Mavharuvhu ekukanda mavharuvhu anogadzirwa nekukanda.Kazhinji, kuyerwa kwemavharuvhu ekukanda kwakadzikira (sePN16, PN25, PN40, asi kunewo akakwira-pressure, anogona kusvika 1500Lb, 2500Lb), uye mazhinji emhando dzawo ari pamusoro peDN50.Mavharuvhu eForged anogadzirwa uye anowanzo shandiswa mumapaipi egiredhi epamusoro ane diki diki, kazhinji pazasi DN50.
1. Kukandira
1. Kukandira: Inzira yekunyungudutsa simbi kuita mvura inosangana nezvimwe zvinodiwa uye kuidira muforoma.Mushure mekutonhora, kusimba, uye kuchenesa, kukanda (chikamu kana chisina) chine chimiro chakafanotemerwa, saizi uye kuita kunowanikwa.Iyo yakakosha tekinoroji yemazuva ano maindasitiri ekugadzira michina.
2. Iyo yakagadzirwa-yakagadzirwa mvere inodhurawo, uye inogona kuratidza kushanda kwayo kwehupfumi kune zvikamu zvine maumbirwo akaoma, kunyanya nemakumbo akaoma emukati;panguva imwe chete, ine yakafara kuchinjika uye zviri nani nzwisisika michina zvinhu.
3. Zvishandiso (zvakadai sesimbi, huni, mafuta, zvinhu zvekuenzanisira, nezvimwewo) uye midziyo (yakadai sesimbi yesimbi, misanganiswa yejecha, michina yekugadzira, michina yekugadzira, shakeout machines, pfuti inoputika, mahwendefa esimbi, nezvimwewo) inodiwa pakugadzira kugadzirwa ) Yakawanda, uye ichaburitsa huruva, gasi rinokuvadza uye ruzha uye kusvibisa nharaunda.
4. Kukandira imhando yesimbi yekupisa tekinoroji yakabata vanhu kare, ine nhoroondo yeanenge makore 6000.
Muna 3200 BC, kukanda matatya emhangura kwakaonekwa muMesopotamia.Pakati pezana ramakore rechi 13 BC nezana ramakore rechi 10 BC, China yakapinda muzuva remazuva ekukanda bhuronzi.
Hunyanzvi hwasvika padanho repamusoro, senge 875 kg Simuwu Fangding Ding kubva kuShang Dynasty, iyo Zenghou Yizun ndiro kubva kuWarring States Period, uye girazi rinopenya kubva kuWestern Han Dynasty vese vanomiririra kukanda kwekare.
chigadzirwa.Kuumba kwepakutanga kwakapesvedzerwa zvikuru nemidziyo yehari, uye zvizhinjisa zvezviumbwa zvaiva maturusi kana kuti midziyo yokurimwa kwekurima, rudzidziso, uye upenyu.
Rudzi rweunyanzvi rwakasimba.Muna 513 BC, China yakakanda simbi yekutanga pasi rose (inorema 270 kilograms), iyo inogona kuwanikwa muzvinyorwa zvakanyorwa.
Kuma 8th century, Europe yakatanga kugadzira iron castings.Mushure meRevolution Revolution muzana ramakore rechi 18, kukanda kwakapinda munguva itsva yebasa kumaindasitiri makuru.
Muzana remakore rechi20, kukurumidza kukura kwekukanda kwakagadzirwa.Nodular cast iron, inogadzika simbi yakakandwa, Ultra-low kabhoni Stainless simbi, aruminiyamu mhangura, aruminiyamu silicon, uye aruminiyamu-magnesium alloys akagadzirwa zvakatevedzana.
Kukandira simbi zvinhu zvakaita setitanium-based uye nickel-based alloys, uye yakagadzira nzira nyowani yekupinza grey cast iron.Mushure memakore ekuma1950, kuenzanisira kwepamusoro-soro kwejecha rakanyorova kwakaonekwa,
Kemikari kuomesa jecha modhi uye kugadzirwa kwepakati, kusarudzika kudzvinyirira modhi, kumwe kukanda kwakakosha, kuputika kwepfuti uye humwe hunyanzvi hunyanzvi.
5. Kune akawanda marudzi ekukanda, ayo akakamurwa kuita: ①Zvemazuva ose kukanda jecha, kusanganisira 3 marudzi ejecha rakasvibira, jecha rakaoma uye jecha rakaomeswa nemakemikari.②Kukanda kwakakosha, zvinoenderana nemhando yemhando, inogona kukamurwa kuita yakakosha kukanda nejecha remamineral jecha uye matombo sechinhu chikuru chekuenzanisira (sekukanda mari, kukanda ivhu, kukanda musangano kukanda goko, kukanda kwakashata, kukanda kwakasimba, kukanda ceramic) Etc.) uye yakakosha kukanda nesimbi sechinhu chikuru chekuumbwa (senge simbi mold casting, pressure casting, kuramba ichikanda, low pressure casting, centrifugal casting, etc.).
.Iyo mold inogona kukamurwa kuita jecha, simbi, ceramic, ivhu, graphite, nezvimwewo, zvichienderana nehuwandu hwenguva dzekushandisa.Kune inoraswa, semi-yechigarire uye isingaperi, mhando yekugadzirira mold ndicho chinhu chikuru chinokanganisa kunaka kwekukanda;②Kunyunguduka nekudururwa kwesimbi dzakakandwa, simbi dzakakandwa (casting alloys) dzinonyanya kusanganisira simbi yakakandwa, simbi yakakandwa uye simbi isina-ferrous;③ Kukandira kugadzirisa uye kuongorora.Kugadziriswa kwekukandira kunosanganisira kubviswa kwemitumbi yekunze pahupamhi uye pamusoro pekukanda, kubviswa kwekudururira makwikwi, kufoshorosa maburrs uye drape seams, pamwe nekupisa kupisa, kuumba, anti-ngura kurapwa uye rough machining.Kupinza pombi valve

Nortech ndeimwe yeanotungamira maindasitiri ekugadzira mavharuvhu muChina ane quality certification ISO9001.
