Haidrāwetika me Pneumatika

Ko ngā umanga hīoraupiko me ngā umanga puhahuha ko te takotoranga me ngā wāhi whakamahi matua o te hangarau whakaputa, e mōhiotia ana mā te herekenga ki te rere o te wai (hinu, he puia rānei) hei tuku kaha. Ko te noho pai o te whakaputa e whakatau ana pea ai te take ka mahi te punaha, te angaima, me te haumātanga.

Wāhi whakamahi: Te whakaputa o te silihini hīoraupiko (silihini hinu)

·Kombiniti whakaputa: Ko tēnei tētahi "pūnaha whakaputa" katoa e whai wāhi mai ana:

·Whakaputa matua (whakaputa pihiti): e manaaki ana i te pēhitia mahi o te punaha, ā, e aukati ana i te rere o te hinu pēhia mai i tētahi taha ki tētahi (rere-kiokio o roto).

·Piringa aratohu: e aukati ana i te pihiti kia kaua e whakapā ki te metara o te silihini, e horoi ai i te mira me te wareware.

·Tāpahi pou (pōti tohu + tāpahi pou matua + pōti karapoti tohu): he waiho hei āki ai i te rīwai hiko, ā, he kātahi ka karapoti i ngā kirikiri i kawea mai e te pou pūtau.

·Ngā matērihi matua: Ko te Polyurethane (PU), te rāpaki nitrile (NBR), i te mea ko ngā matērihi composite PTFE (polytetrafluoroethylene) tikangia hoki mō te mahi pai.

·Takotoranga pono: Te pūtu o te pūtu o te takotoranga

·Āhuatanga: Ka whakauru tonu ngā kāmupene ki ngā pūtake, kei reira ka pāngia te pūtu hiko ki ngā uta tino nui, ki ngā taiao kirikiri hoki.

·Ngā putanga herenga: Mēnā ka wareware te tāpahi matua o te pūtau, ka pā ki te rere o roto, ka whakaaturia e te ngoikera, ka heke haere te takotoranga (e mōhiotia ana ko te "heke ihu"), ā, kaore e taea e te kāmupene te mahi pono, ka heke te uara. Mēnā ka herengia te tāpahi o te pou pūtau, ka pā ki te rere o te hinu, ka pā ki te taiao, ā, ka taea pea te iti noa i te hinu, ka pā ki te herenga o te pūhiko, ā, ētahi atu herenga anō.

·Te take tuku: Ko te takotoranga o ngā pūtau silikaiko tuarangi kaha e whakarite ana i te mahi ātawhai o ngā kōhatu mō ngā haora miriona, ka aronga atu i ngā wā kore-āhua me ngā utu matatau e hua ana i ngā raru pūtau.
