Ativação e realização de atividades práticas na bancada de estudos pneumáticos e compressores alternativos de duplo estágio - PN30D

Abstract

This monograph consists in the analysis of activation and implementation of practical activities in an experimental module of studies related to pneumatic and heat transfer, from the application of a test bench with an air compression device. The equipment was received by the Department of Mechanical Engineering of the Federal Technological University of Paraná - Campus Pato Branco and was produced by the enterprise Didacta Italy (S.R.L.) - Apparecchiature Didattiche Produzione. Initially were obtained the manuals and software relating to the test bench that had been lost, and performed tests to check the operation of the equipment and its possible applications. After solving these, improvements were carried out from the micromanometer differential repair that was broken and the proper tagging and enumeration of all its components and valves, as well as its cleaning. After the experimental module has been put into operation the following tests were performed: Measurement of the power absorbed by the compressor, measurement of the manometric characteristic of the compressor, measurement of the inlet air flow and distribution flow, measurement of the increase temperature caused by the compression process, measurement of the thermal power to be removed to cool down the compressed air, measurement of the flow of compressed air in 3 different devices of reduced section, measurement of the pressure drops in 5 different types of circuits. All test procedures taken in this work are listed as well as their results, followed by a brief analysis. All results were consistent with the data available in the literature, showing that the equipment has a good reliability, and can provide greater flexibility in experimental activities developed on the test bench, in possible practical lessons that may be given in the future.
