AI Technical Summary
The existing rotor end face has no slots, and the mechanical seal ring is easily worn after the rotor is loose, causing mechanical seal leakage, affecting the service life and reliability of the pump.
Multiple slots are opened on the end face of the rotor, and corresponding bosses are set on the end face of the mechanical seal ring to ensure that the mechanical seal ring can still rotate with the shaft when the rotor is loose. The connection stability is enhanced by the cooperation of the slots and bosses.
It effectively prevents the wear of the sealing ring, reduces leakage, extends the service life of the pump, and reduces the number of production shutdowns and maintenance.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pumps, in particular to a rotor with a slot. Background Art
[0002] Existing rotors lack slots on their end faces, and mechanical seal rings lack protrusions on their end faces. When the two are mounted on the shaft, the mechanical seal rings are pressed against the rotor, allowing them to rotate with the shaft. If the rotor becomes loose, the force pressing against the mechanical seal rings is lost, and the mechanical seal rings no longer rotate with the shaft. This can easily cause the mechanical seal rings to wear out, leading to mechanical seal leakage. To address this issue, this utility model proposes a rotor with slots. Utility Model Content
[0003] The utility model provides a rotor with a clamping slot, which solves the shortcomings of the prior art.
[0004] The utility model provides the following technical solutions:
[0005] A rotor with slots comprises: a plurality of slots provided on the rotor end face and a plurality of bosses installed on the end face of a mechanical seal ring, wherein the slots and bosses correspond to each other one by one and are matched with each other.
[0006] Preferably, the number of the card slots is at least 2.
[0007] Preferably, the number of the card slots is 3.
[0008] Preferably, the length of the boss is at least 3 mm.
[0009] It should be understood that the above general description and the following detailed description are merely illustrative and do not limit the present invention.
[0010] Three small grooves are opened on the end face of the rotor, and three small bosses are added to the end face of the mechanical seal ring. The three grooves correspond to the three small bosses. The rotor and the mechanical seal ring are installed on the shaft, and the three small bosses are embedded in the three small grooves. When the rotor is loose and the force pressing on the mechanical seal is gone, the mechanical seal ring continues to rotate with the rotor and the shaft by relying on the three small bosses. The mechanical seal ring will not wear out and the mechanical seal will not leak, which greatly extends the service life of the pump and reduces the number of production shutdowns and maintenance.

[0017] The embodiments of the present invention will be described below in conjunction with the accompanying drawings.
[0018] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms, "connection" and "installation" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. In addition, "communication" can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed" means that the two are connected to each other and the relative position relationship after connection remains unchanged. The directional terms mentioned in the embodiments of the present invention, such as "inside", "outside", "top", "bottom", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present invention.
[0019] Example 1
[0020] Reference Figure 1-4 As shown, the rotor 2 and the mechanical seal ring 3 are both mounted on the shaft 1, wherein the other components of the mechanical seal are not shown. A plurality of slots 4 are provided on the end face of the rotor 2. These slots are designed to correspond one to one with and fit the bosses 5 on the end face of the mechanical seal ring 3, which means that each slot can accommodate exactly one boss. This design ensures the stability and working efficiency between the rotor and the mechanical seal ring.
[0021] During implementation, the number of the slots 4 is at least 2. This design can ensure the stability and balance of the rotor during operation. The slots are evenly distributed on the end face of the rotor to maintain the dynamic balance of the rotor and avoid vibration and noise caused by uneven distribution of the slots.
[0022] Another implementation is to set the number of the slots 4 to three. The design of three slots can further enhance the stability of the rotor, while also providing a better support point for the boss on the mechanical seal ring, thereby reducing shaking during operation.
[0023] In this case, in order to ensure that the boss 5 can be firmly embedded in the slot 4, the length of the boss 5 is designed to be at least 3 mm. Such a length can ensure that the boss has sufficient contact area in the slot, provide sufficient friction, and prevent relative sliding during operation.
[0024] In general, the rotor with slots of the present invention enhances the connection stability and working efficiency between the rotor and the mechanical seal ring through a unique design. At the same time, the design is simple and easy to implement, low in cost, and has high practical and economic value. During the specific implementation process, the number of slots and bosses and the length of the bosses can be adjusted according to actual needs to achieve the best use effect.
[0025] The above are only specific implementation methods of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field can easily think of changes or replacements within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention; in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
