Tepapu poutūI te tīmatanga o te tekau tau atu i 1920, i hurihia te umanga papu e te motuka hiko mā te whakahohe i te whakapiri i ngā motuka hiko ki te tihi o te papu, ā, i hua ake he pānga nui. Nā tēnei i māmā ake te tukanga tāutanga, ā, i whakaitihia ngā utu nā te iti o ngā wāhanga e hiahiatia ana. I piki ake te whai huatanga o ngā motuka papu mā te 30%, ā, nā te āhua motuhake o ngā motuka papu poutū i roa ake ai te pakari me te pono ki te whakataurite ki ō rātou hoa whakapae.
Ko ngā motuka papu poutū ka whakarōpūtia i runga i te momo o te rakau, he mea tuwhera, he mea totoka rānei.
Papu poutū kōhao (VHS)He maha ngā rerekētanga o te hoahoa me te whakamahinga o ngā motuka me ngā motuka papu poutū totoka (VSS). Anei ētahi o ngā rerekētanga matua:
1. Hoahoa o te pou:
-Ngā motuka papu VHShe pou kau, e āhei ai te pou papu ki te haere mā roto i te motuka hei hononga tika ki te impeller. Mā tēnei hoahoa ka kore e hiahiatia he hononga motuhake, ā, ka whakaitihia te roa katoa o te huihuinga papu-motopaika.
-Ngā motuka papu VSShe pou totoka e toro atu ana mai i te mōta ki te impeller. Ko te toronga o te pou he ara kī porowhita hei tuku i te pana papu me te ara kī radial hei whakawhiti i te taipana. Ko te hononga pito o raro i waenga i te mōta papu me te pou papu ka kitea noa i roto i ngā tāke me ngā papu papaku, he rerekē ki ngā mahi poka hohonu.
2. Taupānga:
- E whakamahia whānuitia ana ngā motuka papu VHS i roto i ngā poka hohonu me ngā papu ruku wai, ina toro atu te rakau papu ki roto i te puna, i te awa rānei.
- He maha ngā wā ka whakamahia ngā motuka papu VSS i ngā mahi kāore e hiahiatia kia toro atu te rakau papu ki roto i te puna, i te awa rānei, pērā i ngā papu raina-roto, i ngā mahi rānei kei runga ake i te taumata wai te papu.
3. Te Tiaki:
- Tērā pea he māmā ake te tiaki me te mahi i ngā motuka papu VHS nā te hononga tika i waenga i te motuka me te pou papu. Heoi, he uaua ake te uru atu ki te motuka mō te tiaki nā te mea kei roto i te puna, i te awa rānei.
- Tērā pea me nui ake te tiaki i te hononga i waenga i te motuka me te pou papu mō ngā motuka papu VSS, engari he māmā ake pea te uru atu ki te motuka tonu hei mahi.
Mō ngā Mōta Poutū Kore-ā-Waha: He aha ngā Mōta Kore-ā-Waha?
Kua hangaia ngā motuka poutū tuwhera (VHS) mō ngā tono motuhake ina toro atu te rakau papu ki roto i te puna, i te awa rānei.
I te tīmatanga, i whakamahia ngā papu i runga ake i te whenua mō te whakamakuku i ngā āhuarangi maroke engari he pai mō te ahuwhenua, pērā i California. He whirihoranga taputapu koki-matau ēnei papu, ā, i whakakahangia e ngā miihini tahu ā-roto. Nā te whakaurunga o ngā motuka hiko i runga i ngā papu i whakakorea te hiahia mō te pouaka miihini hei whakarato i te taipana me ngā peera pana o waho mō te pana papu tāpiri. Nā tēnei whakaiti i ngā taputapu i hua ake ai he utu iti iho, he rahi iti ake, he ngāwari ake te tāutanga, me te iti ake o ngā wāhanga. He tata ki te 30% te pai ake o te mahi a ngā motuka papu poutū i ngā motuka whakapae, ā, he mea hanga motuhake mō te mahi, e tuku ana i te roa me te pono ake mō ngā tono papu. Hei tāpiri, kua hangaia kia tu atu ki ngā momo āhuatanga taiao. Nō reira, i taea e te ahuwhenua i California te tupu i raro i ēnei āhuatanga.
Me whiriwhiri e au he mōta poro totoka, he mōta poro kau rānei hei mahi i te mahi?
Ko te whiriwhiri i te mōta poro totoka tika, i te mōta poro kau rānei mō tētahi mahi motuhake, ka whakawhirinaki ki ngā whakaritenga o te tono me ngā āhuatanga taiao. Ko ngā mōta poro totoka te tikanga e whakamahia ana i ngā tono kāore e hiahiatia kia toro atu te poro papu ki roto i te puna, i te awa rānei, pērā i ngā papu raina-roto, i ngā tāutanga i runga ake i te whenua rānei. I tētahi atu taha, he pai ngā mōta poro kau mō ngā tono puna hohonu me ngā papu ruku, ina toro atu te poro papu ki roto i te puna, i te awa rānei.
