Yuav ua li cas xaiv Diaphragm rau koj lub siab Transmitter

Xaiv txoj cai diaphragm cov khoom siv rau koj lub siab xa tawm yog ib kauj ruam tseem ceeb hauv kev ntsuas cov kev ntsuas yog qhov tseeb, ntev, thiab tag nrho kev ntseeg tau. Muab hais tias cov transmitters siab tau siv nyob rau hauv ntau cov ntawv thov kev lag luam thiab ib puag ncig, kev xaiv tshwj xeeb rau kev ua tau zoo rau kev ua tau zoo. Cov lus qhia no yuav pab koj rau kev xaiv diaphragm uas cuam tshuam, suav nrog cov kev ntsuas nruab nrab, cov kev ntsuas ib puag ncig, thiab cov ntsuas yuav tsum muaj tseeb.

1. Nkag siab txog cov khoom ntawm cov ntsuas ntsuas ntsuas

Thawj kauj ruam hauv Diaphragm xaiv yog kom nkag siab txog cov yam ntxwv ntawm cov kua dej lossis roj ntsuas. Cov yam ntxwv tseem ceeb los txiav txim siab suav nrog cov tshuaj lom neeg muaj pes tsawg leeg, ntsuas kub, viscosity, thiab corrosived ntawm nruab nrab. Cov xwm txheej ncaj qha rau cov khoom xaiv rau cov diaphragm.

Piv txwv li, yog tias ntsuas qhov nruab nrab yog cov xeb zoo, xws li hauv Saltwater lossis muaj qhov tseem ceeb los xaiv cov ntaub ntawv uas muaj cov khoom lag luam zoo dua. Cov ntaub ntawv xws li Hastelloy (Hastelloy c), titanium alloys, lossis tantalum yog cov kev xaiv zoo rau cov ntawv thov. Nov yog qee cov qauv ntawm cov khoom haum:

Hastelloy C: Haum rau kev ntsuas kub thiab ib puag ncig uas muaj phosphoric acid. Txawm li cas los xij, nws tsis pom zoo rau high-concentration sulfuric lossis nitric acid.

Titanium alloys: Zoo heev rau cov chaw ib puag ncig feem ntau tab sis yuav tsum tsis txhob siv rau hauv cov alkaline lossis hydrofluoric acid (HF) ib puag ncig.

TANTUM: paub rau nws lub siab tiv taus cov tshuaj uas muaj cov xeb, tshwj xeeb hauv kev ua haujlwm ib puag ncig ua haujlwm, tab sis nws zoo li yuav kim dua lwm cov kev xaiv.

2. Xaiv txoj cai diaphragm cov khoom

Cov khoom sib txawv ntawm cov ntaub ntawv sib txawv tau haum rau cov ntawv thov sib txawv raws li lawv txoj kev tiv thaiv kom hnav, corrosion, thiab qhov kub thiab txias. Ntawm no yog qhov kev tawg sai ntawm cov khoom siv thiab lawv siv cov xwm txheej:

Stainless hlau (316L): Qhov no yog ib qho uas feem ntau siv cov ntaub ntawv vim nws cov kev tiv thaiv corrosion zoo thiab tshuab zog. Nws yog tus nqi-ua haujlwm zoo rau feem ntau cov ntawv thov kev lag luam, suav nrog cov uas nyob hauv kev kho cov dej, ua zaub mov.

Hastellloy diaphragms: paub rau lawv cov kev tiv thaiv zoo tshaj plaws rau kev ua kom haum ib puag ncig, hastellloy diaphragms yog qhov zoo rau kev siv hauv acidic thiab cov xwm txheej hnyav. Txawm li cas los xij, lawv kim dua thiab tsis haum rau txhua qhov chaw tshuaj.

Titanium diaphragms: Titanium muab cov tshuav zoo ntawm corrosion tsis kam, lub zog, thiab qhov hnyav. Nws yog qhov zoo tshaj plaws rau feem ntau cov ntawv thov tsuas yog cov kev cuam tshuam HF (Hydrofluoric acid) lossis alkaline media.

TANTALUM DIAPHRAGMS: Muab cov kev tiv thaiv corrosion siab tshaj, tantalum feem ntau siv hauv cov chaw muaj kev sib luag. Txawm li cas los xij, nws tus nqi tsim nyog nws ntau kev siv rau kev lag luam uas muaj kev tiv thaiv corrosion yog qhov tseem ceeb.

