API 6D API608 Porowhita Poro Whakamau Rino Maka Hangaia ki te wheketere Haina
He aha te takirere pōro trunnion maitai whakarewa?
A Takirere pōro whakarewa maitaiko te tikanga he herenga te pōro e ngā peera, ā, ka taea anake te huri, ko te nuinga o te kawenga waipēhi e tautokona ana e ngā herenga Pūnaha, ka hua ake he iti te pēhanga peera, ā, kāore he ngenge o te pou.
Ko ngā painga o te hoahoa pōro trunnion ko te iti o te taipana whakahaere, te ngāwari o te whakahaere, te iti o te pakaru o te nohoanga (mā te wehewehe o te kakau/pōro ka ārai i te uta taha me te pakaru o ngā nohoanga o raro, ka whakapai ake i te mahi me te roa o te ratonga), te mahi hiri pai rawa atu i te pēhanga teitei me te pēhanga iti (ka whakamahia he pūnaha puna motuhake me te pēhanga raina o runga hei hiri ki te pōro tūmau mō ngā tono pēhanga iti me te pēhanga teitei).
Ngā āhuatanga matua o te takirere pōro whakarewa maitai NORTECH
1.Poraka Takirua me te Toto (DBB)
Ina kati te takirere, ā, ka whakawāteahia te kōhao waenga mā te takirere tuku, ka ārai motuhake ngā nohoanga o runga me raro. Ko tētahi atu mahi a te taputapu tuku ko te tirotiro i te nohoanga takirere mēnā he turuturu i te wā whakamātautau. Hei tāpiri, ka taea te horoi i ngā putunga i roto i te tinana mā te taputapu tuku. Kua hangaia te taputapu tuku hei whakaiti i te kino o te nohoanga nā ngā poke o roto i te reo.
3. Pūrere Hiri Āwhati
Ko ngā takirere pōro he nui ake i te 6' te whānui (DN150), he rite rānei ki te 6' te whānui, he mea hanga katoa ki te taputapu werohanga hiri i runga i te kakau me te nohoanga. Ina pakaru te mowhiti nohoanga, te mowhiti O rānei o te kakau nā te aituā, ka taea te werohanga i te hiri e rite ana mā te taputapu werohanga hiri hei karo i te turuturu reo ki runga i te mowhiti nohoanga me te kakau. Mēnā e tika ana, ka taea te whakamahi i te pūnaha hiri āwhina hei horoi me te whakahinuhinu i te nohoanga kia mau tonu ai tōna ma.
Pūrere Werohanga Hiri
4. Hoahoa Hanganga Ārai Ahi
Mēnā ka puta he ahi i te wā e whakamahia ana te takirere, ka pirau, ka pakaru rānei te mowhiti nohoanga, te mowhiti O kakau me te mowhiti O waenga o te flange i hangaia ki te PTFE, te rapa o ētahi atu rauemi kore-whakarewa i raro i te pāmahana tiketike. I raro i te pēhanga o te reo, ka pana tere te takirere pōro i te pupuri nohoanga ki te pōro kia pa ai te mowhiti hiri whakarewa ki te pōro, kia hanga ai he hanganga hiri whakarewa-ki-whakarewa āwhina, ka taea te whakahaere pai i te turuturu o te takirere. Ko te hoahoa hanganga ātete ahi o te takirere pōro paipa trunnion e tutuki ana i ngā whakaritenga o te API 607, API 6FA, BS 6755 me ētahi atu paerewa.
6. Hanganga hiri nohoanga pono
Ka whakatinanahia te hiri o te nohoanga mā roto i ngā pupuri nohoanga e rua e mānu ana, ka taea te mānu ki te taha tuaka hei aukati i te wai, tae atu ki te hiri pōro me te hiri tinana. Ka whakatinanahia te hiri pēhanga iti o te nohoanga takirere mā te whakakī i mua i te puna. Hei tāpiri, kua hangaia te pānga piston o te nohoanga takirere kia tika ai te hiri pēhanga teitei mā te pēhanga o te reo tonu. Ka taea te whakatinana i ngā momo hiri pōro e rua e whai ake nei.
7. Hiritanga Kotahi
(Whakaora Pēhanga Aunoa i te Kōhao Waenga o te Takirere) I te nuinga o te wā, ka whakamahia te hanganga hiri kotahi. Arā, ko te hiri o runga anake. I te mea ka whakamahia ngā nohoanga hiri o runga me raro kua utaina ki te puna motuhake, ka taea e te pēhanga nui rawa o roto o te kōhao takirere te wikitoria i te pānga whakakī o mua o te puna, kia tukuna ai te nohoanga mai i te pōro, kia puta ai te whakaora pēhanga aunoa ki te taha o raro. Te taha o runga: Ina neke te nohoanga i te taha o te takirere, ka puta he kaha whakamuri ki te A1 i te pēhanga "P" e pā ana ki te taha o runga (tomokanga). I te mea he teitei ake a A2 i a A1, A2-A1=B1, ka pana te kaha ki te B1 i te nohoanga ki te pōro, ā, ka puta he hiri piri o te taha o runga.