Haunga ngā whakaritenga paerewa pēnei i te hōiho, te tere, te āputa, te mana whakauru, me te rahi anga e pā ana ki ngā motuka whakapūmau katoa, he whakaritenga pana motuhake anō hoki ā ngā motuka poutū poutū (VHS). Me nui ake te kaha pana o te motuka i ngā kaha tuaka katoa ka tūtaki ki a ia, tae atu ki te taumaha o te rotor, te pou o te raina papu me te impeller, me ngā kaha hihiri e hiahiatia ana hei hiki i te wai ki te mata.
E toru ngā kōwhiringa mō te pana: ngā motuka pana noa, ngā motuka pana waenga, me ngā motuka pana teitei. E kiia ana he motuka pana noa te motuka whakapae, ā, he pai mō ngā tono whānui ina iti te pana o waho e pā ana ki te peera motuka.
Ko te mōta pana waenga, e mōhiotia ana ko te mōta papu raina-roto, he mea hanga mō ngā mahi motuhake, ā, e kiia ana he mōta kaupapa motuhake. Ka whakanohoia tika ngā impeller ki runga i te rakau mōta, ā, ko te whāriki pana kei raro i te nuinga o te wā hei ārai i te tipu wera o te rotor kei pā ki ngā āputa o te impeller. Me whai manawanui ki ngā rakau mōta me ngā ātete oma flange kia piri, nā te mea ka whakawhirinaki te mahi a te impeller ki te manawanui tata ki te whare papu.
Ka taea e te kaihanga te whakarite i tētahi mōtini pana teitei, ā, he maha ngā pana e tukuna ana ki te 100%, 175%, 300% rānei, me te whāriki pana e tata ana ki te tihi.
Mena kei te hiahia āwhina koe ki te whiriwhiri i te mōta tika mō tāu mahi, kaua e mangere ki te whakapā atu ki tētahi tohunga i Tkflo. E harikoa ana mātou ki te whakautu i ō pātai mō te whiriwhiri i te mōta poutū tika mō ō hiahia.
He aha ngā tono mō teNgā Papu Tīpene Poutū?
Ko ngā whakamahinga o ngā Papu Pūwero Poutū he maha ngā whakamahinga i roto i te tuku wai, te whakamakuku, ngā tukanga ahumahi, me ngā pūnaha wai ā-tāone. Ka whakamahia ēnei mō te whakamakuku ahuwhenua, te whakawhiti wai i roto i ngā pūnaha tuku wai ā-tāone, me ngā tukanga ahumahi pēnei i te tohanga wai whakamatao me te maimoatanga waipara.
Ko te papu tāpoi poutū (VTP) he momo papu hiko hurihuri kei roto he impeller rere radial, he impeller rere radial kua whakapaitia rānei. He maha ngā wāhanga o ēnei papu, he maha ngā taumata impeller kei roto i te huihuinga peihana, ā, ka taea te whakarōpū hei papu poka hohonu, hei papu huinga poto rānei.
He mea tāuta noa te tāwhana poka hohonu ki roto i tētahi poka kua keria, me te impeller wāhanga tuatahi kei raro i te taumata wai o te papu. He mea whakapūmau-ake ēnei papu, he maha ngā wāhanga o te wā, ā, e whakamahia ana mō te kawe wai. Ko tā rātou whakamahinga matua ko te kawe i te wai mai i ngā poka hohonu ki te mata.
Ka haria te wai e ēnei papu ki ngā tipu maimoatanga, ki ngā pūnaha whakamakuku, me ngā taputapu whare. He rite tonu te mahi a ngā papu poto-taumata ki ngā papu poka hohonu, e mahi ana i ngā puna wai pāpaku me te hohonutanga mōrahi tata ki te 40 putu.
Ka taea te tāuta i te papu VTP ki roto i tētahi oko momi, i raro rānei i te taumata whenua hei whakanui ake i ngā pane momi mō te impeller wāhanga tuatahi. He maha ngā whakamahinga o ēnei papu hei papu whakakaha, hei ētahi atu whakamahinga rānei e taea ai te uru atu ki tētahi pane momi pai kupenga iti (NPSH).
Nā te kaha o ēnei wai ki te whakahaere i ngā rerenga wai teitei, me te mahi tika i roto i ngā taiao uaua, he mea e tika ana mō te whānuitanga o ngā mahi, tae atu ki ērā e hiahia ana kia tukuna te wai me te pēhanga teitei.
