Ngā Tohu Whakatūpato Moata i mua i te Rahunga o te Hiri Mīhini i roto i ngā Papu Ahumahi

He aha te Hiranga o ngā Tohu Whakatūpato mō te Hiri Mīhini Moata

I roto i ngā pūnaha whakahaere wai ahumahi, ko ngā hiri miihini te ārai matua i waenga i te pou hurihuri me te anga papu tūmau. Ko tō rātou mana whakahaere e tohu tika ana i te pono, te haumaru, me te tutuki i te taiao o te wāhanga papu katoa. I roto i ngā taiao nui te tūponotanga pēnei i te tukatuka warowaihā, te hanga matū, me te whakaputa hiko, ka whakahaerehia te mahi hiri e ngā tawhā tino pakari, e piri ana ki ngā paerewa pēnei i te API 682, e whakahau ana kia iti rawa te 25,000 hāora o te mahi tonu me te kore e hiahiatia he tiaki.

Ahakoa ēnei paerewa hoahoa pakari, ko ngā hiri miihini tonu tētahi o ngā wāhi tino maha o te rahunga i roto i ngā papu tohanga, e 65% ki te 70% o ngā wawaotanga tiaki papu katoa. Ko te mōhio ki ngā tohu whakatūpato wawe o te pakaru o te hiri ehara i te mea he mahi tiaki pai noa iho; he whakahau whakahaere nui hoki. Mā te wawao i mua i te takahi a te hiri i ōna paepae whakahaere ka ārai i ngā pekapeka miihini iti kei piki haere ki ngā rahunga taputapu kino.

Te mahi a te hiri miihini i roto i ngā taputapu ahumahi

I te taumata taketake, heka ārai te hiri miihini i te turuturu waimā te pupuri i tētahi āputa moroiti, tino whakahaeretia i waenganui i ngā mata e rua tino papatahi: he mowhiti tuatahi hurihuri me tētahi mowhiti hononga tūmau. Ka herea ēnei mata ki tētahi ātete papatahi o te 2 ki te 3 ngā whitiki mārama, e rite ana ki te 11.6 ki te 17.4 maikoroni. Ka nekehia he kiriata wai angiangi—i waenganui i te 0.5 me te 1.5 maikoroni te matotoru—i waenganui i ēnei mata hei whakarato hinu me te whakamatao e tika ana.

Haunga ngā mata hiri tuatahi, ka whakawhirinaki te huihuinga ki ngā hiri pūmau tuarua, pērā i ngā mowhiti-O elastomeric, ngā poro karāhe ngāwari rānei, hei ārai i te turuturu i te taha o te pou me te anga. Ko ngā huānga utaina ā-mīhini, tae atu kipuna koiri kotahi, ngā puna maha, ngā pupuhi whakarewa whakarewa rānei, ka whakamahia te kaha tuaka tonu hei pupuri i ngā mata hiri kia kati tonu i ngā huringa pēhanga hihiri. Me urutau ēnei wāhanga ki ngā nekehanga poutū tuaka me te porowhita moroiti i te wā e whakahaere ana i ngā pēhanga wai ka neke ake i te 1,000 PSI (69 pae) i ngā tono nui.

Ngā tūponotanga o te kore aro ki te pirau wawe o te hiri

Mā te kore e aro ki ngā tohu tuatahi o te pirau o te hiri ka puta he kawenga nui ki te mahi me te taiao. Ina pakaru te kiriata wai moroiti, ina pakaru rānei te mata o te hiri, ka puta he wera nui ā-rohe nā te waku. Ka taea e tēnei pikinga wera te whakapakeke, te pakaru, te puta rānei o ngā hiri tuarua elastomeric, ka tere te ngaro o te pupuri. I roto i ngā tono e whakahaere ana i ngā matū waro mimiti (VOC), ka puta he tukunga kino ka tere te neke atu i te paepae 500 ppm a te EPA mō ngā tukunga rere.

