slip regulator

A slip frequence regulation methord is used,and its main circuit is the AC-DC-AC voltage source frequency conversion circuit.

介绍了一种由AT89C51单片机为主控制器的交流变频调速系统,它采用转差频率调节方式,主回路采用交-直-交电压型变频电路,并用M/T法实现电机转速的测量。

Based on the analysis of its principle through samples, an introduction is given to the mechanical method of replacing the original device deviation regulator by the empty device deviation regulator.

在流量计为主要计量器具的原油动态交接计量过程中,进口流量计因配套原因很难使重复性和允差都达到合格,本文实例分析了其原理,介绍了以空器差调节器替换原装器差调节器的机械方法,以及用流量计系数进行补偿实现零差量交接方法的流量计系数的确定和差量的计算模型。
