Simulation of an Electro-Hydraulic System for a P.E.T. Waste Baling Press
Journal Title: HIDRAULICA - Year 2018, Vol 0, Issue 4
Abstract
Energy efficiency is nowadays a key factor in designing industrial machinery, where digital technologies, modeling and simulation software environments are beginning to have a deeper impact. Smart technologies have entered industrial field supporting machine design engineers to develop and optimize their technical solutions. In some cases, when energy efficiency of old machinery needs to be increased, retrofitting existing schematics is not always an easy task, instead of modifying the connections between components or replacing some of the existing components with new ones it is preferred to replace old and inefficient parts with new modular solutions. Hydraulics and pneumatics are still two types of industrial drives that are used widely, but their overall energy efficiency has not improved very much in the past years. There are conducted industrial researches having good laboratory results, but these solutions are not ready yet for the market – standardized equipment and modules being preferred. These researches are targeted not on the entire application itself but on specific functional phases or modules. In the particular case of an existing hydraulic P.E.T. waste baling press, functional cycle optimization and energy efficiency improvement can lead to entirely replacement of the hydraulic drive and control algorithm, where digital hydraulics might be taken into consideration as a modern technical solution. It must be paid attention not only to the engineering side of these improvements, but to the economical side as well because retrofitting costs depreciation is poor. In this paper, the authors propose a simple and energy efficient electro hydraulic driving system for an existing small capacity P.E.T. waste baling press that was modeled and simulated using FluidSIM Hydraulic software environment.
