I-varnish ye-Impregnation isetshenziselwa ukufaka amakhoyili kagesi nama-windings ukuze kugcwalise izikhala kuwo, ukuze izintambo zamakhoyili nezintambo nezinye izinto zokuvikela zihlanganiswe ndawonye ukuze kuthuthukiswe amandla kagesi, izakhiwo zemishini, ukuqhutshwa kwe-thermal kanye nezakhiwo zokuvikela zikagesi. i-coil insulation. UNksz Can uzoba nengxoxo emfushane nawe mayelana ne-varnish yokumilisela namuhla, enethemba lokusiza ngokulawula ikhwalithi yokucubungula.
1 Izidingo eziyisisekelo zekhoyili kagesi yokufaka ivarnish
● I-viscosity ephansi kanye nokuqukethwe okuqinile okuphezulu ukuze kuqinisekiswe ukungena kahle kanye nenani lokulenga upende;
● Ukuzinza okuhle ngesikhathi sokugcinwa nokusetshenziswa;
● Izici ezinhle zokuphulukisa nokomisa, ukuphulukiswa ngokushesha, izinga lokushisa eliphansi, ukomisa okuhle kwangaphakathi;
● Amandla okubopha okuphezulu, ukuze okokusebenza kukagesi kukwazi ukumelana nesivinini esiphezulu nomthelela wamandla emishini;
● Ihambisana nezinye izingxenye;
● Ukusebenza kahle kwemvelo.
2 Ukuhlukaniswa nezici ze-varnish yokufaka
● I-varnish yokumilisela encibilikayo. I-varnish ye-solvent impregnation iqukethe i-solvent, futhi okuqukethwe kwayo okuqinile (ingxenye enkulu) kuvame ukuba phakathi kuka-40% no-70%. Ivashi yokumilisela encibilikisiwe enokuqukethwe okuqinile okukhulu kuno-70% ibizwa ngokuthi ivashi yokumilisela encibilika kancane, ebizwa nangokuthi ivanisha yokufaka eqinile eqinile.
I-solvent impregnation varnish inokuqina okuhle kwesitoreji, i-permeability enhle kanye nezakhiwo zefilimu, futhi ishibhile, kodwa isikhathi sokucwilisa nokubhaka side, futhi i-solvent esele izobangela izikhala ezintweni ezifakiwe. I-solvent eguquguqukayo nayo ibangela ukungcoliswa kwemvelo kanye nemfucuza, futhi ukusetshenziswa kwayo kulinganiselwe. Ngokuyinhloko isetshenziselwa ukukhulelwa kweama-motor ane-voltage ephansinamawindi kagesi.
Ivashi yokumilisela engancibilikiyo ivamise ukucwiliswa ngokucwiliswa, futhi ukufakwa kwe-vacuum pressure nokuconsa nakho kungasetshenziswa.
Ivashi yokumilisela engancibilikiyo iyelapheka ngokushesha, inesikhathi esifushane sokucwilisa kanye nesikhathi sokubhaka, ayinasikhala somoya endaweni efakwa ngaphakathi, inobuqotho obuhle, futhi inezinto eziphakeme zikagesi nezomshini. Ivashi yokumilisela engancibilikiyo ithuthukiswe kabanzi futhi yasetshenziswa ukuze ithathele indawo yokuvanisha yokufakelwa engancibiliki kumajeneretha anamandla kagesi, amamotho, imigqa yokukhiqiza emikhulu, ebhithi ngokushesha, kanye nezinjini ezithile ezikhethekile nezinto zikagesi. Kodwa-ke, isikhathi sokugcina se-varnish engena-solvent-free impregnation sifushane. I-varnish ye-solvent-free impregnation ingafakwa ngokucwiliswa, ukucwiliswa okuqhubekayo, ukucwiliswa okugoqayo, ukucwiliswa okuconsayo kanye nokucwiliswa kwe-vacuum pressure.
Izinyathelo ezi-3 zokusebenzisa i-varnish yokufaka i-impregnation
● Ukuphathwa kwekhwalithi ye-varnish yokufakelwa ngesikhathi sokusetshenziswa. Upende ongancibilikiyo uwukwakheka kwe-polymerizable resin. Izinhlobo ezahlukahlukene zopende wokumilisa ongancibilikiyo zizozinza zibe ngamadigri ahlukahlukene ngesikhathi sokugcinwa kanye nokusetshenziswa. Ukuphatha okungalungile kuzosheshisa le-self-polymerization. Uma upende ongancibiliki emshinini wokufakelwa ukhiqiza ijeli, uzoqina ngokushesha futhi ulahlwe phakathi kwezinsuku ezingu-1 kuya kwezingu-2, okubangela izingozi ezinkulu nokulahlekelwa. Ngakho-ke, ikhwalithi yopende wokufaka i-solvent-free osetshenziswayo kufanele ilawulwe ngokuqinile, futhi izinyathelo kufanele zithathwe ukuze kuqinisekiswe ukuzinza kwekhwalithi yepende.
