1.Indima yokudipha ipeyinti

1. Ukuphucula umsebenzi wobungqina bokufuma kwe-motor windings.

Kwi-winding, kukho i-pores eninzi kwi-slot insulation, i-interlayer insulation, i-insulation yesigaba, iingcingo zokubopha, njl.Kulula ukuthabatha umswakama emoyeni kunye nokunciphisa ukusebenza kwayo. Emva kokudipha kunye nokomisa, i-motor izaliswe ngepeyinti yokugquma kwaye yenza ifilimu yepeyinti egudileyo, eyenza kube nzima ukuba ukufuma kunye neegesi ezidliwayo zihlasele, ngaloo ndlela ziphucula iimpawu zobungqina bokufuma kunye ne-corrosion-resistant of the winding.

2.Ukwandisa amandla okugquma umbane wokujija.

Emva kokuba i-windings ifakwe kwipeyinti kwaye yomisiwe, ukujika kwabo, iikhoyili, izigaba kunye nezixhobo ezahlukeneyo zokukhusela zizaliswe ngepeyinti yokukhusela kunye neempawu ezintle ze-dielectric, okwenza amandla okudibanisa ama-windings aphezulu kakhulu kunangaphambi kokucwiliswa kwepeyinti.

I-3.Iimeko eziphuculweyo zokutshatyalaliswa kobushushu kunye nokuphuculwa kwe-thermal conductivity.

Ukunyuka kweqondo lokushisa kwemoto ngexesha lokusebenza kwexesha elide lichaphazela ngqo ubomi bayo benkonzo. Ubushushu be-winding bugqithiselwa kwi-heat sink ngokusebenzisa i-slot insulation. Izikhewu ezinkulu phakathi kwephepha lokugquma ucingo phambi kokuba ivarnishing ayihambelani nokuqhuba ubushushu kwi-winding. Emva kokugcoba kunye nokomisa, ezi zikhewu zizaliswe nge-varnish ye-insulating. I-thermal conductivity ye-insulating varnish ingcono kakhulu kunomoya, ngaloo ndlela iphucula kakhulu iimeko zokutshatyalaliswa kobushushu bomoya.

2.Iintlobo zevanishi yokugquma

Kukho iintlobo ezininzi zepeyinti yokugquma, ezifana ne-epoxy polyester, i-polyurethane, kunye ne-polyimide. Ngokuqhelekileyo, ipeyinti ehambelanayo yokukhusela ikhethwa ngokuhambelana nenqanaba lokumelana nobushushu, njenge-162 epoxy ester ebomvu yomgangatho we-enamel B (i-130 degrees), i-9129 epoxy i-solvent-free topcoat F (i-155 degrees ye-polysterified, i-197 degree ye-polysterified, i-197 i-modsterified, i-197 degrees high quality), imeko yokuba ipeyinti yokugquma idibana nemfuno yokumelana nobushushu, kufuneka ikhethwe ngokwendawo apho imotor ikhona, njenge-thermal conductivity, ukumelana nokufuma, njl.

3.Iintlobo ezintlanu zeenkqubo zokuvanisha

1.Ukugalela

Xa ulungisa i-motor enye, i-varnishing ejikelezayo inokuqhutywa yinkqubo yokugalela.Xa ugalela, beka i-stator ngokuthe nkqo kwi-tray evuzayo yepeyinti kunye nesiphelo esinye sokujikeleza sijonge phezulu, kwaye usebenzise ipeyinti yepeyinti okanye ibrashi yepeyinti ukuze ugalele ipeyinti kwindawo ephezulu. igalelwe ngokupheleleyo.

2.Idrip leaching

Le ndlela ifanelekile kwi-varnishing yeenjini zombane ezincinci kunye neziphakathi.

①Ifomula. I-6101 epoxy resin (i-mass ratio), i-50% ye-tung yeoli i-anhydride ye-maleic, ilungele ukusetyenziswa.

