Fineco Mounting thiab Cov Khoom Siv Vuam 
Dab tsi yog ib tug txiv neej xav pom ntawm qhov pom ntawm dej tank, hauv qab thiab phab ntsa yog them nrog cov hnoos qeev, xeb ntawm cov keeb kwm tsis paub. Ntxiv mus, saib cov dej ntws ntawm cov tshuaj no mus rau lub tshuab tsom thiab tshawb pom lub neej nyob rau hauv nws tsis muaj qhov txaus ntshai rau tus txiv neej muaj tub rog muaj sia thiab. Xav txog, koj muab cov kua no haus, ua ntej tua cov tshuaj tua kab mob: ntxiv chlorine rau dej
Tag nrho cov saum toj no tag nrho yog hais txog cov khaub ncaws tsoos lossis tooj liab dej, los ntawm qhov twg nws tsis yog haus dej, feem ntau txawm tias tsis muaj npau npau. Qhov ntawd yog qhov tshwm sim, cov kws kho mob thiab cov neeg ua haujlwm ntawm txoj kev pabcuam ntawm kev sib tw tau paub zoo.
Yog li, qhov xwm txheej ntawm kev cia siab? Calm down, txhua yam tsis zoo li nws yuav yog. Thaum ntxov, kaum xyoo mus rau Lavxias lag luam lag luam rau cov kav dej thiab cov kais dej ntws tau txhaj los ntawm cov khoom lag luam thiab cov khoom siv. Cov neeg ua haujlwm tau muab cov thev naus laus zis tshiab rau kev tso cov kav dej los ntawm polyethylene tshiab, fiberglass, polypinylene, polyvinyl chloride, los ntawm cov hlau-polymer. Viyul 1996. Lub nroog coungium ntawm kev tsim kho ntawm Lavxias Federation txiav txim siab mus rau kev siv cov khoom siv ntawm cov kav dej, sib txuas thiab xauv kev txhawb nqa los ntawm polymeric Cov ntaub ntawv. Txog rau tam sim no, ntau cov kev cai tau ua haujlwm nyob rau hauv Russia, tau hais txog kev siv polymer piper hauv cov tshuab khoom noj. (Tsev kawm ntawv ntawm SP-40-101 cov kev cai, SNIP 2.04-85, SNIPTION 3.05.0-5, CH 478-80, CH 550-82, thiab lwm yam).
Cov nplai ntawm cov kav dej, txuas thiab cov duab sib txuas los ntawm cov ntaub ntawv polymeric yog qhov tsis tshua muaj neeg coob heev. Peb yuav tsom rau qhov teeb meem ntawm cov dej txias thiab dej kub, qhov kev daws teeb meem zoo tshaj plaws, yog kev siv cov neeg tshwj xeeb, yog kev siv dej sib txuas, polyvinyl chloride, polybutene thiab lwm cov ntaub ntawv polymeric. Twb tau ntau xyoo thoob plaws lub ntiaj teb, polypropylene txaus siab rau kev ntseeg siab.
Nyob rau hauv Russia, kaum tawm ntawm cov tuam txhab txawv teb chaws thiab hauv tsev yog muab nyob rau hauv Russia hauv tebchaws Russia hauv kev tsim khoom lag luam thiab nruab ntawm kev tsim khoom lag luam los ntawm cov polymers. Nws nquag nrhiav tau ntxiv dag zog rau lub nkoj German AquathriMmbh, nws cov kav dej sib txuas tau pom cov khoom lag luam hauv Tebchaws Europe thiab cov khoom siv hiav txwv. Cov ntaub ntawv thoob ntiaj teb, sib dhos ua ke thiab kev teeb tsa vuam cov khoom siv Turkish Teknayn, uas nws cov polypropylene kav thiab tau tsim nyog los ntawm tus neeg sawv cev ntawm cov kav dej polypropylene yog npaj tau Txhawm rau muab ob lub tuam txhab Moscow: "Tokk- kav dej" thiab "Mont".
Txawm li cas los xij, cov thawj coj hauv kev teeb tsa ntawm cov kav dej ntawm cov kav dej ntawm cov tub kab ke hauv tebchaws Nroog "Randrropylene" (Pazuniversal +, uas tsis yog tsuas yog koom nrog hauv lub teeb tsa dej Khoom siv cov tshuab thiab muag cov ntaub ntawv los ntawm polypropylene, thiab siv kev qhia loj - teeb meem txhawb nqa thev naus laus zis ntawm "kev tsim kho tshiab" ntawm lub xyoo pua tom ntej.
