近年来在生产设备中越来越多地采用液压传动。同时,不论在技术方面,还是在经济方面,对液压传动设备参数的要求愈来愈高。因此,在液压元件及液压回路的组成方面,不仅力求改善目前传统液压元件的品种,而且还要探讨新型的元件和系统,以满足不断增长的技术和经济上的要求。液压逻辑元件及集成回路就是其中的一种。 本文引述了各种类型的液压逻辑元件、它们的联接及在液压回路上的应用;详细叙述了组成液压集成回路时应用带有逻辑元件的通用组合块的可能性及其结构;最后指出了采用带逻辑元件的液压回路与采用带滑阀式换向阀的传统系统相比,在技术上和经济
In recent years, more and more hydraulic transmission has been used in production equipment. At the same time, the requirements for hydraulics equipment parameters are increasing both technically and economically. Therefore, in terms of the composition of hydraulic components and hydraulic circuits, it not only seeks to improve the current varieties of conventional hydraulic components but also explores new types of components and systems to meet the growing technical and economic requirements. Hydraulic logic components and integrated circuits is one of them. In this paper, various types of hydraulic logic elements are introduced, their connection and their applications in hydraulic circuits. The possibility and structure of applying common combination blocks with logic elements in forming hydraulic integrated circuits are described in detail. Finally, Compared with the traditional system with spool valve, the hydraulic circuit with logic element is technically and economically
