He maitai hanga-ā-ringa pāmahana teitei, pēhanga teitei, takirere pōro whakairi-ā-ringa iti, wheketere Haina
He aha te takirere pōro trunnion maitai hanga?
A takirere pōro trunnion maitai whakapūmauko 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.
Ka panaia te nohoanga o runga e te pēhanga o te paipa ki te pōro tūmau kia panaia ai te nohoanga o runga e te pēhanga raina ki runga i te pōro, kia hiritia ai. Ka mimitihia e te punga ā-ringa o te pōro te pana mai i te pēhanga raina, ka ārai i te waku nui i waenga i te pōro me ngā nohoanga, nō reira ahakoa te pēhanga mahi katoa, ka noho tonu te taipana whakahaere he iti. He tino painga tēnei ina whakaohohia te takirere pōro nā te mea ka whakaitihia te rahi o te kaiwhakaoho, ā, nō reira ka whakaitihia te utu whānui o te mōkihi whakaoho takirere. Kei te wātea te trunnion mō ngā rahi katoa me ngā akomanga pēhanga katoa, engari ko te nuinga mō ngā rahi nui me ngā āhuatanga pēhanga teitei.
Ngā āhuatanga matua o te takirere pōro trunnion 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.
2. Te Taipana Whakahaere Iti
Ka whakamahia e te takirere pōro paipa trunnion te hanganga pōro trunnion me te nohoanga takirere mānu, kia iti ake ai te taipana i raro i te pēhanga whakahaere. Ka whakamahia e ia te PTFE whakahinuhinu-ake me te peera reti whakarewa hei whakaiti i te tauwehenga waku ki te iti rawa me te kakau kaha teitei me te matotoru teitei.
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
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.
5. Hanganga Ārai-pūmau
Kua hangaia te takirere pōro ki te hanganga anti-static, ā, e whakamahi ana i te taputapu tuku hiko static hei hanga tika i tētahi awa static i waenga i te pōro me te tinana mā te kakau, kia taea ai te tuku i te hiko static i puta mai i te waku i te wā e whakatuwhera ana, e kati ana hoki te pōro me te nohoanga mā te paipa, kia kore ai e puta he ahi, he pahūtanga rānei nā te mura static, kia mau ai te haumaru o te pūnaha.
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.

Te tuhi matua o te whakamāmā i te pēhanga o te kōhao takirere pōro ki te awa o runga me te hiri o te awa o raro
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.
