Abstract

1,028,452. Making radial flow impellers. PULSOMETER PUMPS Ltd. March 9, 1965 [March 9, 1964], No. 9893/64. Heading B3A. A rotor disc 12 of a radial flow pump or turbine is formed with integral vanes 15 which may be straight or curved. A cast or forged disc 16 is formed with grooves 18 (Fig. 3, not shown) and the disc is machined so that the bottoms of the grooves are constituted by thin webs 19 (Fig. 5, not shown). The machine surface of the disc 16 is placed on the disc 12 so that the grooves are aligned with the blades and the parts are welded together with weld seams 20 filling the grooves. The rotor is finally machined to the line Z-Z.
