Research of pump-selection in pressure-superposed water supply

摘要

In design and implementation of pressure-superposed water supply, pump-selection for programs often involves many parameters. Parameter calculation and program identification, comparison are quite complex, some factors are difficult to quantify. According to pump operating point distribution and curve conditions of superposed water supply pipe network systems, summarizes the technical parameters of pumps during the course of high efficiency range. Use one-dimensional fluid simulation software FLOWMASTER for analysis and simulation model. When the pump selection for programs and operation scheduling are reasonable, it is superposed that water supply systems can be obtained expected good results.
