HDPE chitoliro: unsembe wa manja awo, makamaka unsembe ndi malangizo

mipope Polyethylene ali mosalekeza chifukwa cha makhalidwe kwambiri zakuthupi. Kunadetsa ntchito tsiku ndi tsiku HDPE chitoliro. Unsembe tingachite ndi manja awo, ngati kuchita chilichonse ndi malamulo. Izo sikutanthauza luso.

makhalidwe zakuthupi

Anthu ankafuna kwambiri chifukwa HDPE chitoliro chifukwa mkulu khalidwe la zinthu:

• kutentha osiyanasiyana - -50 ⁰ C kuti +60 ⁰ C;
• kukana kuti acidic ndi zamchere TV;
• elasticity mkulu ndi mphamvu;
• otsika matenthedwe madutsidwe;
• Polyethylene si wochititsa magetsi.

Ntchito mipope

Kunyumba kapena pa kanyumba a mipope HDPE anapangidwa:

• sewerage ndi ngalande;
• madzi;
• kotunga mpweya kunyumba;
• chingwe njira kwa Kulumikizana magetsi.

Kusankha machubu

Pakuti abwino madzi kuikira chitoliro tikhale ndi awiri osati choposa 60 mamilimita ndi khoma makulidwe a 4 mm. Iwo ayenera anaikira kufinya machitidwe a madzimadzi mu dongosolo n'chozama kupitirira 1 MPa. Ubwino ndi yonena za zitsulo dzimbiri ndi kukoma kwa madzi. Ngati chofunika akonzekeretse otentha madzi, m'pofunika kudziwa kuti pa kutentha 80 ⁰ C polyethylene kumafeŵetsa ndi pa zina polera iwo amayamba kusungunuka. Pa nkhani imeneyi ayenera kusankhidwa, kalasi PE80. Pakuti mipope madzi otentha Angagwiritsidwenso zaikidwa kapena Pe-RT PN20, iwo kupirira Kutentha kwa 110 ⁰ C. Kuti zinthu izi amoyo ndi chokwanira.

Kodi kusiyanitsa mapaipi madzi ndi zofuna za ufulu. Kuti zinthu zachilendo opaleshoni atengedwa ngalande Bay mamita 25 yaitali ndi osachepera 2 mm khoma makulidwe. Ngati mzere waukulu akuthamanga opanikizika wabwino ndipo ali m'mimba mwake wamkulu kuposa 25 mm, amatengedwa ngati mpopi inchi chitoliro. Mulimonsemo, kuchotsa ayenera kukhala gawo ang'onoang'ono kuposa magetsi apo.

Njira ya mipope HDPE

Pamaso unsembe, kusankha njira mogwirizana, kumene kungakhale motere:

1. Yofunika - electrofusion kapena mbuyo kuwotcherera. Pawiri akamagwira mphamvu mofanana chitoliro yokha.
2. Gawa njira - wayaka, psinjika ndi kugwirizana flange. Chotero piping machitidwe mosavuta anasonkhana ndipo ankaiphwasula, n'zotheka kuti tikonze kapena unsembe mu malo zolimba. Kugwirizana anapangidwa kudzera zovekera lapansi.

njira kugwirizana amusankha malingana zifukwa zotsatirazi:

• chitoliro diameters;
• mtundu wa ntchito; ufulu otaya, kuthamanga, cabling;
• ntchito mavavu zinthu zosiyanasiyana ndi diameters osiyana;
• gawo Kufikika;
• pamaso pa zida kuwotcherera.

The cholimba kwambiri analandira welded ndi kugwirizana flanged. Malaya yamazinga ndi chizindikiro cha kugonjetsedwa ndi nkhawa. Unsembe wa HDPE mapaipi madzi ndi zovekera psinjika kawiri kawiri zimachitika mu minda kunyumba kachitidwe ulimi wothirira.

Kugwirizana anafooka - zinayambira. Iwo ntchito okha mapaipi sanali kuthamanga koma pamene kugwirizana ndi welded.

zovekera psinjika kwa mapaipi HDPE: ogwiritsa

Pakuti HDPE mipope ntchito zovekera makamaka pulasitiki, koma palinso mitundu wolimba ngati chitsulo, chitsulo, mkuwa, ndi mkuwa. Iwo amasiyana kapangidwe ndi akhoza welded, yamazinga, ndi atolankhani kugwirizana. Pakuti mipope pulasitiki ali makamaka ntchito zovekera psinjika, mmene fixation ikuchitika clamping kugawanika mphete pulasitiki wolimba ndi notches ndi kusindikiza - kumanga kusindikiza mphete.

Ngati zipangizo zina polumikiza, psinjika zovekera ndi a mitundu angapo:

• lumikiza - kwa kugwirizana mapaipi a awiri ofanana ndi malangizo;
• kusintha - chifukwa akhomere malekezero a mipope, ndi diameters amene ali osiyana (a kusintha 'zitsulo-Pe ");
• Anabweza ngodya - ikuchitika pa kupindika dongosolo 45-120 ^0;
• tees, mitanda - kulenga nthambi;
• cholumikizira - chipangizo cha kulumikiza paipi kwa payipi;
• pulagi - kuti anatsekera chitoliro malekezero.

Pamaso yolozera madzi ayenera choyamba jambulani chithunzi ndi zovekera zake zonse ndi mavavu. Chitoliro kukodzedwa amamuchititsa amapotoza kotero wotetezedwa ndi clamps kapena mbamuikha ku boma kukodzedwa kwa masiku 2.

Ngati anasankhidwa kuti unsembe wa HDPE chitoliro unsembe nthawi zambiri ndi zovekera psinjika.

