Circulation Cooling Structure for Magnetic Isolation Sleeve Reduces Heat Accumulation Inside Magnetic Pump Cavity under Long-Term Full-Load Operation

The relative rotation between the inner magnetic rotor and outer magnetic rotor will continuously generate eddy current heat on the isolation sleeve during the operation of magnetic pumps. If heat cannot be discharged in time, local high temperature will accelerate the aging of isolation sleeve materials and weaken the magnetic field strength, resulting in gradual attenuation of pump conveying efficiency in long-term operation.

Yida sets up independent medium circulation cooling flow passages inside the pump body. Part of the conveyed corrosive medium flows around the isolation sleeve along the preset flow channel to continuously take away accumulated operating heat. The passive cooling method relies on the medium itself for heat dissipation without additional cooling auxiliary equipment.

The internal cooling structure effectively controls the operating temperature of core magnetic components within a safe range, slows down the attenuation speed of permanent magnet performance, and significantly prolongs the stable service life of magnetic pumps in 24-hour continuous production lines of global chemical and environmental protection industries.
