Kodi mukukumana ndi kutayikira kapena kufooka mu makina anu opachikira mapaipi? Kugwiritsa ntchito chitoliro cha HDPE molakwika ndi chifukwa chofala cha kulephera kwa makina komanso kuchedwa kwa ntchito.

Mapaipi a HDPE amalumikizidwa pogwiritsa ntchito mitundu itatu ikuluikulu ya zolumikizira:kusakanikirana kwa matako, kusakanikirana kwa magetsi, ndi zolumikizira zamagetsi. Njira zolumikizira zimapanga cholumikizira chokhazikika, cha monolithic chomwe chili cholimba ngati chitoliro chokha, pomwe zolumikizira zamagetsi zimapereka chisindikizo chochotseka komanso chamakina.

Kudziwa mayina a zipangizo zolumikizira ndi chiyambi chabe. Woyang'anira zinthu wapamwamba kwambiri monga Carlos amamvetsetsa kuti luso lenileni lili pakudziwa njira yolumikizira yomwe mungagwiritse ntchito pazochitika zilizonse. Chidziwitsochi ndi chomwe chimateteza ndalama zanu, chimatsimikizira kuti polojekiti yanu ndi yolondola, komanso chimamanga mbiri yodalirika.

Kodi mumalumikiza bwanji mapaipi a HDPE pamodzi?

Kodi mukuvutika ndi kulumikizana kwa mapaipi kovuta kapena kosadalirika? Cholumikizira choipa ndicho cholumikizira chofooka kwambiri mu dongosolo lililonse la mapaipi, chomwe chikuyembekezera kuyambitsa mavuto mtsogolo.

Mumalumikiza mapaipi a HDPE pogwiritsa ntchito welding yotenthetsera (butt fusion kapena electrofusion) kuti pakhale mgwirizano wokhazikika, wosataya madzi, kapena ndi makina opondereza ma dayamita ang'onoang'ono kapena maulumikizidwe osakhalitsa komwe sipakufunika zida zapadera. Njira iliyonse imagwira ntchito yosiyana.

Kuchokera pa zomwe ndakumana nazo ku Pntek, ndaona ndekha momwe kusankha njira yoyenera yolumikizira kumasungira nthawi ndi ndalama zambiri pamalopo. Carlos akathandiza kontrakitala kusankha pakati pa chogwirizira chosavuta chokonzera pang'ono ndi kusakaniza matako a payipi yayikulu, sakungogulitsa gawo lake; akugulitsa yankho lomwe limatsimikizira kupambana kwanthawi yayitali.

Kusakanikirana kwa Matako

Iyi ndi njira yodziwika kwambiri ya mapaipi akuluakulu a HDPE. Njirayi ndi yosavuta. Makina apadera amagwira malekezero awiri a mapaipi molunjika bwino. Mbale yotenthetsera imayikidwa pakati pawo, ndikusungunula malekezerowo kufika pa kutentha kwina. Mbaleyo imachotsedwa, ndipo malekezero osungunuka amakanikizidwa pamodzi pansi pa mphamvu yolamulidwa. Zimazizira kuti zikhale chitoliro chimodzi chopitilira. Cholumikizira ichi sichimataya madzi konse ndipo chimakhala cholimba ngati chitoliro choyambirira.

Kusakanikirana kwa Maginito

Njira iyi ndi yabwino kwambiri pokonza kapena m'malo opapatiza pomwe makina olumikizira matako sangagwirizane. Ma electrofusion fittings ali ndi waya wozungulira mkati mwake. Mapeto a mapaipi amalowetsedwa mu fitting, ndipo purosesa ya electrofusion imatumiza mphamvu yamagetsi ku mawaya. Kutentha kuchokera ku mawaya kumasungunula mkati mwa fitting ndi kunja kwa chitoliro, ndikuziphatikiza pamodzi kukhala cholumikizira cholimba komanso champhamvu.

Zopangira Zopondereza za Makina

Pa mainchesi ang'onoang'ono (nthawi zambiri osakwana mainchesi 4 kapena 110mm), zolumikizira zokakamiza ndi njira yabwino komanso yosavuta. Sizifuna zida zapadera. Mumangoyika nati ndi mphete yogwirira pa chitolirocho, kuyika chitolirocho m'thupi loyenerera, ndikulimbitsa natiyo. Izi zimakanikiza mphete ya O kuti ipange chisindikizo chosalowa madzi. Ndi yachangu, yosavuta, ndipo ingathe kuchitidwa ndi wogwira ntchito aliyense.

