The right side of the universal pump hub body 10 is fixedly connected with the discharge port 4, and the bottom of the universal pump hub body 10 is fixedly connected with the feed port 8. The feed port 8 is used to introduce the fluid or medium to be processed, thereby starting the working cycle of the pump. The design of the feed port 8 can ensure that the fluid enters the pump without resistance. The bottom inner wall of the feed port 8 is fixedly connected with a sealing assembly. The sealing assembly minimizes leakage when the pump is running, ensuring the pressure and flow performance of the fluid in the pump;
[0023] The sealing assembly includes a lower water seal ring 27. The outside of the lower water seal ring 27 is fixedly connected to the bottom inner wall of the feed port 8. The lower water seal ring 27 is mainly used to prevent fluid from leaking from the bottom of the pump body and maintain the sealing performance and safe operation of the pump system. The top of the lower water seal ring 27 is fixedly connected to a sealing bearing 26. The top of the sealing bearing 26 is fixedly connected to a lower water seal ring 15. The top of the pump body is fixedly connected to a motor bracket 14. The left side of the feed port 8 is fixedly connected to a bracket 9. The internal rotation of the sealing bearing 12 is connected to the pump shaft 12 to ensure that leakage is effectively reduced during the operation of the pump and improve the operating efficiency and life of the pump. The top of the pump shaft 12 is fixedly connected to an impeller 11. The top of the pump shaft 12 is fixedly connected to a backrest wheel 13. The backrest wheel 13 is used to support and fix the pump shaft 12 to ensure its stability and balance during operation, reduce vibration and noise, and extend the service life of the pump.
[0024] Reference Figure 2 and Figure 3The bottom of the upper water seal ring 1 fits with the top of the sealing bearing 2, and the bottom of the sealing bearing 2 fits with the top of the upper water seal ring 2 3, ensuring the correct position of the upper water seal ring 2 3 in the pump body, and effectively preventing the material from leaking from the gap between the sealing bearing 2 and the upper water seal ring 2 3, maintaining the high efficiency performance of the pump, the bottom of the sealing bearing 2 6 fits with the top of the lower water seal ring 2 7, effectively preventing the material from leaking at the bottom of the pump, maintaining the sealing of the pump system, and protecting the internal components from the influence of the external environment, the top of the sealing bearing 2 6 fits with the top of the feed port 8, so that the material can enter the pump smoothly, and also reduces the leakage problem that may occur in the operation of the pump, thereby improving the operating efficiency and reliability of the pump.
[0025] Working principle: The universal pump hub of this embodiment is set on the salt scraper through the bracket 9 and can move up and down relative to the salt scraper. The feed port 8 is connected to the collection bin of the salt scraper through the feed pipe, and the discharge port 4 is connected to the plastic pipe in the crystallization tank. The feed pipe and the discharge pipe both have a certain hardness. An 18.5 kW motor is installed on the motor bracket 14. When the motor is started, the motor will drive the backrest wheel 13 to rotate, and then the backrest wheel 13 will drive the pump shaft 12 to rotate, so that the pump shaft 12 drives the impeller 11 to rotate. The universal pump hub generates suction to draw the salt from the salt scraper through the feed port 8 into the universal pump hub body 10 and discharge it from the discharge port 4 to the plastic pipe. When the salt scraper changes direction, it drives the discharge pipe and the bracket to rotate. At this time, the discharge pipe and the universal pump hub body 10 can remain unchanged.
[0026] By setting the upper water seal ring 1, the upper water seal ring 2 3 and the sealing bearing 1 2, their combination realizes the connection between the pump body and the universal pump hub body 10, and the liquid will not penetrate into the pump body, ensuring that the internal structure and operating parts of the pump will not be corroded or damaged by the liquid, maintaining the original design performance and efficiency of the pump, and extending the service life of the pump. At the same time, the existence of the lower water seal ring 1 5, the lower water seal ring 2 7 and the sealing bearing 2 6 enables the universal pump hub body 10 to effectively rotate relative to the feed pipe and maintain a seal. Since a rotary joint is no longer required, the cost is effectively reduced. The use of water seal rings to ensure sealing and rotation effectively reduces the resistance to rotation and reduces the wear caused by rotation. The universal pump hub body 10 is connected to the pump body through the upper water seal ring 1, the upper water seal ring 2 and the sealing bearing 1. On the one hand, it reduces the impact of the pump body on the universal pump hub body when it is working, and on the other hand, it ensures that the universal pump hub body rotates relative to the pump body.
