Impregnation varnish ntchito impregnate magetsi koyilo ndi windings kudzaza mipata mmenemo, kotero kuti mawaya koyilo ndi mawaya ndi zipangizo zina zoteteza ndi womangidwa pamodzi kupititsa patsogolo mphamvu zamagetsi, mawotchi katundu, matenthedwe madutsidwe ndi zoteteza katundu wa magetsi. kutsekereza koyilo. Mayi Can adzakhala ndi kukambirana mwachidule ndi inu za varnish ya impregnation lero, ndikuyembekeza kuthandizira ndondomeko ya khalidwe labwino.
1 Zofunikira pazamagetsi za coil impregnation varnish
● Low mamasukidwe akayendedwe ndi mkulu olimba okhutira kuonetsetsa permeability wabwino ndi penti kulendewera kuchuluka;
● Kukhazikika kwabwino panthawi yosungira ndikugwiritsa ntchito;
● Makhalidwe abwino ochiritsa ndi kuyanika, kuchira msanga, kutentha kochepa, kuyanika bwino kwamkati;
● Mphamvu zomangirira kwambiri, kuti zida zamagetsi zitha kupirira kuthamanga kwambiri komanso mphamvu yamakina;
● Yogwirizana ndi zigawo zina;
● Kuchita bwino kwa chilengedwe.
2 Gulu ndi mawonekedwe a varnish ya impregnation
● Vanishi wosungunulira. Vanishi yosungunulira imakhala ndi zosungunulira, ndipo zolimba zake (kachigawo kakang'ono) nthawi zambiri zimakhala pakati pa 40% ndi 70%. Vanishi yosungunuka yosungunulira yokhala ndi zolimba kuposa 70% imatchedwa vanishi yosungunuka yosungunuka, yomwe imatchedwanso vanishi yolimba kwambiri.
Vanishi yosungunulira yosungunulira imakhala ndi kukhazikika bwino kosungirako, kukwanira bwino komanso kupanga filimu, ndipo ndiyotsika mtengo, koma nthawi yothira ndi yophika ndi yayitali, ndipo chosungunulira chotsalira chidzapangitsa mipata muzinthu zomwe zimayikidwa. Zosungunulira zosasunthika zimabweretsanso kuwonongeka kwa chilengedwe ndi zinyalala, ndipo kugwiritsa ntchito kwake kumakhala kochepa. Iwo makamaka ntchito impregnation wama motors otsika-voltagendi ma windings amagetsi.
Vanishi wosungunulira wopanda zosungunulira nthawi zambiri amamizidwa ndi kumizidwa, ndipo kulowetsedwa kwa vacuum ndi kudontha kungagwiritsidwenso ntchito.
Vanishi wosungunulira wosasungunulira amachiritsa mwachangu, amakhala ndi nthawi yaying'ono yoviika ndi kuphika, alibe mpweya wotsekera m'malo otsekera, amakhala ndi kukhulupirika, komanso amakhala ndi mphamvu zamagetsi komanso zamakina. Vanishi wosungunulira wopanda zosungunulira walimbikitsidwa kwambiri ndikugwiritsidwa ntchito kuti alowe m'malo mwa ma jenereta othamanga kwambiri, ma mota, mizere yayikulu, yothamanga kwambiri, ndi ma mota ena apadera ndi zida zamagetsi. Komabe, nthawi yosungiramo varnish yosungunulira yopanda zosungunulira ndiyofupika. Valashi wosungunulira wopanda zosungunulira amatha kumizidwa ndi kumizidwa, kumizidwa mosalekeza, kumizidwa mozungulira, kumizidwa kodontha komanso kumiza mwamphamvu mu vacuum.
3 Kusamala pakugwiritsa ntchito varnish ya impregnation
● Kusamalira bwino kwa varnish ya impregnation panthawi yogwiritsira ntchito. Utoto wopanda zosungunulira ndi polymerizable resin resin. Mitundu yosiyanasiyana ya utoto wopanda zosungunulira imadzipangira yokha polima mosiyanasiyana panthawi yosungira ndikugwiritsa ntchito. Kuwongolera kosayenera kumathandizira izi kudzipangira polima. Utoto wopanda zosungunulira mu zida za impregnation umatulutsa gel, imakhazikika mwachangu ndikuchotsedwa mkati mwa masiku 1 mpaka 2, ndikuyambitsa ngozi zazikulu ndi kutayika. Chifukwa chake, mtundu wa utoto wopanda zosungunulira womwe umagwiritsidwa ntchito uyenera kuyang'aniridwa mosamalitsa, ndipo njira ziyenera kutengedwa kuti zitsimikizire kukhazikika kwa utoto.
