电液伺服系统兼有电气与液压两方面的优点,它的响应和动态品质好,已日益为人们所认识,不仅军工方面早已广泛应用,近年来在民用工业上的应用也日渐增多,特别是那些大功率与自动化动态指标要求比较高的系统(如大型振动台、船舶舵机、防摇装置、轧钢设备、模拟器和工业机器人等)应用尤多。组成大功率电液伺服系统的关键元件之一,须采用大流量规格的电液伺服阀,通常人们多
The electro-hydraulic servo system has the advantages of both electrical and hydraulic. Its response and dynamic quality are increasingly recognized by the people. Not only the military has long been widely used, but also the applications in the civilian industry have been increasing in recent years. In particular, Systems with high requirements for high-power and automated dynamics, such as large shakers, ship steering gear, anti-roll devices, rolling equipment, simulators and industrial robots, are particularly popular. The composition of high-power electro-hydraulic servo system, one of the key components to be used in large flow size electro-hydraulic servo valve, usually more people
