Uri kusangana nematambudziko ekudonhedza mvura here kana kuti hauna simba musystem yako yekuisa mapaipi? Kushandisa nzira isiriyo yekuisa mapaipi eHDPE ndicho chikonzero chinowanzoita kuti pave nekukundikana kunodhura kwesystem uye kunonoka kweprojekiti.

Mapaipi eHDPE akabatanidzwa achishandisa mhando nhatu huru dzezvibatiso:kusangana kwemagaro, kusanganiswa kwemagetsi, uye michina yekumanikidza. Nzira dzekubatanidza dzinogadzira chisungo chinogara chiripo, chakasimba sepombi pachayo, nepo michina yekumanikidza ichipa chisimbiso chinobviswa, chemuchina.

Kuziva mazita ezvishandiso zvemagetsi ingori mavambo chete. Maneja wepamusoro wekutenga saCarlos anonzwisisa kuti hunyanzvi chaihwo huri mukuziva kuti ndeipi yekuisa zvinhu muzvinhu zvipi. Ruzivo urwu ndirwo runodzivirira mari yako, runovimbisa kuvimbika kweprojekiti, uye runovaka mukurumbira wekuvimbika.

Ungabatanidza sei mapaipi eHDPE pamwe chete?

Uri kunetseka here nekubatana kwemapombi kwakaoma kana kusina kuvimbika? Jointi isina kunaka ndiyo link isina kusimba pane chero system yepombi, inomirira kukonzera matambudziko mangwana.

Unobatanidza mapaipi eHDPE nekushandisa heat welding (butt fusion kana electrofusion) kuti pave nechisungo chinogara kwenguva refu, chisingadonhedze mvura, kana ne mechanical compression fittings yedhayamita diki kana kubatanidza kwenguva pfupi uko pasina michina yakakosha inodiwa. Nzira imwe neimwe ine chinangwa chakasiyana.

Kubva pane zvakaitika kwandiri kuPntek, ndakaona nemaziso angu kuti kusarudza nzira chaiyo yekubatanidza kunochengetedza nguva nemari yakawanda panzvimbo iyi. Carlos paanobatsira mugadziri wezvinhu kusarudza pakati pechinhu chiri nyore chekugadzirisa chidiki uye kubatanidza mapaipi makuru, haasi kungotengesa chikamu chete; ari kutengesa mhinduro inoita kuti zvinhu zvibudirire kwenguva refu.

Kusanganiswa Kwemagaro

Iyi ndiyo nzira inonyanya kushandiswa pamapaipi eHDPE ane dhayamita hombe. Maitiro acho ari nyore. Muchina wakakosha unobata magumo maviri emapaipi akanyatsorongeka. Chitofu chinoiswa pakati pawo, chichinyungudutsa magumo acho kusvika patembiricha chaiyo. Chitofu chinobviswa, uye magumo akanyungudutswa anodzvanywa pamwe chete pasi pekumanikidzwa kwakadzorwa. Anotonhora kuti agadzire chidimbu chimwe chete, chinoenderera mberi chepombi. Chibatanidzo ichi hachibvi mvura zvachose uye chakasimba sepombi yekutanga.

Kusanganiswa kweElectromagnetic

Nzira iyi yakakodzera kugadzirisa kana munzvimbo dzakamanikana uko muchina wekubatanidza mabutt fusion usingakwane. Electrofusion fittings ine waya yakaiswa mukati mayo. Magumo emapaipi anoiswa mufitting, uye electrofusion processor inotumira magetsi kumawaya. Kupisa kunobva pawaya kunonyungudutsa mukati mefitting nekunze kwepaipi, zvichibatanidza pamwechete kuita joint yakasimba, yakasimba.

Kudzvanywa kweMichina

Kune dhayamita diki (kazhinji pasi pe 4 inches kana 110mm), ma "compression fittings" ndiwo mhinduro yakanaka uye iri nyore. Hazvidi michina yakakosha. Unongoisa nati ne "grip ring" pamusoro pepombi, woisa pombi mumuviri we "fitting", wobva wasimbisa nati. Izvi zvinodzvanya O-ring kuti zvigadzire chisimbiso chisingapindi mvura. Zvinokurumidza, zviri nyore, uye zvinogona kuitwa nechero mushandi.

HDPE iri nani pane PVC here?

Muri kukakavadzana pakati peHDPE nePVC pabasa renyu rinotevera here? Kusarudza zvinhu zvisiri izvo kunogona kukonzera matambudziko ekuisa zvinhu uye system isingasvike pakutarisira mashandiro.

Hapana chimwe chazvo chiri nani pasi rose. HDPE inopfuura nekureruka kwayo, inodzivirira makemikari, uye inogara kwenguva refu ichinyunguduka, zvichiita kuti ive yakakodzera kuiswa pasina migero uye mamiriro akaoma. PVC iri nani nekuda kwekuoma kwayo, simba rayo rekudhonza, uye mutengo wayo wakaderera, zvichiita kuti ive sarudzo yepamusoro yekushandisa mvura nekushandisa simba rekumanikidza.

