The impeller 9, I-shaped rotating rod 8, hexagonal locking block 7, and transmission gear 5 extend into the interior of the transmission gear 5. The intake impeller 9 connects and fixes the transmission gear 5 and I-shaped rotating rod 8 via a connecting screw 10. A transmission shaft 11 is rotatably connected to the surface of the upper housing 2, and a drive gear 12 is fixedly connected to the bottom end of the transmission shaft 11. The surface of the drive gear 12 meshes with the surface of the transmission gear 5.

In addition, the connecting screw 10 connects and fixes the suction impeller 9 to the I-shaped rotating rod 8 and the transmission gear 5, so as to form a... As a whole, the intake impeller 9 rotates along with the rotation of the I-shaped rotating rod 8 and the transmission gear 5, thereby generating suction and pressurizing the internal components to complete the normal operation of the turbine booster pump. The whole is connected to the lower housing 3 to the L-shaped support rod 4, which rotates to support the transmission gear 5. Then, the transmission gear 5 and the I-shaped rotating rod 8 are connected and fixed by the connecting screw 10, so that the whole is not directly connected and fixed to the upper housing 2. When disassembling, you only need to loosen the connecting screw 10, which can be quickly disassembled and assembled, reducing the difficulty of disassembly and thus improving the efficiency of disassembly and maintenance.

[0028] Furthermore, such as Figure 1 and Figure 3As shown, a motor cylinder 13 is fixedly connected to the middle of the top of the upper housing 2. An electric motor 14 is fixedly connected inside the motor cylinder 13. The output shaft of the electric motor 14 is fixedly connected to the top end of a transmission shaft 11 via a coupling.

The support base 1 supports and fixes the dampers 15. The dampers 15, together with the buffer plate 16, abut against the surface of the lower housing 3, providing cushioning and shock absorption for the lower housing 3, further ensuring operational stability.

A sealing top plate 20 is rotatably connected to the surface of the drive shaft 11 and the top of the drive gear 12. The bottom of the sealing top plate 20 is snapped into the top of the square frame 19. A sealing frame strip 21 is snapped into the connection between the inner walls of the upper housing 2 and the lower housing 3. A feed pipe 22 is connected to one side of the top of the upper housing 2, and a discharge pipe 23 is connected to the side of the top of the upper housing 2 away from the feed pipe 22. During operation, the lower housing 3 supports and fixes the support pin 17, which in turn supports the sealing base plate 18. Simultaneously, the L-shaped strut 4 fixes the sealing base plate 18, and the square frame 19 can be locked onto the top of the sealing base plate 18. The I-shaped rotating rod 8 can rotate on one side of the square frame 19. Furthermore, the sealing top plate 20 is mounted on the transmission shaft 11 at the top of the drive gear 12. The transmission shaft 11 can also rotate on the sealing top plate 20. During installation, the sealing top plate 20 can be locked onto the square frame 19, thus completing the assembly of the sealing base plate 18, the square frame 19, and the sealing top plate 20. This provides internal sealing protection. The entire assembly, through the sealing base plate 18, the square frame 19, and the sealing top plate 20, can be disassembled, while simultaneously providing sealing protection for the internal transmission gear 5 and drive gear 12, ensuring the service life of the internal components. The sealing frame strip 21 seals the connection between the upper housing 2 and the lower housing 3; the feed pipe 22 is used for feeding, and the discharge pipe 23 is used for discharging.

[0030] Furthermore, such as Figure 2 and Figure 4 As shown, the upper housing 2 is threaded with mounting bolts 24 on its outer side, and the upper housing 2 is fixedly connected to the lower housing 3 by the mounting bolts 24. An arc-shaped placement bracket 25 is fixedly connected to the top of the support base 1, and internal bolts 26 are threaded on both sides of the top of the lower housing 3, and the lower housing 3 is fixedly connected to the arc-shaped placement bracket 25 by the internal bolts 26. During operation, the upper housing 2 and lower housing 3 are connected together using the mounting bolts 24, the support base 1 supports and fixes the arc-shaped placement bracket 25, and the lower housing 3 is fixed to the arc-shaped placement bracket 25 by the internal bolts 26. This allows for the disassembly of both the upper housing 2 and the lower housing 3, as well as the lower housing 3 and the arc-shaped placement bracket 25, making disassembly and maintenance more thorough and further improving its adaptability.

