Paper Abstract

In the piping systems carrying fluids the phenomenon of cavitation may occur in a number of places. It is generated where the local pressure drops below the saturated vapour pressure. In various piping systems cavitation takes place in pumps, in cut-off fittings, regulator fittings, etc. In most cases it is detrimental. Cavitation affects the environment through noise- and vibration-related effects apart from causing physical damage of the boundary surfaces of the flow. In today's light construction buildings the vibrations may easily diffuse and this may also damage the machines and the equipment inside. Harmful vibrations arising due to cavitation may severely damage the machines, and influence their operation in a negative way. In hydraulic systems pumps are critical elements from cavitation point of view, since damage may appear in the pump on its inlet side.
