1980年5月18日至20日,西德液压和气动研究与应用促进协会在阿亨举行了第四届流体技术学术座谈。这次座谈共发表了45篇论文,其中,有关液压行业方面的文章有33篇,归纳为四类:第一类是液压技术中有关节能措施,讨论了液压驱动的节能和能量回收,液压装置中的节能、定量泵节流及控制系统节能的新方案。第二类文章是关于在液压系统中应用电子技术进行控制和调节。探讨电子控制技术在液压系统中的现状和未来。近几年来,由于比例阀(以比例电磁铁或力矩马达作为电一机转换元件)得到急剧的发展,使电液伺服驱动赢得重要地位。电液比例阀就是电子技术和液压技术之间的一种“接口”。此外还认为在液压技术中会不断地增加微处理机的应用。随着计算机(或微理机)
On May 18-20, 1980, the West Association for Hydraulics and Pneumatics Research and Applications facilitated the 4th Fluid Technology Academic Symposium in Achensee. A total of 45 papers were published at this symposium. Among them, 33 articles on the hydraulic industry were grouped into four categories. The first category concerned energy-saving measures in hydraulics, and discussed energy-saving and energy recovery of hydraulically driven hydraulics In the energy-saving pump metering and control system energy-saving new program. The second category is about the application of electronic technology in hydraulic systems for control and regulation. Discuss the current situation and future of electronic control technology in hydraulic system. In recent years, due to the rapid development of proportional valve (proportional electromagnet or torque motor as a power conversion element), electro-hydraulic servo drive has won an important position. Electro-hydraulic proportional valve is a kind of “interface” between electronic technology and hydraulic technology. In addition it is also believed that the hydraulic technology will continue to increase the application of microprocessors. With the computer (or micro-machine)
