Ngā Take Matua mō te Whakarite i te Hototahi ki te Hiri Mīhini

Tātaritanga Wai Whānui

Ko te tātaritanga wai tino pai te tūāpapa mō te mahi hiri miihini angitu. Me mārama ngā kaihangarau ki ngā āhuatanga o te wai tukanga hei whiriwhiri i ngā rauemi hiri hototahi. Kei roto i tēnei tātaritanga ētahi tawhā nui. Ka tirotirohia e rātou tete tauhohenga a te wai ki ngā huringa pāmahana. Ka taea e ngā pāmahana teitei te meinga ngā wairewa kia kore e pai hei hinu whakahinuhinu. Ka memeha pea ngā hauwaiwaro māmā. Ka taupatupatu pea ngā tote me ngā matū whakakā. Ka pakaru pea ngā hinu. I tetahi atu taha, ko te pāmahana tino makariri ka arahi ki te whakapakeketanga me te matotorutanga teitei. Ka whakanui ake tēnei i ngā kaha kutikuti me te kino o te mata.

Ka whakaarohia e ngā kaitātari ia wāhanga o te wai. Ka aromatawaihia e rātou te āhua o te wai tonu. He mea nui te noho o ngā totoka i roto i te awa e papuhia ana. Me arotake marie ngā poke waikura, pērā i te H2S, i ngā pūhaumāota rānei. Mena he otinga te hua, he mea nui tōna kukū. Ka whakatauhia hoki e ngā miihini mēnā ka totoka te hua i raro i ngā āhuatanga katoa.

Ko te matotoru o te wai te mea matua hei whakaaroaro, inā koa i te pāmahana mahi. Koinei te tikanga whakahinuhinu. He maha ngā wā ka hiahiatia he huinga mata ngohengohe, mata mārō hoki mō ngā ratonga matotoru iti. Mā ngā wai matotoru teitei ka taea te whakahinuhinu i te kiriata wai katoa. Tērā pea ka whakamahia he huinga mārō, mārō hoki hei karo i ngā take pēnei i te pupuhi i roto i ngā rauemi ngohengohe. He mea nui anō hoki ngā āhuatanga me ngā kukū o ngā totoka whakatārewatia, ngā matūriki tioata rānei. I roto i ngā tono paru, poke rānei, ka taea e ngā matūriki mārō atu i te rauemi mata te kino. Me hiahia tēnei ki ngā rauemi mata mārō atu. Ka taea hoki e ngā wai e tioata ana, e tote ana rānei te kino nui ki ngā mata ngohengohe. He mea nui te hototahi matū o ngā rauemi. Ka pāngia ngā mata hiri e ngā wai tukanga rerekē. Ko ētahi he kaha te mahi, ā, ka taea te tauhohe matū ki ngā wāhanga o te rauemi. Kei roto i ēnei ko te rauemi turanga, te here, te whakakī rānei. He mea nui anō hoki ngā whakaaro wera. Ko ngā āhuatanga o waho (te wai e papua ana, ngā koti whakamahana/whakamatao, ngā mahere paipa) me ngā āhuatanga o roto (te waku, te pōrearea) ka pā ki te pāmahana o te mata hiri. Ka taea e ēnei te arahi ki te tipu wera, te hoki whakamuri rānei. Ka taea hoki e rātou te whakangaro i te rauemi whakakī, te here rānei. Ko te koni wera nā ngā pikinga wera tuaka tētahi atu āwangawanga.

Ngā Tikanga Pai mō te Kōwhiringa Rauemi mō ngā Hiri Mīhini

He mea nui te whiriwhiri i ngā rauemi tika mō tete roa o te ora me te mahio ngā Hiri Mīhini. Me whiriwhiri e ngā Kaihangarau ngā rauemi e ātete ana ki ngā āhuatanga matū me ngā āhuatanga ā-tinana o te wai motuhake. Mō ngā tono tino waikura, pērā i ngā mea e whai waikawa kaha ana, e whai turanga kaha rānei, me whiriwhiri rauemi motuhake. Kei te wātea ngā mata karāhe waro waikawa. Kāore he whakakī kapia i roto i ēnei, he pai hoki ahakoa he iti ake te kaha ki te whakataurite ki ētahi atu momo karāhe waro. Heoi anō,karāhe silicon kua whakatōkia tikakua whakakapia nuitia rātou. He mea noa te whakamahi i te silicon carbide mō ngā mata mārō. He nui te kawe wera, te ātete ki te pakū, me te ātete ki ngā matū.