Hei tāpiri atu, ko te pakaru o te hiri kāore i te tirotirohia ka huri hei kino ā-tinana tuarua. Mā te hiri kua pakaru ka taea e te wai tukanga te heke i te taha o te pou, ka poke te whare peera. E whakaatu ana ngā rangahau ko te poke o te wai tukanga tae noa ki te 0.002% i roto i te hinu whakahinuhinu peera ka taea te whakaiti i te roa o te oranga o te peera tae atu ki te 48%. Mena ka rahua te peera, ka whakangaromia e te piko o te pou ngā wāhanga hiri e toe ana, ka kino pea te anga papu me te impeller, ka nui haere te whānuitanga o te whakatikatika.

Me pēhea te whakaiti i te wā kore mahi me te utu e te kitenga wawe

Mā te kimi matatau i te pakaru o te hiri mīhini ka tino whakarerekē i te āhua ōhanga o te tiaki papu. Mā te whakakapi i te hiri mīhini i runga i te wā kua whakaritea ka taea e ngā tīma hoko te kimi wāhanga me te kore e tere te utu, ā, ka taea hoki e ngā mahi te huri ki ngā taputapu tūmatanui me te kore e whakararuraru i te rere o te whakaputa. Ko te whakakapinga hiri kātere kua whakaritea mō te papu tukanga ANSI paerewa he tikanga ka puta he utu tika mai i te $1,500 ki te $3,500, ā, e whā ki te ono hāora te roa o te mahi.

I tetahi atu taha, ka puta he aukati ohorere i te wā e kore ai e mahi, ā, ka puta he whiu pūtea nui. I roto i tētahi tukanga matū hinu tonu, ka taea e te motuhanga papu kore i whakamaheretia te hua o ngā utu whakaputa mai i te $10,000 ki te neke atu i te $100,000 ia hāora. Mā te whakamahi i te kitenga wawe, ka taea e ngā kaihangarau pono te neke atu i te tinei ahi tauhohe ki te tiaki matapae, ka takirua te Wā Waenga i waenganui i ngā Rahunga (MTBF) me te whakaiti i ngā utu tiaki katoa o te huringa ora mā te 30% ki te 40% e tata ana.

Ngā Āhuatanga Tukanga e Ārahi Ana ki te Rahunga o te Hiri

Kāore e rahua ngā hiri mīhini i te takitahi; ko te pirau o ngā hiri he tohu tonu nō ngā āhuatanga kino o te tukanga, nō ngā ngoikoretanga pūnaha rānei o te mīhini. Kua hangaia te hiri kia mahi i roto i tētahi takai motuhake o te pēhanga, te pāmahana, me te āhua wai. Ina kotiti ke te tukanga ki tua atu i ēnei rohe hangarau, ka pakaru te taurite ngawari o te kiriata wai, ka tere ai te pakaru.

Ko te mārama ki ngā taumahatanga mahi motuhake e whakaeke ana i ngā hiri mīhini te taahiraa tuatahi ki te tautuhi i te pakaru wawe. Me aroturuki tonu e ngā kaihangarau pono te pumau o te waipēhi, te hanganga wai, me te whakaritenga mīhini kia mau tonu ai te taiao hiri mō te mahi roa.

Te kore pumau o te pēhanga, te rere maroke, me te cavitation

Ko te kore pumau o te waipēhi tetahi o ngā tino take o te kino o te mata o te hiri. Ina mahi te papu i tawhiti atu i tōna Pūwāhi Pai Rawa (BEP), ka pāngia e ngā kaha radial me te axial kāore i te taurite, ka puta te piko o te toki, ka akiaki i ngā mata o te hiri kia tuwhera, kia kati tere. Mena ka heke te Upoko Momi Pai Kupenga e wātea ana (NPSHa) ki raro i te tawhā e hiahiatia ana (NPSHr), ka puta te cavitation. Ko te pahūtanga o ngā mirumiru kohu ka puta he ngaru ru e pakaru ai ngā mata o te hiri waro, silicon carbide rānei.

