Qhov cuam tshuam rau cov nyhuv ntawm impregnating xim
(1) Qhov yuav tsum tau ntom ntub ntawm cov khoom uas tsis tuaj yeem. Qhov nplaim ntawm qhov huv si thiab qhuav yog qhov zoo rau lub infiltration ntawm cov xim. Yog hais tias cov khoom uas tsis tuaj yeem yog greased thiab lo av, qhov saum npoo tsis zoo rau lub infiltration ntawm cov xim, thiab nws kuj ua rau ntau degrees ntawm cov kab mob ntawm impregnated xim. Hauv particular, powdery debris hauv cov tub ntxhais yuav ua rau hluav taws xob tsis ua hauj lwm ntawm kev ntses.
(2) Cov cwj pwm txawv ntawm cov kua roj vanish kheej. Lub wettability ntawm impregnating varnish yog zoo txog kev zoo tom qab lub tivthaiv yog immersed. Yog hais tias cov cuab yeej ntawm cov kua roj voos yog zoo heev, nws yuav ua kom paub tseeb tias qhov kev nplua yog kom tiav, txwv tsis pub nws yog qhov yuav tsum tau kov lub hav zoov ntawm cov kua thiab cov insulating nplaim siab. Ua rau lub zog qis qis qis, uas cuam tshuam rau cov khoom siv hluav taws xob. VPI cov cuab yeej muaj peev xwm ua kom tau zoo tshaj qhov txaus siab ntawm txoj kev siv xim tshuab ua kom tiav.
Kev ntxhib yog qhov ntau ntawm cov nplaim ntawm ib cov kua nplaum los ntawm cov kua, uas yog muab lub kaum ntse ntse. Lub kaum ntse ntse yog lub kaum sab xis ntawm lub tangent mus rau theem ua kua ntawm qhov chaw uas muaj cov kua tau ob theem nyob rau hauv kev sib cuag, thiab lub tangent rau ntawm phab ntsa khoom. Tus me lub pob ntseg qis, qhov zoo dua qhov ntxiab; qhov ntau dua lub pob ntseg qe, qhov zuj zus qhov txhaws. Cov kua hluav taws xob ua kua yog ib qho kua deg hauv qhov capillary, thiab cov kua dej uas tsis yog vitream yog cov kua qaub nyob hauv lub hau. Ntawm no, nws yog qhov zoo tshaj plaws cov nyhuv ntawm kev sib cuag zoo ntawm tsev cog khoom ntawm cov roj ntsha thiab impregnated tsab xov xwm.
(3) Cov khoom siv rau cov khoom siv hluav taws tso pov tawm. Lub compatibility ntawm lub nplaum nyob rau hauv lub composite cov ntaub ntawv uas siv nyob rau hauv lub machining ntawm lub cev muaj zog windings nrog sib xws impregnating varnish yog tshwj xeeb yog ib qho tseem ceeb. Yog tias ob leeg tsis sib haum xeeb, nws yuav cuam tshuam txog kev muaj peev xwm thiab kev txuam ntawm qhov lacquer rau ntawm cov khoom uas muaj qhov sib txawv.
(4) Viscosity ntawm impregnating vanish. Thaum cov xim ntawm qhov xim muaj zog ntxiv, raws li qhov muaj zog nruj nce, cov ntaub ntawm cov xim muaj zog, uas cuam tshuam lub peev xwm ntawm qhov xim.
Ntxim rau kub ntawm dipping xim thiab kev luj xyuas ntawm cov nyhuv
● Kub cev thiab qhwv cov kab xev thawm rau lub cev thiab ntub dej
Nyob rau hauv tib lub impregnation mob, lub viscosity me me yooj yim permeates thiab ntub dej ntawm impregnated insulating khoom, thiab cov viscosity loj thiab nws yog yooj yim txeem thiab infiltrate. Raws li qhov kub nce, qhov viscosity ntawm impregnating varnish decreases, ces nyob rau hauv qhov kev tiv thaiv cov khoom tiv thaiv, xaiv qhov kub ntawm cov kua txiv hmab txiv ntoo impregnating yog qhov tseem ceeb rau kev ua tau zoo txaus siab rwb thaiv kev kho mob.
● Kub thiab txav ua kom muaj kua roj voos
Lub peev xwm ntawm kev ua kom tiav cov kua roj voos kheej kheej yog nyob ntawm cov ntsiab lus ntawm lacquer. Yog li ntawd, nws yog feem ntau yuav tsum tau hais tias cov kua roj vanish uas muaj impregnating muaj ib cov txheej txheem khoom siab, yog li ntawd cov xim muaj ib qho kev txhim kho zoo. Txij li cov ntsiab lus ntawm tib lub pob ntawm cov kua roj voos kheej kheej yog tib yam, thaum muaj qee cov ntsiab lus ntawm cov kua roj voos, kev siab dua, qhov siab dua, thiab qhov qis dua cov txheej txheem ntawm cov kua roj vanishing ntim; Qhov qis dua qhov cov ntsiab lus ntawm cov kua roj vanishing rau ib lub tsev ntim.
● Yam teeb meem uas cuam tshuam txog kev ntim ntawm cov xim muaj hlau
1) Qhov mob ntawm qhov chaw yog huv thiab qhuav, uas zoo rau infiltration, roj thiab cov av tsis zoo rau infiltration; 2) cov yam ntxwv ntawm cov xim xim ntoo nws tus kheej; 3) qhov sib thooj ntawm cov nplaum ntawm cov khoom siv insulating ntawm hnav ris tsho thiab cov xim pleev xim; 4) impregnating xim Viscosity; 5) qhov kub thiab txias.
● Kev ntsuam xyuas ntawm kev siv tshuaj tua kab thiab ziab tawm
Muaj ntau lub tshuab fais fab siv cov xim pleev xim rau kev ntsuam xyuas cov xim ntawm dipping, tab sis Ms. ntseeg hais tias yog tias cov xim muaj xim zoo nkauj, nws qhov peev xwm nkag mus yuav pluag. Qhov kawg nyhuv yog tsim ib lub plhaub khauj ntawm cov nplaim paj. Qhov tseeb tiag, qhov kev siv curing yog qhov ua tiav; ntawm qhov tsis sib thooj, yog tias cov xim muaj xim heev, qhov permeability yuav zoo, tab sis nws tsis yooj yim rau dai ntawm lub winding, thiab cov nyhuv nyhuv tseem tsis tau tiav.
Vim li no, cov neeg tsav tsheb sib txawv txawv tshwj xeeb rau cov txheej txheem no, tiam sis cov neeg tsav tsheb sib txawv yuav ua kom zoo dua qub thiab kuaj xyuas cov txheej txheem tsis xws li ua ntej ci, ntses thiab ziab raws li lawv cov khoom muaj xws li cov khoom, cov khoom siv thiab cov khoom siv. Coj raws li qhov tseeb tsis tas ua kom tau raws li qhov yuav tsum tau muaj ntawm nws cov khoom.
Yog tias koj xav yuav ib lub cav ua khoom siv hauv tsev, thov koj faj seeb rau lub tshuab fais fab.
