Abstract

See full text

An impeller wake vortex dissipation device under stall condition of a mixed flow pump includes a guide vane and a wake vortex dissipation device. The pump is evenly divided into n guide vane channels by N evenly distributed guide vanes. A 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. Therefore, each wake vortex dissipation device is located in the middle and upper part of the guide vane channel and does not occupy the lower guide vane channel; the wake vortex dissipation device is provided with a dissipative hole pair, which are used to dissipate the energy of the wake vortex of the impeller.
