Description

Technical Field

[0001] This utility model relates to the field of vane pump technology, specifically a vane pump with a noise reduction structure. Background Technology

[0002] The field of vane pump technology involves multiple disciplines such as fluid machinery engineering, hydraulic transmission and precision manufacturing. Its core is to achieve efficient energy conversion through the dynamic coordination of rotor, vanes and pump body.

[0003] According to the publication number CN212272342U, a vane pump with vibration reduction and noise reduction capabilities is disclosed. The pump includes a pump body, a pump cover, a rotor, and vanes. The rotor has shaft holes and vane slots, and also multiple axial through holes. Each through hole is filled with damping sound-absorbing material and fixed with adhesive. The beneficial effects of this invention are: 1) The through holes on the rotor reduce its weight, which helps to provide the natural frequency of the oil pump assembly and the rotor itself, reducing the risk of resonance; 2) The through holes on the rotor end face reduce the frictional contact area between the rotor and the pump body, and between the rotor and the pump cover during operation, reducing the loss of frictional work; 3) The damping sound-absorbing material filling the through holes of the rotor reduces the energy transmission of rotor and vane vibrations during the operation of the oil pump, and also absorbs some of the noise generated during rotor operation.

[0004] However, during the transportation of current vane pumps, since the pumps are not yet installed and therefore not sealed, dust can easily enter the interior without being noticed, leading to wear and noise during use. Utility Model Content

[0005] The purpose of this invention is to provide a vane pump with a noise reduction structure to overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mounting shell is included, a rotating component is provided inside the mounting shell, a sealing component is also provided inside the mounting shell, and two connecting pipes are included on the mounting shell, the sealing component being able to seal the two connecting pipes.

[0007] Furthermore, the mounting housing includes a protective shell, with a sealing shell on each side of the protective shell, a driving source disposed inside one of the sealing shells, the output end of the driving source extending through the protective shell, and two connecting pipes disposed on the protective shell, each of the two connecting pipes being provided with a connector.

[0008] Furthermore, the rotating assembly includes a rotor fixedly mounted at the output end of the drive source, the rotor being provided with a plurality of blade slots, each of the plurality of blade slots being provided with a first spring telescopic member, each of the plurality of first spring telescopic members being provided with a blade at its output end, and the rotor being positioned corresponding to the protective shell.

[0009] Furthermore, the protective shell is provided with two arc-shaped cavities, and the sealing component includes two barrier strips respectively arranged in the two arc-shaped cavities. Each side of the two barrier strips is provided with a counterweight, and the two counterweights close to the connecting pipe are respectively associated with a snap-fit ​​position.

[0010] Furthermore, the two snap-fit ​​components are slidably connected to the two connecting tubes in a one-to-one correspondence. Each of the two snap-fit ​​components is provided with two fixing plates, and each of the two fixing plates is provided with a second spring telescopic component. Every two second springs are fixedly installed on one of the connecting tubes.

[0011] Furthermore, each of the two connecting pipes has a mounting groove, and the ends of the two snap-fit ​​members away from the counterweight block are respectively inserted into the two mounting grooves. The ends of the two snap-fit ​​members located in the mounting grooves are respectively fixedly connected to a limiting plate, and the two limiting plates are respectively threadedly connected to two handles.

[0012] Compared with the prior art, the present invention provides a vane pump with a noise reduction structure. The rotor is driven to rotate by the start-up drive source. The vane, under centrifugal force and the setting of the first spring telescopic component, enables the suction and discharge of liquid in the protective shell. When the vane pump needs to be installed, the handle is pulled to remove the barrier strip. The barrier strip makes it difficult for dust and debris to enter the vane pump during transportation, thus protecting the inside of the vane pump and preventing wear and noise caused by dust and debris entering the vane pump.

