Abstract

The invention provides a cylinder type linear induction electromagnetic pump with an added current stabilization guide plate; the current stabilization guide plate is added in the periphery of an in-pump liquid state metal channel in the electromagnetic pump body, and extends to form a pump body electromagnetic segment so as to segment an original annular cavity into a plurality of sector channels; the current stabilization guide plate can effectively prevent and damage eddy current formation and development in the flow channel, thus allowing the metal liquid to move in the pump axial direction, preventing the metal liquid close to the pump body outlet section to form unstable flows, providing a current stabilization effect, and greatly improving the in-pump metal liquid flowing stability under different flow rates. The cylinder type linear induction electromagnetic pump can effectively solve the unstable current flow problems of an ALIP electromagnetic pump while satisfying service life and reliability requirements, and is simple in structure and stable in works.

Description

technical field [0001] The invention relates to the technical field of electromagnetic pumps, in particular to a cylindrical linear induction electromagnetic pump with additional flow-stabilizing guide plates. Background technique [0002] Electromagnetic pumps can be divided into conduction electromagnetic pumps and induction electromagnetic pumps, among which conduction electromagnetic pumps are divided into DC conduction pumps and single-phase AC conduction pumps; induction electromagnetic pumps are divided into single-phase induction and three-phase induction electromagnetic pumps , and the three-phase induction electromagnetic pumps include planar induction, cylindrical induction and spiral induction electromagnetic pumps. At present, domestic small electromagnetic pumps are developing rapidly. They are mainly used in the printing and chemical industry to transport toxic metals such as mercury and lead, and to achieve precise and continuous control in the quantitative c...
