HYC leak-free magnetic submerged pump

1. Overview of HYC leak-free magnetic submerged pump

HYC non-leakage magnetic drive submerged pump is a pump type with submerged structure designed for applications where the medium is prevented from leaking out during transportation and requires full closure. The length of the pump varies from 1 to 6 meters. The main part of the pump is all placed in the liquid. The static seal design is adopted, and there is no traditional mechanical seal. The medium can be completely isolated from the outside air, and it is truly leak-free. It is especially suitable for flammable, explosive , toxic, high-risk medium, has the advantages of wide corrosion resistance, high efficiency, safe and reliable shaft connection structure, convenient disassembly, etc., can be pumped without filling liquid, the axial force and radial force generated by the operation of the pump are respectively driven by the rolling bearing and sliding Bearing support, so the operation is quiet and noiseless. It is a high-tech product that integrates environmental protection and energy saving. It has strong corrosion resistance, good wear resistance, high mechanical strength, food grade, reasonable design, compact structure and high performance. Reliable, easy to use and maintain, high efficiency, high efficiency and energy saving.

Second, the advantages of magnetic submerged pump

1.HYC non-leakage magnetic drive submerged pump is a new type of high-efficiency and energy-saving non-leakage submerged centrifugal pump designed in accordance with national standards;
2. The material of pump body, inner rotor, pump cover, impeller, isolation sleeve and pump shaft can be made of 304, 316, 316L, 904, TA2, HC276 and other materials;
3. The pump body and pump cover adopt CFD computer fluid mechanics design hydraulic components for modular design and precision casting, which should be able to withstand the erosion of high-speed and high-pressure liquid, and can withstand the influence of instantaneous thermal shock, with high anti-cavitation ability, accurate size, The flow channel is smooth and clean to ensure the corrosion resistance and pressure resistance of the pump;
4. The impeller also adopts CFD computer fluid mechanics to design hydraulic components for modular design and precision casting, which ensures reliable torque transmission. Its closed structure, optimized design of flow passage, high efficiency and low NPSHR value ensure stable pump flow and head. sex;
5. The isolation sleeve is made of 316L, TA2, HC276 and other materials and the design of the low eddy spacer. The isolation sleeve is in a sinusoidal alternating magnetic field, which induces eddy current on the section perpendicular to the direction of the magnetic field and converts it into heat. The isolation sleeve can be made of non-metallic materials with high resistivity and high strength, which is very effective in reducing eddy current, eliminating all excess heat and reducing energy consumption; it has high rupture resistance and high safety factor, and at the same time the pump The cavity is completely isolated from the outside world, so that the pump chamber is completely sealed, and no leakage is achieved during the conveying process.

6. The moving ring, bushing and sliding bearing are made of crystalline silicon carbide, tungsten carbide and other materials with high wear resistance and temperature resistance, which have high strength, good wear resistance, good willfulness, and strong corrosion resistance, which can effectively ensure the service life of the pump , The rolling bearing adopts imported NSK or SKF grease lubricated maintenance-free bearing;
7. Samarium Cobalt 2:17 is used for the magnet block, its magnetic energy product is 28 Mega Gauss Otes, and the temperature tolerance limit is 350 ℃, which can avoid demagnetization to a large extent, making the theoretical service life of the magnetic material up to 20 years ;
8. The self-balancing structure of the axial force of the pump uses the principle of hydraulics to automatically balance the axial force through the fluid pressure difference. The thrust plate of the rolling bearing only bears the unbalanced axial force at the moment of starting and stopping, and can achieve the shaft at the working point. The force is almost zero, which greatly improves the stability of the whole machine;
9. The magnetic pump adopts a double sliding bearing structure, which runs more smoothly, makes the medium flow smoothly, and has a better lubricating effect of the sliding bearing; the elastic gasket structure in the shaft sleeve and the sliding bearing prolongs the service life of the bearing and reduces the vibration of the pump. At the same time, it avoids the bursting of the sliding bearing caused by high temperature conditions;
10. No leakage, all sealing points are sealed with closed static seals, driven by magnetic couplings, no nitrogen sealing is required, safe, economical and efficient, and the medium leakage is completely solved;

3. Application of magnetic submerged pump

It is widely used in the transportation of volatile, flammable, explosive, toxic, harmful and other high-risk media in the production process of petroleum, chemical, coal, alkali, smelting, rare earth, pesticides, dyes, medicine, scientific research institutions, and national defense industries.
