Kodi Kubereka kwa Magetsi ndi Chiyani?

 

Mphamvu yamagetsi, choyimira chopanda kanthu chomwe chimagwiritsa ntchito mphamvu yamagetsi ndi mphamvu yamagetsi kuti chipangitse kuti shaft ipachikidwe.

 

Mfundo yamabearing amagetsindi yofanana ndi ya sitima ya maglev. Sitima ya maglev ndi chida chamakono chapamwamba choyendera sitima, chomwe chimatha kuyimitsa ndi kutsogolera sitimayo popanda kukhudza njira kudzera mu mphamvu ya maginito, kenako chimagwiritsa ntchito mphamvu ya maginito yopangidwa ndi injini yolunjika kuti ikoke sitimayo kuti iyende, kuchepetsa kukangana.

 

Themphamvu yamagetsiImazindikira chizindikiro cha kupotoka kwa malo a shaft kudzera mu sensa ya malo, imatumiza chizindikiro kwa wolamulira, ndikuwongolera mphamvu ya maginito amagetsi kudzera mu amplifier yamphamvu, kuti ipange kusintha kwa mphamvu yamagetsi kuti spindle ipachikidwe pamalo omwe atchulidwa.

 

2. Ubwino ndi kuipa kwa ma bearing amagetsi

 

Ubwino wamabearing amagetsi:

 

1) Liwiro lalikulu

 

Ma bearing amagetsi amalola rotor kuzungulira pa liwiro lalikulu, liwiro lake limachepetsedwa makamaka ndi mphamvu ya chinthucho, imatha kugwira ntchito motsatira mphamvu ya supercritical, mazana zikwi za ma revolutions pamphindi, ndipo kulondola kwa rotor kuzungulira kwafika pa mulingo wa micron kapena kupitirira apo, komwe ndi liwiro ndi kulondola komwe ma bearing wamba amakina sangafikire.

 

2) Kugwiritsa ntchito mphamvu zochepa

 

Popeza ma bearing amagetsi sakhudzana ndi makina, palibe kukangana kulikonse, ndipo mphamvu yogwiritsira ntchito polimbana ndi kukangana ndi yochepa kwambiri. Pa liwiro la 10,000 r/min, mphamvu yogwiritsira ntchito ndi pafupifupi 15% yokha ya mphamvu ya ma bearing amakina.

 

3) Mtengo wotsika wokonza komanso moyo wautali

 

Popeza ma bearing amagetsi sakhudzana ndi zinthu zoyenda, sawonongeka, sakhudzana ndi zinthu zoyenda, sakumana ndi kutopa kwa makina, ndipo izi zimathetsa vuto la kutayika ndi moyo wa zinthu zoyendera, ndipo kudalirika kwa zinthu zamagetsi ndikokwera kwambiri kuposa kwa zinthu zoyendera zamakina.

 

4) Palibe mafuta ofunikira

 

Ma bearing amagetsi safuna mafuta odzola, zomwe zimachotsa makina odzola ndi zida zina, ndiko kuti, kusunga malo osati kuipitsa chilengedwe ndi makina odzola.

 

5) Ingagwire ntchito mu vacuum ndi kutentha kwakukulu, ndipo kapangidwe kake kakhoza kusiyanasiyana.

 

Zoyipa ndi zovuta za ma electromagnetic bearing:

 

1) Ma electrostatic bearing amafuna mphamvu zambiri zamagetsi, ndipo kugwiritsa ntchito kwake ndi kochepa.

 

2) Chowongolera ndiye chinsinsi, momwe mungapangire chowongolera chokhala ndi kapangidwe kosavuta, magwiridwe antchito abwino komanso kukonza zolakwika mosavuta ndi vuto laukadaulo.

 

3) Momwe mungawunikire momwe zolakwika zogwirira ntchito ndi kupanga zimakhudzira kulamulira kwa maginito ndi nkhani yovuta.

 

4) Momwe mungayang'anire kusakhazikika kwa rotor kumafuna kafukufuku wowonjezera ndi luso logwiritsa ntchito.

 

3. Kugwiritsa ntchito ma electromagnetic bearing

 

Pakadali pano, ma bearing amagetsi akhala akugwiritsidwa ntchito kwambiri m'magawo ambiri, monga sitima zothamanga kwambiri, ma centrifuge othamanga kwambiri, ma hydro turbine generators, ma flywheel a angular momentum a magalimoto amlengalenga, ma flow meter, ma density meter, ma power meter, ma vacuum pumps, ma precision regulators ndi ma gyroscopes.
