Abstract

Obtočni ventili so sestavni del filtrskih vložkov, ki se v večini primerov uporabljajo v hidravličnih napravah. Najpomembnejši parameter obtočnega ventila je odpiralni tlak, ki pa je odvisen od pretoka, kar popiše [delta]p-Q-karakteristika. V delu smo z dvema medijema, tj. z zrakom in s hidravličnim oljem, določili odpiralne tlake za že razvite obtočne ventile ter ugotavljali, kako uporabljeni medij vpliva na odpiralni tlak. Tlake smo predhodno preprosto analitično ocenili, kasneje pa smo te izračune preverili še z meritvami. Ugotovljeno je bilo, da je primerjava med zrakom in oljem možna, vendar odvisna od oblike obtočnega ventila.

Secondary title:	Testing the filter by-pass valves
Secondary abstract:	Filter by-pass valves are an essential part of filter cartridges, which, in most cases, are used in hydraulic assemblies. The main parameter of a by-pass valve is the opening pressure, which depends on the flow through the valve. The both parameters together are written in the [delta]p-Q-characteristic of the valve. In this thesis we were determining the opening pressures for already constructed valves, with two different media - air and hydraulic oil. The goal was to correlate how the media influences the opening pressure. The values were first analytically checked and also measured in real life scenario after. We could establish that a correlation between air and oil used is possible, but highly dependable on the shape of the by-pass valve itself.
