20.500.12556/RUL-95448 Nov vodno hidravlični proporcionalni potni ventil New water hydraulic proportional directional control valve Uporaba vodne hidravlike je zaradi vse večje ekološke osveščenosti čedalje bolj pogosta. Ker vodna hidravlika v razvoju še zaostaja za oljno, je razvoj novih sestavin ključnega pomena. V okviru diplomske naloge smo izboljšali koncept že obstoječega proporcionalnega potnega ventila za vodno hidravliko. Ventil je zasnovan za delovne tlake do 35 MPa in pretoke do 60 l/min pri tlačni razliki do 2 MPa. Izboljšali smo ohišje in krmilne bate ter razvili nov proporcionalni magnet. Nov ventil smo tudi izdelali. Izvedli smo še simulacijo pretoka, numerične izračune in meritve na ventilu. Uspelo nam je znatno izboljšati obstoječi ventil. Use of the water hydraulics is becoming more common, because of the increasing environmental awareness. Water hydraulics are behind in development from oil hydraulics. That is why the development of new components is essential. In this thesis we improved the concept of existing proportional directional control valve for water hydraulics. The valve is designed for operating pressures up to 35 MPa and flows of 60 l/min at the pressure difference of 2 MPa. We improved the design of the housing and control pistons. We also developed a new proportional magnet and manufactured the new valve. We did flow simulations, numerical calculations and measurements on the new valve. We have succeeded in improving the previous valve. vodna hidravlika proporcionalni magneti simulacije pretokov proporcionalni potni ventili pretočne reže numerični izračuni pretokov water hydraulics proportional magnets flow simulations proportional directional valves flow slots numerical flow calculations true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2017-09-20 14:42:34 2017-09-20 14:42:34 2022-08-10 06:21:21 0000-00-00 00:00:00 2017 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 200378 879.pdf 879.pdf 1 0612C41C92126C243238F4F02AD7DBE1 85294ff7a54232aa9781038212cd9d3fc33b36b931feb741cbd0fc80c0201045 c201ce89-a1b3-11eb-a523-00155dcfd717 20.500.12556/rul/58c83eb9-0595-4cfb-9399-3b2096cd15a9 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=104051 Fakulteta za strojništvo 0 0 0
