摘要
In order to solve the problem of bottom-vortex in the cube type suction passage of pump 4 types of vortex-elimination devices were designed based on the vortex tubes intensity conservation theorem. To verify the validity of these devices, the test-rig was set up for experiment and the high-speed photography was applied to the flow pattern of the suction passage with different types of vortex-elimination devices. The bottom vortices in the original passage were captured successfully under different operation conditions. The effects of 4 new vortex-elimination devices on the hydraulic performance of pump system were analyzed based on the energy test. The results show that the new vortex-elimination device can eliminate the bottom vortex, the flow pattern of flare and the hydraulic performance of pump system can be improved.
