Centrifugal ninini - ano o ka loaa ana pololei laina i

Centrifugal ninini - he papa hana no ka manufacturing laina i ka hoike ana, a ua ma muli o ka hopena o centrifugal ikaika ma luna o ka ahakanaka i hoʻoheheʻeʻia o ka mea. Foundry, ua hana i ka hana o ka hoʻokino laina i a me ka apuupuu ka hoike ana, ua he ākeaʻano o kāu kiʻina hana o ka ninini: ole, i loko o ke one-lepo ka hopena he kūikawā nahaehae ninini,, ma lalo o ka puʻuwai, etc. Akā, i ka mea e like ai loaa a pau e pono ninini mea centrifugal ninini.

Ma o Mānoa, ka iaoiaeii ninoieo i loko o ia ma centrifugal ikaika i ka mea i hoʻoheheʻe uniformly hohola ma luna o ka pā ili o ka punahelu, a crystallizing ano he hakahaka me ke koi 'ia kiko'î. Mai Mai manaʻo i kēia iaoia mea pili wale i ke hooheheeia, a me ko lakou oka. I ka mea, hoolei iho la ea huahana ua lilo unusually he ākea. Akā, Ka lula ea Ke i ka helu o ka hiʻona e pono e e noonoo i ka hana ana me ia i ka wa. Lula ka pahu kui ua pinepine lawe mai ma lalo o ka puʻuwai, a hoakaka kūikawā huahana miomio.

Ma ka hapanui o na hihia, nāʻano o ka ninini e hoʻohana i ka paka metala ka hoike ana. Penei, centrifugal ninini loaʻa paha kekahi mau pono :. No puha voids a me slag inclusions ma ka kūpono e kipaku, kiʻekiʻe-pa apŘ mea, mahuahua metala Wear ia'ku, a ua loaʻa ma kaʻaʻahu 'ole, etc. ka papa kuhikuhi pono o kēia hana i kapa ia mea makauliʻi ma ka workpiece, a he nui ka ho'ēmiʻana i loko o ka manaʻo pohihihi o ke kaʻina holoʻokoʻa kaʻina (aie i ka maximal kokekau e hoolei ana i ka hoʻopauʻana o ke huahana).

Centrifugal ninini i ka helu o ka "hua". Mau nā: loaa paʻewa ai noa surfaces o ka workpiece, i ka welelau o ka pae kaawale mea 'ano apau loa kiʻekiʻe kāki (aie i ka māhuahua olelo o dimensional pololei).

Special machines i hoʻohana 'ia ma ka centrifugal ninini hana. Ka mea, oko ma ke ala e hiki aku ana i ka iho (axis) o ke kuapo - vertical, papamoe, a me kaʻaui (axis) (i ka oiaio, ke i hala ua kākaʻikahi i hoʻohana). Machines me vertical (axis) hoʻohana i ka paka liʻiliʻi-lōʻihi billets me ka nīnūnēʻokoʻa o nāʻanuʻu (apo, Pistons, lole a me ka mea e like). Machines me ka papamoe (axis) o ke kuapo ae, e loaa loa-lōʻihi kiʻekiʻe-miomio ka hoike ana a me ka pā mānoanoa o ka hoʻokahi. Like me hoomakaukau ma ke ano o ka nou ana la o-hao paipu. Kēia papa hana o ka loa, he pono ole. E ho ohana i centrifugal ninini hiki paka heʻohe kani me ka pa o ka 80 a hiki i 300 mm o (ke kaumaha ma muli o ka lako a pan i hoʻohana). Ka mea wale nō mea i 'oe e maopopo leʻa malama i ka manao o ka mea e me keia hana, maloko stress ia lŘlŘ i loko o ka laina i. No laila, ma hope o ka loaa ana ka hoike ana e pono ai, e hoʻomaka annealing.

centrifugal ninini hana, a ua hoomakaukauia no nā preform wahi, a lakou i ke kino o ke kipi. No kaulana miomio ninini iaoiaeii ua hoʻohana 'ia i loko o ka? Iecaianoaaiiie o billets mai ole-ferrous ke hooheheeia (i kēia papa hana e leie aku oe e hoola pipiʻi mea).
