摘要 |
A pump intake device comprises a main body which includes a side wall section having an inner side and an outer side, an intake section extending from the outer side of the side wall section and an intake passage extending through the intake section, the intake passage having an inner surface and an entry end and an exit end with a central axis extending between the entry and exit ends, where a first portion of the inner surface has one or more first guides thereon for directing fluid passing through the intake passage so that, in use, the fluid leaves the exit end at the first portion with an exit angle which is inclined relative to the central axis. |

1. A pump intake device comprising a main body which includes a side wall section having an inner side and an outer side, an intake section extending from the outer side of the side wall section and an intake passage extending through the intake section, the intake passage having an inner surface and an entry end and an exit end with a central axis extending between the entry and exit ends, a first portion of the inner surface which includes one or more first guides thereon for directing fluid passing through the intake passage so that in use said fluid leaves the exit end at the first portion with a first exit angle which is inclined relative to the central axis, and a second portion of the inner surface of the intake passage which includes one or more second guides thereon for directing fluid passing through the intake passage so that in use said fluid leaves the exit end at the second portion with a second exit angle which is inclined relative to the central axis, the second exit angle being less than the first exit angle. |
