Phaj heat exchanger yog cov khoom siv hluav taws xob zoo heev, nws daim ntawv thov yog dav heev, cov khoom tseem ceeb ntawm cov phaj kub exchanger yog cov phaj hlau phaj thiab sealant gasket. Kev txhim kho qib ntawm lub sealing ncoo ncaj qha txiav txim siab qhov 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?
Cov ntsiab lus raws li hauv qab no: muaj cov teebmeem tseem ceeb, qhov kub thiab txias thiab lub sijhawm cuam tshuam.
1. Cov nyhuv siab
Tshem tau phaj kub exchanger nyob rau hauv cov ntsuas kev ua hauj lwm siab nyob rau hauv kev siv ntawm to, ntxiv rau cov cuab yeej nyob rau hauv lub tsim ntawm lub rooj sib txoos zoo yam tseem ceeb, feem ntau thiab lub kaw lus nyob rau hauv lub txawv txawv load cuam tshuam rau qhov no tsis yooj yim rau cov neeg ua hauj lwm zoo tib yam saib qhov teeb meem. , qhov cuam tshuam los ntawm lub siab ceev ceev yog feem ntau siab dua qhov kev ua haujlwm siab li ntawm 2 zaug, yog li ntawd lub installation ntawm phaj kub exchanger nyob rau hauv cov roj hmab sealing gasket displacement Lub sealing tsis ua hauj lwm ntawm lub phaj kub exchanger, vim hais tias lub tshav kub hloov lwm lub tsev. ntawm cov khoom siv no siv cov ntawv hlau tsis muaj steel hlau ntau lawm, nws yog qhov tsis zoo sealing rigidity, thaum lub sealing ntawm lub periphery yog ntev heev, yog li qhov kev ua tau zoo ntawm kev cuam tshuam tsis zoo tshaj lub plhaub thiab lub raj kub exchanger yog tsawg.
2. Lub sij hawm cuam tshuam
Siv los yog tsis ua haujlwm rau ntau xyoo ntawm cov cuab yeej, cov ntaub ntawv sib khi ntawm lawv tus kheej kev laus tuaj yeem cuam tshuam qhov kev ntseeg siab ntawm lub foob, yog li koj yuav tsum tau siv sijhawm zoo los hloov lub sealing gasket tshiab raws sijhawm.
3. Kev kub ntxhov
Kev hloov pauv sai ntawm qhov kub thiab txias tuaj yeem ua rau lub foob tsis ua haujlwm, nyob rau hauv qhov kub hloov pauv sai heev, roj hmab gasket coefficient ntawm kev nthuav dav thiab elastic deformation thiab sealing preload yuav tsis sib xws, yog li ntawd lub sealing preload yog txo, ua rau cov cuab yeej bearing siab dua. qhov ntsuas tsim siab yog qis dua.
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 yam khoom uas muaj kev ruaj ntseg yuav tsum tau, thiab thaum lub gasket puas lawm, lub sab nraud drip to pom. Plate heat exchangers tag nrho muaj me ntsis dripping leaks pib nrog, thiab nyob rau hauv cov txheej txheem cov cuab yeej nrog kev kub siab shocks, loj los 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 phaj tom qab rho tawm cov gasket puas lawm. Lub phaj kub exchanger chav tsev yog ces yuav nrog ib tug tshiab roj hmab gasket thiab daim hlau yog ntxiv kom ua tau raws li tus thawj kub exchanger peev. Tus txheej txheem ntawm disassembling lub phaj kub exchanger yuav tsum tau them sai sai mus rau lub A-tus nqi, uas yog lub clamping loj.
