Ngā Utauta Keri Aronga Tikanga

E toru ngā take hei aro atu ki te whakahaere i te ara o te poka wai:

① Hoahoa tika te huihuinga poka o raro (BHA) kia taea ai te whakahaere i te tere o te huringa o te koki peka o te poka.

② Hoahoahia, tīpakohia rānei ngā taputapu keri poka me ngā hanganga motuhake hei whakahaere i te tere o te huringa o te koki azimuth o te poka.

③ Kōwhiria me te whakahaere i te taumaha i runga i te mata (WOB) kia tika ai te whakahaere i te tere o te urunga poutū o te mata me te nui o ngā kaha hanganga, kia taea ai te whakahaere i te piko o te poka.

Ko ngā taputapu keri ahunga tuku iho ko ngā raro ahunga, ngā kara keri kore-aukume (NMDC), ngā paipa keri taumaha (HWDP), ngā whakau, ngā horoi nohoanga kī, me ētahi atu.

I. Te Ahunga Iti

1. Ngā momo

Pūwero anga-tika: Whakamahia mō te keri anga-tika me ngā wiri poka whakarunga whare-piko (PCD).

Piko piko ahunga: Whakamahia mō te keri ahunga me ngā keri poka ahu whakamua (PCD).

2. Hanganga Taketake

1) Te Ara Tūturu o te Iti

Ngā Wāhanga: Whare 4, ringaringa pokapū 1, kī ahunga 3, tīwiri whakatakoto 2

2) Te Piko Aronga-ā-Toi

Ngā Wāhanga: Whare 4, ringaringa pokapū 1, kī ahunga 3, tīwiri whakatakoto 2. Ki te whakatauritea ki te raro tika ahunga, he koki piko hanganga λ tōna, ā, ko te tātai tatau ko:λ = 57.3 × (a – b) / d

II. Kara Wiri Kore-Aukume (NMDC)

1. Mahi

Āraia ngā taputapu ine aukume hei karo i ngā hapa ine.

Whakahaerehia ngā mahi a ngā kara wiri noa.

2. Ngā Rauemi o ngā Kara Wiri Kore-Aukume

Ko te nuinga o ngā mea ko te koranu Monel (kei roto ko te parahi, te nikara, te chromium, me ētahi atu), te koranu chromium-nickel, te koranu austenitic i runga i te chromium-manganese, te koranu beryllium-parahi, te maitai kore-aukume SMFI, me te maitai manganese-chromium-nickel ā-whare.

3. Kōwhiringa o te Roa o te Kara Wiri Kore-Aukume

Tirohia te "Mahere o te Kaha o te Papa Aukume o te Whenua Whakapae". Mā te whiriwhiri tika i te roa o te kara keri kore-aukume ka taea te ine tika i te azimuth aukume i te wāhanga poka tuwhera. Ko te teitei ake o te kaha aukume o te rohe, ko te roa ake o te kara keri kore-aukume e hiahiatia ana.

4. Te Tirotiro me te Whakamahinga o ngā Kara Wiri Kore-Aukume

1) Ko te tika o te mata porotaka o waho o te kara wiri kore-aukume me ≤ 2mm/m, ā, ko te tika o te roa katoa me ≤ 5mm/m.

2)Kaua ngā karawarawa i te mata o te tinana paipa o te kara wiri kore-aukume e neke ake i te rohe karawarawa kua whakaaetia.

3)Me maeneene te mata o te miro, kaua he tohu koretake, he ngatata, he pakaru, he kino rānei e whakaaetia.

4）Me ≥ te taipana hanga ake o ngā miro kara wiri kore-aukume i te taipana hurihuri iti rawa kua tohua.

5)Me tirotirohia te urunga aukume me te ōritetanga aukume o te kara wiri kore-aukume kotahi i te tau, ā, me tutuki ngā hua tirotiro i ngā whakaritenga o te Paerewa Kara Wiri Kore-Aukume (SY5145-86).

III. Paipa Wiri Taumaha (HWDP)

Ka whakamahia ki raro i te BHA hei whakakapi i ngā kara wiri hei pēhi. I roto i ngā mahi ahunga me ngā taputapu urungi, ka whakaitihia te wāhi pa ki te pakitara poka, ka whakaitihia te ātete ki te waku, ka whakahaere i ngā mahi reti, ka whakarei ake i te haumaru ki raro i te poka, ā, he pai hoki mō te whakahaere i ngā tawhā ahunga o te poka. Ka mahi anō hoki hei wāhanga whakawhiti i waenga i ngā kara wiri me ngā paipa wiri hei whakaiti i ngā huringa pakari.

IV. Kaiwhakaū

1.Ngā Whakamahinga o ngā Whakapūmau i roto i te Keri Aronga

I roto i ngā BHA hanga-ake me ngā BHA taka-iho, ka mahi ngā mea whakau hei pou tautoko. Mā te whakarerekē i te tūranga o ngā mea whakau i te BHA o raro, ka taea te whakarerekē i te āhua taumahatanga o te BHA o raro kia eke ki te whakahaere i te ara o te poka wai.

