Ina tohua e te tari kounga he pereti mata karāhe, ko te rārangi kotahi tino nui o te tuhi ko temāka. Mā te tohu e whakatau te ātete papatahi me whakamana e te kaihanga, ā, māna e whakatau tika mēnā he pai te pereti mō te mahi whakatikatika, te tirotiro hou, te tahora whānui rānei o te papa toa. Ko te wero ko te noho tahi o ngā paerewa matua e whā i roto i te hokohoko ā-ao: TiamanaDIN 876, AmerikaASME B89.3.7, HainamanaGB/T 20428, me te USWhakatakotoranga ā-Motu GGG-P-463cE whakamārama ana tēnei aratohu i te tikanga o ia māka, me pēhea te pānui i ngā ātete papatahi, me pēhea hoki te whiriwhiri i te māka tino whai hua mō tō tono.
He aha te Whakamārama Tuturu o te "Māka"?
He papatahi te kōeke, ehara i te whakaahuatanga o te kōhatu tonu. Mō ia kōeke, ka tautuhia e te paerewa te rerekētanga mōrahi o te mata mahi mai i te papa tūturu, e inehia ana puta noa i te whakarara o te pereti, ā, e whakaaturia ana i roto i ngā maikiromita (inihi rānei). E rua ngā ture e pā ana ki ngā paerewa katoa:
- Ka tauinehia te manawanui e te rahi.E rua pea te nui o te manawanui o tētahi pereti 2000 × 1000 mm o te momo kotahi, ā, he rite tonu te rahi o te manawanui ki tētahi pereti 1000 × 630 mm. Me whakataurite tonu ngā manawanui i te roa whakarara kotahi.
- Ko te taumata o ia māka he tata ki te haurua o te manawanui o tetahi atu.Mā te piki ake i te kotahi tohu (hei tauira, 0 → 00) ka haurua te rerekētanga e whakaaetia ana; mā te heke iho i te kotahi tohu ka rua. Koia te take he nui te pānga o te whiriwhiri i te tohu tika ki te utu.
Ka manatokohia e ngā kaiwhakarato whai mana ia pereti ki te paerewa e tika ana i roto i te taiao e whakahaerehia ana te pāmahana (20 °C te pai) ā, ka tukuna he tiwhikete whakatikatika, he tiwhikete tirotiro rānei me ngā uara ine. Mena kāore i roto i te whakatau tata te whakarārangi i te paerewa, te tohu me te tau papatahi kua whakamanahia, whakaarohia he kore oti - tirohia ā mātou tuhipoka mōte ine me te tirotiro i te karāhe.
Koeke DIN 876 (000 / 00 / 0 / 1 / 2)
Ko te DIN 876-1 te paerewa e tino whakamahia whānuitia ana i Ūropi me Āhia. E rima ngā taumata e tautuhia ana, mai i te Tohu 000 tino tika ki raro ki te Tohu 2 o te awheawhe. Ko ngā ātete papatahi noa mō te pereti me te1000 mm te whakararatata ki:
| DIN 876 Tau | Papatahi Noa (1000 mm te whakarara) | Te Whakamahinga Noa |
|---|---|---|
| 000 | ≈ 2.5 µm | Ngā paerewa tohutoro, ngā taiwhanga whakatikatika |
| 00 | ≈ 5 µm | Te ine tika, te whakatikatika ine, te tohutoro CMM |
| 0 | ≈ 10 µm | Ngā rūma tirotiro paerewa, ngā tari kounga |
| 1 | ≈ 20 µm | Te mahi i te rūma taputapu, te jig me te taputapu |
| 2 | ≈ 40 µm | Te tahora whānui o te awheawhe me te tohu |
Papatahi DIN 876 māka 00koinei te paearu e tonoa ana e te nuinga o ngā kamupene tirotiro ina tautoko te pereti i ngā taputapu ine, ina mahi rānei hei tohutoro mahi mō te whakatikatika. Mō te whakatairite tika, me tono tonu ki ngā kaiwhakarato kia whakahuatia te uara kua whakamanahia i te hauroki tuturu o te pereti e hokona ana e koe, me te whakaū i tete tika o te pereti mata karāhee tautokona ana e tētahi tiwhikete kua tuhia.
