摘要
针对供水系统存在水压不稳的问题，采用了固定转速泵和变频调速泵配合使用的控制方法，提出了以8751单片机作为控制器的供水系统方案，解决了恒压供水的问题。
?The occurrence of water pressure instability in water feed system is overcome by the combined use of changeless speed pump and VF speed-adjusting pump and the introduction of the water feed system based on 8751 microprocessors, as described in this paper, so as to accomplish constant pressure water feed.
