1. Pfungwa dzakasiyana
Pombi yesimbi yakagadzirwa nemuchina ipombi yesimbi inokandwa ine nzira inochinjika yekubuda kwemvura inogadzirwa ne centrifugal casting process. Iyo interface inowanzo kuve mhando ye clamp yemhando ye W kana mhando ye A-type flange socket.
Mapaipi esimbi anoshandiswa mudura resimbi anoreva mapaipi anogadzirwa nesimbi inokurumidza kushandisa muchina wesimbi unoshandiswa mudura resimbi mushure mekuwedzera chinhu chinonyungudutsa simbi yakanyungudutswa pamusoro penhamba 18. Anonzi mapaipi esimbi anoshandiswa mudura resimbi, mapaipi esimbi anoshandiswa mudura resimbi uye mapaipi anoshandiswa mudura resimbi. Anonyanya kushandiswa kutakura mvura yepombi, chinhu chakanakira mapaipi emvura yepombi.
2. Kushanda kwakasiyana
Ductile iron pipe rudzi rwesimbi yakakandwa, alloy yesimbi, kabhoni nesilicon. Graphite musimbi yakakandwa inowanikwa muchimiro chespheroids. Kazhinji, saizi yegraphite igiredhi 6-7. Hunhu hunoda kuti spheroidization grade yepipe yakakandwa idzorwe kusvika kugiredhi 1-3, saka hunhu hwemuchina hwechinhu chacho hunovandudzwa zviri nani. Ine hunhu hwesimbi uye hunhu hwesimbi. Chimiro chemetallographic chepipe yesimbi yakakandwa iferrite pamwe nehuwandu hushoma hwepearlite, uye hunhu hwayo hwemuchina hwakanaka.
Nguva yebasa remapaipi esimbi akagadzirwa nemuchina inodarika nguva inotarisirwa yekuvaka. Inodzivirira kudengenyeka kwenyika zvakanyanya uye inogona kushandiswa kudzivirira kudengenyeka kwezvivako zvirefu. Inoshandisa ma flange glands nema rabha kana ma rabha ane jira rakarukwa uye ma clamps esimbi isina tsvina kuti ibatanidzwe zviri nyore. Ine chisimbiso chakanaka uye inobvumira Kutenderera mukati memadhigirii gumi nemashanu pasina kubuda mvura.
Kushandiswa kwesimbi kugadzira centrifugal casting. Pombi yesimbi yakakandwa ine ukobvu hwakafanana pamadziro, chimiro chakabatana, nzvimbo yakatsetseka, uye isina zvikanganiso zvekukanda zvakaita semablister uye slag inclusions. Rabha inovhara ruzha uye haitsiviwe nemapombi akanyarara, zvichiita kuti pave nenzvimbo yekugara yakanakisisa.
3. Mashandisirwo akasiyana
Mapaipi esimbi akakodzera kuvaka nzira dzekubvisa mvura, nzira dzetsvina, mainjiniya ekuvaka, nzira dzekubvisa mvura mumigwagwa, nzira dzemvura dzakaora dzemaindasitiri, uye nzira dzekudiridza zvekurima; mapaipi esimbi akakodzera nzvimbo yakakura yekuwedzera axial uye kudzika kwe contraction uye deformation yemapaipi padivi; mapaipi esimbi akakodzera kudengenyeka kwenyika kune simba re9 degrees. Shandisa munzvimbo dzinotevera.
Pombi yesimbi inonzi ductile iron inonyanya kunzi centrifugal ductile iron pipe. Ine musimboti wesimbi uye mashandiro ayo. Ine mashandiro ayo akanaka ekudzivirira ngura, kugona kwayo kuchinjika, kushanda kwayo zvakanaka, uye iri nyore kuisa. Inonyanya kushandiswa pakupa mvura, kutapurirana gasi, uye kutakura mumabhizinesi emakanzuru, maindasitiri uye emigodhi, mafuta nezvimwewo. Ipombi yemvura uye ine mashandiro ayo anodhura zvakanyanya.
