Cov Hom Pipeline Linings Ntsuas Tau Los Ntawm Electromagnetic Flowmeters

1. Cov roj hmab Linings

1.1 Roj Hmab Ntuj

Cov roj hmab ntuj yog ib qho kev xaiv nrov rau cov kav dej hauv cov ntawv thov uas cov ntsuas nruab nrab tsis yog corrosive thiab muaj qhov kub qis. Nws muaj kev tiv thaiv zoo heev, uas ua rau nws haum rau cov kua uas yuav muaj cov khoom me me, xws li qee hom dej khib nyiab lossis cov slurries nrog cov khoom khov mos. Piv txwv li, hauv lub chaw kho dej khib nyiab, cov txheej txheem kho dej ntws thiab thawj zaug feem ntau cuam tshuam nrog kev ntws ntawm cov dej khib nyiab nrog ntau yam khib nyiab. Cov kav dej roj hmab ntuj tuaj yeem tiv taus kev sib txhuam los ntawm cov khoom me me no thaum sib xws nroglub tshuab ntsuas hluav taws xob electromagnetic.Cov roj hmab ntuj tsim ua rau sab hauv du, txo qhov tsis kam ntawm kev ntws thiab ua kom muaj kev ntsuas qhov ntws raug los ntawm lub tshuab ntsuas hluav taws xob.

1.2 Cov Roj Hmab Ua Los Ntawm Khoom Siv (piv txwv li, Neoprene)

Cov roj hmab ua los ntawm cov khoom siv zoo li neoprene muaj kev tiv thaiv tshuaj lom neeg zoo dua li cov roj hmab ntuj. Cov kav dej uas muaj neoprene yog qhov tsim nyog rau kev ntsuas cov kua uas muaj xeb me ntsis, xws li qee cov kua qaub tsis muaj zog lossis alkalis hauv qhov ntau ntawm qhov tshwj xeeb. Hauv cov txheej txheem kev lag luam uas muaj cov tshuaj ntxuav tshuaj raug thauj mus rau hauv cov kav dej, cov kav dej uas muaj neoprene tuaj yeem siv ua ke nrogcov ntsuas hluav taws xob electromagnetic.Lub neoprene hauv ob sab tsis yog tsuas yog tiv thaiv cov kav dej los ntawm kev tawm tsam tshuaj lom neeg xwb tab sis kuj tseem tswj tau qhov kev ncaj ncees ntawm lub zog hluav taws xob siv rau kev ntsuas kev ntws, ua rau muaj kev txiav txim siab raug ntawm qhov nrawm ntawm cov kua dej uas muaj tshuaj lom neeg no.

2. Cov ntaub fluoropolymer

2.1 PTFE (Polytetrafluoroethylene)

PTFE muaj npe nrov rau nws txoj kev tiv thaiv tshuaj lom neeg zoo heev, muaj peev xwm tiv taus ntau yam tshuaj lom neeg corrosive heev, suav nrog cov kua qaub muaj zog, cov hauv paus, thiab cov neeg sawv cev oxidizing. Cov kav dej PTFE-lined feem ntau siv rau hauv kev lag luam tshuaj lom neeg, kev tsim tshuaj, thiab kev tsim khoom semiconductor. Hauv cov nroj tsuag tshuaj uas cov tshuaj lom neeg hnyav xws li cov kua qaub sulfuric acid lossis hydrofluoric acid raug xa mus, lub ntsuas hluav taws xob electromagnetic tuaj yeem ntsia tau rau ntawm cov kav dej PTFE-lined. Lub PTFE lining ua kom ntseeg tau tias cov kav dej tsis raug puas tsuaj los ntawm cov khoom siv corrosive, thiab nws cov khoom tsis conductive thiab ruaj khov tsis cuam tshuam rau lub hauv paus ntsiab lus ntsuas hluav taws xob. Qhov no tso cai rau kev ntsuas ntws meej txawm tias nyob rau hauv cov chaw muaj tshuaj lom neeg hnyav heev.

2.2 FEP (Fluorinated Ethylene Propylene)

FEP yog lwm yam khoom siv fluoropolymer hauv. Nws muaj kev tiv thaiv tshuaj zoo ib yam li PTFE tab sis muaj qee qhov zoo ntawm kev ua haujlwm tau zoo thiab pob tshab. Cov kav dej FEP feem ntau siv rau hauv cov ntawv thov uas xav tau kev tshuaj xyuas pom ntawm cov kua dej ntws ntxiv rau kev ntsuas qhov ntws kom raug. Piv txwv li, hauv qee qhov kev tshuaj ntsuam tshuaj lom neeg hauv chav kuaj lossis hauv kev tsim cov kua dej ntshiab hauv kev lag luam tshuaj, cov kav dej FEP tuaj yeem ua ke nrogcov ntsuas hluav taws xobQhov pob tshab ntawm FEP ua rau cov neeg teb xov tooj tuaj yeem saib xyuas qhov xwm txheej ntawm cov kua dej, thaum lub tshuab ntsuas hluav taws xob muab cov ntaub ntawv ntws tseeb.

3. Cov Khoom Siv Ua Los Ntawm Cov Khoom Uas ...

Cov kav dej uas muaj cov khoom siv ceramic yog qhov tsim nyog heev rau cov ntawv thov uas xav tau kev tiv taus kub thiab kev hnav zoo heev. Cov khoom siv ceramic muaj qhov kub yaj siab thiab tuaj yeem tswj tau lawv cov khoom siv kho tshuab thiab tshuaj lom neeg ntawm qhov kub siab. Hauv kev lag luam xws li kev tsim hluav taws xob, qhov twg muaj cov pa roj kub uas muaj tshauv kub lossis cov dej kub siab, cov kav dej ceramic tuaj yeem siv nrog cov ntsuas hluav taws xob electromagnetic. Cov ntaub ceramic tiv thaiv cov kav dej los ntawm kev cuam tshuam ntawm cov khoom me me hauv cov kua dej, thiab lub ntsuas hluav taws xob electromagnetic tuaj yeem ntsuas qhov nrawm ntawm cov kua dej kub siab no. Txawm hais tias cov khoom siv ceramic yog cov khoom siv tawg yooj yim, kev teeb tsa thiab tsim cov kav dej kom raug tuaj yeem ua kom lawv ua haujlwm tau ntev nrog cov ntsuas hluav taws xob electromagnetic.

Xaus lus,cov ntsuas hluav taws xobsiv tau zoo nrog cov kav dej uas muaj roj hmab (ob qho tib si ntuj thiab hluavtaws), fluoropolymers (PTFE thiab FEP), thiab ceramics. Kev xaiv cov khoom siv hauv pem teb nyob ntawm cov yam ntxwv tshwj xeeb ntawm cov khoom ntsuas, xws li nws cov tshuaj lom neeg, kub, thiab kev sib txhuam, kom ntseeg tau tias qhov ntsuas dej ntws raug thiab txhim khu kev qha.
