Plaub, dab tsi yog qhov teeb meem ntawm kev siv cua txias cov kav dej? Yuav daws lawv li cas?
1. Copper tube to:
Copper tube leakage yog qhov ua rau tuag taus ntawm cov cua txias. Thaum xau, cov tub yees ntawm lub tshuab cua txias yuav dhau, thiab lub tshuab cua txias yuav ua tsis tiav vim tsis muaj cua sov hloov nruab nrab. Yog vim li cas rau tooj liab raj xau yog qhov nyuaj. Cov hauv qab no yog cov laj thawj feem ntau rau kev xau.
(1) Manufacturing yog vim li cas:
① Eddy tam sim no tsis pom qhov tsis txaus ntseeg. GB qhia tias cov raj tooj liab yuav tsum yog 100% eddy tam sim no qhov teeb meem nrhiav pom, thiab qhia txog txoj kab uas hla ntawm cov khoom tsis xws luag (los ntawm qhov) ntawm cov qauv raj siv los ntsuas qhov ntsuas qhov tsis zoo los xyuas kom meej qhov rhiab heev ntawm eddy tam sim no qhov teeb meem nrhiav pom thiab tiv thaiv ntau yam tsis xws luag. nco. Qhov kev xav tau no tuaj yeem lav tau tag nrho hauv cov chaw ua haujlwm loj tooj liab tsis tu ncua, vim tias qhov tsis txaus ntseeg yog kev tshawb nrhiav online. Qhov online eddy tam sim no qhov teeb meem nrhiav kom paub tseeb tias txhua qhov ntev ntawm lub raj yog eddy tam sim no kuaj, uas yog 100% qhov tsis pom kev. Qee lub tuam txhab tooj liab tsis zoo li qhov no, lossis tsis ua qhov ntsuas qhov tsis txaus ntseeg tam sim no, lossis siv tus qauv qis eddy tam sim no flaw detectors rau random tshuaj xyuas. Nyob rau hauv txoj kev no, lub raj tooj liab muaj qhov tsis xws luag uas dhau ntawm tus qauv thiab tsis tuaj yeem pom lossis tsis pom, ua rau lub tshuab cua txias kom xau thaum tus neeg siv khoom siv;
② Lub eddy tam sim no qhov teeb meem nrhiav pom qhov tsis xws luag, tab sis lub raj tooj liab nto tsis raug cim lossis cov cim tsis raug lossis tsis meej. Nyob rau hauv cov txheej txheem ntawm kev tsim cov raj tooj liab, qhov tsis xws luag tau kuaj pom los ntawm eddy tam sim no flaw detection yuav tsum tau npog nrog tus cwj mem ntawm qhov tsis xws luag uas dhau tus qauv, kom tus neeg siv tuaj yeem tshem tawm cov raj tooj liab tsis zoo thaum siv. Txawm li cas los xij, vim tsis txaus adhesion ntawm tus cwj mem xaiv los ntawm cov chaw tsim khoom thaum lub sijhawm tsim khoom, kev hloov kho tsis raug ntawm rab phom inkjet, tsis tiav ziab, thiab fading ntawm tus number case thaum raug kub, tus neeg siv tsis tuaj yeem xaiv cov khoom siv. qhov tsis xws luag pom los ntawm eddy tam sim no flaw detection thaum siv. Thaum siv lub raj tooj liab tsis zoo hauv lub tshuab cua txias, nws yuav ua rau muaj qhov tsis zoo.
(2) Yog vim li cas rau cov neeg siv:
① Kev siv tsis raug ntawm cov hlab ntsha tsis raug kuaj pom los ntawm qhov tsis txaus ntseeg tam sim no. Raws li kev tsim cov raj tooj liab ib txwm muaj, lub raj tooj liab eddy tam sim no qhov tsis txaus ntseeg tsis yog tsuas yog cim cov cim kev puas tsuaj ntawm txhua lub kauj, tab sis kuj pleev xim rau qhov chaw puas tsuaj nrog cov cim dub kom cov neeg siv tuaj yeem txheeb xyuas thiab xaiv qhov "dub tube" thaum siv. Cov tuam txhab cua txias thiab tub yees yuav tsum piav qhia qhov no kom meej rau cov neeg ua haujlwm, tshwj xeeb tshaj yog cov neeg ua haujlwm tshiab, txhawm rau tiv thaiv cov kav dej puas los ntawm kev teeb tsa ntawm cov tshuab cua txias thiab cov tub yees. Peb tau pom qhov teeb meem no ntau zaus thaum peb nkag mus tob rau hauv cov neeg siv kev pabcuam. Qee tus neeg ua haujlwm tau nug peb tias muaj dab tsi tshwm sim rau cov xim dub ntawm cov yeeb nkab, thiab qee qhov kev txiav txim siab tsis tsim nyog thiab pom tias nws yog qhov tseeb vim tias "dub yeeb nkab" tau teeb tsa rau ntawm cov khoom uas ua rau lub tshuab cua txias thiab lub tub yees txias.
② Cov teeb meem ua haujlwm. Nyob rau hauv tus txheej txheem ntawm kev tsim ob pab kiag li lawm, lub tshuab cua txias lub ntsiab yeeb nkab yuav tsum mus los ntawm cov kev sib txuas ntawm dabtsi yog khoov, expanding, expanding, thiab vuam.
