80年代前期,液压技术陆续出现一些新发展。下面从元件、液压油、测试系统(应用)和其他等方面谈谈。一、元件(包括辅件) 液压元件和辅件的额定压力和流量基本上未见向高、大方向发展,但也曾出现个别大型液压缸,也出现几种小型泵和缸。在结构方面,比较突出的是集成化、插装化,数字化。在控制方面,则电脑化、比例化和节能化。 1、液压泵高度集成化结构表现在小型泵站(组)上,这种泵组包括电动机(直流较多,交流也有)、泵、控制阀和油箱等,它可作为机床夹紧装置和自卸车的油源。可以把它安装在任何方便的位置,对用户十分方便。近年还出现
In the early 1980s, there were some new developments in hydraulic technology. The following from the components, hydraulic oil, test systems (applications) and other aspects of conversation. First, the components (including accessories) Hydraulic components and accessories rated pressure and flow basically to see the high, the general direction of development, but there have been a few large hydraulic cylinder, there are several small pumps and cylinders. In the structure, the more prominent is integrated, plug-in, digital. In control, the computerization, scaling and energy-saving. 1, the highly integrated structure of the hydraulic pump performance in the small pump station (group), this pump group includes the motor (more DC, AC also), pumps, control valves and fuel tanks, which can be used as a machine tool clamping device and self Unloading truck oil source. It can be installed in any convenient location, very user-friendly. In recent years also appeared
