与单节流口和双节流口阀控液压随动系统相比,四节流口阀控液压随动系统的精度高、稳定性好,适用于负载大、精度要求高的设备。本文介绍这种系统在仿形铣床、强力旋压机床、风洞设备及长钢轨连续闪光对焊机等有着不同要求的设备上的应用,各项参数的选择计算,主要结构设计及系统试验示例。
Compared with the single-throttle and double-throttle valve controlled hydraulic servo system, the four-throttle valve controlled hydraulic servo system has high accuracy and good stability, and is suitable for equipment with large load and high precision requirements. This paper introduces the application of such system on equipment with different requirements such as profiling milling machine, powerful spinning machine, wind tunnel equipment and long rail continuous flash butt welding machine, selection and calculation of various parameters, main structural design and system test examples .
