Anthu ambiri akamva 'pampu ndi valavu zoponyera ma valve' amafanizira chitsulo chaukali. Ndiko kulakwitsa koyamba. Nkhani yeniyeni ili mu geometry yomwe simungawone kuchokera kunja - ndime zamkati, kusintha kwa makulidwe a khoma, malo okhalamo. Pezani izo zolakwika, ndipo pampu yanu yogwira ntchito kwambiri ndi yokwera mtengo chabe. Sizokhudza kupanga mawonekedwe; ndi za kupanga mawonekedwe omwe amasunga kupsinjika, kukana dzimbiri, ndikupulumuka kutopa kozungulira kwazaka zambiri, nthawi zambiri m'malo omwe simungafune kupitako. Kusiyana pakati pa kujambula ndi kujambula kogwira ntchito ndi kumene ntchito yeniyeni imachitika.
The Foundry Floor Reality
Tiyeni tikambirane zipangizo kaye. Zochulukira zimayitanira CF8M yosapanga dzimbiri pa valve yowononga. Zikumveka molunjika. Koma kuwotcherera kwa CF8M ndi kukana kwa dzimbiri kumatengera zomwe zili ndi ferrite komanso momwe mumawongolera kuzizira mu nkhungu. Ndawonapo magulu pomwe chemistry inali yabwino pamapepala, koma kuziziritsa kudatsitsidwa ndi tsitsi, zomwe zimatsogolera ku mpweya wa sigma pamalire a tirigu. Ziwalozo zidapambana mayeso oyambilira koma zidapanga ming'alu yaying'ono patatha miyezi isanu ndi umodzi kumunda. Kulephera sikunali mu kusankha kwazinthu, koma mu kayendetsedwe ka kayendetsedwe kazinthuzo. Ndiwo mtengo wobisika.
Apa ndipamene makolo a foundry amafunikira. Sitolo ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., ndi zaka makumi atatu mu zipolopolo ndi kupanga ndalama, sikungogulitsa zitsulo. Iwo akugulitsa ndondomeko kukumbukira. Iwo awona momwe kusintha pang'ono kwa njira yolowera pazitsulo zovuta zoponyera muzitsulo zosapanga dzimbiri zingalepheretse kuchepa kwa porosity muzu wa tsamba-mtundu wa chilema chomwe chimangowonekera pansi pa X-ray kapena, poipa kwambiri, kulephera koopsa.
