Abstract:
Yaoguannan pumping station is one of the key projects in the Xingouhe extension and widening project, and its main task is to pump water from the Wujing Port area to the Bejing-Hangzhou Grand Canal and to storm drainage as well. The design pump head of the pumping station is extra-low, which is only 0.7 m.. Based on the test results of model pump system from the constructed pump station projects and the comparisons from the perspectives of hydraulic performance, engineering investment, construction, and operation management, the tubular pump model that has been successfully adopted in the Liyangxincun pumping station was selected for the Yaoguannan pumping station. Due to that the maximum pump head is about 3 times of the design head, the investment and operation costs for the Yaoguannan pumping station were analyzed between two design schemes of fixed and adjustable motor speeds. The investment for the pump set was much larger but the effect in lowering operation cost was not obvious for the scheme of adjustable motor speed, thus the fixed speed scheme was selected finally.
