Kev kho dua tshiab ntawm chav tsev lossis tsev ntiav feem ntau tuaj yeem cuam tshuam nrog kev ua tiav lossis ib nrab hloov cov kav dej. Hauv cov tsev qub, lawv feem ntau yog hlau, tab sis tam sim no, raws li txoj cai, cov khoom siv polypropylene yog nyob rau hauv khw. Yog li, tus tswv tau ntsib cov lus nug ntawm yuav ua li cas txuas cov kav dej polypropylene nrog cov kav hlau?
Thaum twg nws yuav tsim nyog los txuas cov yeeb nkab polypropylene nrog ib lub hlau?
Qhov kev xav tau no tuaj yeem tshwm sim ob qho tib si thaum kho thiab kho tshiab ntawm cov kav dej uas twb muaj lawm, thiab thaum lub sijhawm tsim kho tshiab. Koj tsis tuaj yeem ua yam tsis tau txuas cov kav dej polypropylene nrog cov kav hlau hauv qab no:
- ua haujlwm ntawm ntau tus neeg cog lus ntawm ib lub chaw, lawv cov kev ua tsis tau zoo thiab siv cov kav dej los ntawm cov khoom sib txawv;
- muaj cov hlau leads ntawm cov khoom siv hauv tsev thiab kev lag luam;
- hloov ib feem ntawm kev sib txuas lus xwm txheej ceev;
- qhov xav tau los txuas cov raj xa mus rau cov txheej txheemCov khoom siv uas ua haujlwm ntawm qhov kub tseem ceeb rau cov kav dej polypropylene;
- tso txoj hauv kev tseem ceeb hauv cov kav dej, uas yav tom ntej yuav raug rau cov neeg kho tshuab thiab thermal stress.
Qhov laj thawj ntawm kev xav tau txuas cov kav dej los ntawm cov khoom sib txawv yog qhov sib txawv, yog li ntawd, txoj kev sib koom yuav tsum tau xaiv kom zoo rau cov xwm txheej uas twb muaj lawm.
Txoj kev siv cov kav hlau thiab polypropylene, lawv qhov sib txawv
Kev ua tau zoo ntawm cov raj xa dej ncaj qha nyob ntawm cov hlau siv los ua nws. Feem ntau nws yog:
- Cam khwb cia hlau, los ntawm kev sib txuas lus yog tsim nyob rau hauv cov tsev tsim nyob rau hauv Soviet lub sij hawm. Cov khoom yog tsis yooj yim, cov yeeb nkab tuaj yeem tawg nrog lub zog rauj tshuab.
- Hlau yog qhov cuam tshuam rau corrosion, thiab av thiab ntau yam impurities tuaj yeem sau rau hauv cov kav dej.
- Stainless steel, uas yog kim tshaj plaws tab sis nyuaj ua cov khoom siv nrog lub neej ua haujlwm ntev.
- Galvanized steel - nyuaj rau nruab, tab sis ua los ntawm kev ua tau zoo heev.
Txawm tias muaj qhov sib txawv muaj zog, kev sib txuas ntawm cov kav dej polypropylene nrog cov kav hlau tuaj yeem ua tau yooj yim. Tab sis thaum xaiv, nws yuav tsum nco ntsoov tias cov kav dej polypropylene tsis tiv taus qhov kub thiab txias (tus nqi ciam teb yog qhov kub ntawm +80.° C) thiab lawv qhov sib txawv. Yog li ntawd, feem ntau cov kav dej no tsuas yog ntsia hauv thaj chaw nyob xwb.
hom kev sib txuas
Txhawm rau txuas cov kav dej polypropylene nrog cov kav hlau, siv ob hom kev sib txuas:
- xov docking. Rau hom kev sib txuas no, ib qho tshwj xeeb adapter yog siv - threaded coupling. Nws yog qhov tsim nyog rau kev ua haujlwm nrog cov kav dej uas muaj txoj kab uas hla tsawg dua 40 mm. Hauv qhov no, fittings uas muaj qhov sib txawv tsim yog siv. Qhov no yog ib qho adapter los ntawm cov yeeb nkab hlau mus rau ib qho polypropylene, uas muaj cov xov ntawm ib sab rau fastening ib tug hlau yeeb nkab, thiab nyob rau lwm yam, lub tes tsho du rau ib tug polypropylene. Yog tias tsim nyog, cov duab ntawm qhov haum tuaj yeem hloov pauv los ntawm cua sov nws nrog lub tsev plaub hau tshuab kom kub ntawm +140 ° C. Tsis tas li ntawm kev muag khoom yog fittings rau txuas cov kav dej sib txawv, rau khoov thiab tig.
