He aha te takirere pūrerehua: Ngā tohutohu taipitopito e tika ana

He aha te takirere pūrerehua

A takirere pūrerehuaHe takirere huri-hauwhā tēnei, he kōpae hurihuri (pereti pūrerehua) e piri ana ki te kakau o waenganui. Mā tēnei hoahoa kiato ka taea te whakahaere tere i te rere, te wehe rānei i roto i ngā paipa. He whānuitia te whakamahinga puta noa i ngā ahumahi, ā, he tino pai ngā takirere pūrerehua i roto i ngā tono e hiahia ana ki ngā otinga utu-whai hua, māmā hoki, me te iti o te hekenga pēhanga.

Hanganga o te Takirere Pūrerehua: 4 Ngā Wāhanga Matua

1. Tinana TakirereHe whare porotaka (rino maka, rino kore waikura, rino ngāwari rānei) me ngā pito he flanged/lug/weld.

2. Kōpae TakirereHe pereti hurihuri hei whakahaere i te rere – e wātea ana i ngā whirihoranga porowhita, takirua/takitoru.

3. Kākano: Hononga ai te actuator ki te kōpae mō te tuku taipana.

4. NohoangaMata hiri (rapa ngohengohe, PTFE, whakarewa rānei) kia kore ai e turuturu.

Me pēhea te mahi a ngā takirere pūrerehua

He wāhanga matua ngā takirere pūrerehua i roto i ngā pūnaha whakahaere wai hou, e whakanuia ana mō tōna māmā, te hoahoa kiato, me te tere o te mahi. Engari me pēhea te mahi a tēnei takirere maha-whakamahinga?

Te Kaupapa Whakahaere Matua: Te Kōpae Hurihuri

Ko te ngākau o te takirere pūrerehua he kōpae porowhita (he vane rānei) e mau ana ki runga i tētahi kakau hurihuri i roto i te pū o te paipa. Ka tutuki katoa te whakahaere wai mā te nekehanga porowhita o te kōpae:

Ka huri te kōpae 90° i waenganui i:

-Tuwhera Katoa: Ka whakarara te kōpae ki te rere (he iti noa te ngaronga pēhanga)

-Kua Kati Katoa: Ka rere poutū ngā poraka kōpae ki te paipa

Te Whakatuwheratanga me te Tīmatanga Rere: Te Hurihuri hei Whakaae i te Rere

• Ina whakahohea (ā-ringa mā te wira ā-ringa, mā te aunoa rānei mā ngā pūkaha hiko/hau), ka hurihia e te kakau te kōpae mai i tōna tūranga kati (tū tika ki te rere) ki te tūranga tuwhera.

• I te hurihuri o te kōpae (mai i te 0° ki te 90° te nuinga), ka neke atu i te nohoanga takirere, ka hangaia he ara mō te rere o te wai i ōna taha, me/ranei mā roto i tētahi pūaha pokapū mēnā kei reira.

• E pā tika ana te koki whakatuwheratanga ki te kaha rere, e āhei ai te whakarerekētanga tika i runga i te hiahia o te pūnaha.

Te Whakahaere Rere Tika: Ka Whakahau te Koki i te Tere

• Ko tētahi o ngā kaha matua o ngā takirere pūrerehua ko tōna kaha ki te whakawhāiti i te hau. Mā te whakahaere i te koki hurihuri o te kōpae, ka taea e ngā kaiwhakahaere te whakahaere i te rere o te kōpae.

• I te hurihanga tata ki te 90° (he kōpae e whakarara ana ki te rere), he iti noa ngā arai e tukuna ana e te kōpae, e whakarato ana i te rere tata ki te kī o te rohe paipa me te tere rere mōrahi.

• I ngā koki waenga (hei tauira, 30°, 45°, 60°), ka āraia te ara rere e te kōpae, ka whakaitihia te horahanga rere, ā, ka taea te whakahaere pai i te rere.

Whakaweto Pai: Te Hiri i te Rere

Hei aukati rawa i te rere, ka hurihia te kōpae e te actuator ki te tūranga 0° (kia poutū ki te rere).

I tēnei tūranga, ka pēhi kaha te taha o te kōpae ki tētahi nohoanga elastomeric pakari (hei tauira, EPDM, Nitrile, PTFE) kua herea, kua puritia rānei ki roto i te tinana takirere, ka hanga he hiri piri-mirumiru hei wehe katoa i te rere.

Ngā Mahi Tāpiri: Ngā Taupānga Whakahaere Taumata

Haunga te whakakā/whakaweto me te whakawhāiti i te wai, ka taea te whakamahi i ngā takirere pūrerehua hei whakahaere i te taumata (upoko) i roto i ngā tāke, i ngā puna wai rānei. Mā te whakarerekē i te koki o te kōpae, ka whakarerekētia te tere rere o te putanga, ka pā kino ki te taumata wai o runga.

Ngā Āhuatanga Matua o te Mahi me ngā Take Kōwhiringa:

Mā te mārama ki ēnei mātāpono whakahaere ka kitea ngā āhuatanga mahi nui e tika ana mō te whiriwhiri me te tono tika mō te takirere:

√Te Hekenga Pēhanga (Ngaronga):He tino iti te hekenga pēhanga o ngā takirere pūrerehua ina tuwhera katoa (nā te iti o te aukati) ā, kāore rawa he hekenga ina kati (hiri katoa). Heoi, i ngā tūranga tuwhera ā-wāhanga (whakatere), ka puta he aueuetanga nui me te raruraru rere i te kōpae, ka nui ake te ngaronga pēhanga ki te whakataurite ki ngā takirere whānui pērā i ngā takirere kuaha. He mea nui tēnei mō te whai huatanga o te pūngao i roto i te ratonga whakatere.

√Ngā Pāpāho e Tika ana:He tino pai ngā takirere pūrerehua ki ngā wai, ngā hau, me ngā kohu ma – arā, he mea ngāwari te "kutikuti" e te kōpae.

√Ngā paru, ngā mea rānei he nui te ihirangi totoka:Ka taea e ngā matūriki whakakoi te whakakino i te taha o te kōpae, te kino hoki i te nohoanga ngohengohe, ka whakararu i te hiri. Ka tūtohu mātou kia whakamahiaNgā Takirere Pūrerehua Nohoanga Whakarewarānei te takirere kūaha paru

Kāore i te tūtohutia mō ēnei mea i te nuinga o te wā:

χHe wai tino matotoru, he pāpāho rānei e ngāwari ana ki te whakatioataKa taea e ēnei te piri, te aukati i te katinga katoa, te kino rānei i te nohoanga. Ka tūtohu mātou kia whakamahia ngā Waewae Pōro Wāhanga.
