AXIAL FLOW PUMP HAVING A NON-CIRCULAR OUTLET CROSS-SECTION |
| 摘要 |
The invention relates to a hydraulic pump (10) comprising a pump shaft (52) and a casing (46) delimiting a liquid circulation duct (44) in which the cross-section of the outlet orifice (12) is flattened and is oriented such that the liquid outlet direction (14) is inclined from a longitudinal axis (22) of the pump shaft passing through the casing, the casing comprising a first segment (100a) in which the inside surface (102a) has a circular cross-section centred on said longitudinal axis (22) and surrounding a pump impeller (60) supported on the pump shaft (52). According to the invention, the first segment (100a) has a downstream end starting from which the cross-section of the casing inside surface becomes flattened. |

1. Hydraulic pump (10) comprising a pump shaft (52) and a casing (46) delimiting a liquid circulation duct (44) in which the cross-section of the outlet orifice (12) is flattened and that is oriented such that the liquid outlet direction (14) is inclined from a longitudinal axis (22) of the pump shaft passing through said casing, the casing comprising a first segment (100a) in which the inside surface (102a) has a circular cross-section centred on said longitudinal axis (22) and surrounding a pump impeller (60) supported on the pump shaft (52),
characterised in that said first segment (100a) has a downstream end from which the cross-section of the casing inside surface becomes flattened. |
