一、导言由浙江大学流体传动与控制研究室和天津市液压气动工程技术研究所共同研制开发的电液比例恒压变量轴向柱塞泵能根据控制电信号控制变速系统为一恒定的压力。作为新型恒压油源,它具有电液控制、多功能衍生、结构简单等基本技术优势,可广泛应用于有一定动态性能要求的中高压、中、大流量的各类容积控制系统。其技术性能与国际上同类产品相当。
I. INTRODUCTION The electro-hydraulic proportional axial piston pump developed by the Fluid Power Transmission and Control Research Laboratory of Zhejiang University and the Tianjin Institute of Hydraulic Pneumatics Engineering can control the transmission system to a constant pressure according to the control electric signal. As a new type of constant pressure oil source, it has the basic technical advantages of electro-hydraulic control, multi-function derivation and simple structure. It can be widely applied to various volume control systems of medium, high, medium and large flow with certain dynamic performance requirements. Its technical performance and international similar products.
