HDPE Pipe: kuisa maoko avo, kunyanya installation nemirayiridzo

Zvikwepa Polyethylene vari kuita zvinhu zvizhinji nokuda kwazvo zvechadenga zvinhu. Kuwedzera kushandiswa muupenyu hwezuva nezuva ndiko HDPE nenyere. Installation kunogona kuitwa nemaoko avo, kana kuti kuita zvose mitemo. It haatarisiri unyanzvi.

zvinhu unhu

The kudiwa zvikuru HDPE mutopota kunokonzerwa nemupristi unhu mashoko:

• tembiricha Range - -50 ⁰ C kuti +60 ⁰ C;
• kuramba acidic uye alkaline nhau;
• mukuru elasticity uye simba;
• pasi chafariz conductivity;
• Polyethylene hakusi muitisi weChidzidzo Magetsi.

Kushandiswa pombi

Kumba kana panguva yokurenda kuti mapaipi HDPE zvakaitwa:

• sewerage uye abudise;
• mvura;
• gasi wedzerai kumba;
• waya mukoto magetsi wiring.

The kusarudza sepombi

For potable mvura pombi dzemvura nenyere kuwana dhayamita isingadariki 60 mm norusvingo Ukobvu 4 mm. Vanofanira rakagadzirirwa kushanda kwokudzvinyirira kwomunhu mvura munyika dererei pane 1 MPa. An anobatsirwei kusavapo nesimbi ngura uye kuravidza mvura. Kana kunodiwa kushongedzera rinopisa mvura, zvakakosha kuziva kuti pane mumwe tembiricha 80 ⁰ C polyethylene dzinopomhodza uye pamusoro mberi vachisimudza rwunotanga itye. Panyaya iyi inofanira kusarudzwa, PE80 kugiredhi. For inopisa Zvikwepa mvura kunogona kunzi kana Pe-RT PN20, ivo kukunda kudziyisa kusvika 110 ⁰ C. To vapenyu ichi ezvinhu zvakakwana.

Vanofanira kusiyanisa pombi kuti mvura uye kumanikidzwa-free. For kwomuzvarirwo anodawo mamiriro vanotorwa mugero Bay mamita 25 refu pamwe zvinenge 2 mm rusvingo ukobvu. Kana mukuru mutsetse anomhanya pasi kufurirwa akanaka uye ane dhayamita kupfuura 25 neMM, rakundwa ive padiki mutopota pombi. Chero zvazvingava, kubviswa vanofanira kuva chikamu duku pane zvinonyatsorehwa magetsi.

Nzira Zvikwepa HDPE

Asati naro, kusarudza kubatana nzira, iyo angava sezvinotevera:

1. Chinokosha - electrofusion kana garo nomoto. Mukomboni yakawanikwa nesimba zvakafanana nomutopota pachayo.
2. Split nzira - kugabhuka, compression uye flange chokuita. Kwakadaro muridzo unoridzirwa hurongwa nyore vakaungana uye namambo mumwe chete dzakaparara, zvinokwanisika kugadzira kana kugadzwa zviri zvakasimba dzezvimwe. Connections dzinoitwa vachishandisa Fittings.

Connection nzira anosarudzwa zvichienderana zvinhu zvinotevera:

• mutopota diameters;
• kushanda ehove vakasununguka-aibuda, kumanikidzwa, cabling;
• kushandisa mavharuvhu dzakasiyana zvinhu uye diameters zvakasiyana;
• mugove svikika;
• kuvapo nomoto michina.

Chinonyanya yakasimba vari vakawana welded uye flanged kubatana. The Threaded ruoko nechisimbiso husingakwanisi mupfungwa. Kuisa pombi HDPE kuti mvura pamwe compression Fittings kunowanzoitwa mumba mapindu yokudiridzira enyika.

The dukusa kubatana - kugabhuka. Vari chete kushandiswa asiri nevezera mapaipi kunze kana kubatana iri welded.

Compression Fittings nokuti mapaipi HDPE: hwakawanda

For Zvikwepa HDPE vainyanya kushandisa mapurasitiki Fittings, asi panewo yakatsiga zvikuru dzakasiyana hwendarira, simbi, mhangura, nendarira. Avo akasiyana magadzirirwo rinogona welded, Threaded, pamwe womupepanhau kubatana. For epurasitiki pombi vari kudiwa kushandiswa compression Fittings, sezvamakaropafadzwa Kuda kutamba rinoitwa clamping kutsemura chindori zvakaoma mapurasitiki pamwe notches uye chisimbiso - tightening chisimbiso marin'i.

Kufanana nevamwe unobatanidza mano, compression Fittings vari anoverengeka siyana:

• coupling - nokuti maererano nokuda senyere pamusoro dhayamita zvakaenzana uye mirayiridzo;
• Kuchinja - nokuti fastening kumigumo nyere, asi diameters zvacho zvakasiyana (a kuchinja 'resimbi-Pe ");
• yokururamisa angled - rinoitwa pasi monyorora mamiriro 45-120 ^0;
• Tees, michinjikwa - kusika matavi;
• connector - zano kuti unobatanidza achiridza nyere hosipaipi;
• chivhariso - nokuti vakaisa mucherechedzo mutopota kumugumo.

Asati hwokutiparadza mvura yaivakwanira unofanira kutanga kuwana dhayagiramu zvose Fittings ayo uye mavharuvhu. The rakawedzerwa nyere ruchigona agure saka zviri richengetwe pamwe okusungisa kana akamanikidzwa kupinda rakawedzerwa mamiriro nokuda 2 kwemazuva.

Kana kusarudzwa nokuti kugadzwa HDPE mutopota chokugadza kakawanda kuitwa compression Fittings.

