Mōta Paru Keri Aronga Whakapae
Whakaahuatanga Hua
ERT (Matotoru Rapa Taurite):
He mea tika kia whakarerekētia te āhua o te whare stator, he angiangi, he ōrite te paparanga elastomer stator o te motuka Uniform Thickness downhole. Ko ngā āhuatanga o te motuka downhole ko te poto te roa, te kaha teitei, te hekenga pēhanga teitei, te tere hurihuri iti, te pai o te whakamatao teitei, te whānui o te wera, te whānui ake o te whakamahinga, te hanganga pai ake me te taumaha mama. Ina koa, ka taea e ngā āhuatanga te whakaroa i te ora o te motuka downhole me te whakapai ake i te pai o te keri i roto i te poka hohonu rawa, te poka ahunga me te poka pāmahana teitei.
Ātete ki te paru pāmahana-teitei me te hinu:
He pai te mōta raro-pū mō te pūnaha paru hinu-mahana teitei, teitei. I raro i ngā āhuatanga o te 180°C me te hinu-nui, he teitei ngā reiti pupuri o te kaha kaha, te kaha haehae me ētahi atu āhuatanga o te elastomer stator motuhake. He pai ake te pānga whakamahi o te elastomer ātete-hinu me te nui o te pokanoa i roto i te paru hinu-mahana teitei, teitei.
Ātete ki te waikura:
I muri i te rehu waikura hei hanga i tētahi paninga motuhake, ka pai ake te ātete o te rotor ki te waikura, te horo me te pakū. Ā, he pai te motuka raro-pū mō te wā roa i roto i te wai waikura.
Te Keri Hau:
Ka taea e te keri hau te tiaki i te puna wai, te whakapai ake i te tere o te urunga, te whakapoto i te wā keri, te whakatūpato i te ngaronga o te paru me te hinga o te poka wai, ā, kei te whakamahia whānuitia inaianei. Ko te motuka keri hau e peia ana e te hau, te pahuka me ētahi atu wai pēhi, e whakarato ana i te hiko mō te poka wai, ā, e akiaki ana i te mata kia uru ki te toka. He nui ake ngā whakaritenga hangarau a te motuka keri hau mō te hanganga huihuinga, te hoahoa raina o te stator motuka me ngā whakaritenga whakahaere.
