Ko te keeti rerehu rewharewha o raro i te whenua i tukuna mai e to matou kamupene mo tetahi kamupene rino kua tutuki pai.

I whakapumautia e Jinbin valve te ahua mahi me te kaihoko i te timatanga, katahi ka tukuna e te tari hangarau te kaupapa tere me te tika kia rite ki te ahua o te mahi.

Ko tenei kaupapa he keeti rerenga hau hou. Na te raru o te riipene o te riipene taketake me te kore e ngawari ki te whakahou i runga i te turanga o te reera taketake, he mea tika ki te taapiri i tetahi maapiri hou. E rua nga ngongo ngongo o raro o ia oumu katoka, a, me tapiri e ia ngongo ngongo o raro o te whenua he keeti kiriata rewharewha o raro. Whai muri i te taapiri i te kuaha kiriata, ka noho tonu te takirere taketake ki te aratau tuwhera noa. Ko te hiahia o te kaihoko me hangaia ia wahanga o te keeti rerireti rewharewha o raro o te whenua ki te tu ki te huringa o te pāmahana hau rewharewha mai i te pāmahana noa ki te 350 ℃ karekau he pakaru, he piri, he korikori, he turuturu ranei. Ka whakatinanahia hei ≤ 2% te rerenga. Ko te Tari Hangarau a Jinbin e whakatau ana i te rahi o te keeti kiriata rewharewha i runga i te maha o nga whakatuwheratanga o te puera rewharewha me nga tawhā hoahoa o te ngongo ngongo o raro. Ko enei keeti rewharewha rewharewha he mahi hiko rua, he mahi pneumatic rua, he hama taumaha, he wini hiko me te taika rokiroki hau. I te nuinga o te wa ka kati te keeti rerenga hau. Ko te nuinga o nga mahi pneumatically tenei valve. Ki te kore e mahi te taputapu pneumatic, ka taea te whakahaere hiko. Hei whakapumau i te tairongo o te kōpae i te wa e mahi ana, ka hangaia te kōpae kia rua nga kōpae, a ka ngawari ia kōpae me te kore e tami ina hiki ana ki runga me raro. I te wa ano, ka whakatakotoria he kiriata hiri ki roto i te kohao o roto o te anga tinana kia pai ai te hiri o te kōpae me te whakaiti i te wiri o te kōpae i te wa e hiki ana. Hei aukati i te rere o te rewharewha o te kopae i te wa e hiki ana, me whakauru he hiri ki runga ake o te anga tinana.

Ka taea e te keeti kiriata rewharewha te whakaoti i te raru o te whakahaere tere o te paipa hau rewharewha mena he aitua, te whakarite i te wa tika me te pai o te maimoatanga o nga raru aitua, me te karo i nga mate ohaoha nui ake; Ka taea hoki te whakaoti i te raru o te whakahaere a-ringa i te tuunga o te keeti kiriata rewharewha, me te tino whakaiti i te kaha o nga kaimahi.
