Ki te hiahia koe ki te neke i ngā wai matotoru, ngā wai whakakoi, ngā wai ngawari rānei, kua tūtaki pea koe ki tētahiPapu Diaphragm HauE mōhiotia ana ēnei papu mō ō rātou whakamahinga maha me te hoahoa pakari, he tino whai hua ēnei papu i roto i ngā ahumahi mai i te hanga ki te maimoatanga waipara. Engari he aha tonu te mea e tupu ana i roto i tētahi? Ka whakamāramahia e tēnei tuhinga te mahi māmā engari he tino pai o te papu AODD (Air Operated Double Diaphragm).

He aha te papu diaphragm hau?

An Papu Diaphragm Hau, e tika ana kia karangatia ko te Papu Āwhiowhio Takirua e Whakahaeretia ana e te Hau (AODD), he momo papu nekehanga pai e whakamahi ana i te hau kōpeke hei pūtake hiko. E whakamahi ana i ngā āwhiowhio ngāwari e rua e hoki whakamuri ana, e hoki whakamuri ana hei hanga i tētahi rūma rangitahi e kukume ana, e pana ana hoki i te wai e papua ana.

Ko tōna painga matua he ātete ki te pahūtanga (ko te pūtake hiko he hau, ehara i te hiko) ā, ka taea te maroke tonu me te kore e pakaru. Ka taea e ia te whakahaere i te whānuitanga o ngā wai, mai i te wai ma ki ngā paru matotoru me ngā paru kua ki tonu i ngā totoka.

Ngā Wāhanga Matua: He aha kei roto?

Hei mārama ki tana mahi, me mōhio koe ki ōna wāhanga matua:

1. Ngā Diaphragm e Rua: Ngā kiriuhi ngāwari (he maha ngā wā he mea hanga ki te rapa, ki te thermoplastic, ki ētahi atu elastomers rānei) e neke whakamua ana, e anga whakamua ana.

2. Ngā Rūma Wai e Rua: Ngā āputa e puritia ai te wai i mua atu, me muri i te papua.

3. Ngā Huinga Takirere Hau e Rua: Ko te "roro" o te papu e whakahaere ana i te hau kōpeke.

4. He Pūwero Hau Waenga: Ka neke i te rere o te hau mai i tetahi taha ki tetahi taha.

5. Ngā Pōro Tirotiro: Kotahi te huinga ki te taha tomo, kotahi ki te taha putanga mō ia rūma. Mā ēnei pōro ka rere te wai i te taha kotahi anake.

Te Huringa Papu 4-Hipanga: Me Pēhea te Mahi

He huringa tonu te mahi, e whā ngā mahi matua. Whakaarohia te tīmatanga o te papu me te pēhitanga o te puku maui ki roto.

Hipanga 1: Whiu Mauī - Tukunga

• Ka anga te hau kōpeke ki muri i te diaphragm maui, ka panaia ki roto ki te ruma wai.

• Ka pēhanga te rūma i tēnei, ka panaia hoki te wai ki waho.

• Ka panaia te pōro tirotiro putanga maui i tōna nohoanga, kia puta ai te wai mā te putanga tuku.

• I te wā kotahi, ka hiritia te pōro tirotiro tomokanga maui ki tōna nohoanga e te pēhanga, kia kore ai e hoki whakamuri.

Hipanga 2: Whiu Mauī - Hopu Wātahi ki te Matau

• I te panaia o te diaphragm maui ki roto, ka kumea te diaphragm matau ki waho. Nā te mea e honoa ana ngā diaphragm e rua e tētahi pou kotahi.

• Ka hangaia he korehau i te rūma wai i te taha matau e tēnei hokinga whakamuri.

• Ka mimitihia te wai e tēnei korehau ki roto i te rūma mai i te putanga whakauru, ka hiki ake i te pōro tirotiro tomokanga matau i tōna nohoanga.

• Ka noho hiri tonu te pōro taki putanga matau i te pēhanga o te hau.

Hipanga 3: Te Huringa

• Kia oti te whiu a te diaphragm maui, ka neke aunoa te pūnaha takirere hau pokapū. Ka hurihia te hau kōpeke mai i te taha maui ki te taha matau.

Hipanga 4: Te Whiu Matau - Te Tukunga me te Whakaurunga Mauī

• Ka huri te tukanga ināianei.

• Ka panaia te diaphragm matau e te hau kōpeke ki roto, ka tukuna te wai i mimitihia mai.

• I te wā kotahi, ka kumea whakamuri te diaphragm maui e hono ana, ka whakakī anō i tōna rūma ki te wai hou mai i te tomokanga.

Ka pūrua aunoa tēnei huringa, whakamuri, whakamuri, ka hanga he rere maeneene, he tino whai hua mō te papu i ngā rauemi uaua.

Ngā Painga Matua o te Hoahoa o te Papu Diaphragm Hau

He maha ngā painga nui o tēnei tikanga ahurei:

• Ka Maroke: Nā te mea kāore he wāhanga o roto e hiahia ana ki te wai hei whakahinuhinu, ka taea e te papu AODD te maroke tonu me te kore e kino.

• Te Whakapūmau-ā-Whaiaro: He tino pai ēnei hei whakapūmau-ā-whaiaro, ā, ka taea te tango i te wai mai i ētahi putu i raro i te papu.

• Rere me te Pēhanga Taurangi: Ka taea te whakarerekē i te tere rere mā te whakanui, te whakaiti rānei i te pēhanga hau e tomo mai ana. Mā te kati i te takirere tukunga ka mutu te papu; e kore e memeha, e mura rānei pērā i te papu toremi.

• Ka Pupuri i ngā Mea Totoka me ngā Mea Whakakoi: Mā te whānui o ngā ara rere me te hoahoa porowhita ārai ka taea e te papu te pupuri i ngā mea totoka me ngā rauemi matotoru ka ārai i ētahi atu papu.

• Ārai-Pahū: Nā te mea kāore he mōtini hiko, ā, ko te pūtake hiko he hau kōpeke, he tino haumaru ēnei mō te whakamahi i roto i ngā taiao morearea.

• Hoahoa Kore-Hīra: Kāore he hiri ā-ringa e turuturu, e rahua rānei, ka tino whakaiti i te mahi tiaki.

Ngā Taupānga Noa

Nā te pakari o te hoahoa, e whakamahia ana ngā papu AODD ki ngā wāhi katoa:

• Te Whakawhiti Matū: Ngā waikawa, ngā whakarewa, ngā piripiri, me ngā peita.

• Te Keri me te Hanga: Te tango i ngā poka wai me te neke i te paru me ngā mea paru.

• Kai me te Inu: Te whakahaere i ngā hua matotoru pēnei i te kirīmi, te whakapiri, me ngā puranga he totoka (pēnei i ngā mongamonga hua).

• Te Maimoatanga o ngā Wai Para: Te neke i ngā mea whakarewa, ngā paru, me ngā matū maimoatanga.

• Ahumahi Whānui: Te uta, te tango i ngā rauemi, me te whakawhiti i te tini o ngā rauemi.

Whakamutunga

Tepapu hau hauE mahi ana i runga i tētahi mātāpono tino māmā, arā, ko te pēhanga hau tauutuutu me ngā diaphragm tauutuutu. Ko tēnei ngāwari te pūtake o tōna pono me tōna whānui whakamiharo. Ahakoa kei te mahi koe me ngā wai ngawari e aro ana ki te kutikuti, me ngā paru whakakoi tino uaua rānei, ka whakaratohia e te papu AODD he otinga haumaru, whai hua, me te whakahaere mō ngā wero papu uaua.
