Cov txheej txheem tseem ceeb ntawm kub-dip galvanized yoke daim hlau revolves nyob ib ncig ntawm "substrate processing → nto pretreatment → kub-dip galvanizing → post- kho → tshuaj xyuas thiab xa khoom". Txhua kauj ruam yuav tsum muaj kev tswj xyuas nruj tshaj qhov tseeb, huv si, thiab txheej txheej zoo kom ntseeg tau tias cov khoom siv kho tshuab, kev tiv thaiv corrosion, thiab kev sib raug zoo ntawm cov hlau txuas. Cov kauj ruam tshwj xeeb yog raws li nram no:
Kev xaiv substrate: Raws li qib voltage (110kV / 220kV / 500kV / UHV) thiab rated load ntawm cov phaj txuas, xaiv qis alloy siab zog steel daim hlau lossis forgings uas ua tau raws li cov qauv xws li GB / T 700 (Q235) thiab GB / T 1591 (Q345) kom ntseeg tau tias lub zog tensile ntawm nws tus kheej. tawg vim defects nyob rau hauv lub substrate).
Cov ntaub ntawv txiav: Siv CNC nplaim taws txiav, plasma txiav, lossis laser txiav, cov phaj hlau raug txiav rau hauv qhov tsis muaj raws li cov duab (lub kaum sab xis, daim duab peb sab, Y- zoo li, thiab lwm yam) ntawm cov ntawv sib txuas ntawm daim duab kos duab. Cov ntsiab lus tseem ceeb: Cov npoo txiav yuav tsum tiaj tus, tsis muaj burrs, tawg, lossis oxide residue, thiab qhov kev ua yuam kev loj yuav tsum raug tswj tsis pub dhau ± 1 hli (kom paub meej qhov tseeb ntawm kev ua haujlwm tom ntej).
Stamping: Rau cov phaj tuab lossis hom uas yuav tsum muaj kev ntxhov siab, qhov khoob tom qab txiav yuav tsum tau muab tso rau hauv lub forging xovxwm lossis stamping xovxwm thiab tsim los ntawm kev tuag forging los ua kom cov nplej sab hauv ntawm cov hlau thiab txhim kho tag nrho lub zog.
Machining Qhov: Siv CNC drilling tshuab los yog machining chaw, ntsia liaj qhov rooj qhov, dai qhov, thiab lwm yam kev sib txuas interfaces ntawm kub -dip galvanized yoke phaj yog precision machined raws li cov kos duab. Lub qhov taub txoj kab uas hla yog tswj nyob rau hauv H12 qib (± 0.15mm), thiab qhov sib txawv qhov yuam kev yog tsawg dua los yog sib npaug rau ± 0.5mm kom ntseeg tau meej txuam nrog bolts ntawm insulators, clamps, thiab lwm yam khoom siv. Lub qhov npoo yog sib npaug (R Ntau dua lossis sib npaug li 2 hli) kom tsis txhob muaj kev ntxhov siab los ntawm cov npoo ntse thiab tiv thaiv txheej txheej thaum lub sij hawm galvanizing.
Ntug sib tsoo: Sib tsoo cov npoo txiav, qhov qhib, thiab qhov chaw ntawm cov phaj sib txuas siv lub tshuab sib tsoo los yog polishing tshuab kom tshem tawm burrs, flash, thiab machining marks; reshape thiab kho qhov chaw deformed kom paub meej tias qhov kev ua yuam kev flatness ntawm cov phaj txuas yog tsawg dua lossis sib npaug li 2 hli / m.
Alkaline degreasing: Muab cov phaj txuas rau hauv lub tank alkaline degreasing ntawm 60-80℃rau 10-20 feeb kom tshem tawm cov roj saum npoo, txiav cov kua dej, thiab hmoov av; yaug kom huv si nrog dej huv kom paub meej tias tsis muaj roj seem. Pickling rau xeb tshem tawm: Raus lub degreased txuas phaj nyob rau hauv ib tug 15-20% hydrochloric acid pickling tank rau 15-30 feeb kom tshem tawm cov nto oxide nplai, xeb, thiab dov oxide zaj duab xis; do tsis tu ncua thaum lub sij hawm pickling kom tsis txhob muaj xeb tshem tawm hauv qee qhov chaw.
Fluxing kev kho mob: Muab lub phaj rinsed rau hauv ib da dej ntawm 70-80℃thiab raus rau 3-5 feeb los tsim ib tug uniform flux zaj duab xis rau saum npoo. Cov yeeb yaj kiab no tuaj yeem cais cov huab cua thiab tiv thaiv oxidation theem nrab ntawm cov substrate; nws kuj txo qhov nro ntawm cov kua zinc, tso cai rau cov kua zinc kom sib npaug ntawm qhov chaw ntawm lub substrate.
Zinc immersion kev kho mob: Siv ib tug tshwj xeeb hanger rau vertically tso lub qhuav txuas phaj rau hauv cov zinc kua thiab raus rau 3-5 feeb kom ntseeg tau tias cov zinc kua tag nrho ntub dej ntawm lub substrate thiab tsim ib metallurgically bonded zinc- hlau alloy txheej + ntshiab zinc txheej composite qauv. Qhov no kuj yog cov txheej txheem tseem ceeb tshaj plaws nyob rau hauv kub-dip galvanized yoke daim hlau.
Kev tswj cov zinc txias: Cov zinc- cov phaj immersed tau maj mam tshem tawm ntawm cov kua zinc, thiab cov kua zinc ntau dhau ntawm qhov chaw yog tshuab los ntawm lub vibrating hanger lossis cua riam los tswj cov txheej tuab; tom qab ntawd lawv tau muab tso rau hauv lub tank dej txias kom txias sai, uas ua kom cov txheej txheem ua kom zoo dua qub thiab txhim kho hardness thiab hnav tsis kam;
Kev tu thiab polishing: Tom qab txias, siv cov hlau txhuam los yog lub log sib tsoo los ntxuav cov zinc nodules, zinc caws pliav, thiab cov cim fixture ntawm qhov kub ntawm qhov kub -dip galvanized yoke daim hlau kom zoo; ua qhov kev tu ncua ntawm qhov qhib kom tsis txhob muaj txheej txheej cuam tshuam rau kev nkag ntawm lub bolt.
