Ductile Iron Pipe ID here kana kuti OD?

Mumapurojekiti ekugadzirisa mvura yemumaguta, kudhonza mvura, uye kuvharira mapaipi asina tambo, mapaipi esimbi ane ductile, ane hunhu hwawo hwakanaka hwemakanika uye anodzivirira ngura, ave imwe nzira yakanaka pane mapaipi esimbi egrey nemapaipi esimbi. Vashandi vazhinji vanotenga, pavanoongorora runyorwa, vanotanga vatarisa dhayamita yezita (DN). Zvisinei, mukuvaka chaiko, OD inosarudza hupamhi hwekuchera mugero, dhayamita yemukati inokanganisa kugona kwemvura, uye ukobvu hwemadziro hunoenderana zvakananga nehupenyu hwepombi uye chiyero chekumanikidzwa.

Nhasi, tichatarisa papombi yesimbi yeK9 grade ductile inoshandiswa zvakanyanya, tichiongorora zvakadzama pfungwa yechigadzirwa cheID neOD nehukobvu hwemadziro kuti tikubatsire kuona kuti zvinhu zviri kubva kupi.

1. Fomura Yekuverenga Ukobvu Hwemadziro

Giredhi reK9 ndiro rinonyanya kutsanangurwa pakukora kwemadziro muinjiniya yemunicipal engineering. Ukobvu hwemadziro hwakajairwa hunoverengerwa uchishandisa fomura inotevera:

T=K×(0.5+0.001DN)

Kana K=9, inenge iri pombi yesimbi ine ductile yeK9. Kune dhayamita diki (DN100-DN200), muganho weukobvu hwemadziro hunodiwawo kuti pave nechokwadi chekuti pombi yacho yakasimba zvakakwana panguva yekubata nekuvaka.

2. ID ndiyo kukosha kwekuverenga kwedzidziso (OD – 2 × ukobvu hwemadziro), uye kukosha kwayo kunogona kusiyana zvishoma nekuda kweukobvu hwemukati mesimbi yesimbi yesimbi.

Kunyatsojeka kweID neOD yemapombi esimbi ane ductile kunosarudza zvakananga mashandiro ekuvharaMajoini emhando yeT kana K.

Madhayamita emukati nekunze uye ukobvu hwemadziro emapombi esimbi ane ductile hazvisi zvinhu zvinotonhora chete, asiwo zviratidzo zvakakosha zvemhando yepombi. Kubva pakupinza simbi kubva pakukanda kusvika pakugadzika simende, mirimita yega yega yekunyatsojeka inokanganisa mashandiro akachengeteka enetwork yepombi kwemazana emakore.
