Applications:
Competitive Advantage:
1. Spherical oil distribution in axial piston motor achieves 360° self-aligning sealing with leakage <0.1%, extending oil replacement intervals.
2. High-strength alloy steel plunger rods withstand 35MPa pressure, reducing wear by 40% in metallurgical rolling mills.
3. Smart diagnostic interfaces piston motor enable remote monitoring of oil temperature/pressure, cutting downtime by 30%.
4. Energy-regenerative axial piston motor recover braking energy via closed circuits, reducing total consumption by 15%-20%.
5. Full-speed range (0-3000 rpm) supports military vehicles in low-speed climbing and high-speed maneuvers with <5% torque fluctuation.
The Analysis For Rexroth A6VM Piston Motor Common Breakdown:
1. Sticking of displacement mechanism: Displacement switching delay >0.5 seconds
Repair: Ultrasonic cleaning of control piston and flushing with VG46 anti-wear hydraulic oil
2. Bearing pitting: Periodic abnormal noise in specific speed ranges
Repair: Replace FAG/INA bearings with cryogenic pretreatment (-196℃ liquid nitrogen)
3. Unstable control pressure: Actuator speed fluctuation >±5%
Repair: Check pilot relief valve spring stiffness and test accumulator precharge pressure
4. Excessive case pressure: Case drain temperature >80℃
Repair: Check return line backpressure (<0.3MPa) and clean case drain passages
5. Internal leakage in servo piston: Swashplate position drift
Repair: Replace servo piston seals and check clearance (≤15μm)
