PROCESS FOR SELECTING PACKAGE-WASTE COMPACTING MODE, USING A PROPORTIONAL HYDRAULIC EQUIPMENT WITH DIGITAL INTERFACE

The invention relates to a process for selecting the waste compacting mode using a hydraulic equipment actuated by an electronic system, for selecting and displaying the working parameters. According to the invention, the process consists in selecting, by means of a selecting and displaying panel (12) some hydraulic pressure-flow rate parameters expressed as current or voltage and preset for the waste to be compacted, the selected parameters being then transmitted through an electronic system (11) to a hydraulic flow rates and pressures module comprising a pressure valve (7), a two-way flow rate regulator (8), a pressure relay (9) and a transducer subassembly (10) consisting of two relative pressure transducers and a flow rate transducer, the electronic system (11) being meant to compare the preset pressure with the pressure measured by the compacting-pressure transducer, the achieved/not achieved compaction degree of the waste to be compacted leading to switching/not switching to a higher pressure stage, subject to reaching a reference pressure, the electronic system being also able to switch it to a lower pressure stage using the flow rate regulator (8), the end of a pressing cycle being confirmed by an electric limiter (14) which stops the pressing cylinder (15) and controls the electronic system (11) as to store the pressure-flow rate parameters as reference data for a new working cycle with the same waste. Invenţia se referă la un procedeu de selectare a regimurilor de compactare a deşeurilor, folosind un echipament hidraulic acţionat printr-un sistem electronic, pentru selectarea şi afişarea parametrilor de lucru. Procedeul conform invenţiei constă din selectarea, prin intermediul unui panou (12) de selectare şi afişare, a unor parametri hidraulici de presare presiune-debit, prestabiliţi pentru un deşeu de compactat, mărimi exprimate în curent sau tensiune, parametrii selectaţi sunt apoi transmişi printr-un sistem electronic (11), la un modul hidraulic, pentru debite şi presiuni, alcătuit dintr-o supapă (7) de presiune, un regulator de debit (8) cu două căi, un releu de presiune (9) şi un subansamblu de traductori (10), cuprinzând doi traductori de presiune relativă şi un traductor de debit, sistemul electronic (11) având rolul de a compara presiunea prereglată cu cea măsurată de traductorul care măsoară presiunea de presare, iar nerealizarea/realizarea gradului de compactare pentru deşeul în lucru conduce la comutarea/necomutarea pe o treaptă de pre
