Title: A magnetic machine or coupling
Inventor: LAING NIKOLAUS
IPC: F16C39/06
Filed: 1965-11-25
Abstract: 1,134,228. Centrifugal pumps and fans; hydraulic turbines. N. LAING. Nov. 25, 1965 [Nov. 27, 1964], No. 50210/65. Headings F1C and F1T. [Also in Divisions B2, F2, F4 and H2] Centrifugal pumps An impeller rotatable about a vertical axis, and arranged for upward and outward flow of the liquid, has secured to its upper face a hemispherical body which has permanent or induced magnetic poles and constitutes the inner member of a magnetic coupling (see Division H2). The outer member of the coupling includes a body having an internal hemispherical surface and having permanent magnet poles co-operating with the inner member; the two are separated by a partition which forms part of the wall between the pump casing and the motor casing above it. The outer member is secured to the motor rotor. A small peripheral gap is provided between the top of the (cylindrical) suction chamber and the impeller to permit limited flow from the surrounding pressure chamber. The suction and pressure chambers are also connected by openings closable by plugs to permit variation of the discharge characteristics of the pump. Permanent magnets alternating with iron plates, mutually spaced, vertically, are arranged as a magnetic separator (see Group B2) in the suction inlet. Two inlets may be provided, and a rotary valve is then disposed so as to permit liquid to be drawn from either alone, or from both, in variable proportions. The impellerinner member assembly has an upwardly - directed socketed bearing element co-operating with a downwardly-directed bearing pin, the assembly thus being maintained in position by upward magnetic attraction. The impeller has limited universal movement about the pivot, which movement serves to permit the escape of dirt particles caught between the impeller and the partition, or between the impeller and the suction chamber. The impeller shape may be adapted for this purpose. Centrifugal fans In an air-conditioning installation a fan extends upwards from the inner member of a coupling as described above. The outer member of the coupling is connected through worm gearing to one end of the rotor shaft of a motor. A second assembly of gearing, coupling and fan is secured to the other end of the shaft. In another embodiment the fan of a convector heater is secured to the outer member of a coupling as described above; the inner member is driven by turbine action (see below). Hydraulic turbines The inner member of a coupling as described above is maintained in position against a downwardly directed pivot pin by magnetic attraction and incorporates vanes. The vaned part of the member is surrounded by an inlet duct having fixed radial guide vanes, and has beneath it a fixed vertical discharge pipe communicating with the interior of the inner member. The inner member is separated from the outer member by a hemispherical partition, the outer member having secured thereto a centrifugal fan (see above).
