Air in water supply pipelines

U osnovnim se elementima analizira štetno djelovanje zračnih jastuka u vodovodnim cijevima. Prikazane su mogućnosti smanjenja štetnih djelovanja zraka u cjevovodima i vodoopskrbnim sustavima. Razmatra se odstranjenje zraka u ovisnosti o promjeru cjevovoda, brzinama punjenja cjevovoda vodom, uz prikaz mjera zaštite na osnovu provedenih praktičnih istraživanja i iskustava. Navedene su mjere kontrole i održavanja cjevovoda i crpnih sustava da bi se izbjegle pojave kavitacije.Harmful action of air pockets in water supply pipelines is analyzed in broad terms. Possibilities for reducing harmful air activity in pipelines and water supply systems are presented. The removal of air in terms of pipeline diameter and speed by which pipes are filled with water is considered, and protection measures based on practical research and past experience are presented. Measures against cavitation, as used in the inspection and maintenance of pipeline and water supply systems, are formulated