③ Cov dej ntws los ntawm kev vuam tsis zoo. Tom qab cov yeeb nkab tooj liab tau muab tso rau hauv cov ntawv txhuas perforated, cov kav dej yuav tsum tau txuas nrog, thiab lub luj tshib me me yuav tsum tau txuas rau lawv. Txhawm rau ua kom qhov kev sib txuas ruaj khov, thaum lub sij hawm tsim khoom, lub luj tshib me me yog welded rau cov yeeb nkab tooj liab nrog solder. Txoj kev vuam yog muab faib ua phau ntawv thiab tsis siv neeg. Thaum lub sij hawm welding, vim qhov zoo ntawm cov khoom siv, kev nthuav dav ntawm cov yeeb nkab tooj liab, thiab cov khoom txawv teb chaws ntawm qhov chaw vuam, cov vuam tsis muaj zog, ua rau lub vuam siv hluav taws xob, ua rau cov dej xau.
2. Kev tawg ntawm cov kav dej tooj liab:
Cov kab nrib pleb hauv cov kav dej tooj liab feem ntau yog tsom rau hauv cov txheej txheem nthuav dav thiab nthuav dav ntawm cov kav dej tooj liab. Qhov xwm txheej tawg yog qhia hauv daim duab 1. Hauv kev tsim khoom ntawm ob lub cuab yeej, kev nthuav dav thiab nthuav dav ntawm cov raj tooj liab yog cov txheej txheem txuas ntxiv, uas feem ntau ua tiav hauv ib txheej txheem. Muaj ntau qhov laj thawj rau kev tawg ntawm cov raj tooj liab, thiab cov laj thawj tseem ceeb yog raws li hauv qab no:
① Qhov zoo ntawm lub raj tooj liab nws tus kheej. Cov laj thawj rau qhov zoo ntawm lub raj tooj liab nws tus kheej tuaj yeem muab faib ua qhov tsis xws luag sab nraud, sab hauv nto khawb, thiab sab hauv oxidation. Thaum lub sij hawm txias ua deformation ntawm lub raj tooj liab thaum lub sij hawm expansion thiab expansion, nto yog elongated los ntawm tensile kev nyuaj siab. Thaum muaj qhov sib sib zog nqus khawb ntawm sab nrauv ntawm lub raj tooj liab, qhov txheej txheej ntawm lub raj tooj liab tsis tuaj yeem tiv taus qhov kev ntxhov siab ntawm qhov tensile, uas ua rau muaj qhov tshwm sim rub tawm, uas yog qhov tawg ntawm sab nrauv ntawm lub raj tooj liab uas peb pom. . Cov txheej txheem tawg uas tshwm sim los ntawm khawb ntawm qhov chaw sab hauv ntawm lub raj tooj liab zoo ib yam li cov txheej txheem tawg uas tshwm sim los ntawm khawb ntawm qhov chaw sab nrauv. Thaum lub puab nto ntawm lub raj tooj liab yog oxidized, kev sib txhuam quab yuam nyob rau hauv lub puab nto ntawm lub oxidized tooj liab raj yog txawv los ntawm uas nyob rau hauv lub puab nto ntawm lub unoxidized tooj liab raj thaum lub sij hawm nthuav, ua rau inconsistent lengths ntawm lub qis piers ntawm tooj liab raj. ntawm tib qhov ntev. Thaum nthuav dav, lub raj tooj liab nrog ib qho me me ntawm cov piers qis txuas mus rau qhov ntev ntev, ua rau kev nthuav dav thiab tawg.
Daim duab 1: Ib feem tawg ntawm lub tshuab cua txias cov raj tooj liab
② Yog vim li cas rau cov neeg siv. Thaum siv cov raj tooj liab, lawv feem ntau ncaj thiab txiav kom loj. Txiav feem ntau yog ua los ntawm chipless txiav. Qhov saum npoo ntawm cov raj tooj liab yog qhov muag muag tom qab kev kho cua sov. Thaum txiav tsis muaj chips, yog tias lub cutter tsis zoo los yog lub cutter loj dhau lawm, lub raj tooj liab yuav txo qis ntau dhau los yog muaj ntau cov burrs, tsim qhov chaw nres nkoj flash thiab chaw nres nkoj hardening, uas yuav ua rau tawg thaum nthuav. Lub tshav kub exchanger yog tsim los ntawm ntau "U"-zoo li lub raj. Qhov kev xav tau ntawm qhov ntev ntawm txhua "U"-shaped raj thiab qhov ntev ntawm ob qhov kawg ntawm txhua "U"-shaped raj yog siab heev. Thaum khoov lub "U"-shaped raj, vim yog cov khoom siv lossis kev hloov kho, qhov ntev ntawm txhua "U"-shaped raj thiab qhov ntev ntawm ob qhov kawg ntawm txhua "U"-zoo li lub raj yog sib txawv heev (ntau dua 2 hli). Yog li ntawd, thaum nthuav dav, qhov chaw nres nkoj yuav ntev dhau lawm thiab lub raj tooj liab yuav ntev dhau lawm, ua rau qhov nthuav dav heev thiab tawg.
3. Wrinkling thiab tawg ntawm khoov raj:
Wrinkling thiab tawg ntawm cov hlab tooj liab (Daim duab 2, daim duab 3) tshwm sim nyob rau hauv tus txheej txheem ntawm ua "U"-zoo li tus hlab. Cov raj tooj liab feem ntau tau muab pov tseg hauv cov txheej txheem no.
