摘要:
Die Erfindung betrifft eine Rotoranordnung (1) zum rotierbaren Einbau in ein Pumpengehäuse einer elektrischen Pumpe für flüssige Medien, insbesondere Kühlmittelpumpe, mit einem Antriebsteil (3) und einem mit dem Antriebsteil (3) drehfest verbundenen Pumpenteil (2), wobei der Pumpenteil (2) einen axial an einem oberen Ende der Rotoranordnung (1) angeordneten Strömungsbereich (29) mit einer Zuströmöffnung (20) und mehreren Flügeln (23) zur Leitung von Kühlmittel aufweist und wobei der Antriebsteil (3) zum Antrieb nach elektromotorischem Prinzip eine magnetische Substanz aufweist und mindestens zweipolig magnetisiert ist. Vorteile in der Fertigung sind dadurch erreichbar, dass der Antriebsteil (3) aus separat voneinander gespritzten miteinander verbundenen Teilen mehrteilig ausgebildet ist.
摘要:
The invention relates to a pump device, comprising i) an impeller; ii) a pump housing surrounding an inner region, at least partially, having an inlet and an outlet, wherein the impeller is provided in the inner region of the pump housing. In at least one plane (Q) vertically to the longitudinal extension of the pump housing, the wall of the pump housing has at least one first sub-region and at least two additional sub-regions. The at least one first sub-region contains at least 60 weight percent, based on the total mass of the at least one first sub-region, of at least one non-magnetic material, wherein the additional sub-regions contain at least 41 weight percent, based on the total mass of the additional sub-regions, of at least one ferromagnetic material. In the plane (Q), each addition sub-region is adjacent to at least one first sub-region, wherein the at least one first sub-region and the additional sub-regions are connected to one another in a material-fit manner. The invention further relates to a housing comprising the features as described for the pump housing. The invention further relates to a method for producing a pump housing, the method comprising the steps: a) Providing a first material; b) providing a further material; c) forming a pump house precursor, wherein at least one first sub-region of the pump housing is formed of the first material, and wherein at least two additional sub-regions of the pump housing are formed of the further material; and d) treating the pump housing precursor at a temperature of at least 300 ⁰C.

摘要:
Transient thermal stresses in a gas turbine engine rotor (20) are reduced by generating eddy currents in an electrically conductive portion of the rotor (20). In one embodiment, magnets (42) are mounted on a ferrite support (44) inside a shaft (30) movable relative to the rotor (20). A sleeve (50) of copper or other very good electrical conductor may be mounted inside the central bore (32) of the rotor (20) to improve the generation of eddy currents.
