1. Igebe lomoya phakathi kwe-stator ne-rotor ye-motor lincane kakhulu, okulula ukubangela ukungqubuzana 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 okungathi sína kokuthwala kanye nokuguga nokuguqulwa kwembobo yangaphakathi yekhava yokugcina, izimbazo ezihlukene zesisekelo somshini, isembozo sokugcina kanye ne-rotor kubangela ukushanela, okungabangela kalula injini ukushisa noma ukushiswa.Uma ukuthwala kutholakala ukuthi kugugile, kufanele kushintshwe ngesikhathi, futhi isembozo sokugcina kufanele sishintshwe noma sixutshwe.Indlela yokwelapha elula iwukufaka umkhono kukhava yokugcina.
2. Ukudlidliza okungavamile noma umsindo wenjini kungabangela kalula ukushisa kwenjini
Lesi simo singesokudlidliza okubangelwa injini ngokwayo, iningi lazo elibangelwa ukulingana okungalungile kwe-rotor, kanye nama-bearings ampofu, ukugoba kwe-shaft ejikelezayo, izikhungo ezihlukene ze-axial zekhava yokugcina, isisekelo somshini kanye ne-rotor. , izinsimbi eziqinile noma isisekelo sokufakwa kwemoto esingalingani, futhi ukufakwa akukho endaweni.Kungase futhi kubangelwe ukuphela komshini, okufanele kukhishwe ngokuvumelana nezimo ezithile.
3. Ukuthwala akusebenzi kahle, okuzokwenza ukuthi injini ishise
Ukuthi ukuthwala kuyasebenza ngokujwayelekile kungahlulelwa ngokuzwa nezinga lokushisa.Sebenzisa isandla noma ithemometha ukuthola isiphetho ukuze unqume ukuthi izinga lokushisa layo lingaphakathi kwebanga elivamile;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 ishintshwe ngamafutha njalo emahoreni angu-3,000 kuya kwangu-5,000 okusebenza.
4. I-voltage yokunikezwa kwamandla iphezulu kakhulu, i-excitation current iyanda, futhi injini izoshisa ngokweqile
Ama-voltage amaningi angalimaza ukufakwa kwezimoto, kubeke engcupheni yokonakala.Uma i-voltage yokuphakelwa kwamandla iphansi kakhulu, itorque kagesi izoncishiswa.Uma i-torque yomthwalo ingancishisiwe futhi isivinini se-rotor siphansi kakhulu, ukwanda kwesilinganiso se-slip kuzobangela ukuthi imoto igcwale futhi ifudumale, futhi ukulayishwa kwesikhathi eside kuzothinta impilo yemoto.Lapho i-voltage yezigaba ezintathu i-asymmetric, okungukuthi, lapho i-voltage yesigaba esisodwa iphezulu noma iphansi, i-current yesigaba esithile izoba nkulu kakhulu, injini izoshisa, futhi ngesikhathi esifanayo, i-torque izoba. kuncishiswe, futhi kukhishwe umsindo othi "humming", okuzolimaza ukuvunguza isikhathi eside.
Ngamafuphi, kungakhathaliseki ukuthi i-voltage iphezulu kakhulu, iphansi kakhulu noma i-voltage i-asymmetrical, yamanje izokhula, futhi injini izoshisa futhi ilimaze injini.Ngakho-ke, ngokwendinganiso kazwelonke, ukuguqulwa kwamandla kagesi wemoto akufanele kudlule u-±5% yenani elilinganiselwe, futhi amandla okukhipha imoto 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 kwentambo phakathi kwezintambo ezimbili ezincikene ekujikeni, amakhondatha amabili ayashayisana, okubizwa ngokuthi i-short circuit.Isifunda esifushane esimazombezombe esenzeka kumjikelezo ofanayo ubizwa ngokuthi i-turn-to-turn short circuit.Isifunda esifushane esimazombezombe esenzeka phakathi kwamajika ezigaba ezimbili sibizwa ngokuthi i-interphase short circuit.Kungakhathaliseki ukuthi iyiphi, izokwandisa ukusebenza kwesigaba esisodwa noma izigaba ezimbili, ibangele ukushisa kwendawo, futhi ilimaze injini ngenxa yokuguga kokufakwa.Isekhethi evulekile yomoya isho iphutha elibangelwa ukuphuka noma ukushiswa kwe-stator noma i-rotor winding ye-motor.Ukuthi i-wiring in short-circuited noma ivulekile-circuited, ingase ibangele injini ukushisa noma ngisho ishise.Ngakho-ke, kufanele imiswe ngokushesha ngemva kokwenzeka kwalokhu.
