Ko te tōtara hau nui o te pūmpu hau he tohu maioha mō te raruraru o te pūnaha. Kāore anō tēnei kōkirikiri e kore e noho tōtika ana i te painga o te mahi katoa engari ka taea hoki te whakapōki e te raru ki ngā wāhanga, ā, ka aronga ai te wā roa me ngā utu whakatika. He mea matua nui te whakatika tūmatanui i ngā take takotoranga kia pai ai te pūnaha hau e noho pūmau ai.
Ngā Tākarotanga Whakamātau: Te Āta Kimihia i te Take o te Tōtara o te Pūmpu
- Mātai mō te Hau e Ururu Ana (Te Aeration/Cavitation)
Te te ururunga o te hau ki roto i te horapa hau he take noa. Ka pakaru te incompressibility o te horapa ka taea pea te whai cavitation—ko te hanga me te popo o ngā pōro hau ki roto i te pūmpu. Ko tēnei tikanga ka hangaia ētahi micro-implosions e whakaputangia ai te tōtara, te raru, me te raru ki ngā mata o te pūmpu. Mātai ngā tapa tango, ngā wāhanga hono, me ngā rārangi rekaute horapa mō ngā wāhi rere. Whakaritea kia tino pakari ngā hononga katoa, me te pēpi i raro i te taumata wai kia kaua ai te hau e tango ana.
- Whakamātauria te Tere o te Pampi
Ko te whakaputa pampi ki ngā tere e pēra ake ana i tana whakaritenga hoahoa e arapi ana he kore whakakītanga o ana rūma pampi. Ki te kore e taea e te pampi te tango wai tere pēnei i tana ngākau herehere, ka hua mai te paku parakore me ngā panoni toki, ka hua ai te takirua. Me whakaputa tonu i te pampi ki roto i te tauwae tere e tautohe ana te kaihanga kia whakarite ai i te rere tino māmā, kia kaua ai te wareware māmā.
- Tāria ngā Tikanga Unga o te Pūnaha
Ko te pūnaha hydrauhiki e taraweti ana e whakaputa ana te pampi ki te toki nui rawa, e arapi ana he kore āhua me te takirua. Ko tēnei kōkirikiri e murua ai te maroke me te whakatupua i ngā mōrearea haumaru. Manaakitia ngā taputapu ine toki, me te whakarite kia kaua te mahi e pāngia tonu ai i te mākainga e tautoko ana te pampi. Tirohia ngā tautuhinga vālve herehere, me te rapu i ngā waahanga pouaka, pouaka ranei e āki ai pea i ngā wāhi toki iti.
- Whakamātau i te Viscosity o te Horapa Hiko
Ko te viscosity hē o te horapa e pa tū ana ki te whakaeke o te pamp. Ko te hinu e nui ake ana (te teitei o te viscosity) ka whakaputa pikinga, e muhu ai te pamp ki te tango i te horapa, ā, he iti noa ngā wā i ngā timatanga makariri. Ko te hinu e iti ake ana (te iti o te viscosity) ka pakaru te whakarato i te whakamaroke tika me te pouaka o roto i te pamp, ā, ka piki te urupare me te whakapānga kōhatu-kōhatu. Whakamahia kaua te rahi o te hinu i tohua e te kaihanga taputapu, ā, me whai whakaaro ki ngā panonitanga o te wera mō te wā o te tau.
- Tirohia te Pamp me te Whakaurunga Tō
Ko te whakauru hē, āx specifically ko te wehe ke o te porowhā o te pamp me te porowhā o te motuka tō, ka hoatu kaha anuanu me ngā wāhi poke ki te pamp. Ko tēnei kaha takotoranga he kaha tūturu mō te putangia me te tere ake o te wareware o ngā pāpā me ngā pāpāri. I te wā o te whakauru, whakamahia ngā taputapu tikanga hei tirohia me te whakatika i te wehenga e ai ki ngā whakaritenga hangarau. Me tiakina hoki kia ma, kia kaha ngā mata o te tuunga, ā, kia tika ngā momo hononga.
He Matua Whaiaro te Tiaki
Ko te tiaki whakaritenga te timatanga ki te aukati i ngā tōtoko o te pūmpu. Ko te āhua o ngā rāwekenga mō te whakamātau i te kirihou me te pakaru o te uira, ko ngā tirotiro matua i ngā kīho me ngā parerarua, me te whakarongo ki ngā raru korenoa o te pūmpu. Mā te whakatika pūmau i ēnei raru e mōhiotia ana—te urunga o te hau, te tere, te uta, te tikanga o te karutahi, me te whakauru takotoranga takotoranga—ka taea e koe te wehe i ngā tōtoko nui, te whakanui ake i te whakapono o te punaha, me te roa atu o te wā o ō taputapu hydrauhiko.
