description The invention relates to the technical field of mechanical engineering sealing and is suitable for sealing a high-linear-speed rotating shaft. The novel high-speed magnetic liquid sealing device comprises a shell, a high-speed rotating shaft I, a planet carrier I, a key I, a low-speed rotating shaft, a left bearing, a left spacer bush, a sealing ring I, a pole shoe I, an annular permanent magnet, a sealing ring II, a pole shoe II, a right spacer bush, a right bearing, an end cover, a planet carrier II, a key II, a high-speed rotating shaft II, a left planet wheel I, a left planet wheel II, a left planet wheel III and a right planet wheel I, and a right planet wheel II and a right planet wheel III. The input high-speed rotating shaft is decelerated by utilizing the planetary gear mechanism, so that the linear speed of the shaft at the sealing part is reduced, and the problems that the friction heating of the magnetic liquid is caused by high linear speed, the pressure resistance is reduced and even the sealing