He rite tonu te whakangaromanga o te rere maroke. Ka puta tēnei ina ngaro te pūngao o te papu, ina mimiti rānei te wai tukanga i waenga i ngā mata hiri nā te korenga o ngā tawhā pēhanga mamaoa. Ki te kore te kiriata wai whakahinuhinu, ka piki ake te tauwehenga o te waku. Ka taea e te pāmahana o te mata te piki ake i te 150°C (300°F) i roto i te 30 ki te 60 hēkona o te rere maroke, ka puta te tirotiro wera—he whatunga o ngā kapiti porowhita moroiti i runga i ngā mata hiri e mahi ana pērā i ngā taputapu tapahi ki te mowhiti hoariri.

Ngā wai whakakoi, whakatioata, waikura rānei

He nui te pānga o ngā āhuatanga ā-tinana me ngā āhuatanga matū o te pāpāho papu ki te roa o te ora o te hiri. Ko ngā paru whakakoi he nui ake i te 10% te taumaha o te matū totoka, me whakamahi i ngā huinga mata-mārō motuhake, pērā i te silicon carbide me te tungsten carbide, hei ārai i te keri whakakoi. Mena kei roto i te wai ngā matū totoka rewa ka tioata ina pā ki te hau, ka taea e ngā tioata hua te tākai ki roto i ngā riu O-ringi, ka whakaroa te hiri, ka ārai hoki i ngā puna ki te kati i ngā mata hiri.

Ka whakaekea e ngā wai waikura te mahi whakarewa o ngā wāhanga hiri. Mā te whiriwhiringa rauemi hē ka arahi pea ki te pakaru o te waikura i roto i ngā pupuhi, i ngā puna rānei o te maitai kore waikura 316 nā te ahotea pūhaumāota. Hei tāpiri, mā te kore hototahi matū ki ngā mowhiti-O elastomeric ka pupuhi pea mā te 20% ki te 30% o tō rātou rahinga taketake, ka whakaiti rānei, ka pakarukaru, ka whakangaro i te arai hiri tuarua.

Ngā take tāutanga, whakaritenga, me te whakahinuhinu

Ahakoa te mea tino pakarika pakaru wawe te hiri miihinimēnā kua tāutahia ki runga i ngā taputapu ngoikore te hanganga. E kī ana ngā aratohu API 682 kaua te rere o te porowhita radial e neke ake i te 0.002 inihi (0.05 mm) te Pānui Tohu Katoa (TIR) ​​i te rūma hiri. Ko te nui o te rere, he maha ngā wā ka puta mai i ngā poro piko, i ngā peera pakaru rānei, ka akiaki i ngā wāhanga hiri kia huri haere i ia hurihanga, ka arahi ki te pakaru o te ngenge o te pupuhi whakarewa, o ngā puna rānei.

Ko te taumahatanga o ngā paipa tētahi atu take huna. Ina herea ngā paipa momi, ngā paipa tuku rānei ki ngā pā o te papu me te kore he tautoko tika, ka whakapōturitia te anga o te papu e te taumahatanga miihini. Ka hē te tūnga o te rūma hiri e pā ana ki te rakau hurihuri. Hei tāpiri, ko te korenga o te hinu whakahinuhinu o ngā peera papu ka whakanui ake i te wiri miihini, ka tukuna tika ki ngā mata hiri, ka tere ake te pakaru me te pakaru.

Ngā Tohu Ka Kitea o te Kino o te Kekeno

Nā te mea kei roto i te whare papu ngā hiri ā-ringa, kāore e taea e ngā kaiwhakahaere te tirotiro ā-kanohi i ngā mata hiri i te wā e whakahaerehia ana. Heoi, ko te pakaru o ngā wāhanga o roto ka puta he tohu pono mai i waho. Mā te whakatū i ngā tūāpapa tika mō te mahi noa, ka taea e ngā tīma tiaki te tautuhi i ngā āhuatanga ā-tinana ngaro o te pakaru o te hiri i mua noa atu i te pakaru katoa.

