摘要
液压机作为一种重要的压力加工设备被广泛应用于国防与民用领域。本文分析了传统液压机的基本构成与存在问题,在此基础上,介绍了一种综合液压与开关磁阻伺服驱动技术两者优点的新型直接驱动容积控制液压机。论述了直驱泵控液压机的工作原理与特点,指出该液压机具有节能性好、体积小、噪声低、结构简单、对油液过滤精度要求低,且易于实现计算机控制等优点,是目前新型液压机最重要发展方向之一。
Hydraulic machine ,which is as kind of very important press machining equipment, has been widely used in national defence and civilian industry.The basic constitution and existing problem of the traditional hydraulic machine have been analyzed in this text.A new kind of direct driving volume control hydraulic machine ,which synthesizes the advantages of both hydraulic and switched reluctance servo driving technology, has been introduced. The operating principle and characteristics of direct-driving pump control hydraulic machine have been discussed. It is pointed out that this kind of hydraulic machine has the merits of energy saving,smaller bulk,lower noise,simpler construction,lower precision level of oil filtering, and easily realizing computer control, which is one of the important development orientations at present.
