摘要:
分析冷水循环泵的工作现状,利用变频器将传统循环供水系统改造成变频调速式系统,实现平滑的软启动和软停车,以减少对电网的冲击.设计一台变频器控制两台水泵的方案,由冷水循环泵、变频器,以及扩展控制回路共同构成一个闭环控制系统.结果表明,变频改造后,闭环控制系统能够较好地对水泵进行控制和监测,实时反馈压力的变化并做出准确、迅速的判断和动作,保证系统的恒压供水.
Abstract:
After the analysis of the current working status of the cold water circulating pump,the technological transformation of the traditional water supply control system is implemented into a variable-frequency speed regulating system using a converter to realize smooth soft-start and soft-stop and reduce the impact on the electric network.A closed-loop control system composed of the cold water circulating pump,the converter and the extended circuit,is designed so that a converter could control 2 pumps.The experimental results show that the pump can be better controlled and monitored for real-time pressure feedback,and accurate and rapid response so that a constant pressure for the water supply system could be ensured.
