Collector rau txuas lub khawm ntawm lub tsev sov los ntawm Aquarm
Kawg fittings rau txuas ntau ntau hom pipes rau tus collector
Nias Fittings ntawm Ntau Cov Chaw Tsim Tshuaj
Hlau yas pipes nrog txoj kab uas hla mus txog 32mm yog muab rau bays. Nyob ntawm txoj kab feem thiab chaw tsim khoom ntev ntawm cov yeeb nkab hauv lub Bay tuaj yeem sib txawv ntawm 50 mus rau 500m
Niaj hnub no, lub teeb tsa ntawm cov dej sov sov yog tsis yooj yim sua kom tsis xav muaj polymer thiab hlau-polymer kav dej uas txawv hauv cov khoom, tsim qauv thiab cov yam ntxwv. Los ntawm teb rau ntau cov lus nug los ntawm cov nyeem ntawm phau ceev xwm txheej Internet forum, peb txiav txim siab los qhia ntxiv txog cov raj raj hluav taws xob tseem ceeb li cov kav dej thiab txuas cov ntsiab.
Nias Fitting ntaus ntawv:
1 tooj dag ntaus;
2-pob tshab yas nplhaib;
3- Sealing nplhaib los ntawm epdm;
4- Crimping Tes Tsho Stainless Hlau AISI 304;
5- Cov Yeeb Nkab Siv Hluav Taws Xob Hlau yas. Hlau-cov kav dej yas yog pom hauv online los ntawm ntau cov tuam ntxhab. Ntawm lawv- oventrop, tc, teceflex khoom (lub teb chaws Yelemees), Valsland), Volirama los ntawm Prandelli Super K Brandelli (Ltalis), Meterlas (Israel), LG (Kauslim Kauslim), Onor System nrog cov txheej hauv qab-RT, "Altais" (Russia) thiab ntau tus neeg.
Hlau-Yas Kav Muaj Txheej Txheem Txheej Txheem Sab Hauv Cov. Pex yog tau los ntawm "crosslinking" ntawm monomers hauv kev ua qauv peb-seem ntawm cov tshuaj (rhe thiab cov qauv ntawm lub cev (REXC) los ntawm. Rau PE-RT, cov txheej txheem tshuaj lom neeg ntawm Copolymerization yog siv. Hauv txhua kis, cov polymer kis tau muaj zog thiab yog li ntawd tuaj yeem ua haujlwm ntev (txog 50 xyoo) muaj ntau tus neeg hais lus yog qhov muaj lwm tus hauv tsev neeg ntawm Rex. Cov txheej txhuas yog siv los txo cov coefficient ntawm kub nthuav dav ntawm cov yeeb nkab. Nws tseem ua haujlwm ua cov pa oxygen-resistant thiab tso cai rau koj khaws cov duab ntawm cov yeeb nkab leaned los ntawm nws thaum pw.
Aluminium plhaub tej zaum muaj tuab ntawm 0.2 txog 2 hli. Aluminium kab xev nyob ib ncig ntawm txheej sab hauv tuaj yeem muab weaser vuam, zoo li cov yeeb nkab "altabe los ntawm ncu yog tsis welded txhua, zoo li lg. Txoj kev siab tshaj plaws yog liner vuam ntawm txhuas Ribbon Jack. Nws tso cai rau koj kom tau txais cov radii uas txaus (los ntawm 4-5 sab diam diameters) kav dej, nrog rau qhov ruaj khov ntawm cov duab txuas nrog. Hlau-cov kav yas yog tsim los ua haujlwm ntawm lub siab txog 10 bar thiab qhov kub thiab txias txog 95 C.
Tus nqi ntawm ib rab yeeb nkab ntawm cov yeeb nkab nrog txoj kab uas hla ntawm 16 hli yog 0.5-2.2 hauv cov tuam ntxhab sib txawv. Cov khoom zoo li no feem ntau siv nrog lub taub sab nraud ntawm ntawm 14 mus rau 32 mm thiab phab ntsa tuab ntawm 2-3mm, tab sis muaj cov diameters loj rau 110 hli.
