Mafanhi anoputika anodzivirira mhepo inoita kuti mhepo ifambe panogona kureva njodzi. Mumigodhi yemarasha, tunnels dzekugadzira makemikari, kana mikoto yebasa remumunda wemafuta, kufefetedza hakusi kwekunyaradza — ndezvekupona. Isu takaona mafeni achikundikana pasi pekupisa kwekupisa, kushata panguva yemethane spikes, kana corrode mushure memwedzi mitanhatu mumhepo ine sarufa. Ndicho chikonzero nei mainjiniya achitsanangura kuputika-chiratidzo tunnel fan unit kwete senge sarudzo-asi sechinhu chekutanga chinodiwa.
Nei Standard Tunnel Fans Vachikundikana munzvimbo dzine Njodzi
Kufefetedza kwenzvimbo ine ngozi kunoda kudarika kuyerera kwemhepo. Inoda kuchengetedzeka kwemukati-hapana kudzima sosi, hapana nzvimbo inopisa, hapana nzira yekuburitsa. Standard axial kana centrifugal tunnel mafeni anoshandisa induction motors ane pachena materminals, asina-vented housings, uye kabhoni brushes ayo arc. MuZone 1 (uko kungangoita gasi rinoputika) kana Zone 2 (kwavanopota neapo), izvo zvinhu zvinotyora IEC 60079-0 uye GB 3836.1 zviyero zvachose.
Takaedza matatu kubva-pasherufu tunnel mafeni mumhepo yakateedzerwa yemugodhi (5.5% CH₄, 22 ° C, 95% RH). Zvese zvakapfuura tembiricha yepasi mukati memaminitsi makumi mana nemanomwe. Zviviri zvakaputsika zvinopisa zvinopisa; imwe yakabatidza bvunzo gasi musanganiswa panguva yekutanga kuvhiya. Chikonzero chikuru? Zvisina-certified motor windings, ungrounded impeller hubs, uye zvisungo zvepurasitiki zvinogadzira electrostatic charge. Kukundikana kwepasirese hakusi kwekufungidzira-kwakanyorwa muChina's State Administration yeBasa Chengetedza chiitiko matanda kubva 2022-2023.
Chii Chinoita Yechokwadi Kuputika-Chiratidzo Tunnel Fan?
Iyo yakasimbiswa inoputika-inopikisa mugero fan inosanganisa mana asina-akurukurika akaturikidzana: mota yakavharirwa (dⅠ kana Ex d IIB T4), dhizaini yemajoini isingapindi moto (kwete "kudzivisa spark" chete), tembiricha-kirasi-yakafanana zvinhu, uye chiyero chesimba chakasimbiswa pa110% yakayerwa kumhanya. Iyo FBD yakatevedzana (dⅠ) inopokana-inotenderedza axial kuyerera feni-yakagadzirirwa zvakanangana yepasi pevhu yemarasha misoro-inoshandisa maviri maviri-asingaputi mota akaiswa muakavharirwa aruminiyamu akavharirwa ane 0.012 mm yakakura yakabatana gap. Mapombi ayo anomhanya pa1,480 rpm asi anogara ari pasi pe135 ° C pamusoro pekushisa kunyangwe pa105% mutoro. Iyo haisi kopi yekushambadzira-ndiyo yakayerwa data kubva kune yedu ISO 17025-yakatenderwa lab.
Asi certification chete haina kukwana. Isu takaona vatengi vachiisa mafeni ane certification kuti vawane kudonha kwemhepo nekuda kwekusapindirana kwe duct kuramba kana kudonha kwevoltage pa800-mita tambo inomhanya. Mhinduro yechokwadi inofanirwa kuverengera masisitimu-level zvinosiyana: static pressure curves, inlet turbulence, ambient humidity mhedzisiro pane motor insulation kuramba, uye harmonic kukanganisa kubva kusiyanisa-frequency dhiraivha. Ndosaka yega yega FBD unit inotakura nesaiti-yakanangana nekuita curve-kwete chete kataroji chati-uye inosanganisira terminal boxing grounding lugs size 35 mm² waya yemhangura.
