转盘定位式电液伺服马达是由转盘式伺服阀和液压马达构成。它不但是一种新的电液控制元件,而且可直接用作执行器。转盘式伺服阀包括信号输入转盘和反馈转盘。由于液压油只流经液压马达,所以对转盘制造精度要求不高,也勿需设置密封装置。这种元件已应用于液压圆锥破碎机的动锥升降、液压舵机的舵角控制、掘进钻车的炮孔定位和机床移动工作台的位置控制。它是改造现有机械,实现由开关控制向伺服控制过渡的有效手段。
Turntable positioning electro-hydraulic servo motor is composed of dial servo valve and hydraulic motor. It is not only a new electro-hydraulic control element, but also directly as an actuator. Turntable servo valve includes signal input turntable and feedback turntable. Because the hydraulic oil flows only through the hydraulic motor, so the turntable manufacturing precision is not high, do not need to set the sealing device. Such components have been used in hydraulic cone crusher moving cone movements, hydraulic steering rudder angle control, driving drilling hole positioning and machine tool movement table position control. It is to transform the existing machinery, to achieve from the switch control to the servo control the effective means of transition.
