摘要
采用变频调速器和线性控制策略构成压力闭环控制系统,通过改变交流电动机的转速,控制空气压缩机的出口压力。试验结果证明:本系统高效节能,控制精度高,控制范围宽,安全可靠。
A closed-loop pressure control system with variable-frequency speed regulator and linear control philosophy, controls the outlet pressure of an air compressor thru changing of the rotation speed of the a. c. motor. The tests proved that this control system featured with high efficiency,energy saving, high precision and wide application as well as safety & reliability.
