1. Te Kōwhiri i te Kōwhiringa Nohoanga Tika: PPL vs. Nohoanga-Metara

Ko te whiriwhiri i waenga i ngā whakapaipai PPL (Polyparaphenylene) me ngā whakapaipai Metal-Seated e whakawhirinaki ana ki te pāmahana mahi, ngā taumata matūriki pāpāho, me te akomanga hiri e hiahiatia ana.

2. Ngā Āhuatanga Hangarau mō ngā Taiao Wera Rawa

•Hoahoa Whakawhānui o te PōnatiNekehia te rūma tākai kakau kia matara atu i ngā rohe tinana pāmahana teitei. Ka tiakina e ngā tara whakamatao wera kua whakauruhia ngā rauemi tākai kakau (te karāhe ngāwari/mowhiti-V) me ngā kaiwhakaoho ā-ringa/aunoa mai i te wera paipa hihi, kia roa ai te ora o te mahi.
•Ngā Kete Tākai Belleville Utaina OraKa taea e te whānui me te whakahekenga wera te whakangāwari i te takai. Ka pupuri tonu ā mātou puranga puna kōpae Belleville i te pēhanga repe radial i runga i te huinga takai, ka whakakore i ngā turuturu wera, ā, ka tutuki hoki i ngā paerewa iti-tukunga API 641 / ISO 15848-1.
•Whakaora i te Whanuitanga Wera me te Horoi-ā-IhoKei ngā nohoanga whakarewa he pūkaha puna taumaha e mimiti ana i te whakawhanuitanga wera e puta mai ana i te wai, me te kore e herea he pōro. Ka horoia e te hoahoa waru koi te kohuke i te mata o te pōro i te wā e huri ana i te hauwhā-huringa.
•Ngā Paninga Mata Mārō HVOF MatatauMā te hangarau High-Velocity Oxygen-Fuel (HVOF) ka whakamahia te Tungsten Carbide, te Chrome Carbide rānei ki ngā mowhiti pōro me ngā mowhiti nohoanga, ā, neke atu i te 10,000 PSI te kaha o te here, ka eke ki te pakeketanga moroiti tae atu ki te HRC 70 mō te ātete ki te pakū kino.

5. Ngā Pātai Auau (Ngā Pātai Auau mō te Hangarau)

Q1: He aha te pāmahana whakahaere mōrahi mō ngā takirere pōro noho PPL me ngā takirere pōro noho whakarewa?

Ka mahi pono ngā nohoanga PPL (Polyparaphenylene) tae atu ki te 280°C–300°C (536°F–572°F) mō ngā wai ma me te mamaoa. Ko ngā takirere pōro e noho ana ki te konganuku me te mata pakeke HVOF (Tungsten Carbide, Chrome Carbide, Stellite rānei) he mea hanga mō ngā mahi tino kaha tae atu ki te 550°C–650°C (1022°F–1202°F) me ngā mea whakakoi.

Q2: He aha i hiahiatia ai he taupoki roa mō ngā takirere pōro pāmahana-tiketike?

Mā te taupoki roa ka nekehia te pouaka tākai kakau kia matara atu i te tinana paipa wera, ka whakamararatia te wera hihi. Mā tēnei ka noho tonu ngā hiri kakau (pērā i te karāhe ngāwari) i roto i tō rātou awhe pāmahana mahi haumaru, ka ārai i te hekenga wera, ā, ka tiaki i ngā kaiwhakaoho hiko, hau rānei mai i te wera nui.

Q3: Me pēhea te ārai i te maukati/te whakapataritari o te pōro i ngā pāmahana wera nui?

Ka whakahaerehia te whakawhanuitanga wera mā te whiriwhiri rauemi rerekētanga tika (te whakataurite i ngā tauwehenga whakawhanuitanga wera o te tinana, te pōro, me te kakau) me te whakauru i ngā pūkaha puna utaina-ora i muri i ngā mowhiti nohoanga. Ka pēhia ēnei puna hei mimiti i te whakawhanuitanga wera nui me te kore e whakanui ake i te taipana mahi, e kore hoki e herea ā-mīhini.
