Example Embodiment

[0037]为了使本领域的人员更好地理解本发明方案，下面将结合本发明实施方式中的附图，对本发明具体实施方式中的技术方案进行清楚、完整地描述。

[0038]如图1所示，一种电磁泵100，包括泵体11、绕组12、若干个外铁芯13、内铁芯14和泵沟机构15。泵体11形成有第一容纳空间。绕组12至少部分设置在第一容纳空间中，绕组12至少部分设置在外铁芯13上，用于输送电流。若干个外铁芯13至少部分设置在第一容纳空间中，内铁芯14也至少部分设置在第一容纳空间中。若干个外铁芯13均至少部分围绕内铁芯14设置，从而使外铁芯13和内铁芯14之间通过绕组12中的电流产生磁场，进而实现电磁感应。泵沟机构15至少部分设置在第一容纳空间中并至少部分设置在外铁芯13和内铁芯14之间，用于作为液态金属的流动的通道。具体的，绕组12通电后，外铁芯13和内铁芯14之间产生的磁场与泵沟机构15内的液态金属作用产生感生电流，泵沟机构15中的液态金属即成为载流导体，从而使液态金属与磁场作用产生电磁力，进而驱动液态金属定向流动。

[0039]如图1和图2所示，作为一种实现方式，泵沟机构15包括流通通道151、泵沟壁152和保护层153。泵沟壁152包括第一泵沟壁1521和第二泵沟壁1522，流通通道151设置在第一泵沟壁1521和第二泵沟壁1522之间，第一泵沟壁1521和第二泵沟壁1522之间的间隙即为流通通道151。保护层153包括第一保护层1531和第二保护层1532，用于提高泵沟壁152的强度，从而固定流通通道151的形状，便于液态金属的流动。泵沟壁152设置在第一保护层1531和第二保护层1532之间，流通通道151设置在第一保护层1531和第二保护层1532之间。具体的，第一保护层1531设置在外铁芯13和第一泵沟壁1521之间，第二保护层1532设置在内铁芯14和第二泵沟壁1522之间。即外铁芯13、第一保护层1531、第一泵沟壁1521、流通通道151、第二泵沟壁1522、第二保护层1532由外至内依次排列。在本实施方式中，泵沟壁152可以采用陶瓷材料，即泵沟壁152可以是氮化硅陶瓷，由于氮化硅陶瓷的性质稳定，不导磁、不导电，耐腐蚀，从而使泵沟壁152可以具有良好的耐腐蚀性和高强度。保护层153可以采用碳纤材料，保证泵沟壁152可以有一定的延展性，使得温度发生改变后，泵沟机构15的热胀冷...

Abstract

The invention discloses an electromagnetic pump which comprises a pump body. An inner iron core; the plurality of outer iron cores are at least partially arranged around the inner iron core; the winding is at least partially arranged on the outer iron core; the pump groove mechanism is at least partially arranged between the outer iron core and the inner iron core; the electromagnetic pump further comprises a plurality of supporting structures, and each supporting structure is arranged between every two adjacent outer iron cores. The supporting structure comprises a first support and a second support, the yoke parts of the two adjacent outer iron cores are connected through the first support, and the tooth parts of the two adjacent outer iron cores are connected through the second support; the yoke parts of the plurality of outer iron cores and the plurality of first supports form a first circular ring body, and the tooth parts of the plurality of outer iron cores and the plurality of second supports form a second circular ring body; the first circular ring body is arranged around the second circular ring body. The transformer has the beneficial effects that the plurality of second outer iron cores can be supported through the supporting structure, so that the plurality of second outer iron cores do not change under the action of magnetic pulling force.

Description

technical field [0001] The invention relates to the field of electromagnetic pumps, in particular to an induction electromagnetic pump. Background technique [0002] During the normal operation of the electromagnetic pump, the outer core part will be subjected to an inward magnetic pressure. In the case of high magnetic field strength, the value of magnetic pressure is usually very large, and the existing electromagnetic pump does not have a corresponding support structure, which makes the power of the existing electromagnetic pump small, and the operation under high power conditions will cause structural damage. Deformation greatly affects the operation of the pump. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide an electromagnetic pump that can support the outer iron core under the action of magnetic pressure. [0004] To achieve the above object, the present invention adopts the ...