Semutungamiri wePntek, kambani inobudirira muPVC, ndakaona mapurojekiti asingaverengeki apo PVC inopa chiyero chakakwana chekushanda uye kukosha. Zvisinei, ndini wekutanga kubvuma kuti HDPE ndiyo chishandiso chakakodzera basa racho. Nyanzvi saCarlos inoziva kuti nzira yakanakisa yekushandira vatengi vake ndeyekuvatungamira kune zvinhu zvakanakisisa zvinoenderana nezvavanoda, kwete kungosundira chimwe chigadzirwa pamusoro pechimwe.

Kuchinjika vs. Kuomarara

Musiyano uri pachena ndewekuchinjika. Kugona kweHDPE kukotama kunoita kuti iiswe pamakona pasina zvimwe zvinoiisa uye kunoita kuti ive yakakwana pakuisirwa pasina mugero (kuidhonza nepasi). PVC yakasimba zvikuru, izvo zvinoita kuti ive nesimba guru rekuviga uye inodzivirira kutsvedza pakumhanya kwenguva refu, kwakatwasuka.

Nzira yeKubatana uye Mutengo

Ichi chinhu chikuru kuna Carlos nevatengi vake. PVC yakabatanidzwa nema primer ari nyore, asingadhuri uye simende inonyungudutsa, kana nemagumo ebhero ane gasketed. Zvishandiso izvi zviri nyore uye basa rinoitwa nekukurumidza. HDPE inoda michina inodhura, yakasarudzika yekubatanidza kupisa uye vashandi vane certification, izvo zvinowedzera mutengo wekutanga uye kuoma kweprojekiti. Panyaya yemutengo wezvinhu, PVC inowanzo kudhura zvishoma pane HDPE yemhando imwechete yekumanikidza.

HDPE inoyerwa muOD here kana kuti muID?

Kuraira pombi isiriyo kunogona kukanganisa purogiramu yako yese yepurojekiti here? Kusanzwisisa kuti pombi yeHDPE inoyerwa sei kunogona kutungamira kumapombi asingaenderane nezvishandiso, zvichitambisa nguva nemari.

Zviyero zvepombi dzeHDPE zvakavakirwa padhayamita yekunze inodzorwa (OD). Izvi zvakakosha nekuti nzira dzekubatanidza dzinoda nzvimbo dzekunze dzepombi uye kuiswa kwayo kuti zvienderane chaizvo kuti pave nekunamira kwakanaka.

Iyi inyaya yehunyanzvi inoparadzanisa vagadziri vema "asina ruzivo" kubva kune nyanzvi. Pandinotaura nemaneja wekutenga akaita saCarlos uye iye anotsanangura pombi neOD neSDR yayo, ndinoziva kuti ndiri kubata nenyanzvi. Anonzwisisa kuti kunyatsojeka uku hakusi kungoverenga nhamba iri papepa re "spec" chete; ndiyo kiyi yesystem yakavimbika, isina kudonhedza mvura. Dhayamita yemukati (ID) ichachinja zvichienderana neukobvu hwemadziro, asi OD inogara yakafanana kune saizi yepombi yakapihwa.

Nei Dhayamita Yekunze Iri Chinhu Chinokosha

Kubatanidza kupisa kunoshanda nekunyungudutsa pamusoro pepombi nepamusoro pechibatiso (kana pamusoro pekunze kweimwe pombi). Kuti izvi zvishande, nzvimbo dzinofanira kuenderana zvakanaka. Nekuchengetedza OD isingachinji, vagadziri vanovimbisa kuti chero pombi yehukuru hwakati ichakwana chero muchina wekubatanidza kana wekubatanidza, zvisinei nekumanikidzwa kwayo.

Kunzwisisa SDR (Standard Dimension Ratio)

• Chii ichocho:SDR inhamba yedhayamita yekunze yepombi nehukobvu hwemadziro ayo.
• Fomura:SDR = OD / Ukobvu hwemadziro
• Zvinorevei: A pasiNhamba yeSDR zvinoreva agobvuRusvingo rwepombi. Rusvingo rwakakora runogona kubata kumanikidzwa kwakanyanya. Semuenzaniso, pombi yeSDR 11 ine madziro akakora uye kumanikidzwa kwakanyanya kupfuura pombi yeSDR 17 yehukuru hwakaenzana. Carlos anofanira kuziva zvese OD inodiwa uye SDR kuti aronge pombi yakakodzera zvinoenderana nezvinodiwa nevatengi vake zvekumanikidzwa.

Rudzii rwejoini rinoshandiswa mupaipi yeHDPE?

Uri kutsvaga pombi yekubatanidza mvura yaunogona kuviga wokanganwa here? Kutya kudonha kwemvura mune ramangwana kubva papombi dzakavigwa inyaya huru kune varidzi vemakondirakiti nevaridzi vemasystem.
