[0002] Compact high-flow gear pumps are suitable for industrial applications requiring efficient and stable delivery of large flow rates of fluids, such as petrochemicals, water treatment, shipbuilding, and heavy machinery manufacturing. Their compact design minimizes installation space requirements, making them easy to deploy in limited spaces, while their high flow rate can meet the fluid transfer needs of large-scale production or processing.
[0003] However, existing technologies still have the following problems: Existing gear pumps still suffer from limitations in achieving high flow rates within compact spaces, as well as insufficient efficiency and reliability. In current technology, gear pumps are often difficult to install in limited spaces due to their complex structure and large size. Their flow rate is also limited, failing to meet the high-efficiency delivery requirements of large-scale production or processing. Furthermore, existing gear pumps are prone to fluid leakage and gear wear during operation, leading to low efficiency and reduced reliability.
[0004] To address the aforementioned problems, the inventors proposed a compact, high-flow gear pump. Summary of the Invention

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Example: Figure 1-3 As shown, this utility model provides a compact, high-flow gear pump, including a mounting base 1. Two symmetrically distributed fixing mechanisms 3 are fixedly mounted on the lower surface of the mounting base 1. A pump body mechanism 2 is fixedly mounted on the upper surface of the mounting base 1. The pump body mechanism 2 includes a cylinder 20, the outer side of which is fixedly connected to the mounting base 1. Two connection ports 27 are opened on the outer side of the cylinder 20. A front end cover 28 and a rear end cover 23 are fixedly mounted on both sides of the cylinder 20, respectively. Two gear cores 21 are rotatably mounted on one side of the front end cover 28 and the rear end cover 23. The gear cores 21 slide against the inner side of the cylinder 20. A connecting base 22 is fixedly mounted on one side of one of the gear cores 21. A drive source connecting shaft 24 is fixedly mounted on one side of the connecting base 22. One end of the drive source connecting shaft 24 passes through one side of the rear end cover 23. When using the pump body mechanism 2, first ensure that the cylinder 20 is securely connected to the mounting base 1. Fluid enters and exits through the two connection ports 27 on the outer side of the cylinder 20. The front cover 28 and the rear cover 23 are fixed to both sides of the cylinder body 20, respectively, and together support two rotating gear cores 21. The gear cores 21 slide and fit inside the cylinder body 20 to ensure smooth fluid delivery. One of the gear cores 21 is connected to the drive source connecting shaft 24 through the connecting base 22. The drive source drives the gear core 21 to rotate through the drive source connecting shaft 24, thereby realizing fluid delivery.
[0016] The fixing mechanism 3 includes a fixing frame 30, the upper surface of which is fixedly connected to the mounting base 1. A rotating frame 32 is fixedly mounted on the lower surface of the fixing frame 30. A rotating rod 31 is fixedly mounted on the inner side of the rotating frame 32. A fixing plate 34 is slidably sleeved on the outer side of the rotating rod 31. A fastening screw 39 is fixedly mounted on the lower surface of the fixing frame 30. A limiting ring 38 is fixedly mounted on the outer side of the fastening screw 39. The lower surface of the limiting ring 38 is in contact with the upper surface of the fixing plate 34. A fastening nut 35 is threaded onto the lower end of the fastening screw 39. The upper surface of the fastening nut 35 is in contact with the lower surface of the fixing plate 34. When installing the fixing mechanism 3, the upper surface of the fixing frame 30 is first fixedly connected to the mounting base 1. The rotating frame 32 is mounted on the lower surface of the fixing frame 30. The fixing plate 34 is slidably sleeved on the outer side of the rotating rod 31 inside the rotating frame 32. By adjusting the position of the fixing plate 34 on the rotating rod 31, different installation requirements can be accommodated. The fastening screw 39 on the lower surface of the fixing bracket 30 passes through the fastening groove 37 on the fixing plate 34 and is fastened by the threaded fastening nut 35. The limiting ring 38 ensures that the fastening screw 39 will not be over-screwed, while the anti-slip pad 36 increases the friction between the fixing bracket 30 and the fixing plate 34, ensuring the stability and reliability of the fixing mechanism 3.
[0017] The sealing gaskets 29 fixed on both sides of the cylinder body 20 effectively enhance the sealing between the cylinder body 20 and the front cover 28 and the rear cover 23, preventing fluid leakage and improving the working efficiency of the pump body mechanism 2. The sealing base 26 fixed on one side of the rear cover 23 and the threaded sealing sleeve 25 further ensure the sealing of the drive source connecting shaft 24 and reduce the risk of leakage caused by the rotation of the drive shaft.
[0018] The anti-slip pads 36 fixedly provided on the lower surface of the fixing bracket 30 and the upper surface of the fixing plate 34 increase the stability and anti-slip properties of the fixing mechanism 3 during installation, thereby improving installation efficiency. The sliding groove 33 on one side of the fixing plate 34 slides and engages with the rotating rod 31, making the fixing plate 34 easier to adjust its position and improving the flexibility of the fixing mechanism 3. The fastening groove 37 on the upper surface of the fixing plate 34 slides and engages with the outer side of the fastening screw 39, ensuring the stability and accuracy of the fastening screw 39 during the fastening process, further improving the reliability and stability of the fixing mechanism 3.
[0019] Working principle: When using pump body mechanism 2, first ensure that cylinder body 20 is securely connected to mounting base 1. Fluid enters and exits through two connection ports 27 on the outside of cylinder body 20. Front cover 28 and rear cover 23 are fixed on both sides of cylinder body 20, supporting two rotating gear cores 21. Gear cores 21 slide and fit inside cylinder body 20, ensuring smooth fluid delivery. One gear core 21 is connected to drive source connecting shaft 24 through connecting base 22. The drive source drives gear core 21 to rotate through drive source connecting shaft 24, thereby realizing fluid delivery. When installing the fixing mechanism 3, first, the upper surface of the fixing frame 30 is fixedly connected to the mounting base 1. The lower surface of the fixing frame 30 is provided with a rotating frame 32, and a fixing plate 34 is slidably sleeved on the outer side of the rotating rod 31 inside the rotating frame 32. By adjusting the position of the fixing plate 34 on the rotating rod 31, different installation requirements can be accommodated. The fastening screw 39 on the lower surface of the fixing frame 30 passes through the fastening groove 37 on the fixing plate 34 and is tightened by the threaded fastening nut 35. The limiting ring 38 ensures that the fastening screw 39 will not be over-screwed, while the anti-slip pad 36 increases the friction between the fixing frame 30 and the fixing plate 34, ensuring the stability and reliability of the fixing mechanism 3.
