Abstract

1434226 Axial flow pumps S A ROBERTS 23 Oct 1974 [2 Nov 1973 5 June 1974] 50969/73 and 25049/74 Heading F1C [Also in Division H2] An axial-flow pump unit having an annular liquid flow passage 19 formed between an outer tubular housing 1 and an inner two-part plastics casing 7, 8 incorporates an electric induction motor 2 designed to run on multi-phase A.C. supplies of 25 volts or less and of frequency greater than 50 Hertz, e.g. 75-400 Hertz. The motor has a cage rotor 3 mounted in two carbon bearings 11, 12, and the casing is coaxially located in the housing 1 by sets of guide vanes 20 (21), Fig. 2 (not shown) which eliminate liquid swirl in flow passage 19. Current is delivered to the field coils 6 via leads 22 in an insulating member 23. The hydrofoil shaped blades 17 of the axial-flow impeller 15 of the pump have an angle of 9‹5' at the tip and 10‹38' at the root. In the embodiment of Fig. 3 (not shown), the electric motor and pump impeller are mounted within a sleeve (29) which is supported by resilient material (30) within a main housing member (28), the arrangement thereby reducing the transmission of vibrations to a central heating system in which the pump unit is operating. Plastics material for the housing, casing or impeller may be glass reinforced polyphenylene oxide. A supply circuit (Division H2) is described with reference to Fig. 4 (not shown).
