Embodiment Construction

[0033] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0034] like figure 1 and figure 2 As shown, the present invention includes a coil assembly 40, a magnetic core tube 10, and an armature 20 arranged in the magnetic core tube 10. The coil assembly 40 includes a cylindrical yoke 41, a skeleton 44 installed in the yoke 41, and a The coil 42 on the skeleton 44 is filled with epoxy resin between the coil 42 and the yoke 41. The open end of the yoke 41 is sealed with a yoke piece 43. The magnetic core tube 10 includes a guide sleeve 13 and an iron core 11. The guide sleeve 13 and the iron core 11 are firmly connected and sealed with a steel ring 12. The magnetic core tube 10 runs through the yoke piece 43, the skeleton 44 and the magnetic yoke 41 in turn. One end of the magnet...

Abstract

The invention provides an electromagnet and belongs to the technical field of inductors. The electromagnet solves the problem that the existing electromagnet is poor in pressure bearing capability and easy to abrade. The electromagnet comprises a coil assembly, a magnetic core pipe and an armature arranged in the magnetic core pipe in a sliding mode. The magnetic core pipe is installed in the coil assembly in a penetration mode. The coil assembly comprises a cylindrical magnetic yoke, a framework installed in the magnetic yoke and a coil installed on the framework. A yoke piece is arranged at the opening end of the magnetic yoke in a sealing mode. The magnetic core pipe sequentially penetrates the yoke piece, the framework and the magnetic yoke, a splicing cap is installed at one end of the magnetic core pipe, an outer sleeve nut is installed at the other end of the magnetic core pipe, the splicing cap enables the coil assembly to abut against the outer sleeve nut, a flow guide hole is formed in the armature in a penetration mode, the axis of the flow guide hole is parallel to the axis of the armature, an air gap is formed between the outer diameter of the armature and the inner wall of the magnetic core pipe, and the radius of the section of the armature is identical with the thickness of the section of the coil. The electromagnet has the advantages of being high in magnetic core pipe inner cavity pressure bearing capability, large in suction force, small in power and good in corrosion resistance.
