CBDL-F5/F5/F5 Triple Gear Oil Pump
A specialized hydraulic power unit designed for construction machinery, theCBDL-F5/F5/F5integrates three independent gear pumps to enable synchronized hydraulic oil delivery across multiple circuits. Below is a detailed breakdown of its technical features, applications, and selection guidelines:
------
I. Technical Characteristics
1. Modular Triple-Pump Design
• Comprises three standalone gear pump units (F5/F5/F5) mounted on a shared shaft in series or parallel configuration. Each unit supports independent flow/pressure control, ideal for coordinating multiple actuators (e.g., excavator boom, arm, and slewing).
• Constructed from high-strength aluminum alloy or cast iron, it withstands operating pressures up to25 MPa(nominal). Axial floating compensation technology minimizes internal leakage, achieving volumetric efficiency ≥90%.
2. Wide Temperature Adaptability
• Operates in hydraulic oil temperatures ranging from-20°C to 90°C, thanks to fluororubber seals and high-temperature bearings.
• Compatible with viscosities from9 cSt to 2,000 cSt, supporting mineral oils, synthetic fluids, and biodegradable hydraulic media.
3. Low Noise & Long Service Life
• DU self-lubricating bearings and radial balancing reduce gear meshing vibration, lowering noise by5–8 dBcompared to conventional pumps.
• Hardened gears and shafts (surface treatment) extend wear resistance by30%, with a design life exceeding8,000 hours.
------
II. Typical Applications
1. Construction Machinery
• Excavators: Synchronize boom lifting, arm extension, and slewing for enhanced efficiency.
• Cranes: Coordinate luffing, telescoping, and slewing motions during lifting operations.
• Wheel Loaders: Optimize bucket tilting and boom cycles for faster material handling.
2. Industrial Equipment
• Hydraulic Test Benches: Deliver parallel pressure loading to multiple test points via independent circuits.
• Injection Molding Machines: Drive mold opening/closing, ejection, and injection with precision.
3. Agricultural Machinery
• Combine Harvesters: Control header lifting, reel rotation, and threshing mechanisms in rugged terrain.
------
III. Selection & Usage Guidelines
1. Flow/Pressure Matching
• Select single-pump displacement (e.g.,5 mL/rev for F5 units) and calculate total flow as:
Qtotal=Displacement (mL/rev)×Speed (rpm)×3 (pumps)Q_{\text{total}} = \text{Displacement (mL/rev)} \times \text{Speed (rpm)} \times 3 \ (\text{pumps})Qtotal=Displacement (mL/rev)×Speed (rpm)×3 (pumps)(Typical speed range:1,000–3,000 rpm).
• Ensure system pressure ≤25 MPa(nominal), with a20% safety margin.
2. Installation & Maintenance
• Mount via flange connection (e.g.,B-type square flange) for simplified integration.
• Monitor oil cleanliness (NAS 9 grade or better) to prevent gear wear.
• Replace hydraulic oil after500 hoursof initial operation, then every2,000 hoursor as needed.
3. Troubleshooting
• Low Flow: Check for clogged suction filters or excessive gear end clearance.
• Abnormal Noise: Verify oil viscosity or inspect for bearing failure.
• Leakage: Replace aged seals or inspect for casting defects (e.g., porosity).
