Shaft assemblies for lineshaft turbine pump

摘要

A lineshaft turbine pump includes a packing container having a passageway longitudinally extending therethrough. Rotatably disposed within the passageway is a packing sleeve having a channel longitudinally extending between a threaded first end and an opposing threaded second end. A threaded first end of a line shaft is loosely threaded within the second end of the packing sleeve. Disposed within the channel of the packing sleeve is a thrust shaft. The thrust shaft has a second end biased against the first end of the line shaft. A threaded second end of a drive shaft is screwed into the first end of the packing sleeve such that the drive shaft biases against the first end of the thrust shaft, thereby applying longitudinal force against the line shaft.
