Description

Technical Field

[0001] The utility model relates to the field of reciprocating booster pumps, in particular to a scissor pulse reciprocating booster pump. Background Technique

[0002] A booster pump is a positive displacement pump that relies on the reciprocating motion of a piston, plunger, or diaphragm within a pump cylinder to cause the working volume to change periodically. When the working volume increases, it sucks liquid (draws in air), and when it decreases, it discharges liquid (exhausts air) and boosts the pressure. Its structure includes a power end (such as components like a crankshaft and connecting rod that convert power into reciprocating motion) and a hydraulic end (components like a pump cylinder and piston that are responsible for the inlet and outlet of liquid).

[0003] In the prior art, most booster pumps generate significant pressure fluctuations during operation, resulting in unstable output pressure. This can affect the operation of systems that require stable pressure. For example, in high-precision fluid transportation or processing, pressure fluctuations can lead to unstable product quality or a decline in process accuracy. Therefore, a scissor pulse reciprocating booster pump is proposed to solve the above problems. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0032] Referring to Figures 1 to 3 , an embodiment provided by the present utility model: a scissor-type pulse reciprocating supercharger pump, including a top plate 1, two bottom plates 9 and two pump bodies 20. The top plate 1 plays an important role in carrying and connecting other components. A protective box 2 is fixedly connected to the top side of the top plate 1 to provide protection for subsequent components. A motor 3 is fixedly connected to the inner wall of the protective box 2. The motor 3 provides power for the operation of the entire supercharger pump by converting electrical energy into mechanical energy. A rotating shaft 4 is fixedly connected to the driving end of the motor 3, and it transmits the rotational power generated by the motor 3 to the transmission assembly. A transmission assembly for transmitting power is fixedly connected to the bottom side of the rotating shaft 4. The transmission assembly includes a push plate 5. The top side of the push plate 5 is fixedly connected to the bottom side of the rotating shaft 4 and makes a circular motion as the rotating shaft 4 rotates. The function of the push plate 5 is to convert the rotational motion of the rotating shaft 4 into the linear motion of the push column 6. A push column 6 is fixedly connected to the bottom side of the push plate 5. The outer part of the push column 6 is slidably connected to an open frame 7. Driven by the push plate 5, the push column 6 makes a relative sliding motion within the open frame 7;

[0033] The adjacent sides of the two side plates 8 are respectively fixedly connected to the left and right sides of the two bottom plates 9. The left and right ends of the bottom side of the top plate 1 are both fixedly connected with side plates 8, which not only provide an installation position for the pump body 20, but also together with the bottom plates 9 form the frame structure of the supercharger pump, ensuring the stability and rigidity of the entire device. A support platform 10 is fixedly connected to the top side of the two bottom plates 9. The support platform 10 is an installation platform for the limit assembly and other related components. A limit assembly for restricting subsequent components is rotatably connected to the inner wall of the support platform 10. The limit assembly includes a circular plate 12. The function of the circular plate 12 is to provide support and a rotation basis for the support column 13. The outer part of the circular plate 12 is rotatably connected to the inner wall of the support platform 10, enabling the circular plate 12 to rotate stably. A support column 13 is fixedly connected to the top side of the circular plate 12 to restrict the support column 13 and prevent it from slipping. A gear 14 is fixedly connected to the top end of the limit assembly for transmitting power.

[0034] Referring to Figure 1 , Figure 2 and Figure 4, two limit blocks 30 are slidably connected to the top end of the support platform 10 to restrict the limit blocks 30 so that the limit blocks 30 can slide horizontally left and right. A rack 15 is fixedly connected to the top side of the limit block 30 for guiding the sliding of the rack 15. The top end of the support column 13 is fixedly connected to the inside of the gear 14, and the outside of the gear 14 is meshed with the adjacent ends of the two racks 15. The force of one gear 14 is transmitted to the other gear 14 through the gear 14. The bottom side of the opening frame 7 is fixedly connected to the top side of one of the racks 15, and the force received is transmitted to one of the racks 15 through the opening frame 7. The bottom side of the opening frame 7 is slidably connected to the top side of the other rack 15 to provide support for the opening frame 7. A limit frame 16 is fixedly connected to one side of the rack 15, and the outside of the rack 15 is slidably connected to the inner wall of the limit frame 16. The limit frame 16 on one side provides a supporting force for the other rack 15 to enable it to slide stably;

