Abstract

This paper proposes a unique counter-rotating type of the pumping system which is composed of the two-stage impellers and the peculiar motor with the double rotors, and discusses remarkable advantages of the system. The front and the rear impellers are driven by the inner and the outer rotors, respectively, keeping the relative-rotational speed constant and keeping the counter-rotational torques same. Such operating conditions make not only the unstable performance in the low discharge but also the cavitation in the high discharge suppress smartly, in the optimum cooperation with the impellers and the rotors. The model test proved that there is not the rising portion of the head characteristics and the front impeller speed decreases with increase of the discharge as if the impeller takes the place of the inducer.
