Resumo(s)
A eficiência energética é um tema crucial nos dias de hoje, pois é uma forma importante
de combate às alterações climáticas e à escassez de recursos naturais. Na indústria, qualquer
melhoria na eficiência energética pode resultar em reduções significativas no consumo de
energia e, por conseguinte, de combustíveis fósseis.
A manutenção de equipamentos é importante na melhoria da eficiência energética, pois
não se limita à reparação dos mesmos, como também garante a preservação do seu funciona-
mento adequado e consequentemente resulta numa eficiência do equipamento, ao longo da
sua vida útil, mais próxima do seu valor inicial.
Em muitas indústrias, os acionamentos eletromecânicos são elementos fundamentais
para a operação adequada e as falhas destes equipamentos resultam em perdas financeiras
decorrentes de paragens das linhas de produção. Além disso, uma manutenção adequada é
importante para garantir que o equipamento esteja em boas condições, de forma a minimizar
as suas perdas de potência e prolongar os seu tempo de vida útil.
O presente estudo foi realizado com o apoio da SEW-EURODRIVE Portugal. Foram de-
senvolvidos um modelo e um procedimento para a sua aplicação que ajudam a determinar o
rendimento de motorredutores. Foram avaliados os ganhos energéticos obtidos com a manu-
tenção adequada de motorredutores. Foi recolhida informação técnica e científica sobre as per-
das típicas de potência em cada um dos componentes destes equipamentos.
Foi realizado um estudo de caso numa empresa fabricante de bebidas onde foram ana-
lisados os consumos de equipamentos antes e depois da sua manutenção e as falhas que leva-
ram ao surgimento de perdas. Adicionalmente foram desenvolvidas sugestões para a melhoria
da gestão da manutenção da empresa estudada.
O modelo e o procedimento propostos poderão ser facilmente adaptados a outros tipos
de motorredutores, a outras aplicações dos mesmos e a outros equipamentos industriais.
Energy efficiency is a crucial topic in today's world, as it is an important way to combat climate change and the scarcity of natural resources. In the industry, any improvement in en- ergy efficiency can result in significant reductions in energy consumption and, consequently, fossil fuel consumption. Equipment maintenance is important in improving energy efficiency, as it not only in- volves repairing the equipment, but also ensures the preservation of their proper functioning, thereby resulting in equipment efficiency over its lifespan closer to its original value. In many industries, electromechanical drives are fundamental elements for proper operation, and fail- ures of these equipment lead to financial losses due to production line stoppages. Further- more, proper maintenance is essential to ensure that the equipment is in good condition, min- imizing power losses and extending its useful lifespan. This study was conducted with the support of SEW-EURODRIVE Portugal. A model and a procedure were developed for its application, which help determine the efficiency of gear motors. The energy gains achieved through proper maintenance of gear motors were also evaluated. Technical and scientific information on typical power losses in each of the compo- nents of these devices was collected. A case study was conducted in a beverage production company, where equipment con- sumption before and after maintenance, as well as the failures that led to losses, were analysed. Additionally, suggestions were developed to improve the maintenance management of the studied company. The proposed model and procedure can be easily adapted to other types of gear motors, other applications of the same, and other industrial equipment.