2.Whakanuia te pakari o te BHA o raro hei whakau i te pekapeka me te azimuth o te kōhao. I roto i ngā BHA koki-pupuri, ka whakanuia te pakari o te BHA o raro mā te whakaiti i te tawhiti i waenga i te moka me te whakau, me waenga i ngā whakau, kia whakawhāitihia ai te whakarerekētanga pēhanga o te BHA o raro, kia tutuki ai te pānga o te pupuri i te pekapeka.

3.Whakakākahuria te poka wai kia māeneene, kia ngawari hoki te whakarerekētanga o te piko o te poka wai, hei āwhina i te whakaiti i ngā raruraru o raro i te poka.

Kia mōhio! I te wā e whakahaerehia ana te whakapūmau ki roto i te puna, ā, e tangohia ana i waho i te puna, me ata ine te diameter o waho o te whakapūmau, tirohia tōna āhua pakaru me te tūranga tāutanga i roto i te BHA. Kaua te diameter o waho o te whakapūmau e neke ake i te 2mm.

Ngā momo whakaū:

Whakapūmau ōrite rara-tika Whakapūmau porowhita-rima-rōpū (rōpū-toru)

Whakapūmau porowhita rima-rōpū (toru-rōpū)R Pūmau whakaū whakakapinga

Whakapūmau rerekē e toru-rōpūWhakapūmau whakakapinga

V. Kaiwhakawātea Nohoanga Kī

He rite te āhua ā-ira o te horoi nohoanga-kī ki te āhua o te whakapūmau porowhita. He iti ake tōna rahinga whānui i te whakapūmau engari he nui ake i te kara wiri. He rerekē i te whakapūmau porowhita, ko ngā pakihiwi whakarara o runga me raro o te horoi nohoanga-kī he mea whakarewa ki ngā irahiko koranu mārō kia hanga he āhua kōniko, ā, he mahi tapahi, he whakatārewa, he horoi nohoanga kī.

Ko te tūranga o te horoi nohoanga kī i roto i te aho wiri penei:

1. BHA Motuhake mō te Horoi i ngā Nohoanga Kī

Whirihoranga BHA mō te muru i ngā nohoanga kī whānui: Mīti + kara wiri iti (50~60m) + horoi nohoanga-kī + ipu keri + paipa keri taumaha (HWDP).

Mō te muru i ngā nohoanga kī roa ake, ka taea te whakamahi i te BHA e whai ake nei: Mata + 1 tūnga kara wiri iti + horoi nohoanga kī + 1 tūnga kara wiri iti + hononga ngāwari + ipu wiri + paipa wiri taumaha (HWDP).

Me rite te whānui o waho o te kara wiri iti i roto i te aho wiri ki te whānui o waho o te hononga paipa wiri e whakamahia ana i te wā keri. Ina whakahaerehia te aho wiri ki te 100m i runga ake i te nohoanga matua, whakahaerehia te tere oma; ina tūtaki koe ki te ātete, tīmata te huri me te whakahaere tika i te WOB (ko te tikanga he iti iho i te 49kN).

2. Te Horoi i te Nohoanga Kī i te Wā e Keri Ana

I roto i te keri ahunga, mai i te wāhanga hanga-ake, ka whakamahia pinepinetia ngā horoi nohoanga-kī i roto i te BHA o raro. E ai ki te piko o te poka keri me te hanganga o te hanganga, ka whakamahia te horoi nohoanga-kī mō te whakakī anō i ngā wāhanga "waewae-kuri" kei reira pea ngā nohoanga-kī e hangaia ai, kia kore ai e hangaia te nohoanga-kī.

VI. Takirere Whakarewa

Ko āna mahi matua he ārai i te rere whakamuri o te wai keri (ka kino pea ngā taputapu ine o raro i te poka) me te ārai i te aukati i ngā pūwero moka.

VII. Iri Iti

Kei roto i te taputapu Ine i te Wā e Keri Ana (MWD), e whakarato ana i te taiao ine haumaru, pumau hoki mō te MWD.

He rārangi tauine taha-teitei kei te pakitara o waho o te iri raro, e whakamahia ana hei whakatikatika i te taha teitei o te keri poka whakamua (PCD) me te ine i te uara taupatupatu i waenga i te MWD me te PCD. Kei te pakitara o roto o te iri raro he kī e puta mai ana, e whakamahia ana ina whakatakotoria te MWD. ​​Ina kore te MWD e whakamahia ana, me aro ki te tango i te iri raro i te tuatahi kia kore ai te kī e horoia atu i te nui o te rere (tērā pea ka puta he aituā ki raro i te poka).

VIII. Ipu

Ko tāna mahi matua he pupuri i te taurite o te aho mata me te aho wiri, me te āwhina ki te wetewete i te paipa e piri ana ina piri te paipa.

IX. Hononga Ngāwari

Ko tāna mahi matua he tiaki i te ipu, me te whakanui ake i te ngāwari o te aho wiri i te wā e wiri ana.
