Product Overview
Our HH HPU spare parts line encompasses a full range of critical hydraulic components, including plunger pumps, filter elements (suction, return, high-pressure), valves (relief, check, electromagnetic, counterbalance), pressure gauges, sensors, O-rings, bonded seals, hose assemblies, couplings, coolers, and repair kits. All parts are manufactured to OEM specifications, ensuring perfect fit, seamless integration, and consistent performance with HH-brand hydraulic power units used in drilling rigs, disc brake systems, substructure cylinders, and portable/movable HPU setups.
Key Functional Attributes
- Pressure Stability: Components withstand operating pressures ranging from 0MPa to 40MPa, preventing pressure leaks, system drops, and hydraulic failure in high-demand cycles.
- Filtration Efficiency: High-precision filter elements (FAX-63X10, HX-25X10, TFX-63X100) remove 99% of hydraulic oil contaminants, protecting pumps, valves, and cylinders from abrasion and corrosion.
- Leak-Proof Sealing: Nitrile rubber O-rings and bonded seals comply with international sealing standards, eliminating fluid loss and maintaining hydraulic system integrity.
- Explosion-Proof Compatibility: Explosion-proof electromagnetic valves and sensors meet industrial safety standards, suitable for hazardous drilling and rig environments.
- Shock & Vibration Resistance: Shock-resistant pressure gauges and heavy-duty hose assemblies endure extreme mechanical stress and field vibrations.
Structural & Design Advantages
- Precision Machining: Metal components (pumps, valves, couplings) feature tight dimensional tolerances (±0.01mm) for flawless mating with HPU housings and pipelines.
- High-Grade Materials: Wear-resistant alloy steel for pump plungers, oil-resistant nitrile rubber for seals, and corrosion-resistant brass for connectors enhance durability.
- Modular Design: Quick connectors, hose assemblies, and seal kits feature plug-and-play construction, reducing installation and replacement time by up to 40%.
- Standardized Interfaces: NPT thread, flange, and quick-connect interfaces align with global hydraulic industry standards, ensuring cross-compatibility with HPU piping systems.
Applicable Operating Conditions
These HH HPU spares are designed for heavy-duty industrial scenarios with the following operating parameters:
- Hydraulic oil temperature range: -20°C to 80°C
- System operating pressure: 0–40MPa (0–5800PSI)
- Ambient environment: Onshore drilling rigs, offshore hydraulic systems, disc brake HPU assemblies, movable/trailer HPU units, substructure cylinder systems
- Safety ratings: Explosion-proof zones, high-vibration industrial sites, and continuous-duty hydraulic operations
Proactive Maintenance & Service Recommendations
To maximize spare part lifespan and HPU uptime, follow these industry-standard maintenance protocols:
- Filter Element Replacement: Replace suction/return filter elements (TFX-400X100, FBX-400X10) every 500 operating hours or immediately if oil contamination is detected to prevent pump damage.
- Seal Inspection: Check O-rings and bonded seals quarterly for cracks, hardening, or leaks; replace preventive seals (GB/T3452.1 series) annually to avoid unplanned downtime.
- Pressure Component Calibration: Calibrate pressure gauges (YN60-III) and sensors (0–35MPa) every 6 months to ensure accurate pressure monitoring.
- Hose Assembly Check: Inspect hydraulic hoses for abrasions, bulges, or loose fittings monthly; replace damaged hose assemblies (13I-1000JM26C, 51I-1200FL40) immediately to prevent catastrophic failure.
- Valve Testing: Test relief valves and directional valves for proper function every 1000 hours to maintain system pressure regulation and flow control.

Field Failure Repair Cases (Real-World Scenarios)
Case 1: Disc Brake HPU Pressure Loss (YZ311.00 Model)
Issue: Drilling rig disc brake HPU experienced sudden pressure drops, causing brake engagement failures. Root Cause: Worn high-pressure filter element (HX-25X10) and damaged O-ring seal (14X2.65-A-S) leading to internal leaks. Solution: Replace the clogged filter element and faulty O-ring with OEM-grade HH spares; system pressure stabilized to 10MPa within 30 minutes, restoring full brake functionality.
Case 2: HPU Oil Contamination & Pump Wear (YZ094.00 Model)
Issue: Main HPU plunger pump (A10VSO10DR) made abnormal noise and failed to build pressure. Root Cause: Neglected suction filter element (IX50-250X100) allowed debris to damage pump internals. Solution: Replace the suction filter, flush hydraulic oil, and install a new plunger pump; post-repair testing showed 98% system efficiency recovery, with no further noise or pressure issues.
Case 3: Portable HPU Hydraulic Leakage (YZ403 Model)
Issue: Movable HPU developed severe oil leaks at the coupling assembly, causing fluid loss and reduced output. Root Cause: Worn combined sealing gasket and damaged coupling component. Solution: Install a new coupling assembly (PK200/3/17-00) and replacement bonded seal; leakage was fully resolved, and the HPU resumed continuous portable operation for drilling support tasks.
Frequently Asked Questions (FAQ)
| Question | Answer |
| Are these spares direct replacements for original HH HPU components? | Yes, all parts match OEM part numbers, dimensions, and performance specs for YZ094/YZ095/YZ096/YZ232/YZ296/YZ311/YZ403/YZ5000 series HPUs, ensuring perfect fit and function without modifications. |
| How do I select the correct filter element for my HPU model? | Cross-reference your HPU model (e.g., YZ094.00) and filter type (suction/return/high-pressure) with the listed part numbers (FAX-63X10, TFX-400X100, HX-H250X20) to confirm compatibility; verify micron rating and dimensions for exact matching. |
| What is the service life of these HH HPU spare parts? | Under normal operating conditions, seals/O-rings last 12–18 months, filter elements 500–1000 hours, pumps/valves 3–5 years, and hose assemblies 2–3 years; lifespan varies with maintenance frequency and operating environment. |
