Backed by strict dimensional verification and material certification, every part delivers a 99.5% OEM fitment rate and 30% longer wear life than generic alternatives, fulfilling the core user demand for reliable, standards-compliant, quick-install replacement parts that reduce maintenance labor costs, eliminate costly shutdowns, and keep critical equipment operating at peak efficiency.

Detailed Product Description

Product Introduction

This comprehensive portfolio includes over 45 mission-critical spare parts spanning filtration, sealing, transmission, hydraulic control, structural, and electrical categories — featuring flagship models like the 1R0726 oil filter, DB20-1-50/315 relief valve, PJ08108-AC-0032 gear casing seal kit, and 7645-0081 limit switch valve kit. Each component is manufactured from high-grade industrial materials (heat-treated alloy steel, wear-resistant fluororubber, high-efficiency filter media) and complies with international standards including GB3761, GOST 9740-71, and API drilling specifications. All parts undergo 100% pressure testing and dimensional inspection, ensuring seamless integration with original equipment without modification.

Function Description

• Filtration Components: Oil filters (1R0726), return oil filters (KMCL-3Y04), and pre-filter cartridges (57413750) remove metal shavings, sediment, and contaminants from hydraulic oil and lubricants, reducing component abrasion and extending fluid life by 25%.

• Hydraulic Control Parts: DB20-1-50/315 relief valves stabilize system pressure up to 315 bar; limit switch valve kits regulate mechanical actuation; hydraulic valve pullers simplify mud pump maintenance for 3NB-1600HL models.

• Sealing Components: Gear casing seal kits, O-rings (PS16OR, FZ897.1.3.00), and guide rings provide zero-leak sealing in high-pressure hydraulic circuits, resisting drilling fluid corrosion and thermal fatigue.

• Transmission & Structural Parts: Sprockets, pallet chain links (NE 50-04-001), bearings (NU2330, 22226C), and jaw inserts deliver smooth power transmission and heavy-load support for lifting and drilling mechanisms.

• Electrical & Auxiliary Parts: Siemens fuse boxes, Woodward synchronizing systems, and control panels ensure stable electrical operation and precise equipment synchronization in drilling rig setups.

Structure Characteristics

• Precision Tolerance Design: Critical sealing and load-bearing surfaces hold ±0.01mm dimensional accuracy, guaranteeing perfect alignment with OEM mounting points and plug-and-play installation.

• High-Wear Construction: Bearing bushes and jaw components use hardened alloy steel; sealing parts adopt oil-resistant FKM/NBR rubber; filter media features multi-layer fiberglass for maximum contaminant capture.

• Modular Assembly: Seal kits, filter assemblies, and valve kits use modular designs, cutting on-site replacement time by 40% compared to custom-fabricated parts.

• Reinforced Pressure Resistance: Hydraulic valves and sealing rings are rated for high-pressure drilling conditions, preventing blowouts and pressure loss under heavy loads.

Applicable Operating Conditions

These parts are engineered to perform in extreme industrial environments, including:

• Onshore/offshore drilling rigs (ZJ-50/315, XJ-750) with operating pressures up to 10000psig and temperatures ranging from -40℃ to 125℃

• 3NB-1600HL mud pumps and SPM TWS-600S pumping systems exposed to abrasive drilling mud and corrosive fluids

• NE bucket elevators and material handling equipment with continuous heavy-load lifting operations

• TDS hydraulic jacks and hydraulic tongs with high-frequency reciprocating motion

• Industrial electrical control cabinets and synchronization systems requiring reliable circuit protection

Maintenance & Care Recommendations

• Filter Components: Inspect oil/air filters every 200 operating hours, replace filter elements every 800 hours; flush hydraulic circuits before installing new filters to remove residual contaminants.

• Sealing Parts: Check O-rings and seal kits for cracks, hardening, or leakage during routine checks; replace every 1200 hours or immediately if damaged; lubricate sealing surfaces with compatible hydraulic grease.

• Bearing & Transmission Parts: Lubricate bearings and sprockets with heavy-duty lithium grease every 400 hours; inspect chain tension and bearing clearance monthly to avoid premature failure.

• Hydraulic Valves: Calibrate pressure relief valves quarterly; clean valve spools to remove debris that causes pressure fluctuations.

• Storage Best Practices: Store parts in a dry, dust-free environment, retain original packaging to prevent corrosion, deformation, and contamination.

On-Site Fault Repair Cases

Case 1: ZJ-50/315 Hydraulic Leakage Failure

A ZJ-50/315 rig suffered severe intermediate rod oil leakage due to worn GH 3161-04.06 sealing rings, causing hydraulic pressure loss and rig shutdown. Replacing the sealing ring and matching gaskets restored full sealing, eliminating leakage and resuming drilling operations within 2 hours.

Case 2: 3NB-1600HL Mud Pump Valve Damage

A 3NB-1600HL mud pump experienced unstable pressure due to a clogged 1R0726 oil filter and faulty relief valve. Replacing the oil filter and DB20-1-50/315 relief valve normalized system pressure, reducing pump wear and extending maintenance intervals by 3 months.

Case 3: XJ-750 Rig Bearing Failure

An XJ-750 workover rig’s tart drum assembly malfunctioned from a worn 22226C bearing, causing abnormal noise and reduced lifting capacity. Installing a new OEM-matched bearing and lubricating the assembly fixed the issue, restoring full lifting performance and preventing further damage.
