Amabhulashi ekhabhoni angaphansi e-Morteng ayizingxenye ezibalulekile kuma-motor ajikelezayo (njengama-generator nama-motor kagesi), asetshenziswa kakhulu ukuqeda ama-shaft currents, ukuvikela ukuphepha kwemishini, nokusiza izinhlelo zokuqapha. Izimo nemisebenzi yazo yilezi ezilandelayo:
I. Imisebenzi Eyinhloko Nemiphumela
- Uma ijeneretha noma imoto isebenza, ukungalingani emkhakheni wamagnetic (njengezikhala zomoya ezingalingani noma umehluko ku-coil impedance) kungabangela i-shaft voltage ku-rotation shaft. Uma i-shaft voltage iphula ifilimu kawoyela we-bearing, ingakha i-shaft current, okuholela ku-electrolysis ye-shaft bearing, ukuwohloka kwe-lubricant, ngisho nokwehluleka kwe-bearing.
- Amabhulashi ekhabhoni aphansi eMorteng afinyeza umgodi we-rotor aye endlini yomshini, ephambukisa imisinga ye-shaft iye phansi futhi ayivimbele ukuthi igeleze ngama-bearings. Isibonelo, amajeneretha amakhulu avame ukufaka amabhulashi ekhabhoni aphansi ekugcineni kwe-turbine, kuyilapho ama-bearings okugcina e-excitation efakwe ama-insulating pads, akha ukucushwa kwe-'excitation end insulation + turbine end grounding' yakudala.
II. Izimo Ezijwayelekile Zokusebenza
-Amajeneretha kagesi ashisayo/amanzi: Amabhulashi ekhabhoni aphansi e-Morteng afakwa ekugcineni kwe-turbine, kanye nama-bearings afudumele ekugcineni kokuvusa, ukuze kuqedwe ukuvuza kwe-magnetic induction shaft voltage. Isibonelo, kumajeneretha kagesi ashisayo, ama-thrust bearings athembele kuphela kufilimu encane kawoyela yokuvikela ukushisa, futhi ukumisa amabhulashi ekhabhoni kungavimbela i-electrolysis yamagobolondo e-bearings.
-Ama-turbine omoya: Asetshenziselwa ama-rotor ejeneretha noma izinhlelo zokuvikela ukukhuphuka, izinto zokwakha zivame ukukhethwa kusuka ku-graphite yensimbi (esekelwe kuthusi/esiliva), enikeza ukuhanjiswa okuphezulu, ukumelana nokuguguleka, kanye nokumelana kwamanje okudlula isikhathi.
-Ama-motor ane-voltage ephezulu/i-variable-frequency: Lawa anengozi ephezulu ye-shaft current. Isibonelo, i-Tonghua Power Generation Company ifake amabhulashi e-grounding carbon ekugcineni kwe-drive ye-primary fan motor, isebenzisa iziphethu ezicindezela njalo ukuze igcine amandla angekho, ngaleyo ndlela ixazulula inkinga yokuthi ama-insulated bearings okuqala awakwazanga ukuvimba ngokuphelele i-shaft current.
-Ukuthuthwa kwesitimela: Ezinjinini zokudonsa zama-locomotive kagesi noma ama-diesel locomotive, amabhulashi e-carbon aphansi aqeda ukunqwabelana kukagesi ongashintshi ngesikhathi sokusebenza, avikele ama-bearings, futhi alondoloze ukuzinza kohlelo lukagesi.
