大型泵站自动控制系统设计

Design of Automatic Control System for Large Pumping Station

通过对泵站的电路控制系统进行改进,利用水位、压力开关实现泵站的自动开停和水位报警,同时包含电机降压启动、过流保护等功能,避免因泵站司机脱岗或操作不当造成的水泵和电机烧毁事故。

By way of improving circuit control system of the pumping station and making use of water level,pressure switch to realize automatic starting & stopping and alarm for water level,including functions such as voltage-reducing starting and over-current protection,accidents of pump and motor burning due to off-duty or mis-operation of pumping station operator are avoided.
