Abstract

Abstract: The working principle of water circulating pumps, which had been twospeed reformed and operate in parallel mode, was theoretically analyzed. Combining with the performance test of the twospeed water circulating pumps in parallel operation, by using the minimum annual operation expenses method, the economical efficiencies of three parallel operation schemes were compared, providing a foundation for energysaving operation of water circulating pumps.

Key words: water circulating pumps, performance test, parallel, minimum annual operation expenses method
