9. a kind of cooling seal system for energy storage device of magnetic suspension flywheel according to claim 1, which is characterized in that
The specifically used operating procedure of the cooling seal system are as follows:
Step 1: the pedestal (1) of energy storage device of magnetic suspension flywheel is fixed on workbench, then by external circulating pump
The water inlet pipe (15) and outlet pipe (16) of input/output port and energy storage device of magnetic suspension flywheel shell (8) side wall are attached,
The conducting wire of energy storage device of magnetic suspension flywheel and external power supply unit are attached；
Step 2: when energy storage, external power supply unit by power transmission to magnetic levitation energy storage device housing (8) it is internal it is electronic/
Generator unit stator (7) is rotated by the field drives dynamoelectric machine rotor (17) that dynamoelectric machine stator (7) generate, by
It is attached with accumulated energy flywheel (19) by a transmission shaft (12) in dynamoelectric machine rotor (17), thus by rapidly revolving
The dynamoelectric machine rotor (17) turned drives accumulated energy flywheel (19) rotation, realizes power storage into kinetic energy；
Step 3: when releasing energy, the accumulated energy flywheel (19) rapidly rotated drives dynamoelectric machine rotor by transmission shaft (12)
(17) high speed rotation, dynamoelectric machine rotor (17) can do cutting magnetic induction line movement in dynamoelectric machine stator (7), thus will
The kinetic energy of accumulated energy flywheel (19) is converted into electric energy；
Step 4: during dynamoelectric machine stator (7) generate electricity and drive dynamoelectric machine rotor (17), inside
Coil can generate heat, coolant liquid is input to the internal cooling of support frame (18) by water inlet pipe (15) by circulating pump external at this time
Water pipe (34) and upper heat sink (14) are internal, coolant liquid are finally transmitted back to circulating pump by outlet pipe (16), thus to electricity
The heat that dynamic/generator unit stator (7) generates radiates, simultaneously because dynamoelectric machine stator (7) and upper heat sink (14) with
And there are the temperature difference between support frame (18), by the first thermoelectric generation film (28) and the second thermoelectric generation film (30) by the temperature difference
It is converted into electric energy；
Step 5: accumulated energy flywheel (19) is during high speed rotation, the impurity and accumulated energy flywheel (19) of surface attachment
The phenomenon that point collapsing can occur under the action of the centrifugal force in own material, at this time by Electrostatic Absorption net (6) to will be under vacuum environment
The impurity of suspension is adsorbed, and when cleaning is needed, filter screen is covered at air valve (10) suction nozzle, opens air valve (10) balance
Clean cover (21) are then dismantled, shell (8) are beaten by the small size high frequency of rubber hammer later, so that electrostatic be inhaled by air pressure inside
The dust adhered on attached net (6) shakes off, and is then collected at exhaust hole (25), later dismantles adsorption filter screen (24), uses
Family can clean magnetic levitation energy storage device, be assembled in a reverse order later, then be taken out by air valve (10)
Vacuum.
