Description

Technical Field

[0001] This utility model relates to the technical field of magnetic pump isolation sleeves, and in particular to a high-strength magnetic pump isolation sleeve. Background Technology

[0002] In modern industrial production, magnetic pumps are widely used in chemical, pharmaceutical, and food industries due to their advantages such as leak-free operation and strong corrosion resistance. However, traditional high-strength magnetic pump isolation sleeves have many technical bottlenecks in the fluid transportation process, especially the series of problems caused by fluid eddies, which seriously restrict the improvement of magnetic pump performance and industry production efficiency.

[0003] Traditional magnetic pumps have a relatively simple internal structure design for the isolation sleeve, with the inner wall mostly being a smooth plane. This lack of effective guidance for fluid flow means that when fluid enters the isolation sleeve, the lack of a specific flow-guiding structure leads to chaotic flow direction and the formation of eddies. For example, in some magnetic pumps using traditional isolation sleeves, strong eddies are formed at bends and abrupt changes in cross-section due to the rapid changes in velocity and direction. These eddies not only hinder normal fluid flow but also cause significant energy loss. Therefore, these problems need to be addressed. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-4This utility model discloses a high-strength magnetic pump isolation sleeve, comprising an outer sleeve 1 and an inner sleeve 2 fitted inside the outer sleeve 1. The inner sleeve 2 effectively resists fluid erosion and extends the service life of the isolation sleeve. Both the outer sleeve 1 and the inner sleeve 2 have communication openings at their tops. The inner wall of the inner sleeve 2 is provided with anti-vortex guide plates 6 to reduce fluid resistance. The bottom of the inner sleeve 2 is provided with a buffer pad 7, which helps reduce the impact of vibration on other pump components, improving the stability and reliability of the magnetic pump operation. Multiple vents are provided on the buffer pad 7. 9. The exhaust port 9 facilitates the smooth discharge of gas inside the isolation sleeve, optimizes the fluid transport environment, and improves the operating efficiency of the magnetic pump. The bottom of the outer sleeve 1 is screwed with fastening bolts 8, which ensures a tight connection between the isolation sleeve and the pump body, preventing loosening or falling off during pump operation and maintaining the stability of the magnetic pump operation. The bottom of the inner side of the outer sleeve 1 is fixed with multiple reinforcing ribs 11, which significantly improve the strength and stability of the outer sleeve 1, enabling the isolation sleeve to operate reliably under high pressure and high stress conditions and extending its service life.

[0020] In this utility model, the bottom of the outer ring of the inner sleeve 2 is provided with an abutment groove 10, and the top of the outer ring of the outer sleeve 1 is provided with a protrusion 12. The abutment groove 10 and the protrusion 12 are connected. A sealing strip 5 is pasted on the side wall of the outer ring of the inner sleeve 2 and the outer sleeve 1. The protrusion 12 facilitates the improvement of the installation accuracy and stability of the inner and outer sleeves 1, making the overall structure of the isolation sleeve more reliable and the sealing performance better. The anti-vortex guide plate 6 is made of polytetrafluoroethylene and is arranged in a spiral shape. The anti-vortex guide plate 6 can significantly reduce the fluid flow resistance, improve the delivery efficiency of the magnetic pump, and reduce energy consumption. It makes the fluid flow more stable and reduces energy loss and mechanical vibration caused by vortices. The inner sleeve 2 is made of corrosion-resistant material. The inner sleeve 2 is made of corrosive polytetrafluoroethylene. Multiple vent ports 9 are evenly spaced at the bottom of the inner sleeve 2. The outer sleeve 1 is made of specially treated iron-nickel soft magnetic alloy. Multiple vent ports 9 are evenly spaced at the bottom of the outer sleeve 1. The outer sleeve 1 provides high-strength mechanical support for the entire isolation sleeve and can withstand external pressure and mechanical stress. A threaded post 4 is inserted into the connecting port. The threaded post 4 has two limiting nuts 3. One limiting nut 3 abuts against the top surface of the inner sleeve 2 and the other limiting nut 3 abuts against the bottom surface of the outer sleeve 1. The threaded post 4 ensures that the outer sleeve 1 and the inner sleeve 2 are tightly and firmly connected, so that the isolation sleeve can effectively withstand various forces during the operation of the pump and maintain the stability of the magnetic pump operation.

[0021] Working Principle: When using this invention, firstly, when installing the high-strength magnetic pump isolation sleeve, the inner sleeve 2 is fitted into the outer sleeve 1. The abutment groove 10 at the bottom of the outer ring of the inner sleeve 2 precisely aligns with the protrusion 12 at the top of the outer ring of the outer sleeve 1, achieving initial positioning. Subsequently, the sealing strip 5 is pasted onto the side wall of the outer ring of the outer sleeve 1 and the inner sleeve 2 to fill the gap and enhance the sealing. Next, the threaded post 4 is inserted into the communication port at the top of the outer sleeve 1 and the inner sleeve 2. By tightening the two limiting nuts 3, one abutting the top surface of the inner sleeve 2 and the other abutting the bottom surface of the outer sleeve 1, the inner and outer sleeves 1 are firmly fixed. Finally, the isolation sleeve is tightly connected to the magnetic pump body or other components by the fastening bolts 8 at the bottom of the outer sleeve 1, ensuring that the entire isolation sleeve remains stable during pump operation without displacement or loosening. Then, when the magnetic pump starts running, the fluid being pumped enters the interior of the isolation sleeve and directly contacts the inner sleeve 2. Because the inner sleeve 2 is made of corrosion-resistant polytetrafluoroethylene, it can effectively resist the erosion of the fluid. The high-strength magnetic pump isolation sleeve protects the isolation sleeve from corrosion and extends its service life. Simultaneously, the spirally arranged anti-vortex guide vanes 6 on the inner wall of the inner sleeve 2 guide the fluid to flow smoothly along the vane direction, disrupting the formation of fluid vortices and significantly reducing the flow resistance within the isolation sleeve. This allows the fluid to pass through the isolation sleeve efficiently, improving the pump's delivery efficiency. Finally, during fluid delivery, the fluid impacts the bottom of the isolation sleeve, and the pump operation also generates mechanical vibrations. At this time, the buffer pad 7 at the bottom of the inner sleeve 2 acts as a buffer, absorbing the fluid impact and mechanical vibrations, reducing the impact of vibration transmission on the inner sleeve 2 and other pump components, protecting the stability of the isolation sleeve structure and the pump body. The buffer pad 7, along with the vents 9 at the bottom of the outer sleeve 1 and inner sleeve 2, are responsible for venting the gas accumulated inside the isolation sleeve, preventing gas from forming airlocks that could affect fluid delivery and pump performance, ensuring an optimized fluid delivery environment, and enabling the magnetic pump to operate stably and efficiently. This concludes the use of the high-strength magnetic pump isolation sleeve.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
