CARNEIRO HIDRÁULICO ARTESANAL COM CAMPÂNULAS DE PVC E AÇO ZINCADO

Abstract

Some rural properties lack valuable resources such as water and electricity, especially those located in remote regions, limiting family subsistence and regional development. Alternative forms of renewable energy are increasingly growing, one option for water repression is the artisanal hydraulic ram, which has as its operating principle the use of the kinetic energy of water, eliminating the need for electrical energy or fossil fuels. However, the discharge flow of a homemade hydraulic ram is considered low, and there may be improvements so that it can serve properties with greater water demands. The objective of this work was to carry out a case study through the implementation of the prototype of a homemade hydraulic ram with a modified air bell and the original artisanal hydraulic ram, in two experiments installed on different rural properties. The models were initially tested at the Instituto Federal Goiano – Campus Posse and at the Tafarel farm, in order to verify the parameters of boost pressure, boost flow, pumping yield and economic yield. The factorial scheme adopted was 2x2, considering two bells made of different materials (PVC and zinc-plated steel) and two settlement heights (4 m and 6 m) and five replications. Data were analyzed, in case of significance, using the Tukey test at 5% probability. It was verified that the prototype using the zinc-plated steel bell outperformed the original in relation to the parameters of discharge flow, pressure and pumping performance.