-
Flange kev twb kev txuas. Hom kev sib txuas no raug xaiv thaum siv cov kav dej loj loj. Ib tug feature ntawm no tsim yog muaj peev xwm ntawm disassemble nws yog hais tias tsim nyog. Lub flange yog ib qho collapsible, muaj ib lub tes tsho rau cov yeeb nkab hlau, lub hau rau kev hloov mus rau cov yas thiab cov bolts.
Flange rau hlau thiab polypropylene kav - Threadless txuas. Lub clutch no muaj ntau qhov chaw:
- steel lossis cam khwb cia hlau lub cev;
-ob lub txiv ntoo nyob ntawm ob sab ntawm lub cev;
- plaub lub txiv ntoo hauv cov kab sib txuas;
- cov ntaub qhwv roj hmab uas ua cov ntsaws ruaj ruaj (lawv tus lej yuav txawv).
Yuav tsum muaj cov cuab yeej thiab cov khoom siv
Ua ntej ua haujlwm ncaj qha, yuav tsum npaj cov cuab yeej thiab cov khoom siv. Txhawm rau txuas cov kav dej polypropylene nrog cov kav hlau koj xav tau:
- polypropylene kav ntawm txoj kab uas hla;
- 90 ° thiab 45 ° kaum;
- clips kho cov kav dej polypropylene ntawm phab ntsa;
- drill;
- grinder nrog discs rau hlau;
- xov cutter - ib lub cuab yeej rau kev txiav xov ntawm cov kav hlau, cov txheej txheem suav nrog ib qho kev ua haujlwm, uas yog ib puag ncig thav duab ntawm lub tog raj kheej luv luv, txheej txheej tuag lossis tuag cutters, tuav, clamps, pliers thiab lwm yam cuab yeej zoo sib xws kuj tseem muaj;
- fum tape;
- tawm;
- silicone sealant;
- couplings (feem ntau yog siv Asmeskas 1/2), fittings, flanges;
- txiab tshwj xeeb;
- roulette;
- muab xaum;
Technology rau kev txuas polypropylene kav nrog hlau kav
Koj tuaj yeem ua txhua txoj haujlwm koj tus kheej. Hauv qhov no, koj yuav tsum ua tib zoo xaiv tag nrho cov ntsiab lus ntawm kev tsim yav tom ntej. Nws tseem pom zoo kom kawm cov lus qhia ntawm cov kws tshaj lij:
- tsis txhob overtighten bolts thiab txiv ntseej, vim qhov no tuaj yeem ua rau tawg hauv cov polypropylene;
- koj yuav tsum xyuas kom meej tias tsis muaj burrs thiab cov ntsiab lus ntse ntawm ib feem ntawm cov fittings rau cov kav hlau, vim tias lawv tuaj yeem ua rau puas tsuaj rau cov qauv polypropylene (yog tias pom muaj qhov tsis xws luag, qhov saum npoo yuav tsum tau ntxuav nrog ib qho kev puas tsuaj. file);
- thaum hloov kho cov cua sov, nws raug nquahu kom hloov cov roj hmab gasket nrog silicone.
Txhim kho threaded fittings
Yuav ua txoj haujlwm no koj yuav tsum ua raws li cov lus qhia:
- Tshem tawm qhov sib txuas uas twb muaj lawm los ntawm cov hlau ntawm kev sib txuas lus. Yog tias qhov no tsis tuaj yeem ua tau, koj tuaj yeem txiav tawm ib lub yeeb nkab, tom qab ntawd siv roj rau cov saw txiav, thiab tom qab ntawd siv xov txiav los ua cov xov tshiab.
