DISCUSSION ON DESIGN SCALE OF FLOW PARAMETERS OF HELICO-AXIAL MULTIPHASE PUMP

This paper analyzes flow parameters of the helico-axial multiphase pump prototypes. Based on the comparative test, theoretical analysis and the flow angles difference along each boosting cell in a three stages helico-axial multiphase pump in different operating conditions such as inlet pressure and GVF at the suction etc. enumeration, the design features of the flow parameters of helico-multiphase multiphase pumps are discussed. Accordingly reasonable selection scales of the main design parameters are offered.
