Description

Technical Field

[0001] This utility model relates to a fluid transport gear pump, and more particularly to a fluid transport gear pump that can improve transport efficiency and reduce energy consumption. Background Technology

[0002] Traditional fluid transfer gear pumps, such as the one published in patent CN210565060U, include a pump body and a base. The pump body has a gear cavity and houses a main gear and a driven gear, which mesh and are driven by a rotating shaft located between the pump body and the base. The pump body consists of a cover plate, a main body, and a base plate, with the bottom connected to the base. The gear cavity extends through the main body, and the base plate has a fixed shaft inserted into a fixed hole, with the driven gear fitted around the fixed shaft. An inlet vacuum chamber and an outlet vacuum chamber are formed between the main gear, the driven gear, and the gear cavity. The cover plate has an inlet hole and an outlet hole, and the base has corresponding flow channels. The base plate has an insertion hole into which the fixed shaft can be detachably inserted. The pump's inlet and outlet holes are typically located at the top of the pump.

[0003] However, placing the inlet and outlet ports above the pump body leads to several problems. First, it easily causes air bubble trapping, affecting liquid flow and reducing efficiency. Second, purging is difficult; the air layer prevents complete liquid removal, impacting subsequent operations. Furthermore, the increased height and size of the pump body makes installation and operation more challenging. Unstable liquid flow, especially when handling high-viscosity liquids or those containing solid particles, increases friction, reduces efficiency, and accelerates wear. Overall, this design increases the operational challenges of the pump. Utility Model Content

[0004] The purpose of this invention is to provide an improved fluid transport gear pump. This pump design places the inlet and outlet ports below the pump body, effectively solving problems such as air bubble retention, air blockage, and difficulty in venting in traditional designs. Gravity-assisted discharge improves liquid flow efficiency, reduces energy consumption, and extends equipment lifespan. This design also effectively reduces space occupation, making it particularly suitable for space-constrained applications, thereby improving overall operating efficiency and stability.

[0005] To achieve the above objectives, this utility model provides a fluid transport gear pump, comprising a base assembly having a first chamber and a second chamber interconnected, an input channel and an output channel respectively formed at the connection points of the first chamber and the second chamber, an input hole communicating with the lower part of the input channel, an output hole communicating with the lower part of the output channel, a first shaft hole communicating with the first chamber, and a second shaft hole communicating with the second chamber; wherein the input hole and the output hole are located below the first chamber and the second chamber; a first shaft pivotally connected to the first shaft hole of the base assembly and rotated by a drive source; a second shaft fixedly disposed in the second shaft hole of the base assembly; a first gear housed in the first chamber of the base assembly and fixedly connected to the first shaft; a second gear housed in the second chamber of the base assembly and fixedly connected to the second shaft, the first gear and the second gear meshing and rotating to transport the liquid from the input hole to the output hole.

[0006] The connection between the inlet and outlet ports facilitates control over the direction and velocity of liquid entering and exiting the pump. Positioning the inlet and outlet ports at the bottom of the pump offers several advantages. First, gravity-assisted drainage allows the liquid to drain naturally, reducing the need for external forces (such as pump pressure) and improving efficiency. Second, this design improves fluid flow, avoiding the air bubble buildup or trapping problems that often occur with top-mounted inlet ports, making it particularly suitable for applications requiring high-efficiency liquid delivery. Furthermore, the bottom-mounted design saves vertical space, allowing for a more compact design, which is especially important for space-constrained applications.

[0054] First, it should be noted that the technical features provided by this utility model are not limited to the specific structures, uses, and applications described in the embodiments. The terminology used in the description is illustrative and descriptive language that can be understood by those skilled in the art. The directional terms such as "front, up, down, back, left, right, top, bottom, inside, and outside" mentioned in this specification are merely illustrative descriptive terms based on the normal use direction and are not intended to limit the scope of patent protection.