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] Please see Figure 1-4 The present invention provides a vane pump with a noise reduction structure, including a mounting shell 1, a rotating component 2 inside the mounting shell 1, a sealing component 3 inside the mounting shell 1, and two connecting pipes 14 on the mounting shell 1. The sealing component 3 can seal the two connecting pipes 14.

[0021] Preferably, the mounting housing 1 includes a protective housing 11, with a sealing housing 12 on each side of the protective housing 11. A drive source 13 is disposed inside one of the sealing housings 12, and the output end of the drive source 13 extends into the protective housing 11. Two connecting pipes 14 are disposed on the protective housing 11, and a connector 15 is disposed on each of the two connecting pipes 14. The rotating assembly 2 includes a rotor 21 fixedly disposed at the output end of the drive source 13. The rotor 21 is provided with a plurality of blade slots 22, and a first spring telescopic member 23 is disposed in each of the plurality of blade slots 22. A blade 24 is disposed at the output end of each of the plurality of first spring telescopic members 23. The rotor 21 is positioned corresponding to the protective housing 11. The rotor 21 is driven to rotate by starting the drive source 13. The blades 24, under centrifugal force and the arrangement of the first spring telescopic members 23, enable the intake and discharge of liquid within the protective housing 11. The two connecting pipes 14 are responsible for the intake and discharge of liquid.

[0022] Preferably, the protective shell 11 has two arc-shaped cavities 25. The sealing component 3 includes two barrier strips 31 respectively disposed in the two arc-shaped cavities 25. Each side of the two barrier strips 31 is provided with a counterweight 32. The two counterweights 32 near the connecting pipe 14 are respectively positioned with a snap-fit ​​member 33. The two snap-fit ​​members 33 are respectively slidably connected in the two connecting pipes 14. Each snap-fit ​​member 33 is provided with two fixing plates 34. Each fixing plate 34 is provided with a second spring telescopic member 35. Every two second springs Fixedly mounted on a connecting pipe 14, the movement of the snap-fit ​​33 causes one counterweight 32 to no longer be limited. By setting a sliding connection between the counterweight 32 and the protective shell 11, the two counterweights 32 move closer to each other under the gravity of the counterweight 32, so that the barrier strip 31 no longer blocks the connecting pipe 14. By setting magnets between the counterweights 32, the counterweights 32 do not move away after they move closer, so that the barrier strip 31 is clamped and deformed, so that the barrier strip 31 and the protective shell 11 are interference-fitted, so that the counterweight 32 cannot move afterward.

[0023] Preferably, each of the two connecting pipes 14 has a mounting groove. The ends of the two snap-fit ​​pieces 33 away from the counterweight 32 are respectively inserted into the two mounting grooves. The ends of the two snap-fit ​​pieces 33 located in the mounting grooves are respectively fixedly connected to a limiting plate 36. The two limiting plates 36 are respectively threadedly connected to two handles 37. Due to the threaded connection between the handles 37 and the limiting plates 36, the handles 37 can be removed, so that the setting of the handles 37 will not affect the connection of the connecting piece 15.

[0024] Working principle: When the vane pump 24 needs to be installed, the handle 37 is pulled to move the limiting plate 36, which in turn moves the snap-fit ​​33, causing the two fixing plates 34 to move and the two second spring telescopic parts 35 to retract. The movement of the snap-fit ​​33 makes one counterweight 32 no longer restricted. By setting a sliding connection between the counterweight 32 and the protective shell 11, the two counterweights 32 move closer to each other under the action of their gravity, so that the barrier band 31 no longer blocks the connecting pipe 14. By setting magnets between the counterweights 32, the counterweights 32 do not move away after they are close together, so that the barrier band 31 is clamped and deformed, and the barrier band 31 is interference-fitted with the protective shell 11, so that the counterweight 32 cannot move afterward. Then, the handle 37 is turned, and due to the threaded connection between the handle 37 and the limiting plate 36, the handle 37 is removed, so that the setting of the handle 37 does not affect the connection of the connecting part 15.

[0025] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