Ahakoa he pai ngā āhuatanga kakahu o te silicon carbide e honoa ana ki te tauhohenga, ko tōna ihirangi 8-12% o te konganuku silicon kore utu ka whakawhāiti i te ātete matū. Nā tēnei ka kore e pai mō ngā waikawa me ngā turanga kaha (pH iti iho i te 4, neke atu rānei i te 11). Ko te silicon carbide kua whakatōkia tika, e mōhiotia ana ko te silicon carbide kua whakatōkia-ake, ka tuku i te ātete matū pai ake. He silicon carbide tata katoa, kāore he konganuku silicon kore utu. Nā tēnei ka ātete ki te nuinga o ngā matū, ā, he pai mō te nuinga o ngā tono hiri miihini, tae atu ki ngā mea tino waikura. Hei tāpiri, mō ngā ratonga tino waikura kāore he konganuku e pai ana te hototahi matū, hei karo rānei i te utu nui o ngā konganuku utu nui, kei te wātea ngā hoahoa hiri kāore he wāhanga konganuku kua mākū.

Mō ngā wai tino waikura pērā i te waikawa hydrofluoric (HF), ka tūtohu ngā miihini i ngā huinga rauemi motuhake. Me whakamahi ngā mata hiri i ngā karaehe waro ātete matū me te karawaka silicon kua whakakīia ki te alpha. Me arotake ngā karaehe waro motuhake mō te hototahitanga me te pakari nā te mea he pōturi me te pēhanga o te waikawa hydrofluoric. Ko ngā perfluoroelastomers te huānga hiri tuarua e taunakitia ana. Ko ngā wāhanga whakarewa, pērā i ngā repe me ngā kara, ka whakamahi i ngā konganuku koranu teitei me te ātete waikura pai rawa atu.Monel® Alloy 400kua whakamahia i roto i ngā tono waikawa HF maha i mua.

Ka ātete ki te waikura, te horo, me ngā whakaekenga matū. He mea nui tēnei aromatawai wawe mō ngā taiao he wai whakakoi, he waikura, he wai pāmahana teitei rānei. Ka āwhina hoki ki te whakaaro me pēhea te pānga o ngā huringa o ngā āhuatanga wai nā te pēhanga me te pāmahana ki te kounga o ngā rauemi. Mā tēnei huarahi matatau, tae atu ki te whakamahinga o te Raru Aratau me ngā Pānga Tātari (FMEA), ka taea te tautuhi wawe me te whakaiti i ngā rahunga pea e pā ana ki te hototahi o ngā rauemi. Ka hua ake tēnei i te pono me te whai hua o te utu.

Ngā Tikanga Whakamātautau Taiwhanga me te Marae

He mea nui ngā tikanga whakamātautau taiwhanga me ngā tikanga whakamātautau parae pakari hei whakamana i te hototahitanga o ngā rauemi hiri miihini ki ngā wai tukanga. Mā ēnei whakamātautau ka tū pakari ngā rauemi kua whiriwhiria ki te taiao mahi. Ka whakaratohia e te Tikanga Whakamātautau Paerewa ASTM D471 he huarahi hanganga. Tuatahi, ka whakarite ngā tohunga hangarau i ngā tauira whakamātautau paerewa. Ka inehia e rātou ngā inenga tīmatanga, te taumaha, me te pakeke, ka tuhia ēnei hei āhuatanga taketake. Muri iho, ka rumakina e rātou ngā tauira ki roto i te hinu whakamātautau i te pāmahana mahi mōrahi. Ka roa te rumakina o tēnei tauira mō te wā paerewa, i te nuinga o te wā.70 hāora te iti rawa, me te 168 hāora te pai akeKa puritia e rātou te pāmahana i roto i te ±2°C. Whai muri i te rumakina, ka tangohia e ngā tohunga hangarau ngā tauira, ka pania te hinu mata, ā, ka ine i roto i te 30 meneti. Ka tuhia e rātou te huringa rōrahi, te huringa taumaha, me te huringa pakeke. Ko ngā whakamātautau whiriwhiri ko te kaha kume me te roa. Hei whakamutunga, ka whakamāramahia e rātou ngā hua. Kei roto i tēnei ko te tatau i te ōrau pupuhi rōrahi, te aromatawai i te huringa pakeke mā te whakamahi i te ine Shore A, me te aromatawai i te āhua ā-tinana mō te ngatata, te ngawari, te piri rānei.

