Injini ngumboneleli wamandla oyimfuneko nobalulekileyo kwimveliso yabantu kunye nobomi.Iinjini ezininzi ziya kuvelisa ubushushu obukhulu ngexesha lokusetyenziswa, kodwa amaxesha amaninzi azazi ukuba zingazisombulula njani.Okubi nangakumbi kukuba abasazi isizathu.Ukufudumeza okubangelwa yimoto kufuneka kube ngowokuqala ukubanjwa ngexesha lokusetyenziswa kwemoto.Makhe sijonge izizathu eziqhelekileyo zokuba kutheni injini ishushu kakhulu.

1. Umsantsa womoya phakathi kwe-stator kunye ne-rotor ye-motor incinci kakhulu, enokuthi iholele ngokulula kungquzulwano phakathi kwe-stator kunye ne-rotor.

Kwiimotor eziphakathi nezincinci, isithuba somoya siqhele ukuba yi-0.2mm ukuya kwi-1.5mm.Xa i-gap yomoya inkulu, i-excitation current iyadingeka ukuba ibe nkulu, ngaloo ndlela ichaphazela amandla ombane wemoto;ukuba i-gap yomoya incinci kakhulu, i-rotor inokuxubha okanye idibanise.Ngokubanzi, ngenxa yokunganyamezeli okunzulu kokuthwala kunye nokunxitywa kunye nokuguqulwa komngxuma wangaphakathi wesigqubuthelo sokugqibela, ii-axes ezahlukeneyo zesiseko somatshini, isigqubuthelo sokugqibela kunye ne-rotor ziya kubangela ukutshayela, okuya kubangela lula injini ukutshisa okanye ukutshisa.Ukuba ukuthwala kufunyenwe ukuba kugugile, kufuneka kutshintshwe ngexesha, kwaye isigqubuthelo sokugqibela kufuneka sitshintshwe okanye sixutywe.Indlela yonyango elula kukufaka isigqubuthelo sokugqibela.

2. Ukungcangcazela okungaqhelekanga okanye ingxolo yenjini ngokulula inokubangela ukuba imotor ibe shushu kakhulu

Le meko yeyokungcangcazela okubangelwa yimoto ngokwayo, uninzi lwayo lubangelwa kukungalungelelani kakuhle kwe-rotor, ukuthwala kakubi, i-shaft egobileyo, amaziko ahlukeneyo e-shaft yesigqubuthelo sokugqibela, isiseko somatshini, kunye ne-rotor, izibophelelo ezivulekileyo, okanye ukungalingani. isiseko sofakelo lweemoto, kunye nokufakelwa okungafanelekanga Inokubangelwa ukuhanjiswa ukusuka ekupheleni komatshini, okufuneka ukhutshwe ngokwemeko ethile.

3. Ukuba ukuthwala akusebenzi kakuhle, ngokuqinisekileyo kuya kubangela ukuba i-motor ifudumale.Ukuba ukuthwala kuyasebenza ngokuqhelekileyo kunokugwetywa ngokuva kunye namava obushushu.

Unokujonga isiphelo sokuthwala ngezandla zakho okanye ithemometha ukujonga ukuba ubushushu bayo buphakathi koluhlu oluqhelekileyo;ungasebenzisa kwakhona intonga yokumamela (intonga yobhedu) ukubamba ibhokisi yokuthwala.Ukuba uva isandi sempembelelo, oko kuthetha ukuba ibhola enye okanye ezininzi zinokutyunyuzwa.Isandi se-hising, oko kuthetha ukuba i-oyile yokuthambisa ye-bearing ayonelanga, kwaye injini kufuneka itshintshe igrisi yokuthambisa rhoqo kwiiyure ezingama-3,000 ukuya kwiiyure ezingama-5,000.

