Description

Technical Field

[0001] This utility model belongs to the field of petrochemical process pumps, specifically relating to a leak-proof petrochemical process pump. Background Technology

[0002] Petroleum and its related products are one of the essential energy sources for human society. In petrochemical production, raw materials, semi-finished products and finished products are mostly liquids. During transportation, petrochemical process pumps are needed to provide the necessary pressure and flow to ensure that these liquids are transported and flow smoothly to meet the needs of the production process.

[0003] Currently, existing petrochemical process pumps require connection to pipelines responsible for transporting oil and its products during operation. To prevent pipeline leaks, sealing rings are often fitted onto the pipelines. However, this design results in an insufficiently tight connection between the sealing rings and the pipelines. Once these rings age, they can easily fall into the pump, requiring a significant amount of time for cleaning.

[0004] Therefore, to address the problem that the existing petrochemical process pumps and pipelines have insufficiently tight connections between the sealing rings and the pipelines, and that the gaps between the sealing rings and the pipelines widen after aging, making it easy for the sealing rings to fall from the pipelines into the pumps and causing complex and difficult cleaning, the existing petrochemical process pumps are improved by using clips and grooves to fix the sealing rings to the pipelines, preventing them from falling into the pumps after aging. Utility Model Content

By improving the existing petrochemical process pump, buckles and slots are added to the transport pipe connected to the pump body 1. The buckles are fixedly connected to the sealing rubber ring, and the slots are opened on the transport pipe. The buckles are engaged in the slots to fix the sealing ring to the pipe, preventing it from falling into the pump after aging.

[0026] Please see Figures 2-4 In this embodiment, the first sealing rubber ring is composed of a first support pad 6 and a first sealing ring 7 fixedly connected to the front end of the first support pad 6. A first buckle 9 is fixedly connected to the rear side of the first support pad 6. The second sealing rubber ring is composed of a second support pad 18 and a second sealing ring 19 fixedly connected to the bottom end of the second support pad 18. A second buckle 11 is fixedly connected to the top of the second support pad 18. A first connecting pipe 12 is fixedly connected to the rear side of the inlet pipe 2. A first slot 20 matching the first sealing ring 7 is opened in the first connecting pipe 12. A first groove 21 matching the first support pad 6 is opened on the front side of the first transport pipe 4. A first slot 8 is opened in the first groove 21. A second connecting pipe 13 is fixedly connected to the top end of the outlet pipe 3. The first hole 22 is provided to match the second sealing ring 19. The bottom end of the second transport pipe 5 is provided to match the second support pad 18. The second slot 10 is provided in the second slot 23. The first buckle 9 is engaged in the first slot 8 to fix the first sealing rubber ring to the front side of the first transport pipe 4. The second buckle 11 is engaged in the second slot 10 to fix the second sealing rubber ring to the front side of the second transport pipe 5.

The second slot 23 allows the second support pad 18 to be flush with the bottom end of the second transport pipe 5, which facilitates the insertion and fixing of the pipe into the second connecting pipe 13.

[0027] Please see Figures 4-6 In this embodiment, a first mounting seat 14 with a first anchoring hole 24 on its surface is fixedly connected to the first connecting pipe 12. A second mounting seat 15 is fixedly connected to the first transport pipe 4. A first screw 25 inserted into the first anchoring hole 24 is fixedly connected to the front side of the second mounting seat 15. A third mounting seat 16 with a second anchoring hole 26 on its surface is fixedly connected to the second connecting pipe 13. A fourth mounting seat 17 is fixedly connected to the second transport pipe 5. A second screw 27 inserted into the second anchoring hole 26 is fixedly connected to the bottom end of the fourth mounting seat 17. By screwing a nut onto the first screw 25 to make it fit tightly against the rear side of the first mounting seat 14, the first transport pipe 4 can be fixed inside the first connecting pipe 12. By screwing a nut onto the second screw 27 to make it fit tightly against the bottom end of the third mounting seat 16, the second transport pipe 5 can be fixed inside the second connecting pipe 13.

[0028] During operation, the operator first installs the pump body 1, then aligns the first buckle 9 with the first slot 8 and snaps it in place. The first sealing rubber ring is then fixed to the front end of the first transport pipe 4. The first transport pipe 4 is then inserted into the front end of the first connecting pipe 12, so that the first sealing ring 7 fills the first slot 20. The bottom end of the first transport pipe 4 is tightly attached to the front end of the inlet pipe 2. The first screw 25 of the second mounting base 15 passes through the first anchoring hole 24 of the first mounting base 14, and the nut is tightened to make it tightly attached to the front end of the first mounting base 14, thus completing the fixation.

[0029] Then, align the second buckle 11 with the second slot 10 and snap it in place. Fix the second sealing rubber ring to the lower side of the second transport pipe 5. Then, align the second stud on the fourth mounting base 17 with the second anchor hole 26 on the third mounting base 16. Insert the second sealing ring 19 into the second slot 22. When the fourth mounting base 17 is tightly against the third mounting base 16, tighten the nut to make it tightly against the bottom of the upper mounting base to complete the fixing.

[0030] During the startup of the pump body 1, the No. 1 sealing rubber ring can fill the gap between the No. 1 transport pipe 4 and the inlet pipe 2 to prevent leakage, while the No. 2 sealing rubber ring can fill the gap between the No. 2 transport pipe 5 and the outlet pipe 3. After the pump body 1 starts, the liquid is drawn out, enters the pump through the inlet pipe 2, and is transferred from the outlet pipe 3.

[0031] Through the above steps, the existing petrochemical process pump is improved by adding a buckle and a groove to the transport pipeline connected to the pump body 1. The buckle is fixedly connected to the sealing rubber ring, and the groove is opened on the transport pipeline. The buckle engages in the groove to fix the sealing ring to the pipeline, preventing it from falling into the pump after aging. This facilitates the replacement of the sealing ring after aging and solves the problem that the connection between the sealing ring and the pipeline in the existing petrochemical process pump is not tight enough, causing the sealing ring to fall into the pump after aging.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
