Description

Technical Field

[0001] This utility model relates to the field of vertical pump technology, and in particular to a vertical pump structure. Background Technology

[0002] Vertical pumps, also known as submersible slurry pumps, are centrifugal pumps used to transport abrasive solid particles and high-concentration slurries. They feature a vertical cantilever structure, a single pump casing design, a double-suction semi-open impeller, and wear-resistant metal or rubber materials. Rubber lining of the flow parts allows them to withstand corrosive conditions. They do not require shaft seal water during operation and the impeller clearance can be adjusted.

[0003] As shown in the reference case "A Vertical Pump Structure" announcement number "CN222502213U", both the side filter and the bottom filter are integrated with the suction pipe. This structure can prevent the side filter and / or bottom filter from falling off due to vibration and slurry corrosion during the operation of the vertical pump, and allows the slurry or sludge to enter the suction pipe smoothly. For working conditions where there is an anti-sloshing groove at the bottom of the pit or pool, this utility model, with the bottom of the suction pipe hollowed out and the side filter installed on the side wall, can be inserted into the anti-sloshing groove to prevent the filter from shaking in the slurry and to prevent pump blockage.

[0004] According to the above references, the filter screen and bottom filter screen in the above device are integrated with the suction pipe. This can prevent the side filter screen or bottom filter screen from falling off due to vibration and slurry corrosion during the operation of the vertical pump. It also allows the slurry or sludge to enter the suction pipe smoothly. For working conditions where there is an anti-sloshing groove at the bottom of the pit or pool, this utility model, with a hollow bottom and a side filter screen installed on the side wall, can be inserted into the anti-sloshing groove. However, when this device is used on a vertical pump, liquid leakage is prone to occur at the connection between the vertical pump and the suction pipe, which affects the performance of the vertical pump and makes it inconvenient to effectively seal the vertical pump, thus reducing the performance of the vertical pump. Utility Model Content

[0005] Therefore, it is necessary to provide a vertical pump structure to address the problem of inconvenience in effectively sealing vertical pumps.

[0006] The pump body includes a pump body with connecting pipes installed at both ends; a sealing mechanism for effectively sealing the vertical pump is disposed between the pump body and the connecting pipes; wherein the sealing mechanism includes a connecting cylinder that is snapped between the pump body and the connecting pipes, a sealing block is fixedly connected to the middle of the outer wall of the connecting cylinder, a first sealing ring is fixedly connected to both sides of the sealing block, a first connecting ring is fixedly connected to one end of the pump body and one end of the inner wall of the connecting pipe, one end of the first sealing ring is embedded in the inner wall of the first connecting ring, and a fixing component is provided at both ends of the pump body.

[0007] In one embodiment, the sealing mechanism further includes a second sealing ring fixedly connected to both ends of the sealing block, and a second connecting ring is fixedly connected to one end of both the pump body and the inner wall of the connecting pipe, with one end of the second sealing ring embedded in the inner wall of the second connecting ring.

[0008] In one embodiment, the diameters of the second sealing ring and the second connecting ring are both larger than those of the first sealing ring and the first connecting ring.

[0009] In one embodiment, air rings are fixedly connected to both ends of the sealing block, and one end of each air ring is in contact with the pump body and the connecting pipe.

[0010] In one embodiment, sealing gaskets are fixedly connected to both ends of the outer wall of the connecting cylinder.

[0011] In one embodiment, the fixing component includes several evenly arranged fixing bolts disposed at one end of the connecting pipe, one end of the fixing bolt is fitted with a washer, and one end of the fixing bolt passes through the pump body and the connecting pipe in sequence and is threadedly connected with a nut.

[0012] In one embodiment, a spiral wound pad is provided between the pump body and the connecting pipe.

[0013] In one embodiment, the diameter of the winding pad is larger than that of the second connecting ring. Beneficial effects

[0014] 1. In the above-mentioned vertical pump structure, the two ends of the connecting cylinder penetrate into the inner walls of the pump body and the connecting pipe, respectively, and contact the inner walls of the pump body and the connecting pipe through the sealing gasket on the outer wall, which can guide and seal the liquid. The two ends of the sealing block contact one end of the pump body and one end of the connecting pipe, respectively, and drive the two first sealing rings and two second sealing rings to embed into one end of the pump body and the connecting pipe, so that the first sealing ring is fitted with the first connecting ring and the second sealing ring is fitted with the second connecting ring, which can improve the connection and sealing performance between the pump body and the connecting pipe. The pump body and the connecting pipe approach each other and squeeze the sealing block. The air ring deforms accordingly, making the pump body and the connecting pipe in close contact, preventing liquid leakage during the operation of the vertical pump and improving the sealing performance of the vertical pump.

[0015] 2. The pump body and connecting pipe are connected by multiple fixing bolts and threads, which can bring the pump body and connecting pipe closer together and compress the sealing block and spiral wound gasket for a seal. During the compression process, the V-shaped protrusion design of the spiral wound gasket provides resilience, adapting to pressure fluctuations and vibrations in the pump body and connecting pipe, and sealing the flange. The gasket at one end of the fixing bolt undergoes plastic deformation under the bolt preload, ensuring the sealing surfaces fit together and reducing bolt loosening, thus improving the compression sealing effect on the sealing block and enhancing the sealing performance of the vertical pump.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The following is combined Figure 1 - Figure 5 Describe the vertical pump structure of this utility model.

