Mine ventilation fan silencer sikungowonjezera-ndi chinthu chofunikira kwambiri chomwe chimatsimikizira ngati mgodi umakwaniritsa malire a phokoso la ntchito, kupeŵa zilango zamalamulo, ndikukhala tcheru kwa ogwira ntchito pakusintha kwa maola 12. Tawonapo antchito apansi panthaka akufotokoza tinnitus pambuyo pa miyezi isanu ndi umodzi ya kuwonekera kwa phokoso losasunthika la fan pa 92 dB (A); tidayezera kutsika kwa mpweya wa 18% pomwe zotsekereza zidachepetsedwa kapena zosaphatikizidwa bwino ndi ma ductwork. Ichi ndichifukwa chake mainjiniya ku Zibo Hongcheng Fan Co., Ltd mine mpweya fan silencer monga gawo la dongosolo-osati bokosi loyima.
Chifukwa Chake Ma Silencers Okhazikika Amalephera Mobisa
Ma silencer ambiri omwe sali pashelefu amakhala ndi kachulukidwe ka mpweya wokhazikika, mpweya wabwino wolowa, komanso kutentha kozungulira pansi pa 40°C. Migodi sapereka iliyonse ya izo. Mpweya wodzaza ndi fumbi umatsekereza zotengera zomwe zimayamwa m'masabata. Chinyezi chambiri chimawononga zosokoneza zamkati. Kuthamanga kwadzidzidzi kuchokera ku zochitika za kuphulika kumagogomezera mfundo zowotcherera. Ndipo madera omwe sangaphulike amafunikira zida zosapsa—zinyumba za aluminiyamu zokhala ndi zitsulo zosapanga dzimbiri, osati chitsulo cha kaboni chokhala ndi malata. Otsatira athu a FBD amathamanga pafupipafupi pa 3,200 Pa static pressure; zoziziritsa kukhosi ziyenera kuthana ndi izi popanda kupangika kwa resonance kapena kupatukana. Makasitomala m'modzi ku Shanxi adalowa m'malo mwa silencer ndi gulu lathu lopangidwa mwamakonda-ndikudula phokoso lomaliza kuchokera ku 104 dB(A) mpaka 79 dB(A) kwinaku akusunga ± 1.2% kusasinthasintha kwa mpweya kudutsa 200-1,800 m³/min.
Zoyenera Zinayi Zosakambirana
A magwiridwe antchito mine mpweya fan silencer ziyenera kukwaniritsa zofunikira zinayi izi-osapatulapo:
- Chitsimikizo chosaphulika: Magawo onse a migodi ya malasha amakhala ndi dⅠ mlingo pa GB 3836.1–2021; palibe kunyengerera pa zomangira zosagwira moto kapena kupitilirabe pansi
- Kupirira fumbi: Ma module acoustic osinthika okhala ndi chitsulo chosapanga dzimbiri cha 3mm-thick perforated-oyesedwa pa 5 g/m³ pakupanga fumbi kwa maola 500+
- Kukhazikika kwamafuta: Mabaffle apakati adavotera kuti azigwira ntchito mosalekeza mpaka 85 ° C, zotsimikiziridwa ndi kujambula kwamafuta pakuyesa kwa maola 72
- Pressure drop control: Max ΔP ≤ 85 Pa pamayendedwe ovotera-kupitilira izi kukakamiza mafani kuti azigwira ntchito molimbika, kuwonjezera kugwiritsa ntchito mphamvu ndi kuvala kwamakina
Timatsimikizira kamangidwe kalikonse pogwiritsa ntchito ma protocol a ISO 7235, osati kungonena za opanga. Zambiri zapadziko lapansi ndizofunikira kwambiri kuposa mapepala a labu.
Kuphatikiza Ndiko Komwe Kuchita Kumatayika-kapena Kupambana
Silencer imagwira ntchito pokhapokha itayikidwa bwino. Kuyiyika molunjika ku chotengera cha fan kumayambitsa chipwirikiti chomwe chimalepheretsa theka la kuchepetsedwa kwake. Timalongosola njira zowongoka zosachepera: 5 mapaipi awiri kumtunda, 3 kutsika. Kwa mafani a axial monga FBD-NO.6.3 yathu, timagwirizanitsa silencer mu fan casing yokha-kuchotsa zowonongeka zowonongeka ndi kuchepetsa mapazi ndi 37%. Mapulojekiti obwezeretsanso nthawi zambiri amayang'ana kufalikira kwa kugwedezeka: zolumikizira zolumikizira zokha zimasandutsa ma ductwork kukhala ma radiator amawu. Mayunitsi athu amaphatikiza zokwera zapawiri za elastomeric zomwe zidavotera kudzipatula kwa 0.5–2,000 Hz—zotsimikiziridwa ndi zowerengera za accelerometer isanakhazikitsidwe komanso itatha.
Kukhazikitsa si pulagi-ndi-sewero. Timapereka ma torque okhudzana ndi tsamba lawebusayiti, kulolerana kwamayendedwe (± 0.15 mm), ndi mindandanda yoyang'anira. Pulojekiti imodzi ya tunnel ku Yunnan inalephera kuyesa phokoso loyamba chifukwa ma bolts a nangula sanasunthike mpaka 75% kuti azitha kutulutsa mphamvu - kuchititsa kuyenda kwazing'ono ndi 12 dB kuyambiranso. Konzani? Retorque + onjezani zikhomo zometa ubweya. Zachitika mu mphindi 90.
Kusintha Mwamakonda Popanda Kunyengerera
Silencer wamba sakhala wokwanira masanjidwe ovuta. Tapanga mayunitsi okhala ndi zolowera zolowera, zolowera 45°, ndi zozimitsa moto zophatikizika - zonse mkati mwa milungu inayi. Makasitomala opangira zitsulo amafunikira kukana dzimbiri chifukwa cha mpweya wochuluka wa H₂S: tidagwiritsa ntchito titanium alloy baffles okhala ndi PTFE-coated acoustic fill, kukwaniritsa kutayika kwa 32 dB(A) pa 500 Hz ndikupulumuka kuyezetsa kothira mchere kwa maola 1,200. Palibe katundu amene angachite zimenezo. Mwambo sikutanthauza kuchedwa. Mzere wathu wa CNC-wopindika wa nyumba umagwira mpaka mayunitsi a 2,000 mm awiri; dynamic balancing zimachitika mnyumba pa 3-ton-capacity rig. Chigawo chilichonse chimatumiza malipoti oyeserera: ma octave-band attenuation curve, kutsika kwamphamvu motsutsana ndi ma chart oyenda, ndi certification.
Malingaliro a kampani Zibo Hongcheng Fan Co., Ltd mine mpweya fan silencer machitidwe - osati zigawo. Timawapangira momwe angagwirire ntchito: konyowa, fumbi, kupanikizika kwambiri, malo otetezeka kwambiri. Chifukwa kukhala chete mobisa sikuli chete—ndiko kudalirika kwa kachitidwe, chitetezo cha kumva, ndi kutuluka kwa mpweya kosalekeza.
