Voda kot hidravlična tekočina v pogonsko-krmilni hidravliki - 1. del = Water as hydraulic fluid in power-control hydraulics - part 1Majdič, Franc ; Pezdirnik, Jože ; Kalin, MitjanZaradi manjših zalog in naraščajočih cen naftnih derivatov ter povečanega onesnaževanja okolja človestvo isče in vedno bolj uporablja alternativne vire kot nadomestek fosilnih surovin. Mineralno olje ... je danes zaradi visoke viskoznosti in odličnih mazalnih lastnosti najpogosteje uporabljena hidravlična tekočina, hkrati pa je sestavljena iz pretezno fosilnih surovin z vsemi zgoraj omenjenimi slabostmi. Na področju hidravlične tekočine se razvijata dve ločeni alternativi za mineralno hidravlično olje. Prva je razvoj in uvajanje biološko razgradljivega rastlinskega hidravličnega olja. To smer je pretezno ubralo nemško tržisče. Druga alternativa za zamenjavo mineralnega olja pa je "čista" voda. Na tem področju so najbolj aktivni v skandinavskih drzavah. Ker je uporaba vode v hidravliki v Sloveniji dokaj nepoznano področje, želimo v dveh prispevkih predstaviti možnost uporabe vode kot hidravlične tekočine v pogonsko-krmilni hidravliki (PKH). V tem delu se bomo osredotočili na razlike v fizikalnih lastnostih med vodo in najbolj uporabljano hidravlično tekočino doslej - mineralnim hidravličnim oljem. Preden se lotimo razvoja oziroma uporabe sestavin vodne pogonsko-krmilne hidravlike, je seveda potrebno dodobra poznati lastnosti vode, ki so bistveno drugačne od mineralnega olja in vplivajo na delovanje in lastnosti hidravličnih sestavin. V tem članku predstavljamo tudi nekatere izmed najpomembnejsih prednosti in slabosti vodne hidravlike.Source: Ventil : revija za fluidno tehniko in avtomatizacijo = journal for fluid power and automation. - ISSN 1318-7279 (Letn. 12, št. 3, 2006, str. 178-184)Type of material - article, component partPublish date - 2006Language - slovenianCOBISS.SI-ID - 9391643
