Me āhua pērā pea ngā pouaka hononga mō ngā mārama huarahi ki ngā mea katoa e pā ana. Whakarerehua ngā ua nui, te parurenga o te tioata huarahi, te one, ngā parapara e pakaru ana, ā, anō hoki ko ngā wero wero e neke haere ana i waenganui i te -30°C ki te 50°C. Nō reira me te iti rawa o te rākau IP67. He aha tēnā? Ko te tikanga, kua tiakina tōtō ia i ngā pūpahi, ā, e taea ana te noho i raro i te wai, e kīia ana he mete tahi te rōrahi, mō te haurua haora kāore ai e marara. Me tino whiwhi tēnei momo tiaki mēnā e hiahia ana mātou kia mahi tonu ngā mārama huarahi ahakoa ngā aha e tuku mai nei te takotoranga.
| Whakarāpopoto | Whakamaru Hukapapa | Tiaki i te Wai | Tōaitanga Rātene Huarahi |
|---|---|---|---|
| IP54 | Āhuatia | Pikotanga | Kāore he pai mō ngā rohe pouri |
| IP65 | Katoa | Ngā pūtau tōkau iti | Mōrearea i ngā riri hau nui |
| IP67 | Katoa | Whakaurunga poto | Tino pai mō te nuinga o ngā whakaurunga |
| IP68 | Katoa | Whakaurunga marino | Hāngia i runga ake i ngā huarahi arataki |
Ko ngā hapūpaku e whakamahi ana i ngā pouaka tiwhikete IP67 e ripene ana i te itinga o ngā wāhi pā ki te āhuarangi i te 60% i te iti ake i ērā me ngā tauira IP65. Ināianei, ko tēnei rāwekenga koreihana e kore e tino nui ana—engari he mea matua herekenga mō te haumātaotao o te iwi me te manawaroa o ngā tikanga amokura.
Ko te whiwhi i te tiwhikete IP67 pono e manaakitia ana ngā paerewa ā-ao kua warewaretia e te nuinga o ngā kaihanga. E here ana te paerewa IEC 60529 i ngā taputapu ki te tino kaukau i raro i te wai mō te haurua haora ki te taha kotahi mita, i te wā e pupuri ana i ngā parawhara totohu katoa. Ki te Amerika ki te Raki, he ōrite ngā whakaritenga wai me te tiaki i te puehu o UL 50E engari heke ana anō i ngā whakamātautau atu mō te ara e arotake ai ngā hua i ngā panoni tūpono o te wera, me te exposure ki te arataki ultraviolet. Ka haere ake anō ngā tikanga o Rāwhiti ka whakauru i EN 60529 e here ana i ngā taputapu kia taea ngā taraweti i te wā o ngā whakamātautau. Ina koa te tiwhikete ake, ko ia wāhanga e tata ana, tae atu ki ērā karu pīrau, ngā tikanga horoi, me ngā hononga i waenganui i ngā wāhanga rerekē o te takotoranga. Me whakamātauria ēnei i ngā tikanga e āhua ana ki ngā ahuatanga kei te mara. Ehara i te mea anō he kape kua toro atu, kāore he tikanga kia mau tonu te kounga i te whanaketanga maha. Ko ngā tirohanga mara kia otinga tonu i te rohe hanga he mea matua hei whakauru mēnā e hiahia ana ngā kamupene kia taea e ō rātou hua te tutuki i ēnei paerewa herekau i te wā.
Kia whakapae koe ki ngā tohu mōhio e tino ngohe ana i ngā wāhanga matua:
Ko ētahi kaihanga e tohu ana mā rātou anō mā ngā tautuhinga whare e kore nei e tika, ka pakaru i ngā here o IEC 60529 §14.2.3. Me tono ake katoa ngā ripihana takotoranga me ngā nama tūtohi tētē o ngā kīrea kua whakamātia. Mō ngā tāpuranga matua, whakamahia ngā kāri tohu mātaitai ki roto i ngā pouaka kia whakapumautia te kounga roa-tere.
Ko te mahi IP67 e tikangia ana e te tāpapa tika. Ko ngā pehi silicone, ēnei rānei EPDM e nui ake ai te manawaroa ki ngā āhuarangi ina tāpiripiri tā rātou. He wāhanga matua ēnei:
Ko te whakamahi i te torque tōpū e aki ai ngā rere me te roa o te wā o te whakamahi, ā, ina heke pōturi ake ngā āhuatanga o te rangi.
Ko te whiriwhiri i te matātoko tika e pa ana ki te roa o te wā o te whakamahi me te tiaki:
| Āhuatanga | Ko te Parika Parika | Polycarbonate Kua Whakarereketia |
|---|---|---|
| Te aukati i te koroheketanga | Meiha te kōtaha pūrau | Tūmatanui kore māhu |
| Whakahaere Hāora | Whakaputangia hihiri pai ake (≈15°C te whakaiti) | Meiha hoahoa whakamaikai pāpori |
| Mango whiuwhiu | 8–10 Jōnia (IK09 te tātai) | 4–6 Jōnia (IK07 te tātai) |
| Ko te māhu o te ao | Kāore he mea māhu i te kōtaha | 0.02% te māhu tau ki ngā kaiwhakarere i te wā |
He pai te paraihe mō ngā rohe tai, āpiti rānei, ā, ko te polikarbonat e 40% te māmauranga taumaha, me te whakauru ai ka māmā ake. Me whakauru anō ngā whakamātautau paraihe tai e IEC 60068-2-52 mō ngā whakaurunga kei roto i te 500 mita mai i te tai.
