Radial Force on the Impeller of a Centrifugal Pump

Norio Uchida, Kensaku IMAICHI, Toshiaki Shirai

Abstract

Radial force of a centrifugal pump was measured, using a pump which had a device for measuring the radial force and a volute casing with an interchangeable tongue. The authors obtained some knowledge about the following items and discussed them: (1) The effect of the cross-sectional area and shape of volute tongue on the pump characteristic and radial force. (2) The characteristic of dynamic component of radial force. (3) The effect of cavitation on the radial force.
