Abstract

The invention discloses an electromagnetic pump structure, and relates to the technical field of pumps. The structure comprises an outer cylinder, an inner cylinder located in the outer cylinder, a plurality of outer iron cores located on the outer side of the outer cylinder, coil assemblies placed in grooves of the outer iron cores, and cushion blocks located between the outer cylinder and the inner cylinder and used for supporting the inner cylinder. The structure also comprises a heat insulation pad. The heat insulation pad wraps the outer side of the outer cylinder; the heat insulation padis located between the outer iron core and the outer cylinder. The outer iron core is of a long-strip-shaped structure, the axis of each coil assembly is parallel to the axis of the outer cylinder, the outer iron core is arranged in an annular array mode with the axis of the outer cylinder as the center, the two ends of the heat insulation pad are sleeved with supporting plates, the outer iron core is located between the supporting plates, and the two ends of the outer iron core are fixedly connected with the corresponding supporting plates. The heat insulation pad greatly reduces heat transferred from the outer cylinder to the coil assembly, so that the temperature of the coil assembly is reduced, and the failure rate is reduced.

Description

technical field [0001] The invention belongs to the technical field of pumps, in particular to an electromagnetic pump structure. Background technique [0002] Electromagnetic pumps are used to transfer liquid metal. Due to the high temperature of the liquid metal, the liquid metal transfers heat through the outer cylinder to the outer iron core. The temperature of the outer iron core is very high. The heat resistance of the coil on the outer iron core is very high, and the failure rate of the coil is high. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantage of high coil failure rate in the prior art, and propose an electromagnetic pump structure with low coil failure rate. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] An electromagnetic pump structure, including an outer cylinder, an inner cylinder located inside the outer cylinder, a number of o...
