I. Kev Taw Qhia

Nrog rau kev txhim kho ntawm kuv lub teb chawssemiconductorthiab cov lag luam tseem ceeb, daim ntawv thov ntawmcov kav dej roj uas muaj cov khoom siv siabtab tom nthuav dav zuj zus. Cov lag luam xws li semiconductors, electronics, tshuaj, thiab zaub mov siv cov kav dej roj uas muaj cov roj ntshiab ntau yam. Yog li ntawd, kev siv cov kav dej roj uas muaj cov roj ntshiab kuj tseem ceeb rau peb.

2. Scope ntawm daim ntawv thov

Cov txheej txheem no feem ntau yog tsim rau kev teeb tsa thiab kev sim cov kav dej roj hauv cov chaw tsim khoom siv hluav taws xob thiab semiconductor, thiab kev vuam cov kav dej roj stainless hlau nyias-walled. Nws kuj tseem tsim nyog rau kev tsim cov kav dej huv hauv cov chaw tsim tshuaj, khoom noj thiab lwm yam.

3. Txoj cai txheej txheem

Raws li cov yam ntxwv ntawm qhov project, kev tsim kho ntawm qhov project no muab faib ua peb kauj ruam. Txhua kauj ruam yuav tsum tau ua kom zoo thiab huv si. Kauj ruam thawj zaug yog kev npaj ua ntej ntawm cov kav dej. Txhawm rau kom ntseeg tau tias muaj kev huv si, kev npaj ua ntej ntawm cov kav dej feem ntau yog ua tiav hauv chav ua ntej 1000 theem. Kauj ruam thib ob yog kev teeb tsa ntawm qhov chaw; Kauj ruam thib peb yog kev sim system. Kev sim system feem ntau sim cov hmoov av, cov dej noo, cov pa oxygen, thiab cov hydrocarbon hauv cov kav dej.

4. Cov ntsiab lus tseem ceeb ntawm kev tsim kho

(1) Kev npaj ua ntej kev tsim kho

1. Npaj cov neeg ua haujlwm thiab npaj cov tshuab thiab cov khoom siv siv hauv kev tsim kho.

2. Tsim ib chav tsev uas tau ua tiav lawm nrog qib kev huv ntawm 1000.

3. Tshuaj xyuas cov duab kos ntawm kev tsim kho, npaj cov phiaj xwm tsim kho raws li cov yam ntxwv ntawm qhov project thiab cov xwm txheej tiag tiag, thiab ua cov lus qhia txog kev siv tshuab.

(2) Kev tsim kho ua ntej ntawm cov kav dej

1. Vim yog qhov kev huv si siab uas xav tau rau cov kav dej roj uas muaj kev ntshiab siab, txhawm rau kom txo qhov kev vuam ntawm qhov chaw teeb tsa thiab xyuas kom meej tias muaj kev huv si, kev tsim kho kav dej yog ua ntej prefabricated hauv chav prefabricated 1000-theem. Cov neeg ua haujlwm tsim kho yuav tsum hnav khaub ncaws huv si thiab siv cov tshuab thiab cov cuab yeej yuav tsum khaws cia kom huv si, thiab cov neeg ua haujlwm tsim kho yuav tsum muaj kev nkag siab zoo txog kev huv si kom txo qis kev ua qias tuaj ntawm cov kav dej thaum lub sijhawm tsim kho.

2. Txiav Yeeb Nkab. Kev txiav yeeb nkab siv cov cuab yeej txiav yeeb nkab tshwj xeeb. Lub ntsej muag kawg txiav yog perpendicular rau txoj kab nruab nrab ntawm cov yeeb nkab. Thaum txiav yeeb nkab, yuav tsum tau ua kom tsis txhob muaj hmoov av thiab cua sab nraud ua rau sab hauv ntawm cov yeeb nkab puas tsuaj. Cov ntaub ntawv yuav tsum tau muab faib ua pawg thiab muab tus lej los pab txhawb kev vuam ua pawg.

