ANSON VARIABLE VOLUME VANE PUMP VP5F-B3-51:
------
1. Model Breakdown
• VP5F:
• VP: Variable Volume Vane Pump (adjusts displacement via eccentricity between stator and rotor).
• 5: Theoretical displacement of 5 cm³/rev (5 mL per revolution), suitable for medium-flow systems.
• F: Control method identifier, indicatingpressure-compensated control (Flow Compensation), which automatically adjusts displacement to maintain stable flow under varying loads.
• B3:
• B: Mounting interface type (e.g., flange or threaded connection). Class B typically denotes standard flange mounting compatible with ISO 6099 or SAE interfaces.
• 3: Design version or pressure rating code (e.g., rated pressure of 21 MPa or 3000 psi).
• 51:
• 5: May indicate series subdivision (e.g., high-pressure or economy variant).
• 1: Factory batch or customer-specific customization number.
2. Key Performance Specifications
(1) Pressure and Flow
• Rated Pressure: 21 MPa (3000 psi)
• Peak Pressure: 24 MPa (3500 psi, short-term allowable)
• Displacement Range: 0–5 cm³/rev (stepless adjustment)
• Speed Range:
• Rated Speed: 1800 rpm
• Maximum Speed: 2200 rpm (transient)
• Minimum Speed: 600 rpm (stable output)
(2) Efficiency Metrics
• Volumetric Efficiency: ≥88% (under standard conditions)
• Total Efficiency: ≥80% (optimized for energy consumption)
(3) Control Characteristics
• Pressure Compensation Range: 0–21 MPa (adjustable)
• Response Time: ≤80 ms (from pressure signal input to displacement adjustment)
• Flow Regulation Accuracy: ±2% (steady-state conditions)
3. Structural Features
• Vane-Rotor-Stator Design:
• The rotor is eccentrically mounted within the stator, with vanes pressed against the stator wall by centrifugal and hydraulic forces to form sealed chambers.
• Displacement is adjusted by varying the eccentricity between the stator and rotor (mechanically or hydraulically controlled).
• High-Pressure Adaptability:
• Stator, rotor, and vanes are made of high-strength alloy steel with quenched surfaces to resist wear.
• Axial clearance compensation (e.g., spring or hydraulic preload) minimizes internal leakage.
• Sealing System:
• Shaft seals use dual-lip fluororubber rings to prevent hydraulic oil leakage.
• Port O-rings enhance connection reliability.
• Cooling Method:
• Natural cooling (requires adequate ventilation); optional forced air or water cooling modules.
4. Typical Applications
• Machine Tool Hydraulic Systems:
• Provides precise flow control for spindle lubrication and fixture actuation in CNC machining centers.
• Injection Molding Machines:
• Regulates mold opening/closing speed and injection pressure to improve molding accuracy.
• Die-Casting Machines:
• Drives clamping units and ejection systems under high-pressure conditions.
• Light Construction Equipment:
• Powers travel motors and swing mechanisms in mini-excavators and loaders.
• Automated Production Lines:
• Supplies hydraulic power for robotic joints and material handling devices.
5. Installation and Commissioning
(1) Installation Requirements
• Orientation: Horizontal mounting with motor-pump shaft alignment error ≤0.05 mm.
• Coupling: Use flexible couplings to dampen startup shocks.
• Fluid Cleanliness: NAS 1638 Class 9 or ISO 4406 20/18, with filtration precision ≤15 μm.
(2) Commissioning Steps
1. Pressure Setting:
• Adjust system pressure via the regulator (do not exceed 21 MPa).
2. Compensation Control Calibration:
• Verify linear relationship between flow and pressure (e.g., flow reduction proportion per 1 MPa pressure increase).
3. No-Load Testing:
• Run for 10 minutes to check for leaks and abnormal vibrations; gradually load to rated pressure.
6. Maintenance and Troubleshooting
(1) Routine Maintenance
• Fluid Inspection: Test viscosity, water content, and particle contamination every 200 hours.
• Filter Replacement: Replace suction filters every 500 hours and return filters every 1000 hours.
• Seal Inspection: Check shaft seals and port O-rings annually; replace as needed.
(2) Common Faults and Solutions
【表格】
Symptom Possible Causes Solutions
Insufficient flow Worn vanes, clogged suction line Replace vanes, clean suction line
Pressure fluctuations Faulty pressure compensation valve, contaminated fluid Repair/replace valve, change hydraulic oil
Abnormal noise Bearing failure, cavitation Replace bearings, check suction vacuum
Leakage Aged seals, cracked housing Replace seals, repair/replace pump body
7. Safety Precautions
• High-Pressure Risk: Fully depressurize before maintenance; avoid live operations.
• Electrical Safety: Ground pressure compensation wiring to prevent electromagnetic interference.
• Environmental Requirements: Avoid prolonged use in humid or corrosive environments.
8. Selection Recommendations
• System Matching: Select models based on maximum flow demand (Q = Displacement × Speed) and pressure requirements.
• Control Compatibility: Ensure compatibility with existing pressure compensation signals (e.g., 0–10 V or 4–20 mA).
• Spare Parts Stocking: Recommend stocking vanes, shaft seals, and pressure compensation valves as critical spares.
