He tohunga a ZFA Valve ki te hanga i ngā momo takirere pūrerehua katoa. Mena he hiahia ā ngā kiritaki, ka taea e mātou te hoko i te actuator hiko o ngā waitohu o te ao, o ngā waitohu rongonui rānei o Haina mō mātou, ā, ka tukuna atu ki ngā kiritaki i muri i te angitu o te patuiro.
An takirere pūrerehua hikohe takirere e whakahaerehia ana e te motuka hiko, ā, e whakamahia ana hei whakahaere i te rere o te wai, o te hau rānei. I te nuinga o te wā he takirere pūrerehua, he motuka, he taputapu tuku me te pūnaha whakahaere.
Ko te kaupapa mahi o te takirere pūrerehua hiko he pana i te taputapu tuku i roto i te motuka hei huri i te pereti takirere, kia huri ai te horahanga o te wai i roto i te tinana takirere me te whakatikatika i te tere rere. Ko ngā āhuatanga o te takirere pūrerehua hiko he tere te whakatuwhera me te kati, he ngāwari te hanganga, he iti te rahi, he māmā te taumaha, ā, he penapena pūngao.
1. Te ariā o ngā momo motuka ātete-wai me te ātete-pahūtanga
Ko te taumata mōtini ātete-wai e pā ana ki te pēhanga wai me ngā taumata hohonu o te wai ka taea e te mōtini te tu atu i raro i ngā āhuatanga ātete-wai rerekē. Ko te whakarōpūtanga o ngā taumata mōtini ātete-wai kia tutuki ai ngā taiao whakamahinga rerekē me ngā hiahia kia mau tonu ai te mahi me te roa o te mahi a te mōtini. Ko te whakatauranga mōtini ātete-pahū e pā ana ki te kaha o te mōtini ki te karo i te pahūtanga ina mahi ana i roto i te taiao morearea.
2. Te whakarōpūtanga o ngā momo motuka ātete wai
1. IPX0: Kāore he taumata tiaki, ā, kāore he mahi ātete wai.
2. IPX1: Ko te taumata tiaki he momo maturuturu. Ina maturuturu te wai o te motuka i te taha poutū, e kore e kino ki te motuka.
3. IPX2: Ko te taumata tiaki he momo maturuturu whakarara. Ina maturuturu te wai o te motuka i te koki o te 15 nekehanga, e kore e kino ki te motuka.
4. IPX3: Ko te taumata parenga he momo wai ua. Ina tauhiuhia te motuka e te wai ua ki tētahi taha, e kore e pakaru te motuka.
5. IPX4: Ko te taumata parenga he momo rehu wai. Ina rehuhia te motuka ki te wai mai i tētahi taha, e kore e kino ki te motuka.
6. IPX5: Ko te taumata parenga he momo rehu wai kaha. E kore te motuka e pakaru ina pāngia e te rehu wai kaha ki tētahi taha.
7. IPX6: Ko te taumata parenga he momo rere wai kaha. Kāore te motuka e pakaru ina pāngia e te rere wai kaha i tētahi taha.
8. IPX7: He momo rumaki poto te taumata tiaki. Kāore te motuka e pakaru ina rumakina ki te wai mō te wā poto.
9. IPX8: He momo parenga mō te wā roa. Kāore te motuka e pakaru ina roa te wā e rumakina ana ki te wai.
3. Te whakarōpūtanga o ngā momo motuka ātete-pahū
1. Taumata ātete-pahūtanga Exd: Ka whakahaerehia ngā motuka taumata-Exd i roto i tētahi anga ātete-pahūtanga hiri hei ārai i ngā pahūtanga i puta mai i ngā mura ahi, i ngā pewa rānei i roto i te motuka. He pai tēnei motuka mō te whakamahi i roto i ngā taiao hau mura, i ngā taiao mamaoa rānei.
2. Paerewa ātete-pahū Exe: Ka karapotia e ngā motuka paerewa Exe ngā pito o te motuka me ngā hononga taura ki roto i tētahi ārai-pahū hei ārai i te mawhiti o ngā mura ahi, o ngā pewa rānei. He pai tēnei motuka mō te whakamahi i roto i ngā taiao he kohu mura.
3. Taumata ātete-pahūtanga Ex n: Kei roto i te anga ngā wāhanga hiko ātete-pahūtanga o ngā motuka taumata Exn hei whakaiti i te whakaputanga o ngā mura me ngā pewa. He pai tēnei motuka mō te whakamahi i roto i ngā taiao hau mura, i ngā taiao mamaoa rānei.
4. Taumata ātete-pahūtanga: Kei roto i te anga o ngā motuka taumata-pahūtanga ngā wāhanga hiko ātete-pahūtanga hei tiaki i ngā wāhanga hiko o roto i te motuka mai i ngā hau mura, i te mamaoa rānei. He pai tēnei momo motuka mō te whakamahi i roto i ngā taiao kei reira ngā hau mura, ngā kohu rānei.
4. Ngā āhuatanga o ngā momo motuka ātete-wai me te ātete-pahūtanga
1. Ko te teitei ake o te taumata o te motuka ātete-wai me te ātete-pahū, ko te pai ake o te mahi ātete-wai me te ātete-pahū o te motuka, ko te nui ake o te pēhanga wai me te hohonutanga wai ka taea e ia te tu atu, ā, ko te nui ake o tana mahi ātete-mōrearea.
2. Mā te whakapai ake i te taumata o te motuka ātete-wai me te ātete-pahū ka piki ake te utu o te motuka, engari ka taea te whakapai ake i te roa o te ratonga me te pono o te motuka.
3. Ko te kōwhiringa o te momo motuka ā-wai me te ātete-pahū me hangai ki te taiao whakamahinga tuturu me te hiahia kia mau tonu te mahi me te roa o te ratonga o te motuka.
I roto i te poto, he mea nui te taumata ātete-wai me te ātete-pahū o te motuka hei whakarite i te haumaru. He rerekē ngā taumata e tika ana mō ngā taiao morearea rerekē, ā, me tino whai i ngā paerewa me ngā ture haumaru e tika ana.
I roto i te poto, he mea nui te taumata ātete-wai me te ātete-pahū o te motuka hei whakarite i te haumaru. He rerekē ngā taumata e tika ana mō ngā taiao morearea rerekē, ā, me tino whai i ngā paerewa me ngā ture haumaru e tika ana.
