Kanda simbi pombi

Pombi yesimbi (cast iron pipe) zvinoreva pombi inokandwa nesimbi.Cast iron pombi inoshandiswa kugovera mvura, kudhiraivha uye gasi kutapurirana mapaipi, kusanganisira akakanda simbi yakatwasuka pombi uye pombi fittings.Simba rekushanda rakaderera.Zvinoenderana neakasiyana nzira dzekukandira, inokamurwa kuva inoenderera yakakandwa simbi pombi uye centrifugal cast iron pombi, pakati peiyo centrifugal cast iron pombi inokamurwa kuita jecha mold uye simbi mold.Zvinoenderana neyakasiyana zvinhu, yakakamurwa kuita grey cast iron pombi uye ductile iron pombi.Zvinoenderana neakasiyana mafomu mafomu, yakakamurwa kuita inochinjika interface, flange interface, yega-anchor interface, yakasimba interface, nezvimwe.

Chinokosha chepombi yesimbi inonzi ductile iron pipe, inodaidzwa kuti iyi nokuti ine chimiro chesimbi uye kushanda kwesimbi.Iyo graphite mu ductile iron pombi iripo mune spherical fomu, uye saizi yegraphite kazhinji ndeye 6-7.Hunhu hunoda kuti spheroidization level yecast iron pombi idzorwe kusvika padanho 1-3, uye spheroidization rate iri ≥80%, saka michina yemidziyo pachayo inovandudzwa zvakanaka, nehunhu hwesimbi uye kushanda kwesimbi. .Mushure mekuvhara, iyo metallographic chimiro che ductile iron pombi ndeye ferrite pamwe nediki diki pearlite, uye michina yemagetsi yakanaka, saka inonziwo cast iron pombi.
