Abstract:The influence of the viscosity of pumped medium and shaft speeds on the performance of a centrifugal oil pump was studied experimentally. By similarity analysis method, using Reynold Number ( Re ) as the reference parameters, the performance characteristic of the centrifugal oil pump changing with the flow coefficient was analyzed. The three stages of the performance curve of centrifugal oil pumps when handling viscous liquids were summed up.
Keywords:centrifugal oil pumps  performance test  similarity analysis method
