The A11VLO190 pump is part of the A11VO series by Rexroth, known for its axial piston variable pump design.
With a displacement of 190 cc/rev, this pump is suitable for medium to large-sized concrete applications. It operates on the swashplate principle, providing variable flow rates and pressure levels to meet the dynamic demands of concrete machinery.
The pump is designed to handle a maximum pressure of up to X bar, making it suitable for high-pressure hydraulic systems commonly found in concrete pumps and mixers. Its compact design ensures easy integration into different hydraulic setups, contributing to the overall efficiency of the concrete equipment.
Maintenance:
Proper maintenance is crucial to ensure the longevity and optimal performance of the A11VLO190 pump. Regular checks on oil levels, filtration systems, and the condition of seals and gaskets are essential. Routine inspections help identify potential issues before they escalate, reducing downtime and minimizing repair costs.
Regular oil changes using the recommended hydraulic oil are essential to maintain the pump's efficiency and protect its internal components from wear. It's important to adhere to the manufacturer's guidelines regarding oil type, viscosity, and change intervals.
Repair:
In the event of a malfunction or component failure, a systematic approach to repair is necessary. The A11VLO190 pump is designed with replaceable parts, simplifying the repair process. Common repair tasks include replacing worn-out piston assemblies, seals, bearings, and other high-wear components.
Access to a comprehensive repair manual provided by Rexroth is invaluable during the repair process.
It guides technicians through disassembly, inspection, and reassembly steps, ensuring that each component is properly installed and calibrated.
Key Parts:
Piston Assemblies: The axial piston design relies on piston assemblies to generate hydraulic pressure. These assemblies are subjected to wear and tear over time and may require replacement during routine maintenance.
Seals and Gaskets: Seals and gaskets are critical for preventing hydraulic fluid leaks. Regular inspection and replacement of these components are essential to maintain the pump's integrity and prevent contamination.
Bearings: Bearings support rotating components within the pump. Timely replacement of worn bearings is crucial to prevent damage to other internal parts and ensure smooth operation.
Swashplate Mechanism: The swashplate is a key component that controls the axial piston's movement. Proper calibration and maintenance of the swashplate are essential for achieving accurate and variable flow rates.