4. I-voltage yonikezelo lwamandla iphezulu kakhulu, i-excitation current iyanda, kwaye i-motor iya kudlula

Umbane ogqithisileyo unokubeka emngciphekweni ukugquma kwemoto, kuyibeka emngciphekweni wokuqhekeka.Xa amandla ombane aphantsi kakhulu, i-torque ye-electromagnetic iya kuncipha.Ukuba i-torque yomthwalo ayinciphisi kwaye isantya se-rotor siphantsi kakhulu, i-slip eyongeziweyo iya kubangela ukuba i-motor ilayishwe kakhulu kwaye ishushu.Ukugqithiswa kwexesha elide kuya kuchaphazela ubomi benjini.Xa i-voltage yesigaba sesithathu i-asymmetrical, oko kukuthi, xa i-voltage yesinye isigaba iphezulu okanye iphantsi, i-current yesigaba esithile iya kuba nkulu kakhulu, kwaye i-motor iya kutshisa.Ngelo xesha, i-torque iya kuncipha kwaye isandi esithi "humming" siya kukhutshwa.Emva kwexesha elide, ukujija kuya konakala.

Ngamafutshane, kungakhathaliseki ukuba i-voltage iphezulu kakhulu, iphantsi kakhulu okanye i-voltage i-asymmetrical, okwangoku iya kwanda, kwaye i-motor iya kutshisa kwaye yonakalise i-motor.Ngoko ke, ngokomgangatho wesizwe, ukutshintshwa kwamandla ombane ombane wemoto akufanele kudlule i-± 5% yexabiso elilinganisiweyo, kwaye amandla okukhutshwa kwemoto anokugcina ixabiso elilinganisiweyo.I-voltage yombane we-motor ayivumelekanga ukuba idlule ± 10% yexabiso elilinganisiweyo, kwaye umahluko phakathi kwezigaba ezintathu zombane wombane akufanele udlule i-± 5% yexabiso elilinganisiweyo.

5. I-winding short circuit, i-turn-to-turn short circuit, i-phase-to-phase short circuit kunye ne-winding open circuit.

Emva kokuba i-insulation phakathi kweengcingo ezimbini ezikufutshane kwi-winding yonakalisiwe, abaqhubi ababini bayathintana, okubizwa ngokuba yi-winding short circuit.Iisekethe ezimfutshane ezijikelezayo ezenzeka kwi-winding efanayo zibizwa ngokuba zii-turn-to-turn short circuits.Isekethe emfutshane ejikajikayo eyenzeka phakathi kwamajiko-jiko amabini ibizwa ngokuba yi-module-to-phase short circuit.Kungakhathaliseki ukuba yeyiphi na, iya kwandisa i-current yesigaba esinye okanye izigaba ezibini, ibangele ukufudumeza kwendawo, kunye nobudala be-insulation ukonakalisa i-motor.Ukuvunguza kwesekethe evulekileyo kubhekiselele kukusilela okubangelwa yi-stator okanye i-rotor winding ye-motor eyaphukileyo okanye ukuvuthelwa.Nokuba yisekethe emfutshane okanye isekethe evulekileyo yokujija, inokubangela ukuba imotor ifudumale okanye itshise.Ngoko ke, kufuneka ivalwe ngokukhawuleza emva kokuba oku kwenzekile.

6. Izinto zivuza kwi-motor, enciphisa ukugquma kwe-motor, ngaloo ndlela inciphisa ukunyuka kobushushu obuvumelekileyo be-motor.

Ukuba izinto eziqinileyo okanye uthuli lungena kwi-motor ukusuka kwibhokisi ye-junction, luya kufikelela kwisithuba somoya phakathi kwe-stator kunye ne-rotor ye-motor, ebangela ukuba i-motor itshayelwe, de kube i-insulation ye-motor winding igugile, kwaye i-motor yonakaliswe. okanye ichithiwe.Ukuba i-media ye-liquid kunye ne-gaseous ivuza kwi-motor, iya kubangela ngokuthe ngqo ukuba i-insulation ye-motor yehle kwaye ihambe.Ulwelo ngokubanzi kunye nokuvuza kwerhasi kunezi mpawu zilandelayo:

(1) Ukuvuza kwezikhongozeli ezahlukeneyo kunye nemibhobho yokuhambisa, ukuvuza kwezitywina zomzimba wempompo, izixhobo zokugungxula kunye nomhlaba, njl.

