Mpweya wabwino wa ngalande sikutanthauza kusuntha mpweya—ndiko kupulumutsa miyoyo, kuletsa kukwera kwa moto, ndi kukhala tcheru ndi madalaivala m’malo otsekeredwa, omwe ali pachiwopsezo chachikulu. Utsi ukadzadza mumsewu wamakilomita atatu pazochitika, sekondi iliyonse imawerengera. Ichi ndichifukwa chake mainjiniya samakhazikika kwa mafani a generic. Iwo amanena SDS mndandanda wa jet fan mayunitsi - opangidwa mwaluso, okhathamiritsa, komanso otsimikiziridwa m'munda pansi pa kupsinjika kwapadziko lapansi komwe kumatenthedwa ndi kutentha ndi mpweya.
Chifukwa chiyani ma SDS Series Jet Fans Amapereka Chitetezo Chenicheni cha Tunnel-Osati Nambala Zakutuluka Kwa Air
Tawona mapulojekiti ambiri akulephera-osati kuchokera ku mapangidwe olakwika, koma kuchokera ku kusankha kosagwirizana ndi mafani. Fani yofikira pa 30,000 m³/h sizitanthauza kuti mphamvu yake ikatsika ndi 18% pa 55°C mozungulira kapena ngati kamvekedwe kake kamayenderana ndi kugwedezeka komwe kumachitika kawirikawiri. The SDS mndandanda wa jet fan amapewa misampha imeneyi mwa kupanga.
Chigawo chilichonse chimapereka chiwongolero chokhazikika pamayendedwe onse: 1,800–4,200 N pa fani iliyonse, kutengera mtundu ndi kasinthidwe ka mota. Mosiyana ndi ma axial mayunitsi akale omwe amalephera kugwira ntchito bwino kuposa 45 ° C, mafani a SDS amagwiritsa ntchito kutsekereza kwa Class H ndi masamba osakanikirana otenthetsera omwe amayesedwa mosalekeza pa 70 ° C mpweya wolowera kwa maola 72 osasunthika. Tidatsimikizira izi poyesa mayeso a 2023 mumsewu wamapiri pafupi ndi Lanzhou: mayunitsi atatu a SDS-1250 adasunga 96.3% ya kulimbikira pambuyo pa maola 48 akugwira ntchito mosalekeza pa 62 ° C mozungulira ndi 85% chinyezi chachibale.
Kukwera kumafunikanso chimodzimodzi monga momwe zimakhalira motere. Mafani a SDS amaphatikiza kudzipatula kwa ISO 10816-yogwirizana ndi vibration mwachindunji mu chimango chothandizira-palibe mabulaketi otchinga m'munda, palibe kuwonongeka kwa rabara. Izi zimadula nthawi yoyika ndi 40% ndikuchotsa chomwe chimayambitsa kulephera kubereka msanga m'makina: kuyika molakwika-kupangitsa kuti pakhale mphamvu.
Zomwe Zimapangitsa Mafani a SDS Kugwira Ntchito Komwe Ena Amayimilira - Kwenikweni komanso mwaukadaulo
Ena angatsutse kuti fan iliyonse yothamanga kwambiri imakwanira kugwiritsa ntchito ngalande. Komabe, mpweya weniweni wapadziko lapansi siwokhazikika - umakhala wothamanga, wosawoneka bwino, komanso woipitsidwa. Dizilo imatulutsa mabala a malaya. Kuwombana kwadzidzidzi kumapangitsa kupatukana kwamadzi. Njira zamagalimoto angozi zimapanga ma spikes osakhalitsa.
Mndandanda wa SDS umagwira zonse zitatu chifukwa zimamangidwa mozungulira zinthu zitatu zomwe sizingakambirane:
- Zotengera zozungulira ziwiri-osati kungokankhira kwakukulu, koma kutulutsanso mphamvu mwachangu pambuyo pozunguliranso;
- Integrated CFD-yovomerezeka shroud geometry-kuchepetsa kutayika kwa nsonga ya vortex ndi 22% motsutsana ndi mapangidwe a choyikapo chimodzi (pa kutsimikizira kwa mphepo yamkuntho);
- Zosankha zamagalimoto zosagwirizana ndi kuphulika-yotsimikizika ku GB 3836.1-2021 ndi IEC 60079–0:2017, yokhala ndi chizindikiro cha ATEX Zone 1/21 pamachubu oyendera mankhwala.
