Abstract
A high pressure sealing magnetic transmission device comprises a first-stage driving rotor connected with a power source, a first-stage seal isolation cover and a first-stage driven rotor. A second driving rotor, a second-stage seal isolation cover and a second-stage driven rotor are arranged at the power output end of the first-stage driven rotor, and a pressure-bearing seal cavity is arranged between the first-stage seal isolation cover and the second-stage seal isolation cover. During work, after the pressure-bearing seal cavity is pressurized to be with the pressure half of the working pressure, a container requiring the working pressure is pressurized according to a required value. The high pressure sealing magnetic transmission device can increase designed pressure by one time and even more, the isolation covers bear half of the working pressure and even less, and the problem that engineering technicians cannot apply a sealing magnetic transmission device to a high pressure working condition for a long time is solved.
Description
Technical field
The utility model belongs to sealed magnetic transmission device, more particularly, is high pressure sealing magnetic drive.
Background technique
Sealed magnetic transmission device is the new technique equipment of sealing of realizing in another solution transmission process after packing seal, mechanical seal, with the essential distinction of transmission seal device be in the past that sealed magnetic transmission device has been realized zero leakage, under constant voltage, inflammable and explosive, poisonous and harmful and with serious pollution medium operating mode, be widely adopted keeping.
The working principle of sealed magnetic transmission device is the power rotor that connects power source through the driven rotor of the separation sleeve sealing and opposite side outputting power by magnetic field interaction effect transferring power, and separation sleeve has guaranteed seal isolation effect, said magnetic field interaction effect comprises magnetic coupling interaction and magnetic induction effect and magnetic pull effect here.Magnetic coupling interaction refers to that power rotor and driven rotor magnetic field interaction effect derive from installation and be arranged in the permanent-magnet materials on power rotor and driven rotor, and corresponding patent has (magnetic coupling transmission stirring type bioreactor 02278374.1); Magnetic induction effect refers to that in power rotor or driven rotor, having a side at least is conductor structure, and the magnetic field interaction effect between them realizes by magnetic induction, and corresponding patent has (Induction Type Asynchronous High-temperature Magnetic Force Coupling Driver ZL200420025111.X); Magnetic pull effect refers to that in power rotor or driven rotor, having a side at least is soft magnetism structure, magnetic field interaction effect between them realizes the magnetic pull effect of soft magnetism by magnetic field, and corresponding patent has (a kind of thermostable magnetic transmission apparatus ZL200510041415.4).
It is exactly when sealing load is higher that magnetic seal transmission device has individual drawback, due to requirement of strength, separation sleeve is made very thickly, the interactive power rotor in magnetic field and driven rotor clearance distance are very large in this case, so that magnetic field interaction effect is very faint, even can not meet usage requirement, to this, designer is helpless, thinks long and hard solution.
Summary of the invention
The utility model provides high pressure sealing magnetic drive, meets effective use of magnetic drive under elevated pressures.
It is as follows that the utility model solves the problems of the technologies described above adopted technological scheme:
A kind of high pressure sealing magnetic drive is provided, comprise the one-level power rotor that connects power source, the primary seal separation sleeve sealing, with one-level power rotor magnetic field interaction effect and be positioned at the one-level driven rotor of primary seal separation sleeve opposite side, the fixed rotor flange of one-level driven rotor bearing and this bearing of assembling, at one-level driven rotor outputting power end, secondary power rotor is installed, secondary power rotor is again through the secondary seal separation sleeve sealing and the secondary driven rotor magnetic field interaction effect transferring power of opposite side, secondary driven rotor is exported rotating power by secondary driven rotor bearing.Between primary seal separation sleeve and secondary seal separation sleeve, peripheral installation configured pressure-bearing cover, and they have formed pressure bearing and seal chamber jointly.This high pressure sealing magnetic drive is when work, first the pressure bearing and seal chamber between primary seal separation sleeve and secondary seal separation sleeve is pressurized to 1/2nd of working pressure, and then to requiring the container of working pressure to be pressurized to required value, the actual pressure-bearing value of each seal isolation cover only has half of working pressure like this, visible this have in the middle of secondary magnetic drive have a pressure bearing and seal chamber can make design pressure double, above-mentioned power rotor at different levels and driven rotors at different levels magnetic field interaction effect comprise magnetic coupling interaction and magnetic induction effect and magnetic pull effect.
By that analogy, same principle, if sealed magnetic transmission device is designed to have three grades of magnetic drives, there are two pressure bearing and seal chambeies centre, can make so design pressure bring up to original 3 times, as long as correct pressurising order and the force value of arranging, guarantees that the pressure reduction that each separation sleeve bears is no more than 1/3rd of working pressure when work.
The beneficial effects of the utility model are that sealed magnetic transmission device still can use, and meets need of production in the higher situation of pressure, solved perplex for a long time engineers and technicians cannot be by sealed magnetic transmission device the difficult problem for high pressure operating mode.
