Abstract The external performance of designed axial-flow pump was tested with and without guide vane.Using the five-hole probe to measure the flow field at the inlet and outlet of guide vane through the mea-suring holes,the velocity components curves were given.The experimental results show that the power curves of pump with guide vane and without guide vane are the same.The guide vane has no influence on the performance of the impeller.At the efficiency point,the circular velocity at the outlet of guide vane is small and the recovering rotating kinetic energy of the guide vane is about 15.7% of total energy.The operating point of pump without guide vane will move to the lower flow,so the design of axial-flow pump without guide vane needs parameter compensation.Using the five-hole probe to measure the three-dimensional velocity distribution of flow field has the merits of simple operation and well applicability.The experimental data reveals the guide vane influence on performance of axial-flow pump and provides reference for the further study of flow field in axial-flow pump.