Nthawi ina tidasintha mafani okalamba asanu ndi limodzi a 110 kW mumsewu wonyamula malasha wokhala ndi magawo anayi a SDS-1600. Kugwiritsa ntchito mphamvu kwatsika ndi 31%, nthawi yokonza idakwera kawiri, ndipo - movutikira - dongosololi liyambiranso mkati mwa masekondi 2.3 pambuyo pa kutha kwa magetsi. Kuthamanga kumeneku kumakhala kofunikira pamene mpweya uyenera kuyambiranso milingo ya CO isanaphwanyike 30 ppm.
Kusintha Mwamakonda Sizinthu Zapamwamba-Ndizofunika Kwambiri
Palibe ma tunnel awiri omwe amagawana zopinga zofanana. Imodzi imafunikira kukana dzimbiri motsutsana ndi ma aerosol amchere a de-icing. Wina amafunikira masamba a titaniyamu kuti apange utsi wochuluka wa sulfure wa geothermal. Chachitatu chimafuna kuzindikiridwa kwakutali kudzera pa Modbus TCP yokhala ndi kutentha kwapamtunda, kugwedezeka, komanso kuwunikira.
Zibo Hongcheng Fan Co., Ltd. Mndandanda wawo wa SDS umapereka:
- Zosankha zitatu zamagetsi (380 V / 660 V / 1140 V), zonse zokhala ndi ± 10% kulolerana ndi kusefa kwa harmonic;
- Mabokosi ophatikizika a IP68 okhala ndi zingwe zomata silikoni;
- Zida zamasamba: aluminium alloy (standard), chitsulo chosapanga dzimbiri 316L, kapena giredi 2 titaniyamu kwa H₂S kapena kukhudzana kwa chloride;
- Kuphatikizika kwathunthu ndi nsanja za BMS-kuphatikiza thandizo lakwawo la KNX, BACnet MS/TP, ndi ma protocol a MQTT.
Makasitomala ku Jiangsu amafunikira mafani a SDS kuti akwere njanji yapansi pa nyanja pomwe chifunga cha mchere chimadutsa 500 mg/m³/tsiku. Kupaka kokhazikika kwa epoxy kunalephera m'miyezi 14. Njira yothetsera vutoli? Masamba a Titaniyamu + ma mota okhala ndi ceramic okhala ndi zida + zosindikizira zosindikizira mpweya. Imaperekedwa m'masabata 11 - osachedwetsa kuyimitsidwa kwa ngalande.
Kusankha Woyimira Woyenera wa SDS Kumatanthauza Kufunsa Mafunso Oyenera Choyamba
Musanatchule chilichonse SDS mndandanda wa jet fan, funsani wogulitsa wanu mafunso asanu awa-ndipo funsani mayankho olembedwa:
- Kodi 65 ° C ndi 90% RH pa maola 1,000 ndi chiyani?
- Kodi mungapereke malipoti a chipani chachitatu otsimikizira kutulutsa phokoso ≤78 dB(A) pa 3 metres, malo aulere?
- Kodi mumatsimikizira bwanji kusasinthika kwa seismic Zone 8 (0.3g horizontal acceleration)?
- Kodi nthawi yotani pakati pa zolephera (MTBF) ya injini yogwira ntchito mosalekeza 24/7?
- Kodi mumapereka chithandizo chapatsamba - kuphatikiza mapu akuyenda kwa mpweya ndi kutsimikizira kuwongolera?
Zibo Hongcheng Fan Co., Ltd. Zolemba zawo zamtundu wa SDS sizimangokhala ma curve okhazikika - koma ma chart oyankha osinthika omwe akuwonetsa nthawi yochira pambuyo pakusintha kwa 0-100%, komanso malipoti oyerekeza otenthetsera omwe amatsimikizira malo omwe ali ndi hotspot pakuyesa mochulukira.
Chitetezo changacho chimasinthika. Momwemonso ukadaulo wa mpweya wabwino. The SDS mndandanda wa jet fan si mzere wina wazinthu - ndi zotsatira za zaka makumi awiri za ndemanga zakumunda, kufananiza kwamafuta obwerezabwereza, komanso kuwongolera zopanga ziro. Pamene miyoyo imadalira kayendedwe ka mpweya, kudalirika sikuyesedwa mwatsatanetsatane. Zimatsimikiziridwa muzitsulo zodzaza utsi, pa 3 koloko m'mawa, m'nyengo yamkuntho yoopsa kwambiri ya chaka.
