He aha te Paerewa Hiri Mīhini DIN 24960?

Kupu Whakataki

He paerewa roa te DIN 24960 mō ngā hiri ā-ringa e whakamahia ana i roto i ngā papu tohanga, i hangaia hei whakarite kia taea te matapae i ngā hononga hiri me te papu puta noa i ngā kaihanga. Mā te mārama ki tēnei ka āwhina i te whakamārama he aha i taea ai te whakawhiti i ētahi hiri, he aha te hiranga o ngā āhuatanga tāutanga, me te pehea e paerewahia ai te āhua o te pouaka whakakī papu i roto i te mahi. E whakamārama ana tēnei tuhinga i ngā mea e hipokina ana e te DIN 24960, tae atu ki tōna whānuitanga, ngā whirihoranga hiri noa, me te horopaki whakahaere, kātahi ka whakamārama i tōna hononga ki ngā paerewa Pākehā hou me te aha e puta pinepine ai te tohu i roto i ngā whakatakotoranga hangarau, ngā rarangi pukapuka, me ngā whakataunga whakakapinga.

He aha te DIN 24960, ā, he aha ngā mea e hipokina ana e ia?

Ko te paerewa DIN 24960 he anga hangarau taketake mō te whakahaere wai. I mua koia te whakatakotoranga matua o Tiamana mō ngā rahinga tāutanga me ngā takai whakahaere ongā hiri miihinii roto i ngā papu toriti. I whakawhanakehia e te Deutsches Institut für Normung (DIN), i hangaia tēnei paerewa hei whakataurite i ngā āhuahanga o ngā pouaka whakakī papu me ngā hiri miihini e uru ana ki roto, kia taea ai te whakauru matapae i waenga i ngā taputapu hurihuri me ngā wāhanga hiri.

Ahakoa kua whakakapia e ngā paerewa whānui o Ūropi, kei te mau tonu te DIN 24960 i roto i te whakaingoatanga hangarau ahumahi. E whakatau ana i ngā rohe ā-wāhi me nohoia e te hiri, kia taea ai te whakawhiti i ngā hiri miihini mai i ngā kaihanga rerekē me te kore e hiahiatia he miihini, he whakarerekētanga rānei ki te whare papu.

Te whānuitanga, ngā momo hiri, me ngā kōpaki ā-ahu

Ko te whānuitanga matua o te DIN 24960 ko te tautuhi i ngā kōpaki ā-ahu mō ngā hiri mīhini mahi-kotahi, kore-taurite, me te taurite. Ka whakatūhia e ia ngā ā-whao paerewa i roto i te rūma hiri o te papu, e tohu tika ana i te diameter waho mōrahi o te hiri, te poka e hiahiatia ana mō te pouaka whakakī, me te wāhi tuaka e hiahiatia ana mō te pēhanga puna tika. Ka whakarōpūhia e te paerewa ngā roa hiri ki ngā tohu motuhake, ko te mea nui ko te L1K (roa mahi poto) me te L1N (roa mahi noa). Mā te piri ki ēnei rohe rōrahi tino pakari, ka whakarite ngā kaihanga taputapu kia uru tika ngā hiri wāhanga paerewa ki roto i te whare kua tohua.

Ngā rahi o ngā toki me ngā rahi o te tāutanga

Ko tētahi āhuatanga nui o te DIN 24960 ko tōna whanaketanga pūnaha o ngā rahi o te toki, e ahu mai ana i te 10 mm ki te 100 mm i roto i ngā pikinga paerewa. Mō ia diameter o te toki (d1), ka tohua e te paerewa te poka pouaka whakakī e rite ana (d3), te diameter o waho o te nohoanga (d7), me ngā roa tuaka tika (L1K me te L1N) e hiahiatia ana mō te tāutanga. Mā tēnei ka hangaia he matapae matapae mō ngā kaihangarau i te wā e hoahoa ana i ngā toki papu me ngā rūma hiri.

Mā ēnei herenga ā-ahu ka mau tonu te ōwehenga pēhanga tika o te pane hiri hurihuri me te nohoanga tūmau ina oti katoa te huihui o te papu. Mā tēnei ka ārai i te kakahu nui o te mata mai i te pēhanga nui me te turuturu mai i te kaha o te puna kāore i te rawaka.

