摘要
液压伺服电液执行器将控制模块和液压动力模块集成一体,模块发出指令到控制伺服阀,控制液压动力模块以直线位移(或角位移)输出力(或力矩),驱动被控对象并通过位移反馈、压力反馈完成调节过程,实现各种功能闭环控制。内置物联网通讯模块可远程进行阀、液压缸运行状态监测及故障诊断。采用高性能微处理控制器,可实现与多种现场总线传感器进行通讯,如SSI、 5V差压正交TTL编码器、Profuse-DP总线等多种数字传感器接口,同时可实现与多种现场总线控制。可实现位置控制、实时位置速度控制、压力(力)控制、位置-压力(力)复合控制、速度-压力(力)复合控制、多轴同步控制和协调控制、多轴控制器组合作为从轴和主控制器通讯,多达64轴同步控制或32轴的协调控制。
The hydraulic servo electro-hydraulic actuator integrates the control module and the hydraulic power module,the control module issues instructions to the intelligent controllable servo valve,the control hydraulic power module outputs force(or torque)with linear displacement(or angular displacement),drives the controlled object and completes the adjustment process through displacement feedback and pressure feedback to achieve closed-loop control of various functions.The built-in Internet of Things communication module can remotely monitor the operating status and fault diagnosis of the valve and cylinder.Using high-performance microprocessing controller,it can communicate with a variety of fieldbus sensors,such as SSI,5V differential pressure orthogonal TTL encoder,Profuse-DP bus and other digital sensor interfaces,and can realize a variety of fieldbus control.It can realize position control,real-time position speed control,pressure(force)control,position-pressure(force)compound control,speed-pressure(force)compound control,multi-axis synchronous control and coordinated control,multi-axis controller combination as the slave axis and the main controller communication,up to 64 axis synchronous control or 32 axis coordinated control.
