Abstract
Tema ovog završnog rada je kavitacija vijka. Na suvremenim brodovima vijak je najrašireniji tip brodskog propulzora i gotovo jedino sredstvo poriva. Može ga se predočiti kao vijak koji na osovini okreće brodski stroj i tako okrećući se u vodi kao matici snagu brodskog stroja pretvara u kretanje, tj. ostvaruje poriv. Vijak se sastoji od glavine i dva do osam listova. Prema tehničkoj izvedbi danas je u upotrebi vijak s fiksnim krilima, zatim vijak prekretnim krilima ili vijci kojima se... More zakretanjem krila može mijenjati uspon. Svaki od navedenih vijaka ima svoje prednosti i nedostatke. Ovisno o vrsti i izvedbi vijaka javlja se rizik nastanka kavitacije koji je najveći kod visoko opterećenih vijaka odnosno vijaka koji daju vrlo veliki poriv. Svrha ovog rada je prikazati uzrok pojave kavitacije, zatim podjelu i vrste kavitacije, odnosno fizikalnu prirodu pojavljivanja. Oblici i intenzivnost kavitacije ovise o kavitacijskom broju i upadnom kutu strujanja. Na kraju rada će se prikazati oštećenja koja nastaju djelovanjem kavitacije te njihova prevencija. Less
Abstract (english)
The subject of this final work is screw cavitation. On modern ships, the screw is the most widely used type of propulsion engine and almost the only means of propagation. It can be shown as a screw that rotates the ship's machine on the axle and turning in water as a nut, the power of the ship's machine turns into movement, ie it generates a drive. The bolt consists of a head and two to eight sheets. According to the technical version, a fixed-wing bolt is now in use, then the... More twisted-bolt wedge or bolts can be changed by swinging the wings. Each of the screws mentioned has its advantages and disadvantages. Depending on the type and design of the screws, there is a risk of cavitation that is greatest in high-impact screws or screws that give a very large bend. The purpose of this work is to show the cause of the cavitation, then the division and the type of cavitation or the physical nature of the occurrence. The shape and intensity of cavitation depend on the cavitation number and the incidence of the cavity. At the end of the work, damage caused by cavitation and their prevention will be shown. Less