Ko te aroturuki i ēnei tohu ka kitea me whakamahi i te huinga o ngā huringa a te kaiwhakahaere auau, ngā raraunga pūoko aunoa, me te māramatanga mārama ki ngā paepae mahi e whakaaetia ana. Ko ngā huringa o ngā reiti turuturu, ngā waitohu oro, me ngā whanonga pūnaha āwhina hei tohu matua mō te pakaru e tū mai nei.

Te turuturu i tua atu i te tangi hiri noa

He whakaaro hē noa iho tēnei, arā, kāore he turuturu o ngā hiri miihini. Hei pupuri i te kiriata wai whakahinuhinu, me whiti te nui o te wai i ngā mata o te hiri. I roto i te hiri hauora, ka mimiti tēnei wai ina tae ki te taha hauātea, ā, ka kore e kitea te turuturu (he iti iho i te 3 karamu ia hāora mō ngā warowaihā māmā). He tohu kino tonu te turuturu o te wai e kitea ana mai i te repe hiri.

I te aromatawai i te turuturu, me ine te tere o te rerenga hei whakatau i te kaha o te pakaru. Ko te nekehanga mai i te repe maroke ki te tangi puhoi (1 ki te 5 pata ia meneti) e tohu ana i te pakaru tuatahi o te mata, i te pakaru rānei o te mowhiti-O. Ko te maturuturu tonu, te rere tonu rānei e tohu ana i te ngaronga katoa o te pa ki te mata, i te pakaru rānei o te hiri tuarua.

Ngā huringa o te wiri, te haruru, te wera, me te kukume hiko

He maha ngā wā ka whakarerekētia ngā tohu oro me te wiri o te papu e ngā āhuatanga rerekē o te mīhini i ngā mata o te hiri. Ko te haruru nui o te tangi, te haruru "pakū" rānei e puta mai ana i te rūma hiri e tohu ana i te mimiti o te wai, te rere maroke rānei. I te mirimiritanga o te mata o te hiri me te kore e tika te hinu whakahinuhinu, ka akiakihia te motuka hiko e te pikinga o te waku kia nui ake te iahiko. Ko te pikinga tonu o te amperage o te motuka mai i te 5% ki te 10%, me te kore he huringa o te rere, o te hiahia rānei ki te pane, he maha ngā wā ka tohu i te waku nui o te mata o te hiri.

Mā te tātari wiri ka mārama ake te āhua. Ahakoa ko ngā wiri auau-iti (1X, 2X rānei te tere oma) e tohu ana i te kore taurite, i te kore rānei o te tūnga tika, ka puta he tukunga oro auau-teitei nā te kino o te mata hiri. Hei tāpiri, ka puta he wera i te waku nui rawa. Mēnā ka whakaatuhia e ngā matawai wera he teitei ake te pāmahana o te repe hiri i te anga papu e karapoti ana i te 15°C ki te 20°C (27°F ki te 36°F) i te anga papu e karapoti ana, tera pea kua ngoikore te kiriata wai, ā, kei te pā tika ngā mata ki te miihini.

Horoia, tinei, wai ārai, me te hiri i ngā hapa o te kohua

Mōhiri miihini takirua, ko ngā pūnaha wai horoi, wai tinei, wai ārai rānei (hei tauira, ngā Mahere API 52, 53A/B/C, 54 rānei) e mahi ana hei pūnaha tautoko ora me te matapihi tātaritanga matua. I roto i tētahi pūnaha ārai pēhanga Mahere API 53A, ka puritia te wai ārai ki te pēhanga 1.5 ki te 2.0 pae (22 ki te 29 PSI) teitei ake i te pēhanga o te rūma hiri. Tērā pea ka ngaro i tētahi pūnaha hauora te nui o te wai ārai mō tētahi meneti i roto i te marama.

