Abstract(s)
O crescimento global de setores como a construção, exploração mineira, transportes e Indústria Petrolífera sustenta-se cada vez mais na eficiência dos processos e na redução de custos a eles associados. Grande parte destas indústrias, acima referidas, dependem em grande parte do bom funcionamento de equipamentos óleo-hidráulicos de alta pressão. O impacto financeiro que a falha de algum destes equipamentos pode causar é de tal ordem elevado que muitas indústrias combatem este risco investindo montantes elevados em equipas de manutenção e ainda em stock exagerado de órgãos mecânicos de modo a não terem de esperar por respostas e conclusões dos fabricantes mundiais acerca da garantia que dão aos produtos fornecidos. De uma forma geral, uma bomba que possa ter um custo na ordem de algumas centenas de euros, em caso de falha faz parar um equipamento na ordem das centenas dos milhares de euros que funciona em cadeia com uma grande série de outros equipamentos que têm custos idênticos, ou seja, não compensa às empresas arriscarem a colocar em trabalho bombas hidráulicas sem terem a certeza do seu bom funcionamento. O objetivo principal deste trabalho consiste no desenvolvimento de um equipamento de testes de máquinas óleo-hidráulicas. O referido equipamento deverá permitir realizar testes a bombas óleo-hidráulicas de diversas gamas e modelos in loco. Os testes a realizar serão de pressão, caudal, temperatura, rotação, binário e contagem de partículas. O equipamento final apresentará poupanças tanto ao nível do investimento inicial, como também ao nível do seu rendimento energético quando comparado com equipamentos anteriores que atualmente se encontram no mercado. No final serão apresentados os resultados comparativos entre o novo equipamento e os equipamentos já existentes no mercado. Sublinhando a poupança efetiva e inovação associadas a esta solução.
The global growth of sectors such as construction, mining, transport and Oil Industry is increasingly based on processes efficiency and cost reduction associated with them. Many of these industries, referred to above, rely heavily on the proper functioning of high pressure oil-hydraulic equipment. The financial impact that the failure of one of these equipments can cause is so high that many industries combat this risk by investing high amounts of money in maintenance teams and in exaggerated stock of mechanical spare parts so that they do not have to wait from manufacturers answers and conclusions from the guarantee they give to the products supplied. Generally, a pump that can cost around some hundreds of euros, in case of failure makes a stop of the equipment in the order of some hundreds of thousands euros that works together with a large series of other equipments that have identical costs, in conclusion, it does not compensate to the companies the risk of having hydraulic pumps into work without being sure of their proper functioning. The main objective of this work is the development of a high efficiency oil-hydraulic bench machine. This equipment should allow the testing of oil-hydraulic pumps of various ranges and models in loco. The tests to be performed will be pressure, flow, temperature, rotation, torque and particle counting. The final equipment will reveal savings both at the initial investment level and at the level of its running energy efficiency when compared to previous equipment currently on the market. At the end, the comparative results will be presented between the new equipment and the equipment already on the market emphasizing the effective savings and innovation associated with this solution.
