by 36% compared to custom-fabricated parts.

• High-Pressure Compatibility: Hydraulic valves and mud pump seals are rated for up to 350 bar working pressure, matching the strict demands of high-load drilling and hydraulic brake systems.

Applicable Operating Conditions

These components are engineered to perform reliably in extreme oilfield and industrial drilling environments, including:

• Onshore/offshore drilling rigs (mud pump systems, gearboxes, and external lubrication circuits)

• YZ.100S-096 disc brake hydraulic power units (high-pressure hydraulic control)

• F-16 HL/HHF-1600HL/QYB42-125L triplex mud pumps (abrasive mud circulation, continuous heavy-load operation)

• VIKING HJ475 external lubrication systems (pressurized oil delivery for rotating rig components)

• Temperature range: -40℃ to 130℃, pressure range: up to 350 bar, suitable for continuous heavy-duty drilling operations

Maintenance & Care Recommendations

• Lubrication Pump Maintenance: Inspect the VIKING HJ475 pump diaphragm and inlet joint every 200 operating hours; clean filter screens quarterly to prevent clogging; replace worn diaphragm assemblies to maintain lubrication pressure.

• Bearing & Seal Care: Lubricate NSK NJ series bearings with high-temperature lithium grease every 400 hours; inspect SOG TC oil seals for cracks/hardening monthly; replace worn seals immediately to prevent fluid leaks.

• Mud Pump Upkeep: Check valve springs, wear plates, and cylinder seals every 300 hours; replace worn mud pump components to avoid pressure loss and fluid leaks; flush mud circuits quarterly to remove sediment.

• Hydraulic Valve Maintenance: Calibrate relief and flow control valves semi-annually; inspect valve cartridges for wear quarterly; replace faulty valves to maintain stable hydraulic pressure.

• Storage Guidelines: Store parts in a dry, dust-free, ventilated area; retain original packaging to prevent corrosion, deformation, and contamination of precision components.

On-Site Fault Repair Cases

Case 1: F-16 HL Mud Pump Fluid Leakage

An F-16 HL mud pump experienced severe mud leakage and pressure drop due to worn AH160201-0116B4 cylinder seals and damaged valve seats. Replacing the OEM-matched cylinder seals and AH000002-0902B1 valve seats restored full pressure and eliminated leaks, resuming drilling operations within 2 hours.

Case 2: Rig Gearbox Bearing Failure

A drilling rig gearbox suffered abnormal noise and overheating due to a faulty NSK NJ2216.W bearing. Installing a new genuine NSK NJ2216.W-JPN bearing and matching TC 90X120X12 SOG oil seal resolved the overheating issue, restoring smooth gearbox rotation and extending component life.Case 3: YZ.100S-096 Brake HPU Pressure SpikeA YZ.100S-096 disc brake HPU experienced dangerous pressure spikes due to a malfunctioning DBDS10K1X/100 plug-in relief valve. Swapping the faulty valve for a new OEM-spec unit stabilized hydraulic pressure, preventing brake damage and ensuring safe rig operation.