1. chitoliro The Kadulidwa kukula Napempha kwa chida chapadera. Mukhoza kugwiritsa ntchito hacksaw zonse, koma kumapeto chomwecho pangotsala ndi Achotsa burrs.
2. Dzenje limagwirizana calibrator monga mawonekedwe ake chowulungika ndi zosayenela. chamfer kunja uli pa mapeto.
3. molondola thupi koyenera chikugwirizana ndi chitoliro, kotero kuti kuwononga zisindikizo mphira. Kubzala kudzakhala kosavuta ngati inu moisten Mphambano.
4. Manja omangika mgwirizano mtedza. Mukhoza kugwiritsa ntchito chinsinsi kupereka yogwirizana zofunika zikayamba.
5. Ndondomeko chachiwiri chitoliro akubwerezedwa.

psinjika kugwirizana zovekera conveniently ntchito, pamene yowalongera unsembe wa mapaipi HDPE mu dziko. Kachitidwe n'zosavuta kuti asonkhane m'chaka pa malowo ndi dismantle m'dzinja.

Pulagi-mu kugwirizana mu malo zolimba, sikuti. Pali yabwino ntchito kuwotcherera magetsi ndi anamanga-muzitentha. Kulumikizitsidwa chitoliro koyenera 2, inatuluka ndi adamulowetsa, ndipo Kutentha amapezeka kuwotcherera kupanga chimodzi-chidutswa msonkhano. Mtengo ndi okwera chipangizo, koma njira ndi bwino ndipo kawirikawiri amagwiritsidwa ntchito.

Ngakhale kuti akhoza dismantling mu zovekera psinjika ayenera m'malo zisindikizo mphira pamene reinstalling. Izi adzaonetsetsa kudalirika mkulu wa kamangidwe.

kugwirizana flange

Pamene anaika HDPE chitoliro ogwiritsa kwa m'mimba mwake 40 mamilimita ali makamaka anachita kudzera mwa flanges zitsulo. Kuti tichite zimenezi, kudula nsonga ya chitoliro wodula pa ngodya ufulu kamangidwe yotsirizidwa. Kenako welded malaya pulasitiki ndi matabwa, ndipo iwo anapereka zitsulo flanges. Njira ina ndi kusonkhana chitoliro psinjika flange kukapempha yosalala polima gawo la olowa. Ndiye, flange wamba, amene Ufumuyo ndi zikhomo ndi akapichi ndi chidutswa ofanana wokwera pa mapeto a chitoliro zitsulo.

kugwirizana Flanged amalola mavavu ndi, owongolera, mavavu ndi mipope pakati pawo.

welded kugwirizana

Monga mankhwala zitsulo akhoza welded HDPE chitoliro. Unsembe manja kubala mothandizidwa ndi zipangizo zina zapadera ndi Kutentha magetsi olowa.

1. Yolimidwa Mphambano, ndipo akukonzekera zida kuwotcherera.
2. Ikani kuwotcherera magawo.
3. mipope ali anakonza nsagwada za makina kuwotcherera ndi wokhazikika. Malekezero a umakaniko kukonzedwa.
4. Heaters amene anaika pakati machubu, imene dera isungunuke.
5. Malekezero a kuthamanga yafupika anakhalabe mpaka yozizira.
6. Mapaipi ndi yotengedwa tatifupi lapansi.

Unsembe ndalama mipope HDPE ndi kuwotcherera zimadalira awiri, koma mtengo wa 63 mamilimita ndi mtengo chomwecho zambiri 200 rubles. kwa olowa.

Pamene ntchito lumikiza magetsi ndalama unsembe ndi mofanana mbuyo kuwotcherera, koma mtengo wake ndi apamwamba. Motero, ndalama kupanga ali wamkulu.

mayesero hayidiroliki

Operability wa anasonkhana chitoliro madzi ndi kufufuzidwa ndi kudzaza madzi 2 h. Ndiye, kuthamanga mu dongosolo liukitsidwa ndipo anakhalabe pa 30 min. payipi ndi chipikisheni kwa kuchucha.

Mu ntchito boma la dongosolo ndi mosalekeza kuunikira. Pamene anasonkhana bwino izo ntchito nthawi yokwanira.

Zolakwa pa mipope msonkhano HDPE

1. Nkofunika kuganizira patsogolo liniya wa chitoliro ndi chifukwa cha kutentha. Ngati inu muiwale izo, mapaipi mkati Voteji kuposa wabwinobwino, amene amachepetsa moyo utumiki wawo.
2. zopambana kwambiri mtunda pakati anchorages amachititsa sagging ngalande kuti kumabweretsa linalephera msanga.
3. Mapaipi ndi manowa yekha ndi kutchinjiriza.
4. Kuti anapanga padziko condensate pa kudyetsa ofunda kapena ozizira conduits madzi insulated.
5. Pamene ogwiritsa ndi koyenera mfutizo kwa chitoliro ku siteji analowa. Pamene chivindikiriro nati si mapeto, kenako mwamphamvu anakankhira mu cholumikizira chubu, akhoza kulowa kwambiri zokwanira. Pamene unsembe unapangidwa mipope HDPE ndi manja ake mu dziko kachitidwe ulimi wothirira, kuchucha si owopsa koma ndi zosavomerezeka kwa madzi zoweta. Mosaganizira zotsatira zake milandu onse ndikofunikira kuti akonze kugwirizana zolimba.
6. Pa-kumangika adaputala kuchiwonongeko awo kapena amalowetsa ziyangoyango malo unsembe.

Pomaliza

Pamene anaika HDPE chitoliro, kusonkhana zachitika makamaka ndi zovekera kuwotcherera kapena psinjika. Phunziro kwa malamulo a kugwirizana khwekhwe adzakhala zolimba ndi cholimba kwa zaka zambiri.