Mena me whakakī anō e ngā kaiwhakahaere te ipu hiri i ngā wā maha atu i te kotahi i te wiki, ki te heke rānei te pēhanga o te pūnaha ki runga ake i te 0.5 pae (7.2 PSI) i roto i te wā 24-hāora, ka raru ngā mata hiri o roto, o waho rānei. I tētahi atu taha, i roto i te pūnaha API Plan 52 kāore he pēhanga, ko te pikinga ohorere o te taumata wai o te ipu hiri, te pikinga tere rānei o te ine pēhanga o te ipu e tohu ana kua rahua te hiri o roto, ka taea ai e te wai tukatuka pēhanga teitei te waipuke i te pūnaha ārai.

Me pēhea te tātaritanga i ngā tohu whakatūpato

Kia kitea he tohu whakatūpato, me huri ngā tīma tiaki me te pono mai i te tirotiro ki te tātaritanga. Mā te tātaritanga tika ka ārai i te hapa noa o te whakakapi i te hiri pakaru me te kore e aro ki te raruraru pūnaha matua, ka arahi tonu ki ngā pakaru.

Ko te tika o te tātaritanga e whakawhirinaki ana ki te hono i ngā tohu ā-tinana ki ngā raraunga tukanga me ngā tuhinga tiaki o mua. Mā te whakarōpū i ēnei raraunga, ka taea e ngā kaihangarau te wehewehe mēnā he āhuatanga ā-pūkaha, ā-whakahaere, ā-matū rānei te pūtake.

Whakatauritehia ngā tohu ki ngā pūtake pea

Ko te taahiraa tuatahi i roto i te tātaritanga ko te mahere i ngā tohu ā-tinana kua kitea ki ō rātou momo rahunga tino pea. Mā tēnei whakatau arorau ka taea e ngā tīma te whakarite i ngā wāhanga whakakapinga tika me te aro atu ki ngā take pūnaha āwhina i mua i te tango i te papu. Hei tauira, mēnā kei te turuturu te hiri, ā, ka waiho he puranga nui o te puehu waro pango pai huri noa i te repe, ko te tātaritanga matua ko te rere maroke nui o te mata waro.

Waihoki, ki te puta he turuturu nui i roto i te hiri, ā, ka memeha haere i a ia anō mō ​​te wā poto, ko te take pea ko te iri o te mowhiti-O nā te wiri, te tioata rānei, kaua ko te pakaru o ngā mata o te hiri.

Whakamahia te wiri, te whakamahana, me te tukatuka i ngā raraunga au

Mā ngā hangarau aroturuki āhua matatau ka whakaratohia ngā raraunga tauanga e hiahiatia ana hei whakaū i ngā whakapae tātaritanga. Ka taea e te takai wiri auau-teitei, pērā i te hangarau PeakVue, te wehe i ngā ngaru ahotea motuhake i puta mai i te pānga o te mata hiri moroiti, ka wehea mai i te haruru papu papamuri. Mā tēnei ka taea e ngā kaitātari te kite i te pakaru o te mata i mua i te putanga mai o te turuturu rahi.

He rite tonu te hiranga o te whakamahana infrared (IR). Mā te mahere i te pikinga wera puta noa i te repe hiri me ngā paipa horoi, ka taea e ngā tohunga hangarau te manatoko mēnā kei te mahi te mahere horoi API. Hei tauira, i roto i te Mahere API 11 (te whakawhiti tukunga ki te hiri), mēnā he ōrite te pāmahana o te raina horoi ki te hau taiao kaua ki te wai tukatuka, tera pea kua purua te kōhao, ka kore e taea te hiri o te rere whakamatao, ā, ka whakaū i te take o te wera nui.

