Tunnel ventilation haisi yekufambisa mhepo - ndeye kuponesa hupenyu, kudzivirira kukwira kwemoto, uye kuchengetedza kungwarira kwemutyairi munzvimbo dzakavharirwa, dzine njodzi huru. Kana utsi huchizadza 3-kilomita yemugwagwa mugero panguva yechiitiko, sekondi yega yega inoverengera. Ndosaka mainjiniya asingagadzirire mafeni egeneric. Vanotsanangura SDD Series Jet fan mayunitsi-chaiyo-engineered, thrust-optimized, uye munda-unoratidzwa pasi peiyo chaiyo-yenyika inopisa uye aerodynamic kusagadzikana.
Nei SDS Series Jet Mafeni Achiunza Chaiyo Tunnel Chengetedzo-Kwete Kungofamba Kwemhepo Nhamba
Takaona mapurojekiti akawandisa achikundikana-kwete kubva mukugadzirwa kwakashata, asi kubva pakusarudzwa kwefani. Fani ine chiyero che30,000 m³/h hairevi zvishoma kana trust coefficient yayo yadonha 18% pa55°C ambient kana kana blade resonance yayo ichienderana neakajairika traffic vibration frequencies. The SDD Series Jet fan inodzivirira njodzi idzi nekugadzira.
Imwe neimwe yuniti inoburitsa zvinotenderedza kutenderera kwese kwakazara kushanda renji: 1,800–4,200 N per feni, zvichienderana nemodhi uye mota kumisikidzwa. Kusiyana nemaaxial units ekare anorasikirwa nekubudirira pamusoro pe45 ° C, mafeni eSDS anoshandisa Class H insulation uye thermally stable composite blades-yakaedzwa nguva dzose pa 70 ° C inlet air kwemaawa makumi manomwe nemaviri pasina kuita kudonha. Isu takasimbisa izvi panguva ye2023 yekumisikidza bvunzo mumugero wegomo padhuze neLanzhou: matatu maSDS-1250 mayuniti akachengetedza 96.3% yeyakayerwa yekusundidzira mushure memaawa makumi mana nemasere ekushanda kunoramba kuchiita pa62 ° C ambient uye 85% hunyoro hunoenderana.
Kukwira kunokosha zvakangofanana nemoto specs. Mafeni eSDS anobatanidza ISO 10816-inoenderana vibration yekuzviparadzanisa yakananga mune yekutsigira furemu-hapana munda-welded mabhureki, hapana rabha pad kushatisa. Izvi zvinocheka nguva yekuisa ne 40% uye zvinobvisa chikonzero chakajairika chekutadza kubereka nguva isati yakwana mumashandisirwo etunnel: misalignment-induced dynamic loading.
Chii chinoita kuti SDS Fans Vashande uko Vamwe Vakamira-Chaizvo uye Nehunyanzvi
Vamwe vanogona kupokana kuti chero yakakwira-thrust axial fan inokwana pakushandisa tunnel. Nekudaro, chaiyo-yepasirese tunnel mhepo inoyerera haina kudzika-mamiriro-inoputika, asymmetric, uye yakasvibiswa. Diesel inogadzira majasi majasi. Kamwe kamwe mhiri kwemhepo inokonzera kuyerera kuparadzaniswa. Emergency mota ndima dzinogadzira transient backpressure spikes.
Iyo SDS yakatevedzana inobata ese ari matatu nekuti akavakirwa akatenderedza matatu asingataurwe maficha:
- Counter-inotenderera mbiri impellers-kwete chete yekusundidzira kwepamusoro, asi yekukurumidza kuyerera re-simba mushure mezvekutenderera nzvimbo;
- Yakabatanidzwa CFD-yakasimbiswa shroud geometry-kudzikisa kurasikirwa kwetip vortex ne22% kupesana ne-single-impeller dhizaini (pamunhu wechitatu-bato remhepo tunnel verification);
- Modular kuputika-proof mota sarudzo-yakasimbiswa kune GB 3836.1-2021 uye IEC 60079-0: 2017, ine sarudzo ATEX Zone 1/21 yekumaka yemakemikari ekutakura tunnel.
