摘要： A pump includes a housing having an inlet and an outlet configured to convey fluid, an impeller configured to convey the fluid from the inlet to the outlet, the impeller being arranged on a rotatable shaft, and a balance drum configured to relieve axial thrust. The balance drum includes a rotor rotationally fixedly connected to the shaft, the rotor having a high and low pressure sides, a stator stationary with respect to the housing, a relief passage extending between the rotor and the stator from the high pressure side up to the low pressure side of the rotor, a return passage connecting the low pressure side of the rotor to the inlet. An intermediate passage opens into the relief passage between the high pressure side and the low pressure side of the rotor. A blocking member is configured to influence the flow through the intermediate passage.

摘要： A method of evaluating a wear state of an assembly of a flow machine, in particular, of a bearing arrangement of a pump or turbine. For determining a wear characteristic, a mechanical query signal having a pre-definable signal shape is generated by a signal generator and a response signal generated from the query signal is detected using a sensor in contact with the assembly. The response signal is varied in dependence on a variation of a physical operating value of the assembly in accordance with a characteristic pattern, the wear characteristic is determined from the variation of the response signal and the wear state is evaluated using the wear characteristic.

摘要： A method for operating a pump, for conveying a fluid from a low-pressure side to a high-pressure side of the pump includes determining a current rate of change of pump vibrations and comparing the current rate of change with a limit for the rate of change or determining a current vibration of the pump and comparing the current vibration with a vibration amplitude limit for the vibration, storing the limit for the rate of change or the vibration amplitude limit in a surge controller, providing a control signal when the current rate of change reaches the limit or when the current vibration reaches the vibration amplitude limit, and changing a control variable of the pump by the control signal, such that the vibration is reduced and an unstable operating state of the pump is avoided.
