Ngā Whakaaro Matua
- Ka mau te tapahi e ahu mai ana i te taumaha i ngā mea kāore e taea e te tapahi e ahu mai ana i te roa: he rerekē te mātotoru o te matū me te matotoru o te rau, nō reira kāore e maha ngā roa ōrite e whakaputa i te taumaha ōrite.
- Ka honoa e te mīhini tapahi taumaha aunoa a XCJ-A 600 tētahi pūoko taumaha LASCAUX me te mana whakahaere Delta PLC, ka tapahia ki te ātete kua whakaritea e te kaiwhakamahi, ā, ka whakarōpūtia aunoa ia wahi.
- Mā te tapahi i ngā āhua kia iti te taumaha (hei tauira ±0.3 g) ka whakaitihia te nui o ngā para rauemi me te iti o te taumaha o ngā para whakahāngai i te wā kotahi.
- Whakatakotoria ngā wahi whāinga mō ia pokepokea ai (6, 10 rānei) ki te mata pa, ā, ka whāngaihia e te mīhini te tatau tika, ka kore e tatau ā-ringa, ka kore hoki e mahi takirua.
Ko ngā mowhiti-O ngā wāhanga hiri e tino hangaia ana i roto i te umanga rapa, ā, he uira kei roto i ia mowhiti-O kua whakarewaina i tōna rārangi wehenga. Ko te whiriwhiri i te mīhini whakakore i ngā pakaru e pā ana ki te āhua ataahua o te mowhiti-O, tae atu ki tōna mahi hiri, te ōritetanga o ngā āhuatanga, me te utu whakaputa. Ka whakaratohia e tēnei aratohu he anga ine mō te whakataurite i ngā taputapu whakakore i ngā pakaru ki ngā tawhā whakaputa mowhiti-O.
Ngā Whakaritenga Whakakore i te Mowhiti-O: He aha te Mea e Rerekē ai i Ētahi Atu Wāhanga Rapa
He maha ngā wero whakakore i ngā mowhiti-O kāore e kitea i roto i ētahi atu hua rapa. Nā te mea he maha, he rau rānei ngā poka e puta mai ana i te pokepokea mowhiti-O kotahi, ka rere te mura o te raina wehewehe i te diameter o roto me te diameter o waho o ia mowhiti. Ko te tapahi angiangi - ko ngā tapahi mowhiti-O noa mai i te 1.5 mm ki te 8.4 mm iaISO 3601-1— ko te tikanga kei te tata te uira ki te mata hiri mahi. Mā te whakangāwari rawa e tango ai i te rauemi turanga i te hononga uira ka puta he ara turuturu e kore e kitea mā te tirotiro kanohi anake.
Hei tāpiritanga, ka whakarōpūtia ngā mowhiti-O ki raro iASTM D1414mō ngā tikanga whakamātautau paerewa, e tohu ana i ngā tukanga manatoko ā-ahu e kore e taea te whakararu i te wetewete. Mō iaISO 3302-1, ko ngā ātete ā-ahu mō ngā mowhiti-O tino tika kei waenga i te ±0.08 mm mō ngā wāhanga whakawhiti i raro i te 2.5 mm ki te ±0.22 mm mō ngā wāhanga whakawhiti i runga ake i te 10 mm. Me tango te uira i te tikanga whakakore me te kore e whakarerekē i ēnei ā-ahu nui.
Ko tētahi mea kāore i te tino kitea engari he rite tonu te hiranga ko te wāhi o te mura. Ko te rārangi wehenga o ngā pokepokea ai he mowhiti-O kei waenganui o te pokepokea ai, ko te tikanga ka noho tika te mura ki runga i te diameter o te hiri. Ko te whakakorenga e waiho ana he toenga i runga ake i te 0.1 mm i runga i te ID, i te OD rānei, ka puta he hapa hiri e puta ai te turuturu i te pēhanga kua whakatauria. Nā tēnei here āhuahanga ka nui ake te hiranga o te whiriwhiri tikanga whakakorenga mō ngā mowhiti-O i ngā wāhanga rapa āhua koretake ina kore te mura i runga i te mata mahi.
