针对多机驱动的长距离带式输送机存在启动冲击大、正常运行时耗能不合理、各驱动电机出力不均的问题,通过对带式输送机的软启动、节能运行和功率平衡三方面的理论分析,提出了合理的启动速度、加速度曲线,实现节能运行的带速与运量关系及调节驱动电机功率平衡的措施,同时对带式输送机常用调速及功率平衡的驱动装置进行了对比,为设计选择提供全面参考。
The long-distance belt conveyor with multi-machine driving has the problems of big start-up impact, unreasonable energy consumption in normal operation and unequal output of each driving motor. Through three aspects of soft start of belt conveyor, energy saving operation and power balance The paper puts forward the reasonable starting speed and acceleration curve, the relationship between the belt speed and volume of energy-saving operation and the measures to regulate the power balance of the driving motor. At the same time, the commonly used speed regulation and power balance drive device of belt conveyor Contrast, provide a comprehensive reference for the design choice.
