Tukanga Hanga Takirere Pūrerehua Hiri-Ngāwari - Aratohu Katoa

Ngā takirere pūrerehua hiri-ngāwarie whakamahia whānuitia ana i roto i te tuku wai me te rerenga wai, te HVAC, te maimoatanga wai, te tiaki ahi, me ngā pūnaha paipa ahumahi nā te mea he pai te mahi hiri, he ngāwari ki te whakahaere, me te utu iti. Hei whakarite i te mahi hiri pono me te roa o te ora ratonga mō ia takirere, ko te tukanga whakaputa he tikanga hanga me te tirotiro pakari.

Hipanga 1: Te Hoko me te Whakarite Rauemi Mata

Ko ngā rauemi mata e hiahiatia ana mō te hanga i ngā takirere pūrerehua hiri-ngohengohe, ka riro mai i runga anō i ngā ota a te kiritaki, ngā tuhi hoahoa, me ngā paerewa hangarau.

Ko ngā rauemi matua ko:

* Ngā rauemi o te tinana takirere: Rino ngāwari (GGG40, GGG50), WCB/LCB/LCC, maitai kore waikura, me ētahi atu;
* Ngā rauemi kōpae takirere: rino mātotoru, CF8, CF8M, 2205 maitai kore waikura takirua, me ētahi atu;
* Ngā rauemi o te kakau takirere: SS410, SS420, SS431, 17-4PH kowiri tira, me ētahi atu;
* Ngā rauemi nohoanga takirere: Ngā rauemi rapa, ngā rauemi polymer rānei pērā i te EPDM, NBR, PTFE, FKM, me ētahi atu;
* Ngā wāhanga āwhina: Ngā whakapiri, ngā pine, ngā pūwero, me ētahi atu.

Me tutuki ngā rauemi katoa i ngā paerewa o te ao me ngā whakaritenga a te kiritaki.

Hipanga 2: Tirotiro Rauemi Mata

I te taenga atu ki te wheketere, ka tirotirohia whānuitia ngā rauemi mata e te tari whakahaere kounga kia mōhio ai kei te tutuki i a rātou ngā whakaritenga whakaputa. Ko ngā mea matua e pā ana ki te tirotiro ko:

2.1 Te tātaritanga hanganga matū;

* Tātaritanga karuārai whakarewa mō te pūngāwerewere i roto i te rino ngāwari:
Taumata | Pūngāwerewere
Tau 1 | ≥90%
Tau 2 | 80–90%
Tau 3 | 70–80%
Tau 4 | 60–70%
Tau 5 | <60%

* Tātaritanga ine-ā-ira:
Te ihirangi waro
Te ihirangi o te chromium
Te nui o te nikara
Te ihirangi o te molibdenum
Te nui o te whanariki me te phosphorus
Me whakarite kia ōrite te taumata o te rauemi ki te tiwhikete rauemi i whakaratohia e te kaiwhakarato.

2.2 Tirotiro i ngā āhuatanga;

Kāore e hiahiatia he tino tika mō ngā inenga whakarewa/whakairo, nā te mea ko te tukatuka raina huihuinga i muri mai ka uru atu ki ngā tirotiro pakari, maha-wāhanga. Me whakataurite ngā inenga ki ngā tuhi me ngā tahua e puritia ana (arā, kaua ngā inenga e heke iho i te tahua miihini iti rawa).
* Tinana takirere:
Te whānui o waho o te flange/te matotoru o te pakitara
Ahu kanohi-ki-kanohi (roa hanganga)
Teitei o te tinana takirere
Te matotoru o te flange o runga
Te whānui o roto o te rerenga rere
* Kōpae takirere:
Te whānui o waho
Te matotoru o te pokapū/te matotoru o te taha
* Kakau takirere:
Diameter
Roa
* Nohoanga takirere:
Te whānui o waho
Diameter o roto

2.3 Tirotiro ā-kanohi;

Ngā tirotiro matua: Tirohia te tinana o te takirere me te kōpae mō ngā kapiti, te pūngao, ngā whakaurunga paru, me ētahi atu; tirohia te nohoanga mō ngā kōhao, ngā hapa rauemi rānei (ngā rauemi ngaro).

2.4 Arotake i ngā tuhinga whakamana rauemi.

I te nuinga o te wā ka haere tahi mai ngā tiwhikete rauemi me te uta, e whakaatu ana i ngā āhuatanga matū, ngā āhuatanga ā-tinana, me ngā tau aroturuki pēnei i ngā tau wera.

