He aha te rerekētanga i waenga i ngā papu momi ā-roto me ngā papu momi mutunga?
Ngā papu ā-rotomepapu momi mutungae rua ngā momo papu toremi e whakamahia whānuitia ana i roto i ngā momo mahi, ā, he rerekē te nuinga o ēnei i roto i ō rātou hoahoa, tāutanga, me ngā āhuatanga whakahaere. Anei ngā rerekētanga matua i waenga i ngā mea e rua:
1. Hoahoa me te Whirihoranga:
Ngā Papu Ā-roto:
He rārangi tika te hanganga o ngā papu ā-roto, arā, ko te tomokanga me te putanga. Mā tēnei whirihoranga ka taea te tāuta kiato, kia pai ai mō ngā mahi he iti te wāhi.
He porotaka te anga papu, ā, ka whakanohoia tika te impeller ki runga i te rakau motuka.
Ngā Papu Momi Mutunga:
Ko te hoahoa o ngā papu momi pito ko te tomo o te wai ki roto i te papu mai i tetahi pito (te taha momi) ka puta mai i runga (te taha tuku). He hoahoa tuku iho ake tēnei, ā, e whakamahia whānuitia ana i roto i ngā mahi ahumahi maha.
He rite te āhua o te anga papu ki te volute, e āwhina ana ki te huri i te pūngao nekeneke o te wai hei pēhanga.
2. Tāutanga:
Ngā Papu Ā-roto:
He māmā ake te tāuta i ngā papu ā-roto i ngā wāhi kuiti, ā, ka taea te whakairi tika ki runga i ngā pūnaha paipa me te kore e hiahiatia he hanganga tautoko tāpiri.
He maha ngā wā ka whakamahia ēnei i roto i ngā tono e herea ana te wāhi, pērā i ngā pūnaha HVAC.
Ngā Papu Momi Mutunga:
He nui ake te wāhi e hiahiatia ana mō te tāutanga o ngā papu momi mutunga nā te mea he nui ake te tapuwae me te hiahia mō ngā tautoko paipa tāpiri.
He mea noa ēnei hei whakamahi mā ngā tono e hiahiatia ana he nui ake te rere me te pēhanga.
3. Mahi:
Ngā Papu Ā-roto:
He pai ake te whai huatanga o ngā papu ā-roto i ngā tere rere iti iho, ā, he pai hoki mō ngā tono e hiahia ana kia rere tonu me te iti o ngā rerekētanga pehanga.
He maha ngā wā e whakamahia ana ēnei i roto i ngā pūnaha he pumau tonu te tere rere.
Ngā Papu Momi Mutunga:
Ka taea e ngā papu momi mutunga te tu atu i ngā tere rere me ngā pēhanga teitei ake, kia pai ai mō ngā tono whānui ake, tae atu ki te tuku wai, te whakamakuku, me ngā tukanga ahumahi.
He maha ake ngā āhuatanga mahi o ēnei, ā, ka taea te hanga mō ngā āhuatanga whakahaere rerekē.
4. Te Tiaki:
Ngā Papu Ā-roto:
He māmā ake te tiaki nā te hoahoa kiato, engari he iti pea te urunga atu ki te impeller i runga i te tāutanga.
He iti ake ngā wāhanga o ēnei mea i te nuinga o te wā, ā, ka taea te whakaiti i ngā mahi tiaki.
Ngā Papu Momi Mutunga:
Tērā pea ka uaua ake te tiaki nā te mea he nui ake te rahi me te hiahia ki te momotu i ngā paipa kia uru atu ai ki te impeller me ētahi atu wāhanga o roto.
Tērā pea me nui ake ngā mahi tiaki e hiahiatia ana nā te nui ake o ngā ahotea whakahaere.
5. Ngā tono:
Ngā Papu Ā-roto:
E whakamahia whānuitia ana i roto i ngā pūnaha HVAC, te tohanga wai, me ētahi atu tono he iti te wāhi me te taurite o ngā tere rere.
Ngā Papu Momi Mutunga:
E whakamahia whānuitia ana i roto i te tuku wai, te whakamakuku wai, ngā pūnaha tiaki ahi, me ngā tono ahumahi e hiahiatia ana he tere rere me he pēhanga teitei ake.
Papu Momi Mutunga Vs Papu Momi Takirua
Ko te hoahoa o ngā papu mimi mutunga-mīmi ka uru te wai ki roto i te impeller mai i te pito kotahi anake, ko ngā papu mimi takirua ia ka taea te uru te wai ki roto i te impeller mai i ngā pito e rua, e rua ngā putanga.
Papu Momi Mutunga
Ko te papu momi mutunga he momo papu tohanga e tohuhia ana e tōna putanga momi kotahi kei tetahi pito o te anga papu. I roto i tēnei hoahoa, ka uru te wai ki te papu mā te putanga momi, ka rere ki roto i te impeller, kātahi ka tukuna i te koki matau ki te raina momi. He mea whakamahi noa tēnei whirihoranga i roto i ngā tono maha, tae atu ki te tuku wai, te whakamakuku, me ngā pūnaha HVAC. E mōhiotia ana ngā papu momi mutunga mō tō rātou māmā, te kiato, me te whai hua o te utu, e waiho ana hei whiringa rongonui mō te whakahaere i ngā wai ma, i ngā wai kua poke paku rānei. Heoi, he iti noa iho ō rātou kaha rere, ā, me nui ake pea te Upoko Momi Pai Kupenga (NPSH) hei karo i te pirau.
He rerekē, he rua ngā putanga momi o te papu momi takirua, e āhei ai te wai ki te tomo ki te impeller mai i ngā taha e rua. Mā tēnei hoahoa ka taurite ngā kaha waipēhi e pā ana ki te impeller, ka taea ai e te papu te whakahaere i ngā tere rere nui ake me te whai hua ake. He maha ngā wā ka whakamahia ngā papu momi takirua i roto i ngā tono nui pēnei i ngā tipu maimoatanga wai, te whakaputa hiko, me ngā tukanga ahumahi e hiahiatia ana te kaha rere nui. He painga ēnei nā te mea ka taea e rātou te whakaiti i te pana axial ki runga i te impeller, ka roa ake te ora mahi me te whakaiti i te kakahu. Heoi, ko te hoahoa uaua ake o ngā papu momi takirua ka hua ake he utu tīmatanga me ngā whakaritenga tiaki teitei ake, me te tapuwae nui ake ki te whakataurite ki ngā papu momi mutunga.
Ko ngā papu tauira ASN me ASNV he papu torengi takirua wāhanga-kotahi mō te momi takirua, ā, he mea whakamahi, he mea kawe wai rānei mō ngā mahi wai, te tohanga hauhautanga, te hanga whare, te whakamakuku whenua, te teihana papu rerenga wai, te teihana hiko, te pūnaha tuku wai ahumahi, te pūnaha tinei ahi, te hanga kaipuke me ērā atu.
