Innovation design of submersible motor pump based on Triz

It is hard to remove or install large scale submersible motor pump when it is on the process of serial-parallel conversion under different circumstances. In order to enhance its efficiency, Triz principle was applied to design innovative submersible motor pump in this research. First, Multiscreen-method was adopted to analyse submersible motor pump systematically. Then a conflict matrix was obtained by existing technology contradiction to select feasible principle for optimal submersible motor pump design. Finally, this paper gives an optimal design of submersible motor pump. Working efficiency can be enhanced by solving operating condition jump in the pit of submersible motor pump. The application of submersible pump can be extended and the technology of submersible pump in our country can be upgraded. This principle is helpful to achieve a multifunctional and reduce material reserve.