②Preheating: Fudumeza i-winding malunga nemizuzu ye-4, kwaye ulawule ubushushu phakathi kwe-100 kunye ne-115 ° C (ilinganiswe nge-thermometer yendawo), okanye ubeke i-winging kwisithando somisa kwaye ushushu malunga neeyure ze-0.5.

③Ukuthontsiza. Beka isitator semoto ngokuthe nkqo kwitreyi yepeyinti, kwaye uqalise ukuthontsiza ipeyinti ngesandla xa ubushushu bemoto busihla ukuya kwi-60-70 ℃. Emva kwemizuzu eyi-10, vula i-stator kwaye ucofe ipeyinti kwelinye isiphelo somoya de ifakwe ngokupheleleyo.

④Ukunyanga. Emva kokuvuthwa, ukuvuthwa kunikwe amandla okuphilisa, kwaye ubushushu bomoya bugcinwa kwi-100-150 ° C; Ixabiso lokumelana nokufakwa kwe-insulation lilinganiswa lide lifaneleke (20MΩ), okanye i-winging ifakwe kwisithando somiso sokufudumeza kwiqondo lokushisa elifanayo malunga neeyure ezingama-2 (kuxhomekeke kubukhulu bemoto), kwaye ikhutshwe kwi-oven xa ukuxhatshazwa kwe-insulation kudlula i-1.5MΩ.

3.Ipeyinti yerola

Le ndlela ifanelekile kwi-varnishing yeenjini ezinobungakanani obuphakathi. Xa uguqa ipeyinti, uthele ipeyinti yokukhusela kwi-tank yepeyinti, ubeke i-rotor kwi-tank yepeyinti, kwaye umphezulu wepeyinti kufuneka ucwilise i-rotor winding ngaphezu kwe-200mm. Ukuba itanki yepeyinti iphantsi kakhulu kwaye indawo ye-rotor winding efakwe kwipeyinti incinci, i-rotor kufuneka iguqulwe ngamaxesha amaninzi, okanye ipeyinti kufuneka isetyenziswe ngebrashi ngelixa i-rotor iqengqeleka. Ngokuqhelekileyo ukuqengqeleka kwamaxesha ama-3 ukuya kuma-5 kunokwenza ipeyinti yokugquma ingene kwindawo yokugquma.

4.Ukuntywiliselwa

Xa kulungiswa iinjini ezincinci kunye neziphakathi kwiibhetshi, i-windings inokucwiliswa kwipeyinti. Xa untywiliselwa, qala ubeke ubungakanani obufanelekileyo bepeyinti yokugquma kwitoti yepeyinti, emva koko uxhome i-motor stator, ukuze ulwelo lwepeyinti luntywilisele kwi-stator ngaphezulu kwe-200mm. Xa i-liquid yepeyinti ingena kuzo zonke izikhewu phakathi kwee-windings kunye nephepha le-insulating, i-stator iphakanyiswe kwaye ipeyinti ikhutshwe. Ukuba i-0.3 ~ 0.5MPa uxinzelelo longezwa ngexesha lokucwiliswa, umphumo uya kuba ngcono.

5.Ukuntywiliselwa koxinzelelo lwevacuum

I-windings of high-voltage motors kunye ne-motor encinci kunye ne-medium-size-motor ezineemfuno zomgangatho ophezulu wokugquma zinokuthi zibe phantsi koxinzelelo lwe-vacuum dipping. Ngexesha lokuntywila, i-stator yemoto ifakwe kwisitya sepeyinti esivaliweyo kwaye umswakama uyasuswa kusetyenziswa itekhnoloji ye-vacuum. Emva kokuba i-windings ifakwe kwipeyinti, uxinzelelo lwe-200 ukuya kwi-700 kPa lusetyenziswe kwindawo yepeyinti ukuvumela ulwelo lwepeyinti ukuba lungene kuzo zonke izikhewu kwi-windings kunye nzulu kwi-pores yephepha le-insulating ukuqinisekisa umgangatho wokudibanisa.