Ngā Tohu ASME B89.3.7 (AA / A / B)
E toru ngā tohu reta e whakamahia ana e te paerewa Amerikana ASME B89.3.7, i tatauhia mai i ngā tātai i runga i te whakarara pereti kaua i te ripanga pumau:
- Taumata AA (Taumata Taiwhanga)— te manawanui tino pūmau, i hangaia mō ngā taiwhanga ine me ngā pereti tohutoro matua.
- Taumata A (Taumata Tirotiro)— tata ki te rua te nui o te manawanui AA; te whiringa paerewa mō ngā tari whakahaere kounga.
- Taumata B (Taumata Rūma Utauta)— tata ki te rua te ātete A; he pai mō te tahora, te hanga taputapu me te mahi miihini whānui.
Hei tohutoro whakawhiti whānui, he rite tonu te kaha o te ASME Grade AA ki te DIN 876 Grade 00, ā, e tata ana te Grade A ki te DIN Grade 0. He mea nui ngā tātai ina whakatauritehia ngā whakahua: e rua ngā kaiwhakarato e whakahua ana i ngā pereti "Grade A" o ngā rahi rerekē kāore e tuku ana i te manawanui ōrite mēnā kāore te hauroki i te ōrite.
GB/T 20428 me te Federal Spec GGG-P-463c
Te paerewa ā-motu o HainaGB/T 20428Mō ngā pereti mata karāhe, e whai ana rātou i te hanganga akomanga 000/00/0/1/2 me te rapunga whakaaro manawanui rite tonu ki te DIN 876, nō reira ka taea te aromatawai i ngā pereti i hangaia i Haina kua whai tiwhikete GB 00 ki ngā tumanakohanga DIN 00 — mena ka tirotirohia e te kaihanga i raro i te pāmahana whakahaeretia, ā, ka tuhia hoki ngā hua.
Te USWhakatakotoranga ā-Motu GGG-P-463cKo te tuhinga tawhito a te kāwanatanga e whakamahi ana hoki i ngā māka AA / A / B. He maha ngā tono a te kāwanatanga o Amerika me ngā tuhi tawhito e whakahua tonu ana i tēnei. Kua whakakapia i roto i ngā mahi arumoni e te ASME B89.3.7, engari kei te mau tonu ngā ingoa māka i ngā tuhi, nō reira me whakaū ngā tīma hoko ko tēhea tuhinga e pā ana te manawanui ina kīia ana ko "Māka A" anake i roto i te tuhi.
Whakatauritenga Paerewa Whakawhiti (Tohu)
| Kaupapa | DIN 876 / GB/T 20428 | ASME B89.3.7 / Federal GGG-P-463c |
|---|---|---|
| Taiwhanga Whakataurite, tohutoro matua | 000 – 00 | AA |
| Rūma tirotiro QC, pereti e karapoti ana i te CMM | 00 – 0 | AA – A |
| Rūma taputapu, tirotiro ine | 0 – 1 | A |
| Te tahora o te awheawhe, te tohu | 1 – 2 | B |
Kia mōhio: he tauira tohu ngā ripanga i runga ake nei mō te whakarara ~1000 mm. Me manatoko tonu i ngā uara manawanui tika ki te putanga o nāianei o te paerewa e tika ana, ā, me tono hoki mō ngā raraunga ine a te kaihanga.
Me pēhea te Pānui me te Manatoko i tētahi Whakatakotoranga Papatahi
- Tirohia te paerewa me te putanga tohutoro— He koretake te kupu "Reanga 00" kāore he tohu paerewa (DIN 876, GB/T 20428, me ētahi atu).
