| 摘要 |
The invention relates to a pump device having a pump (8) and an energy supply device (5, 18), wherein the pump has a conveying element (9, 11) which conveys a fluid by means of supplied energy, wherein the pump has a transport state and an operating state, and wherein at least one first element (9, 9a, 10, 10′, 11) of the pump has a different shape and/or size in the transport state than in the operating state. The operating safety of such a pump device is increased by a detection device (12, 20, 21, 22, 23, 24, 25, 27, 28, 29) which detects whether at least the first element is in the operating state with respect to shape and/or size by means of a sensor. |

1. A pump device having a pump and an energy supply device wherein the pump has a conveying element, wherein the conveying element has a rotor with an impeller blade which conveys a fluid by means of supplied energy, wherein the pump has a transport state and an expanded state, and wherein at least one first element of the pump has a different shape and/or size in the transport state than in the expanded state, characterized by a detection device which detects whether the first element is in the expanded state with respect to shape and/or size,
wherein the detection device monitors the load of the energy supply device in operation and determines whether the expanded state has been reached by a comparison with a reference value or with a reference pattern. |
