This paper theoretically and experimentally investigates the influence of the cylindrical (curved) leading edge of the worm vanes on the cavitation characteristics of the pump. Considers the disruptive flow around the worm wheel with a constant screw spacing (pitch) of an ideal liquid flow. The proposed equations, verified on pumps with worms of different types and sizes with a wide range of attack angles, can be used for the calculation of the sucking capacity of high-speed worm centrifugal pumps.
