[0002] At present, electromagnetic pumps have no rotating parts, no friction loss, high efficiency, good sealing, and high operating safety factor. They can provide power for the transmission of metal solutions and are widely used in the cooling of fast neutron reactors in nuclear power plants, metal smelting and manufacturing industries.

[0003] The existing Chinese patent with announcement number CN217270662U discloses a hydraulic electromagnetic oil pump, which belongs to the field of electromagnetic pump technology. The hydraulic electromagnetic oil pump includes a pump body, a plug-in split, an armature, an electromagnetic pump sleeve, a valve core, a coil, an O-ring, a lock nut, a coil spacer, a spring, a retaining ring and a steel ball. The valve core is placed in the electromagnetic pump sleeve, and the electromagnetic pump sleeve is installed on the pump body. The guide rod on the upper part of the valve core cooperates with the inner hole of the armature. The armature is placed in the plug-in split, and the plug-in split and the pump body are sealed by an O-ring. A coil is arranged from bottom to top on the outside of the plug-in split.

[0004] With respect to the above-mentioned related technologies, it is found that when the existing plunger is in use, the armature directly collides with the oil nozzle, which not only generates noise, but also causes vibration to be transmitted to the housing.

[0005] This eventually causes wear and fatigue, which affects service life. Utility Model Content

Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents the selected embodiments of the utility model.

[0024] Reference Figure 1 , Figure 2 and Figure 3 As shown, a reciprocating motion device driven by a permanent magnet and an electromagnetic combination includes an armature 1, a push rod group 2 is installed in the middle of the armature 1, the push rod group 2 is fixed with the armature 1, a one-way valve group 3 is installed in the push rod group 2, the one-way valve group 3 is slidingly connected with the push rod group 2, an oil inlet nozzle seat sleeve 4 and an oil outlet nozzle seat sleeve 5 are symmetrically arranged on both sides of the armature 1, and buffer springs 6 connected to the oil inlet nozzle seat sleeve 4 and the oil outlet nozzle seat sleeve 5 are fixedly installed on both sides of the armature 1. By installing a push rod group 2 in the middle of the armature 1, it is ensured that the push rod group 2 can move synchronously with the armature 1 when it is easy to use. At the same time, by installing a one-way valve group 3 in the push rod group 2, it is ensured that the liquid can only flow from one side of the push rod group 2 to the other side, and cannot flow in the opposite direction, thereby avoiding backflow. At the same time, by setting the oil inlet nozzle seat sleeve 4 and the oil outlet nozzle seat sleeve 5, it is easy for the oil to stably pass through the push rod group 2 and flow out from one side to the other side. In addition, by fixing the buffer springs 6 on both sides of the armature 1, it is easy for the armature 1 to move without direct collision, thereby achieving a good buffering effect.

[0025] Reference Figure 4 and Figure 5As shown, the armature 1 includes an inner tube 11, a middle ring 12 and an outer tube 13, the middle ring 12 is arranged on the outer side of the inner tube 11, the outer tube 13 is arranged on the outer side of the middle ring 12, and the inner tube 11, the middle ring 12 and the outer tube 13 are integrally formed. The structure of the armature 1 is arranged to ensure that the inner tube 11 and the outer tube 13 are connected to each other through the middle ring 12, and the middle ring 12 arranged between the inner tube 11 and the outer tube 13 can ensure that one end of the buffer spring 6 is stably installed.

[0026] Reference Figure 3 As shown, the push rod group 2 includes an inlet push rod 21 and an outlet push rod 22, which are coaxially arranged and fixed in the inner tube 11. The structural arrangement of the push rod group 2 ensures that the inlet push rod 21 and the outlet push rod 22 cooperate to be stably installed in the armature 1 for use. The inlet push rod 21 and the outlet push rod 22 are both arranged as tubular structures, and an inner ring frame 211 is arranged in the inlet push rod 21, and the inner ring frame 211 is integrally formed with the inlet push rod 21. By arranging the inlet push rod 21 and the outlet push rod 22 as tubular structures, it is easy for oil to pass through stably for use, and at the same time, by arranging the inner ring frame 211, it is convenient to cooperate with the one-way valve group 3 for sealing.

[0027] Reference Figure 3 As shown, the one-way valve group 3 includes a valve plug 31 and a support spring 32. The valve plug 31 is slidably mounted in the inlet push rod 21, and the support spring 32 is fixedly mounted on one end of the valve plug 31. The structural setting of the one-way valve group 3 ensures that the valve plug 31 can be stably supported on the inner ring frame 211 under the action of the support spring 32 to achieve sealing during use, and the valve plug 31 can be pushed open when the oil needs to flow.

[0028] Reference Figure 3 As shown, the inner side surfaces of the oil inlet nozzle seat cover 4 and the oil outlet nozzle seat cover 5 are both provided with a limiting ring 41 corresponding to the buffer spring 6. By providing the limiting ring 41 on the inner side surfaces of the oil inlet nozzle seat cover 4 and the oil outlet nozzle seat cover 5, it is easy to stably install the other end of the buffer spring 6, ensuring that the buffer spring 6 can be stably supported and used during use. An oil outlet pipe 51 is installed in the oil outlet nozzle seat cover 5, and the oil outlet pipe 51 is sealed and fixed to the oil outlet nozzle seat cover 5. By providing the oil outlet pipe 51, it is easy to ensure that the oil is stably discharged to the outside.

[0029] Working principle: During use, oil enters steadily from the oil inlet nozzle seat sleeve, which pushes the push rod group and the armature to move, and then passes through the one-way valve group to be discharged from the oil outlet pipe on the oil outlet nozzle seat sleeve. When the armature moves to the left, the buffer spring is compressed to prevent the armature from directly colliding with the oil inlet nozzle seat sleeve to generate noise and affect the service life. When the armature moves from the leftmost side to the right side, the buffer spring is gradually released and the buffer spring is gradually compressed. The release process of the buffer spring can provide a certain amount of assistance for the movement of the armature. The gradual compression of the buffer spring at the other end can prevent the armature from directly colliding with the oil outlet nozzle seat sleeve to generate noise and affect the service life.

[0030] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