Cov fittings rau ntau lub tshuab yog siv los txuas hlau-yas kav. Feem ntau cov yog Crimp (compression) fittings. Ntxiv rau, kho nrog cov yeeb nkab yog nqa tawm nrog lub nplhaib nias nrog lub txiv ntoo rau lub cev ntawm cov khoom, thiab kev sib khi yog ib qho zoo li EPDM foob. Lub nplhaib tuaj yeem muab faib ua ke, xws li cov khoom lag luam los ntawm kev ntsuas ntsuas dav dav (ltalis), thiab khoom, ltalis). Cov fittings cov pa hluav taws xob tau teeb tsa los ntawm cov cuab yeej sib xyaw, tab sis muaj kev sib tsoo, uas tsis tso cai rau kev xa lawv hauv cov qauv. Ib pab pawg zoo tuaj yeem suav nrog cov fittings xovxwm muaj xws ntawm lub cev ntawm cov khoom thiab lub tes tsho thiab lub cev sib txawv siv cov cuab yeej tshwj xeeb. Lub fittings ntawm mapla yeeb nkab los ntawm geberit tsis muaj lub tsho cracepita txhua, nws lub luag haujlwm yog ua los ntawm cov yeeb nkab muaj ib txheej txhuas nrog cov tuab ntawm 0.8 hli. Nias Fittings tsis muaj txiaj ntsig, raws li qhov uas lawv ntseeg tau yog siab tshaj qhov ntawm cov khoom ntawm thawj pawg. Txhawm rau nruab lawv, nias clamps uas tuaj yeem xauj rau hauv ntau cov tuam txhab tshwj xeeb.
Ib qho kev nthuav dav ntawm cov roj docking nrog cov fittings nrog kev pab ntawm lub tsho ntawm mobile tau pom zoo los ntawm German lub tuam txhab TC. Fittings muaj tib cov ntawv hla-seem, nrog rau cov yeeb nkab, yog li ntawd, tsis muaj cov kab hauv zos ntawm cov raj xa dej hauv zos, uas tsis tseem ceeb. Thaum txhim kho ua ntej, lub tes tsho rooj txav yog muab tso rau ntawm cov yeeb nkab ntawm cov cuab yeej-e-xeem thiab muab tso rau qhov sib txuas ntawm cov khoom sib txuas, tom qab ntawd lub tes tsho los ua ke siv tshwj xeeb twj.
Stitched polyethylene. Nrov heev nrog lub ntaus ntawv ntawm cov yeeb nkab sov ntawm cov yeeb nkab los ntawm thiaj li hu ua pa-resistant txheej evoh (raws li cov ethylinylhydrhydrhydrefoxide). Lawv raug tso tawm los ntawm Wirsbo (Sweden), Refenen), Refau (Yelemes (Whaland), Wavin), KAN-Pekk (Russia) thiab lwm cov tuam txhab.
Qhov txawv txav tshwj xeeb ntawm polyethylene kav yog qhov ua tau ntawm ntau lub voj voog kom khov-defrost. Qhov tsawg kawg yog khoov hluav taws xob ntawm cov kav dej no feem ntau yog 7-10 sab nraud diameters ntawm cov yeeb nkab. Feem ntau ntawm cov ntoo khaub lig txuas nrog Polyethylene kav dej muaj kev ua haujlwm ntawm lub siab txog li 6 atm, thaum lub sijhawm ua haujlwm yuav nce txog 95 C.
