Vim li cas lub tshav kub exchanger flanges xau?

Plhaub thiab raj kub exchangersyog qhov tseem ceeb rau kev nyab xeeb thiab ua haujlwm tau zoo thiab yuav tsum tsis txhob xau. Txawm hais tias koj nyob hauv cov khoom noj thiab dej haus, tshuaj lom neeg, lossis kev lag luam tshuaj, txawm tias qhov xau me me tuaj yeem ua rau muaj teeb meem loj: poob ntawm cov khoom lag luam, kev sib kis ntawm cov khoom, kev puas tsuaj ib puag ncig, lossis hluav taws kub.

Ib qho chaw rau cov dej xau yog qhov flange.

Kev nkag siab txog qhov ua rau flange leaks thiab yuav kho lawv li cas tuaj yeem pab koj ua haujlwm zoo dua.

Lub tshav kub exchanger flange yog ib qho tseem ceeb ntawm cov kav dej thiab cov khoom siv. Nws yog siv los kho cov khoom siv thiab cov kav dej, ua kom muaj kev ruaj ntseg thiab tiv thaiv cov dej xau. Lub tshav kub exchanger flange feem ntau muaj flange phaj, bolts, thiab gasket.

Raws li cov qauv sib txawv thiab kev siv sijhawm, cov khoom siv hluav taws xob sib txawv tuaj yeem muab faib ua ntau hom, suav nrog cov hauv qab no:

 Ordinary flanges: Tsim nyog rau cov khoom siv hluav taws xob sib txawv nyob rau hauv qhov dav dav thiab qhov kub thiab txias;

 Siab - siab flanges: Haum rau cov khoom siv hluav taws xob sib txawv hauv qhov kub thiab txias;

 Anti-corrosion flanges: Haum rau lub sijhawm uas qhov nruab nrab kub hloov pauv yog corrosive;

 Tsawg-kub flanges: Tsim nyog rau cov khoom siv hluav taws xob sib hloov hauv qhov qis- qhov kub thiab txias.

Thermal Stress & Flange Distortion

Cov khoom siv hluav taws xob sib txawv tau tsim los tswj qhov kub ntawm qhov dav dav -tab sis qhov sib txawv ntawm qhov kub thiab txias tseem tuaj yeem ua rau cov hlau txuas ntxiv thiab cog lus sib txawv, ua rau flange warping lossis misalignment. Yog tias qhov sib txawv tshaj li ntawm 110℃(230℃F), yuav tsum tau ceev faj ntxiv thaum tsim lossis kho.

Yuav tiv thaiv kev cuam tshuam li cas -txog xau:

• Ua kom flange thiab tube ntawv thickness
• Siv cov txiaj ntsig kev ntxhov siab ntau dua hauv kev suav
• Txo qhov tso cai flange rigidity index
• Nce tus ntsia liaj qhov rooj piv rau 120% ntawm tus nqi tsim thiab khiav tag nrho cov ntsia liaj qhov rooj -load tsom xam

Loose los yog tsis tsim nyog torqued bolts

Thaum tshav kub kub, kev vibration, thiab lub siab tuaj yeem ua rau cov bolts xoob thaum lub sijhawm- ua rau poob ntawm gasket compression thiab qhov tshwm sim los. Retightening bolts yog qhov pib, tab sis ua nws tsis raug lossis ntau dhau tuaj yeem npog qhov teeb meem loj dua.

Cov kev coj ua zoo tshaj plaws:

• Siv cov txheej txheem torquing kom raug: kub torquing lossis hydraulic tensioning yog qhov zoo dua li kev ceev ceev.
• Tshawb xyuas cov xim ntau dhau ntawm cov bolts: cov coatings degraded tuaj yeem txo cov bolt load dhau sijhawm.
• Xyuas kom tus qauv tsim txhawb nqa kev faib khoom kom raug thiab tuav kev ntxhov siab.

Kho vajtse tsis txaus lossis Gasket Design

Kev xau tsis tu ncua-txawm tias tom qab qhov ntsia hlau torquing tsim nyog- tuaj yeem qhia tias muaj teeb meem loj dua nrog koj lub gasket lossis kho vajtse teeb tsa.

Ob txoj kev daws teeb meem zoo:

• Disc caij nplooj ntoos hlav ntxhua khaub ncaws: Cov no pab tswj cov ntsia liaj qhov rooj tas li txawm tias thermal expansion thiab contraction
• Weld nplhaib gaskets: Cov khoom siv txuas ntxiv no yog welded rau hauv qhov chaw, khaws cov khoom sib khi uas muaj thiab tiv thaiv deformation lossis scuffing los ntawm kev txav mus los.

Txawm hais tias koj lub tshuab hloov hluav taws xob yog hom tshiab - tshiab lossis tau ua haujlwm tau ntau xyoo, flange leaks yuav tsum tsis txhob raug ignored. Lawv feem ntau ceeb toom cov teeb meem loj dua - xws li kev siab dhau, kev sib dhos tsis raug, lossis xav tau kev tsim qauv zoo dua.
