Te whakaiti i te rahunga o ngā hiri pāmahana teitei

Ka whakaitihia te rahunga e ngā hiri ā-ringa pāmahana teitei mā te whakahaere kaha i te kiriata wai i waenga i ngā mata hurihuri me ngā mata tūmau, ka ārai i ngā huringa āhua e arahi ana ki te rere maroke.Ngā hiri miihini paerewahe maha ngā wā ka hē te wai e pupuhihia ana hei kohu—he mea noa tēnei ina whakahaerea te wai, ngā hauwaiwai māmā rānei i runga ake i te 150°C (300°F). Mā te whakamahi i te mahi whakarewa matatau me te āhua mata hiri kua arotauhia, ka tere ake te horapa o te wera kua puta mai i ngā momo pāmahana teitei, ā, ka mau tonu te kiriata wai pumau.

Hei tāpiri atu, ka whakaitihia e ēnei hiri ngā ahotea ā-pūkaha e pā ana ki te wera nui. Ko ngā hiri pana paerewa e whakawhirinaki ana ki ngā mowhiti-O hihiri ka taea te whakapakeke, te whakaputa, te rewa rānei, ka whakairihia ngā mata o te hiri, ka turuturu. He maha ngā wā ka whakakorehia ēnei elastomers hihiri e ngā hoahoa pāmahana teitei hei painga mō ngā pupuhi whakarewa ngāwari, kia mau tonu ai te uta o te mata ahakoa tepūwero papuka pāngia e te whakawhanuitanga wera.

Ko ēhea ngā āhuatanga whakahaere e ārahi ana i te rahunga o te hiri wera

He maha ngā āhuatanga whakahaere ka tere ake te pakaru o te hiri wera mena kāore e arohia tika e te hoahoa hiri. Ko ngā pāmahana tukanga neke atu i te 200°C (392°F) te tūmomo mōrearea tino tika, ka whakaiti i ngā huānga hiri tuarua paerewa me te whakarerekē i te matotoru o te kiriata wai whakahinuhinu. I ēnei pāmahana, ka tino whaiti te tawhiti i waenga i te pēhanga whakahaere o te wai me tōna pēhanga kohu, ka piki ake te mōrearea o te kanapa.

Ko ngā whakawhiti wera, te ru wera rānei, ka raru ai te mahi. Ina pāngia te papu e ngā pikinga tere o te pāmahana neke atu i te 50°C i te meneti, ka pāngia pea ngā mata hiri paerewa e te horapa wera kore taurite, ka arahi ki te hē o te mata me te turuturu tere. Hei tāpiri, ko te pupuhi i ngā warowaihā i ngā pāmahana tata ki te 175°C (347°F) me runga ake ka puta te mōrearea o te kōkō, ka waikura te wai i te taha hau o te hiri, ka hanga he paru whakakoi e aukati ana i te nekehanga o te hiri, ka whakangaro hoki i ngā mata kua taupokina.

He aha te Whakamārama i te Hiri Ā-ringa Pāmahana Teitei

Ko te tautuhi i tētahi hiri miihini pāmahana teitei me titiro ki tua atu i ngā rahinga taketake ki ngā rauemi matua me te hangarau hanganga.

Me whakataurite e te ripanga mahi ngā hiri pana paerewa ki ngā pupuhi whakarewa i whakarewahia ki te taha me ngā hiri kore-pa kua pania ki te hinu hau. Ko ngā inenga matua ko ngā paepae pāmahana mōrahi, te ngawari ki te piko o te mata, me te mōrearea o te whakairi o te mowhiti-O hihiri.

Ko ēhea ngā momo rahunga e tino kitea ana i te pāmahana teitei

Ko te momo rahunga tino kitea i ngā pāmahana teitei ko te tirotiro wera. Ka puta tēnei āhuatanga ina nui ake ngā pāmahana o te mata o te wai i te pūmahana kohua o te wai mā te 10-15°C noa iho, ka mura te kiriata wai. Ko te huringa tere o te whakamahana me te whakamatao ka puta he ngenge wera nui, ka hua ake he kapiti porowhita moroiti puta noa i te mata hiri e mahi ana pērā i ngā taputapu tapahi, ka tere te whakangaro i te mata o te taha ke.

Ko ētahi atu momo rahunga pāmahana teitei e kitea whānuitia ana ko te pupuhi waro me te whakaputanga elastomer. Ka puta te pupuhi ina uru ngā warowaihā taumaha ki roto i ngā pūwero o te mata o te hiri waro; i te pikinga o te pāmahana, ka whānui te wai kua mau, ka pakaru te mata o te waro. Ka puta te whakaputanga elastomer ina whakangawarihia ngā mowhiti-O e ngā pāmahana teitei, ka meinga te pēhanga tukanga kia panaia te elastomer ki roto i ngā āputa taputapu, ka tangohia te arai tuarua o te hiri, ā, ka puta te turuturu tonu.

