Kuchita kwa mafani ozimitsa moto sikuyezedwa ndi ma decibel kapena ma curve oyenda mpweya okha—amayezedwa mumasekondi opulumutsidwa, kubwezeretsedwa kwa mawonekedwe, ndi kutetezedwa miyoyo. Utsi ukatsamwitsa makwerero, n’kudzaza mumphangayo, kapena kubisala m’chipinda chosungiramo mankhwala, mpweya wabwino umalephera. Zomwe zimagwira ntchito zimakhala ndi cholinga wozimitsa moto: kuchuluka kwambiri, kutumizidwa mwachangu, kupangidwira chipwirikiti-osati chitonthozo.
Chifukwa chiyani "Kuchotsa Utsi Mofulumira" Kumafunikira Zambiri Kuposa CFM Yokha
Taziwona patsamba lino: ogwira ntchito akutulutsa ma ducts a mita 30 kuti angopeza mafani awo a 15,000 CFM akuyimilira pa 40% yotulutsa chifukwa kupsinjika kwam'mbuyo kunakwera pafupi ndi khomo lamoto. Mpweya wozimitsa moto wapadziko lonse lapansi umalephera osati kuchokera kuzinthu zochepa-koma kuchokera ku mapangidwe osagwirizana. A zoona wozimitsa moto ayenera kupereka zinthu zitatu nthawi imodzi: kuthamanga kwa static (kukankhira mpweya kudzera munjira zazitali, zopindika), torque yomweyo (palibe kuchedwetsa kokwera pamene mphamvu igunda), ndi kulekerera kwamphamvu kwamafuta (imathamangabe pa 80°C mozungulira, osati 40°C yokha).
Mndandanda wa FBD (dⅠ) wotsutsa-kuphulika wotsutsana ndi axial flow fan-woyesedwa m'munda wopulumutsira migodi ya malasha-umasonyeza izi. Kapangidwe kake ka ma motor-motor, ozungulira mozungulira amatulutsa 3,200 Pa static pressure pa 22,000 m³/h. Izi sizongoyerekeza. Mu 2023 choyerekeza moto mumphangayo ku Shandong, idachotsa 90% ya utsi wowoneka kuchokera pagawo la mita 180 mkati mwa masekondi 97 - ndikusunga mpweya wokhazikika ngakhale kutentha kwalowera mpaka 120 ° C. Mafani a axial okhazikika adatsamwitsidwa pa 65 ° C.
Zomwe Zimapangitsa Wokonda "Fire Scene Ready" -Osati "Garedhi Yamakampani"
Opanga ena amatcha fani iliyonse yolemetsa ngati "yozimitsa moto." Ndiko kuchulukitsa kowopsa. Kuwotcha mpweya woyaka moto kumafuna malonda opambana kwambiri:
Chitsimikizo chotsimikizira kuphulika sichosankha-ndizosakambirana m'malo oyaka nthunzi. Chiyerekezo cha dⅠ chimakwirira malo a fumbi la methane/malasha pa GB 3836.1-2021, osati kungolemba kuti "otetezeka". Kulemera poyerekeza ndi kutumizidwa: Chowuzira chapakati cha 120 kg chikhoza kusuntha mpweya wochulukirapo-koma ngati ozimitsa moto awiri sangathe kuwukweza pagalimoto ya makwerero pansi pa masekondi 45, ndizopanda ntchito. Zofunikira kwambiri zautumwi wozimitsa moto mayunitsi amakhala pansi pa 42 kg popanda kupereka nsembe kukhulupirika. Mawonekedwe a duct amafunikira kwambiri kuposa mphamvu zamahatchi. Tasintha mafani ndi zofananira koma mawonekedwe osiyanasiyana a flange - ndikudula nthawi yokhazikitsa ndi 60%. Kulumikizana mwachangu, kokhotakhota, kodzisindikizira kumachotsa kutayikira komwe kumatulutsa magazi 25-40% ya mpweya wabwino. Ichi ndichifukwa chake Zibo Hongcheng Fan Co., Ltd. imaphatikiza kuyanjana kwa ma duct mu gawo lake la uinjiniya-osati ngati lingaliro lina. Mitundu yawo ya FBD imatumiza ndi mbale zoyimilira za ISO 5211 komanso makola oyimira 630 mm. Palibe ma adapter. Palibe kusintha kwamunda.