[0026] In one embodiment, a vertical pump structure includes a pump body 100, with connecting pipes 200 installed at both ends of the pump body 100; a sealing mechanism 300, which can effectively seal the vertical pump, is disposed between the pump body 100 and the connecting pipes 200; wherein, the sealing mechanism 300 includes a connecting cylinder 310 snapped between the pump body 100 and the connecting pipes 200, a sealing block 320 fixedly connected to the middle of the outer wall of the connecting cylinder 310, a first sealing ring 330 fixedly connected to both sides of the sealing block 320, a first connecting ring 340 fixedly connected to one end of the pump body 100 and the inner wall of the connecting pipe 200, one end of the first sealing ring 330 being embedded in the inner wall of the first connecting ring 340, and a fixing component 390 provided at both ends of the pump body 100.

[0027] It should be noted that the vertical pump with model number "IRG50-160" is made by:

[0028] Pump body 100: adopts a vertical cantilever design, with the inlet and outlet diameters being the same and located on the same center line.

[0029] Pump casing: It serves to support and fix the pump, and is connected to the bearing bracket.

[0030] Impeller: It is directly mounted on the motor shaft and can be designed as a single stage or a multi-stage impeller. The impeller surface is smooth to reduce water flow friction loss.

[0031] Bearings: Bearings are divided into rolling and sliding types, lubricated with grease or clear oil, and the mechanical seals are made of wear-resistant metal or rubber.

[0032] Motor: Directly connected to the pump shaft, transmitting torque through a coupling.

[0033] When the vertical pump transports liquid, the sealing mechanism 300 is set between the pump body 100 and the connecting pipe 200 through the sealing block 320 on the outer wall of the connecting cylinder 310. The sealing block 320 is embedded in the first connecting ring 340 and the second connecting ring 360 through the first sealing ring 330 and the second sealing ring 350 respectively, sealing the pump body 100 and the connecting pipe 200. The fixing component 390, through the fixing bolt 391, through the cooperation of the gasket 392 and the nut 393, drives the pump body 100 and the connecting pipe 200 to squeeze the spiral wound gasket 394, which can optimize the sealing of the vertical pump without affecting the normal use of the vertical pump.

[0034] like Figure 2 , Figure 3 and Figure 4As shown, the sealing mechanism 300 also includes a second sealing ring 350 fixedly connected to both ends of the sealing block 320. A second connecting ring 360 is fixedly connected to one end of the inner wall of the pump body 100 and the connecting pipe 200. One end of the second sealing ring 350 is embedded in the inner wall of the second connecting ring 360. The diameters of the second sealing ring 350 and the second connecting ring 360 are both larger than those of the first sealing ring 330 and the first connecting ring 340. Air rings 370 are fixedly connected to both ends of the sealing block 320. One end of each air ring 370 is in contact with the pump body 100 and the connecting pipe 200. Sealing gaskets 380 are fixedly connected to both ends of the outer wall of the connecting cylinder 310.

[0035] In this embodiment, when the pump body 100 and the connecting pipe 200 are close together and clamped, the connecting cylinder 310 is inserted into the pump body 100 and the connecting pipe 200. The sealing gasket 380 seals the connection between the connecting cylinder 310 and the pump body 100 and the connecting pipe 200. The pump body 100 and the connecting pipe 200 squeeze the sealing block 320, so that the first sealing ring 330 is embedded in the inner wall of the first connecting ring 340 and the second sealing ring 350 is embedded in the inner wall of the second connecting ring 360, which can seal the pump body 100 and the connecting pipe 200. As the pump body 100 and the connecting pipe 200 are squeezed, the two air rings 370 deform and fit tightly with the pump body 100 and the connecting pipe 200, effectively sealing the vertical pump and preventing liquid leakage.

[0036] like Figure 5 As shown, the fixing component 390 includes several fixing bolts 391 evenly arranged and disposed at one end of the connecting pipe 200. One end of the fixing bolt 391 is fitted with a washer 392. One end of the fixing bolt 391 passes through the pump body 100 and the connecting pipe 200 in sequence and is threadedly connected with a nut 393. A spiral wound gasket 394 is disposed between the pump body 100 and the connecting pipe 200. The diameter of the spiral wound gasket 394 is larger than that of the second connecting ring 360.

[0037] In this embodiment, when the pump body 100 is connected to the connecting pipe 200, the spiral wound gasket 394 is placed between the pump body 100 and the connecting pipe 200. One end of the fixing bolt 391 passes through the pump body 100 and the connecting pipe 200 in sequence. The fixing bolt 391 drives the gasket 392 to contact the connecting pipe 200. As the nut 393 is threadedly connected to the fixing bolt 391, the fixing bolt 391 drives the pump body 100 and the connecting pipe 200 to move closer to each other, squeezing the spiral wound gasket 394 and the sealing block 320. This can seal the vertical pump and improve the sealing effect of the vertical pump.

[0038] Working principle: The two ends of the connecting cylinder 310 are respectively embedded into one end of the pump body 100 and the connecting pipe 200. The two sealing gaskets 380 are respectively attached to the inner walls of the pump body 100 and the connecting pipe 200. One end of multiple fixing bolts 391 passes through the pump body 100 and the connecting pipe 200 in sequence and is threadedly connected to the nut 393. As the nut 393 rotates, the fixing bolts 391 drive the gaskets 392 to bring the pump body 100 and the connecting pipe 200 closer to each other, and compress the spiral wound gasket 394 and the sealing block 320. The first sealing rings 330 at both ends of the sealing block 320 are embedded in the first connecting rings 340 on the inner walls of the pump body 100 and the connecting pipe 200, and the second sealing rings 350 are embedded in the second connecting rings 360, sealing the vertical pump. As the pump body 100 and the connecting pipe 200 are compressed, the air rings 370 at both ends of the sealing block 320 are attached to one end of the pump body 100 and the connecting pipe 200 for sealing.
