I-OPPAIR ingenza ubushushu obungakananiisikrufu somoyaukusebenza kwemoto ngokuqhelekileyo?
Umgangatho wobushushu wemoto ubhekisa kwinqanaba lokumelana nobushushu bezinto zobushushu ezisetyenzisiweyo, ezahlulwe zibe ngamanqanaba A, E, B, F, kunye no-H. Ukunyuka kobushushu okuvumelekileyo kubhekisa kumda wobushushu bemoto xa kuthelekiswa nobushushu obungqongileyo.
Ukunyuka kobushushu kubhekisa kwixabiso lokuba ubushushu be-stator winding buphezulu kunobushushu obujikeleze umhlaba phantsi kwemeko yokusebenza elinganisiweyo yemoto (ubushushu obujikeleze umhlaba buchazwe njenge-35°C okanye ngaphantsi kwe-40°C, ukuba ixabiso elithile aliphawulwanga kwi-nameplate, yi-40°C)
| Udidi lobushushu bokugquma | A | E | B | F | H |
| Ubushushu obuphezulu obuvumelekileyo (℃) | 105 | 120 | 130 | 155 | 180 |
| Umda wokunyuka kobushushu obujikelezayo (K) | 60 | 75 | 80 | 100 | 125 |
| Ubushushu bokubhekisa ekusebenzeni (℃) | 80 | 95 | 100 | 120 | 145 |
Kwizixhobo zombane ezifana neejenereyitha, izinto zokukhusela ubushushu zezona zibuthathaka kakhulu. Izinto zokukhusela ubushushu zichaphazeleka kakhulu kubushushu obuphezulu kunye nokwaluphala ngokukhawuleza kunye nomonakalo. Izinto zokukhusela ezahlukeneyo zineempawu ezahlukeneyo zokumelana nobushushu, kwaye izixhobo zombane ezisebenzisa izinto zokukhusela ezahlukeneyo zinokumelana. Amandla obushushu obuphezulu ahlukile. Ke ngoko, izixhobo zombane ngokubanzi zichaza ubushushu obuphezulu bomsebenzi wazo.
Ngokwesakhono sezixhobo ezahlukeneyo zokukhusela ubushushu ukumelana nobushushu obuphezulu, kuchazwe amaqondo obushushu aphezulu asi-7 avumelekileyo, acwangciswe ngokuhambelana nobushushu: Y, A, E, B, F, H kunye no-C. Amaqondo obushushu avumelekileyo okusebenza ngawo ngala: Ngaphezulu kwe-90, 105, 120, 130, 155, 180 kunye ne-180°C. Ke ngoko, ukhuseleko lweKlasi B luthetha ukuba ubushushu obungamelani nobushushu bokhuseleko olusetyenziswa yijenereyitha yi-130°C. Xa ijenereyitha isebenza, umsebenzisi kufuneka aqinisekise ukuba izixhobo zokukhusela ubushushu zejenereyitha azidluli kolu bushushu ukuqinisekisa ukusebenza okuqhelekileyo kwejenereyitha.
Izinto zokukhusela ezikwiklasi B zokukhusela zenziwe nge-mica, i-asbestos, kunye nee-filaments zeglasi ezincamathiselwe okanye ezifakwe iglue yendalo.
Isikrufu somoya se-OPPAIR
Q: Imoto ingasebenza kubushushu obungakanani ngokuqhelekileyo? Lingakanani ubushushu obuphezulu injini enokumelana nabo?
I-OPPAIRisikrufu somoyaA: Ukuba ubushushu obulinganisiweyo besigqubuthelo semoto budlula ubushushu obujikeleze umhlaba ngaphezu kwama-25 degrees, oko kubonisa ukuba ukunyuka kobushushu bemoto kudlule umlinganiselo oqhelekileyo. Ngokubanzi, ukunyuka kobushushu bemoto kufuneka kube ngaphantsi kwama-20 degrees. Ngokubanzi, ikhoyili yemoto yenziwe ngocingo olune-enamel, kwaye xa ubushushu bocingo olune-enamel buphezulu kune-150 degrees, ifilimu yokupenda iya kuwa ngenxa yobushushu obuphezulu, nto leyo ebangela ukujikeleza okufutshane kwekhoyili. Xa ubushushu bekhoyili bungaphezulu kwama-150 degrees, ubushushu bekhoyili yemoto bumalunga nama-100 degrees, ngoko ke ukuba isekelwe kubushushu bayo bekhoyili, ubushushu obuphezulu imoto enokumelana nabo bungama-100 degrees.
Q: Ubushushu bemoto kufuneka bube ngaphantsi kwama-degrees Celsius angama-20, oko kukuthi, ubushushu besiciko semoto kufuneka budlule ubushushu obuphakathi ngaphantsi kwama-degrees Celsius angama-20, kodwa yintoni isizathu sokuba imoto ifudumale ngaphezu kwama-degrees Celsius angama-20?
I-OPPAIRisikrufu somoyaA: Xa i-motor isebenza phantsi komthwalo, kukho ukulahleka kwamandla kwi-motor, okuya kuthi ekugqibeleni kube ngamandla obushushu, okuya kunyusa ubushushu be-motor kwaye kudlule ubushushu obujikeleze i-ambient. Ixabiso apho ubushushu be-motor buphezulu kunobushushu obujikeleze i-ambient libizwa ngokuba yi-ramp-up. Nje ukuba ubushushu bunyuke, i-motor iya kukhupha ubushushu kwindawo engqongileyo; okukhona ubushushu buphezulu, kokukhona ubushushu busasazeka ngokukhawuleza. Xa ubushushu obukhutshwa yi-motor ngexesha leyunithi bulingana nobushushu obuchithekileyo, ubushushu be-motor abusayi kuphinda bunyuke, kodwa bugcina ubushushu obuzinzileyo, oko kukuthi, kwimeko yokulinganisela phakathi kokuveliswa kobushushu kunye nokuchithwa kobushushu.
Q: Yeyiphi inqanaba lokunyuka kwamaqondo obushushu elivumelekileyo xa kuqatshelwa ngokubanzi? Yeyiphi inxalenye yemoto echaphazeleka kakhulu kukunyuka kwamaqondo obushushu emoto? Ichazwa njani?
I-OPPAIRisikrufu somoyaA: Xa imoto isebenza phantsi komthwalo, kuyimfuneko ukudlala indima yayo kangangoko kunokwenzeka. Okukhona umthwalo umkhulu, kokukhona amandla okukhupha (ukuba amandla oomatshini awaqwalaselwanga). Kodwa okukhona amandla okukhupha emkhulu, kokukhona ukulahleka kwamandla kukhulu, kokukhona ubushushu buphezulu. Siyazi ukuba into ebuthathaka kakhulu kwimoto zizinto zokukhusela, ezifana nocingo olufakwe enamel. Kukho umda wokumelana nobushushu bezinto zokukhusela. Ngaphakathi kwalo mda, iipropati zomzimba, zekhemikhali, zoomatshini, zombane kunye nezinye izinto zokukhusela zizinzile kakhulu, kwaye ubomi bazo bokusebenza ngokubanzi bumalunga neminyaka engama-20. Ukudlula lo mda, ubomi bezinto zokukhusela bufutshane kakhulu, kwaye bude butshise. Lo mda wobushushu ubizwa ngokuba bubushushu obuvumelekileyo bezinto zokukhusela. Ubushushu obuvumelekileyo bezinto zokukhusela bubushushu obuvumelekileyo bemoto; ubomi bezinto zokukhusela ngokubanzi bubomi bemoto.
