Description

Technical Field

[0001] This utility model relates to the field of gear pump technology, specifically an assembled gear pump. Background Technology

[0002] Gear pump technology primarily involves positive displacement machinery that utilizes meshing gear pairs (driving and driven gears) to transport fluids. Its core characteristics are simple structure, high reliability, and outstanding cost-effectiveness. This technology encompasses gear configuration designs, including external and internal meshing, with a focus on tooth profile optimization (such as involute and circular arc tooth profiles), clearance control (axial / radial), and material selection (metals, engineering plastics) to improve volumetric efficiency (typically exceeding 90%) and wear resistance. Modern research directions include high pressure (achieved through multi-stage gears or balanced structures), low pulsation (using helical / herringbone teeth to reduce flow fluctuations), and intelligentization (integrated sensors for real-time wear monitoring). Applications cover hydraulic systems, fuel delivery, and chemical media transport, and are particularly suitable for conditions with high viscosity or containing trace impurities.

[0003] A search revealed a gear pump (publication number CN218235466U) comprising a pump housing, gears, bushings, and two bushings respectively disposed at both ends of the gear. The bushings are housed within the pump housing and include a bushing body with two parallel shaft holes. The bushings are disposed within these shaft holes. The bushing body includes a first end face near the gear end face and a second end face away from the gear end face, both parallel to the gear end face. The second end face has an inlet and an outlet for external liquid to pass through, with the distance from the inlet to the first end face being less than the distance from the outlet to the first end face. This gear pump reduces wear on the bushings and gears during the initial use of the bushings.

[0004] However, since gear pumps are often used in applications with high viscosity or containing trace impurities, impurities gradually accumulate at the connection between the gear pump and the pipe, affecting the use of the gear pump. Utility Model Content

[0005] The purpose of this invention is to provide an assembled gear pump to address the shortcomings of the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: it includes a mounting shell, in which a gear assembly is provided, the gear assembly being capable of pumping water, and a vibration assembly is also provided in the mounting shell, the gear assembly being able to drive the vibration assembly to vibrate when it moves.

[0007] Furthermore, the mounting shell includes a protective shell, with a sealing shell at each end of the protective shell, and two connecting pipes on the protective shell.

[0008] Furthermore, the gear assembly includes a drive shaft, one end of which extends into the interior of the housing, and the other end of which is located outside the housing. The drive shaft is rotatably connected to the housing.

[0009] Furthermore, the gear assembly also includes two gear components rotatably connected to the housing, with one end of the drive shaft located inside the housing connected to a gear component, and the two gear components meshing with each other.

[0010] Furthermore, neither of the two gear components has teeth at its middle position, and each of the two gear components has a baffle at the position where teeth are not provided, with the two baffles being positioned corresponding to each other.

Detailed Implementation

[0021] 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.

[0022] Please see Figure 1-5 The present invention provides an assembled gear pump, including a mounting shell 1, a gear assembly 2 disposed inside the mounting shell 1, the gear assembly 2 being capable of pumping water, and a vibration assembly 3 disposed inside the mounting shell 1, the gear assembly 2 being capable of driving the vibration assembly 3 to vibrate when it moves.

[0023] Preferably, the mounting shell 1 includes a protective shell 11, with a sealing shell 12 at each end of the protective shell 11. The protective shell 11 is provided with two connecting pipes 13, which are positioned correspondingly and are located inside the protective shell 11. Each of the two connecting pipes 13 is provided with a connector 14 on the side away from the protective shell 11.

[0024] Preferably, the gear assembly 2 includes a drive shaft 21, one end of which extends into the interior of the housing 11 and the other end of which is located outside the housing 11. The drive shaft 21 is rotatably connected to the housing 11. By connecting the end of the drive shaft 21 located outside the housing 11 to a drive source, when the gear pump needs to be activated, the drive source is started to drive the drive shaft 21 to rotate.

[0025] Preferably, the gear assembly 2 further includes two gear components 22 rotatably connected to the housing 11. One end of the transmission shaft 21 located inside the housing 11 is connected to one gear component 22. The two gear components 22 mesh with each other. When one gear component 22 rotates, the two gear components 22 rotate synchronously when one gear component 22 rotates. The meshing rotation between the two gear components 22 creates a negative pressure state inside the housing 11. Furthermore, the arrangement of the two connecting pipes 13 allows the liquid in one connecting pipe 13 to be drawn into the other connecting pipe 13.

[0026] Preferably, neither of the two gear components 22 has teeth at the middle position, and each of the two gear components 22 has a baffle 23 at the position where no teeth are provided, with the two baffles 23 being in corresponding positions.

[0027] Preferably, the vibration assembly 3 includes two mounting pieces 31 that are respectively installed in the two connecting pipes 13. Both mounting pieces 31 are penetrated by a connecting shaft 35, and a vibration element 32 is provided at each end of the connecting shaft 35.

[0028] Preferably, a mounting component 31 is provided with two spring telescopic components 33. The output ends of the two spring telescopic components 33 are fixedly connected to a fixed plate 34. The fixed plate 34 is fixedly mounted on the connecting shaft 35. The fixed plate 34 corresponds to the positions of the two baffles 23. When the two baffles 23 rotate, they collide and move with the fixed plate 34, causing the connecting shaft 35 to move, which in turn drives the two vibrating components 32 to move. After the collision, the two spring telescopic components 33 cause the two vibrating components 32 to continuously reset, thereby causing the two vibrating components 32 to reciprocate and vibrate.

[0029] Working principle: By connecting one end of the drive shaft 21 located outside the housing 11 to a drive source, when the gear pump needs to be activated, the drive source is started to drive the drive shaft 21 to rotate, causing one gear 22 to rotate. Due to the meshing between the two gears 22, when one gear 22 rotates, the two gears 22 rotate synchronously. The meshing rotation between the two gears 22 creates a negative pressure state inside the housing 11. The positioning of the two connecting pipes 13 allows the liquid in one connecting pipe 13 to be drawn into the other connecting pipe 13. At the same time, when the two gears 22 rotate, they drive the two baffles 23 to rotate. When the two baffles 23 rotate, they collide and move with the fixed plate 34, causing the connecting shaft 35 to move. This moves the two vibrating elements 32. After the collision, the two spring telescopic elements 33 cause the two vibrating elements 32 to continuously reset. This causes the two vibrating elements 32 to reciprocate and vibrate, which vibrates and removes scale and debris in the two connecting pipes 13, preventing scale or impurities from accumulating and causing blockage.

[0030] 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.
