Phaj heat exchanger yog cov cuab yeej siv hluav taws xob zoo heev, nws daim ntawv thov dav heev.
Phaj heat exchanger unit phaj kub exchanger rau cov khoom tseem ceeb yog phaj kub exchanger phaj thiab sealing gasket.
Thiab kev txhim kho qib ntawm sealing gasket ncaj qha txiav txim siab txog qib kev loj hlob ntawm cov phaj kub exchanger.
Phaj kub exchanger foob tsis ua hauj lwm yog ib qho tseem ceeb heev lawm tsis ua hauj lwm, yog li dab tsi yog vim li cas rau phaj kub exchanger foob tsis ua hauj lwm?
Peb yam tseem ceeb cuam tshuam rau lub foob
1, zog
Tshem tau phaj kub exchanger nyob rau hauv lub ntsuas ua hauj lwm siab nyob rau hauv kev siv ntawm to.
Ntxiv nrog rau cov cuab yeej hauv kev tsim khoom ntawm cov khoom sib dhos zoo.
Feem ntau thiab lub kaw lus nyob rau hauv qhov txawv txav load cuam tshuam.
Qhov no yog ib qho mob uas tsis tau pom meej meej rau tus neeg ua haujlwm li cas.
Lub siab ceev ceev ceev uas tshwm sim los ntawm kev poob siab yog feem ntau txog ob zaug siab dua qhov kev khiav hauj lwm siab.
Cov roj hmab gasket ntsia rau hauv lub phaj kub exchanger yog hloov chaw, ua rau lub phaj kub exchanger foob tsis ua hauj lwm.
Lub sealing ntawm lub phaj kub exchanger ua tsis tau.
Vim tias cov khoom siv hluav taws xob hloov hluav taws xob ntawm hom khoom siv no siv cov ntawv hlau stainless hlau ntau lawm.
Nws sealing rigidity kuj tsis zoo.
Nyob rau tib lub sij hawm, lub perimeter ntawm lub foob yog ntev heev.
Yog li ntawd, qhov kev ua tau zoo ntawm kev cuam tshuam tsis zoo tshaj lub plhaub thiab lub raj cua kub exchanger qis.
2, cas
Siv los yog siv cov khoom siv tsis siv neeg ntau xyoo.
Seal khoom aging tej zaum yuav cuam tshuam qhov kev cia siab ntawm lub foob.
Yog li yuav tsum tau ua kom zoo dua ntawm kev saib xyuas los hloov lub sealing gasket tshiab raws sijhawm.
3, Kub
Kev hloov ceev ntawm qhov kub thiab txias tuaj yeem ua rau lub foob tsis ua haujlwm.
Nyob rau hauv lub kub hloov sai, lub
Roj hmab gasket coefficient ntawm linear expansion thiab elastic deformation thiab sealing preload yuav tsis phim.
Yog li ntawd lub sealing preload txo.
Qhov tshwm sim yog tias cov cuab yeej qis dua li qhov ntsuas tsim siab.
Peb yam saum toj no yog cov laj thawj tseem ceeb rau kev foob tsis ua haujlwm, kev foob tsis ua haujlwm tshwm sim, yuav tsum tau tshawb xyuas sai li sai tau los daws qhov teeb meem, kom tsis txhob muaj kev poob qis.
Nyob rau hauv cov txheej txheem kev lag luam cov cuab yeej, phaj kub exchanger yog ib tug siab kev ruaj ntseg yuav tsum tau ntawm cov khoom, thaum lub gasket puas lawm, cov tsos ntawm sab nraud drip to pom.
Phaj kub exchangers yog paub tias yuav drip me ntsis thaum xub thawj, thiab nyob rau hauv cov txheej txheem cov khoom uas muaj kev kub siab cuam tshuam, loj xau yuav tshwm sim vim gasket puas.
Nyob rau hauv lub siab muaj zog shocks, lub gasket tej zaum yuav raug tsiv tawm ntawm qhov tseeb installation txoj hauj lwm ntawm lub phaj kub exchanger, thiab nyob rau hauv loj heev zaum, txawm dislodged los ntawm lub tshav kub exchanger.
Nyob rau hauv cov ntaub ntawv no, tam sim ntawd tso tseg kev ua hauj lwm ntawm cov cuab yeej, thiaj li hais tias lub tshav kub exchanger nyob rau hauv tsis muaj lub siab kom txias mus rau chav tsev kub.
Yog hais tias lub gasket tau deformed nyob rau hauv qhov kev txiav txim ntawm lub siab poob siab, nws tsis tuaj yeem rov qab los rau nws qhov qub thiab txoj hauj lwm thiab yuav tsum tau hloov nrog ib qho tshiab.
Yog tias tsis muaj cov khoom seem, tshem cov phaj ntawm ob sab ntawm lub gasket puas los ntawm tag nrho cov phaj kub exchanger teeb, thiab tom qab ntawd tshuaj xyuas lub gasket bonding nto ntawm cov phaj phaj kub exchanger seem. Sib sau cov phaj nrog cov gasket puas tau muab rho tawm rau ib ntus thaum muaj xwm txheej ceev.
Tom qab ntawd yuav cov roj hmab gasket tshiab thiab ntxiv cov phaj kom ua tiav qhov kev hloov hluav taws xob qub.
Thaum lub sij hawm disassembly thiab sib dhos ntawm lub phaj kub exchanger, them sai sai mus rau lub A-tus nqi, uas yog lub clamping loj.
