一种小型嵌入式恒压变量泵的研制

Development of a Small Embedded Constant Pressure Variable Pump

根据液压舵机小型化需要,研制了一种新型嵌入式恒压变量柱塞泵;设计出了实物样机并进行了试验研究。结果表明,该泵具有极好的定压精度和动态稳定性,易于实现高压;尤其在功率质量比、结构小型化以及旋转密封性方面具有外挂泵无法比拟的优势。

According to the miniaturization of hydraulic steering gear, a new type of embedded constant pressure variable displacement piston pump was developed. The physical prototype was designed and tested. The results show that the pump has excellent constant pressure accuracy and dynamic stability, and it is easy to achieve high pressure;especially in terms of power quality ratio, structural miniaturization and rotary sealing, it has the advantage that the external pump can’t match.
