摘　　要：针对国内建筑用卧螺离心机的不足,通过采用泵控式速度电液伺服控制系统,设计一种新型的全液压驱动与控制系统,能够根据建筑泥水的密度、黏度、固相含量和粒度的变化,实时采集离心机的转速信号,并将其转换成电信号,控制液压泵的排量,从而控制液压马达的转速实现泥水分离。采用此控制系统,离心机完全适应泥水参数的变化。A new type of fully hydraulic drive and control system was designed by using pump-control speed electro-hydraulic ser- vo control system to overcome the shortage of domestic decanter. According to the different mud-water parameters including the densi- ty, viscosity, solid-phase content and particle size, centrifugal speed signals were collected real-time and were translated into electri- cal signals to control the flow of hydraulic pump and to further control the velocity of hydraulic motor to realize the separation of mud- water. It can make the centrifuge always in the best condition.
