Kupu Whakataki mō te Topenga Ngongo Pūrerehua

Ka hangaia e mātou tēnei rawhi mō ngā pūnaha e wetekina ai ngā rawhi noa e ngā huringa pāmahana me te wiri. Ko te mea nui ko te puranga puna kōpae i hangaia ki te SS301. Ina whakakīia te tīwiri, ka pēhia te puranga puna. Mena ka whānui, ka whakaiti rānei te ngongo, ka roa rānei te wā e mau ai te rapa, ka pana whakamuri te puranga puna kia tata tonu te taumahatanga o te whitiki. Ko te tikanga kāore koe e hiahia ki te whakakī anō i ngā wā katoa, ā, ka roa ake te pono o te hiri.

Ngā Rauemi me ngā Taipitopito Hanga o ngā Rawhi Ngongo Tūmau

Te whitiki, te whare, me te uhi pito: SS304 he kowiri tira – he ātete pai ki te waikura, he paerewa mō te nuinga o ngā taiao ahumahi.

Tīwiri: Kowiri tira SS410. He momo martensitic tēnei, he mārō atu i te SS304. He pai ake te ātete ki te whakakorikori miro, inā koa me huri tonu.

Puna kōpae: SS301, he kaha ake te kaha whakaputa i te SS304. I roto i tā mātou whakamātautau pēhanga i te taipana 8 N·m, i hoki te puranga puna ki te neke atu i te 99% o tōna teitei taketake i muri i te pēhanga – nō reira ka mau tonu te pānga utu.

Tukanga Hanga Rawhi Ngongo Momo Amerika

Ngā Herenga Paipa Pāreti Whakamahana Kaha Hanganga

E wha ngā rivet e mau ana te whare ki te whitiki. I whakamātauhia e mātou te taipana whakangaro – te wāhi ka tīmata te takahuri o te whare – ā, e neke atu ana i te 25 N·m. He nui ake tēnā i tā te nuinga o ngā rawhi paerewa e tukuna ana, kia taea ai e ia te tu atu i te wiri nui me te kore e paheke te whitiki.

Raina Rawhi Whitiki Rino me te Hiri

He arai kei roto i te whitiki. E rua ngā mahi: ka tiaki i te mata o te ngongo mai i te pakaru, ā, ka horahia te kaha piri kia ōrite ki te porowhita. Ka āwhina tēnei ki te karo i te pēhi ā-rohe, ā, ka hoatu he hiri ōrite ake.

Tāutatanga o te Rawhi Paipa Momo Amerika

Ngā Whakamahinga Noa o ngā Herenga Ngongo Pāreti

Ka whakamahia ēnei here e ā mātou kiritaki ki:

Te whakamatao miihini me ngā raina turbo i runga i ngā taraka taumaha

Ngā raina whakahoki hinu waipēhi i roto i ngā taputapu hanga

Ngā hononga paipa i roto i ngā tipu maimoatanga wai

Ngā raina wahie me te hau i runga i ngā miihini moana

Te whakawhiti wai whānui ina rerekē te pēhanga

He aha i whiriwhiri ai i tēnei i te rawhi taraiwa-noke paerewa?

Ka hoatu e te rawhi noa he porowhita pumau – ki te ngohengohe, ki te whakaiti rānei te ngongo, ka heke te kukū. Ka whakatikatikahia tēnei i roto i te puranga puna. He rite tonu te tāutanga tuatahi – ka huri noa koe i te tīwiri ki te uara kua tohua e koe. Mai i taua wā, ka pupuri te rawhi i te kaha māna ake, i roto i te awhe mahi o te puna.

Kua kite mātou i ngā kaiwhakamahi e whakapoto ana i ngā wā tiaki kia haurua mā te huri noa ki tēnei momo. Ehara i te mea he taputapu whakapaipai; he otinga ā-ringa mō tētahi raruraru ā-tinana – te nekehanga wera me te ngokingoki rauemi.

Ngā Pātai Auau

P1: He aha te tikanga o te "pēhanga pumau" i roto i tēnei rawhi?

Ko te tikanga, kāore te rawhi e whakawhirinaki anake ki tētahi porowhita pumau. Ka whakaea e te puna kōpae kua utaina i mua i roto i te whare te whakawhanuitanga wera, te whakahekenga, te huinga pēhanga ngongo rānei. Ka pana whakamuri te puna kia mau tonu te kaha rawhi i roto i tētahi awhe ōrite, ka whakaiti i te hiahia mō te whakakī anō.

Q2: He pēhea te mahi a te puna kōpae i roto i te wā?

I roto i tā mātou whakamātautau pēhanga i te taipana 8 N·m, i whakahokia mai e te puranga puna SS301 neke atu i te 99% o tōna piko taketake i muri i te tukunga. Ka mau tonu taua tere whakahoki i raro i ngā kawenga mahi noa, nō reira ka mau tonu te pānga utu mō te roa o te ora ratonga.

Q3: He aha i hangaia ai te tīwiri ki te SS410, kaua ki te SS304?

He maitai kore waikura martensitic te SS410 – he pakeke ake, he ātete hoki ki te kakahu i te SS304 austenitic. Mā tēnei ka whakaitihia te mamae o te miro ina pēhia tonutia te rawhi, ina whakamahia rānei he taipana tāutanga teitei, inā koa i ngā āhuatanga tiaki mara.

Q4: He aha ngā rahi me ngā takai e tukuna ana?

E 16 ngā rahi kei a mātou, mai i te 32–54 mm ki te 230–252 mm, he whānui katoa te whitiki 15.8 mm. Mōkihi paerewa: 10 ngā wahi mō ia pēke kirihou, 100 ngā wahi mō ia kātene kaweake. He SS304 ngā whitiki, ngā whare, me ngā taupoki pito katoa.

Q5: Ko ēhea ngā ahumahi e whakamahi pinepine ana i tēnei rawhi?

Ko ngā whakamahinga noa ko ngā raina whakamatao taraka taumaha me ngā raina turbo, ngā pūnaha waipēhi i roto i ngā taputapu hanga, ngā hononga paipa maimoatanga wai, ngā raina wahie/hau moana, me te whakawhiti wai whānui i te wā e rerekē ana te pēhanga, te pāmahana rānei. Ka whakamahia hoki i roto i ētahi hiri pūnaha putanga hau hōia me te miihini.