(1) Nthawi zonse muziyang'anira ndi kuyang'anira mtundu wa utoto womwe ukugwiritsidwa ntchito. Zinthu zowunikira komanso zoyendera zitha kupangidwa molingana ndi utoto woyimbira womwe umagwiritsidwa ntchito, zida zoyimbira komanso ntchito zopanga. Zinthu zowunikira nthawi zambiri zimaphatikizapo kachulukidwe, kachulukidwe, nthawi ya gel, kuchuluka kwa chinyezi komanso zinthu zoziziritsa kukhosi. Ngati mtundu wa utoto umaposa malire apamwamba a index yowongolera mkati, utoto watsopano kapena njira zina ziyenera kuchitidwa nthawi yomweyo kuti zisinthe.
(2) Tetezani chinyezi ndi zonyansa zina kuti zisalowe mu utoto wopaka mimba. Kaya utoto wa epoxy kapena polyester wopanda zosungunulira umakhudzidwa kwambiri ndi chinyezi. Chinyezi chochepa cholowa m'dongosolo chidzachititsa kuti kukhuthala kwa utoto kukwezeke mofulumira. Chinyezi ndi zonyansa ziyenera kupewedwa kuti zisalowe mu utoto panthawi yoyendetsa, kusungirako ndi kugwiritsa ntchito utoto wothira mimba. Madzi, mpweya ndi ma cell otsika omwe amasakanikirana ndi utoto amatha kuchotsedwa ndi vacuuming ndi utoto wosanjikiza zida zochotsera gasi, ndipo utoto wamadzimadzi ukhoza kusefedwa ndi zida zosefera. Dothi la penti limasefedwa nthawi zonse kuti utomoni usungidwe bwino.
(3) Sankhani bwino kutentha kwa impregnation kotero kuti kukhuthala kwa utoto kufika pamtengo wotchulidwa. Izi zitha kusankhidwa potengera kupendekera kwamafuta akupendekera kwa utoto, poganizira kusiyana pakati pa zida zoziziritsa kuzizira ndi zogwirira ntchito zotentha. Ngati kutentha kwa dipping kuli kwakukulu kwambiri, kudzakhala ndi zotsatira zoipa pa kukhazikika kwa viscosity ya utoto; ngati kutentha koviika kuli kochepa kwambiri, kukhuthala kudzakhala kwakukulu ndipo zotsatira zoviika zidzakhala zoipa.
(4) Nthawi zonse muzizungulira ndi kusonkhezera madzi a penti kuti kutentha kwa madzi a penti mu thanki ya penti ndi payipi kuchepe kwambiri kuti madzi a penti a m’paipi asamadzigwetse ndi kulimba, zomwe zingatseke payipi ya utoto.
(5) Onjezani utoto watsopano nthawi zonse. Kuzungulira kowonjezera ndi kuchuluka zimadalira ntchito yopanga ndi mtundu wa utoto. Powonjezera utoto watsopano pansi pa ntchito zanthawi zonse zopanga, utoto wothira mu thanki utha kugwiritsidwa ntchito mokhazikika kwa nthawi yayitali.
(6) Kusungirako kutentha kochepa kumachepetsa kuthamanga kwapolymerization ya utoto. Kutentha kosungirako kumatha kuyendetsedwa pansi pa 10°C. Kwa nthawi yayitali yosagwiritsidwa ntchito kapena yokhazikika, kutentha kosungirako kuyenera kutsika kwambiri, monga -5°C.
Kwa utoto wosungunulira wosungunulira, cholinga chake ndikuwunika pafupipafupi kachulukidwe ndi kukhuthala kwa utoto kuti ukhale mkati mwaowongolera.
● Zotsatira za zonyansa pakuchiritsa kwa utoto wa polyester wosakanizidwa. Zochita zawonetsa kuti zinthu monga mkuwa ndi phenols zimachedwetsa kuchiritsa kwa utoto wopangidwa ndi polyester wopangidwa ndi unsaturated. Zida zina, monga mphira ndi waya wonyezimira wa enameled, zidzasungunuka kapena kutupa ndi styrene yogwira monoma mu utoto wa impregnation, kupangitsa pamwamba pa workpiece kukhala yomamatira.
● Nkhani zofananira. Mayeso ofananira amayenera kuchitidwa kuti penti yoyimbidwayo igwirizane kwathunthu ndi zinthu zina zomwe zili mu insulation system.
●Nkhani zokhudza kuphika. Ma vanishi osungunuka opangidwa ndi zosungunulira amakhala ndi zosungunulira zambiri. Nthawi zambiri, njira ziwiri kapena kuposerapo, kuphika komanso kutentha pang'onopang'ono kumawonjezera kutentha kumagwiritsidwa ntchito poletsa mikwingwirima kapena mipata mufilimu ya utoto ndikuwongolera magwiridwe antchito ndi moyo wakutchinjiriza koyilo. Njira yophika yopangira ma vanishi osasungunulira amayenera kusamala kuti musamayendetse guluu wambiri. Kuphika mozungulira kumatha kuchepetsa kuthamanga kwa guluu.
●Nkhani zakuwonongeka kwa chilengedwe. Njira zoyenerera ziyenera kuchitidwa pofuna kuwongolera mpweya wosungunulira ndi styrene zomwe zimatulutsidwa panthawi ya mimba ndi kuphika mkati mwazovomerezeka zovomerezeka.