Ka nui ake te māmā o te whānuitanga o te huinga ki ngā pouaka pātui āhuatanga nā rātou ngā rāranga tāpiri e taea ana te tango me ngā wā kowhiritia mō te kabel. Ka nui te āwhina o ngā rangahau kabel IP67 e manawataki ana i te mahi tiaki, nā te mea ka pupuri tō rātou i ngā kabel kia pūmau kia kaua ai e tāwhai kia tango. Kua kitea i ngā tātai paraoa e kore ana e huringa hapa i te whakauru i te whakauru i te hautoru ina whakarerekītia ki ngā pouaka tūtohi tawhito ina hāngai ana ki ngā rāranga tohu mua me ngā wāhi hono ake. He mea nui te āhua o ēnei hoahoa ki ngā kaupapa tāone mātātoko trū tētahi hononga mō ngā kaiwhakamātau motuhake, ka pupuri i ngā kabel katoa ki roto kia māmā ai te urupare mō ngā kaihautū e mahi ana ki te pūnaha i muri ake nei.
Hāngiaia ki te whakaeke ki ngā tikanga pārearea, ka taea e ēnei pouaka te tino whakaeke ki ngā panonitanga o te wera i ētahi atu taputapu. Ānō te ripoata mai e ngā kaimahi tiaki tāone, ko ngā pūkenga motuhake e kīato ana i ngā ririwhiwhi e āki ai te pānga ki te warewarenga o ngā wāhi i te tāone. He pai te mahi a ngā tauira paraihe i karapaina ki te makariri ina hea te wāhi e nui ai te wehenga wera, ā, ko ngā mea i hangaia ki te paraihe kaha ake pea ki te takotoranga o te tai i te taha moana. Anō hoki, he ātaahua te āhua, e kore e tino tā te hunga ki te titiro, ā, ko ngā totohu pērā i ngā totohu pēnei e kore e pai ana te whakamātau mēnā e ngana ana koe ki te uru atu kāore i te whakaaetia.
Ko ēnei kōpae e whakauru ana i ngā aitua hiko tīkapa me ngā pūtaka hiko hei tango i te hiko mai i ngā kaiwhakahaere LED kia kaua e pakaru te aukatitanga o te wai. Ko ngā ara hiko māmā e pupuri ana i te mana IP67 i te wa e heke ai ngā tikanga pakaru kaiwhakahaere 28%. Ko ngā wāhi puipui paerewa e āwhina ana i ngā momo kaiwhakahaere rerekē, ā, ko ngā komiti takotoria e aki ai te whakangāhau hiko-iraumatiu i waenganui i ngā ara hiko-teitei me ngā ara whakahaere.
Ina tāpiri ana i ngā rīpene kawhe, me āki ake i ngā tikanga IP67 ā, me whakapau kia tika te rahi o te kawhe me te matū o te takotoranga. Mēnā he hapa tēnei ka hua ai te wāhi noho, nō reira ka pakaru te rīpene ki te kawhe. Mō te pātu ki ngā tikanga kino, ko ngā taputapu EPDM, nō reira ko ngā taputapu silicone e mahi pai ana nā reira e taea ai te tautoko i ngā wāhi tino makariri, mai i te 40 negatia Celsius ki te 120 positia. Me arataki ki ngā kōrero a te kaihanga mō te kaha pakaru, e 15 ki te 20 Nm (Newton meters) mō ngā rīpene M20 engari me whakamahi i ngā taputapu tika hei ine. Ki te tino taumaha te pakanga ka pakaru pea te pānga pātui, ā, ki te iti rawa ka waiho wāhi mā te wai kia uru mai. Kaua hoki e wareware ki te aha o ngā matū i te wā. Ka pākiki ngā waeonga paraihe i muri i te tau o te tū i te rā, ā, ka pakaru ngā taputapu paraihe i muri i ngā wāhi tino makariri ki te tino wera. Nō reira he nui te take o te tiaki tūmatanui, ina nui ake i ngā takiwā tata ki te tai moana kei hea ka tere ake te marorihanga e te hau mātukutuku, nō reira i ngā takiwā tāpoi kei hea ngā kirihou e noho ana. Ko tētahi ture pai ko te tirotiro me te whakakapi i ngā taputapu kia kotahi tekau mā ia tau i ēnei takiwā.
Whakamātau ia whāwaru mā te whakamahi i ngā tikanga kore-herenga:
Tuhi i ngā hua tuatahi i te wā o te whakauru. Whakakapi i ngā wāhanga e whakaatu ana i te iti ake i te 15% te ngaro toki, i te āhua kaua e hoki ki te āhua tōna, kia mau ai te tiaki roa-roa.
Ko te reitinga IP67 e tiaki ana i ngā pouaka hononga mai i te pōhutukawa me te taea e wai tētahi wā, nō reira he mea pai mō ngā tikanga taiao kaha e āhua ana ki ngā pūmahara hiko.
Kāore i te tino whakamarie ngā pouaka reitinga iti ake pērā i te IP65 ki ngā wai pouri, engari kāore ki te pararaihe, nō reira he raru kei te wā o ngā pouri marino, ka piki ake te mōrearea o ngā herenga hiko me ngā utu tiaki.
Me tirotiro e ngā tōpuni ngā tohu rākau whakaaetia, ngā korero mō te roa o te whakamātau me te tere pararaihe, me te tono i ngā ripoi takotoranga tūturu me ngā tau tūtohu kia tiakina ai te reitinga tika IP67.
Ko te paraihe kiri tārua e tino pai ana mō ngā rohe taiapa, i te wāhi e tūpono ai te riri, ā, ko te polycarbonate e pā ana te aha ki te aha e tino māma ai te whakakaha me te whakamātau, me te mātau anō i te kiko me te aha ki te aha.
