초록

This paper presents the experimental study of the dynamic internal pressure within a vane pump. The measurement of the dynamic internal pressure acting on the line contact between the vane and the camring in a vane pump with intravanes have been investigated. The variations of the radial acting force of a vane are calculated from previously measured results of dynamic internal pressure in four chambers surrounding a vane, and the variations of the film thickness are estimated in both the rotational speed ranges from 600 to 1200 rpm and the delivery pressure ranges from 1 to 14 MPa. The experimental technic has been established to obtain the data for performance analysis, such as reaction forces between vane and camring, friction wear at the contact regions, leakage characteristics and net forces upon the pump shaft in case of the unsteady load which is forced to the intravane pressure balance type vane pump.
