Claim 0:
1. An impeller wake vortex dissipation device under stall condition of a mixed flow pump, comprising a guide vane and a wake vortex dissipation device, wherein an inside of the mixed flow pump is evenly divided into N guide vane channels by N evenly distributed guide vanes; the wake vortex dissipation device is set in each guide vane channel, and one end of the wake vortex dissipation device is fixedly connected to the inner wall of the pump body, so each wake vortex dissipation device is located in a middle and upper part of each guide vane channel and does not occupy a lower guide vane channel; and the wake vortex dissipation device is provided with a dissipative hole pair, which is used to dissipate energy of an impeller wake vortex.
