Design Ang Research Of Double-stator Rotary Pump

Faced the deficient energy in our world, it is a crucial research subject for allcountries to explore how to get a green and renewable energy. A new kind of hydraulicpumps named double-stator rotary pumps was proposed in this paper. The advantage ofthis pump can realize multistage flow and pressure output through changing itsconnections.On the basis of a brief overview to the working principle of double-stator rotarypumps, the functional symbol is designed on the condition of the different action and thevalve flow pattern; meanwhile the appropriate rotor structure is selected by comparing andoptimizing its structure. With3d modeling software solid works established3d model ofthe motor, and then the flow field distribution was researched using the computationalfluid dynamics software. The flow field distribution was gotten, and we both analyzed theloss of different pressure between the theoretical value and the simulation value and therelationship between the exit velocity and the loss of pressure. We also got the rule of flowpulsation through analyzing the angular displacement of the rotor.This paper analyzed the leakage channels of the double-stator swing hydraulic pump,and calculated the leakage of inner and outer pumps respectively in detailed, deduced themain factors influencing the leak. Designed the experiment test platform of thedouble-stator swing hydraulic pump, did the principle experiment and basic performancetest. The experiment results verified the correctness of the working principle of thedouble-stator swing hydraulic pump, provided experiment basis for improvement designof the double-stator swing hydraulic pump.