Rau cov kav dej los ntawm stitched polyethylene, fittings yog siv zoo sib xws uas siv rau hlau-yas kav. Qhov kev teeb tsa tshwj xeeb ntawm kev teeb tsa ceev, raws li cov molecular nco ntawm tus ntoo khaub lig-txuas, muab Wirsbo. Cov yeeb nkab nrog ntxiv rau nws nrog lub nplhaib ntawm tib cov ntaub ntawv nthuav dav lub expander, tom qab uas nws tau muab tso rau qhov haum. Tom qab qee lub sijhawm (2-3 feeb), vim yog cov roj molecular nco ntawm cov khoom, qhov loj ntawm cov yeeb nkab tau rov qab mus rau tus thawj, thiab yog li ua tiav nruj ntawm cov compound yog tiav. Tus nqi ntawm cov khoom no yog $ 1.2-1.8 rau 1 p. m ntawm tib lub taub. Lub diam ntawm 16-32mm nrog ib phab ntsa tuab ntawm 2-3mm yog npaj los ntawm lub tsho khuam. Cov tsheb ciav hlau thiab cov khaub ncaws ntxig yog tsim tawm.
Polybutene. Polybuten kav nrog ib txheej oxygen zoo sib xws-resistant txheej zoo siv. Cov neeg tsim khoom loj tshaj plaws ntawm cov khoom lag luam yog GabototM systemtechnic, Aquahais (Lub teb chaws Yelemees). Muaj tsawg dua li ntawm lwm hom pipes, lub Elastic Modulus, lawv muaj qhov sib txuas zoo dua thiab yog li muab cov radii ntau heev (qhov tsawg tshaj plaws ntawm lub taub dej). Qhov no tso cai rau koj kom nteg cov ntsiab lus nrog ib kauj ruam me me (txog li 50 hli) thiab yog li tau txais ntau dua thermal zog los ntawm sab nraud. Ntawm qhov kub ntawm 70 los ntawm kev pabcuam lub neej ntawm cov khoom no yog tsawg kawg tsib caug xyoo. Qhov txiaj ntsig tseem ceeb ntawm cov kav dej tau siv polybutene yog qhov ua tau zoo li kev siv tau. Lawv tau txuas nrog kev sib cuag thermal vuam rau hauv lub qhov (socket) (yuav luag qhov no zoo ib yam li cov kav dej polypropylene). Rau kev tiv thaiv, crimp fittings feem ntau yog thov rau cov neeg sau. Tus nqi ntawm Polybutene kav dej yog qhov sib piv rau tus nqi ntawm cov kav dej ntawm tib txoj kab uas hla ua los ntawm cov polyethylene. Lawv tsim nrog txoj kab uas hla 16, 17 thiab 20 hli, phab ntsa tuab yog 2 hli.
Txoj haujlwm sib tshuam nyob hlau-polymer kav nrog cov txheej hauv polybutene. Lawv raug tso tawm los ntawm Nioxy (Austria) thiab Universa (Slovakia). Txhua yam khoom yog plaub-txheej. Thawj (sab hauv) txheej yog polybuthene ntawm qhov siab hloov ntawm cov qauv hluav taws xob zoo, qhov thib peb tawg, yog ua los ntawm polyester fibers, Thiab nyob rau sab saum toj ntawm txhua yam npog cov hnab riam tiv thaiv kab mob tiv thaiv.
Sib haum. Cais, nws yuav tsum tau hais txog qhov sib xyaw ntawm cov kav dej thiab cov fittings. Feem ntau, cov tuam ntxhab lav cov teeb meem-dawb ua haujlwm ntawm lawv lub tshuab tsuas yog thaum siv cov khoom qub, nws tsis muaj tseeb rau txhua cov tuam ntxhab. Txawm li cas los xij, xws li cov khoom lag luam tau sib xws, nws tsuas yog tsim nyog xaiv cov haum kom raug, thaum tig tuaj saib tsis yog rau txoj kab uas haum, tab sis kuj nyob ntawm lub thickness ntawm nws phab ntsa. Tsuas yog cov khoom lag luam nrog cov hau kev qub ntawm cov compound tsis yog sib xyaw. Nws kuj yuav tsum tau nyob hauv siab tias xws li fittings tau thov tsuas yog siv rau hom kav dej uas lawv tau npaj. Piv txwv li, fittings rau hlau-yas kav tsis siv rau cov kav dej los ntawm stitched polyethylene thiab vice versa.
