Izizathu zokutshiswa kwemoto zinokwahlulwa zibe: umthwalo, unikezelo lwamandla, ukugqunywa kwemoto,isigaba esimiselweyo
1.Isigaba esihlala sihleli
Isizathu:Ngokuqhelekileyo ngenxa yokungabikho kwamandla esigaba. (i-1 isigaba esingabonelelwanga okanye i-voltage enganeleyo yokubonelela) .Okanye i-contactor contact point in the line ayivalwanga.Indawo yokuqhagamshelwa kwentambo iyaqhawula, ikhulule okanye i-contact positions i-oxidizes ibangela njalo njalo.
Uphawu:Isigaba esinye okanye ezibini (inqanaba lesi-4) kwii-windings zonke zimnyama, ikhoyili yonakaliswe ngokulinganayo.
2.Ukulayisha ngaphezulu
Isizathu:Ngokuqhelekileyo lixesha elide lokuhamba ngaphezulu kwangoku, ukutshisa kakhulu, ukuqala rhoqo okanye ukuqhawula,iingcingo impazamo.
Uphawu:Ukujija yonke into ijika ibemnyama, isibophelelo ekugqibeleni sijika sibe mnyama kwaye sibe brittle okanye sophuke.
3.Ithuba lokuphumla
Isizathu:Ukuqhawuka kocingo olune-enameled kwinkqubo yokwenziwa kweemoto, kwaye amanzi, iasidi, kunye nezinye izinto eziyingozi kwinkqubo nazo zinokubangela ukusilela.
Uphawu:Ukujija kutshiswe ngokuyinxenye, ngokuqhelekileyo umngxuma wemoto ucocekile, kukho indawo enye kuphela yokuqhushumba.
4.Electrode inqanaba ezimbini
Isizathu:Iphepha le-interphase alikho, okanye iphepha le-interphase (i-casing) liphukile.
Uphawu:Imoto iyatsha phakathi kwezigaba ezibini.
5.Uqhankqalazo
Isizathu:Umgama ongonelanga phakathi kwekhoyili kunye nesitulo sokuvala isiphelo.
Uphawu:Kukho amabala okutsha kumacala omabini phakathi kwekhoyili kunye nesigqubuthelo sokuphela.
Ukuthintela njani ukuba injini ingatshi?
1.Gcina injini icocekile
Injini kufuneka isoloko igcina isiziba somoya sicocekile ngexesha lokusebenza.
Ukuba uthuli, i-oyile kunye namanzi zitsalwa kwi-motor, i-short circuit medium yenziwa ukuba yonakalise i-insulation yocingo.
Ibangela i-interturn short circuit, ukunyuka kwangoku, ukunyuka kweqondo lokushisa, kutshisa i-motor.
2.Sebenza phantsi komthwalo olinganisiweyo
Umsebenzi wokulayisha ngaphezulu kweemoto, esona sizathu siphambili kukuba umthwalo wokutsala mkhulu kakhulu, umbane uphantsi kakhulu, okanye oomatshini abaqhutywayo babambekile.
Xa i-motor ihamba kwindawo yomthwalo ogqithiseleyo, isantya semoto siyancipha, ukunyuka kwangoku, ukunyuka kweqondo lokushisa kunye ne-coil overheats.Ukuba i-motor igcwele ixesha elide, iya kutshisa phantsi kokusilela kokuguga kwe-insulation kwiqondo lokushisa eliphezulu. , esona sizathu siphambili sokuba injini ivuthe.
3.Gcina inqanaba lesithathu langoku lizinzileyo
Kwiimotor ze-asynchronous zesigaba sesithathu, umahluko phakathi kwexabiso eliphakathi kwaso nasiphi na isigaba sangoku kunye nesinye isigaba sangoku asivumelekanga ukuba sidlule i-10% ukwenzela ukuba kuqinisekiswe ukusebenza okukhuselekileyo nokuqhelekileyo kwemoto.
Ukuba umyinge wexabiso lomyinge wesigaba esisodwa kunye nexabiso eliqhelekileyo lesinye isigaba esibini sangoku sidlula umda omiselweyo, kubonisa ukuba i-motor inephutha.Isizathu kufuneka sifumaneke kwaye impazamo inokususwa ngaphambi kokuba injini iqhubeke nokusebenza, kungenjalo i-motor iya kutshiswa.
4.Gcina ubushushu obuqhelekileyo
Ubushushu bokuthwala, i-stator, i-enclosure kunye nezinye iindawo ze-motor ziya kujongwa rhoqo malunga nokungahambi kakuhle, ngakumbi kwi-motor ngaphandle kwe-voltage, izibonelelo zangoku kunye ne-frequency esweni kunye nezibonelelo zokukhusela ukugqithiswa, kwaye ukubeka iliso kokunyuka kobushushu kubaluleke kakhulu.
Ukuba ukunyuka kweqondo lokushisa kufuphi ne-bearing kufunyenwe kuphezulu kakhulu, kufuneka kumiswe ngokukhawuleza ukujonga ukuba i-bearing yonakaliswe okanye ifutshane neoli.Ukuba iibheringi zonakaliswe, kufuneka zitshintshwe ngeebheringi ezintsha ngaphambi kokusebenza.Ukuba iibheringi zifutshane ngeoli, igrisi kufuneka yongezwe;ngaphandle koko, iibheringi ziya konakala ngakumbi, kubangele ukuwa, okuya kutshabalalisa i-motor ngokutshayela.
5.Qwalasela ukungcangcazela, ingxolo, kunye namavumba
Ukuba i-motor iyashukuma, iya kubangela ukuba i-non-coaxiality ye-motor edityaniswe nayo inyuke, eya kwandisa umthwalo we-motor, yandisa i-current, kwaye yandise ubushushu kunye nokutshisa i-motor.
Ngoko ke, xa i-motor isebenza, kuyimfuneko ukujonga rhoqo ukuba i-anchor bolts, i-cover end of the motor kunye ne-bearing pressure cover ikhululekile, kwaye ingaba isixhobo sokudibanisa sithembekile.Ukuba kukho nayiphi na ingxaki efunyenweyo, kufuneka isonjululwe kwangethuba.
6.Qinisekisa ukusebenza okuqhelekileyo kwesixhobo sokuqala
Ukugcinwa okuphambili komqalisi kukucoca kunye nokukhawuleza.Ukuba uqhagamshelwano lwe-contactor aluhlambulukanga, ukuchasana koqhagamshelwano kuya kwandiswa, kubangele ukutshiswa koqhagamshelwano, kubangele ukungabikho kwesigaba kunye nokutshiswa kwemoto.I-rust corrosion kunye nothuli. ukuqokelelwa kwengundoqo yekhoyili yemagnethi ye-contactor iya kwenza i-coil ingavali ngokuqinileyo kwaye ikhuphe ingxolo enamandla, ikhulise i-coil current, itshise ikhoyili kwaye ibangele iimpazamo.
Izixhobo zokulawula umbane kufuneka zibe kwindawo eyomileyo, engena umoya kwaye kulula ukuyisebenzisa kwi-position.Susa uthuli rhoqo, qinisa zonke izikrufu ze-wiring, khangela ukuba uqhagamshelwano lwe-contactor lulungile kwaye luthembekile, kwaye ingaba iinxalenye zoomatshini zinovakalelo kwaye zichanekile.Gcina i-motor ikwimeko efanelekileyo yobugcisa. , ukuze i-motor ikwazi ukuqala kakuhle ngaphandle kokutshisa.
