Meritve proporcionalnega potnega ventila za vodno hidravliko

Nagode, Miha (author), Majdič, Franc (mentor)

Zaključna naloga predstavlja karakterizacijo proporcionalnega potnega ventila za vodno hidravliko. Je plod raziskovanja uporabe vode v hidravliki, ki se je začelo leta 2010 z doktorsko nalogo Franca Majdič in nadaljnjih diplomskih in zaključnih nalog. Problem oljne hidravlike, nastopi zaradi negativnih ekoloških posledic, ki jih povzroča njena uporaba. Predstavljene so meritve trenutnega prototipa proporcionalnega potnega ventila. Proporcionalnost pomika, notranje puščanje, ∆p(Q) in Q(s) karakteristika pri različnih tlakih. Sledi analiza rezultatov in predlogi za nadaljnjo delo.

• Title: Measurement of proportional directional control valve for water hydraulics

Abstract

The final thesis represents characterization of proportional directional control valve of water hydraulics. It is a product of water usage in hydraulics research which started approximately in year 2010 based on a phD thesis written by Franc Majdič and other further diploma and final theses. The issue of oil hydraulics are the negative ecological results caused by its use. Hereby the measurements of a current prototype of the proportional directional control valve are presented; move proportionality, internal leakaging and different pressure characteristics - ∆p(Q) & Q(s). The analysis of results and proposals for further work follow.