Kodi HDPE ndi yabwino kuposa PVC?

Kodi mukukambirana za HDPE ndi PVC pa ntchito yanu yotsatira? Kusankha zinthu molakwika kungayambitse mavuto pakukhazikitsa ndi makina omwe sangakwaniritse zomwe amayembekezera.

Palibe chilichonse mwa izi chomwe chili 'chabwino' padziko lonse. HDPE ndi yabwino chifukwa cha kusinthasintha kwake, kukana mankhwala, komanso kulimba kwa kuzizira mpaka kusungunuka, zomwe zimapangitsa kuti ikhale yoyenera kuyikidwa popanda ngalande komanso mikhalidwe yovuta. PVC ndi yabwino chifukwa cha kulimba kwake, mphamvu zake zokoka, komanso mtengo wake wotsika, zomwe zimapangitsa kuti ikhale chisankho chabwino kwambiri pakugwiritsa ntchito mapaipi amadzi ndi kupanikizika.

Monga mtsogoleri wa Pntek, kampani yomwe imachita bwino kwambiri pa PVC, ndaona mapulojekiti ambiri omwe PVC imapereka magwiridwe antchito abwino komanso phindu. Komabe, ndine woyamba kuvomereza kuti HDPE ndiye chida choyenera pantchitoyo. Katswiri ngati Carlos amadziwa kuti njira yabwino yotumikira makasitomala ake ndikuwatsogolera kuzinthu zoyenera zosowa zawo, osati kungokankhira chinthu chimodzi pamwamba pa china.

Kusinthasintha vs. Kulimba

Kusiyana koonekeratu ndi kusinthasintha. Kutha kupindika kwa HDPE kumalola kuti iikidwe mozungulira ngodya popanda zowonjezera ndipo kumapangitsa kuti ikhale yoyenera kuyika popanda ngalande (kuikoka pansi). PVC ndi yolimba kwambiri, zomwe zimapangitsa kuti ikhale yolimba kwambiri poikamo ndipo imaletsa kugwa pamitengo yayitali komanso yowongoka.

Njira Yolowera ndi Mtengo

Ichi ndi chinthu chachikulu kwa Carlos ndi makasitomala ake. PVC imalumikizidwa ndi ma primer osavuta komanso otsika mtengo komanso simenti yosungunulira, kapena ndi ma bell end okhala ndi gasket. Zipangizozi ndizosavuta ndipo ntchito yake ndi yachangu. HDPE imafuna zida zokwera mtengo komanso zapadera zolumikizira kutentha komanso ogwira ntchito ovomerezeka, zomwe zimawonjezera mtengo woyambira wa projekiti komanso zovuta zake. Ponena za mtengo wazinthu, PVC nthawi zambiri imakhala yotsika mtengo kuposa HDPE ya kalasi yofanana ya pressure.

Kodi HDPE imayesedwa mu OD kapena ID?

Kodi kuyitanitsa chitoliro cholakwika kungasokoneze dongosolo lanu lonse la ntchito? Kusamvetsetsa momwe chitoliro cha HDPE chimayezedwera kungayambitse mapaipi ndi zolumikizira zosagwirizana, zomwe zingawononge nthawi ndi ndalama.

Miyeso ya mapaipi a HDPE imachokera pa diameter yakunja yolamulidwa (OD). Izi ndizofunikira chifukwa njira zolumikizirana zimafuna malo akunja a mapaipi ndi kuyika kuti zigwirizane bwino kuti chitsulo chigwire bwino ntchito.

Iyi ndi mfundo yaukadaulo yomwe imasiyanitsa anthu osaphunzira ndi akatswiri. Ndikamalankhula ndi manejala wogula zinthu monga Carlos ndipo amatchula chitoliro pogwiritsa ntchito OD ndi SDR yake, ndimadziwa kuti ndikuchita ndi katswiri. Amamvetsetsa kuti kulondola kumeneku si nambala yokha pa pepala lofotokozera; ndi chinsinsi cha dongosolo lodalirika komanso lopanda kutayikira. M'mimba mwake (ID) mkati mwake mumasintha kutengera makulidwe a khoma, koma OD nthawi zonse imakhala yofanana pa kukula kwa chitoliro.

