    摘要:

    传统的压力控制回路中,动力元件都采用传统的单作用泵。当回路只用一个泵提供压力时,压力控制回路无法满足系统对多个流量的需求。而多泵和多速马达是基于双定子理论所设计的一种液压元件,可实现一个泵(马达)的多输出。当代替传统单作用泵和单作用马达用于传统液压回路中时,此时的液压回路就是一种新型的液压回路。由于元件的特殊性,使系统可满足多输出、多功率的需求。新型液压回路减少了很多控制元件,所以在实现与传统液压回路相同功能时,新型液压回路可节约很大的能量。多泵多马达调压系统的实验结果表明,由于泄漏原因,导致泵随压力增加,实测流量减少;双定子泵的容积效率随着压力的增大而减小,机械效率和总效率随之增大而增大。尽管由于一些不可控因素导致的误差,但也证明了回路的可行性和元件的原理正确性。

    Abstract:

    In traditional pressure control loops, the power elements use a conventional singleacting pump. When the circuit uses only one pump to provide pressure, the pressure control loop cannot meet the system’s need for multiple flows. The new multipump and multispeed motors were based on the double stator theory and a new type of hydraulic components was developed, which can achieve a pump (motor) multioutput. When the conventional singleacting pump and singleacting motor were used in the conventional hydraulic circuit, the hydraulic circuit at this time was a new type of hydraulic circuit. Due to the special nature of the components, the system can meet the needs of multiple outputs and multiple powers. Since the new hydraulic circuit reduced a lot of control elements, the new hydraulic circuit can save a lot of energy when implementing the same functions as the traditional hydraulic circuit. The experimental results of the new multipump and multispeed motor pressure control circuit showed that with the increase of the system pressure, the measured flow of the double stator pump was decreased; the volumetric efficiency of the double stator pump was decreased with the increase of pressure difference, the mechanical efficiency and total efficiency were increased with it. Although the error was caused by some uncontrollable factors, it verified the feasibility of the circuit and the rationality of hydraulic components. The experimental results laid the foundation for the innovation and development of multipumps (motors) for other hydraulic circuits.
