[0002] As an important energy and chemical raw material, oil transfer pumps are indispensable key equipment in the processes of oil extraction, transportation, and processing. Their function is to transport oil from the extraction site, storage tank, or pipeline to the processing plant, storage and transportation facilities, or other destinations. The performance of the oil transfer pump directly affects the efficiency, safety, and economy of oil transportation. Gear pumps are one of the commonly used oil transfer pumps because they are suitable for transporting high-viscosity liquids.

[0003] However, current gear pumps have problems of insufficient conveying efficiency and adaptability during oil transportation. Parameters such as the viscosity and flow rate of oil change with factors such as oil type and temperature. The pump body and gear sizes of traditional gear pumps are fixed, making it difficult to adapt to different working conditions, resulting in low conveying efficiency and even problems such as pump body wear and jamming. Currently, some gear pumps can replace the pump body and gears, but their assembly is complex and the maintenance cost is high. The traditional structure lacks auxiliary assembly design, leading to a complex assembly process and easy occurrence of poor docking between the pump body and the drive structure, affecting the safe use of the gear pump.

Detailed implementation manners

[0029] Next, in combination with the accompanying drawings and specific implementation manners, the present invention will be further described. It should be noted that, on the premise of non-conflict, any combination of the following-described embodiments or technical features can form a new embodiment. It should be known that the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1 to 11 , the present invention provides a technical solution: an oil refining transfer pump.

[0031] As Figures 1 - 3 , this transfer pump belongs to a gear pump and is mainly composed of a driving device 2 and a conveying device. The driving device 2 and the conveying device are both installed on the base 1. Among them, the driving device 2 includes an energy-saving motor and a driving shaft cylinder 3. A driving shaft 20 is installed in the driving shaft cylinder 3 through a bearing, and the driving shaft 20 is connected to the motor shaft of the energy-saving motor. The conveying device is a pump body module 4. The pump body module 4 includes a main pump body and a sub-pump body. The main pump body and the sub-pump body have the same structure but different size ratios. Corresponding-sized gear sets 6 are provided in the main pump body and the sub-pump body, which can have different conveying efficiencies, and the sub-pump body can be replaced with a variety of different sizes. At the same time, docking shaft cylinders 5 with the same structure and size are installed on the main pump body and the sub-pump body to ensure that they can all be assembled on the driving device 2. A joint 7 is provided on the pump body module 4 for connecting the inlet pipe and the outlet pipe.

[0032] As Figure 10 、 Figure 11, considering the need to switch and use the pump body module 4, the present invention sets up an assembly frame structure on the base 1, which can assist in positioning and assembling the pump body module 4. The assembly frame structure includes a limit seat 8 installed on the base 1. A sliding seat 9 is slidably installed in the limit seat 8, and the sliding seat 9 is limited by a limit spring 10. Therefore, the sliding seat 9 has a certain ability to move and adjust, making the assembly more flexible. A rotating frame 11 is rotatably installed on the sliding seat 9, and a clamping seat 12 is provided on the rotating frame 11. The fixture structure is detachably installed through the clamping seat 12. The fixture structure includes a bottom buckle 13 and a buckle. Both the bottom buckle 13 and the buckle are semi-circular structures. The buckle is hinged to the bottom buckle 13, and the buckle can be fixed to the bottom buckle 13 by bolts. The docking shaft cylinder 5 can be positioned and fixed therein through the buckling of the bottom buckle 13 and the buckle. During assembly, first rotate the rotating frame 11 to the horizontal state, then fix the pump body module 4 in the fixture structure through the docking shaft cylinder 5, and then rotate the rotating frame 11 to the vertical state, so that the docking shaft cylinder 5 is docked with the driving shaft cylinder 3 together.

[0033] As Figure 11 , the fixture structure and the clamping seat 12 are detachably connected. Therefore, after the fixture structure and the docking shaft cylinder 5 are fixed, the clamping seat 12 can be separated from the fixture structure, so that the pump body module 4 can be used without being affected by the rotating frame 11. Among them, a slotted hole 17 is provided on the clamping seat 12, and a clamping block 15 is fixedly installed on the side of the bottom buckle 13. A limiting member 16 is rotatably installed on the clamping block 15. The limiting member 16 adopts a T-shaped structure. When installing the fixture structure, insert the clamping block 15 into the clamping seat 12. At this time, the limiting member 16 rotates to a state where it can pass through the slotted hole 17. After the clamping block 15 is connected in the clamping seat 12, rotate the limiting member 16, and fix and limit the clamping block 15 through the connection between the limiting member 16 and the back of the clamping seat 12, so as to assemble the fixture structure on the rotating frame 11. Upper fixing members 18 and lower fixing members 19 are respectively provided on the bottom buckle 13 of the fixture structure, and can be fixedly connected to the driving shaft cylinder 3 and the base 1 through screws, so as to indirectly install the docking shaft cylinder 5 on the driving shaft cylinder 3 through the fixture structure. After completion, rotate the limiting member 16 so that it can pass through the slotted hole 17, and then rotate the rotating frame 11 back to the horizontal state for use. At this time, the docking shaft cylinder 5 and the driving shaft cylinder 3 are aligned and assembled.

