Hauv kev lag luam hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob, cov nqi siab tsis zoo yog "tsis pom kev tua" uas ua rau cov tuam txhab tau txais txiaj ntsig. Tsis ntev los no, ib qho ntawm peb cov neeg siv khoom hauv Bangladesh tau ntsib cov teeb meem thaum ua haujlwm a6-chaw nres tsheb cua sov phaj brazing tshuabrau kettles, uas ua rau lub brazing defect tus nqi siab li 10%. Qhov no tsis yog tsuas yog ua rau cov khoom pov tseg tab sis kuj cuam tshuam loj heev rau tag nrho cov kev tsim khoom.
Thaum tau txais kev tawm tswv yim, peb pab pawg engineering tsis yog muab kev qhia hauv online xwb; lawv tuaj txog ntawm cov neeg siv khoom lub Hoobkas hauv Bangladesh hauv 48 teev los ua haujlwm ntawm -qhov chaw kuaj mob. Qhov teeb meem tau txheeb xyuas sai sai - nws tsis yog qhov teeb meem ntawm cov cuab yeej siv, tab sis yog ib qho kev sib tw uas cuam tshuam nrog cov txheej txheem tsis xws li cov khoom siv, cov phaj cua sov, cov raj cua sov, thiab cov phaj hlau stainless.
Leveraging peb dual tus kheej li ob qho tib si "cov chaw tsim khoom hluav taws xob hluav taws xob" thiab "khoom noj khoom haus tshwj xeeb ua tshuab ua tshuab," peb pab neeg ua haujlwm tau sai sai tsim cov kev daws teeb meem:

Aluminium disc |
1. Lub brazing kua txheej ntawm lub aluminium disc yog tuab heev thiab tsis sib xws, 2. Cov kua brazing yog tuab heev |
|
1. Qhov piv ntawm cov kua brazing yuav tsum yog 1: 1: 7 (Brazing hmoov: tus neeg saib xyuas: dej) 2. Hloov nrog 2-nti txhuam, nce qhov txhuam hniav, thiab txo cov sij hawm txhuam hniav |
Ntau txheej txheej ntawm aluminium disc brazing hmoov yuav twv yuav raug hu ua deformation ntawm lub tshav kub phaj tom qab brazing |

SS. phaj
|
1. Cov roj ntau dhau ntawm qhov nto 2. Muaj teeb meem nrog lub xuas nrig ntaus pwm, ua rau tsis sib xws nto

1. Qhov piv ntawm lub tank tu yuav tsum yog 1: 3: 400 litres (acidic tu kua: tus neeg sawv cev: dej), soaked ntawm 70 degrees rau 5-10 feeb 2. Txhim kho qhov xuas nrig ntaus pwm.

1. Lub sijhawm ntxuav thiab so ntawm SS discs yuav tsum tsis txhob ntev dhau, txwv tsis pub nws yuav ua rau saum npoo oxide txheej puas thiab cov nto tig dub, 2. SS disc tu tus qauv: Tom qab ntxuav, yuav tsum tsis txhob muaj cov tee dej dai, thiab cov stains dej saum npoo yuav tsum tau ntws los 3. Tsis muaj teeb meem nrog kev ntxuav ntawm Al discs 4. Peb pom zoo kom ntub cov SS. phaj rau 5-10 feeb nyob rau hauv ib tug chemical kua pas dej ua ke. Thiab ntxuav cov roj uas ntab saum npoo dej nrog dej ntws hauv ib txwm dej pool

