    摘要： An improved vacuum pump mechanism is described in which an intersecting solid or perforated element is arranged to intersect a channel member. Relative movement of the intersecting solid or perforated element and channel member causes gas molecules to be urged from inlet to an outlet of the pump. Gas molecules are constrained within the channel member and interaction of the gas molecules with the flat and smooth surfaces of the intersecting solid or perforated member influence momentum of the gas molecules so that they are directed towards the outlet. In one embodiment, the channel member is formed as a helix and the intersecting solid or perforated elements are disk-shaped. An alternative embodiment is provided having the channel member configured as a spiral and the perforated elements as cylindrical skirts. The pump provides significant improvements in pump capacity, reduced power consumption and size of pump.

    摘要： A multi-stage, double volute, centrifugal pump has an intermediate discharge and a final discharge constructed so that the pulses in the fluid at the discharge stages created by the impeller vanes passing the lips of the volute are eliminated within the pump assembly by the use of an impeller having an odd number of vanes and the volute lips are located 180* apart, and separate flow paths of equal length lead from each lip to a zone of confluence. The point of convergence for the intermediate discharge is in the pump case, the point of convergence for the final discharge is also in the pump case.

    摘要： A centrifugal pump (1, 110) includes an apparatus for the removal of particles, wherein the centrifugal pump includes an impeller (6, 106). A fluid (2, 102) can be conveyed by means of the impeller (6, 106) through a suction passage (5, 105) from a suction stub (3, 103) to a pressure stub (4, 104). The impeller (6, 106) is rotatable in a stator (7, 107). A gap (9, 19, 109) is arranged between the stator (7, 107) and the impeller (6, 106), wherein the gap (9, 19, 109) opens into a storage space (11, 21, 111) for particles. The storage space (11, 21, 111) communicates with the suction passage (5, 105) via a return line (12, 112) running through the stator (7, 107).