Hipanga 3: Te miihini me te hanga waahanga

Ko ngā rauemi mata kua paahitia te tirotiro ka tukuna ki te awheawhe miihini CNC.

3.1 Te miihini tinana takirere

Tetinana takireree hiahiatia ana ngā tukanga e whai ake nei:

* Te miihini mata flange;
* Te miihini mata hiri;
* Te miihini i te pū o te toki;
* Te miihini o te flange o runga;
* Te keri, te tā, me ētahi atu

Ngā tawhā whakahaere matua:
Te honohono
Papatahi
Te tika o te tūnga o te kōhao

Me whakarite kia tutuki ngā inenga tāutanga ki ngā paerewa pēnei i te ISO 5211, EN 593, me te API 609.

3.2 Te mīhini kōpae takirere

* Te miihini i te taha hiri (te porowhita o waho);
* Te miihini i te poka hononga kakau.

Kia tino whai hua te hononga hiri i waenganui i te kōpae takirere me te nohoanga takirere. 3.3 Te Mīhini i te Kakau Takirere

* Te miihini i ngā ara kī;
* Te miihini mutunga;
* Te whakakanapa.

Ka mahia ēnei mahi hei whakapakari i te ātete ki te kakahu me te tika o te huihuinga.

3.4 Te Hanganga Nohoanga Takirere

Koinei te wāhanga tino nui o te takirere pūrerehua ngohengohe-nohoanga. Ahakoa he nohoanga ngohengohe ka taea te whakakapi, he nohoanga tuara mārō, he nohoanga whakapūkara rānei,
Ko te mahi tuatahi ko te whakaranu i te rapa kia rite ki tētahi tauira motuhake hei hanga i te matū rapa turanga.
I te nuinga o te wā, ka tāpirihia ngā rauemi matua pēnei i te rapa maori me te pango waro ki ngā ōwehenga motuhake, me ngā momo tāpiringa rerekē.

Ka whakatauhia e ngā tātai rerekē:

Ātete pāmahana
Ātete ki te waikura
Huinga kōpeketanga
Ko te taahiraa tuarua ko te pēhi mīhini i te matū ki roto i ngā rau rapa me te whakamātautau i ngā āhuatanga o te rauemi, me te whakatau i te pāmahana me te wā whakahāngai tino pai.
I te taahiraa whakamutunga, whai muri i te totoro ā-mīhini, ka pāngia te rauemi e:
* Hanganga kōpeketanga—mō ngā nohoanga ngohengohe ka taea te whakakapi;
* Te whakapūkara—mō ngā nohoanga whakapūkara;
* Te hononga rapa-ki-te-whakarewa—mō ngā nohoanga tuara mārō;

Mā tēnei ka tika ngā ine o te nohoanga, ka ōrite te ngāwari, ā, ka pumau hoki te mahi hiri.

Hipanga 4: Te Ine i te Ahu Tika

I muri i te whakahaere i ngā mahi miihini i ia wā, i ia wā,ngā inenga tikao te wāhanga me ine i konei.

* Tinana Takirere:
Te whānui o waho o te flange/te matotoru o te pakitara
Te whānui o te kōhao flange, PCD
Ahu kanohi-ki-kanohi (roa hanganga)

Hipanga 5: Te Maimoatanga Mata me te Paninga Ārai-Waikura

I muri i te miihini, ka tukatukahia te mata o ngā wāhanga whakarewa.

Ko ngā tukanga noa ko:

* Te pupuhi onepu: Te whakamahi i te kirikiri maitai tere-rahi hei tango i te unahi, te waikura, te hinu, me ngā poke;
* Te whakapūkara me te whakakorekore (ngā wāhanga kowiri tira anake);
* Te whakakanapa hiko (ngā wāhanga kowiri tira anake).

Ko ngā mata o te tinana takirere ka pania ki te paura kapia epoxy.

Ko te matotoru o te paninga i te nuinga o te wā neke atu i te 250 μm, e whakarei ake ana i te ātete ki te waikura, te roa o te mahi, me te ātaahua o te hua.

Ka taea te pani i ngā paninga ārai-waikura motuhake mō te wai moana, te tukatuka matū, ngā taiao tino waikura rānei. Hipanga 6: Te Huihuinga o te Takirere Pūrerehua

I muri i te miihini me te tirotiro, ka whakawhitia ngā wāhanga katoa ki te awheawhe huihuinga whakamutunga.

Hipanga 6: Te Huihuinga o te Pūrerehua

Tetukanga huihuingakei roto i te nuinga:
