Sidee loo rakibaa tuubooyinka derbiga ee loo yaqaan 'Epoxy Resin'?

Rakibaaddabushqadaha derbiga dhex mara ee resin epoxywaa hawlgal koronto oo sax ah oo si adag loo nidaamiyay, oo inta badan loo qaybiyay laba xaaladood: horay loo sii rakibay (lagu rakibay isku mar inta lagu jiro dhismaha derbiga) iyo ka dib la geliyay (la rakibay ka dib marka derbiga la sameeyo). Kuwa soo socda waa tallaabooyinka guud ee rakibidda iyo qodobbada muhiimka ah ee ku salaysan heerarka warshadaha (sida GB 50149-2010, DL/T 5221-2016).

I. Tallaabooyinka Guud ee Rakibaadda
1. Diyaarinta kahor rakibidda
Xaqiijinta cabbiraadda: Xaqiiji in danabka la qiimeeyay, hadda, iyo masaafada gurguurta ee bushing-ku ay la jaan qaadayaan sawirrada naqshadeynta, oo hubi haddii ay jiraan dildilaacyo ama waxyeellooyin ku yimaada muuqaalka.
Cabbiraadda iyo booska: Isticmaal heer laysar ah ama xariiq nuurad ah si aad u calaamadiso xariiqda dhexe ee derbiga si aad u hubiso saxnaanta booska godka oo aad uga fogaato cadaadiska saaran baska ama fiilada marka la qasbo hadhow.
Habaynta godka: Dhexroorka godka badanaa waa 5-10mm ka weyn dhexroorka dibadda ee godka si loo oggolaado hagaajinta iyo buuxinta agabka shaabadaysan. Cidhifka godka waa in la simiyaa oo laga saaraa burrs-ka si looga hortago waxyeelada soo gaarta fiilada ama dusha sare ee godka.
2. BushingKu rakibidda iyo xidhitaanka
Habka Hagaajinta: Wixii loogu talagalay bushing epoxy resin oo leh flanges bir ah (sida flanges aluminium ah), boolal ballaarin ah ama barroosin kiimiko ah ayaa badanaa loo isticmaalaa in lagu hagaajiyo flanges-ka labada dhinac ee derbiga. Muddada lagu taliyay ee hagaajinta waa ≤ 300mm si loo hubiyo in bushing-ku uusan dabacsanayn inta lagu jiro gariirka hawlgalka.
Buuxinta Shaabadeynta: Tani waa tallaabo muhiim u ah ka hortagga biyaha, ka hortagga dabka, iyo ka hortagga jiirka.
Buuxinta Boosaska: Farqiga wareegsan ee u dhexeeya bushing-ka iyo derbiga waa in lagu buuxiyaa butty aan dab-damin ama shaabad aan dab-damin, iyadoo lagu taliyay dhumucdiisuna tahay ≥ 20mm si loo hubiyo shaabad cufan oo aan lahayn meel bannaan.
Daawaynta Biyo-mareenka: Si loogu isticmaalo gudaha derbiga dibadda ama meelaha qoyan, dhammaadka dibadda eebuufinwaa in hoos loogu fooraraa 15° - 30°, waana in la rakibaa dabool biyuhu aanay dib ugu soo noqon.
3. Gelinta iyo Isku xirka Kondurator-ka
Ilaalinta Gelinta: Kahor intaadan gelin basaska ama fiilooyinka, hubi in derbiga gudaha ee bushing-ku uu siman yahay. Fiilooyinka, waxaa lagu talinayaa in lagu xidho tuubo ilaalin ah (sida tuubo jiingad ah) qaybta gelinta si looga hortago in geesaha fiiqan ay xoqaan lakabka dahaarka.
Adkeynta Xidhiidhka: Marka la xirayo terminal-ka, boolalku waa in lagu adkeeyaa wareegga caadiga ah si looga fogaado kuleylinta maxalliga ah sababtoo ah xiriir xumo. Kadib isku xirka, hubi in giraanta shaabadu ay nadiif tahay si looga hortago qoyaanka inuu soo galo.
