Mine ventilation fan silencer haisi yekuwedzera-icho chinhu chakakosha chinotarisa kana mugodhi uchisangana nemiganhu yeruzha rwepabasa, unodzivirira zvirango zvekutonga, uye unochengetedza vashandi vakasvinura kupfuura maawa gumi nemaviri. Takaona vashandi vepasi pevhu vachirondedzera tinnitus mushure memwedzi mitanhatu yekuratidzwa kune unmitigated fan ruzha pa92 dB (A); takayera madonhwe ekuyerera kwemhepo e18% apo masilencer aive akadzikiswa kana kusabatanidzwa zvisina kunaka mumadhiraini. Ndosaka mainjiniya kuZibo Hongcheng Fan Co., Ltd vachibata zvese mine ventilation fan silencer sechikamu chehurongwa-kwete bhokisi rakamira.
Sei MaSilencers Akajairwa Achikundikana Pazasi
Zvinyaradziso zvizhinji zviri kunze-pasherufu zvinotora kugadzikana kwemhepo, mweya wakachena wekupinda, uye tembiricha iri pasi pe40°C. Zvimbambaira hapana chimwe chazvo. Dust-laden airflow clogs absorptive media mumavhiki. Unyoro hwepamusoro hunoodza mabhatiri emukati. Kamwe kamwe kudzvinyirirwa kunowedzera kubva kuzviitiko zvinoputika zvinosimbisa majoini akasungwa. Uye nzvimbo dzinodzivirira kuputika dzinoda zvinhu zvisingapisi — dzimba dzealuminium dzine simbi isina tsvina, kwete kabhoni ine galvanized coating. Yedu FBD yakatevedzana mafeni anogara achimhanya pa3,200 Pa static pressure; silencers inofanirwa kubata izvo pasina resonance buildup kana kuyerera kuparadzaniswa. Mumwe mutengi muShanxi akatsiva generic silencer neyedu-yakagadzirwa unit-uye akacheka fan-yekupedzisira ruzha kubva 104 dB (A) kusvika 79 dB (A) ichichengetedza ± 1.2% kuyerera kwemhepo kunoenderana ne200-1,800 m³/min renji.
Zvina Zvisingataurwi Negotiable Design Criteria
A functional mine ventilation fan silencer inofanirwa kuzadzisa izvi maitiro mana-pasina kunze:
- Kuputika-proof certification: Zvese zvikamu zvemigodhi yemarasha zvinotakura dⅠ chiyero paGB 3836.1–2021; hapana kukanganisa pane spark-resistant fasteners kana kuenderera mberi kwepasi
- Dust resilience: Inotsiviwa acoustic modules ine 3mm-yakakora perforated Stainless simbi yakatarisana-yakaedzwa pa5 g/m³ guruva kurodha kwe500+ maawa.
- Thermal kugadzikana: Core baffles akatemerwa kuenderera mberi kwekushanda kusvika ku85 ° C, yakasimbiswa nemafuta ekufungidzira panguva ye72-awa yekuyedzwa kwemutoro.
- Pressure drop control: Max ΔP ≤ 85 Pa pakuyerera-kupfuura izvi kunomanikidza mafeni kushanda nesimba, kuwedzera kushandiswa kwesimba uye kupfeka kwemagetsi.
Isu tinosimbisa dhizaini yega yega tichishandisa ISO 7235 test protocol, kwete chete zvichemo zvemugadziri. Chaiyo-nyika data inonyanya kukosha kupfuura lab sheets.
Kubatanidzwa Ndiko uko Kuita Kunorasika-kana Kuhwina
Silencer inoshanda chete kana yakamira zvakanaka. Kuiisa yakananga painobuditsa fan inokonzeresa kusagadzikana iyo inosiya hafu yekudzikira kwayo. Isu tinotsanangura mashoma akatwasuka duct anomhanya: 5 pombi madhayamita kumusoro kwerwizi, 3 kuzasi. Kune mafani axial seFBD-NO.6.3 yedu, tinobatanidza silencer mu fan casing pachayo-kubvisa kurasikirwa kwekubatanidza uye kuderedza tsoka ne37%. Retrofit mapurojekiti anowanzo kutarisisa kutapurirana kwevibration: unisolated silencers inoshandura ductwork kuita maradiator anonzwika. Zvikamu zvedu zvinosanganisira mbiri-nhanho elastomeric mounts dzakayerwa 0.5–2,000 Hz yekuzviparadzanisa-inosimbiswa neaccelerometer kuverenga isati yaiswa uye mushure mekuiswa.
Kuisa hakusi plug-uye-kutamba. Isu tinopa saiti-yakatarwa torque specs, kushivirira kwekuenzanisa (± 0.15 mm), uye macheki ekutarisa. Imwe tunnel purojekiti muYunnan yakakundikana bvunzo dzeruzha rwekutanga nekuti mabhaudhi eanchor haana kuomeswa kusvika 75% simba regoho-zvichikonzera micro-kufamba uye gumi nemaviri dB re-radiation. Kugadzirisa? Retorque + wedzera shear pini. Zvakaitwa mumaminitsi makumi mapfumbamwe.
Customization Pasina Kukanganisa
Masilencer akajairwa haafanire kukwana zvimiro zvakaomarara. Takavaka mayunitsi ane offset inlets, 45° angled outlets, uye akabatanidzwa anodzima moto — zvese mukati memavhiki mana. Metallurgical client yaida corrosion resistance yeH₂S-rich exhaust: takashandisa titanium alloy baffles nePTFE-coated acoustic fill, kuwana 32 dB (A) kuisa kurasikirwa pa500 Hz tichirarama 1,200-awa yemunyu-spray test. Hapana stock chinhu chaigona kuita izvozvo. Tsika hazvirevi kunonoka. Yedu CNC-bent imba line inobata kusvika 2,000 mm dhayamita mayuniti; dynamic balancing inoitika mumba pane 3-ton-capacity rig. Yese unit inotakura ine yakazara mishumo yebvunzo: octave-bhendi attenuation curves, kudonhedza kudonhedza maringe nekuyerera machati, uye zvitupa zvezvinhu.
Zibo Hongcheng Fan Co., Ltd. inovaka mine ventilation fan silencer masisitimu-kwete zvikamu. Isu tinovagadzira kune kwavanozoshanda chaiko: kunyorova, kune guruva, kudzvanywa, kuchengetedzeka-kwakakosha nharaunda. Nekuti kunyarara pasi pevhu hakuna kunyarara - kuvimbika kwekushanda, kuchengetedzwa kwekunzwa, uye kusinga vhiringike kubuda kwemhepo.
