Chii chinonzi Electromagnetic Bearing?

 

Kutakura kwemagetsi, bearing isina chinhu inoshandisa simba remagetsi uye simba remagineti kuita kuti shaft irembedzwe.

 

Nheyo yemabheyaringi emagetsiyakafanana neyechitima cheMaglev. Chitima cheMaglev chishandiso chemazuva ano chekufambisa njanji chemhando yepamusoro, chinoita kuti chitima chisabatike uye chitungamirirwe pakati pechitima nenjanji kuburikidza nesimba remagetsi, uye chinoshandisa simba remagetsi rinogadzirwa nemota yakatsetseka kudhonza chitima kuti chimhanye, zvichideredza kukweshana.

 

Iyobheyaringi remagetsiInoona chiratidzo chekutsauka kwenzvimbo yeshaft kuburikidza ne sensor yenzvimbo, inotumira chiratidzo kune controller, uye inodzora magetsi emagetsi kuburikidza ne amplifier yesimba, kuitira kuti igadzire shanduko musimba remagetsi kuti spindle irembedzwe munzvimbo yakatarwa.

 

2. Zvakanakira nezvakaipa zvemabheyaringi emagetsi

 

Zvakanakira zvemabheyaringi emagetsi:

 

1) Kumhanya kwakanyanya

 

Mabheyaringi emagetsi anobvumira rotor kutenderera nekumhanya kwakanyanya, kumhanya kwayo kunonyanya kuganhurirwa nesimba rechinhu chacho, inogona kushanda pasi pesimba guru, mazana ezviuru zvemarevolution paminiti, uye kururama kwekutenderera kwerotor kwasvika padanho re micron kana kutopfuura, inova kumhanya uye kururama uko mabheyaringi akajairwa anogona kure nekusvika.

 

2) Kushandiswa kwesimba kwakaderera

 

Sezvo mabheya emagetsi asina kubatana kwemagetsi, hapana kukweshana kunenge kuripo, uye simba rinoshandiswa kukunda kukweshana rakaderera zvikuru. Nekumhanya kwe10,000 r/min, simba rinoshandiswa rinenge 15% chete yesimba remabheya emagetsi.

 

3) Mutengo wakaderera wekugadzirisa uye hupenyu hurefu

 

Nekuti mabheyaringi emagetsi haana kubatana uye haana kupfeka, haana kubatana pakati penzvimbo dzinofamba, haana kukweshana kwemuchina uye kuneta kwekubatana, zvinogadzirisa dambudziko rekurasikirwa nehupenyu hwezvikamu zvemuchina, uye kuvimbika kwezvikamu zvemagetsi kwakanyanya kupfuura kwezvikamu zvemuchina zvechinyakare.

 

4) Hapana mafuta anodiwa

 

Mabheyaringi emagetsi haadi mafuta anozorwa, zvichibvisa sisitimu yekuzorwa nezvimwe zvishandiso, kureva kuti, kuchengetedza nzvimbo uye kusasvibisa nharaunda nesisitimu yekuzorwa.

 

5) Inogona kushanda mu vacuum uye tembiricha yakakura, uye chimiro chacho chinogona kusiyanisa.

 

Zvakashata nematambudziko emabheyaringi emagetsi:

 

1) Mabheyaringi emagetsi anoda simba guru remagetsi, uye mashandisirwo acho akaganhurirwa.

 

2) Chinodzora ndicho chinhu chikuru, magadzirirwo echinodzora chine chimiro chiri nyore, mashandiro akanaka uye kugadzirisa zviri nyore idambudziko rehunyanzvi.

 

3) Maitiro ekuongorora kukanganisa kwekugadzirisa nekugadzira zvikanganiso pakudzora magineti zvakare inyaya yakaoma.

 

4) Maitiro ekudzora kusagadzikana kwerotor anoda tsvakiridzo yakawedzerwa uye ruzivo rwekushandisa.

 

3. Kushandiswa kwemabheyaringi emagetsi

 

Parizvino, mabheyaringi emagetsi anoshandiswa zvakanyanya munzvimbo dzakawanda, dzakadai sezvitima zvinomhanya zvakanyanya, macentrifuge anomhanya zvakanyanya, majenareta ehydro turbine, mavhiri emota dzemuchadenga, maflow meter, madensity meter, mapower meter, mavacuum pump, ma precision regulators uye magyroscopes.
