ubuchwepheshe obukhulu | Imboni entsha | Mashi 4, 2025
Ⅰ. Izinselele zendawo yokudlidliza kwemishini yezimayini ohlelweni lwendandatho yokushelela
Izimoto zokumba zisezimweni zokusebenza ezinzima zokudlidliza kwama-frequency amaningi (20-2000Hz), umthelela osheshayo (ukusheshisa okuphezulu ≥15g) kanye nokuhlushwa kothuli >30mg/m³ isikhathi eside 4. Ama-reel endandatho yokushelela yendabuko athambekele ekushintsheni kokumelana kokuthintana (±15%), izinga lokuphutha kwesignali elikhuphukile (>5‰) kanye nezinye izinkinga kule ndawo, okungaholela ezingozini zesikhathi sokungasebenzi kohlelo lokulawula izimoto ezimweni ezimbi kakhulu. Ngokusho kwedatha evela emayini yethusi evulekile ngo-2024, isikhathi sokungasebenzi esingahleliwe esibangelwa ukwehluleka kwendandatho yokushelela singu-38% wesikhathi sokungasebenzi sonke .
Ⅱ. Izixazululo zobuchwepheshe obuyinhloko zokuguqulwa okumelana nokudlidliza
a. Ukuthuthukiswa kwesakhiwo sendandatho yokushelela engathinteki
Yamukela ukwakheka kwe-buffer okunezinga ezintathu:
Isendlalelo sokuxhumana: oxhumana nabo be-beryllium bronze alloy abafakiwe (ubulukhuni be-HV220), abanomklamo we-hyperbolic raceway, ukuguquguquka kwengcindezi yokuxhumana kulawulwa ngaphakathi kwe-±3N
Isendlalelo sokudlulisa: imodyuli yokunciphisa i-disk spring ehlanganisiwe, ingamunca amandla omthelela osheshayo (＞8J), izinga lokudlulisa ukudlidliza lehliswa libe ngu-0.35
Isendlalelo sokufaka: esilungiselelwe ngesisekelo se-polyurethane-steel composite, ukuqinisekiswa kwelabhorethri kunganciphisa i-20Hz vibration amplitude ngo-62%
Umdwebo wokulingisa ukuhlolwa kokushaqeka nokudlidliza
b. Ukulungiswa kohlelo lokuqinisekiswa kwemishini yezimayini i-EMC
Uhlelo lokuguqula lulandela ngokuqinile indinganiso yokuhambisana kagesi kagesi engaqhumi ye-GB/T 3836.4-202X:
Faka isembozo sokuvikela esinezingqimba eziningi (ukusebenza kahle kokuvikela ≥70dB@1GHz)
Lungiselela i-topology yezintambo futhi wehlise i-voltage yokuphazamiseka kwemodi evamile kusuka ku-12V kuya ku-0.8V
Phasa isivivinyo sokungavikeleki kwemisebe engu-10V/m, izinga lephutha le-bit lingu-<0.1‰ (1.2‰ ngaphambi kokuguqulwa)
c. Isixazululo esihlanganisiwe sendandatho yokushelela engangeni manzi futhi engangeni uthuli
Yamukela ubuchwepheshe obuhlanganisiwe bokuvala obunamandla:
Isiciko esiyinhloko: indandatho yesisiciko esijikelezayo se-fluororubber (ukumelana nokushisa -40℃ ~180℃)
Isiciko esiwusizo: isakhiwo sesivikelo somoya se-labyrinth (umehluko wokucindezela komoya ongu-0.05MPa) Sifinyelela ezingeni lokuvikela le-IP68, ukusebenza okuqhubekayo ngaphansi komthelela wokugeleza kwamanzi anothuli (50L/min) isikhathi esingaphezu kwamahora angu-2000 ngaphandle kokuvuza
Isithombe sendandatho yokushelela engangeni manzi futhi engangeni uthuli
III. Idatha yokuqaliswa kwephrojekthi kanye nokuqinisekiswa
Iphrojekthi yokuguqulwa eyenziwe emayini yensimbi ngo-Okthoba 2024 ikhombisa:
Ukubekezelela ukudlidliza: Esivivinyweni sokudlidliza esiqhubekayo samahora angu-8 (imvamisa engu-50Hz, i-amplitude engu-2mm), ukuzinza kokudluliswa kwesignali kukhuphuke ngo-83%
Ukuvikelwa kokushaqeka: Ukulingisa isimo sokuwa kwemoto yemayini (ukuwa kwamahhala kusuka ekuphakameni okungu-1.2m), izinga lobuqotho bezingxenye ezibalulekile lingu-100%
Izindleko zokusebenza nokulungisa: Umjikelezo wokulungisa wendandatho yokushelela welulwa kusukela emahoreni angu-500 kuya emahoreni angu-2000, kanti ukusetshenziswa kwezingxenye zonyaka ezisele kuncishiswe ngo-47%
amapharamitha obuchwepheshe ayinhloko
| Inkomba | Ngaphambi | Ngemva | Ukuthuthukiswa | |
| Ukudluliswa kokudlidliza | 0.78 | 0.35 | 55%↓ | |
| Izinga lephutha lesiginali (‰) | 5.2 | 0.09 | 98%↓ | |
| Izinga lokuvikela | I-IP54 | I-IP68 | Ingangenwa uthuli/ingangenwa manzi | |
| Ukumelana nomthelela (g) | 8 | 15 | 87%↑ | |
Ⅳ. Ukwandiswa kohlelo lokulungisa oluhlakaniphile
Inzwa yokudlidliza yokufaka (isilinganiso sokuhlola esingu-10kHz) ukuqapha isimo sendandatho yokushelela ngesikhathi sangempela
Misa imodeli yokuhlola impilo ukuze ubikezele ngokunembile impilo yesevisi esele (iphutha <8%)
Ukuhlaziywa kwe-spectrum yokuphazamiseka kwe-electromagnetic yamaqoqo emishini angu-20 ngeplatifomu yefu le-EMC
Isiphetho
Lesi sixazululo sakha uhlelo oluphelele lokuvikela ukudlidliza ngokusebenzisa ubuchwepheshe bokumelana nokushayisanaindandatho yokushelelaisakhiwo, ukulungiswa kohlelo lokuqinisekiswa kwemishini yezimayini ye-EMC kanye nokuhlanganiswa kwayoindandatho yokushelela engangeni manzi futhi engangeni uthuliubuchwepheshe. Idatha yangempela yokuhlola ikhombisa ukuthi isikhathi esimaphakathi phakathi kokwehluleka (i-MTBF) kwemishini ngemva kokuguqulwa sikhuphuke kusukela emahoreni angu-1800 saya emahoreni angu-5200, okunikeza isisekelo esihle sokuguqulwa okuhlakaniphile kwezimayini.
