The parameters of impellers and the pump housing as key assembly to differential velocity vane pump of eccentric-noncircular gears has been designed in this paper. By researching vane spacing angles, vane numbers, vane angle and maximal opening angle on impellers, the results are gained that vane spacing angles are the periodic function of noncircular gear angular velocity, vane numbers is identical with centrodes vane numbers of noncircular gear. Assuring right and reliable working to the impellers, numbers, positions and opening angles of the matching holes of the pump housing are analyzed; defining that actual impeller vane angle must be less-than theoretical value, numbers of the matching holes must be vane numbers and opening angles of the matching holes must be less-than theoretical value, which provide the condition for concrete structure design for differential velocity vane pump of eccentric-noncircular gears.
