title: ENERGY EFFICIENCY INCREASE OF ROTARY PUMP BY CONVERGENCY INTRODUCTION OF WHEEL INTER-BLADE CANAL
abstract: The paper reports the substantiation of possibility rotary pump efficiency increase in view of hydraulic losses decrease in a centrifugal wheel at the expense of convergence introduction in its inter-blade canal. Besides losses decrease in a pump the transition to a convergent flow in a centrifugal wheel allows using the model of ideal liquid flow that was impossible at liquid flow in a diffusion inter-blade canal of a wheel providing mainly for an empirical direction of investigations.
