The Analysis For Rexroth A2FE Fixed Displacemen Piston Motor Common
Breakdown:
1. During prolonged operation, the A2FE motor may suffer internal
leakage due to contaminated hydraulic oil, aging seals, or improper
installation, resulting in unstable pressure, reduced power output,
and increased temperature. The fault often causes abnormal
vibration and noise, requiring inspection of the hydraulic motor,
cleaning, and seal replacement to restore stability.
2. Under heavy load or prolonged use, the A2FE motor may experience
overheating that accelerates internal wear and oil degradation,
resulting in performance loss and system failure. It is critical to
inspect the cooling system, improve ventilation, and maintain an
axial piston motor with proper hydraulic oil to control operating
temperatures.
3. If abnormal vibration is observed in the A2FE motor, it may
be caused by loose components, improper installation, or internal
wear. Continuous vibration reduces system stability and increases
noise. A thorough inspection of all fasteners and the piston motor
assembly is recommended to tighten connections and restore proper
balance.
