浅谈一次泵变流量压差控制“关键点”位置的选取

Selection of“Key Point”Position for Primary Pump Variable Flow Water System with Differential Pressure Control

压差控制法作为目前一次泵变流量水系统可靠、主要的控制方法得到了大量应用,但在实际使用过程中,关键点的位置选取相对简单和模糊,给实际的运行带来不利。本文通过理论分析结合实际设计工程,就关键点位置的合理选取进行阐述,得出了现阶段相对合理、可行的结论。

Differential pressure control method as the primary pump variable flow water system is reliable,the main control method had been used a lot of,but in the actual use process,the location of the point selection is relatively simple and vague,bring adverse to the actual operation.In this paper,through theoretical analysis combined with the actual engineering design,an exposition on reasonable selection key position was made,and a feasible conclusion was obtained relatively reasonable at this stage.
