Diseño y fabricación de un pistón y una cámara de presión de bronce al aluminio para un prototipo de bomba reciprocante

Abstract

This document contains theorical and practical information concerning the manufacture of a piston and a pressure chamber in bronze to aluminum for a prototype of reciprocating pump by means of a casting process. The theorical basement supported the study of positive displacement pumps, the general design parameters of the piston and the pressure chamber, the elements that influence the casting process, such as model construction, molding mix selection, feeding systems, molding, etc., and finally the study of Bronze Aluminum Alloy. It also synthesizes the practical experience of the process to obtain the pieces. In the results and the discussion two things were analyzed; first one the castings, their dimensions and surface finish and second the obtaining of the material, this section collects the technical memories of the tests made to the material to check their characteristics. The study allows the production of the pieces in the future. It is an important advance in our country, because the manufacture of this type of pieces has not been done previously.
