Nhau - Ndeupi mutsauko pakati pepombi dzesimbi dze ductile uye dzakajairwa dzakakandwa simbi pombi?

Pane misiyano yakawanda pakatiDuctile Iron Pipes uye vakajairwa vakakandwaIron Pipes maererano nezvinhu, kuita, maitiro ekugadzira, kutaridzika, mamiriro ekushandisa uye mutengo, sezvinotevera:

Material
Ductile iron pipe: Chinhu chikuru ndeye ductile iron. Pahwaro hwesimbi yakajairwa, spheroidizer uye inoculant inowedzerwa kushandura graphite musimbi yakakandwa kubva paflake kuenda kudenderedzwa.
Mutopota wesimbi wakajairika: Zvinhu zvacho isimbi yakakandwa, uye graphite yayo inogoverwa mumaflakes.

Performance
Simba uye kuoma: Kusimba kwekusimba uye kusimba kwemapombi esimbi ane ductile akakwira zvakanyanya kupfuura ayo emapombi esimbi akajairwa. Iko kusimba kwesimba remapombi esimbi ductile anogona kazhinji kusvika 400-900MPa, nepo simba rekusimba reakajairwa simbi pombi kazhinji 150-300MPa. Ductile iron mapaipi ane maitiro akanaka ekupikisa, haasi nyore kutyora, uye anogona kumirisana nemasimba makuru ekunze uye deformation.
Corrosion resistance: Dzese dzine imwe dhigirii yekuramba kuonda, asi mapaipi esimbi ane ductile anoshingirira mukuora nekuda kwechimiro chawo chakaomarara uye anowanzo rapwa akazara anti-corrosion kurapwa, sekunge zinc coating pamadziro emukati nekunze, asphalt pendi, nezvimwe.
Kuisa chisimbiso:Ductile Iron Tubeshandisa inochinjika machinjiro, senge rubber ring seals, iyo inogona kuchinjika kune imwe dhigirii yepombi deformation uye kutamiswa, kuve nekuvharika kuri nani, uye inogona kudzivirira zvinobudirira mvura nemhepo kubuda. Mapaipi epombi akajairwa anokandwa haana kusimba uye haana chisimbiso chisina kunaka.

Nzira yekugadzira
Ductile iron pombi: Nekuwedzera spheroidizers uye inoculants kusimbi yakanyungudutswa, uyezve kugadzira ne centrifugal casting. Iyi nzira inoita kuti chimiro chepombi chakakandwa chiwedzere uye chakafanana, uye hutano hwakagadzikana.
Mapombi esimbi akajairika: Kazhinji, kukanda jecha kana kuenderera mberi kwekukanda maitiro anoshandiswa, uye maitiro ekugadzira ari nyore, asi kunaka uye kufanana kwekuita kwekukandwa kwayo hakuna kunaka sepombi dzesimbi dze ductile.

Chitarisiko
Ductile iron pombi: Nzvimbo yacho inenge yakatsetseka, kukora kwemadziro kwakafanana, uye kutenderera kwemuviri wepombi kwakanaka.
Mutopota wesimbi wakajairika: Nzvimbo yacho inenge yakaoma, uye panogona kunge kune zvimwe zvirema zvakadai semakomba ejecha uye pores, uye kukora kwemadziro epombi kunogona kunge kusina kufanana.

Maitiro ekushandisa
Ductile iron pipe: Inoshandiswa zvakanyanya mukupihwa kwemvura yemumaguta, dhiraivha, kutapurirana gasi, maindasitiri pombi masisitimu uye mamwe minda ane zvakakwirira zvinodiwa pakuita kwepombi. Ductile iron pombi ndiyo inosarudzika pombi zvinhu mukufambiswa kwemvura kure-kure, kutapurirana kwemvura yakakwira-kudzvanywa uye zviitiko zvine huwandu hwemhando yemvura.
Mutopota wesimbi wakajairika: Nekuda kwekuita kwayo kwakadzikira, inonyanya kushandiswa mune dzimwe nguva uko zvinodiwa pombi isiri yakakwirira, senge kuvaka kwemvura, kudiridza kusingamanikidzike uye mamwe masisitimu.

Price
Ductile iron pipe: Nekuda kwemaitiro akaomarara ekugadzira uye zvinodikanwa zvakakwirira zvezvinhu zvakabikwa uye zvigadzirwa zvekugadzira, mutengo unodhura uchienzaniswa neyakajairwa simbi pombi. Nekudaro, mutengo wayo wakazara une zvakanakira mukushandiswa kwenguva refu nekuda kwehupenyu hwayo hurefu uye mutengo wakaderera wekugadzirisa.
Mutopota wesimbi wakajairika: Mutengo wacho wakachipa uye wakakodzera kune mamwe mapurojekiti ane mashoma mabhajeti uye hapana zvinoomesesa zvinodiwa pakuita kwepombi.

Muchidimbu, pombi dzesimbi dzesimbi uye dzakajairwa simbi pombi dzinoratidza misiyano iri pachena mune akawanda makiyimisheni. Ductile iron mapaipi anoita basa rakakosha muminda yakawanda yakakosha ine zvinodikanwa zvakanyanya pamhando yepombi uye kugadzikana nekuda kwehukuru hwadzo hwezvinhu, kuita kwakanakisa uye tekinoroji yekugadzira. Kunyangwe mapombi esimbi akajairwa ari pasi zvishoma mukuita, anotorawo nzvimbo mune chaiwo einjiniya einjiniya mamiriro nekuda kwemitengo inokwanisika. Mukugadzirwa kweinjiniya chaiyo uye mapurojekiti ekuisa pombi, kunyatsonzwisisa mutsauko uripo pakati pezviviri uye kunyatsosarudza mapombi akakodzera zvichienderana nemamiriro ekushandisa chaiwo, zvinodiwa pakuita uye zvipingamupinyi zvebhajeti ndiyo kiyi yekuona kufambira mberi kwakanaka kweprojekiti, kushanda kwakagadzikana kwenguva refu uye kuwedzera mabhenefiti ehupfumi.