Ngā mea kāore i tautuhia e te DIN 24960

Ahakoa he tino motuhake te DIN 24960 mō ngā ine ā-wāhi, he mea nui anō hoki kia mārama ki ngā mea kei waho o tōna whānuitanga. Kāore te paerewa e tohutohu ana i ngā rauemi hanga mō ngā mata hiri, ngā elastomers, te mahi whakarewa rānei. Kāore hoki e whakaurua ngā herenga mahi motuhake, pērā i te pēhanga mōrahi, ngā paepae pāmahana, ngā herenga tere rānei o te pou, ahakoa kua honoa ki ngā hoahoa papu PN16 (16 pae) i ngā wā o mua. Hei tāpiri, kāore te DIN 24960 e tautuhi ana i ngā āhua hiri ā-roto. E wātea ana ngā kaihanga ki te whakamahi i ngā puna kotahi, ngā puna maha, ngā puna ngaru rānei, mena ka uru te huihuinga katoa ki roto i te takai paerewa L1K, L1N rānei.

He aha te Hiranga Tonu o te DIN 24960

Ahakoa kua whakakapia manatia e ngā paerewa Pākehā, kei te whakamahia tonutia te tohu DIN 24960 i roto i ngā mahi hokohoko, tiaki, me te hangarau whare. Ko tōna hiranga pumau e hono ana ki te turanga nui o ngā taputapu tawhito kua tāutahia me te whakawhirinaki o te mekameka tuku taonga o te ao ki ngā whakarāpopototanga ā-ahu kua whakapumautia, kua mārama whānuitia.

Me pēhea te whakapai ake i te whakawhitiwhiti

Ko te uara matua o te DIN 24960 kei roto i tōna kaha ki te whakahaere i te whakawhitiwhitinga o ngā wāhanga. I roto i ngā tipu ahumahi e whakamahi ana i ngā rau o ngā papu tohanga, mā te whakarite i ngā hiri e tutuki ana ki te DIN 24960 ka taea aingā tari tiakiki te kimi i ngā wāhanga whakakapinga mai i ngā kaihoko maha me te kore e mataku kei rerekē ngā āhuatanga. Mā tēnei whakawhitiwhiti ka taea te hoko i ngā hiri wāhanga paerewa, ka whakatairanga i te utu whakataetae me te whakaiti i ngā arai mekameka tuku. He maha ngā wā ka ripoatahia e ngā whare e neke ana ki ngā āhuatanga DIN paerewa he whakahekenga i roto i ngā SKU o te rarangi hiri miihini mā te 30% ki te 40%, nā te mea ka taea e te hoahoa hiri kotahi te mahi ki ngā tauira papu maha puta noa i te tipu.

Te wāhi e whakahuatia tonutia ana te paerewa

Kei te whakamahia whānuitia tonutia te DIN 24960 mengā papu matū paerewa, inā koa ko ērā i hangaia kia rite ki ngā whakaritenga ISO 2858 me te DIN 24256. Ko ēnei papu, i hangaia mō te pēhanga ingoa o te 16 pae, he rūma hiri i hangaia kia whakaaetia ngā hiri DIN 24960. I tua atu i Ūropi, he maha ngā kaihanga i Āhia me Amerika e whakamahi ana i te "paerewa DIN" hei whakaahuatanga hokohoko me te hangarau hei whakapumau i ngā kaihoko ki te hototahi ki ngā taputapu hurihuri i hangaia e te ine. Nō reira, ko ngā tuhi hangarau, ngā pepa raraunga papu, me ngā pukapuka ā-ringa OEM puta noa i te ao kei te haere tonu ki te whakapūmau i te DIN 24960 hei whakapumau i te hototahitanga hanganga.

Te Whakataurite o te DIN 24960 ki te EN 12756

I te mutunga o te tekau tau atu i 1990, i whakaurua e te Komiti Paerewa o Ūropi (CEN) te EN 12756 hei whakakotahi i ngā paerewa hiri miihini puta noa i ngā whenua mema o Ūropi. I whai hua tēnei paerewa i te DIN 24960, ko te tikanga he hononga nui ngā mea e rua, ahakoa he rerekētanga nui kei roto i tā rātou tono me te whakaingoa.

