Mukuvaka mvura nemidziyo yekubvisa mvura, uye muinjiniya yemaguta, mapaipi esimbi anonyanya kufarirwa nekuda kwekugara kwawo kwenguva refu, kuramba ngura, uye kuderedza ruzha. Zvisinei, kana vakatarisana nezvinodiwa zviviri zveEurope, EN545 neEN877, mainjiniya mazhinji, vashandi vekutenga, nevagadziri vanogona kuvhiringidzika: Ose anoita se "mapaipi esimbi," saka musiyano wacho chii chaizvo?
Kutaura zvazviri, pane musiyano mukuru pakati pezviviri izvi, uye sarudzo pakati pazvo inokanganisa zvakananga kuchengetedzeka, kuvimbika, uye kushanda zvakanaka kwepurojekiti. Zvichitaurwa zviri nyore, EN545 ndiyo "yakasimba" yemapaipi emvura ane simba, nepo EN877 iri "nyanzvi" yemapaipi emvura asina simba. Kunzwisisa kusiyana kwawo ndiyo nhanho yekutanga pakusarudza zvinhu zvakakodzera.
- EN877 pombi yesimbi yakakandwa(simbi yakakandwa yegrey): Iyi isimbi yakakandwa yechinyakare. Kabhoni yayo inowanikwa muchimiro chegrafiti yakakandwa. Aya magrafiti akakandwa anoita se "maburi echisikigo" asingaverengeki akaiswa mu matrix yesimbi, zvichikanganisa zvakanyanya kuenderera mberi kwe matrix. Kana ikaiswa pakumanikidzwa kana kukanganiswa, kushushikana kunowanikwa pamigumo yemagrafiti aya, zvichiita kuti zvinhu zvive nyore kuputsika. Nekuda kweizvozvo, pombi yesimbi yakakandwa yeEN877 inozivikanwa nekuoma kwayo kwakanyanya uye simba rinogamuchirika rekumanikidza, asiwo nekuoma kwayo kwakanyanya uye kuputsika.
- EN545 pombi yesimbi ine ductile: Izvi zvinokonzerwa netekinoroji yemazuva ano yesimbi. Munguva yekunyungudutsa, zvinhu zvinonyungudutsa (zvakaita semagnesium nezvinhu zvisingawanzoitiki zvepasi) zvinowedzerwa kusimbi yakanyungudutswa kuti zvishandure graphite kubva paflakes kuita maumbirwo edenderedzwa. Kuchinja uku kunochinja-chinja: graphite yakatenderera inoderedza kukanganisa kwesimbi, ichibvisa nzvimbo dzakaoma dzekumanikidzwa. Izvi zvinobvumira simbi kuti ione simba rayo uye ductility yayo zvizere. Ductile iron saka inosanganisa simba resimbi (simba rakasimba rekudhonza) nehunhu hwakanaka hwesimbi yakakandwa.
| Ductile Iron Pipe | Pombi yeSML | |
| Zvivakwa zveMichina | Simba guru, kusimba kwakanyanya, kuramba kukanganiswa | Kuputsika kwakanyanya uye kuramba kusingakuvadzi |
| Simba reKusimba | ≥ 420 MPa | ≈ 150 MPa |

Ungasarudza sei pombi yesimbi yakakandwa neductile chaiyo?
Kana sisitimu yako ichida kutakura mvura ine simba uye ichida kuchengetedzeka uye kuvimbika kwemapaipi zvakanyanya, EN545 ductile iron pipe ndiyo sarudzo inosarudzwa.
- Migero yemvura yemuguta: Mapaipi aya anotakura huremu hwe "tsinga dzeropa" dzeguta, achitakura simba rekumanikidzwa kwemvura mukati uye ivhu rekunze.
- Mapaipi etsvina ane simba guru uye emumaindasitiri: Aya anoshandiswa pamapaipi anoburitsa simba mushure mekupomba uye pakufambisa zvinhu mumaindasitiri.
- Munzvimbo dzinoda kudzivirirwa nekudengenyeka kwenyika: Majoini adzo anochinjika anodzivirira kufamba kunokonzerwa nemafungu ekudengenyeka kwenyika, zvichidzivirira kuparara kwepombi.
- Munzvimbo dzine nheyo dzakaoma: Dzinogona kugamuchira nzvimbo dzisina kuenzana.
Kana sisitimu yako isiri yekumanikidzwa, ichishandisa simba rinokwevera pasi rine zvinodiwa zvekudzivirira moto uye kushanda pasina ruzha, pombi yesimbi yeEN877 isarudzo inodhura zvishoma uye inoshanda.
- Masisitimu emvura inoyerera mumba: Aya ndiwo mhinduro yakakwana yezvinhu zvese kubva mudzimba dzekugezera nemakicheni kusvika kumadhiraivha anosimudza mvura.
- Masisitimu emvura anodonhedza denga: Aya anounganidza uye anoburitsa mvura yemvura kubva mukati mechivako. Mapaipi emvura yemuguta asingashandise simba: Anoshandiswa kuunganidza uye kutakura mvura yemumba ine tsvina nemvura yemvura inonaya.
- Kune nzvimbo dzinoda kuvharwa kweruzha rwakanyanya: Huremu hwemapaipi esimbi yakaumbwa uye magadzirirwo ekristaro anopa kuvharwa kweruzha kwakanakisa, kuri nani kupfuura mapaipi epurasitiki.