[0035] Two strip-shaped openings 11 are formed on the top side of the support platform 10, and the outside of the limit block 30 is slidably connected to the inside of the strip-shaped openings 11. The limit block 30 is restricted by the formed strip-shaped openings 11 so that the limit block 30 can slide stably. A connecting plate 17 is fixedly connected to the other side of the rack 15 to transmit the sliding force to the connecting plate 17 and drive the connecting plate 17 to slide left and right. Connecting columns 18 are fixedly connected to the opposite sides of the two connecting plates 17, and piston plates 19 are fixedly connected to the opposite sides of the two connecting columns 18. The sliding force of the connecting plate 17 is transmitted to the piston plate 19 through the connecting column 18 to generate positive pressure and negative pressure.

[0036] Refer to Figure 1 and Figure 5 , the outside of the pump body 20 is fixedly connected to the inner wall of the side plate 8, and the opposite ends of the two pump bodies 20 are fixedly connected with air exchange pipes 21 for providing gas. The top end of the air exchange pipe 21 is fixedly connected with a pressurizing plate 22, and a plurality of pressurizing holes 23 are formed inside the pressurizing plate 22. The pressurizing holes 23 formed inside the pressurizing plate 22 are wider at the bottom and narrower at the top, which can improve the pressurizing efficiency. The outside of the plug plate 19 is slidably connected to the inner wall of the pump body 20 to form a negative pressure through precise combined sliding. The outside of the semi-sphere 28 is in contact with the inner wall of the pressurizing plate 22 for forming a sealed space. Connecting frames 24 are fixedly connected to both the upper and lower ends of the air exchange pipe 21, and a plurality of upright columns 25 are fixedly connected to the bottom sides of the plurality of connecting frames 24 to provide a supporting force for the connecting frames 24. A spring 26 is sleeved on the outside of the upright column 25 to restrict the spring 26 so that the spring 26 can be evenly stressed. A limit plate 27 is fixedly connected to the bottom sides of the plurality of upright columns 25, and a semi-sphere 28 is fixedly connected to the bottom sides of the four limit plates 27 to provide a supporting force for the semi-sphere 28. Sealing rings 29 are fixedly connected to both the upper and lower ends of the air exchange pipe 21 and cooperate with the semi-sphere 28 to form a sealed space.

[0037] Working principle: After the motor 3 starts, the driving end of the motor 3 drives the rotating shaft 4 to rotate. The push plate 5 at the bottom side of the rotating shaft 4 makes a circular motion along with the rotating shaft 4, and the push post 6 at the bottom side of the push plate 5 makes a relative sliding motion within the opening frame 7. The motion of the push post 6 drives the opening frame 7 to move. The opening frame 7 drives one of the racks 15 to slide, and then drives the gear 14 to rotate, and transmits the rotating force to the other rack 15, so that the two racks 15 slide in opposite directions. Then the movement of the rack 15 pushes the connecting plate 17 to slide, and then pushes the connecting post 18 to slide, and then drives the piston plate 19 to slide inside the pump body 20. At this time, when the two piston plates 19 slide towards the adjacent side, the space inside the pump body 20 increases, forming a negative pressure. At this time, the gas enters the pump body 20 through the air exchange pipe 21. When the piston plate moves to the other side, the gas inside the pump body 20 is compressed and pressurized. Thus, scissor-type pulse reciprocating suction and pressurized discharge are realized, the stability of pressurization is improved, and then the quality of the process product is improved.

[0038] When forming a negative pressure, the bottom of the air exchange pipe 21 admits air, and at the same time pushes the semi-sphere 28 at the bottom to drive the four limit plates 27 to slide and compress the spring 26, so that the spring 26 can store elastic potential energy and reset after the internal gas pressure is stable. Then when increasing the pressure, the semi-sphere 28 at the bottom of the air exchange pipe 21 remains stationary, and the semi-sphere 28 at the top opens upward to form pressurization, and cooperates with a plurality of pressurization holes 23 with a wide bottom and a narrow top opened inside the pressurization plate 22 at the top end of the air exchange pipe 21, so as to be able to perform secondary pressurization, so that the peak value of pressurization can be maintained within a certain range, thereby improving the stability of pressurization.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