Thaum piav qhia txog cov teeb meem thiab kev daws teeb meem, peb cov engineers tau muab rau ntawm - qhov chaw cob qhia rau cov neeg siv khoom pab neeg, qhia lawv cov qauv kev ua haujlwm thiab cov txheej txheem tu txhua hnub. Tsis pub dhau ib lub lim tiam, tus nqi brazing tsis xws luag ntawm cov kab ntau lawm tau poob qis los ntawm 10% mus rau qis dua 1%. Qhov no txhais tau tias tus neeg siv khoom tau txais txiaj ntsig ncaj qha los ntawm:
1. Kev txo nqi tseem ceeb: Cov khoom pov tseg tau txo qis dua 90%, thiab cov nqi rov ua haujlwm tau raug tshem tawm zoo.
2. Muaj peev xwm nce ntxiv: Cov txheej txheem tsim khoom tau ua smoother, ua kom cov zis ntau ntxiv txhua hnub.
3. Kev nce qib hauv kev ua tau zoo thiab lub koob npe nrov: Cov khoom lag luam sib xws tau txhim kho tau zoo.
Vim li cas Davinci Tshuab tuaj yeem daws cov neeg siv khoom qhov teeb meem?
Vim rau Davinci, peb xa ntau tshaj li lub tshuab xwb. Peb cov txiaj ntsig tseem ceeb yog los ntawm peb qhov tshwj xeeb "tus tsim khoom + khoom tsim":
1. Kev tshaj lij qhov tob hauv kev tsim khoom: Peb peb tus kheej yog cov kws tshaj lij kev lag luam ntawm cov khoom siv hluav taws xob hluav taws xob thiab cov khoom siv hluav taws xob tag nrho. Peb nkag siab txhua qhov kev mob tshwm sim hauv kev tsim khoom - uas cov khoom siv tau zoo tshaj plaws, qhov kub thiab txias nkhaus sib npaug ntawm lub zog thiab qhov tsos, thiab qhov kev tsim kho zoo li cas tuaj yeem tiv thaiv kev txias txias. Qhov "txoj kev paub hauv paus," sau los ntawm ntau lab ntawm cov khoom, yog ncaj qha nkag mus rau hauv peb cov khoom tsim thiab kev debugging qauv.
Kev pabcuam ceev hauv paus hauv kev txawj ntse: Peb nkag siab tus nqi ntawm cov kab ntau lawm downtime. Yog li ntawd, peb qhov kev cog lus rau kev pabcuam yog "kev teb sai, tshem tawm qhov teeb meem." Peb tsis yog xa cov kws kho khoom siv xwb; peb kuj xa cov txheej txheem engineers uas nkag siab txog kev tsim khoom, kom ntseeg tau tias qhov kev daws teeb meem yog qhov systemic thiab ntev - kav ntev.
3. Tus Neeg Siv Khoom -Centric Cost Perspective: Peb ib txwm xav txog cov teeb meem los ntawm qhov kev xav ntawm peb cov neeg siv khoom cov nqi tsim khoom tag nrho. Tus nqi ntawm cov cuab yeej zoo tshaj plaws tsis yog nyob rau hauv nws tus nqi qis, tab sis hauv nws lub peev xwm los txo cov khoom pov tseg, txhim kho cov txiaj ntsig, thiab ua kom ruaj khov. Peb lub hom phiaj yog kom txo peb cov neeg siv khoom cov nqi tsim khoom los ntawm kev daws teeb meem uas suav nrog "cov khoom siv + txheej txheem + kev cob qhia."
Yog tias koj tab tom nrhiav rau lub rhaub dej kub, cov khoom siv me me, lossis lub tshuab brazing, thaum xaiv tus neeg muag khoom, xav nug peb cov lus nug no:
1. Lawv puas to taub tag nrho cov txheej txheem tsim khoom ntawm kuv cov khoom?
2. Lawv puas tuaj yeem muab cov kev daws teeb meem uas sib koom ua ke nrog cov khoom siv thiab kev tsim khoom thaum muaj teeb meem nyuaj?
3. Puas yog lawv cov kev pabcuam yog tsom rau "kev daws teeb meem tam sim" lossis "ua kom zoo rau kuv lub sijhawm ntev - cov khoom tsim tawm thiab cov nqi"?
Ntawm Davinci, peb cov lus teb yeej ib txwm meej: peb muag qhov tseeb thiab kev tsim khoom uas tau raug pov thawj los ntawm peb tus kheej cov khoom, thiab qhov ntawd tuaj yeem txo koj cov nqi thiab ua kom muaj txiaj ntsig zoo. Peb tsis yog tsuas yog koj cov khoom siv brazing, tab sis kuj yog kev txuas ntxiv ntawm koj pab neeg tsim khoom cov kws tshaj lij thiab tus khub hauv koj txoj kev ua kom zoo
