The Influence of Cavitations Phenomenon and Water Hammer in Batlava Pumping Station

Abstract

Cavitations’ phenomenon and water hammer fall in group of critical characteristics of turbo machinery and are a pernicious phenomenon that may occur during their exploitation. Water hammer appears in case when pressures change as a result of rapidly changing water flow velocity. As a preventive measure by water hammer is slowdown of the flow velocity of the water and all recommendations based on this purpose are categorized into: slowdown water flow velocity, protection from pressure drop, etc. In this paper are analyzed the phenomenon of cavitations’ and water hammer through the mathematical model and based in the calculations are taken suitable measures in order to avoid such phenomena in the main drinking water supply system for residents of the city of Prishtina, Podujeva, Fushë Kosova and Obiliqi.
