Abstract

1350417 Rotary positive-displacement machines LACY-HULBERT & CO Ltd 16 Nov 1972 [20 Dec 1971] 58992/71 Heading F1F In a sliding-vane pump the or each vane, or "blade", D is non-radial and to obviate jamming due to reduction of the blade length by wear the slot depth is rendered great enough to place the centre of gravity X of a fully worn and retracted blade D 1 on the trailing side of a radial line R from the axis of the rotor A, the line being perpendicular with the slot. Since the blade D 1 would be held in the position shown by centrifugal force warning of serious blade wear is given by an obvious reduction of pumping efficiency.