Polypropylene yog ib lub npe dav dav ntawm tag nrho cov pab pawg ntawm cov polymers, qee qhov uas siv hauv kev tsim kho. Cov txheej txheem ntawm cov kav dej thiab cov sib txuas tau siv los ntawm cov hom hauv qab no polypropylene:
- Hom 1 (PP-1) Siv feem rau cov khoom siv txias dej, raws li lim dej thiab thev naus laus zis thev naus laus zis.
- Hom 3 (PP-3) lossis "copolymer random", PPRC ua qauv ua lag luam. Cov raj dej ntawm nws yog siv ob qho tib si rau cov dej txias thiab dej kub nrog qhov dej kub tsis tu ncua tsis siab dua 70s.
- Hostalen 5216/34 Polypropylene, tsim los ntawm Hoechst, txhais tau tias yog Ppph , cov kav dej los ntawm uas yog nrog lub sijhawm ntev rau 95c thiab tuaj yeem siv hauv cov cua sov tshuab.
Hauv tebchaws Russia, polypropylene PP-3 (PPRC) tau txais kev faib tawm loj tshaj plaws. Nws yog tus cwj pwm los ntawm cov teeb meem siab ntawm cov khoom, tshwj xeeb tshaj yog ua rau deformation thiab tawg ntawm kev tsim kho qhov kub. Cov khoom siv no tsis hloov pauv lub cev thiab tshuaj lom neeg ntawm cov dej. Sab hauv ntawm PPRC tshem tawm cov kev txhim kho cov kab mob thiab cov kab mob pob fungal microorganism. Pipyrropylene Pipelines ua kom txaus siab tshaj plaws cov kev xav tau niaj hnub no.
Cov tub rog polypropylene, hauv kev sib piv rau cov txiv qaub, tsis txhob ua rau xeb thiab corrosion thiab corrosion thiab corrosion thiab corrorres, hauv ntau qhov ntau nyob hauv cov dej haus. Thaum khov khov, lub pprc polypropylene raj xa dej tsis yog pov tseg. Cov ntaub ntawv tsis-electro-conductive, thiab nws txhais tau tias tsis raug rau kev ua kom muaj kev puas tsuaj ntawm wandering dej ntws thiab ferructured.
Pov tseg thaum txhim kho lossis vuam polypropylene kav yog cov tsis muaj hlo li. Qhov ceev ntawm cov haujlwm no hauv kev sib piv nrog cov kav hlau hlau yog 2-4 zaug siab dua. Tab sis lub ntsiab zoo ntawm cov kav dej zoo li tsawg: lawv muaj txog li 30% pheej yig dua li cov hlau galvanized ntawm tib lub taub. Ieto tsis tau coj mus rau hauv tus lej nyiaj ua haujlwm!
Lub neej lav lub neej ntawm PPRC cov kav dej hauv cov dej txias yog tsawg kawg yog 50 xyoo, hauv qhov kub ntawm tsis tshaj 70s) - tsawg kawg 25 xyoos.
Peb txhua tus paub txog dab tsi yog lub installation lossis hloov ntawm tus kais system los ntawm cov kav dej hlau. Qhov no yog cov neeg ua haujlwm nrog cov thooj voos kheej thiab tsis muaj zog, tsis muaj dab tsi, tsis muaj dab tsi thiab cov khoom siv sib tshooj ntxiv los ntawm kev sib txuas ntawm kev sib txuas tsis xws luag. Piv txwv li, lub installation ntawm lub yeeb nkab dej tshiab los ntawm steel galvanized cov yeeb nkab hauv lub tuam txhab me me hauv tsev los ntawm plaub tus neeg ua haujlwm tau siv ib lub lim tiam. Lwm lub lim tiam tau mus kho cov phab ntsa tawg thiab sib tshooj.
