Injini ingumhlinzeki wamandla obalulekile futhi obalulekile ekukhiqizeni nasekuphileni kwabantu. Amamotho amaningi azokhiqiza ukushisa okukhulu phakathi nokusetshenziswa, kodwa ezikhathini eziningi awazi ukuthi angakuxazulula kanjani. Okubi kakhulu wukuthi abasazi isizathu. Ukushisa okuwumphumela wenjini kufanele kube ngowokuqala ukubanjwa ngesikhathi kusetshenziswa injini. Ake sibheke izizathu ezivamile zokuthi kungani injini ishisa kakhulu.

1. Igebe lomoya phakathi kwe-stator ne-rotor ye-motor lincane kakhulu, elingase liholele kalula ekushayisaneni phakathi kwe-stator ne-rotor.

Kumamotho amaphakathi namancane, igebe lomoya livamise ukuba ngu-0.2mm kuya ku-1.5mm.Lapho igebe lomoya likhulu, i-excitation current iyadingeka ukuba ibe nkulu, ngaleyo ndlela ithinte isici samandla enjini; uma igebe lomoya lincane kakhulu, i-rotor ingase iguqe noma ingqubuzane.Ngokuvamile, ngenxa yokungabekezelelani okujulile kwe-bearing kanye nokuguga nokuguqulwa kwembobo yangaphakathi yekhava yokugcina, izimbazo ezihlukene zesisekelo somshini, ikhava yokugcina kanye ne-rotor kuzodala ukukhukhula, okuzokwenza kalula injini ukushisa noma ukushiswa.Uma ukuthwala kutholakala ukuthi kugugile, kufanele kushintshwe ngesikhathi, futhi isembozo sokugcina kufanele sishintshwe noma sixutshwe. Indlela elula yokwelapha ukufaka ikhava yokugcina.

2. Ukudlidliza okungavamile noma umsindo wenjini kungabangela kalula ukuthi injini ishise ngokweqile

Lesi simo singesokudlidliza okubangelwa injini ngokwayo, iningi lazo elibangelwa ibhalansi engalungile ye-rotor, ukuthwala okubi, i-shaft egobile, izikhungo ze-shaft ezihlukene zekhava yokugcina, isisekelo somshini, ne-rotor, izinsimbi eziqinile, noma ukungalingani. isisekelo sokufakwa kwezimoto, nokufakwa okungalungile Kungase kubangelwa ukudluliselwa okuvela ekupheleni komshini, okufanele kukhishwe ngokuvumelana nesimo esithile.

3. Uma ukuthwala kungasebenzi kahle, kuzokwenza ukuthi injini ishise. Ukuthi i-areyitha isebenza ngokujwayelekile yini kungahlulelwa ngokuzwa nezinga lokushisa.

Ungahlola i-bearing end ngezandla zakho noma i-thermometer ukuze uthole ukuthi izinga lokushisa layo lingaphakathi kwebanga elijwayelekile; ungasebenzisa futhi induku yokulalela (induku yethusi) ukuze uthinte ibhokisi lokuthwala. Uma uzwa umsindo onomthelela, kusho ukuthi ibhola elilodwa noma amaningana angase achotshozwe. Umsindo we-hissing, kusho ukuthi uwoyela wokugcoba we-bearing awanele, futhi injini kufanele iguqule amafutha okugcoba njalo ngamahora angu-3,000 kuya emahoreni angu-5,000.

4. I-voltage yokunikezwa kwamandla iphezulu kakhulu, i-excitation current iyanda, futhi injini izoshisa ngokweqile

I-voltage eyeqile ingalimaza ukufakwa kwezimoto, kubeke engcupheni yokonakala.Lapho i-voltage yokuphakelwa kwamandla iphansi kakhulu, itorque kagesi izokwehla. Uma i-torque yokulayisha inganciphi futhi isivinini se-rotor siphansi kakhulu, isiliphu esikhulayo sizokwenza ukuthi imoto igcwale futhi ishise. Ukugcwala ngokweqile kwesikhathi eside kuzothinta impilo yenjini.Lapho i-voltage yezigaba ezintathu i-asymmetrical, okungukuthi, lapho i-voltage yesigaba esisodwa iphezulu noma iphansi, i-current yesigaba esithile izoba nkulu kakhulu, futhi injini izoshisa. Ngesikhathi esifanayo, i-torque izokwehla futhi umsindo othi "humming" uzokhishwa. Ngemva kwesikhathi eside, i-winding izolimala.

Ngamafuphi, kungakhathaliseki ukuthi i-voltage iphezulu kakhulu, iphansi kakhulu noma i-voltage i-asymmetrical, yamanje izokhula, futhi injini izoshisa futhi ilimaze injini.Ngakho-ke, ngokwezinga likazwelonke, ukuguqulwa kwamandla kagesi we-motor akufanele kudlule ± 5% yenani elilinganiselwe, futhi amandla okukhipha emoto angagcina inani elilinganiselwe.I-voltage yokuphakelwa kwamandla enjini ayivunyelwe ukuba yeqe ku-±10% yenani elilinganiselwe, futhi umehluko phakathi kwama-voltage okuphakela amandla ezigaba ezintathu akufanele wedlule ku-±5% yenani elilinganiselwe.

