Abstract
2802. Hartmann, P. F. Feb. 4. Centrifugal pumps.-End-thrust balancing-devices for centrifugal pumps are arranged to balance a portion only of the end thrust, the remaining thrust being used for any required purpose, for example balancing the weight of parts in a vertical pump, or retaining the shaft in contact with a thrust bearing. To this end, the impeller a is provided with perforations b to admit fluid to a balancing-chamber. The impeller is provided with labyrinth packings c, c<1>, of unequal mean diameter. This inequality of diameter causes the pressure in the balancing-chamber to be less than the end thrust. In a modification, the packing c' is detachably secured, so that the diameter may be varied as required.
