[0014] When the diameter of the cross-section of the sealing ring is in the range of 1.8mm-2.65mm, the dimension of the guide surface along the central axial direction of the pump body is in the range of 2mm-3mm;

[0015] When the diameter of the cross-section of the sealing ring is in the range of 2.65mm-3.55mm, and the dimension of the guide surface along the central axial direction of the pump body is in the range of 2.5mm-3.5mm;

[0016] When the diameter of the cross-section of the sealing ring is in the range of 3.55mm-5.30mm, and the dimension of the guide surface along the central axial direction of the pump body is in the range of 2.5mm-4.5mm;

The pump body is installed on the outside of the bearing seat. At this time, the first L-shaped mounting groove and the second L-shaped mounting groove cooperate to form an annular sealing chamber of the sealing ring.

[0024] The first surface of the pump body is positioned opposite the second surface of the bearing housing. The first and second surfaces are located on the outer periphery of the annular sealing chamber. A groove is provided on the first surface, and a protrusion is provided on the second surface.

[0038] Figures 2-4 As shown, this embodiment provides a sealing installation structure, including a first L-shaped mounting groove 4 on the pump body 1 and a second L-shaped mounting groove 5 on the pump bearing seat 2. The first L-shaped mounting groove 4 and the second L-shaped mounting groove 5 can form an annular sealing chamber, which is used to accommodate the sealing ring 3.

[0039] The first surface 9 of the pump body 1 is positioned opposite the second surface 10 of the bearing housing 2, and the first surface 9 and the second surface 10 are located on the outer periphery of the annular sealing chamber.

[0040] In this embodiment, the first surface 9 and the second surface 10 are arranged facing each other. Specifically, the arrangement of the first surface 9 and the second surface 10 facing each other includes the first surface 9 and the second surface 10 being in contact, or as... Figure 3 As shown, there is an axial gap between the first surface 9 and the second surface 10.

[0041] A guide surface 7 is provided on the side wall of the first L-shaped mounting groove 4, and the guide surface 7 extends to the first surface 9.

[0042] A groove 13 is provided on the first surface 9, and a protrusion 12 is provided on the second surface 10. The upper surface of the protrusion 12 contacts the bottom of the groove 13. It can be understood that, in the radial direction, the protrusion 12 is located outside the second L-shaped mounting groove 5, and the groove 13 is located between the protrusion 12 and the second L-shaped mounting groove 5. The groove 13 is an annular groove with a rectangular cross-sectional shape.

[0043] In this embodiment, the pump body 1 is provided with a first L-shaped mounting groove 4, and the bearing seat 2 is provided with a second L-shaped mounting groove 5 that cooperates with the first L-shaped mounting groove 4. The pump body 1 is installed on the outside of the bearing seat 2. At this time, the first L-shaped mounting groove 4 and the second L-shaped mounting groove 5 cooperate to form an annular sealing chamber of the sealing ring 3.

[0044] The first surface 9 of the pump body 1 and the second surface 10 of the bearing seat 2 are directly opposite each other. The first surface 9 and the second surface 10 are located on the outer periphery of the annular sealing chamber. A groove 13 is provided on the first surface 9, so that a protrusion 11 is formed between the first L-shaped mounting groove 4 and the groove 13 relative to the groove 13. A protrusion 12 is provided on the second surface 10, so that an annular groove 8 is formed between the second L-shaped mounting groove 5 and the protrusion 12. After the pump body 1 and the bearing seat 2 are installed, the protrusion 11 extends into the annular groove 8.

[0045] A guide surface 7 is provided on the side wall of the first L-shaped mounting groove 4, extending to the first surface 9. During the installation of the pump body 1 and the bearing seat 2, the guide surface 7 gradually contacts and compresses the sealing ring 3. Through the slow contact between the guide surface 7 and the sealing ring 3, the sealing ring 3 will not be scratched. Moreover, during the installation process, the pump body 1 will not interfere with the position of the sealing ring 3, causing the position of the sealing ring 3 on the bearing seat 2 to change.

[0046] A groove 13 is made on the first surface 9, and a protrusion 12 is provided on the second surface 10. Under the premise of satisfying the sealing installation, the original pump body 1 and bearing seat 2 are not changed along the axial direction at this position, so that the overall structural dimensions of the pump along the axial direction remain unchanged.

[0047] At the same time, the pump body 1 and bearing housing 2 can reduce the wall thickness and weight of the product while meeting the structural strength requirements.

[0048] In this embodiment, the guide surface 7 is an inclined plane. The side of the first L-shaped mounting groove 4 includes a vertical surface along the axial direction and a guide surface 7 connected to the vertical surface. The bottom of the first L-shaped mounting groove 4, a portion of the vertical surface of the first L-shaped mounting groove 4, the bottom of the second L-shaped mounting groove 5, and at least a portion of the sidewalls of the second L-shaped mounting groove 5 form an annular sealing chamber with a sealing ring 3.