E rima ngā Take Whakatau mō te Kōwhiri i tētahi Mīhini Whakakore Rapa mō ngā Mowhiti-O
Tauwehe 1: Te whānuitanga o te rahi o te mowhiti-O me te wāhanga whakawhiti
Ko ngā āhuatanga ā-tinana o ō mowhiti-O te mea tuatahi e whakatakoto ana i te herenga taputapu. Ka mahi ngā mīhini whakakore pahu miihini i roto i te whānuitanga diameter kua tautuhia. Ko teMīhini whakakore pahu XCJ-G600, me tōna whānui o te pahu 600 mm me te kaha puranga 15 kg, ka tukatukahia ngā mowhiti-O mai i te 3 mm ki te 100 mm te whānui o waho. Ko ngā mowhiti-O iti iho i te 3 mm ka puta noa i ngā pūaha o te pahu, ka noho rānei i roto i ngā tautau, ka whakaiti i te whai huatanga o te tango i ngā pakaru. Ko ngā mowhiti-O neke atu i te 100 mm OD me whakamahi i tētahi pahu nui ake, me ētahi atu whakahaere rānei.
He mea nui anō hoki te whakawhiti i te porowhita. Ko ngā mowhiti-O angiangi me ngā whakawhiti i raro i te 2 mm ka ngawari ake te piko me te pakaru o te mata i te wā e hurihia ana e te mīhini. Mō ēnei, ko te tukatuka cryogenic te whiringa haumaru ake nā te mea he rite te rapa tio ki te rauemi pakari i te wā e pāngia ana e te pāpāho. He ture whai hua e whakamahia ana e mātou i roto i tā mātou wheketere:Ko ngā mowhiti-O me te wāhanga whakawhiti ≥2.5 mm me te OD i waenga i te 8 mm me te 80 mm ngā kaitono tino pai mō te wetewete pahu miihini, ko ngā mowhiti-O ia i waho o tēnei awhe me aromatawai mō te tukatuka cryogenic.
Tauwehe 2: Kōtaha Uira me te Momo Rauemi
Ko te matotoru o te uira te tawhā tino nui o te tukanga. Ka whai hua te whakakorenga ā-ringa ina 0.1, neke atu rānei te ōwehenga matotoru o te uira ki te wāhanga — arā, ka taea te whakakore i te mowhiti-O whakawhiti-wāhanga 3.5 mm me te uira 0.35 mm mā te ā-ringa, engari kāore e taea e te wāhanga-wāhanga 1.8 mm me te uira 0.15 mm. Mō ngā mowhiti-O i hangaia ki ngā taputapu cavitation teitei, ko te uira he 0.1-0.3 mm te nuinga, mā te rauemi e whakatau mēnā he tika te whakakorenga ā-ringa, te whakakorenga cryogenic rānei.
| Rauemi | Tikanga Whakakore i te Kiriata i Manakohia | Tepe Matotoru o te Kikorangi | Take |
|---|---|---|---|
| NBR (Nitrile) | Mīhini (pahu) | ≥0.20 mm | He ātete pai ki te haehae; he ngāwari ngawari |
| EPDM | Mīhini (pahu) | ≥0.20 mm | He rite ki te NBR; he ma te pakaru o te uira |
| HNBR | Mīhini (pahu) | ≥0.15 mm | Ka taea e te kaha teitei ake te tango i te uira angiangi |
| FKM (Viton) | He pai ake te whakamahi i te cryogenic | ≥0.10 mm (kiri) | He uira pakari; he pai rawa ngā hua i te -110°C ki te -130°C |
| VMQ (Hikone) | Me whakahau te mahi cryogenic | ≥0.08 mm (kiri) | He iti te kaha o te haehae; ka haehae te wāhanga e te whakakorenga ā-mīhini |
| FVMQ (Fluorosilicone) | Me whakahau te mahi cryogenic | ≥0.08 mm (kiri) | Ka whakakotahi i te kaha iti o te haehae me ngā hiahia ātete wahie |
Ko te matotoru o te pokepokea ai i inehia i te pūwāhi matotoru rawa o te rārangi wehewehe pokepokea ai. Tērā pea ka rerekē ngā uara tūturu i runga i te hanganga matū me te āhua o te pokepokea ai.
Take 3: Te Rahi Whakaputa me te Rahi o te Puranga
Ka tukatukahia e te XCJ-G600 tētahi puranga mowhiti-O 15 kg i roto i te 20-40 hēkona ia huringa. Mō te taumaha toharite o te mowhiti-O o te 2-10 karamu i runga i te rahi, kei roto i tētahi puranga he 1,500-7,500 mowhiti-O. Mō te 40 hēkona ia puranga me te uta me te tango i te uta, ko te kaha mahi whai hua he tata ki te 60-80 puranga ia nekehanga 8-hāora, 90,000-600,000 mowhiti-O rānei ia nekehanga i runga i te rahi.
