The role of the isolation sleeve in the magnetic pump
The isolation sleeve in the magnetic pump plays a vital role in the magnetic pump system, and its specific functions can be summarized as follows:
1. Isolation of magnetic field
The isolation sleeve of the magnetic pump effectively prevents direct contact between the liquid and the external environment by isolating the magnetic field. This electromagnetic isolation protection ensures that the magnetic transmission system inside the pump is not interfered by external factors, and improves the stability and safety of the pump.
2. Protect core components
The isolation sleeve plays a role of buffering and protection in the operation of the magnetic pump, reducing the degree of wear of the internal parts of the pump. This helps to maintain the efficient operation of the magnetic pump and slow down the aging of the equipment.
3. Leak-free design
The isolation sleeve of the magnetic pump is a key component to achieve the leakage-free design of the magnetic pump. It is located in the middle of the inner magnetic motor rotor and the outer magnetic motor rotor. Through reliable sealing performance, it prevents the leakage of high-pressure liquid in the pump body and prevents air from entering the pump body. This design completely solves the "running, bubbling, dripping, and leaking" problems of traditional pumps, and eliminates the safety hazards of flammable, explosive, toxic and harmful media leaking through the pump seal in industries such as oil refining and chemical industry.
4. Reduce eddy current loss
For metal isolation sleeves, materials with high resistivity (such as Hastelloy, titanium alloy, etc.) should be selected to reduce eddy current loss. Eddy current loss is the magnetic eddy current phenomenon generated in conductive materials due to high-speed alternating magnetic fields, which will cause energy loss and temperature rise. The selection of high resistivity materials can effectively reduce eddy current loss and improve the efficiency of magnetic pumps.
5. Corrosion resistance and high temperature resistance
Isolation sleeves are usually made of materials with strong corrosion resistance and high temperature resistance to adapt to various liquid delivery environments. This design not only extends the service life of the magnetic pump, but also reduces maintenance costs.
6. Adapt to different media
The isolation sleeve can immediately touch the conveying medium, whether the conveying medium is clean or contains hard particles, it can effectively protect it. However, when the conveying medium contains hard particles, it may cause damage to the isolation sleeve, so regular maintenance and inspection are required.
