| 摘 要： | 针对当前多数恒压供水系统水泵运行状态单一、不能自动完成多台水泵循环工作,影响水泵使用寿命且使其它水泵长期停歇造成资源浪费的问题。提出了采用支持图形化逻辑电路编程的LOGO!可编程控制器,依据增泵条件和减泵条件,实现了变频恒压供水系统多泵自动循环工作和定时自动切换的控制功能。实际运行结果表明,该方法控制有效,系统运行稳定可靠、功能完善。

| Abstract: | In view of the current most water-pump of the constant pressure water supply system running state single、and can not complete multiple pumps cycling work automatically,Thus to affect water-pumps used life and cause the problem which the resources are wasted,because of other water-pumps can not work for long time.This paper put forward to adopt LOGO! programmable controller which supports to use the graphical logical circuit to program,and according to the condition for increasing water-pumps and the condition for reducing water-pumps,the control functions of multi-pumps cycling automatically and switching pumps automatically in an assigned time are implemented.The Practical running result indicates that this method can effectively control the system,the system running has the stable reliability and perfect function. |