3. Vuam yeeb nkab. Ua ntej vuam yeeb nkab, cov kev pab cuam vuam yuav tsum tau muab tso ua ke thiab muab tso rau hauv lub tshuab vuam tsis siv neeg. Cov qauv vuam sim tsuas yog tuaj yeem vuam tom qab cov qauv tau tsim nyog. Tom qab ib hnub ntawm kev vuam, cov qauv tuaj yeem vuam dua. Yog tias cov qauv tau tsim nyog, cov txheej txheem vuam yuav tseem tsis hloov pauv. Nws khaws cia rau hauv lub tshuab vuam, thiab lub tshuab vuam tsis siv neeg ruaj khov heev thaum vuam, yog li qhov zoo ntawm kev vuam kuj tsim nyog. Qhov zoo ntawm kev vuam yog tswj los ntawm lub microcomputer, uas txo qhov cuam tshuam ntawm tib neeg rau qhov zoo ntawm kev vuam, txhim kho kev ua haujlwm zoo, thiab tsim cov vuam zoo.

4. Cov txheej txheem vuam

(3) Kev teeb tsa hauv tsev

1. Kev teeb tsa cov kav dej roj uas muaj cov roj ntshiab siab yuav tsum huv si thiab huv si, thiab cov neeg teeb tsa yuav tsum hnav hnab looj tes huv si.

2. Qhov kev teeb tsa ntawm cov brackets yuav tsum ua raws li cov qauv tsim ntawm cov duab kos, thiab txhua qhov chaw ruaj khov yuav tsum tau npog nrog lub tes tsho roj hmab tshwj xeeb rau cov yeeb nkab EP.

3. Thaum cov kav dej uas tau ua tiav lawm raug thauj mus rau qhov chaw, lawv tsis tuaj yeem raug tsoo lossis taug kev rau, thiab lawv kuj tsis tuaj yeem muab tso ncaj qha rau hauv av. Tom qab muab cov brackets tso rau, cov kav dej yuav raug lo tam sim ntawd.

4. Cov txheej txheem vuam kav dej hauv qhov chaw zoo ib yam li cov uas nyob rau theem prefabrication.

5. Tom qab vuam tiav lawm thiab cov neeg ua haujlwm tau tshuaj xyuas cov qauv sib koom ua ke thiab cov sib koom ua ke ntawm cov kav dej kom tsim nyog, muab daim ntawv lo rau ntawm qhov sib koom ua ke thiab sau cov ntaub ntawv vuam.

(4) Kev sim tshuab

1. Kev kuaj xyuas lub kaw lus yog kauj ruam kawg hauv kev tsim cov roj uas muaj cov roj ntshiab. Nws yog ua tiav tom qab kev sim siab ntawm cov kav dej thiab kev ntxuav tiav lawm.

2. Cov roj siv rau kev kuaj xyuas lub cev yog cov roj tsim nyog. Qhov huv, cov pa oxygen, cov dej noo thiab cov hydrocarbons ntawm cov roj yuav tsum ua tau raws li qhov yuav tsum tau ua.

3. Lub cim qhia no raug kuaj los ntawm kev sau cov roj uas tsim nyog rau hauv cov kav dej thiab ntsuas nws nrog lub cuab yeej ntawm qhov hluav taws xob. Yog tias cov roj uas raug cua tawm ntawm cov kav dej yog tsim nyog, nws txhais tau tias lub cim qhia ntawm cov kav dej yog tsim nyog.

5. Cov Khoom Siv

Cov kav dej roj uas muaj cov pa roj huv siab feem ntau siv cov kav hlau stainless hlau nyias-phab ntsa raws li cov txheej txheem xav tau ntawm cov txheej txheem ncig, feem ntau yog 316L (00Cr17Ni14Mo2). Muaj peb yam khoom sib xyaw ua ke: chromium, nickel, thiab molybdenum. Qhov muaj chromium txhim kho qhov kev tiv thaiv corrosion ntawm stainless hlau hauv oxidizing media thiab tsim ib txheej ntawm chromium-nplua nuj oxide zaj duab xis; thaum qhov muaj molybdenum txhim kho qhov kev tiv thaiv corrosion ntawm stainless hlau hauv cov txheej txheem tsis-oxidizing. Kev tiv thaiv corrosion; Nickel yog ib qho khoom tsim ntawm austenite, thiab lawv qhov muaj tsis tsuas yog txhim kho qhov kev tiv thaiv corrosion ntawm hlau, tab sis kuj txhim kho cov txheej txheem kev ua tau zoo ntawm hlau.