[0034] As Figure 5 , Figure 6, a hexagonal docking hole 21 is provided on the drive shaft 20 in the drive shaft cylinder 3 for connecting with the axle 24 of the gear set 6. Moreover, a collar 22 is provided on the end face of the drive shaft cylinder 3. A snap ring 32 is provided in the docking shaft cylinder 5. After the snap ring 32 is connected to the collar 22, it can prevent the drive shaft cylinder 3 and the docking shaft cylinder 5 from being misaligned. At the same time, a telescopic shaft 25 is installed in the axle 24 in a limited sliding manner, and an elastic member is connected between the telescopic shaft 25 and the axle 24, which can make the telescopic shaft 25 extend through elasticity. Further, a conical head 26 is connected to the telescopic shaft 25, and a docking head 27 is fixedly connected to the conical head 26. The cross-sectional shape of the docking head 27 is hexagonal and can be inserted into the docking hole 21 to complete the docking of the drive shaft 20 and the axle 24.

[0035] As Figure 7 , Figure 8 , both the docking head 27 and the snap ring 32 adopt an automatic telescopic structure. The docking head 27 is connected to the axle 24 through the telescopic shaft 25, while the snap ring 32 is telescopically connected to the swivel base 31 on the side wall of the docking shaft cylinder 5. At the same time, spring rods 28 are fixedly installed on the inner walls on both sides of the docking shaft cylinder 5, and the ferromagnetic frame 29 is installed in a limited manner through the spring rods 28. Pressure blocks 30 are installed on both sides of the ferromagnetic frame 29, and the pressure blocks 30 are on both sides of the conical head 26. Under normal circumstances, the ferromagnetic frame 29 is in the middle of the docking shaft cylinder 5 under the action of elastic force, and the pressure blocks 30 do not contact the conical head 26. At the same time, both sides of the snap ring 32 are connected to the ferromagnetic frame 29 through a pull rope 33. In the state where the ferromagnetic frame 29 is centered, the snap ring 32 is in a popped state. At the same time, a magnetic seat 34 is fixedly installed on the clamping seat 12 of the present invention. When the docking shaft cylinder 5 is installed in the fixture structure, the magnetic force of the magnetic seat 34 can attract the ferromagnetic frame 29, causing the ferromagnetic frame 29 to shift to one side, generating pressure on the conical head 26 through the pressure blocks 30, making it drive the docking head 27 to retract. Moreover, the ferromagnetic frame 29 can pull back the snap ring 32 through the pull rope 33 to keep it in a retracted state. Therefore, when the docking shaft cylinder 5 and the drive shaft cylinder 3 are docked by rotating the rotating frame 11, both the snap ring 32 and the docking head 27 retract into the docking shaft cylinder 5 and will not cause obstruction. After the docking shaft cylinder 5 is fixed and the rotating frame 11 rotates back, the magnetic seat 34 moves away, the ferromagnetic frame 29 resets, the docking head 27 can extend to connect with the drive shaft 20, and the snap ring 32 can also pop out to dock with the collar 22.

[0036] As Figure 5 , in order to ensure that the docking head 27 can be exactly inserted into the docking hole 21 of the drive shaft 20 when it pops out, it is necessary to manually rotate the docking head 27 to a corresponding angle during assembly. Considering that it is not easy to adjust when the drive shaft 20 retracts into the drive shaft cylinder 3, a ferromagnetic block 23 is fixedly installed on one side of the drive shaft 20. When the rotating frame 11 is in a vertical state, the magnetic seat 34 can also attract the ferromagnetic block 23, making the drive shaft 20 automatically rotate to a corresponding state.

[0037] An oil refining transportation system, which mainly consists of an oil pump module, a pipeline network, a control system and auxiliary equipment, can adapt to the oil transportation requirements with different viscosities, flow rates and pressures, and is widely used in the processes of oil extraction, transportation and refining.

[0044] Control unit: It automatically adjusts the operating parameters of the oil pump according to the sensor data, such as the motor speed. At the same time, it can give a reminder for replacing the pump body module 4 to optimize the transportation efficiency.

[0045] Human-machine interface: It provides an operation interface to facilitate users to monitor the system status and perform manual control.

[0046] The auxiliary equipment includes: Filter: It is installed at the front end of the inlet pipeline to filter out solid particles in the oil and protect the gear set 6 of the oil pump from wear.

[0047] Cooling system: It is used to cool the oil pump and the motor to prevent the equipment from overheating.

[0048] Safety valve: It automatically relieves pressure when the pipeline pressure is too high to ensure the safety of the system.

[0049] The working process of the system is as follows: Startup stage: Select a suitable pump body module 4 (main pump body or sub-pump body) according to the transportation requirements.

[0050] Dock the pump body module 4 with the drive device 2 through the assembly rack to ensure the precise connection between the docking shaft cylinder 5 and the drive shaft cylinder 3. Start the energy-saving motor, and the drive gear set 6 begins to operate.

[0051] Transportation stage: Oil enters the pump body module 4 through the inlet pipe and is transported to the outlet pipe under the action of the gear set 6. The control system monitors parameters such as flow rate and pressure in real time, and automatically adjusts the motor speed or switches the pump body module 4 to adapt to different transportation requirements.

[0052] Maintenance stage: When it is necessary to replace the pump body module 4 or perform maintenance, quickly disassemble and install the pump body module 4 through the assembly rack. Utilize the flexibility of the fixture structure and the rotating rack 11 to simplify the assembly process and reduce the downtime.

[0053] The modular design of the transportation system enables the system to quickly adapt to the transportation requirements of different viscosities, flow rates, and pressures, improving the transportation efficiency. The oil refining and transportation system of the present invention solves the problems of insufficient adaptability, difficult maintenance, and low efficiency in the traditional oil transportation system through the combination of modular oil pumps, intelligent control, and an efficient pipeline network.