[0049] Simultaneously, the vertical portion of the first L-shaped mounting groove 4 extends to contact the inner wall of the annular groove 8. The vertical surface of the first L-shaped mounting groove 4 is connected to the guide surface 7. Specifically, the vertical surface of the first L-shaped mounting groove 4 and the guide surface 7 are connected by an arc transition. The guide surface 7 approaches the first surface 9 from the vertical surface of the first L-shaped mounting groove 4 and gradually extends radially away from the central axis of the pump body 1.

[0050] Preferably, the cross-section of the annular groove 8 is rectangular to facilitate the accommodation of the protrusion 11. At the same time, the rectangular cross-section of the annular groove 8 facilitates processing.

[0051] Preferably, the angle between the guide surface 7 and the central axis of the pump body 1 is 15°-20°. This arrangement ensures that the guide surface 7 is less likely to scratch the sealing ring 3 during the installation of the pump body 1 and the bearing housing 2. Simultaneously, the guide surface 7 does not easily interfere with the position of the sealing ring 3 and will not cause the sealing ring 3 to change position within the second L-shaped mounting groove 5. Furthermore, this arrangement ensures that the radial dimension of the protrusion 11 along the pump body 1 is not excessive, and consequently, the size of the annular groove 8 is not excessive, thus not excessively reducing the structural strength of the bearing housing 2.

[0052] When the angle between the guide surface 7 and the central axis of the pump body 1 is less than 15°, the guide surface 7 is prone to contacting the sealing ring 3 during the installation of the pump body 1, scratching the sealing ring 3. At the same time, the guide surface 7 is prone to positional interference with the sealing ring 3, causing the sealing ring 3 to change position within the second L-shaped mounting groove 5.

[0053] When the included angle between the guide surface 7 and the central axis of the pump body 1 is greater than 20°, in order to ensure the structural strength of the protrusion 11, the radial dimension of the protrusion 11 along the pump body 1 becomes larger. Correspondingly, the radial dimension of the annular groove 8 along the bearing seat 2 also becomes larger, resulting in a reduction in the structural strength of the bearing seat 2.

[0054] Preferably, the size of the guide surface 7 along the central axis of the pump body 1 is in the range of 1mm-5mm, ensuring that the size of the guide surface 7 is large enough so that the pump body 1 and bearing seat 2 will not be scratched by the sealing ring 3 and can be installed smoothly.

[0055] Preferably, the radial dimension of the guide surface 7 along the pump body 1 is 1-5mm. While meeting the guiding requirements of the sealing ring 3, it ensures that the guide surface 7 is not too large, so that the size of the annular concave groove is too large, which would affect the structural strength of the bearing seat 2.

[0056] Preferably, when the diameter of the cross-section of the sealing ring 3 is in the range of 0.5mm-1.8mm, the dimension of the guide surface 7 along the central axis of the pump body 1 is in the range of 1.5mm-2.5mm. When the diameter of the cross-section of the sealing ring 3 is in the range of 1.8mm-2.65mm, the dimension of the guide surface 7 along the central axis of the pump body 1 is in the range of 2mm-3mm.

[0057] When the diameter of the cross-section of the sealing ring 3 is in the range of 2.65mm-3.55mm, the dimension of the guide surface 7 along the central axis of the pump body 1 is in the range of 2.5mm-3.5mm.

[0058] When the diameter of the cross-section of the sealing ring 3 is in the range of 3.55mm-5.30mm, the dimension of the guide surface 7 along the central axis of the pump body 1 is in the range of 2.5mm-4.5mm.

[0059] When the diameter of the cross-section of the sealing ring 3 is in the range of 5.30mm-7.00mm, the dimension of the guide surface 7 along the central axis of the pump body 1 is in the range of 4.0mm-5.0mm.

[0060] When the diameter of the sealing ring 3 is greater than 7.00 mm, the dimension of the guide surface 7 along the central axial direction of the pump body 1 is 4.5 mm to 6 mm.

[0061] Preferably, the gap between the first surface 9 and the second surface 10 is 0.2-2 mm along the axial direction of the pump body 1.

[0062] Specifically, the dimension of the annular groove 8 along the axial direction of the bearing seat 2 is 0.2mm-2mm greater than the dimension of the guide surface 7 along the axial direction of the pump body 1, so as to ensure that the protrusion 11 is located in the annular groove 8 without interference.

[0063] Preferably, the gap between the sidewall of the groove 13 and the sidewall of the protrusion 12 is in the radial direction of the pump body 1, ranging from 0.2 mm to 2 mm.

[0064] Specifically, the radial dimension of the annular groove 8 along the bearing housing 2 is 0.2mm-2mm larger than the maximum radial dimension of the protrusion 11 along the pump body 1. This ensures that the protrusion 11 will not interfere with the pump body 1 when it is located within the annular groove 8.

[0065] In this embodiment, the guide surface 7 is an annular surface.

[0066] This embodiment also provides a pump, including a sealed mounting structure.

[0067] Preferably, the pump includes a pump body 1 and a bearing housing 2, which are fastened together by bolts.

[0068] Although the present invention has been described in detail above with general descriptions, specific embodiments, and experiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
