1. Nhanganyaya
Mumunda weinjiniya yemazuva ano, ductile iron yave chinhu chinofarirwa kumapurojekiti mazhinji ane mabhenefiti ayo akasiyana ekuita. Pakati peakawanda ductile iron zvigadzirwa,dinsen ductile iron mapaipivakunda nyasha uye kucherechedzwa kwevatengi kubva pasi rese nemhando yavo yepamusoro uye inoshanda yekugadzira kutenderera. Ichi chinyorwa chichaongorora nzvimbo dzekushandisa uye nzira dzekuisa ductile iron zvakadzama, uye panguva imwechete inoratidza kunaka kwemhando ye dinsen ductile iron mapaipi.
2. Hunhu hwe ductile iron
Ductile iron isimbi yakakwirira-yakasimba. Kuburikidza nechirongwa chekurapa chakakosha, graphite inogoverwa muchimiro chedenderedzwa musimbi matrix. Ichi chimiro chinopa ductile iron akawanda akanakisa zvivakwa:
Simba repamusoro: Ductile iron ine simba rakawanda rekusimba uye goho simba, uye inogona kumirisana nekumanikidza kukuru uye mutoro.
Kusimba kwakanaka: Kuenzaniswa nesimbi yakajairwa, ductile iron ine kusimba kuri nani uye haitani kutsemuka.
Corrosion resistance: Iine kumira zvakanaka kune dzakasiyana siyana zvinosvibisa midhiya uye inorebesa hupenyu hwayo hwesevhisi.
Zvakanaka machinability: Inogona kugadzirwa kuita zvigadzirwa zvemhando dzakasiyana uye saizi kuburikidza nenzira dzakasiyana dzekugadzirisa.
3. Kushandiswa kwe ductile iron
3.1Mvura yemvura uye nzvimbo yekudhonza mvura
Ductile iron mapaipi akashandiswa zvakanyanya mukupa mvura uye mapurojekiti ekudhonza. Kupokana kwayo necorrosion, kusimba kwepamusoro uye kuiswa chisimbiso kwakanaka kunovimbisa kuchengetedzeka uye kuvimbika kwekupihwa kwemvura uye kudhiraivha. Dinsen ductile iron pombi yave sarudzo yekutanga kune akawanda emadhorobha emvura uye madhiraini masisitimu ane emhando yepamusoro.
Muzvigadziriso zvekuchenesa tsvina, mapaipi e ductile iron anoshandiswawo kutakura tsvina uye sludge, uye kushorwa kwavo kwekuora kunogona kunyatso kurwisa kukukurwa kwemakemikari mutsvina.
3.2 Municipal engineering
Mukugadzirwa kwemigwagwa yemumadhorobha uye mabhiriji, ductile iron manhole anovhara uye magirasi emvura inonaya anoshandiswa zvakanyanya. Ivo vane hunhu hwekusimba kwepamusoro, corrosion resistance uye anti-slip, uye vanokwanisa kushingirira kurema kwemota nevanofamba netsoka.
Ductile iron inoshandiswawo kugadzira zvivakwa zvemanisipala zvakaita semapango emwenje yemumugwagwa nemapango ezviratidzo zvemumigwagwa. Kuita kwayo kwakanaka uye kuramba kwemamiriro ekunze kunoita kuti iite zvakanaka munzvimbo dzekunze.
3.3 Indasitiri munda
Munzvimbo dzemaindasitiri senge peturu, indasitiri yemakemikari, uye simba remagetsi, pombi dzesimbi dze ductile dzinoshandiswa kutakura midhiya yakasiyana-siyana yakadai semafuta asina kuchena, gasi rechisikigo, chiutsi, etc. Kuramba kwayo kwekuora uye simba rakakwirira rinogona kusangana nezvinodiwa zvakasimba zvekugadzirwa kwemaindasitiri.
Ductile iron inoshandiswawo kugadzira zvikamu zvema mechanical, zvakadai semagiya, crankshafts, matanda ekubatanidza, nezvimwewo. Yayo yakanaka mechanical properties uye machinability inoita kuti zvikamu izvi zviite basa rinokosha mumichina yemagetsi.
4. Zvakanakira dinsen ductile iron mapaipi
4.1 Hunhu hwepamusoro
Dinsen ductile iron mapaipi anotora tekinoroji yekugadzira uye yakasimba yemhando yekudzora system kuti ive nechokwadi chemhando yepamusoro yechigadzirwa. Zvinhu zvaro zvakangofanana, simba rakawanda, kunaka kwekusagadzikana kwecorrosion, uye inogona kusangana nezvinodiwa zvemapurojekiti akasiyana.
