Zaznavanje vlage v hidravličnem olju

Koščak, Jošt (author), Majdič, Franc (mentor)

V hidravličnih sistemih se v hidravličnem olju pojavlja vlaga, ki se ji ne moremo izogniti. Vlaga v hidravličnem olju lahko v skrajnih primerih povzroči popolno odpoved sistema. Količino vlage v hidravličnem olju je možno meriti tudi z zaznavali vlage. V diplomskem delu so predstavljeni rezultati meritev zasičenosti hidravličnega olja z vlago. Opisani sta dve zaznavali vlage, ki smo ju uporabili za meritve. Meritve so bile izvedene za osem različnih tlakov (5 bar, 10 bar, 15 bar, 20 bar, 25 bar, 30 bar, 35 bar in 40 bar) in tri različne pretoke (1 l/min, 2 l/min in 3 l/min). Preizkusili smo tudi prototip izločevalnika vlage.

• Title: Moisture detection in hydraulic oil

Abstract

Moisture appears in hydraulic oil and there is nothing we can do to avoid it. In extreme cases, moisture in hydraulic oil can be the cause of total system failure. Moisture saturation in hydraulic oil can be measured with moisture sensors. This thesis presents the results of measurements for moisture saturation of hydraulic oil. The two selected sensors on which the tests were performed are described. The measurements were performed for eight different pressures (5 bar, 10 bar, 15 bar, 20 bar, 25 bar, 30 bar, 35 bar in 40 bar) and three different flows (1 l/min, 2 l/min in 3 l/min). We also tested the moisture seperator prototype.
