I-OPPAIR ingakwazi ukushisa kangakananiisikulufa somoyaukusebenza kwezimoto ngokuvamile?
Izinga lokushisa lemoto libhekisela ezingeni lokumelana nokushisa kwezinto zokushisa ezisetshenziswayo, ezihlukaniswe ngama-grade A, E, B, F, kanye no-H. Ukwenyuka kwezinga lokushisa okuvunyelwe kubhekisela emkhawulweni wokushisa kwemoto uma kuqhathaniswa nokushisa okuzungezile.
Ukwenyuka kwezinga lokushisa kubhekisela enanini lokuthi izinga lokushisa le-stator winding liphakeme kunezinga lokushisa elizungezile ngaphansi kwesimo sokusebenza esilinganisiwe semoto (izinga lokushisa elizungezile lichazwe njengo-35°C noma ngaphansi kuka-40°C, uma inani elithile lingaphawulwanga ku-nameplate, lingu-40°C)
| Isigaba sokushisa sokushisa | A | E | B | F | H |
| Izinga lokushisa eliphezulu elivumelekile (℃) | 105 | 120 | 130 | 155 | 180 |
| Umkhawulo wokunyuka kwezinga lokushisa ojikelezayo (K) | 60 | 75 | 80 | 100 | 125 |
| Izinga lokushisa lokubhekisela kokusebenza (℃) | 80 | 95 | 100 | 120 | 145 |
Emishinini kagesi efana namajeneretha, izinto zokuvikela umswakama yizona ezibuthakathaka kakhulu. Izinto zokuvikela umswakama zithinteka kakhulu ekushiseni okuphezulu kanye nokuguga okusheshayo kanye nomonakalo. Izinto zokuvikela umswakama ezahlukene zinezakhiwo ezahlukene zokumelana nokushisa, kanti imishini kagesi esebenzisa izinto zokuvikela umswakama ezahlukene ingamelana. Amandla okushisa aphezulu ahlukile. Ngakho-ke, imishini kagesi ejwayelekile ibeka izinga lokushisa eliphezulu lomsebenzi wayo.
Ngokwekhono lezinto ezahlukene zokuvikela ukushisa ukumelana nokushisa okuphezulu, kuchazwe amazinga okushisa aphezulu avumelekile ayi-7, ahlelwe ngokuhambisana nokushisa: Y, A, E, B, F, H kanye no-C. Amazinga okushisa avumelekile okusebenza yilawa: Ngaphezu kuka-90, 105, 120, 130, 155, 180 kanye no-180°C. Ngakho-ke, ukuvikela ukushisa kwe-Class B kusho ukuthi izinga lokushisa elingamelani nokushisa lokuvikela ukushisa okusetshenziswa yijeneretha lingu-130°C. Lapho ijeneretha isebenza, umsebenzisi kufanele aqinisekise ukuthi izinto zokuvikela ukushisa zejeneretha azidluli leli zinga lokushisa ukuqinisekisa ukusebenza okuvamile kwejeneretha.
Izinto zokuvala umoya ezinekilasi B lokuvala umoya zenziwe kakhulu nge-mica, i-asbestos, kanye ne-glass filaments ezinamathiselwe noma ezifakwe i-organic glue.

Q: Imoto ingasebenza ngamazinga okushisa angakanani ngokujwayelekile? Yiliphi izinga lokushisa eliphezulu kakhulu injini engalimela?
I-OPPAIRisikulufa somoyaA: Uma izinga lokushisa elilinganisiwe lesembozo semoto lidlula izinga lokushisa elizungezile ngama-degree angaphezu kwama-25, kusho ukuthi izinga lokushisa lemoto lidlule izinga elijwayelekile. Ngokuvamile, izinga lokushisa lemoto kufanele libe ngaphansi kwama-degree angama-20. Ngokuvamile, ikhoyili yemoto yenziwe ngocingo olune-enamel, futhi uma izinga lokushisa lentambo ene-enamel liphakeme kunama-degree angaba ngu-150, ifilimu yopende izowa ngenxa yokushisa okuphezulu, okuholela ekujikelezeni okufushane kwekhoyili. Lapho izinga lokushisa lekhoyili lingaphezu kwama-degrees angu-150, izinga lokushisa lekhoyili yemoto licishe libe ngama-degrees ayi-100, ngakho-ke uma kusekelwe ekushiseni kwekhoyili yayo, izinga lokushisa eliphezulu imoto engalimela lingama-degrees ayi-100.
Q: Izinga lokushisa lemoto kufanele libe ngaphansi kwama-degree Celsius angama-20, okungukuthi, izinga lokushisa lesembozo sokugcina imoto kufanele lidlule izinga lokushisa elizungezile ngaphansi kwama-degree Celsius angama-20, kodwa siyini isizathu esenza imoto ishise ngaphezu kwama-degree Celsius angama-20?
I-OPPAIRisikulufa somoyaA: Uma injini isebenza ngaphansi komthwalo, kuba nokulahleka kwamandla enjinini, okuzogcina sekuwukushisa, okuzokwandisa izinga lokushisa lenjini futhi kudlule izinga lokushisa elizungezile. Inani lokushisa lenjini eliphakeme ngalo kunezinga lokushisa elizungezile libizwa ngokuthi i-ramp-up. Uma izinga lokushisa likhuphuka, injini izokhipha ukushisa endaweni ezungezile; lapho izinga lokushisa liphezulu, kulapho ukushabalalisa ukushisa kushesha khona. Lapho ukushisa okukhishwa yinjini ngesikhathi seyunithi kufana nokushisa okuphelile, izinga lokushisa lenjini ngeke lisakhula, kodwa ligcina izinga lokushisa elizinzile, okungukuthi, esimweni sokulinganisela phakathi kokukhiqizwa kokushisa nokushabalalisa ukushisa.
Q: Kuyini ukwenyuka kwezinga lokushisa okuvunyelwe ngokuchofoza okuvamile? Iyiphi ingxenye yemoto ethinteka kakhulu ukwenyuka kwezinga lokushisa kwemoto? Ichazwa kanjani?
I-OPPAIRisikulufa somoyaA: Uma imoto isebenza ngaphansi komthwalo, kubalulekile ukudlala indima yayo ngangokunokwenzeka. Uma umthwalo umkhulu, kulapho amandla okukhipha angcono khona (uma amandla omshini engacatshangelwa). Kodwa lapho amandla okukhipha emakhulu, lapho ukulahleka kwamandla kukhulu, kulapho izinga lokushisa liphakama khona. Siyazi ukuthi into ebuthakathaka kakhulu emotweni yizinto zokufaka umswakama, njengentambo ene-enamel. Kunomkhawulo wokumelana nokushisa kwezinto zokufaka umswakama. Ngaphakathi kwalo mkhawulo, izakhiwo zomzimba, zamakhemikhali, zemishini, zikagesi nezinye zezinto zokufaka umswakama zizinzile kakhulu, futhi impilo yazo yokusebenza ngokuvamile iyiminyaka engama-20. Uma idlula lo mkhawulo, impilo yezinto zokufaka umswakama ifinyezwa kakhulu, futhi isha ngisho nokusha. Lo mkhawulo wokushisa ubizwa ngokuthi izinga lokushisa elivumelekile lezinto zokufaka umswakama. Izinga lokushisa elivumelekile lezinto zokufaka umswakama liyizinga lokushisa elivumelekile lemoto; impilo yezinto zokufaka umswakama ngokuvamile iyimpilo yemoto.
