Esinye sezimo ezesatshwa kakhulu ekulungiseni iphutha kwe-electromechanical ukushiswa kwemoto. Uma umjikelezo kagesi noma ukwehluleka komshini kwenzeka, injini izosha uma unganakile lapho uhlola umshini. Kulabo abangenalwazi, ingasaphathwa Indlela yokukhathazeka, ngakho-ke kuyadingeka ukuqonda ngokugcwele imithethonqubo ngenani lezimoto eziqala kanye nesikhathi sokuphumula, kanye nolwazi oluhlobene nemoto.

Imithetho yenombolo yemoto eqalayo kanye nesikhathi sokuphumula

a.Ngaphansi kwezimo ezijwayelekile, i-squirrel-cage motor ivunyelwe ukuqala kabili esimweni esibandayo, futhi isikhawu phakathi kwesikhathi ngasinye akufanele sibe ngaphansi kwemizuzu emi-5. Esimweni esishisayo, kuvunyelwe ukuqala kanye; kungakhathaliseki ukuthi kubanda noma kushisa, i-motor iqala Ngemva kokuhluleka, isizathu kufanele sitholakale ukuze sinqume ukuthi sizoqala ngokuzayo.

b.Uma kwenzeka ingozi (ukuze ugweme ukuvala, ukhawule umthwalo noma ubangele ukulimala kwemishini eyinhloko), inombolo yokuqala yemoto ingaqalwa kabili ngokulandelana kungakhathaliseki ukuthi kushisa noma kubanda; kumamotho angaphansi kuka-40kW, inani leziqalo alinqunyelwe.

c.Ngaphansi kwezimo ezijwayelekile, imvamisa yokuqala ye-DC motor akufanele ibe kaningi kakhulu. Ngesikhathi sokuhlolwa kwengcindezi kawoyela ephansi, isikhawu sokuqala akufanele sibe ngaphansi kwemizuzu eyi-10.

d.Uma kwenzeka ingozi, inani lokuqala kanye nesikhathi sokuphumula semoto ye-DC akunqunyelwe.

e.Lapho injini (kuhlanganise ne-DC motor) yenza ukuhlolwa kwebhalansi okuguquguqukayo, isikhawu sesikhathi sokuqala yilesi:

(1). Amamotho angaphansi kuka-200kW (wonke amamotha angu-380V, angu-220V DC), isikhawu sesikhathi amahora angu-0.5.

(2). Injini engu-200-500kW, isikhawu sehora ihora elingu-1.

Kufaka phakathi: iphampu ye-condensate, iphampu yokuphakamisa i-condensate, iphampu yangaphambili, iphampu yokuphakela amanzi ebhange, iphampu yokuhambisa isithando somlilo, #3 ibhande elihambisa ibhande, #6 ibhande lokuhambisa.

(3). Ezinjinini ezingaphezu kuka-500kW, isikhawu sesikhathi amahora ama-2.

Kubandakanya: iphampu kagesi, i-crusher yamalahle, isigayo samalahle, isivuthelo, isiphephetha-moya esiyinhloko, isiphephetha-moya sokumunca, iphampu yokujikeleza, iphampu yokushisisa yenethiwekhi.

Imithetho yezwe ebandayo neshisayo

a.Umehluko phakathi kwengqikithi noma izinga lokushisa lekhoyili lemoto kanye nezinga lokushisa elizungezile lingaphezu kwama-degree angu-3, ​​okuyisimo esishisayo; umehluko wokushisa ungaphansi kwama-degree angu-3, ​​okuyisimo esibandayo.

b.Uma kungekho ukuqapha imitha, izinga liwukuthi injini ivaliwe yini amahora angu-4. Uma idlula amahora angu-4, kubanda, futhi uma ingaphansi kwamahora angu-4, kuyashisa.

Ngemuva kokuthi i-motor isishintshiwe noma lapho injini isanda kuqaliswa ukusebenza okokuqala, isikhathi sokuqala kanye nokungalayishwa kwamanje kwenjini kufanele kurekhodwe.