Kugadzirisa Haisi Humbozha-Iko Kushanda Kunodiwa
Imwe-saizi-inokodzera-zvese haipo pasi pevhu. Iyo mugero feni ye3.2 m dhayamita yemarasha inokukurwa inoda kwakasiyana, ruzha chimiro, uye inokwirisa geometry pane imwe ye5.8 m kemikari yekudyara shaft. Isu takavaka anopfuura zana nemakumi manomwe nemana akasiyana-siyana mumwedzi yadarika makumi maviri nenomwe-kusanganisira titanium-bladed modhi yeH₂S-rich flue gasi ducts, maviri-inlet masisitimu emaseketi emhepo anopindirana, uye yakaderera-frequency-modulated shanduro inoderedza kuzunguzika kunonzwika mumadziro ematombo akavharidzirwa.
Kiyi yekugadziridza levers yatinogara tichiendesa:
- Motor winding class: H-class insulation standard, yakakwidziridzwa kuenda kuC-class ye> 200°C ambient application
- Impeller zvinhu: Aluminium alloy (standard), Stainless simbi 316 (chloride environments), kana Grade 7 titanium (H₂S + high velocity)
- Kudzora interface: RS-485 Modbus RTU pre-waya, 4-20 mA analogi mhinduro, kana hardwired emergency kumira kusanganisa
- Certification scope: Dual-yakasimbiswa kune ese ari maviri GB 3836 uye ATEX 2014/34/EU- yakasimbiswa neCNEX uye SGS
Hapana chirango chenguva yekutungamira chinoshanda. Yedu modular yekugadzira mutsara inobata gumi nemaviri epakati mota mafuremu, 8 impeller yekukanda mapatani, uye mashanu edzimba akasiyana-ese akafanoedzwa uye akanyorwa. Tsika dhizaini dzinokiya mukati machining asati atanga, kwete mushure megungano.
Kushanda Kwechokwadi Kunotanga Usati Waiswa
Delivery haina kupera. Isu takatsvaga nyaya dzepashure pekuisa mumasaiti makumi mana nerimwe: 62% yakateedzerwa kune isina kufanira ivhu, 23% kune yakaderera tambo dzemagetsi, uye 15% kuvharira mukati kunokonzerwa nekutadza dhizaini yekuchinja. Ndokusaka odha yega yega ichisanganisira yemahara application engineering rutsigiro-kwete chete maPDF manyoro. Chikwata chedu chinoongorora tunnel yako muchinjika-chikamu, inotarisirwa kuumbwa kwegasi, kugadzikana kwesimba remagetsi, uye zvimhingamipinyi zvekugadzirisa. Isu tinotevedzera kuora kwekuyerera kwemhepo mhiri kwe200+ metres edhivha uye njodzi yekudonha kwemureza usati wacheka kongiri.
Zibo Hongcheng Fan Co., Ltd. inovaka mauniti aya munzvimbo yayo ye9,000 m² Zibo Blower Industrial Park nzvimbo-uko fan yega yega inosangana nemaawa makumi manomwe nemaviri ekuyedzwa kwemutoro kuzere-yakaomerwa kumanikidzwa, ichiteverwa ne thermographic scanning uye chikamu chekubuda muyero. Unowana gwaro rebvunzo rakasainwa, kwete chitupa. Nekuti kana methane concentration ikarova 4.3%, chakakosha hakusi kutevedzera mapepa - ndezvekuti fan inoramba ichitenderera.
Kune mainjiniya anotsanangudza kuputika-chiratidzo chetunnel fan masisitimu, mubvunzo hausi "Ndeipi mhando?" "Ndeipi mudiwa anonzwisisa kuti kutadza kwemhepo haisi nguva yekudzikira-ingozi." Kunzwisisa ikoko kunogara mune weld seam kushivirira, iyo mota inomonereka dielectric simba, uye kugona kwenyanzvi kuona kuenderera kwepasi panzvimbo. Ndiko uko kuchengetedzeka kwechokwadi kunotanga-uye kwaisingafaniri kupera.
