The Analysis For Rexroth A2FM Fixed Displacemen Piston Motor Common Breakdown:
1. Blockages in the hydraulic passages can impede the flow of hydraulic oil in the A2FM motor, causing a drop in pressure and unstable power transmission. Deposits or internal corrosion may be responsible. Regular cleaning of the channels, use of high-efficiency filters, and inspection of the piston motor flow paths are recommended to restore optimal operation.
2. Although the A2FM motor is primarily hydraulically driven, erratic electrical signals in its integrated control system can affect flow regulation and pressure control, causing delayed responses. It is essential to inspect the circuitry and control modules, and evaluate the hydraulic motor’s electronic interfaces to ensure accurate feedback and restore proper operation.
3. Oxidized Oil Clogs Damping Orifices: Thermal degradation produces ＞50μm sludge blocking Φ0.8mm orifices. Maintain oil temperature ＜65℃ and replace ISO VG 46 oil every 2000h.
