Ko ngā tohu takirere pōro he whakaaturanga whakairoiro whānui e whakamahia ana i roto ingā tuhi hangarau, P&ID (Ngā Hoahoa Paipa me ngā Taputapu), me ngā tuhinga hangarau. Ka tukuna e ēnei tohu paerewa ngā mōhiohio matatini mō te takirere kia poto, kia taea ai e ngā tohunga o te ao te tautuhi me te whakamārama tonutakirere pōrongā mahi i roto i ngā pūnaha wai.
He aha te Takirere Pōro?
He takirere pōro he takirere huri-hauwhā e whakamahi ana i tētahi pōro tuwhera, hurihuri hei whakahaere i te rere o te wai. Ina hurihia te pōro e te kakau, e te kaiwhakaoho rānei ki te 90 nekehanga, ka hāngai te poka ki te paipa hei tuku i te rere, hei ārai poutū rānei. E mōhiotia ana mō tōna hiri piri, te tere o te mahi, me te roa, e whakamahia whānuitia ana ngā takirere pōro puta noa i ngā ahumahi maha.
Ngā Tohu Takirere Pōro i roto i ngā P&ID
I roto i ngā hoahoa P&ID, ka whakaatuhia ngā takirere pōro e te huinga o ngā tohu taketake e tohu ana i tō rātou momo, te tikanga whakaoho, me te aratau rahunga. Ko te tohu tino noa ko te porowhita me te rārangi whakarara, he porowhita iti rānei i roto, e tohu ana i te pōro me tōna ara rere. Ka tohu ngā whakarerekētanga tāpiri mēnā he mea whakahaere ā-ringa te takirere, he hiko, he hauhautanga, he āhuatanga motuhake rānei.
Hei tauira:
• Takirere Pōro PaerewaHe porowhita me te rārangi whakapae e puta ana i roto.
• Takirere Pōro MiihiniKo te tohu ōrite ki te tohu "M" te tohu whakatere hiko rānei.
• Takirere Pōro Solenoid: He maha ngā wā e whakaaturia ana me te tohu whakatere hikohiko.
Ngā Huānga Matua o ngā Tohu Takirere Pōro
*(I runga i ngā Paerewa ISO/ANSI/ISA-S5.1)*
1. Huānga Pōro Porowhita
Ko te tohu matua he porowhita e tohu ana i te pōro porowhita o te takirere. E tohu ana tēnei huānga mēnā kei tepūnga katoa (putanga katoa)rāneipūwero iti (pūwero iti)- he mea nui mō te whai huatanga o te whakahaere rere.
2. Ngā Pere Aronga Hurihanga
E whakaatu ana ngā pere i te hurihanga o te pōro:
↗Hurihanga karaka = TakirereTUWHERA
↖Te hurihanga whakamuri-karaka = TakirereKUA KATIA
*(Ko te hurihanga 90° te paerewa mō ngā takirere pōro huri-hauwhā)*
3. Ngā Tohu Putanga Tomokanga/Putanga
Ko ngā rārangi/pere e tohu ana i ngā ara rere:
– Ngā hononga-T poutū = Ngā whakawhitiwhitinga paipa
– Ngā pere whakapae = Te ahunga rere tuatahi
– Ngā tohu tapatoru = Ngā tauranga pēhanga
4. Ngā Tohu Hangarau Tāpiri
E whakamārama ana ngā tuhipoka tāpiri:
– Te pēhanga mahi (hei tauira, PN16, Akomanga 150)
– Awhe pāmahana (°C/°F)
– Ngā waehere rauemi (SS304, CS, PTFE)
– Momo pūwhakaoho (ā-ringa, hau, hiko)

Tohutohu mō te Pānui i ngā P&ID me ngā Tohu Takirere Pōro
• Me tirotiro tonu ki te tohu, ki te pūrākau rānei e pā ana ki te hoahoa.
• Kia mōhio ki te tikanga whakaoho me te tūranga rahunga.
• Manatokohia te ahunga rere me te tau o te takirere.
• Tirohia ngātahitia ngā pepa raraunga me ngā whakaritenga mō te takirere.
He aha te Hiranga o ngā Paerewa Tohu i roto i te Hangarau
- ISO 14617 / ANSI/ISA-S5.1whakarite kia ōrite te ao whānui
- He rerekētanga motuhake kei ia ahumahi (hinu/hau me te rongoā)

Ngā Takirere Pōro me ētahi atu momo Takirere
Ahakoa he maha ngā whakamahinga o ngā takirere pōro, he mea nui kia wehewehea rātou mai i ētahi atu takirere noa:
• Ngā Takirere Kēti:Whakamahia mō te ratonga whakaweto/whakakā i roto i ngā pūnaha pēhanga teitei engari he puhoi ake te whakahaere.
• Ngā Takirere Porowhita:He pai ake mō te whakawhāiti me te whakahaere i te rere o te wai.
• Ngā Takirere Pūrerehua:He kiato, he iti hoki te utu mō ngā paipa nunui, engari he iti ake te whai huatanga ina whakawetohia i te pēhanga teitei.
• Ngā Takirere Tirotiro:Tukua kia rere te rere i te taha kotahi anake.
He pai ake te hiri me te tere o te mahi a ngā takirere pōro i te nuinga o ngā kōwhiringa kē atu, inā koa i ngā tono huringa-tiketike.
