Description

Technical Field

[0001] The utility model relates to the technical field of vertical multistage pumps, in particular to a vertical multistage pump which is easy to assemble and disassemble. Background Art

[0002] A vertical multistage pump is a type of pump that uses a multistage impeller series design. Its structural feature is that the pump shaft is perpendicular to the ground and the overall structure is vertical. This design makes the pump occupy a small area and is easy to install and maintain. The main function of a vertical multistage pump is to pressurize and transport liquids, and it is widely used in various industrial and commercial fields. The working principle of a vertical multistage pump is to drive the shaft to rotate through an electric motor, driving multiple impellers in series to rotate. Each impeller pressurizes the fluid, thereby achieving continuous pressurization and transportation of the fluid. As the fluid passes through each stage of the impeller, its pressure gradually increases and is eventually discharged from the pump outlet.

[0003] Existing vertical multistage pumps are fixed to water pipes by flanges and screws, which results in a large number of bolts being required during installation of the vertical multistage pumps, making installation and disassembly of the vertical multistage pumps inconvenient and wasting the time of the staff.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5A vertical multistage pump that is easy to disassemble and assemble comprises a vertical multistage pump body 1, a connecting pipe 2 is arranged on both sides of the vertical multistage pump body 1, a mounting seat 21 is fixedly arranged on the connecting pipe 2, a water pipe 3 is assembled on the connecting pipe 2, and a mounting block 31 is adapted to be arranged at the end of the water pipe 3 corresponding to the mounting seat 21. Positioning blocks 32 are vertically arranged downward on both sides below the mounting block 31, and positioning cavities 22 are adapted to be opened on both sides of the top of the mounting seat 21 corresponding to the positioning blocks 32, and a plurality of clamping columns 41 are inserted in the positioning cavities 22.

[0023] It is worth noting that the specific structure and working mode of the vertical multistage pump body 1 are all prior art and do not belong to the main technical problems solved in this technical solution, so they are not described in detail in this utility model. In addition, a sealing ring 34 is fixedly provided at the end of the water pipe 3. The sealing ring 34 can improve the sealing performance of the connecting pipe 2 and the water pipe 3 when connected.

[0024] The connecting pipe 2 in this device only replaces the flange, and the water flow can be realized by connecting the connecting pipe 2 with the water pipe 3. The flow direction of the water flow is the prior art, because the main technical problem solved in this technical solution is the rapid assembly of the water pipe 3, so the factors of the flow direction of the water flow are not elaborated.

[0025] Among them, both sides of the mounting seat 21 are provided with outer cavities 23 inwardly, and the inner wall of the outer cavity 23 is provided with multiple female card cavities 24 inwardly, and the female card cavities 24 all pass through the positioning cavity 22. The female card cavities 24 all pass through the positioning cavity 22, so the same female card cavity 24 is provided on both sides of the positioning cavity 22 in the mounting seat 21.

[0026] Among them, the positioning block 32 is adapted to open a sub-card cavity 33 corresponding to the mother card cavity 24, and when the positioning block 32 is located in the positioning cavity 22, the mother card cavity 24 is connected to the sub-card cavity 33. When the mother card cavity 24 is connected to the sub-card cavity 33, the card column 41 can be completely inserted into the mother card cavity 24 and the sub-card cavity 33, so that the mutual locking between the mounting seat 21 and the mounting block 31 can be achieved.

[0027] The outer cavity 23 is fitted with an outer plate 4, on which a plurality of clamping columns 41 are fixedly and vertically arranged, and the clamping columns 41 are adapted to the mother clamping cavity 24 and the child clamping cavity 33. Through the arrangement of the outer plate 4, a plurality of clamping columns 41 can be moved at the same time, so that the clamping columns 41 can be controlled.

[0028] The ends of the card posts 41 are provided with N-pole magnetic blocks, and the inner wall of the mother card cavity 24 is provided with S-pole magnetic blocks corresponding to the card posts 41. The card posts 41 can be attracted to the mother card cavity 24 by the mutual attraction between the N-pole magnetic blocks on the card posts 41 and the S-pole magnetic blocks on the inner wall of the mother card cavity 24, thereby preventing the card posts 41 from falling off from the mother card cavity 24 and the sub-card cavity 33.

[0029] Among them, buckle grooves 42 are provided on the upper side of the outer side of the outer plate 4. Through the provision of the buckle grooves 42, it is convenient for the user to buckle out the outer plate 4 in the outer cavity 23, so that the clamping column 41 can be removed.

[0030] In this embodiment, when the user needs to install the water pipe 3 on the connecting pipe 2, the positioning block 32 on the mounting block 31 can be inserted into the positioning cavity 22 on the mounting seat 21. When the positioning block 32 is fully inserted into the positioning cavity 22, the mother card cavity 24 and the child card cavity 33 therein are connected to each other, and the user can insert the outer plate 4 into the outer cavity 23 at this time. At this time, the card column 41 on the outer plate 4 will enter the mother card cavity 24 and the child card cavity 33, so that the positioning block 32 can be fixed. And through the mutual attraction between the N-pole magnetic block on the card column 41 and the S-pole magnetic block on the inner wall of the mother card cavity 24, the card column 41 can be prevented from falling off from the mother card cavity 24 and the child card cavity 33. In this way, the connection between the connecting pipe 2 and the water pipe 3 can be achieved by the card setting of the positioning block 32 and the positioning cavity 22.

[0031] Furthermore, when the user needs to remove the water pipe 3, he only needs to pull the outer plate 4 out of the outer cavity 23 through the buckle groove 42, so that the clamping column 41 can be taken out through the outer plate 4, and the connecting pipe 2 and the water pipe 3 can be removed.

[0032] In the utility model, the water pipe 3 can be installed on the connecting pipe 2 by setting the mounting seat 21 and the mounting block 31, and the positioning block 32 can be fixed by the clamping column 41, so that the water pipe 3 can be fixedly installed on the vertical multi-stage pump body 1. This installation method is very quick and convenient, and is easy for users to use.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