[0031] Working principle: First, the upper housing 2 and the lower housing 3 form a complete outer casing of the turbo booster pump. The bottom of the inner wall of the lower housing 3 is supported by an L-shaped strut 4. The transmission gear 5 can rotate on the L-shaped strut 4, which provides rotational support for the transmission gear 5. The transmission shaft 11 can rotate on the surface of the upper housing 2. The rotation of the transmission shaft 11 drives the drive gear 12 to rotate. The drive gear 12 meshes with the transmission gear 5, allowing the drive gear 12 to rotate and drive the transmission gear 5 to rotate. A hexagonal groove 6 is formed on the surface of the transmission gear 5. An I-shaped rotating rod 8, in conjunction with a hexagonal locking block 7, engages with the hexagonal groove 6, causing the transmission gear 5 to rotate and drive the I-shaped rotating rod 8 to begin rotating. Additionally, a connection... The lead screw 10 connects and fixes the suction impeller 9 to the I-shaped rotating rod 8 and the transmission gear 5, forming a whole. This causes the suction impeller 9 to rotate along with the rotation of the I-shaped rotating rod 8 and the transmission gear 5, thereby generating suction and pressurizing the internal components to complete the normal operation of the turbine booster pump. The whole is connected to the lower housing 3 to connect the L-shaped support rod 4, which rotates to support the transmission gear 5. Then, the connecting lead screw 10 connects and fixes the transmission gear 5 and the I-shaped rotating rod 8, so that the whole is not directly connected and fixed to the upper housing 2. Disassembly only requires loosening the connecting lead screw 10, which can be quickly disassembled and assembled, reducing the difficulty of disassembly and improving the efficiency of disassembly and maintenance. Next, the upper housing 2 supports and fixes the motor cylinder 13, and the motor cylinder 13 supports and fixes the motor 14. After the motor 14 starts working, it drives the transmission shaft 11 to start rotating through the output shaft, thereby providing power for the overall rotation operation. Meanwhile, the support base 1 supports and fixes the damper 15. The damper 15, together with the buffer plate 16, abuts against the surface of the lower housing 3, which can buffer and reduce shock for the lower housing 3, further ensuring the stability of the operation. In addition, the lower housing 3 supports and fixes the support pin 17, which in turn supports the sealing base plate 18. At the same time, the L-shaped strut 4 fixes the sealing base plate 18, and the square frame 19 can be locked onto the top of the sealing base plate 18. The I-shaped rotating rod 8 can rotate on one side of the square frame 19. Furthermore, the sealing top plate 20 is set on the transmission shaft 11 at the top of the drive gear 12, and the transmission shaft 11 can also rotate on the sealing top plate 20. During installation, the sealing top plate 20 can be locked onto the square frame 19, thereby completing the assembly of the sealing base plate 18, the square frame 19, and the sealing top plate 20, which can provide internal sealing protection. The entire assembly can be disassembled by setting the sealing base plate 18, the square frame 19, and the sealing top plate 20, while also providing internal sealing protection for the transmission gear 5 and the drive gear 12, ensuring the service life of the internal components. The sealing frame strip 21 seals the connection between the upper housing 2 and the lower housing 3; the feed pipe 22 is used for feeding, and the discharge pipe 23 is used for discharging.Finally, the upper housing 2 and the lower housing 3 are connected together using mounting bolts 24. The support base 1 supports and fixes the arc-shaped placement frame 25. The lower housing 3 is fixed to the arc-shaped placement frame 25 by the built-in bolts 26. The whole structure allows the upper housing 2 and the lower housing 3 to be disassembled, and the lower housing 3 and the arc-shaped placement frame 25 can also be disassembled, making disassembly and maintenance more thorough and further improving the adaptability of use.