Isu takambotsiva vatanhatu vekuchembera 110 kW mafeni mumugero wemarasha wekutakura une mana SDS-1600 mayunitsi. Kushandiswa kwesimba kwakadzikira 31%, nguva dzekugadzirisa zvakapetwa kaviri, uye-zvinonyanya kukosha-iyo system ikozvino inotangazve mukati me2.3 seconds mushure mekukanganiswa kwemagetsi. Iko kumhanya kunokosha kana kufefetera kuchifanira kutangazve CO mazinga asati atyora 30 ppm.
Kugadzirisa Haisi Yehumbozha-Ndiyo Chinodiwa Chekutanga
Hapana mapatani maviri anogovana zvipingaidzo zvakafanana. Imwe inoda corrosion resistance against de-icing salt aerosols. Imwe inoda ma titanium blades ye sulfur-rich geothermal exhaust. Chechitatu chinoda kuongororwa kure kuburikidza neModbus TCP ine onboard tembiricha, vibration, uye kusunda kwekutarisa.
Zibo Hongcheng Fan Co., Ltd. inobata kugadzirisa seyakakosha maitiro-kwete yekuwedzera-basa. Yavo SDS yakatevedzana inopa:
- Zvitatu zvakajairwa magetsi sarudzo (380 V / 660 V / 1140 V), ese ane ± 10% kushivirira uye harmonic kusefa;
- Optional IP68-yakatemerwa junction mabhokisi ane silicone-yakavharwa tambo yekupinda;
- Blade zvinhu: aluminium alloy (yakajairwa), simbi isina tsvina 316L, kana giredhi 2 titanium yeH₂S kana chloride kuratidzwa;
- Kubatanidzwa kwakazara nemapuratifomu eBMS-kusanganisira rutsigiro rwemuno rweKNX, BACnet MS/TP, uye MQTT protocol.
Mutengi muJiangsu aida mafeni eSDS emugero wenjanji yepasi pegungwa umo mhute yemunyu inopinda yaipfuura 500 mg/m³/zuva. Standard epoxy coating yakundikana mumwedzi gumi nemana. Mhinduro yacho? Titanium blades + ceramic-coated motor housings + yakamanikidzwa kuchenesa mhepo zvisimbiso. Yakaunzwa mumavhiki e11-pasina kunonoka kutumirwa kwetunnel.
Kusarudza iyo Yakakodzera SDS Fan Zvinoreva Kubvunza Iyo Yakakodzera Mibvunzo Kutanga
Usati wataura chero SDD Series Jet fan, bvunza mutengesi wako iyi mibvunzo mishanu-uye kumbira mhinduro dzakanyorwa:
- Chii chakayerwa chekusvuuka kwekuora pa65°C uye 90% RH pamaawa 1,000?
- Unogona here kupa wechitatu-bato bvunzo mishumo inosimbisa kuburitsa ruzha ≤78 dB(A) pamamita matatu, yemahara-munda mamiriro?
- Iwe unosimbisa sei kuvimbika kwechimiro cheSeismic Zone 8 (0.3g yakachinjika kukwirisa)?
- Ndeipi inoreva nguva pakati pekutadza (MTBF) yemota iri pasi pekuenderera 24/7 kushanda?
- Iwe unopa pa-saiti yekumisikidza tsigiro-kusanganisira kuyerera kwemhepo mepu uye thrust calibration verification?
Zibo Hongcheng Fan Co., Ltd. inotsikisa data rese rebvunzo zviri pachena. Zvinyorwa zvavo zveSDS zvakatevedzana zvinosanganisira kwete chete static performance curves-asi anesimba emhinduro machati anoratidza kusimudzira kudzoreredza nguva mushure mekuchinja kwe0-100% mutoro nhanho, uye mishumo yekufungidzira inopisa inosimbisa nzvimbo dzehotspot panguva yekuyedzwa kwekuremerwa.
Tunnel kuchengetedza inoshanduka. Saizvozvo tekinoroji yekufefetera inofanirwa. The SDD Series Jet fan haingori imwe mutsara wechigadzirwa - ndiwo mhedzisiro yemakumi maviri emakore emhinduro yemumunda, iterative thermal modelling, uye zero-compromise kugadzira chirango. Kana hupenyu hunoenderana nekuyerera kwemhepo, kuvimbika hakuyerwe mune zvakatemwa. Zvinoratidzwa mumatanho akazara nehutsi, pa3 am, panguva yemhepo yakaipisisa yegore.
