| 摘 要： | 直驱式力马达阀（FMV）因响应快、控制精度高、抗污染能力强等特点被广泛应用于轧机自动厚度控制系统。对FMV的各项性能指标进行有效、实时的检测是控制钢材生产成本的一个重要环节。传统的伺服阀测试系统一般通过负载腔之间的流量、压力变化来检测其静态特性，这一原理可有效用于三位四通伺服阀的静态性能检测。而直驱式力马达阀是一种特殊的三通阀，它的性能指标无法像常见的三位四通伺服阀一样通过负载腔之间的流量、压力变化来检测。提出并实现了一种直驱式力马达阀性能测试方法，根据液压阀测试性能指标，设计、搭建了用于检测直驱式力马达阀性能的测试平台，有效检测了FMV的性能指标并绘制了其性能曲线。结果表明，根据伺服阀测试标准所提出的直驱式力马达阀性能测试方法以及所搭建的测试系统可有效用于FMV的静态性能指标的检测。

| Abstract: | Force motor valve (FMV) is widely used in the hydraulic automatic gauge control (AGC) system of rolling mill due to characteristics of fast response, high control accuracy and strong anti pollution ability. It is an important part to control the steel production cost by detection of the performance index of the FMV effectively and in real time. The traditional servo valve test system detects the static characteristics through the load and pressure changes between the traffic cavities, which can solve the performance test of three position four way servo valve. However, FMV is a special three way valve and it is hard to test its static characteristic curve like three position four way servo valve. So we propose a FMV testing method. The test platform is designed and built according to the hydraulic valve testing performance index for detecting the performance of a force motor valve. By it the performance characteristics of force motor valve can be tested effectively, and the performance curves can be drawn. The results show that the F method can effectively detect the static performance index of FMV. |
