Diseño y construcción de un sistema de extracción de gases para el laboratorio de soldadura de la UPS Campus Kennedy

Abstract

The main objective of the present work was to design and to build a system of extraction of gases for the laboratory of Welding, by means of, the appropriate selection of the materials, and the selection of the extractor which fulfills the necessity of evacuation of the polluting gases. In the chapter 1 BASE TEÒRICO, the general information is gathered on Welding and its processes of Welding with basic concepts, mentioning the most important parts in this process directed to the production of polluting gases. You cause caused by the processes of Welding and the illnesses that cause for the exhibition from the gases to the environment and like they affect the human being that is inside their work place or in the laboratory in the case of the students. For the chapter 2 ANÀLISIS OF PARAMETERS FOR THE SELECTION AND CALCULATION OF THE SYSTEM DE EXTRACCIÒN OF GASES OF WELDING, the chemical composition of the air is described in normal conditions, the types and ventilation difference, the theoretical information on extraction systems, the formulas to determine the section of the ducts, lost in ducts and accessories. With the chapter 3 CÀLCULO, DESIGN AND SELECTION OF THE SYSTEM DE LOCATED EXTRACCIÒN, he/she is carried out the design of the ventilation system located by extraction, the dimensions of the ducts, the losses taken place by the accessories and the selection of the appropriate extractor for our necessity considering the solution alternatives for this extraction process. 11 In the chapter 4 FINANCIAL STUDY, it is analyzed the economic characteristics of the extraction system considering several alternatives so that the financing gotten by the part of the (Salesian Polytechnic University and of the technical School Don Bosco) it can solve which exposed preformed satisfies its necessities, to establish the final cost of the project. In the CONCLUSIONS AND RECOMMENDATIONS, we can highlight that when concluding the design you ends up determining if the objectives outlined in this investigation were completed and the restlessness outlined in the hypothesis respond. For the DESIGN OF THE SYSTEM, one carries out the drawing in three dimensions in the program Solid Wokd version 2008, and the use of the Autocad version 2008 that are good both to generate planes, based on measures provided in the previous chapters.
