摘要

多输出叶片泵是基于“双定子”原理而提出的一种新型叶片泵，传统定量泵是1个定子对应1个转子，且仅输出一种定流量。而该新型泵是1个转子对应2个定子，且1个泵体又分为内泵和外泵，当改变其输出方式时，可以实现单个定量泵体输出多级定流量的功能。针对该泵在流量切换的过程中的压力冲击问题，提出增设阻尼孔、适当增加管路内径的方法来减缓压力冲击。基于AMESim软件进行模块化建模，仿真可知适当增加管路内径可以减少压力冲击，但并不能完全消除。最后，搭建该多输出泵单执行机构系统进行实验，检验多输出叶片泵切换工作方式时压力冲击的抑制效果。结果验证了设计的有效性，对日后双定子多输出叶片泵多执行机构的分析与应用奠定了一定的基础。

Abstract

The multi-output vane pump is a new vane pump based on the “double stator” principle. A conventional metering pump is one stator corresponding to one rotor and outputs only a constant flow. The new pump is a rotor corresponding to two stators, and one pump body is divided into an inner pump and an outer pump. When the output mode is changed, the function of outputting multi-stage constant flow of a single quantitative pump body can be realized. This paper analyzes the pressure shock of the pump during the flow switching process. It is proposed to add a damping hole and appropriately increase the inner diameter of the pipe to slow down. Modular modeling based on AMESim software shows that the increase in the inner diameter of the pipe can reduce the pressure shock, but it cannot be completely eliminated. Finally, the multi-output pump single actuator system was built to test the pressure shock suppression effect of the multi-output vane pump switching mode. The results verified the effectiveness of the design. It lays a foundation for the analysis and application of multi-actuator with double stator multi-output vane pump in the future.
