气动薄膜调节阀关键点的调校

The calibration of key set points for pneumatic membrane control valve

介绍了气动薄膜调节阀调校中熏如何通过输入信号与行程之间的线性对应关系熏将气开式调节阀的始点和气关式调节阀的终点误差判断,由原来固定输入信号后考核行程确定误差大小,转换为固定行程后改变输入信号判断误差大小,使调校中误差处理更容易。

During the calibration of pneumatic membrane control valve, based on the linear corresponding relation between input signal and journey, the error examine method for both the gas open control valve start point and gas close control valve end point can be changed from the original examine journey to determine error size after fixing input signal to determine error size after fixing the journey then change input signal. The input signals error settlement can be realized easily in this way.
