Peb lub tuam txhab 3 Qhov Ncauj Yoke Phaj yog lub hauv paus fais fab haum rau siab -voltage thiab ultra-siab-voltage kis kab thiab substations. Nws yog tsuas yog siv rau cov neeg kho tshuab kev sib txuas thiab thauj khoom faib ntawm ntauwd crossarms, insulator strings, thiab conductor clamps. Nws cov khoom zoo ncaj qha cuam tshuam rau kev ua haujlwm kev nyab xeeb, kev ruaj ntseg ntawm cov qauv, thiab kev pabcuam lub neej ntawm cov kab sib kis. Nyob rau hauv lub sij hawm ntev - siv nyob rau hauv complex ib puag ncig, lub yoke phaj yuav tsum tau tiv thaiv ntau yam kev ntxhov siab, xws li nro, dabtsi yog khoov, torsion, vibration, cua loads, icing loads, thiab kub hloov, thaum kuj tiv thaiv corrosion los ntawm acid los nag, ntsev tsuag, thiab muaj kuab paug. Yog li ntawd, cov qauv nruj yog siv rau kev ua haujlwm ntawm cov khoom siv raw, molding precision, txhua yam muaj zog, thiab qhov zoo ntawm cov tshuaj tiv thaiv -corrosion txheej. Txawm hais tias cov qauv no tau ua raws li muaj feem cuam tshuam nrog cov txheej txheem tsim khoom.
Cov ntaub ntawv nyoos yog lub hauv paus rau kev txiav txim siab qhov kawg ntawm cov khoom siv kho tshuab thiab kev pabcuam lub neej ntawm 3 Qhov Rooj Yoke Plate. Kev siv cov khoom siv rov ua dua tshiab thiab cov hlau tsis zoo yog txwv nruj rau cov khoom no. Cov qauv hlau uas ua tau raws li lub teb chaws thiab thoob ntiaj teb cov qauv yuav tsum raug xaiv, thiab yuav tsum tau ua cov txheej txheem tshuaj xyuas nruj heev. Cov xwm txheej tseem ceeb ntawm daim ntawv thov raug muab faib ua cov kab sib kis zoo tib yam, kab hauv cov cheeb tsam hnyav hnyav, thaj chaw ntsev ntsev ntawm ntug hiav txwv, thiab siab -load ultra- cov kab hluav taws xob siab, sib xws rau cov khoom sib txawv:
Cov kab kev thauj khoom txheem: Q235B carbon structural steel raug xaiv, muaj cov yas zoo, weldability, thiab kev ua haujlwm txias, nrog tus nqi qis, ua tau raws li kev xav tau ntawm engineering;
Nruab nrab- cov kab siab load: Q355B qis- alloy siab- lub zog ntawm cov qauv hlau raug xaiv, nrog lub zog muaj zog ntau dua, zoo heev tiv thaiv kev deformation thiab tawg, haum rau loj spans thiab hnyav load scenarios;
Tshwj xeeb corrosive ib puag ncig: Q355NH weathering steel lossis 304/316 stainless hlau tuaj yeem xaiv los txhim kho corrosion thiab txo cov nqi kho tom qab;
Phaj specifications mas yog kub- dov steel daim hlau, nrog ntau thicknesses ntawm 12mm, 14mm, 16mm, 18mm, 20mm, thiab 22mm. Dav thiab ntev yog kho raws li qhov ntev ntawm lub phaj txuas kom tsis muaj qhov tsis xws luag xws li delamination, tawg, lossis ntau dhau oxide nplai.
Tom qab cov khoom siv raw tuaj txog ntawm lub Hoobkas, lawv yuav tsum tau kuaj xyuas, uas yog thawj kauj ruam ntawm kev tsim cov 3 Qhov Rooj Yoke. Daim ntawv pov thawj zoo ntawm steel mills raug kuaj xyuas kom paub meej tias cov tshuaj muaj pes tsawg leeg thiab cov khoom siv tshuab ua tau raws li cov qauv. Cov hlau phaj saum npoo yog tiaj tus, tsis muaj kab nrib pleb, folds, nti, delamination, thiab npuas; oxide nplai yog ntom thiab tsis tev tawm. Thickness tolerances, ntev thiab dav tolerances raug soj ntsuam siv daim kab xev ntsuas, calipers, thiab micrometer los xyuas kom meej machining nyiaj txaus. Tom qab dhau kev soj ntsuam, ya raws - pov thawj, xeb- pov thawj, thiab kev tswj daim ntawv lo yog siv los tiv thaiv kev sib xyaw thiab xeb.