Ko te tohu i tētahi hiri pāmahana teitei ka tīmata me ngā whakaurunga tika: te pāmahana pouaka whakakī, te pēhanga hihiri mōrahi, te tere o te pou (RPM), me te tawhā pēhanga kohu tika o te wai tukanga. Mō ngā tono whakamahine taumaha e mahi ana ki te 40 pae (600 psi) me te 400°C, me tatau e ngā kaihangarau te whakaputanga wera e matapaetia ana i ngā mata hiri hei whakatau i te kaha whakamatao e hiahiatia ana.

Me whai whakaaro ngā mahi rahi ki te whānui o te wera o te pou papu me te anga. Me whakarato te rūma hiri i te āputa radial e tika ana hei whakauru i ngā huihuinga pupuhi whakarewa nui ake, me te tuku i te rere o te wai kia ranea. Mena he kikī rawa te āputa, kāore e taea te memeha te wera, ā, ka pakaru te hiri ahakoa tōna taumata whakarewa.

He aha ngā mahi tāutanga, tīmatanga, mahere horoi, tirotiro, me te aroturukitanga āhua e whai tikanga ana

He mea nui ngā tikanga tāutanga me te tīmatanga. Me tino ma te tāutanga o ngā hiri pāmahana teitei, nā te mea ka taea e ngā paru te aukati i te hononga pai o ngā mata. I te wā tīmatanga, me tika te whakaputanga o te pūwero o te papu kia kore ai e maroke te rere, ā, me whakamahana haere i te pāmahana (te whakamahana āta) kia kore ai e pāngia e te ru wera o ngā mata carbide.

Ko te pūnaha whakahaere taiao, e tautuhia ana e ngā mahere paipa API 682, te pūtake o te hiri. E kiia whānuitia ana ko te Mahere API 23 te mea tino whai hua mō ngā tono whāngai wai wera me te pōro, e huri ana i te wai mā roto i te pouaka whakamatao, ā, e whakaiti ana i te kawenga wera i runga i te pūnaha wai whakamatao o te tipu tae atu ki te 80% ki te whakataurite ki te Mahere paerewa 21. Mō ngā warowaihā wera, he maha ngā wā ka whakamahia he tinei mamaoa Mahere 62 ki te taha hau o te hiri hei ārai i te waikura me te kōkō. Me uru ki te aroturukitanga o te āhua te aroturuki i te pāmahana o te wai; ko te pikinga tonu o te +10°C ki runga ake i te turanga kua whakaritea he tohu pono moata o te mamae o te mata, o te paru rānei o te pouaka whakamatao.

Me pēhea te whiriwhiri i te hiri mīhini pāmahana teitei pai rawa atu

Ko te whiriwhiri i te hiri miihini pāmahana teitei tino pai me whakataurite i te whakapaunga whakapaipai o mua me ngā utu whakahaere roa o te pūnaha papu. Mā te whiriwhiri tika ka honoa ngā kaha whakarewa me te hoahoa o te hiri ki ngā āhuatanga wera motuhake o te tukanga, kia roa ai te mahi.

Me pēhea te paunatia te utu katoa o te mana whakahaere me te tiaki

Ina paunatia te utu katoa o te mana whakahaere (TCO), me titiro ngā kaiwhakahaere tipu ki tua atu i te utu hoko tuatahi. Tērā pea ka piki ake te utu o mua o tētahi hiri whakarewa kounga teitei kua whakapirihia ki te taha me te hiri tuarua o te karāhe ngāwari ki te 2 ki te 4 ngā wā ki te whakataurite ki tētahi hiri pana paerewa. Heoi, ka tere te whakakorenga o tēnei utu whakapaipai mā te whakakorenga o te wā whakatā kore i whakaritea.

Mā te pakaru kino o te hiri kotahi i roto i tētahi wāhanga whakamahine pāmahana teitei ka ngaro pea te hua o te $10,000 ki te $30,000,mahi tiaki, me te horoi taiao. Hei tāpiri, he nui te pānga o ngā ratonga whakamatao ki ngā utu tiaki. Ka taea e te hiri kua tīpakohia hē e whakawhirinaki ana ki tētahi pūnaha whakamatao tuwhera-porowhita koretake te whakapau i te neke atu i te $15,000 ia tau i roto i ngā utu ratonga anake, engari ko te haumi ki tētahi hiri pāmahana teitei e honoa ana ki tētahi pūnaha Mahere 23 porowhita-kati ka hua mai he hokinga tere o te haumi.
