3.Five iri matakai na varnishing

1.Zubawa

Lokacin da ake gyara injin guda ɗaya, ana iya yin amfani da varnishing ta hanyar zubar da ruwa. Lokacin da ake zubowa, sanya stator a tsaye a kan tiren ɗigon fenti tare da ɗaya ƙarshen juyawa yana fuskantar sama, kuma yi amfani da tukunyar fenti ko goge fenti don zuba fenti a saman ƙarshen iska. zuba.

2.Drip leaching

Wannan hanya ta dace da varnishing na kananan da matsakaici-sized lantarki Motors.

① Formula. 6101 epoxy resin (mass rabo), 50% tung man maleic anhydride, shirye don amfani.

② Preheating: Zazzage iska na kusan mintuna 4, kuma sarrafa zafin jiki tsakanin 100 zuwa 115 ° C (ana auna shi da ma'aunin zafi da sanyio), ko sanya iskar a cikin tanderun bushewa sannan a zafi shi na kusan awanni 0.5.

③ Ruwa. Sanya stator na motar a tsaye akan tiren fenti, kuma fara ɗigon fenti da hannu lokacin da zafin jikin motar ya faɗi zuwa 60-70 ℃. Bayan mintuna 10, juya stator kuma ɗigo fenti a ɗayan ƙarshen iskar har sai an jiƙa sosai.

④ Magani. Bayan drip, iskar tana da kuzari don warkewa, kuma ana kiyaye yawan zafin jiki a 100-150 ° C; Ana auna ƙimar juriya na insulation har sai ya cancanta (20MΩ), ko kuma sanya iska a cikin tanderun bushewa don dumama a cikin zafin jiki guda na kimanin sa'o'i 2 (dangane da girman motar), kuma ana fitar da shi daga cikin tanda lokacin da juriya na rufi ya wuce 1.5MΩ.

3.Roller fenti

Wannan hanya ta dace da varnishing na matsakaici-sized Motors. Lokacin mirgina fenti, zuba fenti mai rufewa a cikin tankin fenti, sanya rotor a cikin tankin fenti, kuma saman fenti ya kamata ya nutsar da juzu'in jujjuyawar sama da 200mm. Idan tankin fenti ya yi zurfi sosai kuma yankin na rotor da aka nutsar da shi a cikin fenti kadan ne, ya kamata a jujjuya na'urar sau da yawa, ko kuma a yi amfani da fenti da goga yayin da ake birgima. Yawancin lokaci mirgina sau 3 zuwa 5 na iya sa fenti mai rufewa ya shiga cikin rufin.

4. nutsewa

Lokacin gyaran ƙananan motoci masu girma da matsakaici a cikin batches, ana iya nutsar da iska a cikin fenti. Lokacin nutsewa, da farko sanya adadin da ya dace na fenti a cikin fenti, sannan a rataya stator a ciki, ta yadda ruwan fenti ya nutsar da stator da fiye da 200mm. Lokacin da ruwan fenti ya shiga duk gibin da ke tsakanin iska da takarda mai rufewa, ana ɗaga stator sama kuma fenti ya ɗigo. Idan an ƙara matsa lamba 0.3 ~ 0.5MPa a lokacin nutsewa, sakamakon zai zama mafi kyau.

5.Vacuum matsa lamba nutsewa

Ana iya shigar da iskar manyan injuna masu ƙarfin lantarki da ƙanana da matsakaita masu girma dabam tare da manyan buƙatun ingantattun injuna don tsomawa matsa lamba. A lokacin tsomawa, ana sanya stator na motar a cikin rufaffiyar kwandon fenti kuma ana cire danshi ta amfani da fasahar injin. Bayan da aka tsoma iska a cikin fenti, ana amfani da matsa lamba na 200 zuwa 700 kPa a kan fuskar fenti don ba da damar ruwan fenti ya shiga cikin dukkan ramukan da ke cikin windings da zurfi a cikin ramukan takarda mai rufi don tabbatar da ingancin tsomawa.
