Chitoliro chachitsulo cha ductile ndi mtundu wa chitoliro chachitsulo choponyedwa.Pankhani ya khalidwe, kalasi ya spheroidization ya chitoliro chachitsulo chiyenera kuyendetsedwa mpaka 1-3 giredi (spheroidization rate> 80%), kotero kuti makina azinthuzo asinthidwa bwino, ndi chikhalidwe cha chitsulo ndi chitsulo. katundu zitsulo.Mapangidwe a metallographic a annealed ductile iron pipe ndi ferrite kuphatikiza pearlite pang'ono.Ili ndi katundu wamakina abwino, kukana kwa dzimbiri, ductility wabwino, kusindikiza bwino, kuyika kosavuta, ndipo imagwiritsidwa ntchito makamaka popereka madzi, kutumiza gasi, kutumiza mafuta, etc. m'mabizinesi am'matauni, mafakitale ndi migodi.
Kuchuluka kwa graphite yozungulira kumagawidwa pa matrix a ferrite ndi pearlite.Malinga ndi mainchesi osiyanasiyana mwadzina ndi zofunikira pakukweza, gawo la ferrite ndi pearlite pamapangidwe a matrix ndi osiyana.Gawo la pearlite lokhala ndi mainchesi ang'onoang'ono nthawi zambiri siliposa 20%, ndipo lalitali lalikulu nthawi zambiri limayendetsedwa pafupifupi 25%.
Pkachitidwe mwa ductile iron pipe
Chitoliro chachitsulo cha ductile ndi mtundu wa chitsulo chosungunuka, chomwe ndi aloyi yachitsulo, carbon ndi silicon.Graphite mu spheroidal graphite cast iron ilipo mu mawonekedwe a spheroidal graphite.Nthawi zambiri, kukula kwa graphite ndi 6-7, ndipo kalasi ya spheroidization ya chitoliro choponyedwa imayenera kuyang'aniridwa ku 1-3 (spheroidization rate ≥ 80%) ponena za khalidwe.Chifukwa chake, zida zamakina zazinthuzo zakhala zikuyenda bwino, ndi chikhalidwe chachitsulo komanso chitsulo.Mapangidwe a metallographic a annealed ductile iron pipe ndi ferrite kuphatikiza pearlite pang'ono, ndipo mawonekedwe ake amakina ndi abwino.
Chitoliro chachitsulo chimatchedwa centrifugal ductile iron pipe.Iwo ali ndi chikhalidwe cha chitsulo, ntchito zitsulo, kukana dzimbiri bwino, ductility wabwino, zotsatira zabwino kusindikiza, unsembe zosavuta, ndipo makamaka ntchito madzi, kufala gasi, kufala mafuta, etc. mu tauni, mafakitale ndi migodi mabizinesi.Ndilo kusankha koyamba kwa mapaipi operekera madzi okhala ndi ntchito zotsika mtengo.Poyerekeza ndi chitoliro cha PE, nthawi yoyika chitoliro chachitsulo cha ductile ndi chosavuta komanso chofulumira kuposa chitoliro cha PE, ndipo kupanikizika kwapakati ndi kunja kumakhala bwino pambuyo poika;Kuchokera pakuwona kwa airtightness ndi kukana kwa dzimbiri, chitoliro cha graphite cha spheroidal graphite pambuyo pa kukhazikitsa chimakhala bwino, komanso kukana kwa dzimbiri kungathenso kupitsidwanso ndi njira zosiyanasiyana zolimbana ndi dzimbiri;Kuchokera pamawonedwe a hydraulic performance, chifukwa mafotokozedwe a chitoliro chachitsulo cha ductile nthawi zambiri amatanthauza m'mimba mwake wamkati, mafotokozedwe a chitoliro cha PE nthawi zambiri amatanthauza m'mimba mwake, chifukwa pansi pamikhalidwe yomweyi, chitoliro chachitsulo cha ductile chimatha kukwaniritsa kuthamanga kwambiri;Kuchokera pakuwona ndalama zonse zoyika ndi kukonza, chitoliro chachitsulo cha ductile chimakhala ndi mtengo wabwinoko.Khoma lamkati limapakidwa ndi zinc, simenti yamatope odana ndi dzimbiri, etc.
Mechanical katundu mwa ductile iron pipe
Mphamvu zocheperako: 420/MPa
Mphamvu zochepa zokolola: 300/MPa, elongation yochepa 7%
Miyezo: GB/T13295-2013, ISO2531-2009
Kutalika: DN80-DN2600
Malingaliro osankhidwa mwa ductile iron pipe
1. Kusankhidwa kwa mipope yachitsulo ya ductile kudzakhazikitsidwa pazikhalidwe zenizeni za malo ogona, ndipo mawonekedwe a mawonekedwe a mapaipi owongoka ndi zopangira zidzasankhidwa.
2. Mphete ya rabara nthawi zambiri imapangidwa ndi NBR, SBR, EPDM ndi zipangizo zina.
3. Kusankhidwa kwa zokutira: sankhani chovala choyenera malinga ndi momwe zilili mkati ndi kunja pakugwiritsa ntchito.Chophimba chamkati chomwe chilipo ndi epoxy resin, polyurethane mkati ndi kunja, chophimba cha filimu ya PE ndi zinthu zina zatsopano za chitoliro chachitsulo cha ductile, ndipo ntchito yake iyenera kumveka mwatsatanetsatane posankha.
Ubwino ndi kuipa kwake mwa ductile iron pipe
Amwayi
Mapaipi achitsulo amagwiritsidwa ntchito pamapaipi apakatikati komanso otsika (omwe amagwiritsidwa ntchito pansi pa 6MPa).Mapaipi achitsulo a ductile ali ndi ntchito yotetezeka komanso yodalirika, kuwononga pang'ono, kumanga kosavuta komanso kofulumira komanso kukonza bwino, komanso kukana dzimbiri.Mapaipi a "Yandun" omwe angopangidwa kumene atha kugwiritsidwa ntchito pomanga mopanda ngalande ndipo amagwiritsidwa ntchito kwambiri pomanga mapaipi kudutsa mitsinje, misewu ndi nyumba.Mapaipi otsatizana a "Saizin" amagwiritsa ntchito njira yapadera yopopera mankhwala a zinc aluminium alloy kunja kuti apititse patsogolo kulimba kwa mapaipi kangapo, ndipo amagwiritsidwa ntchito kwambiri pomanga dothi lochita dzimbiri.
Dmwayi
Nthawi zambiri, sichimagwiritsidwa ntchito pamapaipi apamwamba kwambiri (pamwamba pa 6MPa).Chifukwa thupi la chitoliro ndi lolemera kwambiri, makina ayenera kugwiritsidwa ntchito pakuyika.Ngati madzi akutuluka pambuyo poyesa kuthamanga, mipope yonse iyenera kukumbidwa, mipope iyenera kukwezedwa mpaka kutalika komwe ingathe kuikidwa muzitsulo, ndipo zingwe ziyenera kuikidwa kuti madzi asatayike.
We JINBAICHENG ism'modzi mwa opanga odziwika bwino, wogulitsa kunja, wogulitsa masheya, wokhala ndi masheya komanso ogulitsaductile iron pipe.Tili ndi makasitomala ochokera ku Mexico, Turkey, Pakistan, Oman, Israel, Egypt, Arab, Vietnam, Myanmar, German, etc.
