4 ngā pōro piri
Ko te rauemi hiri nohoanga tino nui mōngā takirere pōroKo te polytetraoxyethylene (PTFE) he mea tairongo ki te nuinga o ngā matū matū, ā, he iti te tauwehenga waku, he pumau te mahi, he ngāwari ki te pakeke, he whānui te whānuitanga o te tono pāmahana me te mahi hiri. He tino pai ngā āhuatanga whānui. Heoi, ko ngā āhuatanga ā-tinana o te PTFE, tae atu ki te tauwehenga whānui teitei, te tairongo ki te rere makariri me te kawe wera ngoikore, me aro te hoahoa o ngā hiri nohoanga takirere ki ēnei āhuatanga. Kei roto hoki i te rauemi kirihou o te hiri nohoanga takirere te PTFE kua whakakīia, te nairona me te maha atu o ngā rauemi. Heoi, ina pakeke te rauemi hiri, ka pakaru te pono o te hiri, inā koa he iti te rerekētanga pēhanga. Hei tāpiri, ka taea hoki te whakamahi i te rapa hangai pēnei i te rapa butyl hei rauemi hiri nohoanga takirere, engari he iti noa iho ngā rongoā reo me te awhe pāmahana e tika ana. Hei tāpiri, ki te kore te reo e whakahinuhinuhia, tera pea ka aukati te pōro i te whakamahinga o te rapa hangai.
Hei whakatutuki i ngā whakaritenga whakamahinga o ngā tono ahumahi pēnei i te pāmahana teitei, te pēhanga teitei, te horo kaha, te roa o te ora, me ētahi atu, kua tino whanakehia ngā takirere pōro hiri-whakarewa i roto i ngā tau tekau kua pahure ake nei. Ina koa i ngā whenua ahumahi kua whanakehia, pēnei i te Hononga o Amerika, Itari, Tiamana, Pāniora, Hōrana, me ētahi atu, kua whakapaitia tonutia te hanganga o te takirere pōro, ā, kua whakauruhia ngā takirere pōro tanumia-tika-tinana katoa, ngā takirere pōro hiki, me ngā takirere pōro i roto i ngā paipa tawhiti, ngā taputapu whakamahine hinu, me ētahi atu. Kei te whānui haere te whakamahinga o te mara ahumahi, me te puta mai o ngā takirere pōro diameter nui (3050mm), te pēhanga teitei (70MPa) me te whānuitanga pāmahana whānui (-196 ~ 8159C), nō reira kua eke te hangarau o te takirere pōro ki tētahi taumata hou.
5 Te hoahoa me te hanga o te takirere pōro
Nā te whakamahinga o te Hoahoa Āwhina Rorohiko (CAD), te Hanganga Āwhina Rorohiko (CAM) me te Pūnaha Hanga Mulberry (FMS) i roto i te umanga takirere, kua eke te hoahoa me te hanga o ngā takirere pōro ki tētahi taumata hou. Ehara i te mea kua tino whakahoutia te tikanga tatau hoahoa takirere anake, engari kua whakaitihia hoki te mahi hoahoa taumaha me te auau o ngā kaimahi ngaio me ngā kaimahi hangarau, kia nui ake ai te kaha o ngā tohunga hangarau ki te whakapai ake, ki te whakapai ake i te mahi hua me te whakawhanaketanga hua hou, me te whakapoto i te huringa rangahau me te whanaketanga o ngā hua hou. , Whakapai ake i te hua o te mahi i roto i te huarahi whānui, ā, i roto i te tukanga rangahau me te whanaketanga o te takirere pōro hiri whakarewa momo tokotoko hiki, nā te whakamahinga o te CAD/CAM, kua puta he porowhita whānui toko papatahi i hangaia e te hoahoa āwhina-rorohiko me ngā taputapu mīhini CNC āwhina-rorohiko, he hiri whakarewa. Kāore he karawarawa, he kakahu rānei o te takirere pōro i te wā whakatuwheratanga me te kati, kia tino pai ake ai te mahi hiri me te roa o te ratonga o te takirere pōro. Ina whakatuwheratia katoatia te takirere pōro, he iti rawa te ātete rere, tata rite ki te kore, nō reira he whānui te whakamahinga o te takirere pōro rite te diameter i roto i ngā paipa hinu me te hau nā te mea he ngāwari ki te horoi i te paipa. Nā te mea ka murua te pōro o te takirere pōro i te wā e whakatuwheratia ana, e kati ana, ka taea te whakamahi i te nuinga o ngā takirere pōro ki roto i ngā rauemi kei roto ngā matūriki totoka iri. I runga i te rauemi o te mowhiti hiri, ka taea hoki te whakamahi ki roto i ngā rauemi paura me ngā mea kirikiri.
6 Ngā wā e tika ana mō te takirere pōro
I te mea he rapa, he nairona me te polytetraoxyethylene te tikanga o te whakamahi i te takirere pōro hei rauemi mō te mowhiti hiri nohoanga, ka whakawhāitihia tōna pāmahana whakamahinga e te rauemi mowhiti hiri nohoanga takirere. Ka tutuki te pānga tapahi o te whānui o te pōro mā te pēhi i te pōro whakarewa tetahi ki tetahi i waenga i ngā nohoanga takirere kirihou i raro i te mahi a te reo (takirere pōro mānu). I raro i te mahi a ētahi pēhanga whakapā, ka huri te mowhiti hiri nohoanga takirere i te āhua ngāwari me te āhua kirihou i ētahi wāhi. Ka taea e tēnei hurihanga te whakatikatika i te tika o te hanga me te taratara o te mata o te pōro, ā, ka whakarite i te mahi hiri o te takirere pōro.
