- Resumen
In food and pharmacological industries, reducing the production time and improving the machine flexibility to be adapted to new products is a constant necessity. This generate changes on the initial working conditions for which the machines were designed. These conditions cause alterations on its dynamic response that can lead to structural failures. To detect the earliest signs of damage of the different elements of the machines makes possible to avoid unplanned downtimes and the economic losses that this involves.
The use of agitators at these types of industries is common. The agitators are rotating machines composed for one or several blades, working with different types of fluids and with a wide range of shapes. The company Vak Kimsa S.A., with 48 years of history, has consolidated its position in recent years as agitators and in-line mixing manufacturer, being a leader in the national market.
Due to the continuous development of new technologies, their integration to the industry and the increasing demand for competitive products, the company raise a long-term project to take its products to the next level. The objective is to be able to offer an agitator’s monitoring service in order to avoid unplanned downtimes. Analysing, from the vibrational point of view, the state of the elements that compose the agitator and being able to stablish alarms according to this.
The study is part of an Industrial Doctorate together with the CDIF (Centre for Industrial Diagnostics and Fluid Dynamics) of the UPC of Barcelona. The whole project has been financed by the Government of Catalonia, thanks to the funds earmarked for Industrial Doctorate projects.
The objectives and the methodology used to carry out the project are detailed in this document. The experimental test, numerical simulations and the subsequent data analysis are explained, as well as the new knowledge obtained by the company in terms of the dynamic behaviours of the agitators and the use of new technology. Finally, and based on this, the minimum hardware and software are established in order to perform the monitoring service.
