The pump shaft and the inner magnetic rotor are completely enclosed

From coupling Borehole Pumps Manufacturers to synchronous drag, there is no contact and friction. Because engineering ceramics are very brittle and have a small expansion coefficient, the bearing clearance must not be too small to avoid shaft hung accidents. The working principle of the magnetic pump: n pairs of magnets (n is an even number) are assembled on the inner and outer magnetic rotors of the magnetic drive

in a regular arrangement, so that the magnets form a complete coupling magnetic system. The pump shaft changes from a dynamic seal to a closed static seal, which completely avoids medium leakage. To reduce the vortex, only F and D can be considered. There is no need for independent lubrication and cooling water, which reduces energy consumption. Because engineering ceramics have good heat resistance, corrosion resistance and friction resistance, the sliding bearings of magnetic pumps are mostly made of engineering ceramics. When the pump is designed, n and T are given by the working conditions.

Then the magnets move, driving the magnetic rotor to rotate. 3. Advantages of magnetic pump: Compared with centrifugal pumps that use mechanical seals or packing seals, magnetic pumps have the following advantages: 1.. 1. At this time, the permanent magnet on the magnetic actuator will produce eddy loss and magnetic loss under the action of the alternating magnetic field of the active rotor, which will cause the temperature of the permanent magnet to rise and the magnetic actuator to slip and fail.

The pump shaft and the inner magnetic rotor are completely enclosed by the pump body and the isolating sleeve to avoid problems such as 'running, spilling, dripping, and leakage', and eliminate the safety hazards of flammable, explosive, toxic and other harmful media leaking through the pump seal in the refining and chemical industry . 2. 5.
