Key Design Features
1. Double-Acting Piston Structure
• Achieves continuous oil suction and discharge through bidirectional piston movement, ensuring superior flow stability compared to single-acting pumps.
• Precision-fitted piston and cylinder reduce leakage, with volumetric efficiency exceeding95%.
2. High-Pressure Capability
• Rated pressure:35 MPa (5,075 psi); peak pressure up to40 MPa (5,800 psi).
• Ideal for high-pressure hydraulic systems, such as hydraulic breakers and injection molding machines.
3. Wear-Resistant Materials & Surface Treatment
• Piston, cylinder, and valve plates are made ofhigh-strength alloy steel, hardened to HRC58-62 via quenching and nitriding for excellent wear resistance.
• Seals usefluororubber (FKM) or polytetrafluoroethylene (PTFE), compatible with temperatures from-30°C to +120°Cand corrosive environments.
4. Low Noise & Vibration
• Optimized flow channel design minimizes hydraulic shock, while precision bearings reduce mechanical vibration (operating noise ≤75 dB(A)).
5. Modular Design
• Pump body, drive shaft, and control valves are independently replaceable, lowering maintenance costs by30%.

Selection & Configuration Recommendations
1. Pressure Matching
• Ensure system operating pressure does not exceed the pump’s rated pressure (35 MPa), with a10% safety margin.
2. Speed & Flow Rate
• Select speed range based on load: low-speed (500–1,000 rpm) for heavy-duty applications; high-speed (1,500–2,000 rpm) for light-duty tasks.
3. Fluid Compatibility
• Standard hydraulic oils: Use standard seals.
• Fire-resistant fluids (HFA/HFB): Require special seal materials.
4. Cooling Method
• For continuous operation, equip with air or water cooling to prevent oil overheating (recommended ≤80°C).
------
Maintenance & Troubleshooting
1. Daily Inspections
• Oil level: Maintain at 1/2–2/3 of the tank capacity.
• Temperature: Monitor for abnormal rises (indicating internal leakage or cooling issues).
2. Periodic Replacements
• Hydraulic oil: Replace every 2,000 hours or annually (adjust based on environment).
• Filters: Replace every 500 hours to prevent contaminant ingress.
3. Common Faults
• Insufficient flow: Check suction lines for blockages or internal pump leakage.
• Pressure fluctuations: Adjust relief valves or inspect safety valves for sticking.
• Abnormal noise: Tighten couplings or replace worn bearings.
