Ko te papu he miihini e kawe ana, e pehi ana ranei i te wai.Ka whakawhitihia te kaha miihini me etahi atu kaha o waho o te kaikawe tuatahi ki te wai, kia piki ake ai te kaha o te wai, te nuinga o te whakamahi ki te kawe i nga wai tae atu ki te wai, te hinu, te waikawa rei, te emulsion, te whakaehunga whakatara me te whakarewa wai, etc.
Ka taea hoki te kawe i te wai, te ranunga hau me te wai kei roto te totoka iri.Ko nga tawhā hangarau o te mahi papu he rere, momi, mahunga, te mana o te rakau, te mana wai, te pai, me era atu. E ai ki nga tikanga mahi rereke ka taea te wehewehe ki te papu displacement pai, te papu vane me etahi atu momo.Puma displacement pai ko te whakamahi o ona huringa rōrahi studio ki te whakawhiti pūngao;Ko te papu Vane ko te whakamahi i te mata hurihuri me te taunekeneke wai ki te whakawhiti i te kaha, kei reira he papu centrifugal, he papu rere axial me te papu rere whakauru me etahi atu momo.
1, mena he iti te he o te papu kia mahara kia kaua e mahi.Mena ka taapirihia te whakakii i te rakau papu i muri i te kakahu, mena ka whakamahi tonu te papu ka turuturu.Ko te paanga tika o tenei ko te nui ake o te whakapaunga hiko motika ka kino te impeller.
2, ki te te papu wai i roto i te whakamahi o te tukanga o te wiri kaha i tenei wa me mutu ki te tirohia he aha te mea te take, te kore ka meinga hoki te reira kino ki te papu.
3, i te wa e pupuhi ana te paera o raro, ka whakamahia e etahi taangata te oneone maroke hei whakakii ki roto i te putorino whakauru, te wai ki te pito o te paera, kaore i te pai te mahi penei.No te mea ka tukuna te oneone maroke ki roto i te putorino wai ka timata te mahi o te papu, ka uru te oneone maroke ki roto i te papu, katahi ka kino te impeller papu me nga peera, kia poto ai te oranga o te papu.Ka pakaru te riu o raro, me mau ki te whakatika, mena he kino, me whakakapi ki te hou.
4, i muri i te whakamahinga o te papu me whakarongo ki te tiaki, penei i te wa e whakamahia ana te papu ki te maka i te wai ki roto i te papu ma, he pai ki te tango i te paipa wai ka horoi ki te wai ma.
5. Me tango ano te riipene i runga i te papu, ka horoi ki te wai ka whakamaroke ki te marama.Kaua e waiho te riipene ki tetahi waahi pouri me te makuku.Ko te riipene o te papu kaua e pokea ki te hinu, kaua e whakahua etahi mea piri ki runga i te riipene.
6, ki te āta tirohia mehemea he kapiti i runga i te impeller, te impeller kua whakaritea i runga i te whanau he wetekina, ki te mea he kapiti me te wewete āhuatanga ki te tiaki wā, ki te he oneone i runga ake i te impeller papu kia hoki kia horoia ake.
