- Abstract:
- A county in northeastern Sichuan Province has implemented a water supply project along the Jialing River to address issues such as insufficient water supply guarantee rate and low water quality qualification rate. Specifically, the water intake component of this project utilizes a floating boat water intake pumping station. While the water intake method offers advantages such as good water quality and reduced investment costs, operational challenges were identified during the flood season. During this period, the river water contains a significant amount of scum and exhibits high turbidity, which can lead to blockages in the suction pipes of the pumps and failures in the pump shaft cooling water systems. Additionally, shutdowns of the variable frequency pump may occur during the frequency adjustment process due to the high static head. Through a detailed analysis of the defects in the planar layout of the grid, the scum screen was optimized, and a novel type of scum trap was designed. The operating conditions of the variable frequency pump were thoroughly evaluated, leading to the proposal of a new water balance regulation mode. Furthermore, recommendations were provided regarding the selection of cooling water sources. After renovation, the water intake pumping station operates stably and can provide reference for similar projects.
