Nhau - Ductile Iron Pipe Production process: Rigorous process yekukanda Mapaipi emhando yepamusoro

Mukugadzira maindasitiri emazuva ano, mapaipi esimbi e ductile anoshandiswa zvakanyanya mukugovera mvura, kudhiraivha, kutapurirana gasi uye mamwe minda nekuda kweakanakisa makinika zvimiro uye nekupokana nekuora. Kuti uve nechokwadi chemhando yepamusoro uye kuvimbika kwepamusoro kwepombi dzesimbi dze ductile, maitiro avo ekugadzira anofanirwa kunyatso kudzora uye kunyatsogadziriswa. Kubva pakugadzirira uye spheroidization yesimbi yakanyungudutswa, kusvika centrifugal kukanda, annealing, uye kupedzisa maitiro senge zinc spraying, kugaya, hydraulic pressure test, simende lining uye asphalt spraying, zvese zvinongedzo zvakakosha. Ichi chinyorwa chichasuma maitiro ekugadzirwa kweDuctile Cast Iron Pipezvakadzama, uye kuratidza maitiro ekuona kuti pombi yega yega inogona kusangana nepasirese mwero uye chaiyo yekushandisa zvinodiwa kuburikidza nesainzi manejimendi uye yepamberi yehunyanzvi nzira, uye nekupa yakavimbika zvivakwa vimbiso kune akasiyana mainjiniya mapurojekiti.

1. Kugadzirira kweSimbi Yakanyungudutswa
Yakanyungudutswa Iron Kugadzirira uye Spheroidization: Sarudza yemhando yepamusoro yekukandira nguruve simbi seyakagadzirwa, senge yemhando yepamusoro ductile casting yenguruve iron, ine maitiro epasi P, yakaderera S, uye yakaderera Ti. Zvinoenderana neiyo dhayamita yepombi kuti igadzirwe, izvo zvinofananidzira zvigadzirwa zvinowedzerwa kune yepakati frequency yemagetsi vira, iyo inogadzirisa simbi yakanyungudutswa uye nekuipisa kune tembiricha inodiwa nemaitiro, uyezve inowedzera spheroidizing mumiriri we spheroidization.
Kupisa Iron Quality Control: Mukuita kwekugadzirwa kwesimbi yakanyungudutswa, kunaka uye tembiricha yechinhu chimwe nechimwe chinodzorwa zvakanyanya. Choto chega chega uye bhegi rega rega resimbi yakanyungudutswa inofanirwa kuongororwa neiyo yakananga kuverenga spectrometer kuona kuti simbi yakanyungudutswa inosangana zvizere nezvinodiwa zvekukanda.

2. Centrifugal Casting
Mvura-yakatonhorera Metal Mold Centrifuge Casting: Mvura-yakatonhorera simbi mold centrifuge inoshandiswa kukanda. Kupisa-kupisa kwesimbi yakanyungudutswa inoramba ichidururwa muhombe yepombi inotenderera inomhanya. Pasi pekuita kwe centrifugal force, simbi yakanyungudutswa inogoverwa zvakaenzana pamadziro emukati epombi mold, uye simbi yakanyungudutswa inokurumidza kusimba nekutonhodza kwemvura kuti iite ductile iron pombi. Mushure mekunge kukanda kwapera, pombi yakakandwa inoongororwa nekukasira uye kuyerwa kuitira kukandira hurema kuti ive nechokwadi chemhando yepombi yega yega.
Annealing Treatment: The castIron Tubeinozoiswa muchoto chekuvharisa chekurapa kwekubvisa kushushikana kwemukati kunogadzirwa panguva yekukanda uye kugadzirisa metallographic chimiro uye michina yepombi. .
Performance Testing: Mushure mokunge annealing, iyo ductile iron pipe inotarisirwa kune dzakatevedzana dzakasimba bvunzo dzekuita, kusanganisira indentation bvunzo, chitarisiko bvunzo, flattening test, tensile test, hardness test, metallographic test, etc. Mapaipi asingasviki zvinodiwa acharaswa uye haazopindi muchirongwa chinotevera.

3. Kupedza
Zinc Spraying: Iyo ductile iron pombi inobatwa ne zinc nekushandisa high-voltage electric spray machine. Iyo zinc layer inogona kuumba firimu rekudzivirira pamusoro pepombi kuti iwedzere kusimba kwepombi. .
Kukuya: AnokwanisaDuctile Iron Drainage Pipezvinotumirwa kuchiteshi chechitatu chekukuya kuti chiongororwe chitarisiko, uye socket, spigot uye mudhuri wemukati wepombi yega yega zvinokwenenzverwa nekucheneswa kuti ive nechokwadi chekudzika uye kupera kwepombi uye kuvharwa kweiyo interface.
Hydrostatic Test: Mapombi akagadziridzwa anoiswa muyedzo yehydrostatic, uye kudzvanywa kweyedzo ndeye 10kg/cm² yakakwira kupfuura ISO2531 standard yepasi rose uye yeEuropean standard, kuitira kuti ive nechokwadi chekuti mapombi anogona kumira zvakakwana mukati memukati uye kusangana nekumanikidza zvinodiwa mukushandisa chaiko. .
Cement Lining: Rusvingo rwemukati rwepombi rwakaputirwa necentrifugally nesamende nekaviri-station simenti lining machine. Iyo simende yakashandiswa dhaka yakaongororwa yakasimba yemhando uye kudzora chiyero. Iyo yose yekuputira maitiro inodzorwa nekombuta kuti ive nechokwadi chekufanana kwemhando uye kugadzikana kweiyo simenti lining. Mapaipi akaiswa simende anoporeswa sezvinodiwa kuti anyatso kusimbaradza simende. .
Asphalt Spraying: Mapombi anorapwa anotanga kupiswa pamusoro, uye ipapo asphalt inopfapfaidzwa nekaviri-chiteshi otomatiki sprayer. Iyo asphalt yekuputira inowedzera kuwedzera anti-corrosion kugona kwepombi uye inowedzera hupenyu hwebasa hwemapombi. .
Kuongorora Kwekupedzisira, Kurongedza uye Kuchengeta: Mapombi akapfapfaidzwa neasphalt anoongororwa kwekupedzisira. Mapombi anonyatsokodzera chete ndiwo anogona kumwaya mavanga, obva aiswa mukati ochengetwa sezvinodiwa, achimirira kutumirwa kunzvimbo dzakasiyana kuti ashandiswe.
