Ko ngā āhuatanga ā-tinana me ā-matū o te reo papu te tūāpapa mō ngā whakataunga hangarau hiri katoa. Ka pā tika te matotoru, ngā taumata pH, te taumaha motuhake, me te pēhanga kohu ki te hanganga kiriata wai me te whakahinuhinu mata. Mēnā ka papuhia ngā wai e tata ana ki tō rātou pēhanga kohu, ka tūpono pea ka mura ki ngā mata hiri, ā, me whakamatao, me whakanui rānei i te pēhanga.

Me whakauru ngā tawhā pēhanga me te pāmahana i ngā awhe mahi noa me ngā āhuatanga whakakorikori mōrahi. He maha ngā wā ka tukuna ngā hiri e ngā papu matū ki ngā pēhanga pouaka whakakī tae atu ki te 25 pae me ngā pāmahana tino nui. Hei tāpiri, ko te nui o te totoka e whakatau ana i te pakeke o te mata me te āhua o te hiri; ko te kukū totoka neke atu i te 5% te taumaha me whai mahere horoi motuhake, hiri paru rānei hei ārai i te keri o te mata me te aukati i te puna.

Te tere o te toki, te whakaritenga o te papu, me te mahere paipa

He nui te pānga o ngā āhuatanga kinematic me ngā āhuatanga hanganga ki te whanaketanga o te hiri. Ko te tere o te toki, mai i te 1,450 ki te 3,600 RPM i roto i ngā papu matū paerewa, e whakatau ana i te tere ā-taha i ngā mata o te hiri. Ko ngā tere teitei ka whakaputa i te wera waku nui, e hiahiatia ana te kawe wera nui ake i roto i ngā rauemi mata kua tohua me ngā mahere whakamatao kua arotauhia.

Ko te whakaritenga o te papu—ahakoa he whakapae, he poutū, he rārangi rānei—ka whakarerekē i te kaha o te whakaputa hau me te whakaheke wai o te rūma hiri. Hei tauira, he ngāwari ngā papu poutū ki te hopu i te hau i te atanga hiri, me ngā whirihoranga whakaputa hau motuhake hei ārai i te rere maroke. I te wā kotahi, me whakauru pai te mahere paipa API 682 kua tīpakohia (pēnei i te Mahere 11 mō te horoi taha, te Mahere 53A rānei mō te wai ārai pēhanga) ki ngā here ā-wāhi me te waipēhi o te papu.

Ngā rauemi mata hiri, ngā elastomers, me ngā wāhanga whakarewa

Ko te hototahitanga o ngā rauemi te mea e whakatau ana i te roa o te ora o te atanga hiri me ngā huānga hiri tuarua. Me taurite te pakeke, te hinu whakahinuhinu, me te koretake o ngā matū i ngā mata hiri tuatahi. Ko te Silicon Carbide (SiC) te paerewa ahumahi nā tōna ātete matū whānui me te tino pai ki te tohatoha wera, ahakoa ka taea te whiriwhiri i te Tungsten Carbide (TC) mō ngā paru tino koi, kāore e waikura.

He rite tonu te hiranga o ngā elastomers tuarua, ā, he maha ngā wā koinei te hononga ngoikore rawa atu i roto i ngā tono matū. Ka tere pea te pirau o ngā fluoroelastomers paerewa (FKM) i roto i ngā whakarewa kaha, me whakahou ake ki ngā perfluoroelastomers (FFKM), e tuku ana i te hototahi matū tata ki te ao whānui, ā, ka taea te tu atu i ngā pāmahana mahi tonu tae atu ki te 320°C. Me ātete hoki ngā wāhanga whakarewa, tae atu ki ngā puna me ngā kara taraiwa, ki te whakaeke waikura, e hiahiatia ana te whakamahi i ngā koranu nikara-teitei pērā i te Hastelloy C-276, te Alloy 20 rānei hei utu mō te maitai kowiri tira 316 paerewa.

Ko ngā hiri mīhini takitahi ka whakamahia i roto i ngā mahi kore-morearea, kore-paitini, ina kore he mōrearea haumaru, he mōrearea taiao rānei te turuturu iti ki te hau. Ka whakawhirinaki noa rātou ki te wai i pupuhihia mō te whakahinuhinu, ā, koinei te otinga tino whai hua mō ngā matū wai kore-kino, ngā whakarewa ngawari rānei.

E hiahiatia ana ngā hiri takirua mō ngā wai tino paitini, ngā wai e puta ai te mate pukupuku, ngā wai pūngāwerewere rānei. Ko ngā hiri takirua kāore i te pēhanga (tandem) e whakarato ana i tētahi paparanga pupuri tārua, ko ngā hiri takirua pēhanga (takirua) e whakamahi ana i tētahi wai ārai i te pēhanga teitei ake i te rūma papu hei whakarite kia kore he tukunga tukanga ki te hau. Ko ngā hiri kātere, e tākai ana i ngā mata hiri, ngā puna, me te pereti repe ki roto i tētahi waeine kotahi kua oti te huihui, he mea tino pai ki ngā whirihoranga takitahi me te takirua nā te mea he tika te whakaritenga me te ngāwari o te tāutanga, ka whakaiti nui i te hapa tangata i te wā tiaki.