- Whakaūtia te rahi whakarara i whakamahia mō te manawanui— ka tautuhia te manawanui ki runga i te whakarara, ehara i te whānui.
- Pātai atu mō te papatahi o te rohe me te tika o te pānui anō— ka taea e te pereti te whakatutuki i te papatahi whānui engari he pōkaikaha ā-rohe e pā ana ki te ine i te wāhanga iti.
- Me whai tiwhikete me ngā uara ine me te āheinga ki te whai— ko te ine tika, ka taea te whai i raro i ngā āhuatanga 20 °C te mea e huri ai te kereme manawanui hei taunakitanga. He wāhanga matua tēnei o tā mātoute tukanga whakatikatika me te tirotiro.
- Tauwhāitihia te tūnga me te pūnaha tautoko— kāore e mau te āhuahanga whaimana o tētahi pereti Karaehe 00 i runga i tētahi tūnga kāore i te rawaka. Ko ngā tautoko ira-toru, i ngā tautoko whakamātao rānei, he wāhanga o te kete tika.
Me pēhea te whiriwhiri i te karaehe tika me te kore e nui rawa te utu
Ko te hoko i ngā mea e tika ana te mea tino maumau; ko te hoko i ngā mea e kore e tika ana te mea nui ake te utu. He aratohu whai hua mai i ngā rau o ngā kaupapa e whakahaerehia ana eTe tukanga hanga a ZHHIMG®:
- Tauritehia te māka ki te taputapu, kaua ki te pukapuka iti.Me whai mata tohutoro pumau te CMM (taumata 00/A noa), engari kāore he painga o te tēpu tohu i roto i te toa hanga i te Taumata 000.
- Hokona te rahi kotahi, ka rua ngā māka.He iti ake te utu ki te hoko i te rahi tika me te taumata tika inaianei i te whakahoki anō, i te whakakapi rānei i tētahi pereti i tohua he iti rawa te taumata mō ngā taputapu a meake nei.
- Whakaarohia ngā papa, ngā whakaurunga me ngā pou miro i te wā whakarite.Mā te tāpiri i ēnei i muri mai ka kore te papatahi e pā, ā, ka kore hoki e whai mana te tiwhikete.
- Whakamaherehia ngā wā whakatikatika anō.Ahakoa he pereti kerēme pumau, me manatoko anō i ia wā; ka āta haere te nekehanga o te manawanui, ā, ka kore e kitea.
Mō ngā kaupapa e whakauruhia ana te pereti ki roto i tētahi mīhini, i tētahi pūnaha ine rānei, kaua ki te whakamahi takitahi, ko ngā whakaritenga āhuahanga ka tuhia mō ia wāhanga ki runga i te tuhi — ka taea e tā mātou tīma te arotake i ngā manawanui me te tautoko i te whakatakotoranga katoa, mai i te kōwhiringa rauemi ki te tuku kua whakamanahia, e ai ki te whakaahuatanga i roto i tā mātou tuhinga.ngā āheinga o te karāhe tino tika.
Whakamutunga
He reo whakawhitiwhiti ngā tohu pereti mata karāhe i waenganui i tō tari kounga me te kaihanga — engari mēnā ka whakahuatia e te katoa te paerewa, te rahi me ngā uara kua whakamanahia. Ahakoa kei roto i tō tuhi te DIN 876 Grade 00, ASME Grade AA, GB/T 20428 Grade 0 rānei, ka hangaia, ka whakamanahia hoki e ZHHIMG® ngā anga e whā, me te ine ka taea te whai i roto i ngā āhuatanga e whakahaeretia ana te pāmahana.
Kua rite koe ki te tohu i tō pereti? Tukuna mai te rahi, te tohu, te paerewa rānei e hiahiatia ana, me tō tono — ka whakaū ā mātou kaihangarau i te ātete papatahi, ka tūtohu i te pūnaha tautoko, ka whakahua i tētahi pūrongo tirotiro whaimana.