Arotakehia ngā tuhinga tirotiro me te tiaki

He nui te whakawhirinaki o te tika o te tātaritanga ki te horopaki hītori. Me uiui ngā kaihangarau pono i te Pūnaha Whakahaere Tiaki Rorohiko (CMMS) hei arotake i te MTBF me ngā momo rahunga o mua o te rawa motuhake. Mena me hiahia he papuhiri miihini houia ono marama, ā, e whakahua tonu ana ngā pūrongo wawahi i ngā "mowhiti-O kua whakaputahia," ka neke te tātaritanga mai i te take whakatikatika miihini ki te whakatakotoranga rauemi hē (hei tauira, te whakamahi i a Viton i roto i te tono mamaoa pāmahana teitei hei utu mō Kalrez).

He mea nui anō hoki te arotake i ngā raraunga au o te tukanga mai i ngā pūnaha SCADA, DCS rānei i te wā tonu i puta tuatahi ai ngā tohu. He maha ngā wā, ka taea te whai i te pakaru o te hiri ki tētahi raruraru mahi motuhake, pērā i te ngaronga ohorere o te pēhanga momi, te pikinga tere o te pāmahana, te wā rānei i whakahaerehia ai te papu ki te taha o tētahi takirere tukunga kua kati. Mā te tautuhi i ēnei āhuatanga rerekē o te tukanga ka whakaū mēnā i puta te pakaru o te hiri nā tētahi hapa mahi, kaua ki tētahi hapa wāhanga.

Ara Whakatau mō ngā Rōpū Tiaki

Ina whakaūtia ngā tohu whakatūpato, me whakahaere e te kaiārahi tiaki he urupare kua tatauhia. Me whakataurite te tukanga whakatau i te hiahia tonu ki te pupuri i te mahi whakaputa me te mōrearea o te kino nui o ngā taputapu me te kore tutuki i ngā whakaritenga taiao.

Mā te whakatū i tētahi ara whakatau whaimana ka whakarite kia tere te wā, kia haumaru, kia tika hoki te taha ōhanga o ngā wawaotanga. Ka tohutohu tēnei ara i ngā mahi whakaiti tere, ka aromatawai i te taha ōhanga o te whakatikatika me te taha ōhanga o te whakakapinga, ā, ka whakahau i te tātaritanga i muri i te rahunga kia tere ai te whakapai tonu.

Te urupare tuatahi ina puta mai ngā tohu whakatūpato

Ko te urupare tuatahi ki te tohu whakatūpato mō te hiri miihini ko te pupuri me te manatoko. Mēnā ka whiti te turuturu i te paepae o te tangi rerekē, me manatoko tonu ngā kaiwhakahaere kei te kaha te pūnaha horoi hiri, te pūnaha tinei, te pūnaha ārai rānei, ā, kei te tika te takirere. Mā te whakaora i te raina horoi kua āraia o te API Plan 11, te whakaputa rānei i te hau kua mau mai i te rūma hiri, ka taea te whakau i te hiri kua pakaru, ā, ka whakaroa i te pakaru katoa.

I te wā kotahi, me arotake e ngā mahi ngā mōrearea taiao me te haumaru. Mena he matū morearea, he matū mura rānei te wai, ā, he nui ake te turuturu i ngā rohe ture ā-rohe (hei tauira, >500 ppm VOC), he pakari te ara whakatau: me wehe te papu, ā, me whakawhiti ki tētahi wae tūtatari tonu. Mena he pai te wai (hei tauira, te wai whakamatao) ā, he iti noa te turuturu, ka taea e te tīma te whiriwhiri kia whakanuia te auau aroturuki ki ngā wā o ia rā, ki ngā wā whakawhiti rānei, i te wā e whakarite ana i ngā wāhanga whakakapinga.

Āhea te wā hei whakatika, hei whakatika, hei whakakapi rānei i te hiri

Kia mutu te whakamahi i te papu, ka whakatau te tīma tiaki me whakatika, me whakakapi rānei.Ngā hiri mīhini o te kāteretihe tino rerekē. Mena ka toia wawe te hiri—i mua i te hohonu o te haehae o ngā mata, i mua rānei i te wera o ngā wāhanga whakarewa—ka taea te tuku i te hiri ki tētahi whare whaimana hei whakahou. Ko te whakahoutanga he horoi ultrasonic, he whakakapi i ngā mowhiti-O me ngā puna elastomeric, me te whakahoki anō i ngā mata silicon carbide, waro rānei ki te papatahi o te 2-light-band e hiahiatia ana.

Ko te paepae utu-painga paerewa ahumahi e kī ana mēnā he iti iho i te 60% o te utu o tētahi kātere hou te utu hei whakatika i te hiri, ko te whakatika te kōwhiringa ōhanga pai rawa atu. Heoi, mēnā ka warewarehia ngā tohu whakatūpato wawe, ā, ka pāngia te hiri e tētahi āhuatanga maroke kino, ka taea te tohu, te piko rānei o te pūwero whakarewa, te ringaringa kātere rānei. I roto i ēnei āhuatanga, ka tere ake ngā utu whakatika i te paepae 60%, ā, me whakakapi katoa kia pono ai.

Me pēhea te ārai i ngā pakaru hiri anō

Ko te taahiraa whakamutunga o te ara whakatau ko te aukati i te hokinga mai. Mā te whakakapi i tētahi hiri kua rahua me te kore e whakahaere i tētahi Tātaritanga Take Pūtake Rahua (RCFA) ka taea te whakaroa i te mahi a meake nei. Ko ngā taunakitanga ā-tinana kei runga i ngā mata o te hiri kua rahua—pērā i te tirotiro wera, te whakaeke matū, te keri rānei—me ārahi i tētahi whakapainga hangarau.

Mena ka whakaatuhia e te RCFA ko ngā pāmahana teitei te take o te rahunga, me whakapai ake e te tīma te whakaritenga horoi, me te neke pea mai i te Mahere 11 ki te Mahere API 23, e whakamahi ana i te mowhiti papu me te whakawhiti wera hei whakamatao i te wai i roto i te rūma hiri. Mena ko te kakahu whakakoi te take, ko te whakapai ake i te whakarewa mata, te tāuta rānei i te wehewehe awhiowhio (Mahere API 31) hei tango i ngā totoka mai i te wai horoi ka huri tonu i te pihi rahunga, ka huri i ngā raraunga whakatūpato wawe hei pono miihini mo te wā roa.

Ngā Whakaaro Matua

• Aroturukihia te turuturu, te wiri, te pāmahana, te pēhanga, me te kukume hiko ki tētahi paerewa e mōhiotia ana kia kitea ai ngā huringa iti o te hiri i mua i te puta o te pakaru.
• Tirohia tonutia ngā hiri miihini ina huri te turuturu mai i te paku kohu ki te maturuturu, ki te rehu, ki te toenga tioata, ki te putunga wai tukanga rānei e kitea ana.
• Tiakina te pono o te peera mā te whakatika wawe i te turuturu o te hiri, nā te mea ahakoa te iti rawa o te parahanga wai-tukanga i roto i te hinu whakahinuhinu, ka taea tonu te whakaiti i te roa o te peera.
• Manatokohia te tāutanga, te whakarite, te horoi, me te hototahitanga o ngā rauemi ina whakakapia he hiri hei ārai i ngā rahunga anō mai i te pūtake kotahi.
• Whakamahia te hoahoa hiri tika—pēnei i te puna kotahi, te raro elastomer, te kātere, te hiri ā-ringa takirua rānei—i runga i te mahi papu, i ngā āhuatanga wai, i te pēhanga, me te taiao whakahaere.

Ngā Pātai Auau

He aha ngā tohu tōmua o te pakaru o te hiri miihini i roto i te papu?

Ko ngā tohu tōmua noa ko te turuturu e kitea ana, te pikinga o te pāmahana o te rūma hiri, te wiri rerekē, te haruru rerekē, te kore pumau o te pēhanga, te pikinga o te kukume hiko, me te poke o te hinu peera.
