ABSTRACT:
Throttle bushing for a large capacity volute slurry pump in which the impeller is on the end of a cantilever drive shaft a substantial distance from the bearing support for the shaft and the shaft is subject to droop by its weight and the weight of the impeller. The weight of the overhanging shaft and impeller in addition to irregular loads on the shaft gives the shaft an exponential shape. The throttle bushing is between the impeller and packing or seal and is machined to take the same shape the shaft will take under load regardless of the angular direction of the load and to clear the shaft in all conditions of droop thereof as well as gyrations which will occur from unequal loads on the impeller when the pump is starting up or operating at over-capacity.
