Cov tshuaj pleev xim impregnation yog siv los pleev cov kauj hluav taws xob thiab cov xov hlau kom puv qhov sib txawv hauv, yog li cov xov hlau ntawm cov kauj thiab cov xov hlau thiab lwm yam khoom siv rwb thaiv tsev tau sib txuas ua ke los txhim kho lub zog hluav taws xob, cov khoom siv kho tshuab, kev ua kom sov thiab cov khoom tiv thaiv ntawm cov kauj hluav taws xob rwb thaiv tsev. Ms. Can yuav tham luv luv nrog koj txog cov tshuaj pleev xim impregnation hnub no, vam tias yuav pab nrog kev tswj xyuas zoo ntawm cov txheej txheem.
1 Cov kev cai yooj yim rau cov roj hmab impregnation hluav taws xob
● Cov viscosity tsawg thiab cov khoom khov siab kom ntseeg tau tias muaj permeability zoo thiab cov xim dai ntau npaum li cas;
● Kev ruaj khov zoo thaum lub sijhawm khaws cia thiab siv;
● Cov yam ntxwv zoo rau kev kho thiab ziab, kho sai, kub tsawg, ziab sab hauv zoo;
● Lub zog sib txuas siab, yog li cov khoom siv hluav taws xob tuaj yeem tiv taus qhov ceev ceev thiab lub zog cuam tshuam ntawm lub tshuab;
● Sib xws nrog lwm cov khoom siv sib xyaw;
● Kev ua tau zoo ntawm ib puag ncig.
2 Kev faib tawm thiab cov yam ntxwv ntawm cov kua roj impregnation
● Cov kua roj pleev rau cov kuab tshuaj. Cov kua roj pleev rau cov kuab tshuaj muaj cov kuab tshuaj, thiab nws cov khoom khov (feem ntau yog li ntawm 40% thiab 70%. Cov kua roj pleev rau cov kuab tshuaj uas muaj cov khoom khov ntau dua 70% hu ua cov kua roj pleev rau cov kuab tshuaj qis, tseem hu ua cov kua roj pleev rau cov kuab tshuaj siab.
Cov kua roj vanish impregnation muaj kev ruaj khov zoo, permeability zoo thiab cov khoom ua zaj duab xis, thiab pheej yig dua, tab sis lub sijhawm dipping thiab ci ntev, thiab cov kuab tshuaj seem yuav ua rau muaj qhov sib txawv ntawm cov khoom impregnated. Cov kuab tshuaj volatile kuj ua rau muaj kuab paug rau ib puag ncig thiab pov tseg, thiab nws siv tsawg. Nws feem ntau yog siv rau impregnation ntawmcov cav tsis tshua muaj zogthiab cov electrical windings.
Cov kua roj vanish impregnation uas tsis muaj kuab tshuaj feem ntau yog impregnated los ntawm kev immersion, thiab lub tshuab nqus tsev siab impregnation thiab dripping kuj tseem siv tau.
Cov kua roj pleev uas tsis muaj kuab tshuaj yuav kho tau sai, lub sijhawm luv luv rau kev tsau thiab ci, tsis muaj qhov sib txawv ntawm huab cua hauv cov rwb thaiv tsev uas tau muab tso rau, muaj kev ruaj khov zoo, thiab muaj cov khoom siv hluav taws xob thiab tshuab siab. Cov kua roj pleev uas tsis muaj kuab tshuaj tau raug txhawb nqa dav dav thiab siv los hloov cov kua roj pleev uas tsis muaj kuab tshuaj hauv cov tshuab hluav taws xob siab, cov cav, cov kab ntau lawm loj, cov kab ntau lawm ceev ceev, thiab qee lub cav tshwj xeeb thiab cov khoom siv hluav taws xob. Txawm li cas los xij, lub sijhawm khaws cia ntawm cov kua roj pleev uas tsis muaj kuab tshuaj yog luv luv. Cov kua roj pleev uas tsis muaj kuab tshuaj tuaj yeem raug muab tso rau los ntawm kev muab tso rau hauv dej, kev muab tso rau hauv dej tas mus li, kev muab tso rau hauv dej dov, kev muab tso rau hauv dej ntws thiab kev muab tso rau hauv dej siab.
3 Cov kev ceev faj rau kev siv cov roj pleev impregnation
●Kev tswj xyuas qhov zoo ntawm cov xim pleev thaum siv. Cov xim tsis muaj kuab tshuaj yog cov khoom sib xyaw ua ke uas tuaj yeem ua polymerizable. Ntau hom xim pleev uas tsis muaj kuab tshuaj yuav ua polymerize nws tus kheej rau ntau qib thaum khaws cia thiab siv. Kev tswj xyuas tsis zoo yuav ua rau qhov kev ua polymerization no sai dua. Thaum cov xim tsis muaj kuab tshuaj hauv cov khoom siv impregnation tsim cov gel, nws yuav khov sai thiab raug pov tseg hauv 1 txog 2 hnub, ua rau muaj xwm txheej loj thiab kev poob. Yog li ntawd, qhov zoo ntawm cov xim pleev uas tsis muaj kuab tshuaj uas siv yuav tsum tau tswj xyuas nruj me ntsis, thiab yuav tsum tau ua cov kev ntsuas kom ntseeg tau tias qhov zoo ntawm cov xim ruaj khov.