[0055] like Figures 1 to 7 As shown in a preferred embodiment of the present invention, the fluid transport gear pump provided by the present invention includes a base assembly 1, a first shaft 60, a second shaft 70, a first gear 80, and a second gear 90.

[0056] The seat assembly 1 includes an upper seat 10, an upper partition seat 20, an intermediate seat 30, a lower partition seat 40, and a lower seat 50. Each of the upper seat 10, upper partition seat 20, intermediate seat 30, lower partition seat 40, and lower seat 50 has four first bolt holes (unnumbered), and four first bolt members 1B pass through these first bolt holes (unnumbered). Each of the upper seat 10, upper partition seat 20, intermediate seat 30, and lower partition seat 40 has two second bolt holes (unnumbered), and two second bolt members 2B pass through these second bolt holes (unnumbered).

[0057] The upper seat 10 has a first shaft hole 11 for connecting a shaft or rotating element. The first shaft hole 11 enables the upper seat 10 to mount and support rotating elements (such as shafts or other drive elements), providing a basis for the rotational motion of the device.

[0058] The upper spacer 20 is located below the upper seat 10 and has a first shaft hole 21, an input reservoir 23, and an output reservoir 24. The first shaft hole 21 corresponds to the first shaft hole 11 of the upper seat 10, providing connection to other shafts or rotating elements. The input reservoir 23 and the output reservoir 24 are located on the bottom surface at a distance from each other and can be used to store liquid.

[0059] The intermediate seat 30 is located below the upper partition 20 and has a first chamber 31, a second chamber 32, an input channel 33, and an output channel 34. The first chamber 31 communicates with the first shaft hole 21 of the upper partition 20, and the second chamber 32 communicates with the first chamber 31. The input channel 33 and the output channel 34 are respectively formed at the edges where the first chamber 31 and the second chamber 32 communicate, and the input channel 33 and the output channel 34 communicate with the input reservoir 23 and the output reservoir 24, respectively. As a key component in the structure, the intermediate seat 30 accommodates various connecting channels and grooves. It provides space to accommodate gears and drive devices, and transmits power and fluid to different parts through its internal chambers and grooves.

[0060] The lower spacer 40 is located below the intermediate seat 30 and has a first shaft hole 41, a second shaft hole 42, an input hole 43, and an output hole 44. The first shaft hole 41 communicates with the first chamber 31 of the intermediate seat 30, the second shaft hole 42 communicates with the second chamber 32 of the intermediate seat 30, the input hole 43 communicates with the input channel 33 of the intermediate seat 30, and the output hole 44 communicates with the output channel 34 of the intermediate seat 30. The lower spacer 40 provides additional structural support and mounting points for various shaft holes and through holes that connect to the intermediate seat 30. The design of these channels helps to precisely guide the flow of transmission or fluid and ensures the coordinated operation between the upper and lower components.

[0061] The lower seat 50 is located below the lower partition 40 and has an input port 51 and an output port 52. The input port 51 communicates with the input port 43 of the lower partition 40, and the output port 52 communicates with the output port 44 of the lower partition 40. The lower seat 50 provides a channel for fluid flow, ensuring that fluid or power from the upper components can be properly distributed to other systems. As a key interface for fluid entry and exit, it coordinates the flow and transmission within the system, maintaining overall efficiency.

[0062] The first shaft 60 passes through the first shaft hole 11 of the upper seat 10, the first shaft hole 41 of the lower partition seat 40, and the first chamber 31 of the intermediate seat 30. The first shaft 60 is the main power source of the system, transmitting power to other components below through the holes and chambers of the upper seat 10, lower partition seat 40, and intermediate seat 30. As the power transmission axis, it transmits motion from the upper drive source to the lower part, thereby driving the operation of the entire device.