Iyo kambani ine hunyanzvi hwekuyedza michina uye matekinoroji ekuita bvunzo dzakasimba pane yega yega ductile iron pombi kuti ive nechokwadi chekuti chigadzirwa chinosangana nemazinga epasi rose uye zvinodiwa nevatengi.
4.2 Kutenderera kwekugadzira kwakanaka
Kambani yeDinsen ine michina yekugadzira yepamusoro uye inoshanda yekugadzira manejimendi system, iyo inogona kupfupisa kutenderera kwekugadzira uku uchisimbisa mhando. Izvi zvinoita kuti vatengi vawane zvigadzirwa zvinodiwa munguva uye kugadzirisa kufambira mberi kweprojekiti.
Iyo kambani inopawo zvakagadziridzwa masevhisi, inogadzira ductile iron mapaipi eakasiyana maratidziro uye modhi zvinoenderana nezvinodiwa chaizvo nevatengi kuti vasangane nezvinodiwa zvevatengi.
4.3 Yakakwana mushure mekutengesa sevhisi
Kambani yeDinsen inoteerera kune basa revatengi uye inopa yakakwana mushure mekutengesa sevhisi. Iyo kambani ine nyanzvi dzematekinoroji dzinogona kupa vatengi nhungamiro yekuisa uye rutsigiro rwehunyanzvi kuti ive nechokwadi chekumisikidzwa uye kushandiswa kwepombi dzesimbi dze ductile.
Munguva yekushandiswa kwechigadzirwa, kambani inogara ichishanyira vatengi kuti vanzwisise kushandiswa kwechigadzirwa uye kugadzirisa matambudziko anosangana nevatengi nenguva.
5. Kuisa nzira ye ductile iron pipes
Kugadzirira basa
Usati waisa ductile iron pombi, nzvimbo yekuvaka inoda kucheneswa kuti ive nechokwadi chekuti nzvimbo yacho yakati sandara uye haina zvipingamupinyi.
Zvinoenderana nezvinodiwa zvekugadzira, sarudza nzira yekuisa uye kutsetseka kwepombi, uye kuyera uye kuisa mitsara.
Gadzirira maturusi uye zvinhu zvinodiwa pakugadzika, senge cranes, magetsi welders, rubber sealing rings, nezvimwe.
Pipeline connection
Pane nzira mbiri huru dzekubatanidza ductile iron mapaipi: socket connection uye flange connection. Socket connection kuisa socket yepombi musocket yeimwe pombi, wobva waisunga nerabha sealing ring. Kubatana kweFlange kubatanidza mapaipi maviri pamwechete kuburikidza neflange, wobva waasimbisa nemabhaudhi.
Paunenge uchibatanidza mapaipi, zvinodikanwa kuve nechokwadi kuti mitsetse yepakati yepombi yakaenzana, mapeji ari pakati pezvigadziko uye zvigadziko ari yunifomu, uye zvindori zvekuisa rubber zvakaiswa nenzira kwayo.
Kuiswa kwepombi
Pakuisa pombi, crane inodiwa kuisa pombi zvishoma nezvishoma mugoronga kudzivirira kubonderana pakati pepombi nemadziro emugero.
Mushure mekunge pombi yaiswa, pombi inoda kugadziridzwa kuti ive nechokwadi chekuti materu nepakati mutsara wepombi zvinosangana nezvinodiwa zvekugadzira.
Zvadaro, pombi inogadziriswa kudzivirira kutamiswa panguva yekushandiswa.
Pipeline pressure test
Mushure mekunge pombi yaiswa, pombi inoda kuyedzwa kuedzwa kuti itarise kusimba uye kusimba kwepombi. Munguva yekuedzwa kwekumanikidza, pombi inoda kuzadzwa nemvura uye ipapo kudzvanywa kunowedzera zvishoma nezvishoma kusvika yasvika 1.5 nguva yedhizaini yekumanikidza.
Munguva yekuedzwa kwekumanikidza, pombi inoda kuongororwa kuti ione kana paine kuvuza uye deformation. Kana matambudziko
6. Mhedziso
Seyepamusoro-inoshanda zvinhu, ductile iron inoshandiswa zvakanyanya munzvimbo dzakasiyana siyana. Dinsen ductile iron mapaipi akahwina kufarirwa uye kucherechedzwa kwevatengi kubva kumativi ese epasi nemhando yavo yepamusoro, inoshanda kutenderera kutenderera uye yakakwana mushure mekutengesa sevhisi. Mukuvandudza mune ramangwana, ductile iron icharamba ichitamba zvakanakira uye nekupa mhinduro dzakavimbika dzekuvaka engineering. Dinsen icharamba ichigadzira uye kufambira mberi kupa vatengi zvigadzirwa zviri nani uye masevhisi.
