Abstract

216,939. Cooper, T. L. R. March 6, 1923. Pumping - machines.-A combined electric motor and centrifugal pump of the type described in Specification 126,099 is cooled by allowing a portion of the water pumped to flow back over the rotor, an external cooling-jacket being dispensed with. To allow of such flow, gaps 21 - - 24 are left between the pump impeller 20 and volute 22 and the rotorsleeve 15 and inlet chamber 13 respectively. The gap 24 can be adjusted by a screwed sleeve 26 and the gap 21 by moving the rotor lengthways. To allow of this adjustment washers 27 are inserted in the thrust bearing 28. The stator-coils 10 are enclosed in a thin-walled chamber 3 containing an insulating liquid as described in Specifications 113,627 and 117,296, [both in Class 35, Dynamo-electric generators &c.], and communicating by vents 37, 38 with an expansion chamber 36. An air and water-tight connection box is arranged in the outer wall of the chamber 3. Drain holes and air vents controlled by screw plugs and cocks are provided. The faces of the gaps 21, 26 may be provided with renewable parts. In a modification the downward extension of the wall of thepump volute forming one side of the gap 21 is replaced by a removable plate.