[0063] The second shaft 70 passes through the second shaft hole 42 of the lower partition 40 and the second chamber 32 of the intermediate seat 30. The second shaft 70 works in conjunction with the first shaft 60 and is typically a passive receiving device. Through the design of the channel and chamber between the lower partition 40 and the intermediate seat 30, it converts the power or fluid from the first shaft into other forms of motion or energy to meet the operational requirements of the mechanical system.

[0064] The first gear 80 is housed in the first chamber 31 of the intermediate seat 30 and fixedly connected to the first shaft 60. The first gear 80 is the power transmission interface between the first shaft 60 and other gear assemblies. By being fixedly connected to the first shaft 60, it transmits the rotational motion of the first shaft to the second gear, realizing the meshing between the gears and providing the required torque and speed changes during operation.

[0065] The second gear 90 is housed in the second chamber 32 of the intermediate seat 30 and fixedly connected to the second shaft 70. The first gear 80 meshes with the second gear 90. The meshing of the second gear 90 with the first gear 80 enables the conversion of power or speed. Since the second gear is fixedly connected to the second shaft 70, it will transmit power to other required components or adjust the speed through the gear transmission system, ensuring the coordinated operation of the overall mechanism.

[0066] According to the above structure, the conveying process is as follows: When the first shaft 60 is rotated by the drive source, the first shaft drives the first gear 80 fixed to it to rotate. The rotation of the first gear 80 drives the second gear 90 to rotate through meshing with it. Since the second gear 90 is fixed to the second shaft 70, when the second gear 90 rotates, the liquid in the inlet 51 is drawn in and enters the first chamber 31 through the inlet channel 33, and then flows into the second chamber 32 through the outlet channel 34. Then, the liquid is effectively conveyed to the outlet 52 by the push of the second gear 90, completing the conveying process. This series of operations achieves smooth liquid conveying and maintains a stable flow rate and volume through the meshing action of the gears.

[0067] With the above structure, when the first shaft 60 is rotated by a drive source, it drives the first gear 80 to rotate, which in turn, through meshing with the second gear 90, transports the liquid from the inlet to the outlet. Since the inlet and outlet are located at the bottom, the liquid can flow in and out more smoothly with the assistance of gravity, reducing the problems of air bubble retention and air blockage, improving transport efficiency and reducing energy consumption. Furthermore, the flow channel configuration at the bottom also helps maintain stable flow, ensuring stable flow rate and volume during liquid transport, achieving higher operating efficiency, and fulfilling the purpose of this utility model.

[0068] Placing the inlet and outlet ports at the bottom of the pump body offers several advantages over traditional designs. Firstly, this design effectively utilizes gravity to assist liquid flow, reducing the need for external driving force and lowering energy consumption. Liquid flows downwards under gravity after entering, reducing the burden on the pumping process and thus improving operating efficiency. The bottom-mounted inlet and outlet ports help prevent air bubble retention, reducing air resistance and making liquid flow more stable, further improving pump efficiency. Furthermore, this design helps ensure complete purging of the liquid inside the pump, preventing air or liquid retention, ensuring smooth liquid circulation during startup, and improving start-up speed.

[0069] Furthermore, the inlet and outlet ports at the bottom effectively reduce air bubble obstruction, lower the risk of air resistance, and improve the pump's reliability and stability. Gravity assistance makes the pump more energy-efficient, reduces the pumping load, and improves energy efficiency, making it particularly suitable for long-term operation. This design also simplifies the cleaning process, prevents solid particle deposition, reduces maintenance needs, and further enhances overall operational stability. In short, this design not only improves the pump's operating efficiency but also extends the equipment's lifespan.

[0070] In addition to the above embodiments, the present invention can also be modified as follows to achieve the same purpose.

[0071] For example, the assembly includes an upper seat and a lower seat connected below the upper seat; the upper seat includes a first chamber, a second chamber, an input channel, an output channel, and a first shaft hole, and the lower seat includes an input hole, an output hole, and a second shaft hole. By separating the upper and lower seats, precise matching of the various components can be achieved, thereby enhancing the stability and durability of the overall structure.
