Vpliv viskoznosti kapljevine na izpiranje hidravličnega sistema

Jevtić, Pavle (author), Majdič, Franc (mentor)

Zagotavljanje optimalnega delovanja hidravličnih sistemov je izjemnega pomena, saj v današnjih časih igra ključno vlogo v večini industrijskih aplikacij. Z izpiranjem hidravličnega sistema, ki sodi tako pod preventivno kot tudi kurativno vzdrževanje, odstranjujemo različne vrste nečistoč, ki predstavljajo nevarnost za njegovo delovanje. Za izpiranje se uporabljajo različne kapljevine in od njihovih lastnosti je odvisna učinkovitost ter hitrost procesa. Namen te zaključne naloge je bil določiti vpliv kapljevin različnih viskoznosti, ki se najbolj pogosto uporabljajo v hidravliki. Za analizo smo uporabili enostaven sistem, na katerem smo spremljali učinkovitost izpiranja. Ob tem smo izvedli izpiranje s tremi najbolj pogostimi hidravličnimi olji in primerjali dobljene rezultate. Definirali smo prednosti in slabosti posameznega olja in ugotovili, da je za izpiranje obravnavanega hidravličnega sistema optimalno olje viskoznosti med 46 in 68 mm2/s pri temperaturi 40 °C.

• Title: Influence of fluid viscosity on hydraulic system flushing

Abstract

Ensuring optimal operation of hydraulic systems is critical, as they play a key role in many industrial applications today. Flushing the system, which is part of preventive and curative maintenance, removes various types of contaminants that pose a threat to operation. Various fluids are used for flushing, and the speed and efficiency of the process depends on their properties. The aim of this work was to analyze the influence of different viscous fluids, which are most commonly used in hydraulics. For the analysis, we used a simple system on which we monitored the flushing efficiency. At the same time, we performed flushing with 3 of the most common hydraulic oils and compared the results. We determined the advantages and disadvantages of each oil and found that the optimal oil viscosity for flushing the given system is between 46 and 68 mm2/s at a temperature of 40 °C.
