Abstract The internal viscous oil flow characteristics in a centrifugal pump impeller were measured experimentally.The flow separation near the blade suction surface was observed,which formed the wake at different flow rates.With the viscosity increasing,the fluid on pressure sides flowed to the impeller outlet and continued to accelerate until to the impeller outlet.The wake suction covered the entire surface,the area between the blades and near the center of the relative speed were different,they accelerated the formation separation and vortex.In order to improve the impeller for the delivery of viscous water,we must take appropriate measures to eliminate or weaken the separation of wake.The result can provide reference for further study of the viscous oil pump.

Key words： viscosity centrifugal pump internal flow field waking separation
