Ib qho tshiab PTFE lub tshuab hluav taws xob hloov pauv pib xau ntawm lub tank nozzle tsuas yog hnub tom qab pib. Hauv lwm qhov xwm txheej, qhov sib pauv maj mam sags dhau lub hlis, ua rau muaj kev ntxhov siab rau PTFE pob thiab ua rau lub raj deformation. Cov no yog qhov ua tsis tau zoo thiab raug nqi ntau pom ntawm cov txheej txheem tshuaj chemical. Ob qho teeb meem feem ntau taug qab mus rau tib lub hauv paus ua rau: sab tsis raug -mounted installation. Rau cov engineers cog thiab cov pab pawg txhim kho, tau txais ib sab -mounted PTFE heat exchanger txoj cai thawj zaug yog qhov tseem ceeb rau lub sij hawm ntev - tiv thaiv cov pa tawm thiab cov neeg kho tshuab kev ntseeg tau.
Kev Npaj Nozzle: Lub hauv paus ntawm kev vam meej
Lub tank nozzle yog ib qho tseem ceeb tshaj plaws interface nyob rau hauv ib sab -mounted installation. Nws yuav tsum tau ua tib zoo sib xws, theem, thiab ntxiv dag zog. Ua ntej installation, xyuas kom meej tias lub nozzle yog perpendicular mus rau lub tank phab ntsa thiab muaj ib tug ca, du sealing nto tsis muaj weld spatter los yog distortion. Rau cov yas lossis fiberglass tso tsheb hlau luam, thaj tsam nozzle yuav tsum tau ntxiv nrog lub phaj rov qab los yog gusset kom tsis txhob nkag mus rau hauv qhov hnyav ntawm qhov sib pauv.
Ib qho kev soj ntsuam hauv cheeb tsam yog tias muaj ntau qhov xau tshwm sim vim hais tias lub nozzle tsis zoo sib xws thaum lub tank tsim. Txawm tias 2-3℃qaij tsim tsis sib xws gasket compression thiab nws thiaj li to. Ib txwm siv cov qib precision thiab dial taw qhia kom paub meej tias kev sib raug zoo ua ntej pib ua haujlwm.
Gasket Xaiv thiab Compression
PTFE kub exchangers yuav tsum tau tshaj gaskets kom ua tau ib tug txhim khu kev qha foob. Expanded PTFE (ePTFE) gaskets yog tus qauv xaiv vim lawv ua tau zoo rau qhov me me qhov tsis sib xws thiab tiv thaiv tshuaj tua kab mob thoob plaws pH ntau yam. Tsis txhob siv cov roj hmab txheem los yog compressed fiber ntau gaskets, vim lawv o los yog degrade thaum raug cov txheej txheem kua.
Kev tsim nyog gasket compression yog qhov tseem ceeb. Ua raws li cov chaw tsim khoom lub zog sib txuas- feem ntau yog criss- tus qauv hla hauv peb theem (30%, 60%, thiab 100% ntawm qhov kawg torque). Tshaj -nruj tuaj yeem tsoo lub PTFE flange, thaum nyob rau hauv - zawm ua rau xau. Cov kev paub dhau los qhia tau hais tias 90% ntawm cov dej ntws tawm los ntawm qhov tsis sib xws lossis tsis txaus gasket compression.
Kev them nyiaj yug ywj pheej tsis yog -Tshaj tawm
Ib qho kev ua yuam kev loj tshaj plaws thiab qhov teeb meem loj tshaj plaws yog cia lub tank nozzle dais tag nrho qhov hnyav ntawm lub tshav kub exchanger. Sab -mounted PTFE exchangers yog hnyav, tshwj xeeb tshaj yog nyob rau hauv ntau thiab tsawg. Lub nozzle tsuas yog tsim los muab cov xau- nruj kev sib txuas, tsis yog kev txhawb nqa.
Txhua sab -mounted unit yuav tsum muaj kev txhawb nqa ywj siab- los ntawm lub tank pem teb siv ob txhais ceg kho tau lossis los ntawm phab ntsa- mounted bracket. Qhov no tiv thaiv ntev -lub sij hawm kev ntxhov siab ntawm lub nozzle thiab PTFE pob. Hauv cov tso tsheb hlau luam yas, tsis muab kev txhawb nqa ywj pheej yuav luag ib txwm ua rau lub taub dej nkag thiab qhov tshwm sim tuaj yeem tsis pub dhau 12-18 lub hlis.
Insertion, Alignment, thiab Final Assembly
Ua ntej tso lub exchanger, siv ib txheej nyias ntawm cov roj nplua nyeem (xws li PTFE-raws li muab tshuaj txhuam) rau cov hlab thiab flange kom txo kev sib txhuam thiab tiv thaiv PTFE thaum lub sij hawm installation. Ua tib zoo coj cov pob khoom los ntawm lub nozzle, tsis txhob muaj kev sib cuag ntawm cov hlab thiab lub nozzle ntug uas tuaj yeem ua rau khawb lossis txiav.
Thaum lub ntsej muag flange sib raug zoo, tes-tighten lub bolts los tuav lub tsev nyob rau hauv qhov chaw, tom qab ntawd nruab qhov kev txhawb nqa ywj pheej thiab kho nws kom lub nozzle nqa xoom qhov hnyav. Tsuas yog tom qab ntawd ua qhov kawg bolt torquing nyob rau hauv criss -cross qauv. Tom qab kev teeb tsa, siab- sim qhov sib txuas nrog dej lossis roj inert ua ntej qhia cov txheej txheem tshuaj.
Xaus
Ib sab ua tiav-mounted PTFE heat exchanger installation nyob ntawm qhov kev npaj ntawm lub nozzle zoo, xaiv gasket kom raug thiab compression, thiab-qhov tseem ceeb tshaj plaws yog- muab kev txhawb nqa ywj siab. Lub tank nozzle yuav tsum tsis txhob nqa cov neeg kho tshuab load ntawm lub exchanger.
Rau cov chav loj lossis hnyav, thov kom paub meej cov duab kos los ntawm cov chaw tsim khoom uas qhia pom pom qhov chaw txhawb nqa thiab qhov tseem ceeb ntawm lub qhov rooj torque yog qhov tseem ceeb. Ua raws li cov kev coj ua no ua rau txo qis kev pheej hmoo ntawm kev xau thiab kev ua haujlwm tsis ua haujlwm, ua kom cov khoom sib pauv ua tau zoo rau ntau xyoo hauv cov cheeb tsam tshuaj lom neeg hnyav tshaj plaws.
