Mine ventilation fan Silencer tsis yog ib qho ntxiv-nws yog ib qho tseem ceeb uas txiav txim siab seb lub mine puas ua tau raws li cov kev txwv tsis pub ua haujlwm, zam kev nplua, thiab txhawb nqa cov neeg ua haujlwm ceeb toom dhau 12 teev ua haujlwm. Peb tau pom cov neeg ua haujlwm hauv av tshaj tawm tinnitus tom qab rau lub hlis ntawm kev cuam tshuam rau cov kiv cua tsis muaj suab nrov ntawm 92 dB(A); peb tau ntsuas cov cua ntws poob ntawm 18% thaum cov silencers tau undersized los yog tsis zoo ua ke rau hauv ductwork. Tias yog vim li cas engineers ntawm Zibo Hongcheng Fan Co., Ltd. kho txhua tus kuv lub qhov cua ntxuam silencer raws li ib feem ntawm lub system - tsis yog ib lub thawv standalone.
Vim li cas Standard Silencers Fail Underground
Feem ntau cov silencers tawm ntawm lub txee xav tias huab cua ruaj khov, huab cua huv huv, thiab huab cua kub qis dua 40 ° C. Mines xa tsis muaj leej twg. Plua plav-laden airflow clogs absorptive media hauv lub lis piam. High humidity corrodes sab hauv baffles. Sudden siab surges los ntawm blast txheej xwm ntxhov siab welded pob qij txha. Thiab qhov chaw tawg-pov thawj xav tau cov ntaub ntawv tsis muaj teeb meem - txhuas vaj tse nrog stainless hlau sab hauv, tsis yog carbon hlau nrog galvanized txheej. Peb cov kiv cua FBD series ib txwm khiav ntawm 3,200 Pa zoo li qub; silencers yuav tsum daws qhov ntawd tsis muaj resonance buildup lossis ntws sib cais. Ib tus neeg siv khoom hauv Shanxi tau hloov lub tshuab ua suab nrov nrog peb cov kev cai tsim-thiab txiav cov kiv cua-kawg lub suab nrov ntawm 104 dB(A) mus rau 79 dB(A) thaum tuav ± 1.2% airflow sib xws thoob plaws 200-1,800 m³ / min ntau yam.
Plaub Qhov Kev Tsim Qauv Tsis Sib Tham
Ib tug haumxeeb kuv lub qhov cua ntxuam silencer yuav tsum ua kom tau raws li plaub yam no - tsis muaj kev zam:
- Cov ntaub ntawv pov thawj tawg: Txhua chav rau cov mines thee nqa dⅠ ntsuas ib GB 3836.1–2021; tsis muaj kev cuam tshuam ntawm cov hluav taws-resistant fasteners lossis grounding continuity
- Plua plav resilience: Hloov acoustic modules nrog 3mm-tuab perforated stainless hlau ntsia-kuaj ntawm 5 g / m³ plua plav loading rau 500+ teev
- Thermal stability: Core baffles ntsuas rau kev ua haujlwm tas mus li 85 ° C, validated los ntawm thermal imaging thaum 72-teev load test
- Kev tswj kev poob siab: Max ΔP ≤ 85 Pa ntawm qhov ntsuas ntws - dhau qhov no quab yuam cov kiv cua kom ua haujlwm hnyav, nce kev siv zog thiab kev siv tshuab
Peb lees paub txhua tus qauv siv ISO 7235 cov txheej txheem xeem, tsis yog cov neeg tsim khoom thov. Cov ntaub ntawv tiag tiag hauv ntiaj teb tseem ceeb tshaj li cov ntawv kuaj.
Kev sib koom ua ke yog qhov kev ua tau zoo ploj-lossis yeej
Lub suab ntsiag to ua haujlwm tsuas yog thaum nws raug tso. Mounting nws ncaj qha rau ntawm qhov hluav taws xob kiv cua tsim turbulence uas negates ib nrab ntawm nws attenuation. Peb qhia kom meej yam tsawg kawg nkaus txoj kab ncaj nraim khiav: 5 yeeb nkab diameters upstream, 3 downstream. Rau cov kiv cua axial zoo li peb FBD-NO.6.3, peb muab cov twj tso kua mis tso rau hauv cov kiv cua ntawm nws tus kheej-tso tawm kev sib txuas ntawm qhov poob thiab txo hneev taw los ntawm 37%. Retrofit tej yaam num feem ntau saib xyuas kev vibration kis tau tus mob: unisolated silencers tig ductwork rau hauv suab radiators. Peb cov chav muaj xws li dual-theem elastomeric mounts ntsuas rau 0.5-2,000 Hz kev rho tawm - txheeb xyuas los ntawm accelerometer nyeem ua ntej thiab tom qab kev teeb tsa.
Installation tsis yog plug-and-play. Peb muab qhov chaw tshwj xeeb torque specs, alignment tolerances (± 0.15 mm), thiab commissioning checklists. Ib qhov project hauv Yunnan ua tsis tau tiav qhov kev sim suab nrov vim tias cov pob txha thauj tog rau nkoj tsis tensioned rau 75% yield zog-ua rau micro-tsav thiab 12 dB re-radiation. Kho? Retorque + ntxiv shear pins. Ua tiav hauv 90 feeb.
Customization Tsis muaj kev cuam tshuam
Standard silencers tsis tshua haum cov layouts. Peb tau tsim cov chav nrog offset inlets, 45 ° angled outlets, thiab integrated hluav taws dampers - tag nrho nyob rau hauv 4 lub lis piam. Ib tus neeg siv khoom siv hlau xav tau kev tiv thaiv corrosion rau H₂S-nplua nuj tso pa: peb siv titanium alloy baffles nrog PTFE-coated acoustic sau, ua tiav 32 dB(A) ntxig poob ntawm 500 Hz thaum ciaj sia 1,200-teev ntsev-txhaj tshuaj ntsuam. Tsis muaj cov khoom lag luam tuaj yeem ua tau li ntawd. Kev cai tsis txhais hais tias ncua. Peb cov kab CNC-khoov vaj tse ua haujlwm txog li 2,000 hli txoj kab uas hla; dynamic balancing tshwm sim hauv tsev ntawm 3-tuj-muaj peev xwm rig. Txhua chav tsev xa khoom nrog cov ntawv qhia tag nrho: octave-band attenuation curves, siab poob vs. flow charts, thiab cov ntaub ntawv pov thawj.
Zibo Hongcheng Fan Co., Ltd kuv lub qhov cua ntxuam silencer systems - tsis yog cov khoom. Peb tsim lawv rau qhov chaw uas lawv yuav ua haujlwm tiag tiag: ntub dej, plua plav, siab-siab, kev nyab xeeb-tseem ceeb ib puag ncig. Vim hais tias nyob ntsiag to hauv av tsis nyob ntsiag to - nws yog kev ntseeg siab ntawm kev ua haujlwm, kev tiv thaiv kev hnov lus, thiab tsis muaj kev cuam tshuam huab cua.
