He mea noa te whakamahi i ngā paipa rino tapawhā, tapawhā rānei i roto i ngā kaupapa hangahanga, ā, he mea whānuitia hoki mō ngā tautoko tāutanga paipa, te urunga rangitahi ki te papaanga, ngā kaupapa hiko, te takere whakapaipai, me ētahi atu.
Ina nui te rahi o te paipa maitai tapawhā rite, ka taea e tātou te wareware i te pānga o ngā kokonga porowhita ki te taumaha, hei tauira, he paipa tapawhā rite i roto i te paipa, he iti noa te taumaha e ngaro ana i ngā kokonga porowhita e whā mō tētahi wāhanga tino nui.
Heoi, mō ngā paipa maitai tapawhā iti, tapawhā rite, me whakaaro ki te pūtoro o ngā kokonga porowhita R ina tatauhia te taumaha. I te nuinga o te wā, kāore te whakamātautau e whakaaro ki te rerekētanga taumaha i waenganui i te 5% ki te 10%, e pā ana ki te utu o ngā kaihanga rauemi angiangi. Nā, me pēhea te tatau i te taumaha kotahi mō ia mita rārangi o te paipa maitai tapawhā rite me te kokonga R?
Hei tatau i te taumaha mō ia roa o te kōtaha, me kimi e tātou te horahanga whakawhiti-wāhanga, kātahi ka whakareatia ki te mātotoru rauemi e rite ana, ā, ka taea te whiwhi i tōna taumaha.
Mō te ngongo tapawhā rite e whakaaturia ana i raro nei, ka taea e tātou te whiwhi i te horahanga whakawhiti-wāhanga A = H*B-(H-2t)*(B-2t) mō te wāhanga katoa mēnā kāore tātou e whai whakaaro ki te pānga o te koki-R.
Kia mōhiotia ko te radius o te kokonga o waho ko R, ka tāpirihia noa te horahanga o te poraka kikorangi, ka tangohia te horahanga o te poraka whero (e whakaaturia ana i te pikitia i raro nei) kia whiwhi ai i te horahanga tuturu o te wāhanga. Ā, mō te nuinga o ngā ngongo tapawhā rite, he rite tonu te pokapū porowhita o ngā kokonga o roto me o waho, nō reira ko te radius kokonga o roto ko r = Rt. I muri i te whakatau i ēnei pūwāhi, ka taea e tātou te whakaputa ngāwari i te tātai horahanga.
Hei tāpiritanga, i roto i te whakatakotoranga "GBT 3094-2012 paipa maitai āhua-makariri", kua hoatu he tātai tatau taumaha kotahi motuhake, he rite tonu hoki tōna mātāpono tatau me taku i kōrero ai i runga ake nei, tirohia te tūtohi e whai ake nei.
Mātakitakihia te tātai, ka kitea ko te uara o R i roto i te whakatakotoranga ka whakatauhia e te matotoru o te pakitara o te paipa maitai, nō reira, ki te kore koe e mōhio ki te uara R motuhake mō te nui, ka taea hoki e koe te tango i te uara e ai ki te whakatakotoranga, arā -
R=1.5 ngā wā o te matotoru o te pakitara ina ≤6mm te matotoru o te pakitara. Ina neke atu i te 6mm te matotoru o te pakitara, R=2 ngā wā o te matotoru o te pakitara
I roto i te mahi, ka taea hoki e tātou te tatau i te taumaha o ngā ngongo tapawhā rite me ngā kokonga porowhita mā te whakamahi i ngā taputapu kei a tātou.
