INDUCTOR SCREW induction pumps

摘要

The invention relates to electrical engineering, namely to the design of inductors induction screw pumps used for pumping liquid metal in atomic engineering, chemical and metallurgical industries. The technical effect is to provide high values ​​of induction in the working gap of the pump at elevated temperatures, and simplifying the process of assembly of the inductor. Inductor helical induction pump includes means for creating a magnetic field formed as arranged circumferentially enclosed in a shell of soft magnetic material and separated by spacers of non-magnetic material of the permanent magnets of blocks each of which has a central segment, magnetized radially and two lateral segments, magnetized at an angle relative to the center, the central segments are arranged with alternating poles along the circumference. 1 ZP f ly-2-yl.
