Abstract
Kljub temu, da je v hidravliki večinoma prisotno hidravlično olje, ki prav tako pripomore k mazanju kontaktnih delov, je obraba še vedno eden izmed najbolj problematičnih pojavov, ki zmanjšujejo življenjsko dobo sestavin. Zaradi tega je na trgu veliko hidravličnih olj z dodatki, ki izboljšajo lastnosti olja. Izum nanocevk iz MoS2 z ugodnimi tribološkimi lastnostmi je pokazal možnost njihove uporabe kot dodatek hidravličnim mineralnim oljem. Za ugotovitev ustreznosti uporabe nanocevk v hidravličnih sistemih smo zasnovali in izdelali miniaturno hidravlično preizkuševališče. Da so se dobljeni rezultati lahko primerjali s standardnim oljem brez dodanih nanocevk, smo izdelali dve identični preizkuševališči, ki omogočata sočasno testiranje standardnega mineralnega olja, ter mineralnega olja z nanocevkami. Preizkuševališči vsebujeta zobniško črpalko s pogonskim motorjem, varnostni ventil, potni ventil, diferencialni hidravlični valj, filter, ter rezervoar. Preizkus smo izvajali neprekinjeno 6 dni, s frekvenco preklapljanja potnega ventila 2 Hz. Med preizkusom smo spremljali tlak med P vodom črpalke in potnega ventila. Prav tako smo s pomočjo infrardeče kamere spremljali temperaturo sestavin.

Title:
Miniature hydraulic nanotubes test rig
Abstract:
Hydraulic oils are used in hydraulics also for lubrication, however the wear and tear on the components are still a major problem which affects the life of the parts. The invention of MoS2 nanotubes with beneficial tribolobical properties have shown the possibility of being very useful as additives to hydraulic oil. In order to test whether or not the additives are truly useful in hydraulic systems, we designed and built two identical miniature hydraulic test rigs so we could compare the results in which one was using regular mineral oil and the other using mineral oil with added nanotubes. The test rigs contained a gear pump with a drive motor, a safety valve, a spool valve, a differential hydraulic valve, a filter and a tank. The test was conducted for six days at a switching frequency of 2 Hz. During the test, we measured the pressure on the P line of the pump and on the A line of the spool valve. We also measured the temperature of the components with an infrared camera.
