带式输送机的软启动是指输送机在重载工况下能够可控制地逐步克服整个系统的惯性而平稳地启动。对于大功率带式输送机而言,软启动不仅能够大幅度减轻传动系统本身所受到的启动冲击,延长关键零部件的使用寿命,同时还能大大缩短电动机启动电流的冲击时间,减小对电动机的热冲击负
Soft start of the belt conveyor means that the conveyor can be smoothly started under control of the inertia of the entire system in a controlled manner during heavy load conditions. For high-power belt conveyors, the soft start not only can greatly reduce the impact of the transmission system itself to start to extend the life of key components, but also can greatly shorten the motor starting current impact time and reduce the motor Thermal shock negative
