Kuyini Ukuthwala Nge-Electromagnetic?

 

Ukuthwala kwe-electromagnetic, ibhere elilula elisebenzisa amandla kagesi kanye namandla kazibuthe ukwenza ishaft ibambeke.

 

Isimiso se-amabheringi kagesikufana nesitimela se-maglev. Isitimela se-maglev siyithuluzi lesimanje lezokuthutha isitimela elisezingeni eliphezulu, elikwazi ukuxhumanisa isitimela ngaphandle kokuthinta kanye nesiqondiso phakathi kwesitimela nomzila ngamandla kagesi, bese lisebenzisa amandla kagesi akhiqizwa yinjini eqondile ukudonsa isitimela ukuze sigijime, okunciphisa ukungqubuzana.

 

Iukuthwala kwe-electromagneticithola isignali yokuphambuka kwesikhundla seshaft ngenzwa yesikhundla, ithumela isignali kumlawuli, futhi ilawula ugesi we-electromagnet nge-power amplifier, ukuze idale ushintsho emandleni kagesi ukuze yenze i-spindle imiswe endaweni ecacisiwe.

 

2. Izinzuzo kanye nokungalungi kwama-electromagnetic bearings

 

Izinzuzo zeamabheringi kagesi:

 

1) Isivinini esiphezulu

 

Ama-bearing kagesi avumela i-rotor ukuthi ijikeleze ngesivinini esikhulu, ijubane layo linqunyelwe kakhulu amandla ezinto ezibonakalayo, ingasebenza ngaphansi kokuguquguquka okukhulu, amakhulu ezinkulungwane ngomzuzu, futhi ukunemba kokujikeleza kwe-rotor kufinyelele ezingeni le-micron noma ngaphezulu, okuyijubane nokunemba okungafinyelelwa ama-bearing avamile emishini.

 

2) Ukusetshenziswa kwamandla okuphansi

 

Njengoba ama-electromagnetic bearing engenawo amandla okuxhumana, cishe akukho ukungqubuzana, futhi ukusetshenziswa kwamandla okunqoba ukungqubuzana kuphansi kakhulu. Ngesivinini esingu-10,000 r/min, ukusetshenziswa kwamandla kungama-15% kuphela alawo ama-mechanical bearing.

 

3) Izindleko zokulungisa eziphansi kanye nokuphila isikhathi eside

 

Ngenxa yokuthi ama-bearings kagesi awathinteki futhi awagugi, awathinteki phakathi kwezindawo ezihambayo, awangqubuzani ngomshini kanye nokukhathala kokuthintana, kuxazulula inkinga yokulahlekelwa nokuphila kwezingxenye zomshini, futhi ukuthembeka kwezingxenye zikagesi kuphakeme kakhulu kunokwezingxenye zendabuko zomshini.

 

4) Akukho ukugcoba okudingekayo

 

Ama-bearings kagesi awadingi ukuthambisa, okususa uhlelo lokuthambisa namanye amadivayisi, okungukuthi, ukonga isikhala futhi kungangcolisi imvelo ngohlelo lokuthambisa.

 

5) Ingasebenza ku-vacuum kanye nobubanzi bokushisa obubanzi, futhi isakhiwo singahlukahluka.

 

Okubi kanye nobunzima be-electromagnetic bearings:

 

1) Ama-bearings e-electrostatic adinga amandla amaningi ensimu kagesi, futhi ukusetshenziswa kwawo kulinganiselwe.

 

2) Isilawuli siyisihluthulelo, indlela yokuklama isilawuli esinesakhiwo esilula, ukusebenza kahle kanye nokulungisa amaphutha okulula kuyinselele yobuchwepheshe.

 

3) Indlela yokuhlola umthelela wamaphutha okucubungula nokukhiqiza ekulawuleni kwe-electromagnetic nakho kuyiphuzu elinzima.

 

4) Indlela yokulawula ukungazinzi kwe-rotor idinga ucwaningo olwengeziwe kanye nolwazi lokusebenzisa.

 

3. Ukusetshenziswa kwama-bearings kagesi

 

Njengamanje, ama-electromagnetic bearings asetshenziswe kabanzi emikhakheni eminingi, njengezitimela ezinesivinini esikhulu kakhulu, ama-centrifuge anesivinini esikhulu kakhulu, ama-hydro turbine generator, ama-angular momentum flywheels ezimoto zasemkhathini, amamitha okugeleza, amamitha okuminyana, amamitha kagesi, amaphampu e-vacuum, abalawuli bokunemba kanye nama-gyroscope.