Te taha whakararo: Kia piki ake te pēhanga "Pb" i roto i te kōhao takirere, ka nui ake te kaha e pā ana ki a A3 i tērā i a A4. Nā te mea ko A3-A4=B2, ka hinga te rerekētanga pēhanga i runga i a B2 i te kaha o te puna kia tukuna te nohoanga mai i te pōro, kia puta ai te whakamamatanga pēhanga o te kōhao takirere ki te taha whakararo. I muri iho, ka hiritia anō te nohoanga me te pōro i raro i te mahi puna.
8. Hiri Takirua (Pōtene Takirua)
Ka taea te hoahoa i te takirere pōro paipa trunnion me te hanganga hiri takirua i mua me muri i te pōro mō ētahi āhuatanga ratonga motuhake me ngā whakaritenga a te kaiwhakamahi. He pānga piston takirua tōna. I raro i te āhua noa, ka whakamahia e te takirere te hiri tuatahi. Ina pakaru te hiri o te nohoanga tuatahi, ā, ka turuturu, ka taea e te nohoanga tuarua te mahi hiri me te whakarei ake i te pono o te hiri. Ka whakamahia e te nohoanga te hanganga whakakotahi. Ko te hiri tuatahi he hiri whakarewa ki te whakarewa. Ko te hiri tuarua he mowhiti O rapa fluorine hei whakarite kia eke te takirere pōro ki te hiri taumata mirumiru. Ina tino iti te rerekētanga pēhanga, ka pēhia e te nohoanga hiri te pōro mā roto i te mahi puna kia tutuki ai te hiri tuatahi. Ina piki ake te rerekētanga pēhanga, ka piki ake te kaha hiri o te nohoanga me te tinana kia piri ai te nohoanga me te pōro, kia pai ai te mahi hiri.
Te hiritanga tuatahi: Te awa ki runga.
Ina iti iho te rerekētanga pēhanga, ina kore rānei he rerekētanga pēhanga, ka neke te nohoanga mānu i te taha o te takirere i raro i te mahi a te puna, ka pana i te nohoanga ki te pōro kia mau tonu te hiri. Ina teitei ake te kaha o te nohoanga takirere i te kaha e pā ana ki te rohe A1, A2- A1=B1. Nō reira, ka panaia e te kaha i roto i te B1 te nohoanga ki te Pōro, ā, ka tutuki te hiritanga o te taha whakarunga.
9. Pūrere Āwhina Haumaru
I te mea kua hangaia te takirere pōro me te hiri tuatahi me te tuarua matatau e whai pānga piston takirua, ā, kāore e taea e te kōhao waenga te whakatutuki i te whakahekenga pēhanga aunoa, me tāuta te takirere haumaru ki te tinana hei ārai i te tūponotanga o te kino nui rawa o te pēhanga i roto i te kōhao takirere ka puta mai i te whakawhānui wera o te reo. Ko te hononga o te takirere haumaru ko te NPT 1/2. Ko tētahi atu mea hei mōhio ko te reo o te takirere haumaru ka tukuna tika ki te hau. Mena kāore e whakaaetia te tukunga tika ki te hau, ka tūtohu mātou kia whakamahia te takirere pōro me te hanganga motuhake o te whakahekenga pēhanga aunoa ki te awa o runga. Tirohia ngā mea e whai ake nei mō ētahi atu taipitopito. Tena koa tohua mai i roto i te raupapa mena kāore koe e hiahia ki te takirere haumaru, mena rānei e hiahia ana koe ki te whakamahi i te takirere pōro me te hanganga motuhake o te whakahekenga pēhanga aunoa ki te awa o runga.

12. Ātete ki te Waikura me te Ātete ki te Ahotea o te Whāriki
Kei te toe he ātete ki te waikura mō te matotoru o te pakitara o te tinana.
Ko te kakau maitai waro, te pou pumau, te pōro, te nohoanga me te mowhiti nohoanga kua pania ki te nikara matū e ai ki te ASTM B733 me te B656. Hei tāpiri, he maha ngā rauemi ātete waikura e wātea ana mā ngā kaiwhakamahi ki te whiriwhiri. E ai ki ngā hiahia o te kiritaki, ka taea te whiriwhiri i ngā rauemi takirere e ai ki te NACE MR 0175 / ISO 15156, NACE MR 0103 rānei, ā, me whakahaere te mana kounga me te tirotiro kounga tino pakari i te wā hangahanga kia tutuki katoa ai ngā whakaritenga o ngā paerewa me te whakatutuki i ngā tikanga ratonga i roto i te taiao whanariki.
11.Kakau Ārai Pupuhi
He hanganga ātete-pupuhi te kākano. Kua hoahoatia te kākano me te tapuwae ki raro kia kore ai te kākano e pupuhihia e te reo ahakoa te pikinga o te pēhanga rerekē i roto i te kōhao takirere.
Kātua Ārai-Pahū
13. Kakau Toronga
Mō te takirere tāmau, ka taea te tuku i te kakau toronga mēnā e hiahiatia ana te mahi whenua. Ko te kakau toronga he mea tito mai i te kakau, te takirere werohanga hiri, me te takirere waikeri ka taea te toro atu ki runga hei whakahaere i te ngāwari o te mahi. Me tohu e ngā kaiwhakamahi ngā whakaritenga me te roa o te kakau toronga ina tuku ota ana. Mō te takirere pōro e peia ana e ngā kaiwhakaoho hiko, hau me te hau - waipēhi, me roa te kakau toronga mai i waenganui o te paipa ki te flange o runga.
