Te hura i te mea ngaro o te tauwehenga upoko o te pūhiko pehi

I te ao o ngā mīhini ahumahi, ko te centrifugal PūhikoHe mahi nui tā rātou i roto i te whānuitanga o ngā mahi, mai i ngā tipu hinu-matū ki ngā whare whakaputa hiko. Ko tētahi o ngā tawhā matua e whakatau ana i te mahi a tepūwhakapūngao tohangako te tauwehenga upoko. I roto i tēnei tuhinga, ka rukuhia e mātou he aha te tauwehenga upoko, he aha tōna hiranga, me tōna pānga ki te mahi a ēnei mīhini nui.

He aha tonu te Tauwehenga Upoko?

Ko te tauwehenga upoko o te kōpeketia te pūwerorhe rahinga kore-ahu e whakarato ana i ngā māramatanga whai hua ki te mahi a te pūhiko. He ine tēnei i te whanaungatanga i waenga i te pūngao e tukuna ana ki te wai e te Pūhiko Ame te tere o te impeller i tōna diameter o waho. I ngā kupu māmā ake, ka āwhina i ngā kaihangarau me ngā kaiwhakahaere ki te mārama ki te whai huatanga o te hurihanga a te compressor i te pūngao miihini ki te pūngao pēhanga mō te wai e pēhia ana.

Mā te pāngarau, ka tatauhia te tauwehenga upoko (ψ) mā te whakamahi i te tātai: ψ = (gH) / u₂², ko g te whakaterenga nā te kaha ā-papatipu, ko H te upoko o te pūwero (te pūngao mō ia taumaha o te wai), ā, ko u₂ te tere o te pito o te impeller. Mā tēnei tātai ka taea te whakataurite paerewa i te mahi pūwero puta noa i ngā hoahoa me ngā āhuatanga whakahaere rerekē.

He aha te Hiranga o te Tauwehenga Upoko?

He mea tino nui te tauwehenga upoko mō ētahi take. Tuatahi, he mea nui ki te whakatau i te whai huatanga o te pūwero. Ko te tauwehenga upoko teitei ake e tohu ana ka taea e te pūwero te whakatutuki i te pikinga nui ake o te pēhanga mō te tere o te impeller, ko te tikanga he iti ake te pūngao e maumauria ana i roto i te tukanga pēhanga. Ehara i te mea ka whakaitihia ngā utu whakahaere anake engari ka pai ake te taiao o te pūwero mā te whakaiti i te whakapaunga pūngao.

Tuarua, he āwhina i te hoahoa me te whiriwhiri i ngā pūwero hau. Ka taea e ngā kaihangarau te whakamahi i te tauwehenga upoko hei paearu hei whakatairite i ngā tauira pūwero rerekē, me te whiriwhiri i te mea e tino pai ana mō ngā whakaritenga motuhake o tētahi tono motuhake. Hei tauira, i roto i ngā tono e hiahiatia ana he ōwehenga pēhanga teitei, he pai ake pea te pūwero me te tauwehenga upoko teitei ake.

Heoi anō, he pai hoki te tauwehenga upoko mō te matapae i te mahi a te pūwero i raro i ngā āhuatanga whakahaere rerekē. Mā te mārama ki te rerekētanga o te tauwehenga upoko me ngā āhuatanga pēnei i te tere rere, te pāmahana, me te pēhanga, ka taea e ngā kaiwhakahaere te arotau i te mahi a te pūwero kia tino whai hua ai, kia pono ai hoki.

Pānga ki te Mahi a te Pūhiko

He pānga tika tō te tauwehenga upoko ki ngā āhuatanga maha o pūwhakapūngao tohangate mahi. Hei tauira, ka pā ki te pikinga o te pēhanga puta noa i te pūwero. Ko te tikanga o te tauwehenga teitei ake ka taea e te pūwero te whakaputa i te rerekētanga pēhanga nui ake, he mea nui tēnei mō ngā tono pēnei i te kawe hau me te whakamatao.

Ka pā anō hoki ki te pumau o te pūwero. Ko ngā pūwero he tauwehenga upoko kua tautuhia pai, he nui ake te tūponotanga ka mahi pumau i runga i te whānuitanga o ngā tere rere. Nā te mea ka āwhina te tauwehenga upoko ki te pupuri i te taurite tika i waenga i te pēhanga me ngā āhuatanga rere o te pūwero, ka ārai i ngā raruraru pēnei i te ngaru me te kōpiri.

Hei tāpiritanga, ka pā te tauwehenga upoko ki te pakaru me te haehae o ngā wāhanga o te pūwero. Mēnā he nui ake ngā tauwehenga upoko o ngā pūwero e mahi ana, ka nui ake pea te taumahatanga ki te impeller me ētahi atu wāhanga, ka nui ake pea ngā whakaritenga tiaki me te poto ake o te roanga o te ora mēnā kāore e tika te whakahaere.

Whakamutunga

Ko te tauwehenga upoko o te pūwero whakatere he tawhā matua e whai wāhi nui ana ki te whakatau i te mahi, te whai huatanga, me te pono o ēnei mīhini nui. Mā te mārama ki te tikanga o te tauwehenga upoko me tōna pānga ki te mahi a te pūwero whakatere, ka taea e ngā kaihangarau me ngā kaiwhakahaere te whakatau whai whakaaro ina tae mai ki te hoahoa, te whiriwhiri, me te whakahaere i ngā pūwero whakatere. I te mea kei te tipu haere tonu te hiahia mō ngā pūnaha kōpeketanga whai hua me te pono i roto i ngā momo ahumahi, he mea nui te māramatanga hohonu ake ki te tauwehenga upoko hei whakarite i te mahi tino pai o ngā pūwero whakatere i ngā tau e haere ake nei. Nō reira, i te wā e tūtaki ai koe ki tētahi pūwero whakatere, kia mahara ki te hiranga o te tauwehenga upoko me tōna pānga ki te mahi whānui o tēnei mīhini whakamiharo.
