Kwintsimi yemveliso yamashishini kunye nokuqhuba amandla,isigaba sesithathu se-asynchronous motor yombanes zizixhobo ezingundoqo, kwaye ukuthembeka kwazo kubalulekile. Esinye sezibonakaliso eziphambili zokulinganisa ukuthembeka kwemoto lixesha eliphakathi phakathi kokusilela (MTBF). Ukuqonda esi salathisi kunye nokuvavanya ukuthembeka kwayo kunye neendlela zokuqinisekisa kubaluleke kakhulu kubasebenzisi ukuba bakhethe ngokuchanekileyo kwaye basebenzise ngokufanelekileyo iinjini.
Ixesha eliphakathi phakathi kokusilela libhekisa kumndilili wobude bexesha apho injini inokusebenza ngokuqhubekayo ngaphandle kokusilela phantsi kweemeko ezithile kunye nexesha. Kwinqanaba eliphezulu leenjini ezintathu ze-asynchronous motors, i-MTBF yabo ichatshazelwa zizinto ezininzi ezinjengomgangatho woyilo, inkqubo yokuvelisa, ukukhetha izinto, kunye nendawo yokusebenza. Ngaphantsi kokusetyenziswa kunye nokugcinwa okuqhelekileyo, i-MTBF yeumgangatho ophezulu kunye nomgangatho ophezulu we-asynchronous motor yesigaba sesithathus inokufikelela kumashumi amawaka eeyure okanye nangaphezulu.
Kukho umahluko kwi-MTBF yeenjini zabavelisi abahlukeneyo, iimodeli kunye neenkcukacha. Iimpawu ezaziwayo-kakuhle kunye nabavelisi betekhnoloji ephezulu banokuyiphucula kakhulu i-MTBF yeemoto ngokusebenzisa i-R&D innovation, ukusetyenziswa kwezinto ezikumgangatho ophezulu kunye neenkqubo ezichanekileyo. Kwimimandla eneemfuno zokuthembeka eziphezulu kakhulu ezifana nemigca yokuvelisa i-automation automation, izixhobo zonyango, i-aerospace, njl., iimotor kufuneka zibe ne-MTBF ende ukuqinisekisa ukuqhubeka kwemveliso kunye nokhuseleko.
Uvavanyo lokuthembeka kunye neendlela zokuqinisekisa iimotor
Ukuqinisekisa ukuthembeka kweemoto, uthotho lweendlela zokuvavanya kunye nokuqinisekisa zisetyenziswa ekuphuhliseni nasekuveliseni iimoto.
Uvavanyo lokuziqhelanisa nokusingqongileyo: Imoto kufuneka ivavanywe phantsi kobushushu obuhlukeneyo, ukufuma, uxinzelelo lomoya kunye nezinye iimeko. Ukusebenza kwemoto kunye nokuthembeka kwimeko yemozulu eshushu kuvavanywa ngokulinganisa ubume bendawo yobushushu obuphezulu, amandla okuqalisa emoto kunye nokusebenza kwe-insulation kuvavanywa kwindawo yobushushu obuphantsi, kwaye uvavanyo lokufuma luqinisekisa ukuxhathisa ukufuma kwemoto kunye nokusebenza kokufakelwa kombane kwiindawo ezifumileyo. Olu vavanyo lunceda ukufumanisa iingxaki ezinokwenzeka ngemoto phantsi kweemeko ezahlukeneyo zokusingqongileyo kunye nokuthatha amanyathelo okuphucula.
Uvavanyo lokuhlala ixesha elide: Linganisa imeko yokusebenza kwexesha elide kwemoto, jonga utshintsho kwiiparamitha ezinje ngokunyuka kobushushu bemoto, ukungcangcazela, ingxolo, nokuba kukho impazamo. Kwangaxeshanye, yenza rhoqo imisebenzi yokuqalisa kunye nokuyeka ukuvavanya ukuqala kunye nokuyeka ukusebenza kwemoto kunye nokuziqhelanisa nokusebenza rhoqo.
Uvavanyo lokusebenza kombane: Ukulinganisa kunye nokuhlalutya iiparamitha zombane zemoto ezifana nombane, okwangoku, amandla, kunye nemeko yamandla ukuqinisekisa ukuthotyelwa kweemfuno zoyilo kunye nemigangatho efanelekileyo. Yenza iimvavanyo zokumelana nokufakelwa kunye nokumelana novavanyo lombane ukuze uqinisekise ukusebenza kwe-insulation kunye nokhuseleko lombane lwemoto.
Uvavanyo lokusebenza koomatshini: Vavanya amandla, ukuqina, ukuxhathisa ukunxiba kunye nezinye iipropathi zeebheringi zemoto, ishafti, izindlu kunye nezinye iindawo zoomatshini. Ngokulinganisa ukusebenza phantsi kweemeko ezahlukeneyo zomthwalo, umthamo womthwalo wokuthwala kunye nobomi buvavanywa; i-shaft iphantsi kovavanyo lwamandla e-torsional ukuqinisekisa ukuba ayiyi kuphuka okanye ingaphumeleli ngexesha lokusebenza.
Ixesha lokusebenza lemoto elingenazinkathazo luphawu olubalulekileyo lokuthembeka kwayo, kwaye uvavanyo lokuthembeka kunye neendlela zokuqinisekisa zezona ndlela ziphambili zokuqinisekisa umgangatho kunye nokusebenza kwemoto. Xa ukhetha iishishiniimoto, abasebenzisi kufuneka banikele ingqalelo kwi-MTBF yayo kunye nokuvavanya ukuthembeka kunye neendlela zokuqinisekisa ezisetyenziswa ngumenzi ukukhetha iimveliso zeemoto kunye nokusebenza okuthembekileyo kunye nomgangatho ogqwesileyo wokubonelela ngenkxaso yamandla ezinzileyo kwiimeko ezahlukeneyo zesicelo.
