本文介绍了一个用于上钢十厂带钢塔式酸洗生产中的模拟式射流位置调节系统。在阐明其工作原理的同时还着重介绍了系统中的远距离射流位置模拟传感器、比例放大器及气-液伺服阀。最后,以钢带位置到液压缸活塞位置间的传递函数和一些静、动态测试结果说明了系统的调节特性及其主要性能指标。 This article describes an analogue jet position control system for strip pickling in the ten-unit strip steel plant. In clarifying its working principle, it also introduces the remote jet position simulation sensor, proportional amplifier and gas-liquid servo valve in the system. Finally, the transfer function between the strip position and the piston position of the hydraulic cylinder and some static and dynamic test results show the adjustment characteristics of the system and its main performance indicators.
