1. Txheej txheem cej luam
Roll welding yog ib hom kev tiv thaiv vuam. Nws yog ib txoj kev vuam nyob rau hauv uas cov workpieces tau sib sau ua ib lub puab tsaig lossis pob tw, thiab tom qab ntawd muab tso rau ntawm ob lub tshuab electrodes. Cov menyuam electrodes nias lub vuam thiab tig, thiab lub zog txuas ntxiv los yog cuam tshuam los ntawm kev siv los ua ib qho txuas txuas ntxiv. Yob vuam siv dav hauv kev tsim cov pob qij txha uas xav tau kev sib khi, thiab qee zaum siv los txuas cov hlau tsis sib txuas. Qhov tuab ntawm cov khoom siv hlau welded feem ntau yog 0.1-2.5 hli.
Bellows yog siv rau hauv li qub, feem ntau yog rau kev sib khi thiab kev sib cais. Nyob rau hauv ntau yam bellows li qub, txawm hais tias nws yog lub nres valve, lub throttle valve, lub regulating valve los yog lub siab txo valve, lub twj tso kua mis yog siv raws li ib tug packing-free sealing cais ntawm lub valve qia. Thaum lub sijhawm ua haujlwm ntawm lub valve, lub hauv siab thiab lub valve qia yog axially hloov thiab rov pib ua ke. Nyob rau tib lub sijhawm, nws kuj tiv taus lub siab ntawm cov kua thiab ua kom muaj kev sib khi. Piv nrog rau cov ntim ntim ntim, lub tshuab nqus tsev valve muaj kev ntseeg siab dua thiab kev pabcuam lub neej. Yog li ntawd, bellows li qub tau dav siv nyob rau hauv kev lag luam nuclear, roj av, tshuaj lom neeg kev lag luam, tshuaj, aerospace, thiab lwm yam. Nyob rau hauv cov ntaub ntawv siv, bellows feem ntau welded ua ke nrog rau lwm yam xws li flanges, kav thiab valve stems. Lub hauv paus yog welded los ntawm yob vuam, uas yog heev npaum thiab dav siv.
Lub tshuab nqus tsev nqus tsev vacuum uas tsim los ntawm peb lub tuam txhab yog siv nyob rau hauv uranium fluoride ib puag ncig qhov nruab nrab yog flammable, explosive thiab radioactive. Lub hauv paus yog ua los ntawm 1Cr18Ni9Ti nrog lub thickness ntawm 0.12 hli. Lawv txuas nrog lub valve disc thiab lub caj pas los ntawm yob vuam. Lub vuam yuav tsum muaj kev ruaj ntseg sealing kev ua tau zoo nyob rau hauv ib qho kev siab. Txhawm rau kom debug thiab hloov pauv cov khoom siv yob vuam uas twb muaj lawm kom ua tau raws li qhov yuav tsum tau ua, cov cuab yeej tsim thiab cov txheej txheem kuaj tau ua tiav, thiab ua tiav cov txiaj ntsig zoo.
2. Roll vuam khoom
FR-170 capacitor lub zog cia yob vuam tshuab yog siv, nrog lub zog cia capacitor muaj peev xwm ntawm 340μF, kev them nyiaj hloov pauv hloov pauv ntawm 600 ~ 1 000V, electrode hloov siab ntau ntawm 200 ~ 800N, thiab qhov nominal siab tshaj cia ntawm 170J . Lub tshuab siv lub zero-enclosed shaping circuit nyob rau hauv lub Circuit Court, uas tshem tawm qhov tsis zoo ntawm network voltage fluctuations thiab xyuas kom meej tias cov mem tes zaus thiab them voltage nyob ruaj khov.
3. Teeb meem nrog cov txheej txheem qub
1. Cov txheej txheem vuam tsis ruaj khov. Thaum lub sij hawm dov txheej txheem, nto splashes ntau, thiab vuam slag yooj yim adheres rau cov menyuam electrode, uas ua rau nws nyuaj heev rau siv cov menyuam tsis tu ncua.
