Description

Technical Field

[0001] This utility model relates to the field of industrial boiler water supply technology, and in particular to a water supply pump for industrial boilers. Background Technology

[0002] Industrial boiler water supply refers to the water used for boilers to produce steam for processes, heating, or power generation, as well as the water used for boiler water treatment. Industrial boiler water supply includes boiler feedwater and boiler water treatment water. The industrial boiler water supply pump is a pump that delivers feedwater at a certain temperature from the deaerator tank to the boiler. The main function of the feedwater pump is to transport and lift water or other liquids, and it plays an important role in various occasions and fields.

[0003] Existing patent CN218991969U discloses a water pump for industrial boiler water supply. This utility model includes a water pump and a fixing ring, and further includes: a fixing rod with multiple protrusions; a fixing ring with limiting portions cooperating with each of the protrusions; a fixing hole on the fixing ring; each protrusion having a triangular structure; and a circular groove on one side of each limiting portion of the fixing ring. In the water pump for industrial boiler water supply provided by this utility model, during component assembly, after connecting both ends, the fixing rod is passed through the four fixing rings. During passage, the protrusions on the fixing rod engage with the limiting portions on the fixing rings, thus limiting the rotation of the fixing rod. This facilitates direct threaded connection between the threaded parts and the fixing rod by the installer, eliminating the need for further clamping and fixing of the fixing rod using a wrench during the threaded connection process.

[0004] However, although the existing patent CN218991969U makes it easy for installers to directly connect the threaded parts to the fixing rod without the need for a wrench to further clamp and fix the fixing rod during the threaded connection process, leakage may occur at the drainage end as the water pump is used for a longer period of time.

[0005] Therefore, we propose a water supply pump for industrial boilers. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a water supply pump for industrial boilers.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A water supply pump for industrial boilers includes a fixed base, a pump body fixedly mounted on one side of the fixed base, a water inlet end one fixedly mounted on the top of the pump body, a limiting plate mounted on the side of the water inlet end one away from the fixed base, a drain end two mounted on one side of the limiting plate, a sealing assembly mounted on one side of the drain end two, and a compression gasket mounted on one side of the drain end two.

[0008] As a further embodiment of this utility model: the extrusion pad is arranged in a ring shape at the discharge end of the second drain end, and a silicone ring is provided on the outer side of the second drain end.

[0009] As a further improvement of this utility model: a second silicone ring is provided on the inner side of the first silicone ring, and a locking ring is provided on the outer side of the second silicone ring.

[0010] As a further improvement of this utility model: a positioning hole one is fixedly provided on the inner side of one end of the locking ring, and a positioning hole two is fixedly provided on the inner side of the other end of the locking ring.

[0011] As a further improvement of this utility model: a fastening screw is provided on the inner side of the first positioning hole, and a fastening screw is provided on the inner side of the second positioning hole.

[0012] As a further improvement of this utility model: the fastening screw passes through the locking ring and is threadedly connected to the nut, and the nut is located on the outside of the locking ring.

[0013] Compared with the prior art, this utility model provides a water supply pump for industrial boilers, which has the following advantages: This invention, by installing a sealing component, allows for the locking ring to be fixed to the outside of the compression gasket when a drainage pipe needs to be connected. Silicone ring one and silicone ring two are fixed in the middle of the locking ring and the compression gasket. A fastening screw is then threaded through the locking ring and connected to the nut, causing the locking ring to tighten and compress silicone ring one, silicone ring two, and the compression gasket. This reduces the gap between the compression gasket and the drainage pipe, preventing leakage and effectively improving the device's practicality.

[0014] In this invention, the fixed base is used to fix the pump body, the water inlet end of the pump body is used to connect to the water inlet pipe, and the water outlet end of the pump body is used to connect to the water outlet pipe, which effectively improves the stability and practicality of the device.

[0015] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0020] Example: A water supply pump for industrial boilers includes a fixed base 1, a pump body 2 fixedly mounted on one side of the fixed base 1, a water inlet end 3 fixedly mounted on the top of the pump body 2, a limiting plate 4 mounted on the side of the water inlet end 3 away from the fixed base 1, a drain end 5 mounted on one side of the limiting plate 4, a sealing component mounted on one side of the drain end 5, and a compression gasket 6 mounted on one side of the drain end 5.

[0021] like Figures 1-4As shown, the compression pad 6 is arranged in a ring at the discharge end of the drain end 5. A silicone ring 7 is arranged on the outer side of the drain end 5, and a silicone ring 8 is arranged on the inner side of the silicone ring 7. A locking ring 9 is arranged on the outer side of the silicone ring 8. A positioning hole 10 is fixedly arranged on the inner side of one end of the locking ring 9, and a positioning hole 11 is fixedly arranged on the inner side of the other end of the locking ring 9. A fastening screw 12 is arranged on the inner side of the positioning hole 10, and a fastening screw 12 is arranged on the inner side of the positioning hole 11. The fastening screw 12 passes through the locking ring 9 and is threadedly connected to the nut 13. The nut 13 is located on the outer side of the locking ring 9. When using a water pump for boiler water supply, the mounting base 1 is used to fix the pump body 2. The inlet end 3 of the pump body 2 is used to connect to the inlet pipe, and the drain end 5 of the pump body 2 is used to connect to the drain pipe. When it is necessary to connect to the drain pipe, the locking ring 9 can be fixed to the outside of the compression pad 6, and the silicone ring 7 and silicone ring 8 can be fixed in the middle of the locking ring 9 and the compression pad 6. Then, the fastening screw 12 passes through the locking ring 9 and is threaded to the nut 13, so that the locking ring 9 tightens and compresses the silicone ring 7, silicone ring 8 and compression pad 6, thereby reducing the gap between the compression pad 6 and the drain pipe and preventing leakage.

[0022] Working principle: When using the water pump for industrial boiler water supply, the mounting base 1 is used to fix the pump body 2. The inlet end 3 of the pump body 2 is used to connect the inlet pipe, and the drain end 5 of the pump body 2 is used to connect the drain pipe. When it is necessary to connect the drain pipe, the locking ring 9 can be fixed to the outside of the compression gasket 6, and the silicone ring 7 and silicone ring 8 can be fixed in the middle of the locking ring 9 and the compression gasket 6. Then, the fastening screw 12 passes through the locking ring 9 and is threaded to the nut 13, so that the locking ring 9 tightens and compresses the silicone ring 7, silicone ring 8 and compression gasket 6 to reduce the gap between the compression gasket 6 and the drain pipe and prevent leakage.
