Izizathu zokushiswa kwezimoto

Izizathu zokushiswa kwezimoto zingahlukaniswa zibe: umthwalo, ukunikezwa kwamandla, ukufakwa kwezimoto,isigaba esizenzakalelayo

1.Isigaba esizenzakalelayo

Isizathu:Ngokuvamile ngenxa yokuntuleka kwamandla esigaba.(isigaba esingu-1 esinganikeziwe noma i-voltage yokuhlinzeka enganele).Noma indawo yokuxhumana yocingo kulayini ayivaliwe.Iphoyinti lokuxhuma ucingo liyanqamula, liyaxegisa noma indawo yokuxhumana ikhipha izimbangela nokunye.

Isici:Isigaba esisodwa noma ezimbili (izinga lesi-4) kuma-windings wonke amnyama, ikhoyili yonakaliswa ngokulinganayo.

2.Ukulayisha ngokweqile

Isizathu:Ngokuvamile kuthatha isikhathi eside ukugijima phezu kwamanje, ukushisa ngokweqile, ukuqala noma ukubhuleka njalo,izintambo iphutha.

Isici:Ukusonteka konke kuba mnyama, ukubopha ekugcineni kuba nombala futhi kuba brittle noma kuphuke.

3.Ukuhlukana

Isizathu:Intambo ene-enameled inqamuka ohlelweni lokukhiqiza izinjini, futhi amanzi, i-asidi, nezinye izinto ezonakalisayo ohlelweni nakho kungabangela ukwehluleka okunjalo.

Isici:Amajika ashiswe kancane, ngokuvamile imbobo yemoto ihlanzekile, kunephuzu elilodwa kuphela eliqhumayo.

4.Electrode izigaba ezimbili

Isizathu:Iphepha le-interphase alikho endaweni, noma iphepha le-interphase (i-casing) liphukile.

Isici:Injini iyasha phakathi kwezigaba ezimbili.

5.Shaya

Isizathu:Ibanga elinganele phakathi kwekhoyili nesihlalo sekhava yokugcina.

Isici:Kukhona amabala okusha ezinhlangothini zombili phakathi kwekhoyili nesembozo sokugcina.

Indlela yokuvimbela injini ukuthi ingashi?

1.Gcina injini ihlanzekile

Injini kufanele ngaso sonke isikhathi igcine i-airlet ihlanzekile ngesikhathi sokusebenza.

Uma uthuli, uwoyela namanzi kudonselwa kumotor, kwakheka i-short circuit medium ukuze kulimaze ukufakwa kocingo.

Ibangela i-interturn short circuit, ukwanda kwamanje, izinga lokushisa liyakhuphuka, lishise imoto.

2.Sebenza ngaphansi komthwalo olinganiselwe

Ukusebenza kokulayisha ngokweqile kwezimoto, isizathu esiyinhloko ukuthi umthwalo wokudonsa mkhulu kakhulu, i-voltage iphansi kakhulu, noma imishini eshayelwa ibambekile.

Lapho i-motor ihamba esimweni sokugcwala ngokweqile, isivinini semoto siyehla, ukwanda kwamanje, izinga lokushisa liyakhuphuka futhi ikhoyili ishisa kakhulu. , okuyisizathu esiyinhloko sokuthi injini ishe.

3.Gcina izinga lamanje lezigaba ezintathu liqinile

Kumamotor e-asynchronous ezigaba ezintathu, umehluko phakathi kwenani elimaphakathi lanoma yisiphi isigaba samanje samanje kanye nelesinye isigaba samanje sezigaba ezimbili akuvunyelwe ukudlula u-10% ukuze kuqinisekiswe ukusebenza okuphephile nokujwayelekile kwenjini.

Uma inani elilinganiselwe le-single-phase current kanye nenani elilinganiselwe lezinye izigaba ezimbili zamanje lidlula umkhawulo onqunyiwe, libonisa ukuthi imoto inephutha.Isizathu kufanele sitholakale futhi iphutha lingasuswa ngaphambi kokuba injini iqhubeke nokusebenza, ngaphandle kwalokho injini izosha.

4.Gcina izinga lokushisa elijwayelekile

Izinga lokushisa le-bearing, i-stator, i-enclosure nezinye izingxenye ze-motor kufanele zihlolwe njalo ukuze kuhlolwe izinto ezididayo, ikakhulukazi injini engenawo amandla kagesi, izikhungo zokuqapha zamanje kanye nemvamisa kanye nezindawo zokuvikela ukulayisha ngokweqile, futhi ukuqapha ukukhuphuka kwezinga lokushisa kubaluleke kakhulu.

Uma izinga lokushisa likhuphuka eduze ne-bearing litholakala liphezulu kakhulu, kufanele limiswe ngokushesha ukuze kuhlolwe ukuthi ukuthwala konakalisiwe noma kufushane amafutha.Uma ama-bearings wonakalisiwe, kufanele ashintshwe ngama-bearings amasha ngaphambi kokusebenza.Uma ama-bearings eshoda ngamafutha, amafutha kufanele afakwe;uma kungenjalo, ama-bearings azophinde alimale, okuholela ekuweni, okuzobhubhisa i-motor ngokushanela.

5.Qaphela ukudlidliza, umsindo, nephunga

Uma i-motor idlidliza, izokwenza ukuthi i-non-coaxiality ye-motor exhunywe nayo ikhule, okuzokwandisa umthwalo wemoto, kwandise okwamanje, futhi kwandise izinga lokushisa futhi kushise imoto.

Ngakho-ke, lapho i-motor isebenza, kuyadingeka ukuhlola njalo ukuthi ama-anchor bolts, isembozo sokugcina se-motor kanye nekhava ye-bearing pressure ayikhululekile, nokuthi ngabe idivayisi yokuxhuma ithembekile yini.Uma kukhona inkinga etholakalayo, kufanele ixazululwe ngesikhathi.

6.Qinisekisa ukusebenza okuvamile kwempahla yokuqala

Ukugcinwa okuyinhloko kwe-starter ukuhlanza nokuqiniswa.Uma ukuxhumana kwe-contactor kungahlanzekile, ukumelana nokuxhumana kuzokwandiswa, okuholela ekushiseni othintana naye, okubangela ukuntuleka kwesigaba nokushiswa kwe-motor.I-rust corrosion kanye nothuli. ukuqoqwa komgogodla wekhoyili kazibuthe yesixhumi esithintayo kuzokwenza ikhoyili ingavali ngokuqinile futhi ikhiphe umsindo onamandla, kwandise ikhoyili yamanje, kushise ikhoyili futhi kubangele amaphutha.

Izinto zokulawula ugesi kufanele zibe endaweni eyomile, engena umoya futhi kube lula ukuyisebenzisa. Susa uthuli njalo, qinisa zonke izikulufu zezintambo, hlola ukuthi ukuthintana kwe-contactor kuhle futhi kuthembekile, nokuthi izingxenye eziwumshini ziyazwela futhi zinembile yini.Gcina injini isesimweni esihle sobuchwepheshe. , ukuze injini iqale kahle ngaphandle kokuvutha.
