Abstract: Based on a system engineering method, macro design scheme of lifting pump is proposed. From the structure and function of lifting pump system, the paper analyzes the function of each part of lifting pump and mutual restriction and influence be-tween each other in the system. And establishes a mathematical model at work of the key functional part axial flow pump and turbine motor. The mathematical models of the axial pump and the turbine motor were then coupled together by flow differences to model the system according to the operating requirements of the lifting pump. According to the three functions of the system, the constraint conditions and the corresponding design variables for the design of axial flow pump and turbine motor are put forward. And the objective function of the optimization design is pointed out according to the working characteristics of axial flow pump and turbine motor. Finally, according to the system search and optimization design, the optimization design process is established. By using the system engineering method, a more complete design scheme for the macroscopic lifting pump system has been established, which provides some guidance for the efficient and fast design of lifting pumps.
