电液伺服阀是一种控制精度高,动态响应快的电—液转换元件。它建立了控制器和液压动力部件之间的联系构成了电液伺服系统。目前,普通中小流量的电液伺服阀频宽多在100c/s以下,大流量的伺服阀频宽还要低些。这样的指标已能满足工业和国防上大部份系统的使用要求。然而,对某些特殊的使用场合,如高频振动台,飞行模拟转台以及高速轧钢设备等,
Electrohydraulic servo valve is a control of high precision, fast dynamic response of the electro-hydraulic conversion element. It establishes the connection between the controller and the hydraulic power components that make up the electro-hydraulic servo system. At present, ordinary small and medium-sized electro-hydraulic servo valve bandwidth more than 100c / s in the following, large flow servo valve bandwidth is lower. Such indicators have met most of the system’s industrial and defense requirements for use. However, for some special occasions, such as high-frequency vibration table, flight simulation turntable and high-speed rolling equipment, etc.,