Hei tāpiri, nā te mea he kirihou te nuinga o te wā e hangaia ana te mowhiti hiri nohoanga o te takirere pōro, me whakaaro ki te ātete ahi me te ātete ahi o te takirere pōro i te wā e whiriwhiri ana i te hanganga me te mahi a te takirere pōro, inā koa i roto i te hinu, te matū, te whakarewa me ētahi atu rāngai, i roto i ngā pāpāho mura me te pahū. Me aro nui ake te whakamahinga o ngā takirere pōro i roto i ngā taputapu me te pūnaha paipa o te United States ki te ātete ahi me te aukati ahi.
I te nuinga o te wā, i roto i te whakatikatika tūranga-rua, te mahi hiri tino pakari, te paru, te karawarawa, te hongere kaki, te mahi whakatuwhera me te kati tere (te whakatuwhera me te kati 1/4 hurihanga), te tapahi pēhanga teitei (te rerekētanga pēhanga nui), te haruru iti, te cavitation me te mimiti. I roto i ngā pūnaha paipa he iti te turuturu ki te hau, he iti te taipana mahi me te iti o te ātete wai, ka tūtohutia kia whakamahia ngā takirere pōro.
He pai hoki ngā takirere pōro mō ngā pūnaha paipa he māmā te hanganga, he iti te aukati pēhanga (he iti te rerekētanga pēhanga), ā, he waikura hoki.
Ka taea hoki te whakamahi i ngā takirere pōro i roto i ngā taputapu pāmahana iti (cryogenic) me ngā pūnaha paipa.
I roto i te pūnaha paipa hāora o te umanga whakarewa, e hiahiatia ana ngā takirere pōro kua oti te tukatuka tino tango hinu.
Ina hiahiatia ngā takirere pōro kua whakarewaina he whānui tonu, ina hiahiatia kia tanumia ngā paipa matua o te hinu me te hau ki raro i te whenua.
Mena e hiahiatia ana te whakarerekētanga o te mahi, me whiriwhiri he takirere pōro me te hanganga motuhake me te whakatuwheratanga āhua-V.
I roto i te hinu, te matū hinu, te matū, te hiko, me te hanganga tāone, ka taea te whakamahi i ngā takirere pōro hiri-ki-whakarewa mō ngā pūnaha paipa me ngā pāmahana mahi neke atu i te 200°C.
7 Ngā mātāpono mō te whakamahi i ngā takirere pōro
Mō ngā paipa hinu me te hau māori, arā, ngā paipa e hiahia ana kia horoia, kia tanumia ki te whenua, whakamahia ngā takirere pōro katoa-haere me ngā takirere pōro katoa-whakapiripiri; mō ngā paipa huna ki te whenua, whiriwhiria ngā takirere pōro katoa-haere, ngā takirere pōro kua whakapiripiripiritia rānei; ngā paipa peka, whiriwhiria te hononga takirere, te hononga whakarewa, te takirere pōro katoa-haere, te takirere pōro iti te diameter rānei.
Mō ngā paipa kawe me ngā taputapu rokiroki o te hinu parakore, whakamahia ngā takirere pōro kua whakakikoruatia.
Mō ngā paipa hau tāone me te hau māori, whakamahia ngā takirere pōro mānu me te hononga flange me te hononga miro ā-roto.
I roto i te pūnaha paipa hāora i roto i te pūnaha whakarewa, me whakamahi he takirere pōro pumau kua oti te tukatuka tango hinu me te hononga flanged.
Mō ngā pūnaha paipa me ngā taputapu pāmahana-iti, me whakamahi ngā takirere pōro pāmahana-iti me ngā taupoki. I roto i te pūnaha paipa o te wāhanga pakaru catalytic o te wāhanga whakamahine hinu, ka taea te whiriwhiri i tētahi takirere pōro momo-hiki.
I roto i ngā taputapu me ngā pūnaha paipa o ngā mea waikura pērā i te waikawa me te kawakore i roto i ngā pūnaha matū, he mea tika kia whakamahia ngā takirere pōro kowiri tira katoa i hangaia ki te kowiri tira austenitic me te polytetraoxyethylene hei nohoanga me te mowhiti hiri.
Ka taea te whakamahi i ngā takirere pōro hiri whakarewa-ki-whakarewa i roto i ngā pūnaha paipa, i ngā taputapu rānei mō ngā pāpāho pāmahana-tiketike i roto i ngā pūnaha whakarewa, ngā pūnaha hiko, ngā whakaurunga hinu-matū, me ngā pūnaha whakamahana tāone.
Mēnā e hiahiatia ana te whakarerekētanga rere, ka taea te whiriwhiri i te takirere pōro hiko, te takirere hau, te takirere pōro hiko rānei me te whakatuwheratanga āhua-V.