(1) Njalo landelela futhi uqaphe ikhwalithi kapende okhulelwe osetshenziswayo. Izinto zokuhlola nemijikelezo yokuhlola zingakhiwa ngokuya ngopende okhulelwe osetshenzisiwe, imishini yenqubo yokumithisa kanye nemisebenzi yokukhiqiza. Izinto zokuhlola ngokuvamile zihlanganisa ukuminyana, ukuminyana, isikhathi sejeli, umswakama kanye ne-diluent esebenzayo. Uma inkomba yekhwalithi kapende idlula umkhawulo ophezulu wenkomba yokulawula kwangaphakathi, upende omusha noma ezinye izinyathelo kufanele zithathwe ngokushesha ukuze zilungiswe.
(2) Vimbela umswakama nokunye ukungcola ekungeneni kupende owumithisayo. Ukuthi i-epoxy noma i-polyester yokumilisela upende ongancibilikiyo izwela kakhulu kumswakama. Inani elincane lomswakama ongena ohlelweni lizokwenza ukuthi i-viscosity kapende ikhuphuke ngokushesha. Umswakama nokungcola kufanele kuvinjelwe ukungena kupende ngesikhathi sokuthutha, ukugcinwa kanye nokusetshenziswa kopende okhulelwe. Amanzi, umoya kanye nezivunguvungu zamangqamuzana aphansi ezixutshwe kupende zingasuswa ngokucofa kanye nemishini yokususa upende ungqimba wokupenda, futhi uketshezi lukapende lungahlungwa ngemishini yokuhlunga. I-sediment kupende ihlungwa njalo ukuze kugcinwe inhlaka ihlanzekile.
(3) Khetha kahle izinga lokushisa lokukhulelwa ukuze i-viscosity kapende ifinyelele inani elishiwo. Lokhu kungakhethwa ngokusekelwe ejikeni le-viscosity-temperature likapende, kuyilapho kucatshangelwa umehluko phakathi kwezinto zokusebenza ze-cold-dip kanye ne-hot-dip workpieces. Uma izinga lokushisa lokucwilisa liphezulu kakhulu, lizoba nomthelela omubi ekuzinzeni kwe-viscosity kapende; uma izinga lokushisa lokucwilisa liphansi kakhulu, i-viscosity izoba phezulu futhi umphumela wokucwilisa uzoba mubi.
(4) Njalo zungeza futhi ugovuze uketshezi lukapende ukuze ugcine izinga lokushisa loketshezi lukapende ethangini likapende nepayipi liphansi ngangokunokwenzeka ukuze uvimbele uketshezi lukapende olusepayipini ukuthi lingazikhukhumezi futhi liqine, okuzovimba ipayipi likapende.
(5) Faka njalo upende omusha. Umjikelezo wokwengeza kanye nenani kuncike emsebenzini wokukhiqiza kanye nemvelo kapende. Ngokungeza upende omusha ngaphansi kwemisebenzi evamile yokukhiqiza, upende wokufaka ethangini ngokuvamile ungasetshenziswa ngokuzinza isikhathi eside.
(6) Ukugcinwa kwezinga lokushisa eliphansi kunciphisa isivinini sokuzinza kwe-polymerization kapende. Izinga lokushisa lokugcina lingalawulwa libe ngaphansi kuka-10°C. Ezikhathini ezingasetshenziswa isikhathi eside noma ezinemibandela, izinga lokushisa lokugcina kufanele libe ngaphansi ngisho nangaphezulu, njenge -5°C.
Ngopende we-solvent impregnation, okugxilwe kukho ukuhlola njalo ukuminyana kanye ne-viscosity kapende ukuze uwugcine ngaphakathi kwebanga lokulawula.
● Umthelela wokungcola ekwelapheni upende wokufakwa kwe-polyester ongagcwalisiwe. Ukuzijwayeza kubonise ukuthi izinto ezifana nethusi nama-phenol zinomphumela wokulibaziseka ekwelapheni upende wokufakwa kwe-polyester ongagcwele. Ezinye izinto ezisetshenziswayo, njengerabha kanye nocingo olunamanzi olunamafutha, zizoncibilika noma zivuvuke i-styrene monomer esebenzayo kupende wokufakelwa, kwenze ingaphezulu lesiqephu sokusebenza esifakwe ngaphakathi sinamathele.
● Izinkinga zokuhambisana. Ukuhlolwa kokuhambisana kufanele kwenziwe ukuze kuqinisekiswe ukuthi upende wokufakelwa uhambisana ngokugcwele nezinye izinto ezikhona ohlelweni lokufakelwa.
●Izinkinga zenqubo yokubhaka. I-solvent-based impregnation varnishes iqukethe inani elikhulu lama-solvents. Ngokuvamile, ukufakwa kokubili noma ngaphezulu, ukubhaka kanye nokwanda kwezinga lokushisa kancane kancane izinqubo zokubhaka zisetshenziselwa ukuvimbela izimbobo noma izikhala efilimini kapende futhi kuthuthukiswe ukusebenza nempilo yokufakwa kwamakhoyili. Inqubo yokubhaka yama-varnish e-solvent-free impregnation kufanele iqaphele ukuvimbela ukugeleza kweglue ngokweqile. Ukubhaka okujikelezayo kunganciphisa ngempumelelo ukugeleza kweglue.
●Izindaba zokunukubezeka kwemvelo. Izinyathelo ezifanele kufanele zithathwe ukuze kulawulwe umhwamuko we-solvent kanye ne-styrene ekhishwa ngesikhathi sokumilisa kanye nenqubo yokubhaka ngaphakathi kwebanga lokuqukethwe elishiwo elivumelekile.
