DINSEN Yeeb Nkabtsom mus rau kev lag luam pipeline. Nrog kev paub nplua nuj thiab thev naus laus zis siab heev, nws cov khoom suav nrog cov kav hlau ductile, cov kav hlau cam khwb cia (tseem hu ua SML yeeb nkab), cov khoom siv yeeb nkab thiab kev sib txuas thiab lwm yam, uas tau siv dav hauv kev tsim kho vaj tse, kev tsim kho, kev muab dej, tsev so, tshav dav hlau thiab lub zog. Nws yog tus muab kev daws teeb meem pipeline txhim khu kev qha rau ntau qhov project loj.
Cov txheej txheem tsim cov kav dej
1.Kev smelting raw khoom
Cov khoom siv raw hlau npua rau kev tsim cov kav dej thiab cov khoom siv.
Cov khoom siv ntxiv xav tau hlau No. 15 thiab cov kav dej xav tau hlau No. 20.
Daim duab hauv qab no yog lub cub hluav taws xob, uas siv hluav taws xob los ua kom cov hlau ci ua kub.
Npua Hlau
Lub Cub Hluav Taws Xob
2.Kev sib tsoo centrifugal
Hloov cov pwm yeeb nkab uas muaj txoj kab uas hla sib xws rau lub centrifuge ua ntej raws li qhov xav tau.
Cov hlau uas yaj lawm raug txhaj rau hauv lub pwm centrifuge uas tig ceev ceev los ntawm sab hauv mus rau sab nraud los ntawm txoj kab ntws.
Tus nqi ntawm cov hlau molten yog xam raws li lub cheeb ntawm cov yeeb nkab cam khwb cia.
Tom qab ua tiav thiab txias cov yeeb nkab lawm, yuav rub tawm ntawm cov pwm yeeb nkab, thiab tus neeg tshuaj xyuas zoo yuav xyuas seb nws zoo li cas thiab hnyav npaum li cas. Cov neeg tsim nyog yuav ua haujlwm ntxiv.
Cov pwm ntawm cov yeeb nkab loj dua 3 meters, uas yooj yim rau kev txiav cov khoom tsis sib xws ntawm lub taub hau lossis tus Tsov tus tw tom qab.
Centrifuge
3. Txiav yeeb nkab, tshuaj xyuas, thiab txhuam kom du
Tom qab xaiv cov kav dej uas tsim nyog, cov neeg ua haujlwm yuav txiav cov khoom uas tsis sib npaug ntawm lub taub hau thiab tus tw kom khaws qhov ntev ntawm cov kav dej ntawm 3m.
Tom qab txiav tiav lawm, yuav muaj kev tshuaj xyuas dua los xaiv cov kav dej uas tsis sib npaug ntawm phab ntsa thiab elliptical deformation kom yaj dua.
Kev txhuam yuav tsum tau txhuam ob sab hauv thiab sab nraud ntawm lub yeeb nkab kom ntseeg tau tias sab hauv thiab sab nraud du thiab yooj yim rau kev pleev xim tom qab.
Tshuab Sib Tsoo
4. Tshuaj tsuag sab hauv thiab sab nraud
Phab ntsa sab hauv ntawm cov yeeb nkab uas tau txhuam yuav tsum tau khaws cia kom du thiab huv. Tom qab ziab thiab cua sov, phab ntsa sab hauv raug kho nrog cov tshuaj tiv thaiv xeb, uas yog, txau nrog cov xim daj epoxy.
Tib qho kev ua haujlwm kuj tseem ua rau sab nraud, txau nrog xim epoxy xim av liab.
Lub Hoobkas yuav kuaj thiab kuaj xyuas cov khoom kom paub tseeb tias cov khoom ua tau raws li cov cai ntawm EN877.
5. Ziab, txiav, txau, ntim khoom
Tom qab txau cov xim sab hauv thiab sab nraud, cov yeeb nkab yuav qhuav kom ntseeg tau tias cov xim lo rau.
Tom qab ziab tas, cov neeg ua haujlwm yuav kho cov xim ntawm lub yeeb nkab, tshwj xeeb tshaj yog ob qho kawg, kom ntseeg tau tias cov xim npog thiab zoo nkauj.
Thaum kawg, cov yeeb nkab yuav raug txau nrog cov neeg siv khoom lub cim lag luam thiab ntim raws li tus neeg siv khoom tus cwj pwm.
Lub tshuab ziab khaub ncaws
Cov txheej txheem tsim khoom siv
1. Kev npaj pwm
Tam sim no DINSEN muaj pwm ntawm txhua tus qauv thiab cov lus qhia. Txhua zaus lub Hoobkas npaj ntau lawm, tus lej casting thiab batch hauv pwm yuav tsum tau hloov, thiab tom qab ntawd cov neeg ua haujlwm tuaj yeem pib ntau lawm tom qab tau txais pwm.
2. Kev nchuav tes, Kab tsim yeeb nkab tsis siv neeg
Cov neeg ua haujlwm muab cov pwm sab saud thiab sab hauv qab tso rau ntawm lub phaj tiaj tiaj, muab lub thawv xuab zeb tso rau ntawm nws, sau nrog xuab zeb, nias nws, thiab khawb nws kom tiaj tus. Tom qab ntawd lawv muab cov pwm sab saud thiab sab hauv qab ua ke thiab kho lawv, thiab tom qab nchuav cov hlau yaj, lawv tau tsim ua ib zaug xwb.
Txhua tus neeg ua haujlwm tuaj yeem tsim tau qhov nruab nrab ntawm 300KG ntawm cov yeeb nkab fittings ib hnub, vim tias kev hloov pwm ntau zaus tsis yog tsuas yog cuam tshuam rau lub Hoobkas lub sijhawm tsim khoom xwb tab sis kuj cuam tshuam ncaj qha rau cov neeg ua haujlwm cov zis.
Kab ntau lawm yeeb nkab tsis siv neeg, nchuav tes
Piv nrog rau cov txheej txheem xuab zeb casting ib txwm muaj, nws qhov tshwj xeeb tshaj plaws yog tias nws tuaj yeem txo qis kev siv cov neeg ua haujlwm thiab cov khoom siv, thiab ua kom muaj txiaj ntsig zoo tshaj plaws, xyuas kom meej tias cov khoom zoo ua tau raws li cov qauv thiab cov lus qhia tau sib koom ua ke, uas tuaj yeem txhim kho kev ua haujlwm ntau lawm thiab luv luv cov voj voog tsim khoom.
3. Kev sib tsoo tes
Raws li lub hauv paus ntawm kev ua kom pom tseeb qhov ntev sab nraud ntawm cov khoom, cov neeg ua haujlwm yuav tsum tshem tawm cov rooj vag, risers, flash, burrs thiab cov xuab zeb molding ntawm qhov chaw los ntawm kev sib tsoo. Qhov tsis muaj nqaij los ntawm kev tsis txaus casting, keyholes lossis xuab zeb ntxuav kuj yuav tsum tau kho. Xyuas kom meej tias cov khoom tsis huv ntawm qhov chaw ntawm casting huv si thiab polished ua ntej txau tom qab.
4. Sab nraud phab ntsa polishing,Kev sib tsoo phab ntsa sab hauv,Kev sib tsoo zoo
5. Pleev xim, hmoov txheej, ntim khoom
Kev pleev xim: Koj yuav tsum tau preheat cov yeeb nkab fittings rau 70-80 ℃ thiab tsuag xim epoxy.
Tshuaj tsuag hmoov: Koj yuav tsum tau preheat cov yeeb nkab fittings rau 180-200 ℃ ua ntej txau hmoov epoxy.
