A hydraulic system is a driving or transmission system that uses high pressure hydraulic fluid to power hydraulic machinery. It refers to the transfer of energy from flow and pressure. A hydraulic pump is amechanical source of power that converts mechanical power into hydraulic energy. Cavitation is the formation of vapor cavities in a liquid that are the consequence of forces acting upon the liquid. It usually occurs when a liquid is subjected to rapid changes of pressure that cause the formation of cavities where the pressure is relatively low. In this study, a cavitation was measured when the vane pump is rotating. The rotation speed of the vane pump was tested at 1000 rpm to 5000 rpm. At that time, the temperature and pressure of eachhydraulic oil were changed and controlled. The results show that flow rate and noise are changed when cavitation occurs.
