Tuam Tshoj Slurry Twj Tso Khoom Siv Xaiv lub Hoobkas thiab cov chaw muag khoom | YAAO

Nyob rau hauv lub twj tso kua mis slurry lub impeller thiab sab hauv ntawm lub casing yog ib txwm raug rau lub slurry thiab yuav tsum muaj kev tiv thaiv kev tiv thaiv kev tiv thaiv kev hnav.
"Kev xaiv cov khoom siv rau lub zog thiab cov thom khwm yog qhov tseem ceeb xws li kev xaiv twj tso kua mis nws tus kheej!"

Muaj peb qhov sib txawv uas tsim kev coj hauv lub twj tso kua mis:

Puas,Yaig,Kev xeb

Puas Muaj

Nws muaj peb yam loj ntawm abrasion:
Hauv cov hlais hlais peb muaj qhov sib tsoo thiab qis kev ntxhov siab.
Abrasion tus nqi yog nyob ntawm qhov loj me thiab qhov nyuaj.

Kev tsim txom tsuas yog tshwm sim hauv ob thaj chaw hauv lub twj tso kua mis:
1.Txiav impeller thiab nyob ruaj ruaj inlet.
2. Nruab nrab ntawm lub tes tsho loj thiab ntim khoom ruaj ruaj.

Yaig

Qhov no yog qhov tseem ceeb hnav nyob rau hauv cov twj tso kua mis. Qhov laj thawj yog tias qhov me me hauv cov slurry ntaus cov khoom nto ntawm ntau cov ces kaum.
Yaig hnav yog qhov hnyav nyob rau hauv qhov tsim los ntawm kev siv lub twj tso kua mis ua haujlwm li cas. Kev yaig hnav yog, feem ntau, qhov tsawg kawg nkaus ntawm BEP fl ow tus nqi, thiab nce nrog qhov qis dua li cov kev cuam tshuam ntau dua.
Rau cov laj thawj uas tsis nkag siab zoo, hnav khaub ncaws yuav tau nce ntau yog tias lub twj tso kua mis tso cai ua haujlwm ntawm "qaj"; uas yog, noj cua mus rau hauv cov yeeb nkab inlet.
Nws tau hais tias qhov no tuaj yeem yog vim cavitation, vim lub tshuab nqus pa qhov chaw tshee li huab cua nyob dhau ntawm lawv. Qhov no yog, txawm li cas los xij, qhov nyuaj yuav pom zoo raws li huab cua npuas feem ntau txwv qhov cavitation los ntawm kev tsiv mus rau qhov vapor kab noj hniav.
Muaj peb hom kev yaig:
Qhov cuam tshuam ntawm yaig ntawm lub twj tso kua mis:

Impeller

Tus impeller yog qhov cuam tshuam rau kev hnav (siab thiab qis) feem ntau yog nyob rau hauv lub qhov muag, ntawm lub caj pas sab shroud (A), thaum lub qes tig 90 °. Ntawm kev pib ntawm ntug kev vane (B).
Zawv zawg lub txaj thiab lub siab tsis tshua muaj kev cuam tshuam tshwm sim raws cov vanes ntawm tus impeller shrouds (C).
Cov hnab twb qhib lawm (sab hauv thiab qaum)
Cov tog hauv ib sab yog raug zawv zawg txaj thiab tsoo thiab sib tsoo puas.

Lub Neej

Lub tshuab raj yog yuav cuam tshuam rau kev cuam tshuam ntawm cov dej txiav. Zawv zawg lub txaj thiab lub siab tsis tshua muaj kev cuam tshuam coj tshwm sim hauv qhov seem ntawm lub sijhawm.
Corrosion:
Kev txhim kho cov xeb (thiab tshuaj lom neeg) ntawm cov ntub dej hauv cov twj tso kua mis Slurry yog ib qho xwm txheej nyuaj rau ob qho tib si hlau thiab cov khoom siv elastomer.
Txog kev taw qhia, tshuaj lom neeg cov tshuaj lom rau cov hlau thiab cov khoom siv elastomer tau muab rau ntawm hauv qab thiab hauv ntu Cov Khoom Siv Khoom Siv Khoom.

Hnav kev tiv thaiv - cov kev xaiv dab tsi?

Muaj qee qhov kev xaiv loj hauv kev xaiv hnav tiv thaiv ntawm cov twj tso kua mis:
Impeller thiab casing hauv Hard Hlau hauv ntau cov hlau ntawm cov hlau dawb thiab hlau.
Ua rau hauv cov elastomer thiab cov nplais tiv thaiv los ntawm elastomer liners. Elastomers zoo li qub roj hmab hauv ntau yam zoo lossis polyurethane.
Kev sib txuas ntawm impeller ntawm cov hlau nyuaj thiab elastomer-lined casings.

Kev xaiv ntawm cov ntaub ntawv coj los hnav

qhov kev xaiv ntawm cov khoom hnav yog qhov sib npaug ntawm kev ua haujlwm rau hnav thiab tus nqi ntawm qhov hnav.
Muaj ob lub tswv yim los tiv thaiv kev hnav khaub ncaws:
Cov khoom siv coj mus yuav tsum nyuaj rau nws tiv taus kev txiav txim siab ntawm kev cuam tshuam cov khib nyiab! lossis Kev coj cov khoom siv yuav tsum muaj ywj siab kom tuaj yeem nqus tau cov poob siab thiab rov ua dua ntawm cov nplais!

Cov tsis rau kev xaiv

Kev xaiv ntawm kev coj ntawm qhov yog feem ntau raws li cov lus hauv qab no:

Cov khoom loj (xim SG, zoo thiab tawv)
Slurry qhov kub thiab txias
pH thiab tshuaj lom neeg
impeller ceev
