Sheath - yog dab tsi? Rau ib tus neeg zoo tib yam, lo lus no yuav ua rau muaj kev txaus siab. Nws tsis paub meej tias nws txhais li cas. Txawm li cas los xij, qhov no yog qhov tsim nyog heev hauv kev tsim khoom. Nws yog ib qho yooj yim los ua nws yog tias koj muaj cov txuj ci tsim nyog. Yog li, teb cov lus nug, lub plhaub - nws yog dab tsi, nws yuav tsum tau hais - yog ib qho dawb paug uas yog siv los tsim cylindrical thiab conical lug. Nws yog tsim los ntawm cov ntawv hlau los ntawm welding. Rov qab xaus koom ua ib lub raj, lub pas dej, lossis ntug.
pib qhov twg
Kev tsim cov plhaub pib nrog kev xaiv cov khoom tsim nyog. Ntau xyoo ntawm kev xyaum qhia tau hais tias qhov zoo tshaj plaws ntawm lawv yog steel 09X18H10T. Nws yog qhov zoo dua li lwm tus rau vuam. Tsis tas li ntawd, cov hlau no tso cai rau koj xaiv los ntawm ntau hom vuam. Qhov kawg yog qhov tseem ceeb heev. Xaiv txoj kev vuam zoo meej yog qhov nyuaj heev, tab sis tsim nyog. Qhov zoo tshaj plaws nyob rau hauv cov ntaub ntawv no yog electro-beammethod.
Qhov zoo ntawm ELM
Lub plhaub - yog dab tsi, peb twb pom lawm. Tam sim no cia saib yog vim li cas txoj kev vuam no siv hauv nws cov khoom siv. Ua ntej tshaj plaws, nws yog qhov zoo ntawm cov seam. Nws hloov tawm txhim khu kev qha, thiab qhov no yog qhov tseem ceeb tshaj plaws. Txhua yam tsis xws luag uas tshwm sim los ntawm vuam yog yooj yim tshem tawm. Cov txheej txheem tuaj yeem ua tshuab. Electron beam vuam muab cov khoom tsim tau siab. Yog tias peb muab piv nrog lwm txoj hauv kev, ces qhov ntsuas ntawm qhov kawg yuav qis dua 20 npaug. Hauv qhov no, ELM yog txoj hauv kev uas lub plhaub tau ua. Cov duab tuaj yeem pom - cov zis yog ib yam khoom zoo.
ELM zoo
Nws kuj tau sau tseg tias thaum lub sij hawm EL vuam, cua sov sai sai tawm ntawm qhov chaw ua haujlwm. Nrog rau ib qho me me ntawm cov cua sov, uas yog tsim nyog rau txoj kev vuam no, me ntsis deformation ntawm cov khoom tsim tau. Tau kawm cov lus teb rau lo lus nug, lub plhaub - nws yog dab tsi, tej zaum koj yuav nkag siab - qhov no yog ib yam khoom ntawm ntau qhov sib txawv, uas yog ib qho yooj yim los ua yog tias koj paub cov cuab yeej thiab muaj qee yam kev txawj ntse.

Kab lus no tshawb txog cov yam ntxwv ntawm kev sau se nrov tshaj plaws - yooj yim. Qhov zoo thiab qhov tsis zoo ntawm qhov system, cov xwm txheej ntawm daim ntawv thov, kev hloov pauv thiab kev tshem tawm tau nthuav tawm.

Hnub no, ntawm cov cuab yeej tshuaj ntsuam xyuas kev lag luam, kev sau zoo heev ntawm cov txheej txheem thiab cov txheej txheem ntawm kev txheeb xyuas nyiaj txiag tau sau tseg. Lawv txawv hauv cov hom phiaj, kev xaiv ua pab pawg, xwm txheej lej, sijhawm, thiab lwm yam. Xav txog cov txheej txheem ntawm kev txheeb xyuas nyiaj txiag hauv kab lus
Cov txheej txheem txheej txheem rau kev tsim cov khoom qab zib: cov ntsiab lus
Cov txheej txheem ntws los ntawm kev tsim cov khoom noj khoom haus muaj qee qhov zoo sib xws ntawm kev npaj cov khoom siv raw. Tab sis kev tsim khoom ntawm cov khoom tshwj xeeb yuav tsum tau ua raws li ntau yam kev ua haujlwm thev naus laus zis
Vuam hauv qhov chaw tiv thaiv roj: ua haujlwm thev naus laus zis, txheej txheem piav qhia, cov txheej txheem ua tiav, cov khoom tsim nyog thiab cov cuab yeej, cov lus qhia ua haujlwm ib ntus thiab cov lus qhia kws tshaj lij
Vuam thev naus laus zis yog siv hauv ntau ceg ntawm tib neeg kev ua haujlwm. Versatility tau ua vuam nyob rau hauv ib puag ncig tiv thaiv roj ib qho tseem ceeb ntawm kev tsim khoom. Qhov ntau yam no ua rau nws yooj yim los txuas cov hlau nrog lub thickness ntawm 1 hli mus rau ob peb centimeters nyob rau hauv txhua txoj hauj lwm nyob rau hauv qhov chaw. Vuam nyob rau hauv ib puag ncig tiv thaiv yog maj mam hloov cov tsoos electrode vuam
Kev kho dua tshiab ntawm qhov chaw los ntawm vuam thiab ntog: cov txheej txheem thiab cov txheej txheem ntawm kev kho dua tshiab, nta, txheej txheem thev naus laus zis
Vuam thiab surfacing thev naus laus zis ua rau nws ua tau zoo los kho cov hlau seem, muab cov qib siab ntawm kev ntseeg siab thiab ua haujlwm ntev ntawm cov khoom. Qhov no tau lees paub los ntawm kev xyaum siv cov txheej txheem no thaum ua haujlwm kho hauv ntau qhov chaw - los ntawm kev kho tsheb mus rau kev tsim cov hlau dov. Hauv tag nrho cov nyiaj ua haujlwm ntawm kev kho cov qauv hlau, kev kho dua tshiab ntawm qhov chaw los ntawm kev vuam thiab surfacing yuav siv li 60-70%
