Applications:
Competitive Advantage:
1. Dual pressure-rated axial piston motor (400/450 bar) handles sudden load shocks in mining and oil drilling.
2. Spherical oil distribution technology minimizes piston motor leakage (<0.1%) and extends hydraulic oil service life.
3. Gearless transmission design reduces axial piston motor maintenance frequency and saves 30% lifecycle costs for axial piston motor.
4. Low-inertia piston rotor group achieves start-stop response times <200 ms in port handling equipment.
5. Precise flow control (±1.5%) maintains tension stability in paper/metallurgy production for higher product quality.
The Analysis For Rexroth A6VM Piston Motor Common Breakdown:
1. Abnormal wear of piston: Flow fluctuation with increased noise and reduced efficiency
Repair: Replace matched piston-cylinder components and check lubrication system
2. Scoring on valve plate: Increased pressure pulsation and abnormal housing temperature
Repair: Precision grinding or replacement of valve plate with surface roughness Ra≤0.2μm
3. Swashplate adjustment failure: Displacement unresponsive to control signals
Repair: Clean servo piston chamber and check proportional valve coil impedance (normal 2-5Ω)
4. Shaft seal leakage: Oil leakage at drive shaft
Repair: Replace dual-lip seals and check shaft journal wear (tolerance ±0.01mm)
5. Low charge pressure: Cavitation noise in closed circuit
Repair: Check charge pump gear clearance (standard 0.03-0.05mm) and replace inlet filter