(1) Tsis tu ncua taug qab thiab saib xyuas qhov zoo ntawm cov xim pleev impregnating uas siv. Cov khoom tshuaj xyuas thiab cov voj voog tshuaj xyuas tuaj yeem tsim tau raws li cov xim pleev impregnating siv, cov khoom siv txheej txheem impregnation thiab cov haujlwm tsim khoom. Cov khoom tshuaj xyuas feem ntau suav nrog qhov ceev, qhov ceev, lub sijhawm gel, cov dej noo thiab cov ntsiab lus diluent nquag. Yog tias qhov ntsuas zoo ntawm cov xim pleev tshaj qhov txwv sab saud ntawm cov ntsuas kev tswj sab hauv, xim tshiab lossis lwm yam kev ntsuas yuav tsum tau ua tam sim ntawd los kho nws.
(2) Tiv thaiv kom cov dej noo thiab lwm yam tsis huv nkag mus rau hauv cov xim pleev xim. Txawm yog epoxy lossis polyester solvent-free impregnating paint yog rhiab heev rau cov dej noo. Me ntsis ntawm cov dej noo nkag mus rau hauv lub cev yuav ua rau cov xim viscosity nce sai. Cov dej noo thiab cov khoom tsis huv yuav tsum tau tiv thaiv kom tsis txhob nkag mus rau hauv cov xim thaum lub sijhawm thauj mus los, khaws cia thiab siv cov xim pleev xim. Cov dej, huab cua thiab cov khoom tsis muaj zog sib xyaw hauv cov xim tuaj yeem tshem tawm los ntawm kev siv lub tshuab nqus tsev thiab cov khoom siv degassing txheej xim, thiab cov kua xim tuaj yeem lim los ntawm cov khoom siv lim. Cov av noo hauv cov xim raug lim tawm tas li kom cov resin ntshiab.
(3) Xaiv qhov kub ntawm impregnation kom raug kom cov viscosity ntawm cov xim pleev kom txog qhov nqi teev tseg. Qhov no tuaj yeem xaiv raws li qhov nkhaus viscosity-kub ntawm cov xim pleev, thaum xav txog qhov sib txawv ntawm cov khoom siv txias-dip thiab cov khoom siv kub-dip. Yog tias qhov kub dipping siab dhau, nws yuav muaj qhov tsis zoo rau qhov ruaj khov viscosity ntawm cov xim pleev; yog tias qhov kub dipping qis dhau, qhov viscosity yuav siab thiab qhov cuam tshuam dipping yuav tsis zoo.
(4) Tsis tu ncua ncig thiab do cov kua xim kom tswj tau qhov kub ntawm cov kua xim hauv lub tank xim thiab cov kav dej kom qis li qis tau kom tiv thaiv cov kua xim hauv cov kav dej kom tsis txhob gelling thiab khov, uas yuav thaiv cov kav dej xim.
(5) Ntxiv cov xim tshiab tsis tu ncua. Lub voj voog ntxiv thiab qhov ntau npaum li cas nyob ntawm txoj haujlwm tsim khoom thiab qhov xwm txheej ntawm cov xim. Los ntawm kev ntxiv cov xim tshiab hauv cov haujlwm tsim khoom ib txwm muaj, cov xim impregnation hauv lub tank feem ntau tuaj yeem siv tau ruaj khov rau lub sijhawm ntev.
(6) Kev khaws cia kub qis ua rau cov xim tsis sib xyaw sai. Qhov kub khaws cia tuaj yeem tswj tau qis dua 10 ° C. Rau lub sijhawm ntev uas tsis siv lossis muaj xwm txheej, qhov kub khaws cia yuav tsum qis dua, xws li -5 ° C.
Rau cov xim pleev uas muaj cov kuab tshuaj, qhov tseem ceeb yog xyuas kom meej qhov ceev thiab viscosity ntawm cov xim kom nws nyob hauv qhov ntau thiab tsawg tswj tau.
● Cov teebmeem ntawm cov khoom tsis huv rau kev kho cov xim polyester impregnation uas tsis tau saturated. Kev xyaum tau qhia tias cov ntaub ntawv xws li tooj liab thiab phenols muaj qhov cuam tshuam qeeb rau kev kho cov xim polyester impregnation uas tsis tau saturated. Qee cov ntaub ntawv ntxiv, xws li roj hmab thiab cov hlau enameled oily, yuav yaj lossis o los ntawm styrene active monomer hauv cov xim impregnation, ua rau qhov chaw ntawm cov khoom ua haujlwm impregnated nplaum.
● Teeb meem sib xws. Yuav tsum tau ua qhov kev ntsuam xyuas sib xws kom paub tseeb tias cov xim pleev rau hauv lub tshuab rwb thaiv tsev sib xws nrog lwm cov khoom siv hauv lub tshuab rwb thaiv tsev.
●Teeb meem ntawm cov txheej txheem ci. Cov xim pleev uas muaj cov tshuaj yaj muaj ntau cov tshuaj yaj. Feem ntau, ob lossis ntau cov txheej txheem ci, ci thiab maj mam nce qhov kub yog siv los tiv thaiv cov qhov lossis qhov sib txawv hauv cov xim pleev thiab txhim kho kev ua haujlwm thiab lub neej ntawm cov khoom rwb thaiv tsev. Cov txheej txheem ci ntawm cov xim pleev uas tsis muaj tshuaj yaj yuav tsum ceev faj kom tiv thaiv cov kua nplaum ntws ntau dhau. Kev ci rotary tuaj yeem txo cov kua nplaum ntws.
●Teeb meem ua rau ib puag ncig muaj kuab paug. Yuav tsum muaj kev ntsuas kom zoo los tswj cov pa roj thiab cov styrene uas tawm thaum lub sijhawm ua kom cov tshuaj yaj thiab cov styrene yaj hauv cov txheej txheem ci kom tsis pub dhau qhov ntau thiab tsawg uas tau teev tseg.
