Abstract

The paper presents a system of inlet pressure control in a gear pump, used at a test stand during the research conducted by means of the PIV method and discusses important requirements of this method. An electronic control system with additional equipment has been applied in the control system. It controlled a proportional throttle flow control valve built-in parallel to the charger vane pump. The paper presents preliminary results and discusses the reasons of the control error. Steps to improve the control accuracy of the inlet pressure have been proposed.