Thiab tam sim no xav txog xws li daim duab. Ib hnub busbar rau lub lawj ntawm lub tsev nyob rau hauv kev tsim kho yog tsav nce "Zhiguli" nrog ib pawg kav dej ntawm cov kav dej ntev. Cov hnab yas ntim nrog cov chaw sib txuas, lub zog txhawb nqa lub zog no, cov nrawm dua thiab cov ntaub ntawv nrog cov cuab yeej tau muab rho tawm ntawm pob tw. Ob tug hais mav-Installers hauv lub teeb cov khaub ncaws cov khaub ncaws spores tau qhia meej meej rau hauv chav. Tshwj xeeb yeeb nkab txiab yog txiav rau hauv daim ntawm qhov kev xav tau ntev. Tom qab ib nrab ib teev, raws li txoj haujlwm, lawv pib pib ntawm cov chaw yav tom ntej sib xyaw ua ntej ua ntej qhov ua ntej qhov ua haujlwm hauv phab ntsa.
Ib teev tom qab, txhua yam yog npaj tau sib cuag thermal vuam (vuam los ntawm fusion) kav. Lub lim tiam Tees los ntawm cov yeeb nkab tseem ceeb ntawm cov plag tsev yuav tsum tau rho tawm chaw da dej, chav dej, mus rau chav ua noj, hauv chav nres tsheb. Tom qab ib nrab-teev so, cov neeg ua haujlwm tshem tawm cov tshuab hluav taws xob tshwj xeeb los ntawm cov npoo ntawm cov polypropylene seem rau qhov kub ntawm 260C. Ob lub taub hau hloov tau cov tes nrog cov tes tsho thiab cov khoom lag luam ntawm qhov loj me ntawm cov welded yog nyiam rau cov khoom cua kub.
Kev sib txuas rau cov chaw yog degreasing nrog tampon, moistened nrog cawv. Tom ntej no, cov yeeb nkab tau tso rau hauv lub tes tsho, thiab Tee yog txuas rau lub taub hau ntawm lub taub hau vuam, uas lawv tau ua kom sov rau ob peb lub cheeb ntawm cov khoom ntawm cov khoom lag luam thiab ntau ntawm 5 Txog 40 seconds), tom qab uas cov yeeb nkab tau tso rau hauv tee rau qhov tob cim nrog ib mem hluav taws axis. Lub thermal tiv tauj ib nrab ib nrab ib feeb (rau ib lub twj nyias (rau lub sijhawm nyias nyias, yog tias, cov khoom yog welded ntawm molecular qib ua ib monolithic integer. Cov haujlwm zoo sib xws yog ua rau txuas lwm feem thiab thaum vuam txuas ntxiv cov yeeb nkab ntxiv.
Vuam siv sijhawm li ob teev. Siv cov fasteners yuav tsum muaj sijhawm ntau dua. Kev nkag mus ua haujlwm tau tshwm sim qhov yuav tsum tau txuas ib polypropylene riser rau cov yeeb nkab cov yeeb nkab ntawm cov dej. Txhawm rau ua qhov no, lub carving yog txiav ntawm cov yeeb nkab steel thiab cov yeeb nkab tau txiav siv tshwj xeeb sib xyaw ua ke (polypropylene hlau), lub pob kaw tau nruab rau tib txoj kev.
Txog thaum kawg ntawm hnub ua haujlwm, dej tau txais kev pab hauv riser. Tus tswv thiab foreman bypass lub tsev: tsis yog ib qho xau! Raws li daim ntawv cog lus, kev ua haujlwm tau txiav txim siab ua tau. Kev sib txuas lus ntawm lub xyoo, lub tuam txhab tau raug xa mus rau cov kev pab dawb ntawm cov txheej txheem tsim los ntawm nws cov kws tshaj lij.
Hauv cov kev ntsuam xyuas nrov npe tom qab polyplopene kav, polyvinyl chloride (PVC) thiab chlorinated polyvinyl chloride (CPVC) yog ua raws. Cov tho kev hauv kev tsim cov dej ntim khoom thiab cov cua sov los ntawm cov ntaub ntawv no yog American kev txhawj xeeb Nibco, uas nws cov khoom lag luam kuj pom siv hauv kev tsim vaj tsev nyob hauv Russia. Cov tshuab hu ua Flowguard thiab FlowgurdGold yog kev sim ua tiav hauv Asmeskas rau 30 xyoo. Raws li nws PVC thiab CPVC cov ntsuas, feem ntau zoo ib yam li PPRC-3 thiab Hostalen 5216/34 polypropylene (pph). Onno pvc kav txawv txawv ntawm lwm cov hluav taws kub: qhov kev kub siab ntawm cov kav dej polyvinths uas tau tso cai rau cov khoom siv hluav taws kub mount tua hluav taws. Polyvinyl chloride cua sov tshuab ua kev tso cai siv 35% ntawm cov toosol daws. Thaum kawg, lawv tiv taus cov kev cuam tshuam txhua yam dua li Polypropylene. Tus nqi ntawm polyvinyl chloride kav yog qis dua steel galvanized.
