He aha te takirere o raro

He aha te Bellow Valve?

A takirere pupuhi, e mōhiotia ana ko te takirere hiri pupuhi, he momo takirere ahumahi i hangaia hei ārai katoa i te turuturu o te wai ki te taiao o waho. Ka whakamahia he pupuhi whakarewa hei huānga hiri hihiri i waenga i te kakau me te tinana o te takirere, hei whakakapi i te tikanga tākai tuku iho. He tino whai hua tēnei hoahoa i roto i ngā pūnaha wai paitini, morearea, mura, teitei-parakore rānei e tika ana kia whakaitihia, kia whakakorea rānei te turuturu.

Me pēhea te mahi a te takirere o raro

Ka whānui, ka whakawhāiti hoki ngā pūwero whakarewa i roto i te takirere i te nekehanga o te kakau takirere, ka hanga he hiri ā-hau e wehe ana i te wai i roto i te takirere mai i te āhuarangi. Ka whakapirihia ngā pūwero ki te kakau takirere me te taupoki, kia kore ai e turuturu te kakau i te wā e mahi ana. He maha ngā wā ka tāpirihia he hiri tākai tuarua hei tiaki rua.

Kei hea e whakamahia ai ngā takirere o raro

E whakamahia whānuitia ana ngā takirere o raro i roto i ngā ahumahi e hiahiatia ana te mahi kore turuturu:

• ①Te hanga kaipuke me te hanga waka (hei tauira, te hinu wahie me ngā pūnaha matū)

• ②Te tukatuka matū me te matū

• ③Rongoā

• ④Ngā tipu karihi me ngā tipu hiko

• ⑤Te hanga hiko hiko

• ⑥Ngā pūnaha cryogenic me te korehau-teitei

Ngā Painga o ngā Takirere o raro

• ①Kāore he turuturu o te kakau, he mea pai mō ngā mea kino, ngā mea mura rānei

• ②He roa te ora mahi nā te mea he ngāwari, he pakari hoki ngā pupuhi hau

• ③Pūnaha hiri takirua (pū + tākai)

• ④Te haumaru mahi teitei me te tiaki taiao

• ⑤Ka tutuki i nga paerewa ahumahi kaha mo te whakahaere tukunga (hei tauira, ISO 15848, TA-Luft)

Ngā Āhuatanga Matua

• ①Rauemi: Kowiri tira, kowiri tira waro, koranu rānei

• ②Ngā hononga pito: He mea whakarara, he mea miro, he mea whakarewa rānei

• ③Papa raro: He kowiri tira maha-papa hei ngāwari me te roa

• ④Whakahaere: Wira ā-ringa, wira rānei

• ⑤Ngā momo hoahoa: Kāhua takirere porowhita (tino noa), tauira koki, tauira-Y rānei
