Mapaipi olumikizirana ndi makina nthawi zonse amakhala ngati malo oyamba kulephera. Gasket yotuluka kapena nati yopondereza yotayirira ingayambitse kuwonongeka kwakukulu, kukonza kokwera mtengo, komanso nthawi yogwira ntchito.

Cholumikizira cha socket fusion ndi cholumikizira cha thermoplastic (monga HDPE kapena PP-R) chomwe chimalumikizidwa ku chitoliro pogwiritsa ntchito heat welding. Chida chapadera chimasungunula kunja kwa chitoliro ndi mkati mwa cholumikiziracho, zomwe zimakankhidwira pamodzi kuti zikhale chidutswa chimodzi, chokhazikika, chosatulutsa madzi.

Ndikukumbukira ndikulankhula ndi kasitomala amene ankayang'anira ntchito yaikulu yothirira. Nthawi zonse ankakumana ndi vuto la kutuluka kwa madzi chifukwa cha kayendedwe ka nthaka komanso kusintha kwa mphamvu ya madzi. Pamene ndinamuphunzitsa za lingaliro lakusakanikirana kwa soketi, chinasintha zinthu kwambiri. Lingaliro lakuti cholumikiziracho chingakhale cholimba ngati, kapena cholimba kuposa, chitolirocho chinathetsa vuto lake lalikulu lodalirika. Ndi ukadaulo wosavuta, koma mukamvetsetsa momwe chimagwirira ntchito, mumawona zabwino zake zazikulu. Tiyeni tifufuze mwatsatanetsatane.

Kodi cholumikizira cha PE chimapangidwa ndi chiyani kwenikweni?

Mumawona "PE" pa cholumikizira koma simukudziwa tanthauzo lake la mphamvu. Kusankha cholumikizira chopangidwa kuchokera ku pulasitiki yolakwika kungayambitse kulephera kosayembekezereka mukapanikizika.

Cholumikizira cha PE chimapangidwa ndi polyethylene. Pa mapaipi opanikizika, nthawi zambiri izi zimakhala High-Density Polyethylene (HDPE), chinthu cholimba, chosinthasintha, komanso chosagwira mankhwala chomwe chimagwiritsidwa ntchito kwambiri monga kugawa madzi ndi mpweya.

Polyethylene ndi gulu la mapulasitiki, koma si mitundu yonse yomwe imapangidwa mofanana. Chofunika kwambiri ndi kuchulukana. Kuchulukana kukakhala kwakukulu, kumakhala kolimba komanso kolimba. Pa zolumikizira za socket zomwe zimagwiritsidwa ntchito m'madzi kapena mapaipi amafakitale, timagwiritsa ntchitoHDPE, nthawi zambiri imatchulidwa kuti PE100. Mtundu uwu uli ndi kulemera kwakukulu kwa mamolekyulu, zomwe zimapangitsa kuti ukhale wolimba kwambiri ku kukakamizidwa, kugundana, ndi mankhwala. Ndi chinthu chomwecho chomwe chimagwiritsidwa ntchito pa mapaipi okha. Izi zimatsimikizira kuti mukaphatikiza Pntek PE yolumikizira ndi chitoliro cha PE, mukulumikiza zinthu ziwiri zofanana. Kugwirizana kumeneku ndiye maziko opangira weld yangwiro, ya monolithic yomwe idzakhalapo kwa zaka zambiri popanda kuwonongeka. Ndi chinthu chopangidwa kuti chitetezeke kwa nthawi yayitali.

Mitundu Yodziwika ya Polyethylene

Ndi mitundu yanji ya mapaipi omwe mungalumikizane ndi PE fusion?

Muli ndi chida cholumikizira, koma simukudziwa mtundu wa mapaipi apulasitiki omwe chimagwira ntchito nawo. Kuyesa kulumikiza zinthu zosagwirizana kumabweretsa vuto lalikulu.

Kusakaniza kwa PE kumagwiritsidwa ntchito polumikiza zinthu zofanana za thermoplastic. Kwapangidwira makamaka mapaipi a polyethylene (PE) monga HDPE ndi MDPE, komanso mapaipi a polypropylene (PP-R). Simungathe kuphatikiza mapulasitiki osiyanasiyana monga PE ndi PVC.

Mfundo yakuwotcherera kosakanikiranaNdi yosavuta: mukusungunula ndi kupanganso pulasitiki. Kuti izi zigwire ntchito, magawo awiri omwe mukulumikiza ayenera kukhala ndi kapangidwe ka mankhwala kofanana komanso kutentha kofanana. Ichi ndichifukwa chake mutha kungophatikiza "ngati ndi ngati." Ntchito yodziwika kwambiri ndi kujowinaChitoliro cha HDPEku zida za HDPE zamakina omwe amafuna kudalirika kwathunthu. Izi zikuphatikizapo mapaipi amadzi a m'matauni omwe ali pansi pa nthaka, mizere ya mankhwala yamakampani amphamvu kwambiri, ndi maukonde ogawa gasi wachilengedwe. Njira yofanana yolumikizira mapaipi a PP-R ndiyo njira yodziwika bwino yolumikizira mapaipi a PP-R, omwe ndi otchuka kwambiri pa mapaipi amadzi otentha ndi ozizira mkati mwa nyumba. Chofunika kwambiri ndichakuti kuphatikiza kumapanga dongosolo lopanda msoko, koma pokhapokha ngati chitoliro ndi zipangizo zolumikizira zikugwirizana bwino.