(2) Emva kokuvuza kwe-oyile yoomatshini, ingena kwi-motor ukusuka kwisithuba sebhokisi yokuthwala yangaphambili.

(3) Isitywina se-oyile sesinciphisi esiqhagamshelwe kwinjini siyanxitywa, kwaye i-oyile yomatshini yokuthambisa ingena ecaleni kweshafti yemoto.Emva kokuqokelela ngaphakathi kwi-motor, inyibilikisa i-varnish yokufaka i-motor, ethi ngokuthe ngcembe inciphise ukusebenza kwe-insulation ye-motor.

7. Phantse isiqingatha sokutsha kwemoto kubangelwa ukungabikho kwesigaba sokusebenza kwemoto

Ukungabikho kwesigaba kudla ngokubangela ukuba i-motor ingaphumeleli okanye isantya sicotha emva kokuqala, okanye kukho isandi esithi "humming" xa ukujikeleza kubuthathaka kwaye ukwanda kwangoku.Ukuba umthwalo kwi-shaft awutshintshi, i-motor igcwele kakhulu, kwaye i-stator yangoku iya kufikelela kumaxesha ama-2 ixabiso elilinganisiweyo okanye ngaphezulu.Injini iya kutshisa okanye itshise ngexesha elifutshane.Ezona zizathu zokusilela komsebenzi wesigaba zezi zilandelayo:

(1) Ukuba esinye isigaba sentambo yombane sinqunyulwe ngenxa yokusilela kwezinye izixhobo, ezinye izixhobo zesigaba esithathu eziqhagamshelwe kumgca ziya kuqhuba ngaphandle kwesigaba.

(2) Esinye isigaba se-breaker circuit okanye i-contactor siphuma kwisigaba ngenxa yokutshiswa kombane we-bias okanye uqhagamshelwano olubi.

(3) Ukungabikho kwesigaba esibangelwa ukuguga kunye nokugqoka komgca ongenayo wemoto.

(4) Inqanaba elinye lokujija i-motor liphukile, okanye isiqhagamshelo sesigaba esinye kwibhokisi ye-junction sikhululekile.

8. Ezinye izinto ezingezizo ezomatshini kunye nezombane ezibangela ukusilela

Ukunyuka kwamaqondo obushushu emoto okubangelwa zezinye iziphene ezingezizo ezomatshini kunye nezombane nazo zinokukhokelela ekungaphumeleli kwemoto kwiimeko ezinzima.Ukuba ubushushu be-ambient buphezulu, i-motor ayinayo ifeni, ifeni ayiphelelanga, okanye isigqubuthelo sefeni silahlekile.Kule meko, kuyimfuneko ukunyanzela ukupholisa ukuqinisekisa ukungena komoya okanye ukubuyisela ii-fan blades, ngaphandle koko ukusebenza okuqhelekileyo kwemoto akunakuqinisekiswa.

Ukushwankathela, ukuze usebenzise indlela echanekileyo yokujongana neziphene zeemoto, kuyimfuneko ukuba uqhelane neempawu kunye nezizathu zeempazamo eziqhelekileyo zeemoto, ubambe izinto eziphambili, kwaye uqhube ukuhlolwa kunye nokugcinwa rhoqo.Ngale ndlela, i-detours inokuphetshwa, ixesha lingagcinwa, iimpazamo zinokupheliswa ngokukhawuleza, kwaye i-motor ingaba kwimeko yokusebenza eqhelekileyo.Ukuze kuqinisekiswe imveliso eqhelekileyo yocweyo.
