The Analysis For Rexroth Axial Piston Pump Common Breakdown:
1. Overheating shutdown risks are typically caused by inadequate cooling, prolonged overload, or cooling system malfunctions, resulting in excessive temperatures that trigger automatic shutdowns and interrupt operations. It is recommended to inspect the cooling apparatus, monitor temperature fluctuations, and repair any cooling issues. This hydraulic pump must remain within safe temperature limits to ensure uninterrupted, efficient performance under heavy loads.
2. Automatic adjustment failure may occur due to faults in the electronic control module, sensor inaccuracies, or damaged actuators, preventing the system from timely adjusting flow and pressure in response to load changes. It is recommended to inspect the control module, recalibrate sensors, and repair or replace actuators. This axial piston pump depends on accurate automatic adjustments to ensure optimal performance.
3. Internal blockage issues may be caused by contaminants, sediment buildup, or oil contamination, resulting in partial blockage of the oil circuit and reduced flow and pressure output. Blockages lower efficiency and increase fault risks. It is recommended to regularly clean internal passages, inspect the filtration system, and remove any obstructions. This hydraulic pump must maintain clear oil channels to ensure reliable operation and optimal performance.