Kodi mumalumikiza bwanji mapaipi a HDPE ndi zolumikizira pamodzi?

Njira yolumikizira ma fusion welding ingaoneke yovuta. Kusuntha kamodzi kolakwika, ndipo mutha kupanga cholumikizira chofooka chomwe chingalephereke pambuyo pake, zomwe zingawononge chidaliro pa ntchito yanu yokhazikitsa.

Kuti muphatikize HDPE, mumatenthetsa pamwamba pa chitoliro ndi mkati mwa cholumikiziracho ndi chida kwa nthawi yoikika. Kenako, mumazikanikiza pamodzi ndikuzigwira mpaka zitazizira. Izi zimapangitsa kuti cholumikiziracho chikhale chokhazikika komanso cholumikizidwa.

Njirayi ndi yolondola koma yosavuta ngati mutsatira njira zomwe zafotokozedwa.

1. Kukonzekera:Choyamba, dulani mbali ya chitolirocho bwino bwino. Kenako, yeretsani mbali ya chitolirocho ndi mkati mwa soketi yolumikizira kuti muchotse dothi kapena mafuta.
2. Kutentha:Chida cholumikizira soketi chili ndi ma adapter otenthetsera a kukula kosiyanasiyana kwa mapaipi. Kankhirani chitoliro mbali imodzi ndi cholumikizira mbali inayo nthawi imodzi. Nthawi yotenthetsera ndi yofunika kwambiri ndipo imadalira kukula kwa chitoliro.
3. Kulowa:Nthawi yotenthetsera ikatha, chotsani mwachangu komanso bwino zigawo zonse ziwiri kuchokera pa chidacho. Kankhirani chitolirocho molunjika mu soketi ya cholumikizira mpaka chitaima. Musachipotoze.
4. Kuziziritsa:Gwirani cholumikiziracho bwino kwa nthawi yodziwika bwino yoziziritsira. Izi zimathandiza kuti pulasitiki yosungunuka ikhale yolimba kwambiri.

Kutsatira nthawi yoyenera yotenthetsera ndi kuziziritsa ndikofunikira kuti pakhale chotenthetsera chodalirika.

N’chifukwa chiyani cholumikizira cha fusion chili champhamvu kuposa cholumikizira cha makina?

Mumagwiritsa ntchito zolumikizira zamagetsi chifukwa n'zosavuta kuyika. Koma mukudziwa kuti gasket iliyonse ndi ulusi uliwonse ndi malo omwe angalephereke omwe angamasulidwe pakapita nthawi.

Cholumikizira chosakanikirana chimakhala champhamvu chifukwa chimachotsa cholumikizira chonse. Chitoliro ndi cholumikiziracho zimakhala pulasitiki imodzi yolimba. Kulumikizana kwa monolithic kumeneku kulibe ma gaskets oti awonongeke kapena mabolts oti asunuke, zomwe zimapangitsa kuti chikhale cholimba kuposa chitolirocho chokha.

Cholumikizira chamakina chimalumikiza magawo awiri, koma cholumikizira cha fusion chimawagwirizanitsa. Taganizirani za unyolo wachitsulo; umakhala wolimba ngati cholumikizira chake chofooka kwambiri. Mu payipi yokhala ndi zolumikizira zamakina, zolumikizirazo ndi zolumikizira zofooka. Zimadalira kukanikiza kwa gasket ya rabara kapena kukangana kwa ulusi kuti apange chisindikizo. Izi zitha kukhudzidwa ndi kugwedezeka, kusintha kwa kutentha, ndi kuyenda kwa nthaka. Cholumikizira cha fusion chilibe zofooka izi. Njira yosungunula ndikupanganso HDPE imatanthauza kuti dera la cholumikiziracho limakhala pulasitiki yolimba yopanda msoko. Tikachita mayeso othamanga mu labotale yathu, khoma la chitoliro nthawi zonse limalephera cholumikiziracho chisanathe. Ichi ndichifukwa chake pa ntchito zofunika kwambiri, zololera kutayikira pansi pa nthaka kapena zoyikidwa mu konkire, fusion ndiyo chisankho chokhacho chodalirika.

Kusakanikirana ndi Kulumikizana kwa Makina

Mapeto

Kusakaniza kwa socket kumapanga cholumikizira chabwino kwambiri mwa kulumikiza chitolirocho ndikuchiyika mu chidutswa chimodzi cholimba. Izi zimachotsa malo otayikira, zomwe zimapangitsa kuti ikhale njira yodalirika kwambiri ya machitidwe a PE ndi PP-R.