Blanking yog thawj txheej txheem rau 3 qhov Yoke Phaj. Lub hom phiaj yog los txiav cov kub- dov steel phaj rau hauv cov duab dawb paug, kom ntseeg tau qhov tseeb qhov tseeb, txiav zoo, thiab siv cov khoom siv. Cov txheej txheem tseem ceeb yog CNC txiav thiab tuag stamping, nrog CNC txiav yog thawj txoj hauv kev rau ntau lawm. Rau me me -batch, ntau- specification customization, CNC plasma / nplaim taws txiav tshuab yog siv, muab siab yooj, tshem tawm qhov xav tau pwm, thiab hloov mus rau peb - qhov Yoke Phaj nrog qhov sib txawv qhov sib txawv thiab qhov ntev. Rau loj- teev cov txheej txheem tsim khoom, kaw- lub voj voog xovxwm nrog cov khoom siv stamping tuag yog siv, muab kev ua haujlwm siab thiab sib xws, haum rau loj- nplai tsim cov qauv ruaj khov.
Lub luag haujlwm tseem ceeb ntawm 3 qhov Yoke Phaj tso siab rau peb lub qhov txuas rau kev sib txuas. Qhov tseeb ntawm cov haujlwm ntawm lub qhov, qhov kam rau ntawm lub qhov taub, thiab qhov roughness ntawm lub qhov phab ntsa ncaj qha cuam tshuam rau kev sib dhos ua haujlwm thiab kev sib koom ua ke ntawm lub zog faib, ua rau lawv lub hom phiaj tseem ceeb ntawm cov txheej txheem machining. Siv lub tiaj tiaj thiab kawg lub ntsej muag ntawm lub phaj sib txuas raws li cov ntaub ntawv qhia, vises lossis cov cuab yeej tshwj xeeb yog siv rau kev kho kom ruaj ntseg clamping thiab tiv thaiv kev txav los yog xoob thaum lub sijhawm ua haujlwm. Txhua lub qhov qhib thiab phaj npoo yuav tsum tau chamfered rau C1-C2, tshem tawm cov burrs ntse. Tom qab tag nrho cov saum npoo yog hauv av siv lub log sib tsoo thiab lub log nrov plig plawg, ua rau lub ntsej muag du tsis muaj cov cuab yeej, burrs, thiab oxide nplai, muab lub hauv paus zoo rau tom qab kub -dip galvanizing.
Xav txog qhov ntev -ntev kev pabcuam sab nraum zoov ntawm 3 qhov yoke daim hlau, kub-dip galvanizing yog tib txoj kev los tiv thaiv- cov txheej txheem corrosion. Its core function is to form a dense zinc layer, achieving a dual anti-corrosion effect of physical shielding and cathodic protection. Qhov zoo ntawm zinc txheej ncaj qha txiav txim siab cov khoom siv lub neej. Cov txheej txheem kub - dip galvanizing yog raws li nram no: degreasing → dej ntxuav → pickling thiab xeb tshem tawm → dej ntxuav → flux kho → ziab → kub -dip galvanizing → txias → passivation → tiav → tshuaj xyuas. Cov txheej txheem no tshem tawm cov roj, txiav cov kua dej, thiab xeb- tiv thaiv cov roj los ntawm qhov chaw ua haujlwm kom tsis txhob cuam tshuam cov adhesion ntawm zinc txheej. Alkaline tshuaj degreasing yog siv, nrog ib tug degreasing tus neeg sawv cev kub ntawm 50-70℃thiab immersion lub sij hawm ntawm 10-15 feeb, ntxiv los ntawm txhua yam nplawm kom ua tiav ntub dej ntawm lub workpiece nto. Kev ntxuav dej huv kom ntseeg tau tias tsis muaj tus neeg sawv cev degreasing seem ua ntej galvanizing.
Tom qab galvanizing, lub workpiece yog finely tiav los xyuas kom meej tias nws ua tau raws li lub installation thiab zoo li yuav tsum tau. Cov seem zinc me ntsis thiab cov zinc nodules hauv zos ntawm cov hangers raug tshem tawm, thiab cov khoom ua haujlwm yog polished nrog cov cuab yeej tshwj xeeb yam tsis muaj kev puas tsuaj rau zinc txheej. Cov mounting qhov yog ces refinished los xyuas kom meej tias lub qhov yog unobstructed thiab dawb los ntawm zinc txheej thaiv. Cov dav hlau raug kho kom raug thiab kho kom tshem tawm galvanizing kub deformation. Qhov sib txuam bolts, txiv ntseej, lub tshuab ntxhua khaub ncaws, thiab lub caij nplooj ntoos hlav ntxhua khaub ncaws tau sib sau ua ke thiab tshuaj xyuas kom ntseeg tau tias cov khoom sib dhos yog hloov tau thiab siv tau.
