摘要
供水泵站通常采用阀门或变速(变频)调控来实现恒压供水,2种方式都涉及管路特性曲线或泵性能曲线的变化,这使得实际应用中能耗的定量计算比较繁琐.为此,借助Flowmaster流动系统仿真软件,以某恒压供水站为例,分别计算阀门调控和变速调控方式下泵系统性能的变化,并进行能耗对比分析,研究了恒压泵系统的转速和流量调节范围,为工程应用提供切实可行的计算方法.
To achieve constant-pressure water supply,water stations usually adopt valve or variable-speed (frequency conversion) controls.Such kinds of operations involve changes in the pipe characteristic curves or the pump performance curves,and make the quantitative calculation of energy consumption in practical applications more complicated.In this study,a constant-pressure water-supply station is selected as the analysis object.By means of Flowmaster software,the performance changes of the pump system under the valve control and rotational speed control are calculated respectively and the comparison analysis of energy consumption is conducted.The adjustment ranges of rotational speeds and flows for the constant-pressure pump system are also studied,which provides a practical method for engineering applications.
