Energy Loss and Efficiency of Baoying Pumping Station System

Abstract

In order to decrease energy loss and improve efficiency for Baoying pumping station system, under different operating conditions, energy loss of each part was calculated, and the influences of the number of running pumps and the pump assembly head on the energy consumption and efficiency were analyzed. The results show that under design condition, with the increment of the number of running pumps, the energy loss rate of main pump units is increased first and then decreased, and that of the auxiliary equipment, power transmission and transformation is gradually decreased and increased respectively. Under the same head, the system efficiency is the highest when two pump units are running. As the pump assembly head increasing, the system efficiency is increased gradually, and it is decreased when the head reaches 8 m. The results are of great significance for the optimal design and optimization operation of similar pumping station systems.
