Respect and care for human beings is an increasingly inherent value in culture of large organizations. People and safety in the process gain attention and robustness with the aim of eliminating risk with technical development and change in the way critical equipment operates. This work has the set of guidelines that technically guide safety management systems in an industrial refrigeration process with ammonia. Standards were used national guidelines, which are of great technical value,...
Fire fighting system – SCI, is one of the main means of ensuring safety of environments that work with flammable products, considered as a system auxiliary, the system of this study is composed of an electric motor pump set and two combustion motor pumps, which are redundant. This work has as main objective prove the importance of implementing preventive and predictive maintenance plans in Fire Fighting Systems, where such systems are responsible for safety operations, people and the en...
Industrial companies are modernizing their processes, because there is a scenario of increasingly competitive market, more efficient systems will be needed to meet this new reality, in this new scenario projects are required that also follow new embedded technologies. The proposal of this article is quite challenging, as it involves the objective of show the behavior of the maintenance sector for this new reality, following the performance of these equipment over the years and present di...
This article aims to address the main factors that contribute to failures in cylinders and hydraulic pumps used for industrial maintenance and how these can be reduced or avoided. Bibliographical research was carried out from books and academic articles on hydraulic equipment, as well as operating manuals for manufacturers in this segment. A survey was also carried out within a hydraulic maintenance over a period of eight months. Through the data collected and the literature consulted, ...
This technical article presents a case study of reducing specific consumption of HFO- Heavy Fuel Oil fuel in 120 HYUNDAI HiMSEN 9H25/33 motor generators installed in two thermoelectric plants belonging to the same enterprise composed of by two engine rooms with a total electrical power generation capacity of 298 MW located in the State of Bahia, Brazil. Due to the need to reduce costs operational, in April 2013, a project was proposed that aimed to reduce consumption fuel specificat...
This article presents a case study of a maintenance plan which was implemented in the effluent treatment station of a industrial cosmetics segment in the utilities area located in Camaçari – Ba, using the Reliability Centered Maintenance (MCC) methodology. At the study, centrifugal decanter equipment was used, which had low availability and high frequency of corrective interventions. The objective of the work, was to implement a tool that allowed increasing availability and reliability...
This article studied implications of prolonged use of computers in work environments. office, such as aches and pains, and developed design requirements for accessories that meet characteristics required by users. The need for research arose due to the lack of development in similar studies, which are lacking of solutions to the problem, without developing requirements. In this way, the aim was map design requirements for equipment that improve the use of computers, using product develo...
Design solutions that facilitate home garden cultivation are lacking in today's market which number of consumers are increasing, but lack the time, space and appropriate information to keep it working well. The present work aims to present design requirements that enable the simplification of domestic garden cultivation through a mixed approach research. Wherefore, studies of the bibliographic references on the product development process were performed and related design tools were appl...
Companies seek methods and tools to improve the process productive reducing operating costs, material consumption while maintaining quality of its products. In all production processes, events occur that affect the performance of the equipment and a quick and efficient identification of the problem is necessary to reduce impacts on KPIs (Key Performance Indicator) of performance. PIMS (Plant Information Management Systems) tools help in identification of process problems and can search...
This article evaluates the integrity of industrial drainage pipes, aiming at operational reliability in complex systems. In the face of diversity of materials and fluids used, the use of Artificial Neural Networks (ANNs) emerges as a promising approach. Authors such as Elsayed and Lafraia highlight the relevance of reliability in industrial contexts. The methodology adopted it comprised the normalization of data collected from the pipes, pre-processing and exploratory analysis. The ...