Ceramic diaphragms (aluminium oxide lossis zirconium oxide): Cov no feem ntau siv hauv cov corrosive corrosive. Txawm li cas los xij, lawv muab qis dua cov lus ruaj khov piv rau cov hlau diaphragms thiab tej zaum yuav tsis haum rau cov ntawv thov kom ua tiav siab.

3. Xav txog ib puag ncig ib puag ncig

Cov kev ua haujlwm ib puag ncig uas koj lub siab xa cov kev ua haujlwm yuav cuam tshuam nrog kev xaiv diaphragm.

Piv txwv li, yog tias ntsuas nruab nrab muaj cov qib hydrogen high high hydrogen, ib qho kub-coated Diaphragm raug pom zoo los tiv thaiv hydrogen maj. Qhov no ua kom cov diaphragm tswj hwm nws kev ncaj ncees thiab tsis muaj kev txom nyem los ntawm kev tawg lossis ua tsis tiav vim muaj cov hydrogen.

Hauv ib puag ncig uas kub siab yog qhov kev txhawj xeeb (feem ntau yog 200 degree), tshwj xeeb kub dog dig zoo li cov teeb meem silicone, uas tuaj yeem ua rau kev ntsuas cov khoom tsis muaj tseeb. Cov ntaub ntawv xws li Inconel lossis Hastelloy muaj feem ntau siv nyob rau hauv cov ntawv thov kub siab no.

Hauv kev siv nrog huab siab lossis lub tshuab nqus tsev, cov tshuab nqus dej yuav tsum muaj zog kom tiv thaiv cov rog no yam tsis muaj kev puas tsuaj. Lub diaphragm thickness thiab cov khoom siv zog yog qhov kev txiav txim siab tseem ceeb ntawm no.

4. Precision Yuav Tsum Tau

Rau cov ntawv thov uas yuav tsum tau ntsuas qhov tseeb, nws yog qhov tseem ceeb los xaiv lub siab transmitter nrog lub siab ntsuas. Lub thickness thiab cov duab ntawm cov diaphragm ua si lub luag haujlwm tseem ceeb hauv kev ntsuas qhov ntsuas tau yog qhov tseeb tau. Ib daim nyias nyias diaphragm feem ntau muaj ntau dua thiab tuaj yeem muab cov sijhawm teb sai dua, tab sis nws yuav tsis yog li cov xwm txheej tsis ruaj khov.

5. Txhim kho thiab kho cov kev txiav txim siab

Thaum xaiv cov diaphragm, tseem xav txog qhov yooj yim ntawm kev teeb tsa thiab txij nkawm. Qee hom diaphragm yog yooj yim dua rau nruab thiab tuav tau ntau dua li lwm tus, uas tuaj yeem txuag lub sijhawm thiab cov nqi ua haujlwm. Tiaj tus diaphragm siab transmitters, piv txwv li siv hauv ntau daim ntawv thov vim tias lawv yooj yim rau nruab thiab tswj. Cov kev hloov tsheb no tuaj yeem ntsia tau rau hauv cov chaw nruj thiab tsis tshua muaj kev pab cuam.

6. Cov kev txiav txim siab tshwj xeeb rau cov ntawv thov tshwj xeeb

Hauv kev lag luam tshwj xeeb, xws li cov roj thiab roj, lossis cov qauv siv tshuaj, koj yuav tsum tau xaiv cov khoom siv tshwj xeeb dolphragm thiab cov haujlwm kom muaj kev nyab xeeb thiab ntseeg tau nyob hauv cov chaw ib puag ncig ntawd. Cov kev lag luam no feem ntau ua haujlwm nrog cov kua dej thiab roj av uas muaj qhov ntsuas kub heev, siab, lossis tshuaj lom neeg yuav tsum tau raws txoj kev tswj hwm nruj.

Piv txwv li, hauv cov khoom noj khoom haus thiab dej haus huv si cov ntaub ntawv uas ua raws cov qauv kev nyab xeeb (zoo li 316L stainless hlau) feem ntau yuav tsum tau ua. Cov ntaub ntawv no yuav tsum tau yooj yim ntxuav thiab tswj kom paub txog kev tu cev.
