摘　　要：为了探究夹马口取水泵站系统的节能运行方式,推导出水泵机组能源单耗随水泵效率及管路效率变化的数学模型。通过模拟水泵在并联管和单管输水下的运行工况,分析水泵效率、管路效率、能源单耗随管路输水方式变化的趋势。结合夹马口取水泵站的工程特点,优化设计研究中提出水泵出水总管并联输水的运行方式。数值模拟计算结果表明,并联管输水时管路效率及泵站效率明显提高,机组能源单耗明显减低,可以实现夹马口泵站的节能运行。In order to explore the energy-saving operation mode of Jiamakou Pumping Station system,according to the mathematical formula,a mathematical model of energy consumption was derived at the change of the efficiency of the pump and pipe. We analyzed the trend of thepump efficiency,pipe efficiency and energy consumption changing with the water pipeline by simulating the pump operating conditions underparallel water pipe and tube water pipe. Combining with the engineering characteristics of Jiamakou Pumping Station,an operational mode ofthe pump water outlet pipe parallel deliver water was presented in the optimal design study. By numerical simulation calculating,the resultsshow that the pump efficiency and pipe efficiency increase significantly,energy consumption decrease significantly under the operational modeof parallel water pipe,which can realize the energy-saving operation of Jiamakou Pumping Station and provide technical support of theenergy-saving operation and optimal design for pumping station with multi pipeline.
