3 week ago
Product details
1. Model Breakdown
• PSVD2-17E:
• PSVD: KYB variable-displacement axial piston pump series, indicating aswashplate-type axial piston variable pumpthat adjusts displacement via swashplate angle.
• 2: Design version or series identifier (may correspond to pressure rating or control type).
• 17: Theoretical displacement of17 cm³/rev(17 mL per revolution).
• E: Control type identifier, typically denotingelectromagnetic control(e.g., pressure compensation or flow control).
• Solenoid Valve: Integrated electromagnetic valve for remote control of pump displacement, pressure, or direction (e.g., proportional solenoid for precise adjustment).

3. Structural Features
(1) Core Components
• Swashplate-Type Piston Design:
• Axially arranged pistons adjust displacement via swashplate angle, suitable for high-pressure systems.
• Precision-machined cylinder block and port plate minimize leakage.
• Solenoid Control Valve:
• Integrated proportional or on/off solenoid for displacement/pressure regulation.
• Example: Pressure compensator maintains system pressure stability; flow control matches load demands.
(2) Sealing and Durability
• Shaft Seal: Dual-lip fluororubber seals prevent hydraulic oil leakage.
• Bearings: High-load roller bearings support axial and radial forces.
• Materials: Pistons and cylinder blocks use quenched alloy steel (surface hardness ≥HRC58).
(3) Cooling and Lubrication
• Natural Cooling: Relies on casing heat dissipation (ensure ventilation space).
• Forced Cooling Option: Customizable water or air cooling modules.
4. Typical Applications
(1) Construction Machinery
• Excavators: Drives travel motors, swing mechanisms, and hydraulic cylinders.
• Wheel Loaders: Controls work device (boom, bucket) lifting and tilting.
• Cranes: Provides hydraulic power for luffing, slewing, and telescoping.
(2) Agricultural Machinery
• Combine Harvesters: Powers header lifting and conveyor systems.
• Tractors: Controls rear suspension and PTO (Power Take-Off).
(3) Industrial Equipment
• Die-Casting Machines: Regulates clamping force and injection speed.
• Injection Molding Machines: Controls screw rotation and mold opening/closing.
5. Solenoid Valve Functions
(1) Pressure Compensation Control
• Principle: Solenoid adjusts swashplate angle based on system pressure to maintain outlet pressure stability.
• Application: Multi-actuator parallel systems (e.g., excavators operating boom and bucket simultaneously).
(2) Flow Control
• Principle: Solenoid input current (e.g., 0–10V or 4–20mA) regulates pump displacement for flow-load matching.
• Application: Precision speed control (e.g., injection molding machine screw rotation).
(3) Directional Control
• Principle: Solenoid switches oil paths for pump forward/reverse rotation or unloading.
• Application: Bidirectional drive systems (e.g., crane winch mechanisms).
6. Selection and Installation Guidelines
(1) Selection Criteria
• Displacement Matching: Calculate based on system maximum flow demand (Q = Displacement × Speed).
• Pressure Matching: Ensure rated pressure ≥ system maximum working pressure.
• Control Compatibility: Verify solenoid signal type (e.g., PWM, analog) matches controller requirements.
(2) Installation Requirements
• Orientation: Horizontal installation with pump shaft and motor shaft coaxiality error ≤0.05mm.
• Fluid Cleanliness: NAS 1638 Class 8 or ISO 4406 18/16; install suction filters.
• Wiring: Solenoid power supply must match rated voltage (e.g., 12V/24V DC) with overload protection.
7. Maintenance and Troubleshooting
(1) Routine Maintenance
• Fluid Inspection: Test viscosity, water content, and particle contamination every 500 hours.
• Seal Replacement: Replace shaft seals and O-rings every 2,000 hours.
• Solenoid Calibration: Annual checks on response time and linearity.
(2) Common Faults
【表格】
Symptom Possible Cause Solution
Insufficient Displacement Solenoid jamming, swashplate wear Clean solenoid, replace swashplate assembly
Pressure Fluctuation Faulty pressure compensator, contaminated fluid Repair/replace compensator, change hydraulic oil
Abnormal Noise Bearing damage, cavitation Replace bearings, check suction lines
Solenoid Unresponsive Power failure, coil burnout Check circuitry, replace solenoid coil
