Menya byinshi kubyerekeye umuyoboro w'icyuma

Brief

Umuyoboro wicyuma ni ubwoko bwicyuma.Kubijyanye nubuziranenge, urwego rwa spheroidisation yicyuma gisabwa kugenzurwa kugeza ku cyiciro cya 1-3 (igipimo cya spheroidisation> 80%), bityo imiterere yubukanishi bwibikoresho ubwayo yarushijeho kuba myiza, hamwe na kamere yicyuma na ibiranga ibyuma.Imiterere ya metallografiya yumuyoboro wicyuma uhujwe ni ferrite wongeyeho umubare muto wa pearlite.Ifite imashini nziza, irwanya ruswa nziza, ihindagurika ryiza, ingaruka nziza yo gufunga, kuyishyiraho byoroshye, kandi ikoreshwa cyane cyane mugutanga amazi, kohereza gaze, kohereza peteroli, nibindi mubigo bya komini, inganda nubucukuzi.

Umubare munini wa spherical grafite ukwirakwizwa kuri materique ya ferrite na pearlite.Ukurikije diameter zitandukanye nominal nibisabwa kugirango urambe, igipimo cya ferrite na pearlite muburyo bwa matrix kiratandukanye.Umubare wa pearlite ufite diameter ntoya muri rusange ntabwo urenga 20%, naho iya diameter nini igenzurwa hafi 25%.

Pimikorere ya dUmuyoboro w'icyuma

Umuyoboro w'icyuma ni ubwoko bw'icyuma, kikaba ari icyuma, karubone na silikoni.Graphite muri spheroidal grafite yamashanyarazi ibaho muburyo bwa spheroidal grafite.Mubisanzwe, ingano ya grafite ni 6-7, naho urwego rwa spheroidisation ya pipe ya pisine irasabwa kugenzurwa kugeza kuri 1-3 (igipimo cya spheroidisation ≥ 80%) muburyo bwiza.Kubwibyo, imiterere yubukanishi bwibikoresho ubwabyo byarushijeho kunozwa, hamwe na kamere yicyuma nibiranga ibyuma.Imiterere ya metallografiya yumuyoboro wicyuma ushyizwe hamwe ni ferrite wongeyeho umubare muto wa pearlite, kandi imiterere yubukanishi nibyiza.

Umuyoboro wibyuma byitwa cyane cyane centrifugal ductile Iron pipe.Ifite imiterere yicyuma, imikorere yicyuma, irwanya ruswa nziza, ihindagurika ryiza, ingaruka nziza yo gufunga, kuyishyiraho byoroshye, kandi ikoreshwa cyane cyane mugutanga amazi, kohereza gaze, kohereza peteroli, nibindi mubigo bya komini, inganda nubucukuzi.Nibwo buryo bwambere bwo guhitamo imiyoboro itanga amazi hamwe nigiciro kinini.Ugereranije numuyoboro wa PE, igihe cyo kwishyiriraho umuyoboro wicyuma cyoroshye kiroroshye kandi cyihuta kuruta umuyoboro wa PE, kandi umuvuduko wimbere ninyuma nibyiza nyuma yo kwishyiriraho;Urebye uburyo bwo guhumeka neza no kurwanya ruswa, ubwinshi bwumuyaga wa spheroidal grafite umuyoboro nyuma yo kwishyiriraho ni byiza, kandi kurwanya ruswa bishobora no kunozwa nuburyo butandukanye bwo kurwanya ruswa;Duhereye ku mikorere ya hydraulic, kubera ko ibisobanuro byerekana umuyoboro w'icyuma uhindagurika muri rusange bivuga umurambararo w'imbere, ibisobanuro by'umuyoboro wa PE muri rusange bivuga umurambararo wo hanze, kubera ko mu bihe bimwe bisobanutse, umuyoboro w'icyuma uhindagurika ushobora kugera ku mazi menshi;Duhereye ku buryo bwuzuye bwo kwishyiriraho no kubungabunga, umuyoboro w'icyuma uhindagurika ufite imikorere myiza.Urukuta rw'imbere rwatewe na zinc, sima ya minisiteri yo kurwanya ruswa, n'ibindi.

Mumutungo wa echanical ya dUmuyoboro w'icyuma

Imbaraga ntarengwa: 420 / MPa

Imbaraga nkeya: 300 / MPa, kuramba byibuze 7%

Ibipimo: GB / T13295-2013, ISO2531-2009

Diameter: DN80-DN2600

Ibyifuzo byo guhitamo ya dUmuyoboro w'icyuma

1. Guhitamo imiyoboro yicyuma ihindagurika igomba gushingira kumiterere yihariye yahantu hashyizwe, kandi hazatoranywa imiterere yimiyoboro igororotse hamwe nibikoresho.

2. Impeta ya reberi ikozwe muri NBR, SBR, EPDM nibindi bikoresho.

3. Guhitamo igifuniko: hitamo igifuniko gikwiye ukurikije imiterere yimbere ninyuma mugihe cyo gukoresha.Ipfunyika yimbere iriho ni epoxy resin, polyurethane yimbere ninyuma, gutwikira firime PE nibindi bicuruzwa bishya byumuyoboro wibyuma, kandi imikorere yayo igomba kumvikana muburyo burambuye muguhitamo.

Ibyiza n'ibibi ya dUmuyoboro w'icyuma

Advantage

Imiyoboro y'icyuma ikoreshwa mu miyoboro iciriritse kandi ntoya (muri rusange ikoreshwa munsi ya 6MPa).Imiyoboro yicyuma ifite imikorere yizewe kandi yizewe, igipimo cyangiritse gito, kubaka kandi byihuse no kuyitaho, hamwe no kurwanya ruswa.Umuyoboro mushya wa "Yandun" urashobora gukoreshwa mubwubatsi butagira umwobo kandi bigakoreshwa cyane mukubaka imiyoboro hakurya yinzuzi, imihanda ninyubako.Umuyoboro wa "Saizin" ukoresha uburyo bwihariye bwa zinc aluminium alloy yo gutera hanze kugirango utezimbere kwangirika kwumuyoboro inshuro nyinshi, kandi ukoreshwa cyane mukubaka ubutaka bwangirika cyane.

Disadvantage

Mubisanzwe, ntabwo ikoreshwa mumiyoboro yumuvuduko mwinshi (hejuru ya 6MPa).Kuberako umubiri wumuyoboro uremereye cyane, imashini zigomba gukoreshwa mugihe cyo kwishyiriraho.Mugihe amazi yamenetse nyuma yikizamini cyumuvuduko, imiyoboro yose igomba gucukurwa, imiyoboro igomba kuzamurwa mukurebure aho ishobora gushyirwa mumashanyarazi, hanyuma hagashyirwaho clamp kugirango hirindwe amazi.

Twe JINBAICHENG isumwe mubakora ibicuruzwa bizwi cyane, byohereza ibicuruzwa hanze, abanyamigabane, abafite imigabane nuwabitanzeumuyoboro w'icyuma.Dufite abakiriya baturutse muri Mexico, Turukiya, Pakisitani, Oman, Isiraheli, Misiri, Abarabu, Vietnam, Miyanimari, Ikidage, n'ibindi.