1. Nenyere unotemwa kuti aida ukuru chaihwo chokushandisa. Unogona kushandisa nguva hacksaw, asi panguva imwe chete mugumo sandara uye rinocheneswa cheek.
2. Hole dzichienderana calibrator sezvo zvayo denderedzwa chimiro nezvisingabvumwi. zvekunze chamfer riri pamagumo.
3. zvakarurama muviri zvakakodzera zvakabatana mutopota, kuti varege kuparadza rabha zvisimbiso. Planting zvichava nyore kana iwe inyorovese Junction.
4. Hands akasungirirwa mubatanidzwa nut. Unogona kushandisa kiyi kupa anodiwa kwokubatana kuti tightness.
5. Wechipiri nenyere nzira inodzokororwa.

Connection compression Fittings nyore kushandiswa, kana ane kuisa mapaipi HDPE munyika. The kwava nyore kuungana muchirimo panzvimbo uye gujunura yematsutso.

Chivhariso-mu kubatana mune zvakasimba dzezvimwe zvisina kuitwa. Pane nyore kushandisa yemagetsi nomoto pamwe pakuvara hita. Zvakabatana mutopota richishanda 2, pakwakanga kuri kusashanda, uye kudziyisa kunoitika nomoto kuti vaumbe ungano imwe-neimwe. Mutengo kumusoro mudziyo, asi nzira unoshanda uye rinoshandiswa.

Pasinei tinogona dismantling mu compression Fittings anofanira kutsiviwa rabha zvisimbiso kana reinstalling. Izvi zvichaita nechokwadi chakakwirira rakavimbika magadzirirwo.

flange kwokubatana

Kana waisa HDPE nenyere hwakawanda kuti 40 mm dhayamita iri kudiwa kuitwa pachishandiswa simbi flanges. Kuti aite izvi, akagura mupendero nenyere aricheke kuruoko rworudyi pakona yorusvingo kusvikira rapera marongerwo. Zvadaro vari welded epurasitiki ruoko namapuranga, vakagadzira simbi flanges. Imwe nzira iri kuungana nenyere compression flange hwokuchengetedza anotsvedzerera polymer chikamu muhudyu. Zvadaro, vanhuwo flange, izvo wanamatira kubudikidza nembambo uye nemabhaudhi ane yakafanana chimedu akatasva kuguma simbi nenyere.

Flanged kubatana anobvumira mavharuvhu, regulators, mavharuvhu uye pombi pakati pavo.

welded kwokubatana

Sezvakangoita simbi zvigadzirwa vanogona welded HDPE nenyere. Installation nemaoko kubereka uchibatsirwa chinokosha midziyo pamwe yemagetsi kudziyisa pejoinhi.

1. Yakagadzira panosangana, uye ari kugadzirira Welding michina.
2. Set nomoto parameters.
3. The pombi vari ngadzirambe dziri mushaya chakanamwa nomoto muchina uye zvakatinakira. Kumigumo mechanically kupatsanurwa.
4. Heaters vari akagadzawo pakati zvibereko, panopinda yakarukutika nharaunda.
5. Kumigumo shoma kufurirwa anodzokororwa kusvikira kutonhora.
6. Zvikwepa vari zvikaramba kubva clip.

Installation kunodyira Zvikwepa HDPE kubudikidza nomoto kunobva dhayamita, asi kune imwe kukosha 63 mm uye zvakafanana mutengo rinowanzova anenge 200 rubles. nokuti vagari.

Kana tikashandisa zvemagetsi coupling kugadzwa mari ndiwo zvakafanana nokuda garo nomoto, asi mutengo wake yepamusoro. Somugumisiro, kugadzirwa mutengo mukuru.

hydraulic miedzo

Operability of yakaunganidzwa mvura nenyere iri akadzivisa nokuzadza nemvura 2 h. Zvadaro, kwokudzvinyirira munyika chinomutswa uye inotarisirwa kuti 30 min. The Mapaipi ari yokuongororwa kuti idonhe.

Mukushanda mamiriro ezvinhu ari kuramba kuongororwa. Kana vakaungana zvakanaka zvichava kushanda kwenguva refu zvakakwana.

Zvikanganiso panguva Zvikwepa gungano HDPE

1. Zvakakosha kuti kufunga Linear kuwedzera nenyere pamigumisiro tembiricha. Kana iwe kanganwa nezvazvo, mukati nyere voltage kupfuura dzose, izvo zvinoderedza upenyu hwavo basa.
2. Kwazvo chinhambwe pakati anchorages chinokonzera sagging rukoronga inotungamirira ayo rokusamhanyira kukundikana.
3. Zvikwepa vari atadze chete kuputira.
4. Kuti haana kuumbwa pamusoro pemvura condensate, zvokudya inodziya kana inotonhora mvura yaisvitsa migero vari insulated.
5. Kana vanomhanyisa wakakodzera disassembled kuti nyere kusvika chemabhazi akapinda. Kana unscrewing kuti mupengo haisi kumagumo, uye ipapo zvakasimba kusingachakosheswi connector chubhu, unogona kupinda zvikuru zvakakwana. Kana installation ichinge chakagadzirwa mapaipi HDPE maoko ake munyika yokudiridzira mugadziriro, idonhe havana ngozi, asi zviri vaisafanira mumhuri mvura. Pasinei nemigumisiro mune zvose zviitiko zvinokosha kusika zvakasimba kubatana.
6. Over-tightening adapteri zvinotungamirira kukuparadzwa kwavo kana zvadzikira Mapedhi naro nzvimbo.

mhedziso

Kana waisa HDPE mutopota, kuungana zvinoitwa kunyanya nokuda nomoto kana compression Fittings. Pasi mitemo kubatana setup achava zvakasimba uye hunogara kwemakore akawanda.
