EX Series Hydraulic Actuators EX系列液压执行器
Overview 总览
Team Corporation's EX Series Actuator is a high performance, versatile and cost-effective vibration test system component. EX Series Actuators have been developed specifically for vibration testing and integrated test systems requiring high force, long stroke or high frequency capability. The EX Series Actuator will provide continuous, consistent and reliable test results year after year.
Team Corporation的EX系列执行器是一种高性能，多功能且经济高效的振动测试系统组件。EX系列执行器专为要求高力，长行程或高频能力的振动测试和集成测试系统而开发。EX系列执行器年复一年地提供连续，一致和可靠的测试结果。
Team Corporation's EX Series Actuators are double acting, double ended, hydrostatically lubricated and designed to be stiff both mechanically and hydraulically. This is achieved by using a heavy body cross-section, a large diameter one-piece piston shaft and by keeping the trapped oil volume to a minimum. The actuator piston is internally supported by a thin film of high-pressure oil, commonly referenced as a hydrostatic bearing. This feature eliminates metal-to-metal contact, providing virtually infinite piston life. To provide position feedback, an LVDT (linear variable displacement transformer) is mounted concentrically within the piston shaft.
Team Corporation的EX系列执行器为双作用，双端，静液压润滑，并设计成在机械和液压方面都坚硬。这可以通过使用笨重的横截面，大直径的单件式活塞轴以及将截留的油量保持在*小来实现。执行器活塞由高压油薄膜内部支撑，通常称为静压轴承。此功能消除了金属之间的接触，从而提供了无限的活塞寿命。为了提供位置反馈，在活塞轴内同心安装了LVDT（线性可变位移变压器）。
