Using four parallel pump , this paper analysis and compare the energy consumption of various schemes , its conclusion is instructional in optimizing this regulation 本文以四臺(tái)并聯(lián)水泵為例,對(duì)各種運(yùn)行方案的能耗進(jìn)行了比較分析,所得結(jié)論對(duì)于這種調(diào)節(jié)方式的方案優(yōu)化有一定的指導(dǎo)意義。
Flow regulated by changing the number of parallel pumps , during the regulating , working condition of individual pump or fan will change a lot , there will be two problems , one is efficiency of the pump or fan will decrease , anther is there will be overloading 多泵并聯(lián)改變運(yùn)行臺(tái)數(shù)的調(diào)節(jié),在調(diào)節(jié)過程中,單機(jī)工況會(huì)發(fā)生很大的改變,這可能導(dǎo)致兩個(gè)問題,一是效率的降低,二是超載現(xiàn)象的發(fā)生。
