Abstract
U ovome se članku analiziraju dosadašnje spoznaje o zatvorenom pneumatskom sustavu i mogućnost njegove izvedbe. Sve činjenice govore da zatvoreni sustav ima mogućnosti uštedjeti energiju. Eksperimentalna istraživanja i teorijske analize pokazuju da se uporabom zatvorenoga pneumatskog sustava u kombinaciji sa servo-sustavima ne mijenja način rada aktuatora u odnosu na njegov rad u otvorenom sustavu. Nadalje, takav pristup ima prednosti zbog uklanjanja onečišćenja okoliša uljem, smanjuje se moguća kontaminacija pogona vlagom te se smanjuje emisija buke kao posljedica ispuštanja zraka u atmosferu.The article analyses the possibility of performance and knowledge up to this time about close circuit pneumatic systems. All facts declare that the closed circuit has the possibility for energy saving. Experimental research and theoretical analysis shows that using the closed pneumatic system combined with a servo-system does not change the performance of the actuator in relation to its performance in an open system. Furthermore, the close circuit approach offers the advantage of elimination of oil contamination from the surroundings, reduction of the effects of moisture contamination and reduction of noise emission from exhaust flows to the atmosphere
