摘　　要：双电机双变频驱动是一种近年来发展起来的螺旋卸料离心机驱动方式,在分析该种驱动卧螺离心机结构和工作原理以及速差对产品水分和处理量影响的基础上提出了一种速差精确调节的方法,即串级控制系统调节速差,通过比较阐述了串级控制的优越性,该方法使得离心机速差控制精度大大提高,为高干度离心机的发展提供了前提保障。Bi-motor dual-frequency driver is a recently developed spiral discharge centrifuge-driven approach, this paper analysis of the kinds of driver Centrifuge structure and working principle and the speed difference of product water and treatment capacity is proposed based on the impact of precise adjustment of a speed difference of approach, that is a cascade control system regulating speed difference, by comparing the explained the advantages of cascade control, this method makes the centrifuge speed difference significantly increasing the height of the control accuracy for the senior cadres of the degree of development of centrifuge provides the prerequisite for protection.
