Automatic Electro-Hydraulic System for a P.E.T. Waste Baling Press
Journal Title: HIDRAULICA - Year 2018, Vol 0, Issue 3
Abstract
Environmental protection is one of the leading factors when designing modern industrial machinery, their increased overall energy efficiency requiring the use of new industrial design concepts, smart driving circuits and digital concepts [1]. Classic industrial machinery is supposed to be changing in the next few years due to the development of INDUSTRY 4.0 concept for manufacturing technologies [1]. Improving energy efficiency, in most of the cases implies designing new driving schematics and their complexity seems to be significantly increasing. Rapid development of electronics technology and software industry supported the need for energy efficiency, but fluidic – hydraulic and pneumatic – installations are performing not so well on this field. There are known various constructive solutions for directional valves that traditional fluidic manufacturers promote, in order to improve overall energy efficiency [2], but those solutions are centered on specific industrial application of group of applications. In a narrower case, a hydraulic P.E.T. waste baling press must be optimized taking into consideration productivity, ease-of-use, flexibility, energy efficiency and reduced maintenance costs [3]. Digital hydraulics might be a solution that can meet all the above criteria, but in the case of a small capacity P.E.T. waste press, retrofitting costs depreciation is poor. In this paper the authors propose a simple and energy efficient electro-hydraulic driving system for a small capacity P.E.T. waste baling press that was modeled using FluidSIM Hydraulic software environment.
