摘　　要：针对传统的卧螺离心机控制系统存在稳定性差、工作效率低的问题,设计了一种卧螺离心机变频调速PLC控制系统;详细介绍了该系统中共直流母线变频调速系统、副电机随动方案及负载率调整方法、PLC控制系统、组态界面的设计。实际应用表明,该系统运行稳定,提高了离心机的性能。In view of of decanter centrifuge problems of bad stability and low working efficiency of traditional control system a frequency-conversion speed-regulation and PLC control system of decanter centrifuge was designed. Design of frequency-conversion speed-regulation system of common DC bus, servo scheme and adjusting method of load rate of vice motor, PLC control system and configuration interface of the system were introduced in details. The actual application shows that the system runs stably and improves performance of centrifuge.
