LINEAR INDUCTION PUMP Russian patent published in 1994 - IPC

FIELD: pump engineering. SUBSTANCE: pump has internal core and external magnetic circuit provided with winding. Longitudinal partitions which have lengths excessing over length of the magnetic circuit, have holes and are installed in working channel. Availability of partitions in the second half of the channel provides stability of non-uniformity of speed profile when electromagnetic influence parameter R_nS>1 excesses over unit. Losses related to re-tuning of speed profile are reduced in this case. EFFECT: improved efficiency. 3 dwg
