I-blade yinxalenye ephambili ye-injini yomphunga kwaye yenye yezona ndawo zibuthathaka kwaye zibalulekileyo.Ithwala iziphumo ezidityanisiweyo zobushushu obuphezulu, uxinzelelo oluphezulu, amandla amakhulu aphakathi, amandla omphunga, amandla anika umdla amnandi, umhlwa kunye nokungcangcazela kunye nokhukuliseko lwamathontsi amanzi kwindawo emanzi phantsi kweemeko ezinzima kakhulu.Ukusebenza kwayo kwe-aerodynamic, i-geometry yokucubungula, ubuninzi bomhlaba, ukukhutshwa kofakelo, iimeko zokusebenza, ukulinganisa kunye nezinye izinto ezichaphazela ukusebenza kakuhle kunye nokukhutshwa kwe-turbine;Uyilo lwayo lwesakhiwo, ukuqina kokungcangcazela kunye nemodi yokusebenza kunempembelelo eqinisekileyo kukhuseleko kunye nokuthembeka kweyunithi.Ke ngoko, awona maqela emveliso adumileyo kwihlabathi enze iinzame ezingapheliyo zokusebenzisa ezona mpumelelo ziphambili zenzululwazi kunye netekhnoloji kuphuhliso lwamagqabi amatsha, kwaye rhoqo sazisa iiblade ezintsha ngokusebenza okuphezulu ukusuka kwisizukulwana ukuya kwesinye isizukulwana ukukhusela isikhundla sazo esiphambili kwintsimi yeinjini yomoya. imveliso.
Ukusukela ngo-1986 ukuya kowe-1997, ishishini lamandla laseTshayina beliphuhla ngokuqhubekayo nangesantya esiphezulu, kwaye i-injini yomoya ibona iparamitha ephezulu kunye nomthamo omkhulu.Ngokwezibalo, ekupheleni kuka-1997, umthamo ofakiweyo weeinjini zomphunga eziquka amandla obushushu kunye namandla enyukliya aye afikelela kwi-192 GW, kuquka ne-128 yeeyunithi zamandla obushushu obuyi-250-300 MW, 29 320.0-362.5 MW kunye neeyunithi ezingama-17 500-660mws ;Iiyunithi ezingama-200 MW nangaphantsi nazo ziphuhliswe kakhulu, kuquka iiyunithi ezingama-188 ze-200-210 MW, iiyunithi ezingama-123 ze-110-125 MW kunye neeyunithi ezingama-141 ze-100 MW.Obona bukhulu bomthamo weinjini yamandla enyukliya ngama-900MW.
Ngomthamo omkhulu we-injini ye-steam yesikhululo samandla e-China, ukhuseleko kunye nokuthembeka kwee-blades kunye nokugcinwa kokusebenza kwazo okuphezulu kubaluleke ngakumbi nangakumbi.Ngama-300 MW kunye nama-600 eeyunithi ze-MW, amandla aguqulwa ngeblade yenqanaba ngalinye aphakame kangange-10 MW okanye nama-20 MW.Nokuba i-blade yonakaliswe kancinci, ukuncitshiswa koqoqosho lwe-thermal kunye nokuthembeka kokhuseleko lwe-turbine ye-steam kunye neyunithi yonke yamandla e-thermal ayinakuhoywa.Ngokomzekelo, ngenxa yokulinganisa, ummandla wenqanaba lokuqala lombhobho woxinzelelo oluphezulu uya kuncitshiswa nge-10%, kwaye ukukhutshwa kweyunithi kuya kuncitshiswa nge-3%.Ngenxa yomonakalo obangelwa yimicimbi yangaphandle enzima yangaphandle ebetha i-blade kunye nomonakalo obangelwa ngamasuntswana aqinileyo adiliza i-blade, ukusebenza kwesiteji kunokuncitshiswa nge-1% ~ 3% ngokuxhomekeke kubukhulu bayo;Ukuba i-blade iyaphuka, iziphumo zezi: ukungcangcazela okukhanyayo kweyunithi, ukuxutywa okuguquguqukayo kunye ne-static ye-flow passage, kunye nokulahlekelwa kokusebenza kakuhle;Kwiimeko ezinzima, ukuvalwa ngenkani kunokubangelwa.Ngamanye amaxesha, kuthatha iiveki ezimbalwa ukuya kwiinyanga ezininzi ukubuyisela ii-blades okanye ukulungisa ii-rotors ezonakalisiweyo kunye ne-stators;Kwezinye iimeko, umonakalo we-blade awufunyaniswanga okanye uphathwe ngexesha, okubangela ukuba ingozi iqhubele kwiyunithi yonke okanye i-vibration engalinganiyo yeyunithi ngenxa yokwaphuka kwecala lokugqibela, elinokubangela ukutshatyalaliswa kwayo yonke into. unit, kwaye ilahleko yezoqoqosho iya kuba kumakhulu ezigidi.Imizekelo enjalo ayinqabile ekhaya nakwamanye amazwe.
Amava aqokelelwe kule minyaka idlulileyo abonakalise ukuba nanini na inani elikhulu leeinjini zomphunga ezintsha zifakwa ekusebenzeni okanye xa unikezelo lwamandla kunye nemfuno ingalungelelananga kwaye iiinjini zomphunga zisebenza ixesha elide ngokutenxa kwiimeko zoyilo, ukusilela kweblade. umonakalo obangelwa kuyilo olungafanelekanga, ukuveliswa, ukufakela, ukugcinwa kunye nokusebenza kuya kuboniswa ngokupheleleyo.Njengoko kukhankanyiwe ngasentla, umthamo ofakwe kwii-injini zomphunga ezinkulu kwizikhululo zamandla e-China ziye zanda ngokukhawuleza ngaphezu kweminyaka eyi-10, kwaye imeko entsha yokusebenza kwexesha elide lomthwalo ophantsi weeyunithi ezinkulu kwezinye iindawo sele iqalile ukubonakala.Ngoko ke, kuyimfuneko ukuphanda, ukuhlalutya kunye nokushwankathela zonke iintlobo zomonakalo kwii-blades, ngokukodwa isigaba sokugqibela kunye nokulawula ama-blades esiteji, kunye nokufumanisa imigaqo, ukwenzela ukuba kuqulunqwe amanyathelo okukhusela kunye nokuphucula ukuphepha ilahleko enkulu.
