The Analysis For Rexroth A2FM Fixed Displacemen Piston Motor Common Breakdown:
1. Under certain operating conditions, the hydraulic motor experiences brief surges in pressure, likely due to transient valve sticking, air entrainment in the oil line, or rapid load changes. A detailed inspection of the control valves, oil seals, and venting system is recommended, with necessary adjustments to valve response times and air removal, to maintain pressure fluctuations within acceptable limits reliably and efficiently.
2. The piston motor has been observed emitting abnormal noise accompanied by slight vibrations, which may result from loose internal components, improper mounting, or worn transmission parts. It is advisable to perform a comprehensive inspection of the overall structure, tighten mounting bolts, and reinforce the transmission system to eliminate noise and vibration risks, thereby ensuring long-term stable operation and optimal performance consistently.
3. Occasional loss of control signals and data transmission errors in the axial piston motor are likely caused by electromagnetic interference, loose wiring, or control module faults. It is recommended to inspect shielding and grounding, verify all cable connections, and assess the control module’s condition, while considering a software upgrade to ensure accurate signal transmission and restore efficient, stable communication throughout the system reliably.
