Ka taea te whakaiti makariri VS Ka taea te whakaiti wera

I tēnei rā ka hiahia ahau ki te whakaatu i te rerekētanga i waenga i te mīhini whakaiti wera me te mīhini whakaiti makariri.

1. Te mātāpono mahi

①Ina tukuna te whakangāwari wera, me iti ake te diameter o roto i tērā o te hua kua oti, kātahi ka whakawhānuihia te diameter o roto ki roto i te hua kua oti, ā, mā te wera e whakahoki mai ki tōna āhua iti ina tukuna. Koinei te mātāpono mahi o te whakangāwari wera.

②He tino māmā te kaupapa o te ngongo whakangūngū makariri. Pērā i te here rapa, ka whakamahia he mowhiti kukume hei tautoko i te kōhao kia nui ake ai. Ka heke te whānui o roto ina tangohia te tautoko i te wā e whakamahia ana.

2. Tikanga whakamahi

①Me whakamahana te ngongo whakaiti wera i te wā e whakamahia ana, ā, me whakamahi i ngā taputapu whakamahana motuhake, pērā i te pū wera ahumahi me te oumu ahumahi, kia matatau ai te kaiwhakahaere.

②Kāore e hiahiatia kia whakatiotia te ngongo whakangūngū makariri i te wā e whakamahia ana, kāore hoki e hiahiatia he taputapu tuatoru. He tino māmā te whakamahi. Me tango noa i te mowhiti tautoko hei tango i te kaha tautoko, ā, ka taea te whakangūngū aunoa.

3. Te whakamahinga matua

①Kua wehea ngā rauemi o te ngongo whakaiti wera ki te PVC, te PE, te PVDF, te Teflon, te rapa fluorine, te rapa silicone me ētahi atu rauemi matua. Ka taea te whiriwhiri i te ngongo whakaiti wera o ngā rauemi rerekē kia rite ki tōna whakamahinga. He nui ake te diameter o roto o te whakatakotoranga, mai i te whakatakotoranga ngongo whakaiti wera iti rawa 0.5mm ki te 200mm. He whānui hoki te whakamahinga o te mara, he maha atu ngā tikanga, ngā taputapu hiko, te rererangi, te motuka me ētahi atu mara ka kore e taea te wehe i te whakamahinga o te ngongo whakaiti wera.

②He māmā noa iho te rauemi o te ngongo whakangūngū makariri, ko te tikanga he EPDM, ā, ko te iti rawa o te whakatakotoranga he 20mm te whānui o roto, nō reira kāore e pai te whakamahinga. He mea whakamahi whānuitia ki ngā wāhi kāore e taea te puta mai ngā pūtake wera, me ngā wāhi kāore e watea ki te whakamahi i ngā taputapu tuatoru, ā, he mea whakamahi whānuitia ki ngā mahi whakawhitiwhiti kōrero me ētahi atu mara.

4. Ko te rerekētanga i waenganui i te ngongo whakaiti wera me te ngongo whakaiti makariri kei runga ake nei, he pai rawa atu, mai i te whakamahinga o te taiao, te tātaritanga raruraru motuhake.

①Mō te ngāwari o te whakamahi, he pai ake te ngongo whakamatao i te ngongo whakamahana, kāore e hiahiatia te whakamahana, me tango noa te mowhiti tautoko.

②He tino pai te mahi ā-wai o te ngongo whakaiti makariri, nā te mea he ātete wai te rauemi, ka taea te taumata ā-wai ki te IP67, ā, ka taea te whakarite ki ngā whakaritenga whakamātautau a te kaiwhakamahi kia eke ki te IP68. Ā, ko te ngongo whakaiti wera anake me te ngongo whakaiti wera piri ka taea te eke ki te taumata IP67.

③Mai i te hunga whakarongo o te mākete, he pai ake te ngongo whakaiti wera i te ngongo whakaiti makariri, nā te mea he nui ake ngā whakatakotoranga o te tauira ngongo whakaiti wera, he pai ake te kōwhiringa.

④Mō te utu, me tino whai hua te ngongo whakaiti wera. He pakari ake te hangarau ngongo whakaiti wera, he iti ake te uaua o te whakaputa, he iti ake te utu o ngā rauemi mata, nō reira he iti ake te utu.
