Abstract:
Cavitation is a common and usually undesirable phenomenon in hydraulic systems. Understanding the basics of cavitation phenomenon as well as detecting existing cavitation are important in order to prevent cavitation in hydraulic systems.
In this paper past studies of orifice cavitation are discussed and also new studies of orifice and valve cavitation with hydraulic oils are presented.
Cavitation behaviour of different kinds of orifices and a poppet valve have been studied. Studies were done with different cavitation numbers.
Rough design guidelines for reducing and preventing cavitation in orifices and valves are presented.
