Pakati pa zomangamanga ndi njira zoyendera madzi, gawo lililonse la mapaipi achitsulo chosungunuka silimangokhala ndi madzi ndi gasi, komanso limakhudza chitukuko cha mizinda ndi ubwino wa nzika. Pano, ubwino si nkhani chabe; ndi chikhulupiriro ndi kudzipereka komwe kumalukidwa mu inchi iliyonse yachitsulo ndikuphatikizidwa mu njira iliyonse.DINSENPodziwa bwino udindo wofunikawu, imayesetsa kutsatira bwino kwambiri muyezo wapadziko lonse wa ISO2531, kusonyeza mgwirizano wolimba wa kuwunika khalidwe la kampani.Mapaipi achitsulo a ISO2531 opangidwa ndi ductile.
Muyezowu umatchula zofunikira zaukadaulo, njira zoyesera ndi kuwongolera khalidwe la mapaipi achitsulo opangidwa ndi ductile, zolumikizira, zowonjezera ndi malo ake olumikizirana omwe amagwiritsidwa ntchito ponyamula madzi (monga madzi akumwa, madzi othirira, ndi zina zotero).
1. Chitoliro chachitsulo chosungunukaDE
M'mimba mwake wakunja kwa soketi mutha kudziwa poyesa kuzungulira ndi tepi yoyezera. Kapenanso, miyeso iwiri yokhala ndi caliper iyenera kuchitidwa pamalo opingasa kudutsa gawo lopingasa.Fomula ya ovality ndi iyi: Ovality = (A1-A2)/(A1+A2).
2.Chitoliro chachitsulo chosungunukaID
Chitoliro chamkati cha chitoliro chachitsulo chopangidwa ndi centrifugally chili pafupifupi chofanana ndi chitoliro chake chapadera, DN value, mu mamilimita.
3. Chitoliro chachitsulo chosungunukaKukhuthala kwa Khoma
Gwiritsani ntchito choyezera makulidwe a ultrasonic ndi cholumikizira china kuti mugwirizane ndi malo omwe mukuyezera. Kulondola kwa chida ndi 0.1mm. Malo oyezera ndi osachepera malo awiri otsutsana kumapeto kwa chinthucho. Zotsatira za muyeso zikugwirizana ndi tebulo lotsatirali:
4. Utali wa Chitoliro cha Ductile Iron
5. Kuzungulira kwa ellipticity
Kuzungulira kwa gawo la mtanda wa chitoliro chopangidwa ndi chitsulo.
Ovality = 100 x (A1-A2) / (A1+A2)
A1: kupitirira apo A2: Kakang'ono
6. Kuwongoka
Mapaipi opangidwa ndi chitsulo ayenera kukhala owongoka, ndipo kusiyana kwakukulu kosapitirira 0.125% ya kutalika koyenera (6000 x 0.125% = 7.5mm).Ngati chitolirocho chili chopanda chopinga, kuyang'ana kowoneka bwino kuyenera kugwiritsidwa ntchito kuti chikhale chowongoka. Ngati mukukayikira, njira yotsatirayi iyenera kugwiritsidwa ntchito.Pukutani chitolirocho mozungulira pa ma stand awiri kapena ma rollers kuti muwone ngati chili chowongoka. Mipata pakati pa ma stand/rollers iyenera kukhala osachepera 2/3 ya kutalika kwa chitolirocho. Malo oti mupatuke kwambiri kuchokera pa kuongoka ayenera kudziwika, ndipo kupotokako sikuyenera kupitirira malire a 7.5mm.
7. Kapangidwe ka mphamvu yokoka
Zofunikira ndi izi:
Zofunikira pa kulephera: Tengani mipiringidzo iwiri yoyesera kuchokera ku mphete imodzi ya chitsanzo kuti muyesedwe. Ngati mawonekedwe a makina a mzere umodzi woyesera mu chitsanzo chobwerezabwereza sakukwaniritsa zofunikira, gulu la mapaipi lidzawunikidwanso ndipo njira yothanirana ndi kulephera idzachitika.
8. Kuuma kwa Brinell
Choyesera kuuma kwa Brinell chimagwira ntchito pokanikiza mpira wachitsulo wa mainchesi odziwika bwino pamwamba pa chitsanzo pa liwiro lodziwika bwino pansi pa mphamvu yoyesera yodziwika bwino. Kenako mphamvuyo imachotsedwa mphamvu yoyesera yodziwika bwino ikasungidwa kwa nthawi inayake. Kuuma kwa chitsulo cha Brinell kumawonetsedwa ngati kupanikizika kwapakati komwe kumagwiritsidwa ntchito pamwamba pa malo ozungulira a indentation. Mayeso a kuuma kwa Brinell sakhudzidwa ndi kusiyana kwa microscopic kapena kusagwirizana kwa kapangidwe kake mu chitsanzocho. Powerengera chiŵerengero cha malo opindika ndi katundu wogwiritsidwa ntchito, chimayesa moyenera zinthu monga ductility ndi kukana kutopa, ndipo nthawi zambiri chimagwiritsidwa ntchito ngati muyezo wowongolera khalidwe la mafakitale.
Kuuma kwa Brinell kwa mapaipi achitsulo opangidwa ndi centrifugal sikuyenera kupitirira 230 HBW, ndipo kuuma kwa Brinell kwa mapaipi achitsulo opangidwa ndi ductile osakhala a centrifugal, zolumikizira ndi zowonjezera sikuyenera kupitirira 250 HBW. Malo omwe akhudzidwa ndi kutentha kwa zigawo zolumikizidwa amaloledwa kukhala ndi kuuma kwa Brinell kokwera.
9. Kapangidwe ka mankhwala a chitsulo chosungunuka, kuzindikira kwa spectral
Njira zowonera zitha kusanthula zomwe zili muzinthu zofunika monga silicon ndi magnesium mu chitsulo chosungunuka nthawi yeniyeni (mwachitsanzo, kuchuluka kwa silicon komaliza kumakhudza mwachindunji kulimba kwa chitsulo chosungunuka cha ferritic kutentha kochepa), m'malo mwa njira zachikhalidwe zamakemikolo zoyesera mwachangu ndikuwongolera kusintha kwa njira yopangidwa kale. Poyesa kufalikira kwa zinthu monga kaboni ndi sulfure, timatsimikiza kuti kuchuluka kwa graphite nodularity (kuchuluka kwa spheroidization ≥90%) kukukwaniritsa mphamvu yofunikira yomangirira (≥420 MPa) ndi kutalika (≥10%). Kuyang'anira kapangidwe ka chitsulo nthawi yeniyeni panthawi yopangira kumachepetsa zinyalala ndikukweza ubwino wamkati wa mapaipi ndi zolumikizira zachitsulo zosungunuka.
Zofunikira pakulamulira zigawo zazikulu za chitsulo chosungunuka pambuyo pa spheroidization
