Vim li cas cov yeeb nkab txhuam hniav thiaj siv tau rau cov yeeb nkab khoom noj?

Tus yuam sij rau kev ua cov yeeb nkab txhuam hniav rau cov khoom noj yog nyob rau hauv qhov tseeb tias cov txheej txheem txhuam hniav hais txog
ob qhov teeb meem tseem ceeb tshaj plaws hauv kev nyab xeeb zaub mov: kev loj hlob ntawm cov kab mob me me thiab cov khoom seem ntxuav.
Nws ua rau sab hauv ntawm cov yeeb nkab sib txuas du heev, tsis muaj qhov chaw rau cov kab mob zais,
thaum tseem txhim kho kev tiv thaiv corrosion kom ntseeg tau tias cov kua dej huv.
Qhov muaj cov yeeb nkab no tuaj yeem ua kom ntseeg tau los ntawm plaub yam.
Tiv thaiv kev loj hlob ntawm cov kab mob me me
Qhov tseem ceeb tshaj plaws rau cov yeeb nkab khoom noj yog tias phab ntsa sab hauv yuav tsum du heev,
tsis muaj qhov chaw me me rau cov av thiab cov kab mob sib sau ua ke.
Qhov tiav ntawm qhov chaw yog siab heev: cov yeeb nkab khoom noj khoom haus feem ntau xav tau qhov roughness ntawm phab ntsa sab hauv (Ra) tsawg dua 0.8 μm,
thiab cov uas tau electrolytic polishing tuaj yeem ua tiav Ra ​​≤ 0.4 μm.
Qhov du zoo li daim iav no ua rau cov kab mob thiab cov av tsis lo thiab loj hlob tau.
Tshem tawm cov ces kaum tuag: Kev txhuam ua ke nrog kev vuam thiab kev sib txuas siab tshem tawm cov ces kaum tuag
thiab cov qhov tawg hauv cov kav dej, tiv thaiv cov khoom seem.
2. Xyuas kom yooj yim ntxuav thiab tua kab mob.
Cov kab ntau lawm zaub mov raug ntxuav kom huv (CIP) thiab ua kom tsis muaj kab mob (SIP) txhua hnub,
thiab cov yam ntxwv ntawm cov yeeb nkab ncaj qha txiav txim siab qhov ua tau zoo ntawm kev ntxuav.
Nws txhawb nqa kev ntxuav hauv qhov chaw: qhov chaw du heev ua rau cov tshuaj ntxuav kov tau
thiab ntxuav cov khoom seem yam tsis muaj kev cuam tshuam, xyuas kom tsis muaj kev ntxuav cov ces kaum tuag.
Nws txhawb nqa cov txheej txheem ntxuav hauv qhov chaw rau CIP (kev ntxuav hauv qhov chaw) thiab SIP (kev ua kom tsis muaj kab mob hauv qhov chaw).
Tiv thaiv "phab ntsa lo": tshwj xeeb tshaj yog rau cov kua dej khov xws li mis nyuj thiab kua txiv hmab txiv ntoo,
kev txhuam kom zoo tuaj yeem tiv thaiv kev tsim cov phab ntsa lo rau hauv cov yeeb nkab,
zam kev ua qias tuaj ntawm cov khoom lag luam vim lub sijhawm ntev thiab kev puas tsuaj.
3. Txhim kho kev ua haujlwm tiv thaiv corrosion
Cov khoom muaj kua qaub thiab alkaline uas kov tau zaub mov (xws li acetic acid thiab cov tshuaj ntxuav)
feem ntau cov kav dej yuav xeb. Tsim ib txheej passivation: Polishing feem ntau yog ua ke
nrog cov txheej txheem ntxuav kua qaub thiab passivation. Qhov no tuaj yeem tsim cov zaj duab xis chromium-nplua nuj oxide ntom ntom rau ntawm qhov chaw ntawm cov hlau tsis xeb,
tiv thaiv cov yeeb nkab fittings los ntawm xeb thiab yog li tshem tawm qhov kev pheej hmoo ntawm kev tsiv teb tsaws chaw ntawm cov hlau hnyav thiab cov khoom noj khoom haus.
Tshem tawm cov qhov tsis zoo ntawm qhov chaw: Kev txhuam hniav los yog kev txhuam hniav electrolytic tuaj yeem tshem tawm cov kab nrib pleb me me,
cov nplai oxide, thiab cov khoom me me (xws li cov tshuaj txhuam polishing) rau ntawm qhov chaw ntawm cov yeeb nkab,
uas feem ntau yog cov chaw pib ntawm kev xeb.
4. Cov Khoom Siv Huv Si thiab Kev Ua Raws Cai
Cov khoom siv hauv paus rau zaub mov: Cov yeeb nkab uas siv tau rau kev txhuam zaub mov yog ua los ntawm cov khoom siv hauv paus rau zaub mov lawv tus kheej,
feem ntau yog 304 lossis 316L stainless hlau, thiab ua tau raws li lub teb chaws tus qauv rau cov khoom sib piv ntawm cov hlau xws li GB 9684.
Cov txheej txheem ua raws li txoj cai: Tom qab txhuam, lawv kuj yuav tsum tau ua kom tsis muaj roj ntau
kev ntxuav kom tshem tawm cov roj seem thaum lub sijhawm ua haujlwm thiab yuav tsum tau kuaj xyuas los ntawm lub tshuab ntsuas roj kom paub tseeb tias lawv yuav
tsis txhob ua rau cov khoom noj muaj kuab paug.