Ngemuva kokuthi injini iqale, uma inyakaza ngenxa yezizathu ezinjengokuhlangana noma ukuvikela, imbangela kufanele ibhekwe ngokucophelela futhi kubhekwane nayo. Kunqatshelwe ngokuphelele ukuqala futhi ngezizathu ezingaziwa.

Ukuqapha nokusebenza kwezimoto:

Lapho injini isebenza, izisebenzi ezisemsebenzini kufanele zihlole njalo futhi zilungiswe, okuhlanganisa:

1 Hlola ukuthi ingabe i-voltage yamanje kanye ne-voltage yemoto iyalidlula inani elivumelekile, nokuthi uguquko lujwayelekile yini.

2 Umsindo wengxenye ngayinye yemoto uvamile ngaphandle komsindo ongajwayelekile.

3 Izinga lokushisa lengxenye ngayinye yemoto livamile futhi alidluli inani elivumelekile.

4 Ukudlidliza kwezimoto kanye nokunyakaza kochungechunge lwe-axial akudluli inani elivumelekile.

5 Izinga lamafutha kanye nombala wezimoto ezithwalayo kanye nezihlahla ezithwalayo kufanele kube okujwayelekile, futhi indandatho yamafutha kufanele ijikelezwe kahle ngamafutha, futhi akukho ukuvuza kwamafutha noma ukuphonsa amafutha okufanele kuvunyelwe.

6 Intambo yaphansi ye-motor casing iqinile, futhi isivikelo nesembozo sokuzivikela aziguquki.

7. Ikhebula alishisi ngokweqile, futhi isixhumi nomshuwalense akushisi ngokweqile.I-cable sheath kufanele isekelwe kahle.

8Ikhava yokuvikela yefeni yokupholisa injini igoqwe ngokuqinile, futhi i-impeller ayiyithinti ikhava yangaphandle.

9 Ingilazi ye-peephole ye-motor iphelele, ngaphandle kwamaconsi amanzi, ukunikezwa kwamanzi kwe-cooler kuyinto evamile, futhi igumbi lomoya kufanele lome futhi lingabi namanzi.

10 Injini ayinalo iphunga lokusha elingavamile kanye nentuthu.

11 Zonke izinkomba zesignali, amathuluzi, isilawuli semoto kanye namadivayisi okuvikela ahlobene nemoto kufanele aphelele futhi abe sesimweni esihle.

Kuma-motor e-DC, kufanele kubhekwe ukuthi amabhulashi axhumene kahle nendandatho ye-slip, akukho mlilo, ukugxuma, ukugxuma kanye nokugqoka okunzima, ubuso bendandatho ye-slip buhlanzekile futhi bushelelezi, akukho ukushisa nokugqoka, ukungezwani kwentwasahlobo kujwayelekile, futhi ubude be-carbon brush abukho ngaphansi kuka-5mm.

Ama-bearings enjini kanye nokuhlolwa kwemoto kwangaphandle kungumsebenzi wabasebenzi abafanelekile abasemsebenzini.

Amafutha okugcoba noma amafutha asetshenziselwa ama-motor bearings kufanele ahlangabezane nezidingo zokushisa zokusebenza kwama-bearings, futhi izinto zokugcoba ezisetshenzisiwe kufanele zishintshwe njalo ngokuvumelana nezidingo zokusetshenziswa.

Ukukala umsebenzi wokufakelwa kwenjini, ngemuva kokuxhumana nokuthola imvume, okokusebenza kuzocishwa futhi ukukala kuzokwenziwa. Okokusebenza okuhlulekayo ukukala ukufakwa, kufanele kufakwe encwadini yokurekhoda kusenesikhathi, futhi kubikwe, futhi kuphume ekusebenzeni.

Uma injini ingasebenzi ngendlela evamile noma idinga ukushintsha indlela yokusebenza kwayo, kufanele ithintwe nenduna noma umuntu ophethe umthwalo wemfanelo ukuze avume.