Kusintha Mwamakonda Sikosangalatsa - Ndi Kusiyana Pakati pa "Ntchito" ndi "Kusunga"
"Off-the-shelefu" nthawi zambiri samagwirizana ndi zochitika zamoto. Malo oyeretsera amafunika kukana dzimbiri polimbana ndi utsi wodzaza ndi H₂S. Chigayo chimafuna zopangira aluminium zosagwira moto. Sitima yapansi panthaka imafuna kuti phokoso likhale lotsika kwambiri pansi pa 72 dB(A) pamtunda wa mamita atatu—popanda kudula mpweya wotuluka.
Wothandizira m'modzi - gulu lozimitsa moto la tauni ku Jiangsu - amafunikira a wozimitsa moto zomwe zimatha kuthamanga mosalekeza kwa maola 4 pa 100% katundu ndikupulumuka mobwerezabwereza pamadzi. Nyumba zokhazikika za IP54 zidalephera mkati mwa mphindi 90. Njira yothetsera vutoli? Nyumba yopangidwa ndi titaniyamu (yopanda titaniyamu—yoletsa mtengo), zosindikizira zamagalimoto zovoteledwa ndi IP67, ndi zomangira zitsulo zosapanga dzimbiri. Imaperekedwa m'masiku 11 ogwira ntchito. Kuyesedwa pamizere ya mphindi 120 yakumiza. Ndikugwirabe ntchito pambuyo pa miyezi 18.
Kuthekera kumeneku kumachokera ku makina amkati, kusanja kwamphamvu, ndi kuyesa katundu - zonse pansi pa denga limodzi. Palibe kuchedwa kwa outsourcing. Palibe kusokonekera pakati pa zojambula zauinjiniya ndi gawo lomaliza.
Kusankha Chowotcha Chanu Chotsatira Chozimitsa Moto: Macheke Atatu Osakambirana
Musanasaine pagawo lililonse, tsimikizirani izi—papepala komanso pamaso panu:
Static pressure curve pa 100% RPM, osati pachimake CFM. Funsani tchati chonse cha PQ-osati mutu wa mutu. Ngati sagawana, chokanipo. Zowona zapadziko lonse lapansi za kuchepa kwa kutentha: Kodi kutuluka kwa mpweya kumatsika bwanji pa 70 ° C pozungulira? Pa 100 ° C? Osati "kuyesedwa mpaka 100 ° C" - koma "amasunga ≥92% ovotera mpweya pa 100 ° C ambient kwa mphindi 120." Zolemba za utumiki wakumunda: Kodi buku lokonza zokonza limalembera ozimitsa moto—osati akatswiri a m’fakitale? Kodi zikuphatikiza ma torque pa chomangira chilichonse, kulolerana kwa ma duct, ndi zowunikira zolephera (mwachitsanzo, "kugwedezeka pamwamba pa 4.2 mm/s RMS pa 1,750 rpm = kuvala> 15%)? A wozimitsa moto sikuti ndi "zida chabe." Ndi mphamvu yochulukitsa. Imatembenuza kutopa kwa kutentha kukhala kutuluka koyendetsedwa. Imasintha mawonekedwe a zero kukhala zowonera. Zimapatsa otsogolera zochitika mphindi - osati masekondi - kuti asankhe.
Zibo Hongcheng Fan Co., Ltd. amawamanga motere-osati mwatchutchutchu, koma zenizeni zenizeni. Njira yawo ikuwonetsa chowonadi chosavuta: masekondi akawerengera, kudalirika sizinthu. Ndilo metric yokha yomwe ili yofunika.