5. Isekhethi emfishane evunguzayo, isifunda esifushane sokujika siphenduke, isekethe emfishane yesigaba ukuya kwesinye kanye nesekhethi evulekile evunguzayo

Ngemva kokulimala phakathi kwezintambo ezimbili eziseduze ekujikeni, amakhondaktha amabili ayathintana, okubizwa ngokuthi i-winding short circuit.Amasekhethi amafushane ajikayo enzeka endaweni efanayo abizwa ngokuthi ama-turn-to-turn short circuits.Isifunda esifushane esimazombezombe esenzeka phakathi kwama-winding ezigaba ezimbili sibizwa ngokuthi isifunda esifushane sesigaba ukuya kwesinye.Kungakhathaliseki ukuthi iyiphi, izokwandisa ukusebenza kwesigaba esisodwa noma izigaba ezimbili, ibangele ukushisa kwendawo, futhi iguge ukufakwa ukuze kulimaze injini.Ukuvunguza kwesekethe evulekile kubhekisela ekuhlulekeni okubangelwa ukuma kwe-stator noma i-rotor ye-motor ephukile noma eshaywa.Kungakhathaliseki ukuthi isifunda esifushane noma isekethe evulekile yokujikajika, ingabangela injini ukuthi ishise noma ishise.Ngakho-ke, kufanele ivalwe ngokushesha ngemva kokuba lokhu sekwenzekile.

6. Impahla ivuza kumotho, okunciphisa ukufakwa kwe-motor, ngaleyo ndlela kunciphise izinga lokushisa elivumelekile lemoto.

Uma izinto eziqinile noma uthuli lungena emotweni lusuka ebhokisini lokuhlangana, luzofinyelela igebe lomoya phakathi kwe-stator ne-rotor ye-motor, okubangela ukuthi i-motor ishanele, kuze kube yilapho i-insulation ye-motor winding igugile, futhi injini yonakaliswa. noma elahliwe.Uma imidiya ewuketshezi negesi ivuza emoteni, izobangela ngokuqondile ukuthi insulation yemoto yehle futhi ihambe.Ukuvuza okujwayelekile koketshezi negesi kunezimpawu ezilandelayo:

(1) Ukuvuza kweziqukathi ezahlukene kanye namapayipi okulethwa, ukuvuza kwezigxivizo zempompo yomzimba, okokusebenza okushaywayo kanye nomhlabathi, njll.

(2) Ngemva kokuvuza kwamafutha ayimishini, angena enjini esuka esikhaleni sebhokisi eliphethe ngaphambili.

(3) Isigxivizo sikawoyela sesinciphisi esixhunywe enjinini siyagugiswa, futhi amafutha okugcoba ayimishini angena eduze kwe-motor shaft. Ngemuva kokunqwabelana ngaphakathi kwe-motor, incibilikisa i-varnish yokufaka i-motor, enciphisa kancane kancane ukusebenza kwe-insulation ye-motor.

7. Cishe ingxenye yokusha kwemoto ibangelwa ukuntuleka kokusebenza kwesigaba semoto

Ukuntuleka kwesigaba ngokuvamile kubangela ukuba injini yehluleke ukugijima noma isivinini sihamba kancane ngemva kokuqala, noma kukhona umsindo "wokuhumza" lapho ukujikeleza kubuthakathaka futhi ukwanda kwamanje.Uma umthwalo ku-shaft ungashintshi, i-motor igcwele kakhulu, futhi i-stator yamanje izofinyelela izikhathi ezingu-2 inani elilinganiselwe noma ngaphezulu.Injini izoshisa noma iphele ngesikhathi esifushane.Izizathu eziyinhloko zokuntuleka kokusebenza kwesigaba yilezi ezilandelayo:

(1) Uma isigaba esisodwa sentambo kagesi sinqanyulwa ngenxa yokwehluleka kwezinye izinto zokusebenza, ezinye izinto zezigaba ezintathu ezixhunywe kulayini zizosebenza ngaphandle kwesigaba.

(2) Isigaba esisodwa se-circuit breaker noma isixhumi esixhumene naye siphumile esigabeni ngenxa yokushiswa kwamandla kagesi okuchema noma ukuthintana kahle.

(3) Ukuntuleka kwesigaba okubangelwa ukuguga nokuguga komugqa ongenayo wenjini.

(4) Ukusonteka kwesigaba esisodwa senjini kuphukile, noma isixhumi sesigaba esisodwa ebhokisini lokuhlangana sikhululekile.

8. Ezinye izimbangela zokungaphumeleli kwemishini kanye nogesi

Ukwenyuka kwezinga lokushisa kwemoto okubangelwa amanye amaphutha angewona emishini kanye nawogesi kungase kuholele ekuhlulekeni kwezimoto ezimweni ezimbi kakhulu.Uma izinga lokushisa le-ambient liphezulu, injini ayinaso isiphephetha-moya, ifeni ayiphelele, noma ikhava yabalandeli ayikho.Kulokhu, kuyadingeka ukuphoqelela ukupholisa ukuze uqinisekise ukungena komoya noma ukubuyisela ama-fan blades, ngaphandle kwalokho ukusebenza okujwayelekile kwemoto akukwazi ukuqinisekiswa.

Ukufingqa, ukuze usebenzise indlela efanele yokubhekana namaphutha ezimoto, kuyadingeka ukujwayelana nezici nezimbangela zamaphutha avamile ezimoto, ubambe izici ezibalulekile, futhi uhlole njalo nokunakekela.Ngale ndlela, ama-detours angagwenywa, isikhathi singagcinwa, amaphutha angaqedwa ngokushesha ngangokunokwenzeka, futhi injini ingaba sesimweni esivamile sokusebenza.Ukuze kuqinisekiswe ukukhiqizwa okuvamile kwe-workshop.
