Investigation into the stability of hydrodynamic processes in the depth centrifugal pump and pipeline system

Abstract

The mathematical model of the geothermal system “depth centrifugal pump-pipe (pipe system)” was made to assess the characteristics of an extraction depth centrifugal pump and their correlation with impeller frequency, discharge and other system parameters. Based on this mathematical model the instability zones of the system were determined. The research showed that the natural frequency of the “depth centrifugal pump-pipe” system depends on the frequency of the rotation of impeller, discharge and other parameters.
