The Analysis For Rexroth A2FM Fixed Displacemen Piston Motor Common
Breakdown:
1. Misalignment during installation or operation can lead to
increased wear on A2FM motor components and abnormal vibration,
affecting fluid circulation and pressure transmission. Realigning
the equipment and verifying all connections is critical, along with
checking the hydraulic motor’s installation angle to ensure proper
alignment and optimal performance.
2. Excessive wear of internal pistons may result from contaminated
hydraulic oil, prolonged high-load operation, or insufficient
lubrication, reducing energy transmission efficiency and
compromising sealing. A thorough inspection and replacement of worn
components are necessary. Evaluating the condition of the piston
motor assembly is also vital to ensure normal system operation.
3. Damaged or worn hydraulic lines can cause pressure drops and
fluid leakage in the A2FM motor system, negatively affecting
overall stability. Such issues are often due to environmental
factors and prolonged use. Regular inspection and timely
replacement of affected lines, along with evaluation of the
hydraulic motor connections, are necessary for reliable operation.