Chifukwa Chake Kukula Kwakunja Ndikofunikira

Kusakaniza kutentha kumagwira ntchito mwa kusungunula pamwamba pa chitoliro ndi pamwamba pa mkati mwa cholumikizira (kapena pamwamba pa chitoliro china). Kuti izi zigwire ntchito, pamwamba pake payenera kukhala pabwino. Mwa kusunga OD yosasintha, opanga amaonetsetsa kuti chitoliro chilichonse cha kukula kwina chikugwirizana ndi makina aliwonse olumikizira kapena olumikizira, mosasamala kanthu za kupanikizika kwake.

Kumvetsetsa SDR (Standard Dimension Ratio)

• Kodi ndi chiyani:SDR ndi chiŵerengero cha m'mimba mwake wakunja kwa chitolirocho ndi makulidwe ake a khoma.
• Fomula:SDR = OD / Kukhuthala kwa Khoma
• Tanthauzo lake: A pansiNambala ya SDR imatanthauza achokhuthalaKhoma la chitoliro. Khoma lokhuthala limatha kuthana ndi kupanikizika kwakukulu. Mwachitsanzo, chitoliro cha SDR 11 chili ndi khoma lokhuthala komanso kupanikizika kwakukulu kuposa chitoliro cha SDR 17 cha kukula komweko. Carlos ayenera kudziwa zonse ziwiri OD ndi SDR zomwe zimafunikira kuti ayitanitse chitoliro choyenera malinga ndi zosowa za makasitomala ake.

Kodi ndi mtundu wanji wa cholumikizira chomwe chimagwiritsidwa ntchito mu chitoliro cha HDPE?

Kodi mukufuna malo olumikizira mapaipi omwe mungabise ndikuiwala? Kuopa kutuluka kwa madzi mtsogolo kuchokera kumalo olumikizirana ndi nkhawa yayikulu kwa makontrakitala ndi eni makina.

Cholumikizira chachikulu komanso champhamvu kwambiri chomwe chimagwiritsidwa ntchito pa chitoliro cha HDPE ndi cholumikizira cha matako. Njira yolumikizira kutentha iyi imapanga kulumikizana kwa monolithic (kopanda msoko) komwe sikutulutsa madzi konse ndipo nthawi zambiri kumakhala kolimba kuposa chitolirocho chokha.

Lingaliro la dongosolo la "monolithic" ndi losintha zinthu. Zimatanthauza kuti mukupanga chitoliro chimodzi chachitali, chopitilira popanda kulumikizana kwamakina komwe kungamasuke kapena kuwonongeka pakapita nthawi. Kwa wogula ngati Carlos, kukhala ndi mwayi wopereka dongosolo lomwe limachotsa chiopsezo cha kulephera kwa mafupa ndi mwayi waukulu wampikisano. Ndi lonjezo lalikulu lodalirika kwa nthawi yayitali.

Kupanga Dongosolo Losataya Madzi Kwenikweni

Cholumikizira cholumikizidwa ndi matako sichili ngati cholumikizira cholumikizidwa ndi guluu kapena cholumikizidwa; ndi kukonzanso kwa chinthucho chokha. Maunyolo a polima ochokera kumapeto onse a mapaipi amasakanikirana pamodzi ali osungunuka ndikuzizira kuti apange chidutswa chimodzi cholimba. Mkanda waung'ono womwe umapangidwa mkati ndi kunja kwa chitoliro ndi chizindikiro chowoneka bwino cha weld yopambana. Cholumikizira ichi ndi cholumikizidwa kwambiri kotero kuti chimasunga kusinthasintha ndi mphamvu ya chitolirocho bwino.

Chifukwa Chake Iyi Ndi Muyezo Wagolide

Mtundu uwu wa cholumikizira ndi wodalirika kwambiri kotero kuti ndi muyezo wofunikira pa ntchito zofunika kwambiri monga mizere yogawa gasi wachilengedwe, mapaipi amadzi amphamvu kwambiri, komanso mayendedwe a mankhwala m'mafakitale. Cholumikiziracho chimadziletsa chokha, zomwe zikutanthauza kuti sichingasweke chifukwa cha kupanikizika kapena kuyenda pansi. Izi zimachotsa kufunikira kwa ma block kapena zotchingira zokwera mtengo zomwe zimafunikira pamakina ena ambiri a mapaipi, zomwe zimachepetsanso ndalama zoyikira komanso zovuta.

Mapeto

Makina a HDPE amadalira kusakanikirana kapenazolumikizira zoponderezaKulumikizana kwa matako kumapanga cholumikizira champhamvu kwambiri komanso chosatulutsa madzi. Kusankha pakati pa HDPE yosinthasintha ndi PVC yolimba komanso yotsika mtengo kumadalira kwathunthu zomwe polojekitiyi ikufuna.
