Experimental study of pumps in a pipe bench

Abstract

This paper presents an experimental study of radial flow propeller pumps in a pipe bench. For the development of the research, flow and pressure sensors are used in order to determine the fluctuations and the characteristics dynamics fluid of the pump. A control system was used using a Solid-State Relay to vary the speed of the pump and a virtual platform coupled to a data acquisition system to characterize the network. The characteristic curve of the propeller pump was obtained with a value of R2=0.97, in addition the characteristic curves of the hydraulic network for turbulent flow are calculated with the Reynolds number between 13821 and 81521. Finally, the volumetric losses are calculated in the pipe, which equals 10% for a flow of 10 l/min and as the flow increases up to 6 times the value decreases to 2%.
