Applications:
4. For quay crane slewing platforms, 350bar continuous pressure with planetary reducers enables 0.5r/min precise control under 200-ton loads. Independent drain ports limit backpressure to 0.3bar, extending maintenance intervals to 10,000 hours.
Competitive Advantage:
1. The A2FM motor delivers rapid response under variable load conditions, adapting quickly to changes in demand, and when paired with a piston motor, it provides precise adjustments and swift performance recovery, ensuring that dynamic industrial processes remain uninterrupted and highly efficient during fluctuating operational challenges, guaranteeing continuous optimal performance always.
2. The A2FM motor is engineered to reduce energy consumption significantly through optimized design and efficient hydraulic operation, and when used with a hydraulic motor, it minimizes power losses and improves overall system performance, resulting in lower operating costs and a more sustainable solution for industrial applications, delivering exceptional energy savings.
3. The piston motor equipped with planetary gear reducers enable 800kW power output for deep mine conveyors. Dual-motor synchronization error ＜0.5% with 20,000-hour bearing life under 350bar continuous pressure.
The Analysis For Rexroth A2FM Fixed Displacemen Piston Motor Common Breakdown:
1. Miscalibration of the control unit in the A2FM motor can result in deviations in pressure, flow, and displacement parameters, leading to unstable system operation. Such errors may be due to sensor aging or software issues. Regular recalibration and firmware updates, along with inspection of the hydraulic motor control system, are essential for accurate performance.
2. Rapid degradation of piston rings in the A2FM motor may occur due to inadequate lubrication, overloading, or contaminated hydraulic oil, resulting in seal failure and increased internal leakage that reduce energy transmission efficiency. Regular inspection and timely replacement of worn piston rings, along with evaluation of the piston motor, are essential to maintain system integrity.
