Китай A11VO190 Rexroth A11VO145 Гидравлический насос экскаватора | PartDIC®_Excavator гидравлика, Дизельный двигатель, SKS Гидравлический

The A11VO190 and A11VO145 are axial piston pumps, это означает, что они используют вращающийся блок цилиндров с поршнями, расположенными по кругу для создания гидравлического давления..

This design offers excellent efficiency and high power density, making them suitable for demanding applications like excavators.

Starting with the A11VO190, it is a robust pump with a displacement of 190 куб.см за оборот. The displacement refers to the volume of fluid the pump can deliver in one revolution. A higher displacement indicates a higher flow rate and more powerful performance. The A11VO190 is capable of delivering high-pressure hydraulic fluid up to 450 бар, allowing it to handle heavy-duty excavator operations.

The A11VO145, с другой стороны, has a slightly smaller displacement of 145 куб.см за оборот. While it provides a slightly lower flow rate compared to the A11VO190, it still offers considerable power and efficiency. The maximum pressure rating for the A11VO145 is also 450 бар, ensuring reliable operation under demanding conditions.

Both pumps feature variable displacement control, which means the flow rate can be adjusted to match the specific requirements of the excavator.

This feature enables precise control over various functions, such as the movement of the boom, рука, и ведро. It also helps optimize energy consumption, reducing fuel consumption and operating costs.

Для обеспечения прочности и долговечности, the A11VO190 and A11VO145 are constructed using high-quality materials and undergo rigorous testing. They are designed to withstand harsh environments and demanding work cycles commonly encountered in excavator applications. The pumps have robust bearings, поршни, and seals that can handle high pressures and provide reliable performance over an extended period.

Both pumps are also equipped with integrated pressure relief valves, which protect the hydraulic system from overpressure situations. This feature enhances the safety and reliability of the excavator by preventing damage to the pump and other hydraulic components.

Кроме того, the A11VO190 and A11VO145 are designed for easy installation and maintenance. Они имеют компактную и легкую конструкцию, making them suitable for various excavator models and configurations. The pumps are also compatible with different types of hydraulic fluids, ensuring versatility and compatibility with existing systems.
