Ina whakatinanahia ki roto i te taiao wai tika me te takai taputapu, ka tukuna e ēnei hiri te pono tino pai me te roa o te wā waenga i waenga i ngā rahunga (MTBF).

Ngā tikanga whakahaere me ngā tono pai rawa atu

He tino pai ngā hiri puna ngaru mō ngā whakamahinga wai ma, kore-whakakoi. He tino whai hua rātou mōngā whare maimoatanga wai, te tukatuka rongoā, me te whakaputa inu kai-papa, ina kore he matūriki taumaha i roto i ngā pāpāho papu. Ko ngā tikanga whakahaere pai ko ngā wai he iti ki te waenga te matotoru hihiri, me te noho tonu i raro i te paepae 500 cP.

I roto i ngā tono hauwaiwai māmā mengā papu whakawhiti matūI te whakahaere i ngā whakarewa, ka ārai te pēhanga mata ōrite i te wehenga mata moroiti e hua ake ai ngā tukunga rere. Mā te kore o ngā totoka taumaha ka mau tonu te ngāwari o te puna ngaru, ka taea ai e ngā mata hiri te whai i te rere iti o te rakau.

Ngā painga o ngā taputapu kiato me te iti o te wāhi tuaka

Ko te painga whakahaere nui rawa atu o ngā hiri puna ngaru ko tōna whai huatanga i roto i ngā taputapu kiato. Ko ngā hoahoa papu hou, inā koa ko ngā papu porotaka hurihuri, ngā papu taputapu, me ngā papu porowhita ANSI poto, he maha ngā wā ka whakamahia he pouaka whakakī tino herea hei whakaiti i te iri o te pou me te whakaiti i te piko.

Mā te hiahia kia 50% te iti iho o te wāhi tuaka i ngā hiri miihini kotahi-koiri tuku iho, ka taea e ngā puna ngaru ngā kaihanga taputapu te hoahoa i ngā toki papu poto ake, pakari ake. Ka whakaitihia e te toki poto ake te ōwehenga L3/D4 (te roa o te toki kua tapahia ki runga i te diameter ki te mana tuawhā), e pā tika ana ki ngā taumata wiri iti ake me te roa o te ora o te peera. Mā tēnei kiato ka māmā ake te whakahou i ngā whakaritenga hiri-rua ki roto i ngā rūma hiri-kotahi paerewa.

Te mahi i whakaritea ki ngā hoahoa hiri tuku iho

Ki te whakaritea ki ngā hoahoa hiri tuku iho, he pai ake te aro turuki i te mata o ngā momo puna ngaru i roto i ngā kōpaki piri. Mā te kōtaha ngaru tonu ka mau tonu te mana whakahaere o te rerekētanga piko, i roto i te ±5% puta noa i te porowhita katoa o te mata hiri. Mā tēnei tohatoha kawenga tika ka ārai i te hanganga o ngā wāhi wera ā-rohe, e puta pinepine ai te pakaru wera i roto i ngā rauemi mata pakarukaru pērā i te silicon carbide.

Hei tāpiritanga, ko te taumaha iti o te puna ngaru ka whakaiti i ngā kaha porotītaha i ngā tere hurihuri teitei (he maha ngā wā ka neke atu i te 3,600 RPM). Mā tēnei pumau ka whakaitihia te whakapōturitanga hihiri, ka whakarite kia noho rite tonu ngā mata hiri tuatahi, ā, kia mau tonu te matotoru o te kiriata wai ki ngā taumata moroiti tino pai.

Ko te āhua ā-tinana o ngā puna ngaru e whakawhāiti ana i tō rātou manawanui ki ngā tawhā mahi tino nui. He tino ngāwari ki te pakaru i roto i ngā wai he nui ngā totoka whakatārewatia katoa (TSS) me ngā paru whakakoi. Hei tāpiri, ko te papu i ngā pāpāho tino matotoru neke atu i te 1,000 cP ka ārai i te kaha o te puna ki te pēhi me te whakaora, ka arahi ki te wehenga o te mata.

He tino mōrearea hoki ngā tino kaha o te pēhanga me te pāmahana. Ko ngā puna ngaru paerewa ka herea ki ngā pēhanga i raro iho i te 300 psi (20 pae). Ka taea e ngā taiao pēhanga teitei te piko, te whakapē rānei i te waea papatahi. Ko ngā rohe pāmahana te tikanga e whakatau ana i ngā elastomers tuarua, engari ko te wera nui (neke atu i te 200°C) me whakamahi i te whakarewa puna motuhake, pērā i te Inconel 718, hei ārai i te ngaronga o te manawa me te whakangā o te puna.

Ngā mōrearea rahunga noa pēnei i te paru me te aukati i te puna

Ko te tikanga tino kitea mō te pakaru o ngā hiri puna ngaru ko te poke o ngā matūriki me te aukati i te puna. Ko ngā āputa whaiti, mai i te tihi ki te tihi o te hoahoa ngaru ka mahi hei mahanga mō ngā paru, ngā wai tioata, me ngā hua piri. Ina uru ngā totoka iri nui atu i te 50 maikorona ki roto i te kōhao puna, ka taea e rātou te piri ki roto i ēnei āputa.

Kia purua, ka ngaro te ngāwari o te puna. Ko tēnei āhuatanga, e mōhiotia ana ko te 'hang-up', ka ārai i te puna ki te pana i te hiri ki mua hei utu mō te pakaru noa, te whakawhānui wera rānei o te pou. Nō reira, ka wehe te hiri, ka hua ake he turuturu wai kino me ngā tūponotanga kino ki te taiao.

Āhea te whiriwhiri i ngā momo hiri rerekē

Me tautuhi e ngā kaihangarau tipu ētahi atu hangarau hiri ina tūtaki ki ngā paru taumaha, ngā matū whakatio, ngā pūmua matotoru rānei. Ko ngā hiri whakarewa taha-whakapiri te mea pai mō ngā mahi pāmahana teitei, whakatio rānei, nā te mea ka whakakorehia e te hoahoa tuwhera-whakapiri ngā āputa whaiti e kohikohi ai ngā totoka.

Mō ngā paru taumaha e kitea ana i roto i ngā ahumahi keri, i ngā ahumahi penupenu me te pepa rānei, ka whakaratohia e ngā hiri puna kotahi-koiri pakari me ngā diameter waea nui te pakari e tika ana. Mā te hanganga tuwhera o te puna koiri taumaha ka taea e ngā matūriki te horoi atu i roto i te wai horoi, ka mau tonu te ngāwari o te puna, ā, ka whakarite kia haere tonu te mata ki te wāhi e piri tonu ai te puna ngaru.
