水泵并联运行工况点的确定在泵站设计中占有极其重要的地位，关系着水泵选型的合理性和泵站运行的经济性，采用折引特性曲线法对某扬黄灌溉泵站不同型号水泵在相同水位下并联运行的工况进行分析，验证水泵选型和电机功率选择。

Determination of the operating point of pumps in parallel plays a vital important role in design of pumping station, which is related to the rationality of the pump selection and the economic operation of the pump station. By using the method of folding characteristic curve yellow irrigation pumping station of parallel operation under different types of pumps at the same level condition analysis, verify pump selection and motor power selection.