Ngā rerekētanga matua me ngā āhuatanga ōrite

Ko te EN 12756 te putanga hou, puta noa i te ao Pākehā o te DIN 24960. Ko ngā āhuatanga ā-tinana—tae atu ki ngā roa mahi L1K me L1N matua, ngā pikinga o te rakau d1, me ngā diameter nohoanga d7—ka noho ōrite tonu i waenga i ngā paerewa e rua. Ka uru te hiri i hangaia ki te DIN 24960 ki roto i tētahi kōhao i hangaia mō te EN 12756, me te ritenga kē.

He aha te tutuki i ngā āhuatanga kāore e tino hototahi

Ahakoa e whakamanahia ana e te DIN 24960 me te EN 12756 ka uru te hiri ki roto i tētahi wāhi kua tohua, kāore te tutuki i ngā āhuatanga e rite ana ki te hototahitanga mahi. Tērā pea he rerekē rawa ngā tere puna, ngā huinga pēhanga elastomer, ngā rohenga Tere-Pēhanga (PV) rānei o ngā hiri e rua e tutuki ana i ngā paerewa mai i ngā kaihanga rerekē. Hei tauira, ka whakamahia pea e tētahi hiri e tutuki ana i te DIN tētahi huinga rauemi me te rohenga PV o te 20 MPa·m/s, ko tētahi atu ka eke ki te 50 MPa·m/s. Mēnā ka whakawhitihia ēnei hiri e tētahi tīma hoko i runga i te taunga āhuatanga anake, ka tere te hekenga o te wera o te hiri iti iho te whakatauranga, ka pakaru wawe hoki ina tukuna ki ngā wai matotoru teitei, ki ngā tere rakau teitei rānei.

Āhea te whiriwhiri i ngā hiri paerewa

Ko ngā hiri paerewa e tutuki ana i te DIN 24960, i te EN 12756 rānei te kōwhiringa tino pai mō te 80% o ngā tono whānui, tae atu kite maimoatanga wai, te whakawhiti matū ngawari, me te tukatuka hauwaiwai iti-pēhanga. Me tohu e ngā miihini ēnei wāhanga paerewa ina taka ngā āhuatanga mahi ki roto i ngā tawhā taurite (i raro iho i te 16 pae me raro iho i te 150°C) ā, ko te whakaiti i te utu katoa o te mana pupuri mā te whakakotahi i ngā taonga te whāinga matua. I tetahi atu taha, mō ngā wai tino paitini, whakakoi, pāmahana tino nui rānei, he mea hanga-ritengā hiri kāteretihe maha ngā wā ka whakakapi i ngā hiri wāhanga paerewa.

Me pēhea te whakamahi i te DIN 24960 i roto i te Hokonga me te Tiaki

Ko te hoko me te pupuri i ngā hiri miihini i raro i te paerewa DIN 24960 me whai mana whakahaere kounga pakari me ngā tikanga manatoko tika. Nā te mea ko ngā ine anake te mea e whakahauhia ana e te paerewa, ko te kawenga ko te hoko me te hangarau tiaki hei whakamana i te kounga o ngā rauemi me ngā manawanui hanga tika.

Me pēhea te manatoko i te tutuki i ngā whakaritenga

Ko te manatoko i te tutuki i te DIN 24960 me tirotiro i ngā āhuatanga i te taenga mai o ngā wāhanga. Me whakamahi ngā tohunga tiaki i ngā maikoromita me ngā calipers kua whakatikatikaina hei ine i ngā āhuatanga matua: te diameter o roto o te huihuinga hurihuri, te diameter o waho o te nohoanga tūmau (d7), me te roa tuaka kāore i kōpeketia. Me whakataurite ēnei inenga ki ngā manawanui e whakaaetia ana e te paerewa. Hei tāpiri, he mea nui te manatoko i te roa tāutanga tika (L1K, L1N rānei) i te wā huihuinga. I te nuinga o te wā ka tuhia e ngā tohunga te pou hei whakarite kia kōpeketia te hiri ki te mirimita tika kua tohua e te paerewa, kia kore ai e puta he hapa uta mata kino.

