He Whakaranu Whakamarara Kaha mō te Korehau – He Whakamārama mō te Hanganga me te Mātāpono Mahi
1. He aha i whiriwhiri ai koe i te hanganga kowiri tira?
Ko te maitai kore waikura (te nuinga ko te 304, te 316L rānei) te rauemi paerewa mō tēnei momo taputapu mō ēnei take e whai ake nei:
| Āhuatanga | Whakamārama |
|---|---|
| Ātete ki te Waikura | Ātete ki te whakaekenga matū mai i ngā rauemi waikawa/kawakore me ngā kaihoko horoi |
| Horoi Māmā | Ka ārai te mata maeneene i te kohikohi rauemi, e tutuki ana i ngā paerewa akuaku GMP |
| Kāore he poke | Kāore e tuku i ngā iona whakarewa ka poke pea i ngā rauemi, kia mau ai te parakore o te hua |
| Te pakari | He roa te ora ratonga o te kaha miihini teitei |
Kei roto i te maitai kore waikura 316L he molybdenum tāpiri, e whakarato ana i te ātete pai ki te waikura pūhaumāota. E taunakihia ana mō ngā tono e pā ana ki te tote, ki ngā rauemi waikura nui rānei.
2. Te Wehenga o te Hanganga Matua
Ko te mīhini whakamarara kaha korehau maitai he hanganga momo-kantari toru-poro , e whā ngā pūnaha matua:
2.1 Pūnaha Ā-ringa – Te "Angaanga" o ngā Taputapu
Anga Kāniwha: He mea whakarewa mai i ngā pereti maitai taumaha, e tautoko ana i ngā tikanga whakaoho katoa me te taumaha rauemi, kia mau ai te pumau me te kore e wiri i te wā e mahi tere ana.
Pūnaha Hiki Waipēhi: He mea tito mai i ngā rango waipēhi, ngā piston, me te waeine hiko waipēhi. Ka taea te whakaara me te whakaheke poutū i te taupoki, kia māmā ai te utu, te horoi, me te whakawhiti tāke. Ka taea te whakarite i te teitei me te tere o te hiki kia rite ki ngā whakaritenga o te tukanga.
2.2 Pūnaha Whakaoho me te Marara – Te "Ngākau" o ngā Taputapu
Koinei te wāhanga matua e whakatau ana i te whai huatanga o te whakaranu, mā te whakamahi i te hoahoa nekehanga matū "hurihuri aorangi + hurihuri tere-nui" :
| Wāhanga | Momo Nekehanga | Momo Impeller | Mahi Matua |
|---|---|---|---|
| Toka tere-iti (waenganui) | Te hurihanga aorangi (huri noa i te tuaka o te tāke) | Mata waru "Maunga" | Ka waru i ngā rauemi mai i te pakitara/raro o te tāke, ka ārai i ngā rohe mate, ka pana i ngā rauemi ki te rohe tere-rahi |
| Ngā toki tere-teitei ×2 (taha) | Hurihanga tere-teitei (huri noa i tōna ake tuaka) | Pūrerehua impeller + kōpae marara | Ka whakaputa i te kaha kutikuti teitei, ka wawahi i ngā paura e kohikohi ana, ka tutuki te horapa taumata-micron |
Ngā Whakatakotoranga Matua: Me eke te tere o te pito o te kōpae marara tere-teitei ki te 20 m/s, neke atu rānei , kia pai ai te marara o ngā paura nano-tauine. Mā te puku auau rerekē (VFD) ka taea te whakarerekē tere kore-taahiraa.
2.3 Pūnaha Korehau – Te Whakapūmau i te Kiato o te Hua
Papu Korehau: He momo hurihuri, he momo mowhiti wai rānei, me te tere papu e rite ana ki te rōrahi o te tāke.
Pūrere Hiri: Parenga takirua me te hiri miihini + hiri hinu, kia taea ai e te korehau i roto i te tāke te eke ki te -0.098 MPa (pēhanga ine).
Mahi: Ka whakamahia te korehau i te wā e whakaohooho ana hei tango i ngā mirumiru hau mai i te rauemi, hei ārai i ngā āputa i roto i te hua whakamutunga, hei whakarite hoki i te kaha o te piri o te hiri me te mātotoru o te mata.
2.4 Ngā Pūnaha Āwhina – Te Whakapai Ake i te Wātea o te Mahi
Ngā Tāke Nekeneke: He wira kei raro. Ka taea te hono i te mīhini kotahi me ngā tāke maha hei whakaputa tauwhitiwhiti.
Whakahaere Pāmahana Kua Whakakīia ki te Kōpaki: He kōpaki o waho kei roto i te tāke hei whakahaere i te wai whakamatao, i te mamaoa rānei, kia tika ai te whakahaere i te pāmahana. Ko te hanga hiri silicone me whakahaere i te pāmahana i raro i te 40°C hei ārai i te hononga whakawhiti i puta mai i te wera.
Kaiwhakaputa Waipēhi: Ngā taputapu tāpiri hei whakaputa i te whakapiri matotoru kua oti mai i te tāke whakamarara mō te whakakī i muri mai.
3. Tukanga Mahi (Te Whakamahi i te Hanga Hiri Hiri hei Tauira)
Te Utu → Te Whakaranu Waru Tere-iti → Te Marara Tere-tiketike → Te Tango Hauhanga Korehau → Te Tukunga
│ │ │ │ │
Wai + Paura Ārai i te piri o te pakitara Wāwāhi i ngā mea e whakaemi ana Tangohia ngā mirumiru Te whakaputa waipēhi
Ngā Hipanga Taipitopito:Te Whakautu: Ka utaina ngā rauemi turanga (hei tauira, te kāpia 107), ngā paura (konupūmā kāponāte, te silica), me ngā tāpiringa ki roto i te tāke e ai ki te hanganga.
Whakaranu Tere-iti: Ka mahi te mata waru i te 20-60 rpm, e pana ana i te rauemi ki waenganui.
Te Marara Tere-Tiketike: Ka huri ngā kōpae marara i te 0-1500 rpm, ka whakaputa i te kutikuti teitei hei wawahi i ngā paura e kohikohi ana ki raro ki te taumata maikorona.
Te Whakakore Hauhanga: Ka whakamahia tonutia te korehau i te wā e horahia ana hei tango i ngā mirumiru hau kua mau mai i te tāke.
Te Tukunga: Kia oti te horapa, ka nekehia te tāke ki tētahi extruder waipēhi hei tuku i te hua kua oti.
Whakamutunga
Mā te hangarau tika tae atu ki te tango hau toru-poro, te tango hau korehau, me te hiki waipēhi, ka tino whakatauhia e te mīhini whakamarara kaha korehau maitai ngā uauatanga o te ahumahi o te whakamararatanga ōrite me te tango hau o ngā rauemi matotoru. Ko te mārama ki tōna hanganga me te mātāpono mahi te tūāpapa mō te kōwhiringa tika me te mahi whai hua.