Kei reira anō tētahi atu huarahi whakamātautau parae māmā. E hiahiatia ana mō tēnei tikanga kia 3-5 ngā hiri tāpiri o ia rauemi, kia 500ml pea te iti rawa o te hinu pēhi, he pūtake wera me te whakahaere pāmahana (ouma, pereti wera rānei), he ipu karāhe me ngā taupoki, he calipers, he micrometer rānei, me te whakamātautau pakeke o Shore A. Kei roto i te tukanga te ine me te tuhi i ngā rahinga me te pakeke o te hiri tuatahi. Kātahi ka rumakina e ngā tohunga hangarau ngā hiri ki roto i te hinu wera mō ngā hāora 168 (kotahi wiki). Whai muri i te tangohanga, ka horoia kia maroke ngā hiri, ā, ka ine tonu i ngā rahinga me te pakeke. Ka tatauhia e rātou te ōrau huringa. Ko ngā paearu whakaae ko te pupuhi rōrahi iti iho i te 10%, te ngaronga pakeke iti iho i te 10 Shore A, ā, kāore he pakaru e kitea ana, he piri, he ngawari rawa rānei.

Kua whakawhanakehia e System Seals ngā tikanga hou mō te whakamātautau hototahi rauemi-wai. Kei roto i ēnei tikanga ngā paerewa me te wheako whānui o te tono. E toru ngā wāhanga matua o tā rātou whakamātautau hototahi: ngā huringa o ngā āhuatanga miihini taketake, ngā huringa o ngā āhuatanga wera, me te mahi e hangai ana ki te tono. Hei whakarite i te mākū katoa o te wai me te whakateretere i te koroheketanga, ka whakamahia ngā tawhā wā me te pāmahana motuhake. Ko ngā wai i konatunatua ki te wai, pērā i te glycols, i ngā emulsions rānei, ka whakaatuhia ki ngā pāmahana i raro iho i te 100°C. Ko ngā wai e hangai ana ki te hinu ka kite i ngā pāmahana i runga ake i te 100°C. Ka whakahaerehia te whakamātautau mō2,016 hāora (12 wiki)kia tino mākū te katoa. Ko ngā tawhā whakamātautau turanga ko te pupuhi rōrahi, ngā huringa papatipu me te mātotoru, te pakeke, te kaha kume, te roa, te modulus 100 ōrau, te mahi mahi (te horahanga i raro i te pihi kume tae atu ki te 20 ōrau), te huinga pēhitanga, me te ātete ki te pakū. Ko te pupuhi rōrahi e tohu ana i te mimiti wai; he uaua ake te whakaheke, ka whakaiti i te kaha hiri. Ko ētahi atu āhuatanga pēnei i te rōrahi, te matotoru, me te mātotoru ka aroturukitia hei aromatawai i ngā huringa āhua mai i te koroheketanga matū. Ko ngā huringa āhuatanga miihini e aroturukitia ana ko te pakeke, te modulus kume, te modulus 100-ōrau, te kaha kume, me te roa i te whati. Ko te kaupapa matua ko te aromatawai i te kaha o te elastomer ki te mahi hei hiri i roto i tana tono e tika ana ina whakaatuhia ki te wai mahi. Me mahi te whakamātautau tono i muri i te whakatūnga o te hototahi matua. Kei roto i tēnei ko ngā tawhā hei whakatere i ngā pānga o te pēhanga, te pāmahana, te mutunga o te mata, me te nekehanga (whakahoki, hurihuri, hurihuri).