Ngā mōrearea noa mō te hoko me te kounga

Ko te mōrearea pūtake e pā ana ki ngā hiri DIN 24960 ko te rerenga mai o ngā hiri hokohoko iti te utu, kāore e tutuki ana i ngā whakaritenga. Ahakoa he rite tonu ēnei hiri ki ngā rahinga whānui o te paerewa, he maha tonu ngā wā ka pāngia e te ngoikore o ngā manawanui moroiti. Ko te papatahi o te mata he iti iho i te paerewa te take matua o te turuturu; me herea ngā mata hiri kounga teitei ki te papatahi o te 2 ki te 3 ngā whitiki rama helium (tata ki te 0.6 ki te 0.9 µm). Hei tāpiri, ko ngā elastomer rūpahu, iti rānei te kounga, ka whakaatu pea i te pakeke o te takutai, ka arahi ki te whakaputanga i raro i te pēhanga, ki te kore rānei e whakarato i te hiri tuarua e tika ana. Me arotake e te hunga hoko ngā kaiwhakarato kia whakarite kia rite te whakarewa me ngā elastomer ki ngā whakaritenga hototahi matū o te wai kua papuhia.

Ngā tuhinga me ngā manawanui e hiahiatia ana

Hei whakaiti i ngā mōrearea whakahaere, me whai tuhinga motuhake ngā ota hoko mō ngā hiri DIN 24960, tae atu ki ngā tiwhikete whakamātautau rauemi EN 10204 3.1 mō ngā wāhanga whakarewa me te whai i ngā puranga mō ngā elastomers. E whakawhirinaki ana te paerewa ki ngā ātete mīhini pakari i roto i te whare papu. Ko te poka pouaka whakakī me whai ātete H8, ko te rakau papu me mīhini ki te ātete h6, h8 rānei. Hei tāpiri, me pupuri te mata o te rakau kei reira te mowhiti-O hihiri ki te taratara mōrahi o Ra 1.6 µm hei ārai i te kakahu taratara i runga i te elastomer i ngā nekehanga tuaka moroiti.

Me pēhea te whakatau i te wā e whakamahia ai te DIN 24960

He whakatau nui te whakatau mēnā me tohu he hiri wāhanga DIN 24960, me whiriwhiri rānei i tētahi hiri kātere hangarau, e pā ana ki ngā inenga pono o tētahi whare me te tahua tiaki. Me whakataurite tēnei whakatau i ngā utu o mua, te uauatanga o te tāutanga, me te pumau o te mahi mō te wā roa.

Ngā paearu whakatau mō te hangarau me te hokohoko

Me arotake e ngā tīma hangarau me ngā tīma hoko ngā āhuatanga waipēhi me te taiao motuhake o te papu. Ko ngā hiri kore taurite o te DIN 24960 e herea ana ki ngā pēhanga i raro i te 16 pae, ko ngā putanga taurite e rite ana ki ngā whāriki ā-ahu kotahi ka taea te mahi tae atu ki te 25 pae. Ko ngā rohe pāmahana e whakatauhia ana e ngā elastomers kua whiriwhiria, mai i te -20°C ki te 200°C mō ngā matū paerewa FKM, EPDM rānei. Mena ka nui ake te tono i ēnei paepae, mena he matū matū waro morearea (VOC) te wai e hiahia ana ki te tutuki i te API 682 me ngā whakaritenga hiri-rua, kāore e ranea ngā hiri wāhanga paerewa DIN 24960, ā, me whakamahi i ngā pūnaha hiri motuhake, pakari ake.

Me pēhea te whakataurite i te paerewa, te rarangi taonga, me te mahi

Ko te whakataurite i te paerewa me te mahi me whai tātaritanga Utu Katoa o te Mana Pupuri (TCO). Ko te utu mō ngā hiri wāhanga paerewa DIN 24960 he 40% ki te 60% te iti iho i te utu i mua i te hiri kātere kua oti te huihui. Heoi, me whakahaere tika ngā hiri wāhanga me te kaimahi tino pūkenga kia tika ai te tāutanga, ā, e 2 ki te 4 hāora te roa o te tāutanga hei whakarite kia tika te whakatakotoranga o te roa mahi me te ārai i te poke o te mata. Ngā whare me ngā kaimahi tino whakangunguangā rōpū tiakiā, ko te whakahau kia iti ngā utu o ngā rawa ka tino whai hua mai i te whakapūmau i te DIN 24960. I tua atu, ko ngā tipu e pāngia ana e te nui o te huringa mahi, ko te hunga rānei e aro nui ana ki te tere o te wā-ki-te-whakatika (MTTR) ka kitea pea kua ea te utu tīmatanga teitei o ngā hiri kātereti e tā rātou tāutanga mono-ā-ringa, ka kore ai e whai pānga ngā herenga ā-rahi o te DIN 24960 ki tā rātou tauira whakahaere.
