摘要
多泵并联变频供水是二次供水系统中最主要的运行方式,但在实际应用中仍会因为工况分析不全面、泵组搭配不当等问题导致节能效果不佳.为此,引入可靠性分区并提出变频恒压并联泵组加、减泵控制逻辑对变频恒压并联泵组进行运行优化,使泵组运行时的能效水平和可靠性均得到提升.最后通过算例验证并联泵组可靠性优化措施的节能效果,将优化后的全变频控制方案与传统全变频控制方案进行对比.结果表明,优化后的方案比传统方案更加节能,可为二次供水并联泵组节能运行提供参考.
Abstract
Multiple pumps in parallel frequency conversion water supply is the most important operation mode in sec-ondary water supply system.But in practical application,it leads to the poor energy saving effect because the working condition analysis is not been comprehensive and the pump group is mismatched.Therefore,this paper introduces the re-liability partition and proposes the control logic of adding and subtracting pumps for frequency-constant pressure parallel pumping units,and optimizes the operation of frequency-constant pressure parallel pumping units based on this logic,so that the energy efficiency and reliability of pumping units can be improved when they are running.Finally,an example is used to verify the energy-saving effect of parallel pumping unit reliability optimization measures,and the optimized fully variable frequency control scheme and the traditional fully variable frequency control scheme is compared.The results show that the optimized scheme is more energy efficient than the traditional scheme,which can be used as a reference for the energy-saving operation of secondary water supply parallel pumping unit.
