Layer na watsawa: tsarin damping na faifan diski mai haɗawa, yana iya shan kuzarin tasiri nan take (＞8J), ƙimar watsa girgiza an rage zuwa 0.35
Tsarin shigarwa: an saita shi da tushen haɗin polyurethane-steel, tabbatar da dakin gwaje-gwaje na iya rage girman girgizar 20Hz da kashi 62%
Zane-zanen kwaikwayon gwajin girgiza da girgiza
b. Daidaita tsarin takardar shaidar EMC na kayan haƙar ma'adinai
Tsarin canji ya bi ƙa'idar da ta dace da ƙarfin lantarki na lantarki mai hana fashewa ta GB/T 3836.4-202X:
Shigar da murfin kariya mai matakai da yawa (tasirin kariya ≥70dB@1GHz)
Inganta yanayin wayoyi kuma rage ƙarfin tsangwama na yanayin gama gari daga 12V zuwa 0.8V
Cika gwajin rigakafi na radiation na 10V/m, ƙimar kuskuren bit ɗin shine <0.1‰ (1.2‰ kafin canjin)
c. Maganin zamewa mai hana ruwa da ƙura wanda aka haɗa
Yana ɗaukar fasahar haɗa hatimi mai ƙarfi:
Babban hatimi: zoben hatimi mai juyawa na fluororubber (juriyar zafin jiki -40℃~180℃)
Hatimin taimako: tsarin shingen labulen iska mai labyrinth (bambancin matsin lamba na iska 0.05MPa) Isa matakin kariya na IP68, aiki mai ci gaba a ƙarƙashin tasirin kwararar ruwa mai ƙura (50L/min) na tsawon awanni sama da 2000 ba tare da zubar ruwa ba
Hoton zoben zamewa mai hana ruwa da ƙura
III. Bayanan aiwatar da aikin da tabbatarwa
Aikin sauyi da aka aiwatar a ma'adinan ƙarfe a watan Oktoba na 2024 ya nuna:
Juriyar girgiza: A cikin gwajin girgiza mai ci gaba na awanni 8 (mita 50Hz, girman 2mm), daidaiton watsa siginar ya ƙaru da kashi 83%
Kariyar girgiza: Yin kwaikwayon yanayin faɗuwar motar haƙar ma'adinai (faɗuwa kyauta daga tsayin mita 1.2), ƙimar daidaiton mahimman abubuwan haɗin shine 100%
Kudin aiki da kulawa: Zagayen gyaran zoben zamewa yana ƙaruwa daga awanni 500 zuwa awanni 2000, kuma yawan amfani da kayan gyara na shekara-shekara yana raguwa da kashi 47%

Ⅳ. Fadada tsarin kulawa mai wayo
Na'urar firikwensin girgiza da aka dasa (ƙimar samfurin 10kHz) don sa ido kan yanayin zoben zamewa a ainihin lokaci
Kafa tsarin kimanta lafiya don yin hasashen daidai tsawon lokacin da zai rage aiki (kuskure <8%)
Binciken bakan tsangwama na lantarki na tarin kayan aiki 20 ta hanyar dandamalin girgije na EMC
Kammalawa
Wannan mafita tana gina cikakken tsarin kariyar girgiza ta hanyar kirkire-kirkire na juriya ga tasiri.zoben zamewatsarin, daidaitawa da tsarin takardar shaidar EMC na kayan haƙar ma'adinai da haɗin kaizoben zamewa mai hana ruwa da ƙurafasaha. Bayanan gwaji na ainihi sun nuna cewa matsakaicin lokacin da ke tsakanin gazawar kayan aiki (MTBF) bayan canjin ya ƙaru daga awanni 1800 zuwa awanni 5200, wanda hakan ya samar da kyakkyawan tushe don sauya ma'adanai cikin hikima.
