Kev Tiv Thaiv & Kev Kho Cov Npauj Npaim Valve Corrosion

Dab tsi yog corrosion ntawmnpauj npaim li qub?

Corrosion ntawm npauj npaim li qub feem ntau yog to taub raws li kev puas tsuaj ntawm cov khoom siv hlau ntawm lub valve nyob rau hauv qhov kev txiav txim ntawm tshuaj lom neeg los yog electrochemical ib puag ncig. Txij li thaum qhov tshwm sim ntawm "corrosion" tshwm sim nyob rau hauv kev sib cuam tshuam ntawm cov hlau thiab ib puag ncig ib puag ncig, yuav ua li cas cais cov hlau los ntawm ib puag ncig ib puag ncig lossis siv cov khoom siv tsis yog xim hlau ntau dua yog qhov tseem ceeb ntawm kev tiv thaiv corrosion. Lub cev ntawm lubnpauj npaim valve(nrog rau lub valve cover) occupies feem ntau ntawm qhov hnyav ntawm lub valve thiab yog nyob rau hauv kev sib cuag nrog lub nruab nrab, yog li ntawd lub npauj npaim valve feem ntau xaiv los ntawm lub cev khoom.

Muaj tsuas yog ob hom valve lub cev corrosion ntawmnpauj npaim li qub, uas yog tshuaj corrosion thiab electrochemical corrosion. Nws tus nqi corrosion yog txiav txim siab los ntawm qhov kub thiab txias, siab, tshuaj lom neeg ntawm qhov nruab nrab, thiab corrosion kuj ntawm valve lub cev khoom. Tus nqi corrosion tuaj yeem muab faib ua rau qib:

1. Ua tiav corrosion tsis kam: tus nqi corrosion yog tsawg dua 0.001 hli / xyoo;

2. Kev tiv thaiv corrosion heev: corrosion tus nqi 0.001-0.01 hli / xyoo;

3. Corrosion kuj: corrosion tus nqi 0.01-0.1 hli / xyoo;

4. High corrosion kuj: corrosion tus nqi 0.1-1.0 hli / xyoo;

5. Tsis zoo corrosion kuj: corrosion tus nqi 1.0-10 mm / xyoo;

6. Tsis-corrosion tsis kam: tus nqi corrosion yog ntau dua 10 hli / xyoo.

Yuav ua li cas tiv thaiv corrosion ntawmnpauj npaim li qub?

Kev tiv thaiv corrosion ntawm lub valve lub cev ntawm npauj npaim valve feem ntau yog vim kev xaiv cov ntaub ntawv raug. Txawm hais tias cov ntaub ntawv ntawm kev tiv thaiv corrosion yog nplua nuj heev, nws tsis yooj yim rau xaiv qhov yog, vim hais tias qhov teeb meem ntawm corrosion yog heev complex, piv txwv li, sulfuric acid yog heev corrosive rau hlau thaum lub concentration yog tsawg, thiab thaum lub concentration siab, nws ua rau cov hlau tsim ib tug passivation zaj duab xis, uas yuav tiv thaiv corrosion; Hydrogen tsuas yog pom tias muaj corrosive heev rau hlau ntawm qhov kub thiab txias, thiab kev ua haujlwm corrosion ntawm cov roj chlorine tsis loj thaum nws qhuav, tab sis qhov kev ua haujlwm corrosion muaj zog heev thaum muaj qee cov av noo, thiab ntau cov ntaub ntawv siv tsis tau. Qhov nyuaj ntawm kev xaiv valve lub cev cov ntaub ntawv yog tias peb tsis tuaj yeem xav txog cov teeb meem corrosion, tab sis kuj tseem xav txog yam xws li siab thiab kub tsis kam, seb nws puas tsim nyog, thiab seb nws puas yooj yim rau kev yuav khoom. Yog li koj yuav tsum ua tib zoo mloog.

1. Qhov thib ob yog siv hauv ob sab phlu ntsuas, xws li txhuas, txhuas, engineering yas, roj hmab ntuj thiab ntau yam hluavtaws roj hmab. Yog hais tias qhov nruab nrab tej yam kev mob tso cai, qhov no yog ib txoj kev txuag.

2. Thib peb, thaum lub siab thiab kub tsis siab, cov khoom tseem ceeb ntawm fluorine-lined npauj npaim valve feem ntau tuaj yeem ua tau zoo heev los tiv thaiv corrosion.

3. Tsis tas li ntawd, sab nrauv ntawm lub valve lub cev kuj corroded los ntawm cov cua, thiab cov khoom siv hlau feem ntau tiv thaiv los ntawm npib tsib xee plating.

TWS yuav sai sai no tshaj tawm cov khoom tshiab los tiv thaiv corrosion, npog tag nrho cov kev daws teeb meem xws linpauj npaim li qub, rooj vag li qub, check li qubthiab pob li qub, lwm. Cov khoom lag luam no tau txais cov cuab yeej siv siab tshaj corrosion kuj thiab cov txheej txheem kho cov khoom siv tshwj xeeb kom muaj kev sib khi zoo heev thiab kev ua haujlwm ruaj khov hauv kev ua haujlwm hnyav. Peb tau cog lus los muab cov neeg siv khoom nrog cov khoom lag luam ruaj khov valve, txuas ntxiv kev pab cuam lub neej ntawm cov khoom siv, txo cov nqi tu txhua lub neej.ncualub voj voog, thiab pab cov neeg siv khoom kom ua tiav qhov kev txiav txim siab yuav khoom ntau dua.