2. Kev ua haujlwm tsis zoo. Vim hais tias lub hauv paus yog elastic, lub weld yog ib qho yooj yim mus deviate yam tsis muaj qhov zoo vuam tooling positioning, thiab cov electrode yog ib qho yooj yim mus kov lwm qhov chaw ntawm lub hauv siab, ua rau sparks thiab splashes. Tom qab ib lub lim tiam ntawm vuam, cov vuam xaus tsis zoo ib yam, thiab cov vuam sealing tsis ua raws li qhov yuav tsum tau ua.
3. Weld tsis zoo. Lub weld point indentation yog qhov sib sib zog nqus heev, qhov saum npoo yog overheated, thiab txawm tias ib nrab hlawv-los ntawm qhov tshwm sim. Lub vuam zoo tsim tsis zoo thiab tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm kev ntsuas roj.
4. Kev txwv ntawm cov nqi khoom. Lub foob pob hluav taws xob yog kim. Yog tias kub hnyiab tau tshwm sim, lub hauv caug yuav raug muab pov tseg, nce nqi khoom.
Xinfa vuam cov cuab yeej muaj cov yam ntxwv zoo thiab tus nqi qis. Yog xav paub ntxiv, thov mus saib:Vuam & txiav Manufacturers - Tuam Tshoj Vuam & Txiav Hoobkas & lwm tus neeg (xinfatools.com)
4. Kev tshuaj xyuas cov txheej txheem tseem ceeb
1. Electrode siab. Rau dov welding, lub siab thov los ntawm electrode ntawm lub workpiece yog ib qho tseem ceeb parameter cuam tshuam qhov zoo ntawm cov welding. Yog hais tias lub electrode siab tsawg dhau lawm, nws yuav ua rau lub cheeb tsam kub hnyiab-dhau, overflow, nto spatter thiab dhau heev lawm; Yog hais tias lub electrode siab dhau lawm, lub indentation yuav sib sib zog nqus heev, thiab lub deformation thiab poob ntawm electrode roller yuav tsum ceev.
2. Vuam ceev thiab mem tes zaus. Rau qhov sib khi yob weld, qhov denser cov ntsiab lus weld, qhov zoo dua. Qhov sib tshooj coefficient ntawm cov ntsiab lus weld yog qhov zoo dua 30%. Qhov kev hloov ntawm vuam ceev thiab mem tes zaus ncaj qha cuam tshuam qhov kev hloov ntawm qhov sib tshooj.
3. Kev them nyiaj yug capacitor thiab voltage. Hloov lub charging capacitor los yog them voltage hloov lub zog xa mus rau lub workpiece thaum vuam. Txoj kev sib txuam ntawm qhov sib txawv ntawm qhov sib txawv ntawm ob muaj qhov sib txawv ntawm qhov muaj zog thiab tsis muaj zog specifications, thiab txawv zog specifications yuav tsum tau rau cov khoom sib txawv.
4. Cov menyuam electrode kawg lub ntsej muag daim ntawv thiab loj. Feem ntau siv rau cov menyuam electrode cov ntaub ntawv yog F hom, SB hom, PB hom thiab R hom. Thaum kawg ntawm lub ntsej muag loj ntawm cov menyuam electrode tsis tsim nyog, nws yuav cuam tshuam qhov loj ntawm cov tub ntxhais weld thiab qhov nkag mus, thiab tseem yuav muaj qee yam cuam tshuam rau cov txheej txheem vuam.
Txij li cov kev xav tau zoo ntawm cov yob vuam cov pob qij txha yog feem ntau pom nyob rau hauv qhov zoo sealing thiab corrosion kuj ntawm cov pob qij txha, cov kev cuam tshuam ntawm kev nkag mus thiab sib tshooj yuav tsum tau txiav txim siab thaum txiav txim siab cov saum toj no tsis. Nyob rau hauv cov txheej txheem vuam tiag tiag, ntau yam tsis cuam tshuam rau ib leeg thiab yuav tsum tau ua tib zoo sib koom tes thiab hloov kho kom tau txais cov pob qij txha zoo.
