摘要： An electrical machine to facilitate transporting fluids through a pipeline is provided. The machine includes a stator (122), a rotor (120) magnetically coupled to the stator, and a housing (106) enclosing the rotor and the stator. The housing includes a wall (162) that facilitates channeling a first fluid at a first pressure through a portion (105) of the housing. The machine also includes a stator enclosure (200) defined by at least one wall that facilitates maintaining a second fluid within the stator enclosure. The stator enclosure is positioned within the electric machine housing. The stator enclosure has at least one wall that substantially isolates the second fluid from the first fluid such that only the second fluid is in flow communication with the stator. The stator enclosure has at least one wall that facilitates heat transfer from the second fluid to the first fluid. At least a portion of at least one of the stator enclosure walls is configured to facilitate equalizing the first pressure and the second pressure.

摘要： The invention relates to a centrifugal pump with a multistage design. Each stage of said centrifugal pump comprises a one-piece or multipiece housing and an impeller that is disposed therein. The pump stages are arranged between terminal pieces of inlets and outlets while being retained therebetween by means of connecting means so as to be connected to flow-guiding systems. All impellers are positioned on a pump shaft that is supported within at least two pump bearings. One end of said pump shaft is provided with a device for receiving a connecting means of a drive unit while outer support means are disposed at a mounting point in the area of the terminal pieces in order to fasten the centrifugal pump. The pump shaft (3) is supported within two pump bearings (11, 12), the maximum distance (LL) between the facing sides of said two pump bearings (11, 12) being smaller than or equal to a minimum structural stage height (LM) multiplied by the number of pump stages (2.1 - 2.5) minus 1.

摘要： A water cooled centrifugal pump is described. The pump comprises a pump body (1) with a pump chamber (4) and a water cooled motor chamber (5) communicating with each other, at least a pumping stage (7) with intake scroll (8) and impeller (9) that is housed in said pump chamber (4) and an electric motor (18) with closing casing (22) housed in said motor chamber (5) and mechanically connected with said impeller (9) through a motor shaft (10) provided with water sealing means (32). A sensor of temperature (43) is located inside a part of said casing (22) of the motor (18) in contact with the cooling water and electrically connected with a control unit (47) so as to interrupt the power supply to said motor (18) in case of detection of a temperature above a predetermined limit.
