| 发明名称 | Centrifugal pump assembly | ||
| 摘要 | The invention relates to a centrifugal pump assembly with at least one impeller, with a suction union, which is situated on the entry side of the impeller, and with a pressure union, which is situated on the exit side of the impeller. A flow sensor and at least one guidance element are arranged in a conduit section, which is formed by the suction union and/or by the pressure union. The guidance element is suitable for influencing the flow prevailing in the conduit section. | ||

| 主权项 | 1. A centrifugal pump assembly with at least one impeller, a suction union (4) on an entry side of the at least one impeller, a pressure union (12) on an exit side of the at least one impeller, and a vortex flow sensor and at least one guidance element (22, 24) in a conduit section formed by the suction union (4) or the pressure union (12), wherein said at least one guidance element is a rib (22) projecting radially inwardly from an inner wall (26) of the conduit section and at least one profile plate (24) which projects inwardly from the inner wall (26) of the conduit section and extends transversely to the rib (22), and which is orientated transversely to a flow direction (S) of a fluid to be delivered by the pump, and wherein said at least one guidance element influences a flow in the conduit section such that disturbing turbulences which compromise measurements of the vortex flow sensor are kept away from the sensor. | ||
