diplomsko delo Visokošolskega strokovnega študijskega programa I. stopnje Strojništvo
Abstract
Varnostni ventil je prisoten v vsakem hidravličnem sistemu, saj ščiti pred tlačno preobremenitvijo. Ker se s spreminjanjem števila zaporedno delujočih aktuatorjev spreminja tudi tlak, moramo hidravlični sistem v vsaki situaciji ustrezno tlačno zaščititi. Gre za varnostni ventil, kateremu je možno s pomočjo krmiljenja spremeniti nivo nastavljenega tlaka. Raziskali smo več konceptov rešitve problema, jih vrednotili in izbrali najprimernejšega. Pri tem so bili ključni kriteriji kompaktnost, enostavnost izdelave in cena. Izbrani koncept rešitve smo natančno dimenzionirali ter izdelali prototip in opravili meritve. Zaključili smo z ugotovitvijo pomanjkljivosti glede na meritve in montažo prototipa ter s predlogi za izboljšavo.

Secondary title: |
Development of two-level relief valve |
Secondary abstract: |
A pressure relief valve is part of every hydraulic system because it protects against pressure overload. When the actuators in the system change, the pressure also changes, so it is necessary to protect the system from the new pressure that is created. This is a pressure relief valve, that can be modified by controller to change the level of set pressure. We studied several concepts to solve the problem, evaluated them and selected the most suitable one. The main criteria were compactness, ease of manufacture and price. The selected solution concept was carefully designed, a prototype was developed and measurements were performed. We completed the identification of deficiencies in terms of measurements, installation of the prototype and suggestions for improvement. |