4. Tijaabinta Rakibaadda Kadib
Tijaabada Dahaarka: Ka dib rakibidda, iska caabbinta dahaarka waa in lagu tijaabiyaa mitir 2500V ah. Qiimaha u-qalmitaanka badanaa waa ≥1000MΩ (ama iyadoo la raacayo heerarka gaarka ah).
Tijaabada Danabka ee u Adkeysiga: Wixii danab sare leh (sida 10kV iyo wixii ka sareeya), waa in la sameeyaa tijaabo danab u Adkeysiga Soo noqnoqoshada Korontada (tusaale ahaan, 10kV bushing oo lagu sameeyo 42kV/5 daqiiqo iyada oo aan la jabin).
II. Taxaddarrada Aasaasiga ah
Ma jiro garaac adag: Inkasta oo resin epoxy uu leeyahay xoog sare, iska caabbinta saameyntiisu ma fiicna sida tan birta. Inta lagu jiro rakibidda, si adag ayaa loo mamnuucay in si toos ah loogu dhufto jirka bushing dubbe ama walxo kale oo adag si looga hortago dildilaacyo yaryar oo ku dhaca lakabka dahaarka gudaha, taasoo keeni karta dheecaan qayb ah.
Ka Hortagga Qoyaanka iyo Nadiifinta: Kahor rakibidda, ku masax dusha sare ee gudaha iyo dibadda ee bushkulka alkohol aan biyo lahayn si aad u hubiso inaysan jirin boodh ama saliid. Markaad ka shaqeyneyso cimilada qoyan, qaado tallaabooyin aan qoyaan lahayn si aad uga hortagto in uumiga uu saameyn ku yeesho waxqabadka dahaarka.
Lacagta Ballaarinta iyo Qaloocinta: Deegaannada leh kala-goysyada ballaarinta ama kala duwanaanshaha heerkulka oo weyn, waa in loo qoondeeyaa 10-15mm oo loogu talagalay ballaarinta iyo isku-soo-ururinta inta u dhaxaysa bushing-ka iyo gudbiyaha, ama waa in la rakibaa magdhaw caag ah si looga hortago isbeddelka bushing-ka sababtoo ah ballaarinta kulaylka iyo isku-soo-ururinta.
Shuruudaha Dhulka: Haddii buushku leeyahay gaashaan bir ah ama flange bir ah, waa in si kalsooni leh loo dejiyaa, iska caabbinta dhulkana waa inay noqotaa ≤4Ω si looga takhaluso danab la kiciyey.
III. Maareynta Muuqaalka Gaarka ah
Rakibaadda Ku-meel-gaarka ah: Kahor inta aan la shubin derbiga shubka ah, bushku wuxuu u baahan yahay in lagu dhejiyo meesha uu ku yaal. Waqtigan xaadirka ah, fiiro gaar ah ayaa loo leeyahay saxnaanta booska si looga hortago in bushku dhaqaaqo inta lagu jiro habka shubista. Labada daraf ee bushku waa inay ka soo baxaan derbiga in ka badan 50mm si loo fududeeyo daawaynta shaabadda marxaladda dambe.
Rakibaadda Dibadda: Bush-ka nooca dibadda ah badanaa waxay leeyihiin goonno ka hortagta wasakhowga. Inta lagu jiro rakibidda, fiiro gaar ah u yeelo jihada goonnada (badanaa hoos), oo si joogto ah u nadiifi wasakhda goonnada si looga hortago in boodhku ku ururo.
Talooyinka Badbaadada: Shaqada rakibidda waa in lagu qabtaa xaalad aan firfircoonayn, calaamadda digniinta "Ha Xidhin" waa in la sudhaa. Rakibaadda bushings-ka danab-sare leh waxaa lagula talinayaa inay ka shaqeeyaan xirfadlayaal koronto yaqaanno ah oo aqoon u leh.
