1. Mita Wai Pūrere Kotahi
Whakamāramatanga
Ko te mita wai kotahi-pūwero he momo mita wai nekehanga pai, he māmā noa iho te hanganga. Ka whakamahia he pūwero wai kotahi, he kukū hei akiaki i te impeller kia huri, ā, ka tatau i te wai e pau ana mā te huri i te tere hurihuri o te impeller hei rere whakaemi mā roto i tētahi tikanga tuku. He mea hanga matua mō te ine i te rere o ngā paipa iti te whānui.
Kaupapa Mahi
Ina rere te wai ki roto i te tinana mita, ka arahina e te taputapu arataki rere hei hanga i tētahi rerenga tere-tere kotahi, ka pā ki ngā mata o te impeller. Ka huri te impeller i te tere e rite ana ki te tere rere o te wai. Ka tukuna te hurihanga ki te pūnaha tatau mā roto i ngā taputapu, ā, ka whakaaturia te rōrahi wai kua kohia ki runga i te mata hei pānui mā ngā kaiwhakamahi.
Ngā Āhuatanga Matua
- Hanganga Māmā, Utu-Whai Hua: He iti ake ngā wāhanga o roto, he iti te utu hanga, he ngāwari ki te whakaputa me te huihui, me te utu whakataetae mō ngā hoko nui.
- Rahi Kiato me te Tāutanga Māmā: He iti te rahinga, he māmā te taumaha, he pai mō te hononga miro (te nuinga DN15 – DN25), ā, he watea mō te tāutanga ki ngā wāhi whaiti pēnei i ngā kīhini me ngā kaukau noho.
- Mahi Pūmau mō te Rere Iti: He tino aro ki ngā tere rere iti, he ine tika mō te whakamahinga wai o ia rā, me te tere rere tīmatanga iti.
- Ngā Here: He iti te ātete ki ngā poke wai; he ngāwari te pakaru o te impeller, te ārai rānei i te wā e ine ana i te wai me te nui o te paru. Kāore e pai mō ngā āhuatanga rere nui, pēhanga nui rānei.
Ngā horopaki tono noa
Ngā whare noho, ngā whare noho iti, ngā toa arumoni iti (pērā i ngā toa hokomaha, ngā wharekai iti), me ētahi atu wā he iti te wai e whakamahia ana, he iti hoki te tere o te rere.
2. Mita Wai Maha-Jet
Whakamāramatanga
He putanga whakapai ake te mita wai maha-pūngao o te mita wai kotahi-pūngao. He hanganga whakauru wai maha-ira tōna, e wehewehe ana i te wai e tomo mai ana kia maha ngā pūngao rere ōrite hei akiaki i te impeller kia huri. Ka whakataurite i te kaha rere wai i runga i te impeller, kia pai ake ai te tika me te pumau o te ine, inā koa mō ngā awhe rere waenga.
Kaupapa Mahi
Ka uru te wai ki te tinana mita, ā, ka tohatoha ōrite ki roto i ngā awa rere maha mā roto i tētahi wehewehenga rere pūwero. Ka rehuhia e ia awa he pupuhi rere ki te impeller mai i ngā koki rerekē, ka huri maeneene te impeller i raro i te kaha whakakotahi o ngā pupuhi maha. Ka hurihia te nekehanga hurihuri hei raraunga rōrahi wai mā roto i tētahi pūnaha tuku taputapu tika, e whakaaturia ana i runga i te mata tatau.
Ngā Āhuatanga Matua
- Teitei o te Tika me te Pūmautanga o te Ine: Mā ngā rerenga maha-aronga ka taurite te ahotea o te impeller, ka whakaiti i te rerekētanga o te hurihanga. Ka taea e te tika o te ine te eke ki te Akomanga B, teitei ake rānei, me te kaha o te whakahokinga.
- Ātete Kaha ki te Whakararuraru me te Ātete Paku: Mā te rere ōrite o te wai ka whakaitihia te pānga o ngā poke ki te impeller, ka roa ake te ora o te mahi. He pai ake te urutau ki te kounga o te wai me te iti o te paru.
- Whānui te Awhe Rere: He pai mō ngā reiti rere iti me te reo, he whānui ake te awhe ine rere i ngā mita wai jet kotahi, e kapi ana i ngā caliber DN15 – DN40.
- Hanganga Pono me te Ora Ratonga Roa: Ko te hoahoa ara rere ā-roto kua arotauhia ka whakaiti i te ngaronga pūngao, ā, ko ngā wāhanga impeller me te tuku he mea hanga ki ngā rauemi ātete-kakahu (pēnei i te kowiri tira, ngā kirihou hangarau).
Ngā horopaki tono noa
Ngā whare noho rahi, rahi hoki, ngā whare tari, ngā whare arumoni, ngā hōtēra, ngā umanga ahumahi iti, me ētahi atu wā e whakamahia ana te wai me te rerekētanga o ngā rerenga. He whānuitia hoki te whakamahinga i roto i ngā kaupapa tuku wai e hiahia ana kia tino tika te ine.
