DEVELOPMENT OF A POSITIVE-DISPLACEMENT PUMP PHASE II

DEVELOPMENT OF A POSITIVE-DISPLACEMENT PUMP PHASE II

Abstract:

A positive-displacement vane pump (pdvp) was designed, constructed and preliminary tests carried out on it in the phase I of this project. Also, the influence of clearances within the pump on the hydraulic efficiency of a pdvp was theoretically investigated in phase I, based on laminar flow within the clearances. The work in this thesis is an extension of the work in phase I. In particular, the influence of the pump clearances on the hydraulic efficiency was similarly, theoretically investigated, this time, based on turbulent flow within clearances. A more tailed experimental test was then carried out on the pdvp constructed in phase I and its performance characteristics established.