- So cov xov ntawm qhov haum rau cov kav hlau nrog cov ntaub qhwv, muab cov ntaub nplaum nplaum los yog khi rau saum, thiab tom qab ntawd npog nrog ib txheej ntawm silicone sealant. Koj yuav tsum nteg lub sealant raws cov xov.
- Ntsia rau ntawm qhov haum. Kev siv tus yuam sij hauv qhov no tsis pom zoo, vim muaj kev pheej hmoo tias qhov no yuav tawg vim muaj zog ntau dhau. Koj tuaj yeem nruj qhov haum rau cov kav dej tom qab qhib qhov system.
Txoj kev no zoo tshaj plaws thaum txhim kho cov kav dej ntawm cov khoom sib txawv ntawm kev khoov thiab khoov.
Thaum siv hom kev sib txuas ntawm cov yeeb nkab no, nws yuav tsum nco ntsoov tias cov khoom siv polypropylene tuaj yeem nthuav dav thaum raug qhov kub thiab txias (piv txwv li, yog tias lub tshuab cua sov tau teeb tsa). Qhov no txhais tau hais tias thaum cov kav dej nyob hauv qab txheej ntawm plaster, nws raug pom zootawm qhov sib txawv ntawm 1 cm siv tubular rwb thaiv tsev. Qhov no muaj tseeb tshwj xeeb rau cov chaw nyob ib puag ncig bypasses thiab tees.
Siv flanges
Flange mounting thev naus laus zis yog qhov yooj yim. Txhawm rau txuas cov kav dej koj xav tau:
- Txiav tawm lub raj hlau ntawm qhov chaw ntawm kev sib txuas yav tom ntej. Kev txiav yuav tsum yog raws li qhov ua tau, uas koj tuaj yeem siv lub grinder.
- Muab lub flange rau ntawm qhov no, tom qab ntawd nruab cov roj hmab gasket. Qhov kawg yuav ua raws li lub foob.
- Push lub flange hla cov roj hmab gasket.
- Ua cov yeeb yam zoo sib xws nrog cov yeeb nkab polypropylene.
- Txuas ob lub flanges nrog cov bolts haum. Qhov no yuav tsum tau ua kom sib npaug thiab sib hloov, thaum nws raug pom zoo los xyuas kom meej tias tsis muaj kev cuam tshuam thiab kev hloov pauv ntawm qhov chaw. Txhob thawb dhau.
Siv cov xov tsis sib txuas
Ua ntej koj yuav tsum tau npaj gaskets, ntxhua khaub ncaws thiab txiv ntseej, uas yuav tsum sib haum mus rau ntu ntu ntawm cov raj xa dej. Tom qab ntawd, koj tuaj yeem txuas ntxiv nrog kev teeb tsa ntawm kev sib txuas yam tsis muaj xov raws li cov lus qhia hauv qab no:
- Los ntawm cov txiv ntoo, los ntawm cov khoom siv thiab cov tshuab ntxhua khaub ncaws, ntxig cov hlau thiab cov kav dej polypropylene rau hauv qhov sib txuas ntawm ob sab.
- Txhim cov txiv ntoo kom nres, thaum xyuas kom cov gaskets clamped rau qhov nres.
Kev sib txuas zoo li no, raws li thev naus laus zis, yuav ruaj khov thiab muaj zog.
Koj tuaj yeem koom nrog cov ntsiab lus ntawm cov kav dej ntawm koj tus kheej. Ua li no, koj yuav tsum xaiv qhov chaw ntawm txoj cai loj, nrogqhov no yuav tsum twv yuav raug hu mus rau hauv tus account lub cheeb ntawm cov kav dej (hlau thiab polypropylene kav tib lub sij hawm, vim hais tias muaj kev sib txuas cov ntsiab lus nrog cov connectors sib txawv ntawm ob sab), npaj cov cuab yeej thiab ua raws li cov lus qhia. Kev sim khiav ntawm lub kaw lus yuav pab txiav txim siab qhov zoo ntawm kev sib txuas.