6. Impahla ivuza ngaphakathi kwenjini, okunciphisa ukufakwa kwenjini, ngaleyo ndlela kwehlise izinga lokushisa elivumelekile lemoto.
Izinto eziqinile noma uthuli olungena enjini lusuka ebhokisini lokuhlangana luzofinyelela igebe lomoya phakathi kwe-stator ne-rotor yenjini, okubangela ukuthi injini ishanele, kuze kube yilapho ukufakwa kwe-motor winding kugugile, okubangele ukuthi injini yonakale noma ichitheke. .Uma i-liquid ne-gas medium kuvuza kumotho, kuzobangela ngokuqondile ukuthi insulela yemoto yehle futhi ihambe.
Ukuvuza okujwayelekile koketshezi negesi kunokubonakaliswa okulandelayo:
(1) Ukuvuza kweziqukathi ezihlukahlukene kanye namapayipi okudlulisa, ukuvuza kwezigxivizo zempompo yomzimba, okokusebenza okushaywayo kanye nomhlabathi, njll.
(2) Ngemva kokuvuza kwamafutha ayimishini, angena enjini esuka esikhaleni sebhokisi eliphethe ngaphambili.
(3) Izigxivizo zikawoyela njengesinciphisi esixhunywe enjini ziyagugiswa, futhi uwoyela wokugcoba oyimishini ungena eduze kwe-motor shaft.Ngemva kokunqwabelana ngaphakathi kwe-motor, upende we-motor insulating uyancibilika, ukuze ukusebenza kwe-insulation ye-motor kuncishiswe kancane kancane.
7. Cishe isigamu sokushiswa kwemoto kubangelwa ukuntuleka kokusebenza kwesigaba semoto
Ukuntuleka kwesigaba kuvame ukubangela ukuthi injini yehluleke ukusebenza, noma ukuzungeza kancane ngemva kokuqala, noma ukukhiqiza umsindo “ohumming” lapho amandla engazungezi futhi ukwanda kwamanje.Uma umthwalo ku-shaft ungashintshi, i-motor igcwele kakhulu futhi i-stator yamanje izoba izikhathi ezingu-2 inani elilinganiselwe noma ngaphezulu.Esikhathini esifushane, injini izoshisa noma iphele.bangela ukulahlekelwa kwesigaba.
Izizathu eziyinhloko yilezi:
(1) Ukuphela kukagesi kwesigaba esisodwa okubangelwa ukungasebenzi kwezinye izisetshenziswa entanjeni kagesi kuzobangela ukuthi ezinye izinto zezigaba ezintathu ezixhunywe entanjeni zisebenze ngaphandle kwesigaba.
(2) Isigaba esisodwa se-circuit breaker noma isixhumi esixhumene naye siphelelwe yisikhathi ngenxa yokushiswa kwamandla kagesi achemile noma ukuthintana kabi.
(3) Ukulahleka kwesigaba ngenxa yokuguga, ukuguga, njll. kolayini ongenayo wenjini.
(4) Ukujika kwesigaba esisodwa senjini kuyisekethe evulekile, noma isixhumi sesigaba esisodwa ebhokisini lokuhlangana sikhululekile.
8. Ezinye izimbangela zokuhluleka kukagesi okungeyona imishini
Ukwenyuka kwezinga lokushisa kwemoto okubangelwa amanye amaphutha kagesi okungewona ama-mechanical nakho kungase kuholele ekuhlulekeni kwezimoto ezimweni ezimbi kakhulu.Uma izinga lokushisa le-ambient liphezulu, injini ishoda ngesiphephetha-moya, ifeni ayiphelele, noma ikhava yabalandeli ishoda.Kulokhu, ukupholisa okuphoqelekile kufanele kuqinisekiswe ukuze kuqinisekiswe ukungena komoya noma ukushintshwa kwama-fan blades, ngaphandle kwalokho ukusebenza okuvamile 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, singagwema ukuchezuka, songe isikhathi, sixazulule inkinga ngokushesha okukhulu, futhi sigcine injini isesimweni esivamile sokusebenza.Ukuze kuqinisekiswe ukukhiqizwa okuvamile kwe-workshop.
