hangarau auaha | He mea hou te ahumahi | 4 Maehe 2025
Ⅰ. Ngā wero o te taiao wiri o ngā taputapu keri ki te pūnaha mowhiti paheke
Kei roto ngā waka keri i ngā āhuatanga mahi uaua o te wiri auau maha (20-2000Hz), te pānga ohorere (te tere tere ≥15g) me te kukū puehu >30mg/m³ mō te wā roa 4. He ngāwari ngā rīra mowhiti paheke tuku iho ki ngā rerekētanga ātete pa (±15%), te pikinga o te tere hapa tohu (>5‰) me ētahi atu raruraru i roto i tēnei taiao, ka arahi pea ki ngā aituā wā-kore o te pūnaha whakahaere waka i ngā wā tino kino. E ai ki ngā raraunga mai i tētahi maina parahi tuwhera i te tau 2024, ko te wā-kore i whakaritea i puta mai i te pakaru o te mowhiti paheke e 38% o te wā pakaru katoa .
II. Ngā otinga hangarau matua mō te panoni ātete-wiri
a. Whakapai ake i te hanganga mowhiti paheke ātete-pānga
Whakamahia he hoahoa parepare taumata-toru:
Paparanga whakapā: ngā whakapā parahi beryllium kua whakatōkia (pakeke HV220), me te hoahoa ara reihi hyperbolic, ka whakahaerehia te piki me te heke o te pēhanga whakapā i roto i te ±3N
Paparanga tuku: kōwae whakamātao puna kōpae whakauru, ka taea te mimiti i te kaha pānga ohorere (>8J), ka whakaitihia te tere tuku wiri ki te 0.35
Paparanga tāutanga: he mea hanga ki te turanga hiato maitai-polyurethane, ka taea e te manatoko taiwhanga te whakaiti i te kaha wiri 20Hz mā te 62%
Te hoahoa whakatauira whakamātautau ru me te wiri
b. Te whakarerekētanga o te pūnaha tiwhikete EMC mō ngā taputapu keri
E whai pū ana te mahere whakarerekētanga i te paerewa hototahi hiko ātete-pahūtanga GB/T 3836.4-202X:
Tāutahia he taupoki parepare maha-paparanga (te whai huatanga o te parepare ≥70dB@1GHz)
Whakapai ake i te āhua o te waea me te whakaiti i te ngaohiko pokanoa aratau noa mai i te 12V ki te 0.8V
Paahi i te whakamātautau ārai irahiko 10V/m, ko te tere hapa moka he <0.1‰ (1.2‰ i mua i te whakawhiti)
c.Otinga whakauru mowhiti paheke ātete-wai me te ātete-pūehu
Ka whakamahi i te hangarau whakakotahitanga hiri hihiri:
Hiri matua: mowhiti hiri hurihuri rapa fluoro (ātete pāmahana -40℃~180℃)
Hiri āwhina: hanganga ārai arai hau labyrinth (rerekētanga pēhanga hau 0.05MPa) Tae atu ki te taumata tiaki IP68, mahi tonu i raro i te pānga o te rere wai puehu (50L/min) mō te neke atu i te 2000 hāora me te kore turuturu
Pikitia mowhiti paheke ā-wai me te ā-pūngāwerewere
III. Ngā raraunga whakatinanatanga me te manatoko o te kaupapa
Ko te kaupapa whakarerekētanga i whakatinanahia i roto i tētahi maina rino i te Oketopa 2024 e whakaatu ana i:
Ātete wiri: I roto i tētahi whakamātautau wiri tonu e 8-hāora (auau 50Hz, kaha 2mm), i piki ake te pumau o te tuku tohu mā te 83%
Te ārai i te ru: Te whakatauira i te āhua o te hinganga o te motuka maina (te hinganga noa mai i te teitei o te 1.2m), ko te reiti pono o ngā wāhanga matua he 100%
Te utu whakahaere me te tiaki: Kua roa ake te huringa tiaki o te mowhiti paheke mai i te 500 hāora ki te 2000 hāora, ā, kua whakaitihia te whakamahinga o ngā wāhanga tāpui ā-tau mā te 47%
ngā tawhā hangarau matua
| Rārangi | I mua | I muri | Whakapai ake | |
| Te tukunga wiri | 0.78 | 0.35 | 55%↓ | |
| Te tere hapa tohu (‰) | 5.2 | 0.09 | 98%↓ | |
| Taumata tiaki | IP54 | IP68 | Ātete puehu/ātete wai | |
| Ātete pānga (g) | 8 | 15 | 87%↑ | |
Ⅳ. Te whakawhānui ake i te pūnaha tiaki atamai
Pūoko wiri whakatō (tere tauira 10kHz) hei aroturuki i te āhua o te mowhiti paheke i te wā tūturu
Whakatūria he tauira aromatawai hauora hei matapae tika i te roanga o te ora ratonga (hapa <8%)
Te tātari i te whānuitanga o te pokanoa hikohiko o ngā tautau taputapu e 20 mā te tūāpapa kapua EMC
Whakamutunga
Ka hangaia e tēnei otinga he pūnaha tiaki wiri katoa mā te auahatanga o te ātete-pāngamowhiti pahekehanganga, urutaunga o ngā taputapu maina, pūnaha tiwhikete EMC me te whakaurunga omowhiti paheke ātete-wai, ātete-pūngāwerewerehangarau. E whakaatu ana ngā raraunga whakamātautau tuturu kua piki ake te wā toharite i waenga i ngā rahunga (MTBF) o ngā taputapu i muri i te whakawhiti mai i te 1800 hāora ki te 5200 hāora, he tūāpapa pai tēnei mō te whakawhiti atamai o ngā maina.
