1. Mafungiro akasiyana
Muchina-wakagadzirwa cast iron pombi ipombi yakakandwa yesimbi ine inoshanduka interface drainage inogadzirwa ne centrifugal casting process.Iyo interface inowanzoita W-mhando yekusungirira mhando kana A-mhando flange socket mhando.
Ductile iron pipes zvinoreva mapaipi anokandwa nehigh-speed centrifugal casting achishandisa muchina wesimbi wecentrifugal ductile mushure mekuwedzera nodulizing agent kukanda simbi yakanyungudutswa pamusoro peN. .Inonyanya kushandiswa kutakura mvura yepombi, chinhu chakanakira pombi yemvura pombi.
2. Kuita kwakasiyana
Ductile iron pipe imhando yesimbi yakakandwa, alloy yesimbi, kabhoni uye silicon.Graphite mu ductile iron iripo muchimiro che spheroids.Kazhinji, saizi yegraphite igiredhi 6-7.Hunhu hunoda kuti giredhi re spheroidization yepombi yakakandwa idzorerwe kusvika kugiredhi 1-3, saka michina yemidziyo yacho pachayo inovandudzwa.Iyo ine essence yesimbi uye zvinhu zvesimbi.Iyo metallographic chimiro cheiyo annealed ductile iron pombi ndeye ferrite pamwe nediki diki pearlite, uye ayo emakanika maitiro akanaka.
Hupenyu hwesevhisi yemuchina wakagadzirwa nesimbi mapaipi anodarika hupenyu hunotarisirwa hwechivako.Iyo ine yakanakisa kudzivirira kwekudengenyeka uye inogona kushandiswa kudzivirira kudengenyeka kwezvivakwa zvepamusoro-soro.Inoshandisa flange glands uye mhete dzerabha kana mhete dzerabha dzine mitsetse uye masimbi esimbi asina tsvina kuti abatanidzwe zviri nyore.Iyo ine chisimbiso chakanaka uye inobvumira Swings mukati megumi nemashanu madhigirii pasina kudonha.
Metal mold centrifugal casting inogamuchirwa.Iyo pombi yesimbi yakakandwa ine yunifomu yemadziro ukobvu, compact chimiro, yakatsetseka pamusoro, uye isina kukanganisa kukanda senge blisters uye slag inclusions.Iyo rabha interface inodzvinyirira ruzha uye haidzoreki kune iyo yakanyarara pombi, ichigadzira yakanakisa nharaunda yekugara.
3. Kushandiswa kwakasiyana
Pombi dzesimbi dzakakandwa dzakakodzerwa nekuvaka dhiraivha, tsvina yesuweji, engineering yevagari vemo, mugwagwa wemvura, tsvina yemaindasitiri, uye pombi dzekudiridza dzekurima;pombi dzesimbi dzakakandwa dzinogona kuve dzakakodzera kukura kweaxial yakakura uye contraction displacement uye lateral deflection deformation yemapaipi;pombi dzesimbi dzakakandwa dzakakodzerwa nekudengenyeka kwenyika nekusimba kwe9 madhigirii Shandisa munzvimbo dzinotevera.
Ductile iron pombi inonyanya kunzi centrifugal ductile iron pipe.Iyo ine hunhu hwesimbi uye kushanda kwesimbi.Iyo ine yakanakisa anti-corrosion performance, yakanaka ductility, yakanaka yekuisa chisimbiso maitiro, uye iri nyore kuisa.Inonyanya kushandiswa kugovera mvura, kutapurirana gasi, uye kufambisa mumadhorobha, maindasitiri nemabhizinesi emigodhi.mafuta etc. Ipombi yekupa mvura uye ine mari yakawanda yekuita.