E whakaatu ana ngā paerewa whakamātautau o nāianei i ngā rerekētanga nui. Ko te ASTM D2000 e whakamahi ana i te wā whakaaturanga mōrahi o te 70 hāora, e whakawhāiti ana i ngā āheinga matapae mō te wā roa. Ko te ASTM D4289, mō ngā hinu motuka, e taunaki ana i te maha iti o ngā huringa āhuatanga hei aromatawai. Kei roto i te ASTM D6546 ētahi atu aromatawai āhuatanga, pērā i te mahi mahi me te huinga kōpeketanga, engari e whakawhāiti ana i te roa o te whakamātautau ki te 1,000 hāora. I whakaatuhia e ngā whakamātautau taiwhanga a System Seals ko ētahi huinga wai-rauemi e hototahi ana i te 1,000 hāora kua kore e hototahi i muri i te 2,000 hāora. He maha ngā taunakitanga whakamātautau kāore he aratohu kua whakapumautia mō ngā tono tūmau, hihiri rānei. Ko te nuinga o ngā paerewa whakamātautau kāore e whakauru i ngā huringa o te pāmahana whakawhiti, he mea nui mō ngā tono pāmahana iti. He āputa nui tēnei i roto i ngā tikanga whakamātautau o mua.

Te Aromatawai i ngā Āhuatanga Whakahaere (Pāmahana, Pēhanga, Tere)

He nui te pānga o ngā pāmahana me ngā pēhanga whakahaere tino nui ki te kōwhiringa o ngā rauemi Hiri Mīhini mō te hototahitanga wai. Ka taea e ngā pāmahana teitei te whakangaro i ngā wāhanga elastomeric. Hei tauira, ka pirau, ka turuturu hoki ngā wāhanga ethylene propylene ki tua atu i te...300° Fahrenheit (150° C). Ka puta hoki i ngā pāmahana teitei te kōkō o ētahi warowaihā. Ka ārai tēnei i te nekehanga noa o ngā wāhanga hiri ā-mīhini. Ka taea e ngā wai tukanga te mimiti puta noa i ngā mata hiri, ka puta he tukunga rere. Hei whakatika i ēnei wero, ko ngā kōwhiringa rauemi ko ngā elastomerics i hangaia mō ngā warowaihā motuhake, ngā pāmahana, me ngā wai horoi. Kua hangaia ngā mata hiri kia pakari me te hototahi ki ngā wai tukanga. Hei tauira ko te waro, te kowiri tira, te uku, te tungsten, te silicon, te graphite, me te nickel. Ka whakamahia ngā koranu whakawhanui iti mō ngā wāhanga hiri whakarewa hei whakaiti i te whakawhanuitanga wera e whakararu ana i te mahi hiri. Ko Inconel me Hastelloy te mea e pai ake ana mō ō rātou āhuatanga wera tino pai. Ka tu atu rātou ki ngā taumata teitei me te kore e whakararu i te hanganga. He pai ake te Inconel i te roa, e tu atu ana i ngā pāmahana.neke atu i te 1,000°C. Nā tēnei ka tino hiahiatia i roto i ngā ahumahi rererangi me te tukatuka matū. Ka whakararu te pāmahana tino nui i ngā rauemi hiri, ka pirau, ka pakaru rānei. Ka whakaitihia ngā āhuatanga miihini, ā, ka pakaru te hiri. Ka whakanuia ake tēnei e te huringa wera mā te whakaputa i te ngenge o ngā rauemi.

Ko ngā rerekētanga pēhanga e hiahiatia ana he hiri pakari ake. Mā tēnei ka ārai i te turuturu i roto i ngā taiao pēhanga teitei. He maha ngā wā ka whakamahia ngā hiri mata miihini mō ngā pūnaha pēhanga teitei. Ka āwhina hoki ngā hiri puna-whakakaha ki te ārai i te turuturu. He mea nui tonu te hototahi matū hei ārai i te pirau rauemi me ngā tūponotanga taiao. Mā tēnei ka kore te hiri e pakaru, e pakaru rānei i te pānga matū. Ko ngā elastomers pēnei i a Viton, EPDM, me te Nitrile ka whiriwhiria i runga i tō rātou ātete ki ngā matū me ngā wai motuhake. He tino ātete a Viton ki ngā hinu me ngā wahie, he pai mō ngā tono motuka, ā, ko te nuinga o te wā ka roa te roa o te ora i roto i te pānga warowaihā. Ka ātete te EPDM ki te wai me te mamaoa, he pai mō ngā pūnaha HVAC. He pai te ātete o te Nitrile ki te pakū engari ka pakaru pea ina pā ki te ozone. Ka whakaputa hoki ngā tere mahi teitei i te wera, ka whai wāhi atu ki ngā whakaaro wera mō te kōwhiringa rauemi.
