Kuzivisa K7 Ductile Iron Pipe

Chii chinonzi pombi yesimbi yeK7 grade ductile? Uye inobatsira sei mapurojekiti einjiniya uku tichiona kuchengetedzeka? Nhasi, tichaongorora nyaya iyi totsanangura kuti nei mabrandi ehunyanzvi akaita seDINSEN ari kuva zviyero zvemhando yepamusoro muindasitiri.

Kurongwa kwe "K" series yemapombi esimbi ane ductile. Mu standard yepasi rose ISO 2531 uye standard yenyika GB/T 13295,mapaipi esimbi ane ductilezvakakamurwa kuita K9, K8, K7, K12, nezvimwewo, zvichienderana nekukora kwemadziro. Pano, "K" inomiririra coefficient yekukora kwemadziro epombi; nhamba inotevera K yakakura, ndiko kukura kwemadziro epombi.

Kwenguva yakareba, mapaipi esimbi emhando yeK9 grade ductile ave ari iwo musimboti wemapaipi ekufambisa mvura nekuda kwekusasimba kwawo kwakanyanya. Zvisinei, mukuita mapurojekiti makuru ekutsigira enyika akadai seSouth-to-North Water Diversion Project, mainjiniya vakaona kuti pamapaipi akawanda egiravhiti anoshanda pakumanikidzwa kweinenge 1.0 MPa kana kudzika, kusasimba kwesimba remapaipi emhando yeK9 chaizvoizvo "kwakadarika mwero."Mapaipi esimbi eK7 ductilezvave zvichishandiswa zvakanyanya munyaya iyi. Kana tichienzanisa neK9, K7 ine ukobvu hwakatetepa hwemadziro, asi ine mwero wepamusoro muhunhu hwemakanika: simba rekudhonza ≥420MPa, simba rekupa ≥300MPa, uye kuomarara ≤230HBW. Izvi zvinoreva kuti K7 yakabudirira kuwana magadzirirwo ezvinhu zvakanaka uku ichisangana nezvinodiwa zvekumanikidzwa kwemukati uye mutoro wekunze wemamiriro ekushanda chaiwo.

Kusarudza mapaipi esimbi eDINSEN semutengesi wemapaipi eK7 zvinoreva kusarudza vimbiso nhatu:

1. Kudzora ukobvu hwemadziro nemazvo uye hunhu hwemakanika hwakanaka;
2. Sisitimu yakakwana yekudzivirira ngura, inowedzera hupenyu hwebasa;
3. Tekinoroji yekushandiswa kweinterface inochinjika uye kugona kwayo kuchinjika pakuvaka.

Sei uchifanira kusarudza K7?

• Mari yezvinhu inoderedzwa. Kana tichienzanisa neK9, K7 ine rusvingo rwakatetepa, zvichiita kuti huremu huremu huremu pahurefu hwepombi imwe chete, zvichideredza zvakananga mari yezvinhu zvisina kugadzirwa.
• Mari yekufambisa nekuisa zvinhu yaderedzwawo: huremu hwakareruka hunoreva kuwedzera kwehuwandu hwekutakura parwendo rumwe chete, uye kusimudza nekubata zvinhu panzvimbo yacho kuri nyore, zvichiita kuti mari yekushanda kwevashandi nemichina ideredzwe.
• Kuchengetedza zviwanikwa kunowanikwawo: kubva pamaonero makuru, kusarudzwa kwakanaka kwemapombi eK7 kunoderedza kushandiswa kwezviwanikwa zvakaita sesimbi necoke, zvichienderana negwara renyika rekugadzira zvinhu zvekuvaka zvakasvibira uye zvine kabhoni shoma.

KusarudzaMapaipi esimbi eDINSEN ane ductilehakusi kungosarudza pombi chete, asiwo kusarudza mubatsiri wehunyanzvi achibatanidza mazano ehunyanzvi, kupa zvigadzirwa, uye sevhisi yekutengeswa mushure mekutengesa.
