Nhau - Ductile Iron Pipe: Chinhu Chinokosha paMasisitimu eMapombi Emazuva Ano

Ductile Iron Pipe, inogadzirwa nesimbi yakakandwa sehwaro hwechinhu. Isati yadururwa, magnesium kana rare earth magnesium nezvimwe zvinosanganisa simbi inonyungudutswa zvinowedzerwa kusimbi yakanyungudutswa kuti graphite iite spheroidize, uye pombi inogadzirwa kuburikidza nemaitiro akaomarara. Kusiyana kwesimbi inonyungudutswa ndekwekuti yakawanda kana yese yegraphite inonyeredzwa iri muchimiro chedenderedzwa, uye hunhu uhwu hwechimiro hunovandudza zvikuru mashandiro echinhu chacho. Mushure mekunamirwa, chimiro chemetallographic cheChubhu yesimbi nhemaiferrite pamwe nehuwandu hushoma hwepearlite, uye hunhu hwemuchina hwakanaka.

Nhoroondo yebudiriro yeDuctile Iron Chubhuizere nekuvandudzwa kwezvinhu zvitsva. Mukupera kwema1980 nekutanga kwema1990, vachitarisana nekuvharirwa kwetekinoroji yekugadzira mapaipi esimbi ecentrifugal uye mamiriro akaoma ekubvumidza patent, 2672nd Factory yeChinese People's Liberation Army (yakatangira Xinxing Casting Pipe) yakashinga kuita basa rekutsvagisa nekusimudzira yakazvimiririra. Muna 1993, pombi yekutanga yesimbi yecentrifugal ductile muChina yakabudirira kuburitswa kubva pamutsetse wekugadzira, zvichiratidza kuti nyika yangu yasvika padanho rekutanga mundima iyi, uye zvakatora makore masere chete kuti ipedze maitiro ekuvandudza kwemakore makumi mana enyika dzekuMadokero. Nhasi, Xinxing Casting Pipe yave mugadziri wemapaipi esimbi ecentrifugal ane simba uye akasimba pasi rose, uye yavewo chikamu mukugadzirwa kwemazinga emapaipi esimbi epasi rose, ichikurudzira kufambira mberi kweindasitiri yemapaipi esimbi eductile.

Mapaipi esimbi eDuctile ane maitiro akasiyana-siyana ekushanda

1. Simba Rakakwirira uye Kusimba Kwakanaka: Mapaipi esimbi ane simba guru, uye simba rawo rakavandudzwa zvikuru kana tichienzanisa nemapaipi esimbi akaumbwa. Nekuti graphite yakapararira muchimiro chedenderedzwa, kupatsanurwa kwematrix kunoderedzwa, zvichiita kuti paipi isanyanya kutyoka kana yaiswa pakumanikidzwa kukuru uye kuroverwa. Panguva imwe chete, inewo kusimba kwakanaka, ine kureba kwakakura kupfuura 10%, uye inogona kuchinjika pasi pevhu, kufamba kwevhu nezvimwe zvinhu kusvika pamwero wakati. Hazvisi nyore kukuvara nekushanduka, izvo zvinovandudza kuvimbika kwekushanda kwenetwork yemapaipi.

2. Kuramba Kwakasimba Kwengura: Kuburikidza nenzira dzakasiyana-siyana dzekurapa dzinodzivirira ngura, dzakadai sekupenda neasphalt, simende, epoxy coal tar, epoxy ceramic lining, aluminate cement, sulfate cement coating uye polyurethane coating, mapaipi esimbi ane ductile anogona kudzivirira ngura kubva kune zvakasiyana-siyana. Ingave inoshandiswa kutakura gasi, mvura yepombi, kana yekuburitsa tsvina, inogona kuchengetedza kushanda kwakasimba munzvimbo dzakasiyana-siyana dzakaoma, kuwedzera hupenyu hwebasa repaipi, uye kuderedza mari yekugadzirisa.
3. Kuvhara Kwakanaka: Muromo wepombi unoshandisa nzira inochinjika, iyo inogona kuchinjika kuchinjika uye kuchinja mukati meimwe nzvimbo, kugadzira mugumisiro wakanaka wekuvharira pachikamu chekubatanidza pombi, uye kudzivirira kubuda kwemvura zvinobudirira. Panguva imwe chete, maitiro ekugadzira pombi pachayo akanyatsojeka anovimbisa kuenderana kwesoketi, anowedzera kuvandudza mashandiro ekuvharira, uye anovimbisa kushanda kwakachengeteka kwesystem yepombi.
4. Kuiswa Kuri Nyore: Zvichienzaniswa nedzimwe mapaipi, huremu hwemapaipi esimbi ane ductile hushoma, uye maitiro ekuisa ari nyore. Chimiro chayo chinochinjika chinobatsira vashandi vekuvaka kuita basa rekubatanidza, zvichideredza nguva yekuisa uye simba rebasa. Panzvimbo yekuvaka, kuiswa kwemapaipi kunogona kupedzwa nekukurumidza pasina michina yakaoma uye mainjiniya vane hunyanzvi, izvo zvinopfupikisa kutenderera kwepurojekiti uye zvinovandudza kushanda zvakanaka kwekuvaka.
5. Kushanda Kwakanaka Kwekudzivirira Kutonhora: Munzvimbo dzinotonhora, mashandiro emapaipi ekudzivirira kuoma kwechando akakosha. Mapaipi esimbi ane mwero wakati wekudzivirira kuoma kwechando. Chero bedzi asiri nharaunda yakaoma zvakanyanya, hapana kuputika kwechando. Izvi zvinoita kuti ishandiswe zvakanyanya mukugovera mvura, kudziyisa uye mamwe mapaipi munzvimbo dzinotonhora dzekuchamhembe, zvichipa masevhisi akavimbika kune vagari nemabhizinesi.

Ductile Iron Water Pipezvave zvinhu zvakakosha uye zvakakosha zvepombi mukuvaka zvivakwa zvemazuva ano nekushanda kwazvo kwakanaka. Kubva pakuwanikwa kwemvura muguta nekuyerera kwemvura kusvika pakufambisa gasi, kubva pakugadzirwa kwemaindasitiri kusvika kumapurojekiti ekuchengetedza mvura, mapaipi esimbi ane ductile anoita basa guru muminda yakasiyana-siyana uye akapa mipiro yakakosha mukuona kuti hupenyu hwevanhu hwakanaka uye kusimudzira hupfumi. Nekufambira mberi kuri kuramba kuchienderera mberi uye kuvandudzwa kwetekinoroji, mashandiro emapaipi esimbi ane ductile acharamba achivandudzwa, uye huwandu hwekushandiswa huchawedzerwa. Acharamba achipenya mukuvaka zvivakwa mune ramangwana.
