METHOD FOR DEVELOPMENT OF CENTRIFUGAL PUMP ELECTRICAL MODEL

摘要

A method for development of a centrifugal pump electrical model involves reproduction of working flow rotary motion changed according to harmonic law with corresponding pressure, determination of corresponding active and inductive reactance. Electric current is used for reproduction of working flow and alternating electric voltage is used correspondingly for reproduction of pressure. The working flow rotary motion in the pump volute model is transformed in unidirectional current by means of m-phase rectifier, wherein m corresponds to number of impeller blades of the centrifugal pump being imitated.
