Description

Technical Field

[0001] The utility model relates to the technical field of double-suction pumps, and particularly relates to a double-suction pump which is convenient to connect. Background Art

[0002] A double-suction pump generally refers to a special type of pump that has two suction inlets. Such a design can bring some significant advantages, especially in applications that require high flow rates and balanced axial forces.

[0003] According to the Chinese Patent Publication No.: CN217813972U, a shock-absorbing and easily connectable double-suction pump is disclosed, which includes a pump body, an impeller, and two mounting pipes.

Detailed implementation manners

[0030] The following will, with reference to the attached drawings, elaborate on some embodiments of the present utility model. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0031] Please refer to Figures 1-8, an embodiment of the present utility model provides a double-suction pump convenient for connection, which includes a pump body 1, and transition components are connected to one end of the water inlet and the water outlet of the pump body 1 through flanges.

[0032] One end of the transition component is connected with an adjustment and fixation component, and one end of the adjustment and fixation component is fixed with a water pipe 4. As Figure 6 shown, the adjustment and fixation component includes a fixed pipe 3 located on one side of the transition pipe 2. An elastic sleeve 13 is arranged at the other end of the fixed pipe 3. The elastic sleeve 13 is divided into multiple pieces, and there are gaps between the multiple pieces. At the same time, an extension sleeve 14 is connected to one side of the elastic sleeve 13. The extension sleeve 14 is in a flat state and wraps the water pipe 4. Since the elastic sleeve 13 and the extension sleeve 14 have a certain elasticity, water pipes 4 of different sizes can be wrapped.

[0033] And after the water pipe 4 is inserted into the extension sleeve 14, the part where the water pipe 4 needs to cross the elastic sleeve 13 is required to prevent water from overflowing outward after water enters the water pipe 4.

[0034] In addition, a tightening sleeve 15 is sleeved on the upper side of the extension sleeve 14. After the water pipe 4 is inserted, the tightening sleeve 15 is fixed on the extension sleeve 14 and the water pipe 4 by bolts to improve the stability of the water pipe 4. As Figure 8 shown, an inner groove 16 is opened on the inner side of the tightening sleeve 15. When the tightening sleeve 15 is fixed, the inner wall of the inner groove 16 is attached to one side of the extension sleeve 14.

[0035] As Figure 4 shown, the transition component includes a transition pipe 2. A flange plate is installed at one end of the transition pipe 2, and the flange plate is connected to the flange plate on the pump body 1. A slot 8 is opened in the shell at one end of the transition pipe 2. And a plug board 17 is arranged on one side of the fixed pipe 3. The fixed pipe 3 and the transition pipe 2 are connected by inserting the plug board 17 into the slot 8 in a matching manner, and the connection part is hidden.

[0036] At the same time, sliding blocks 18 are arranged on the upper and lower sides of the plug board 17, and a sliding groove 9 is opened inside an annular groove 10. The sliding groove 9 is a straight groove, and annular grooves 10 are communicated and opened on both sides of the sliding groove 9. When the plug board 17 enters the slot 8, the sliding blocks 18 first enter the sliding groove 9. When the sliding blocks 18 cannot slide, the fixed pipe 3 is rotated to make the sliding blocks 18 enter the annular groove 10, so as to initially fix the fixed pipe 3. This step can be operated when the water pipe 4 is not connected to the fixed pipe 3.

[0037] Furthermore, symmetrical slide rails 5 are arranged at the other end of the transition pipe 2. A positioning plate 6 is slidably connected inside the slide rails 5. And positioning grooves 11 are opened on both sides of the fixed pipe 3. After the fixed pipe 3 is rotated, the positioning grooves 11 are located on one side of the positioning plate 6. When the positioning plate 6 slides, the positioning plate 6 is inserted into the positioning grooves 11 in a matching manner, which can strengthen the fixation of the fixed pipe 3.

[0038] A plurality of bumps 7 are provided on the inner side of the positioning plate 6, and the bumps 7 are inserted and matched with the grooves 12 formed in the positioning grooves 11, further strengthening the stability of the fixed pipe 3.

[0039] As Figure 4 shown, a lead screw 19 is rotatably arranged in the slide rail 5. By connecting the positioning plate 6 with the lead screw 19 in a threaded manner, the stability of the positioning plate 6 during movement is improved.

[0040] In summary, the working principle of a double-suction pump that is easy to connect according to an embodiment of the present invention is as follows:

[0041] Slide the slider 18 into the chute 9, rotate the fixed pipe 3 to make the slider 18 enter the annular groove 10. At this time, the positioning groove 11 is located on one side of the positioning plate 6. Rotate the lead screw 19 to insert the positioning plate 6 into the positioning groove 11. Then insert the water pipe 4 through the extension sleeve 14, so that one end of the water pipe 4 crosses the elastic sleeve 13. At this time, use the tightening sleeve 15 to fix the extension sleeve 14 and the water pipe 4. This connection method with the water pipe 4 not only improves the sealing performance and stability, but also facilitates the separation of the water pipe 4 from the pump body 1.

[0042] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
