Projeto, construção e experimentação de uma bomba de diafragma acionada à baixa rotação.

Abstract

In the current times it is important to think in save energy, be electric or originating from it burns of fuels. To use alternative energy in a rational way is a manner of saving the conventional energy produced. Another advantage in to use non conventional energy is the production in low scale disseminated in any areas. The objective of this work is to present the construction and test of a diaphragm pump. The efficiency of the diaphragm pump is evaluated by comparison with a piston pump, operating in the same conditions. For maintain the pumps in movement a paddle-wheel at several rotation levels was used. Results of the powerin the shaft of the paddle-wheel and the pumps, as well as volumetric flow and total efficiency of the pumps are presented and analyzed.