Mēnā he nui ake te rahinga o te whakaputanga o ngā mowhiti-O i te 500,000 ia rā, ka tika te whakamahi i tētahi raina cryogenic motuhake mō ngā rahi iti me tētahi raina mīhini mō te awhe matua, engari mō te nuinga o ngā kaihanga rahi-waenga, ka taea e tētahi mīhini pahu mīhini kotahi te whakahaere i te 80-90% o te putea mowhiti-O.Ko te 10-20% e toe ana — ko te nuinga he silicone, he mowhiti-O rānei kei raro iho i te 6 mm te ID — ka taea te tuku ki waho, te whakahaere rānei i runga i tētahi mīhini puranga cryogenic iti.
Take 4: Ngā Whakaritenga Manawanui me te Kounga
E whakarōpūtia ana e te ISO 3302-1 ngā ātete hua rapa kia whā ngā akomanga. Ko te Akomanga A (tika) me ±0.08 mm i ngā wāhanga whakawhiti i raro i te 2.5 mm. Ko te Akomanga B (pai) me ±0.10 mm. Ko te Akomanga C (waenga) me ±0.14 mm. Me āhei te tikanga whakakore i te mura i roto i te awhi ātete me te kore e whakaiti i te wāhanga whakawhiti i raro i te rahinga iti rawa e whakaaetia ana. Mā te whakakore aunoa me te whiriwhiri pāpāho tika ka tutuki tonu ngā ātete Akomanga B me C. Ko te whakakore i te mura cryogenic, me tana tango rauemi whakahaere ake, ka tutuki ngā ātete Akomanga A me B mō ngā mowhiti-O me ngā wāhanga whakawhiti angiangi.Mena kei te hiahiatia ngā āheinga Akomanga A mō ngā wāhanga whakawhiti i raro i te 3 mm i roto i tō whakatakotoranga O-ring, he mea tino taunaki kia whakamahia te wetewete i ngā ārai kiri (cryogenic deflacing).
Take 5: Te Utu Whakahaere Katoa (TCO)
E rua ngā wāhanga utu e kore e arohia whānuitia ana i te wā e whiriwhiria ana te mīhini whakakore i ngā mea: ko te whakamahinga o ngā rauemi me te whakahaere i te hauota wai. Ko te whakakore i ngā mea aunoa ka pau i ngā rauemi hurihuri (ngā pirepire anga kirihou, ngā pirepire anga nati rānei) e hiahia ana kia whakakapia i ia wā. Ko te whakakore i ngā mea cryogenic ka pau i te hauota wai i te 0.5-2.5 kg ia kg o te rapa kua tukatukahia, i runga i te taumaha me te mātotoru o te wāhanga.
| Taonga Utu | Mīhini (XCJ-G600) | Kiriōke (Puranga) |
|---|---|---|
| Te utu hoko mīhini | $8,000-15,000 | $25,000-60,000 |
| Te utu whakahaere mō ia kg o ngā mowhiti-O | $0.08-0.15 (pāpāho + pūngao) | $0.25-0.60 (LN2 + pūngao) |
| Te utu tiaki i ia tau | $500-1,200 | $1,200-3,000 (papu LN2 + takirere) |
| Te wā huringa mō ia puranga | 20-40 hēkona | 3-8 meneti (tae atu ki te wā tio) |
| Wāhi papa e hiahiatia ana | 2.0 mita x 1.5 mita | 3.5 mx 2.5 m (me te tāke LN2) |
| Wā whakahoki utu (noa) | 6-12 marama | 12-24 marama |
Ko ngā utu e ahu mai ana i ngā whakatau tata o te hauwhā tuarua o te tau 2026 mō ngā taputapu e whakahaerehia ana i Haina. Ka rerekē ngā utu LN2 i ia rohe; ka whakaitihia te utu e te tuku papatipu mā te 15-25%.
⚠️ Utu Huna: Te Rerekētanga o te Matotoru o te Matapihi
Mena he koretake te tiaki i tō pokepokea ai, ka rerekē pea te matotoru o te uira mā te 0.3 mm puta noa i ngā kōhao. Mā tēnei rerekētanga ka akiaki koe ki te whiriwhiri i tētahi tikanga tango i ngā mea me ngā tawhā mō te uira matotoru rawa, ka nui rawa pea te tukatuka i ngā mowhiti-O mai i ngā kōhao kikī. Whakangaohia ki te tirotiro pokepokea ai i ia huringa 20,000, ā, kia mau tonu te hohonutanga o te hau ki roto i te 0.05 mm. Mā tēnei mahi kotahi ka whakaitihia ngā whakakorenga tango i ngā mea e whakakorea ana mā te 30-40% i roto i tā mātou wheako whakaputa.
