Title:
ANNULAR LINEAR INDUCTION PUMP HAVING AXIAL GUIDE VANES
Document Type and Number:
WIPO Patent Application WO/2022/057167
Kind Code:
A1
Abstract:
The present invention provides an annular linear induction pump having axial guide vanes. M axial guide vanes are circumferentially and uniformly arranged in a flow channel of the pump, m is the same as the number of external stators, and the length of the guide vanes is jointly determined by the number of the external stators, the central radius of the flow channel, the Reynolds number of a magnetic field and the wave number of a traveling wave magnetic field. The axial guide vanes can obviously reduce the influence of circumferential non-uniform disturbance of a magnetic field and a flow field on the stability of the flow field, such that the flow stabilizing effect is achieved, and the flow stability of a large-flow pump under eccentric working conditions is greatly improved.