Fiberglass kav yog ua ib tus neeg sib tw loj ntawm cov kav hlau steel. Lawv withst ib tug loj (txog 100 atmospheres siab, kub-resistant thiab tiv taus dej kub. Lawv muaj peev xwm them tus kheej, hauv qee yam mob tuaj yeem muab ntim nrog hauv pob zeb. Tus nqi ntawm fiberglass kav yog cov xim hlau ntxiv rau xim hlau, tab sis lawv lub neej pabcuam yog 3-5 zaug ntxiv.
Tsis ntev los no, kav dej los ntawm stitched polyethylene (hla polyethylene) tsim los ntawm Swedish kev txhawj xeeb Wirsbo thiab lub tuam txhab German rehat tau tshwm sim ntawm Lavxias kev ua lag luam. Nws yog tus cwj pwm los ntawm kev yoog raws (cov kav dej tuaj yeem khoov tau ntawm txhua lub kaum sab xis), Freem kuj zoo rau cov cua sov, uas feem ntau siv nyob rau hauv cov cua sov hauv ib cheeb tsam. Qhov kub ntawm kev ua haujlwm ntawm Swedish kaw lus- txog hom kev ua haujlwm rau 110 ° C), ua haujlwm siab yog txog li 10thmmospherespress thiab hom luv). Txhim kho yog nqa los ntawm cov cuab yeej tes tsis muaj gluing, vuam thiab soldering, uas yooj yim heev hauv lub teb. Stitched polyethylene muaj molecular nco: kev ntsuas ntawm cov yeeb nkab "kev coj ua ntawm lub tuam txhab, yog siab dua lub zog ntawm cov yeeb nkab nws tus kheej. Tus nqi ntawm cov kav dej los ntawm polyethylene yog siab dua li hlau galvanized, tab sis kev pabcuam lub neej hauv 3rd ntau dua.
Ripin Mounting Refau-contring Siv ergonomic box rau ua ke installation teeb meem ntawm cov khoom siv hluav taws xob thiab hluav taws xob. Hauv qhov no, lub thawv hluav taws xob ntawm lub thawv tseem ib txwm hermetic, qhov kub nyob rau hauv nws tsis pub tshaj 30s.
Hauv dej txias thiab cua sov thiab cov cua sov tshuab, kav dej ua los ntawm polybutene thiab livinylene fluoride ua tau los ntawm Swiss tuam txhab kuj tseem siv tau. Lawv tau txawv los ntawm high (up to135C) ntsuas kub thiab tshuaj lom neeg, uas tau xav txog kev siv cov kav dej sov, nrog rau cov ntsuas cua sov nrog cov kub ntxiv. Xws li cov kav dej, txawm li cas los xij, muaj ntau dua kim dua li cov saum toj no. Cov txheej txheem ntawm lawv compound yuav tsum muaj kev cob qhia tshwj xeeb.
Nrog rov tshwm sim ntawm cov khoom siv tshiab, cov kab lis kev cai ntawm cov kav dej, uas tseem yog ib txwm muaj feem cuam tshuam hauv kev nco qab ntawm cov pej xeem nrog tus kws tshaj lij dej cawv. Niaj hnub no, lawv tau hloov los ntawm cov neeg ntse, sai thiab ua tib zoo ua lawv txoj haujlwm nruj me ntsis ntawm cov nqi ntawm cov nqi ntawm lub tuam txhab.
Cov kws kho mob ua tsaug rau tus thawj coj ntawm NGO kev cob qhia "V.SONS ntawm DAMENSION LLP nyob rau hauv cov txheej txheem ntawm kev ua haujlwm ntawm lub tsev lag luam thiab hauv kev npaj ntawm tsab xov xwm.
