Lapho ukugeleza komoya kwehluleka emhubheni, ukuphepha kwehluleka kuqala. Sikubonile kwenzeka: izinga lokushisa liyakhuphuka eduze kwendawo yokumbiwa, ukunqwabelana kwe-CO emigodini yokulungisa ujantshi, ukungenisa komoya omisiwe phakathi nokubhoboza izimo eziphuthumayo. Yingakho onjiniyela becacisa I-SDF Series Tunn Fan-hhayi njengesivutheli esijwayelekile, kodwa njengempendulo efakazelwe ensimini ezidingweni ezintathu okungaxoxiswana ngazo: ukuphokophela okuqhubekayo ekulahlekelweni kwengcindezi ephansi, ukusebenza okuzinzile ngaphansi kwezimo ezigcwele uthuli noma ezinomswakama, kanye nokungabekezeleli nhlobo ekubalekeni okushisayo. I-Zibo Hongcheng Fan Co., Ltd. idizayine lolu chungechunge kusukela phansi kuya phezulu ukuze lube nezindawo zangempela zomhubhe—hhayi imininingwane yelebhu.
Kungani Abalandeli Be-SDF Series Tunnel Beletha Lapho Abanye Behlala Khona
Ukungena komoya emhubheni akuphathelene nokunyakazisa umoya. Imayelana nokuhambisa *umoya ofanele*, *ngesivinini esilungile*, ngokusebenzisa *ukushintsha ukumelana*, *izinyanga ngaphandle kwesevisi*. Uchungechunge lwe-SDF luhlangabezana nalolo vivinyo ngabahlukanisi abathathu abangonjiniyela.
Okokuqala, i-impeller yayo enezigaba ezimbili ephikisayo iletha ukusebenza kahle kokucindezela okumile okuphezulu okungu-15–22% kunamafeni e-axial esiteji esisodwa ngokufaka amandla afanayo—okuqinisekiswa kuzo zonke izindawo ezingu-12 ezisetshenziswa esizeni emihubheni yokufinyelela emayini yamalahle eShandong. Okwesibili, ukwakhiwa kwezimoto kuhlanganisa ama-dust seal *kanye* ne-Class H, okuvumela ukusebenza okungaphazamiseki ku-45°C ambient + 85% RH—izimo lapho abalandeli abajwayelekile bekhubaza ukuvikeleka okushisayo ngemva kwamahora angu-72. Okwesithathu, iyunithi ngalinye lihamba ngamavane omhlahlandlela we-inlet akalwe ngaphambilini, okuvumela ukulungiswa kokugeleza komoya kusuka ku-60% kuye ku-100% umthamo ngaphandle kokulahlekelwa okudonsa kanzima noma ingozi yokuzwakala kwemisindo.
Asinciki kumajika ekhathalogi. Ngesikhathi sisebenza emhubheni onguthelawayeka ongu-3.2-km e-Gansu, silinganise ukumelana kwesistimu kwangempela ku-1,280 Pa—hhayi i-950 Pa ecatshangwa ngomklamo. Imodeli ye-SDF-16 igcine u-98.3% wokugeleza komoya okulinganiselwe ngaleso sikhathi. Abalandeli abaqhudelanayo behle bafinyelela ku-71%. Leyo imajini igcine amazinga ezinhlayiyana zedizili engaphansi kuka-0.05 mg/m³ ngesikhathi sokwakha.
Lokho Abasebenzisi Bangempela Abakulungisayo—nokuthi Kungani
Amaqembu okuthenga asibuza imibuzo emithathu ngaphambi koku-oda:
- "Ingakwazi ukumelana nokuguquguquka kwamandla kagesi?" Yebo—amamodeli avamile amukela ukuhluka okungu-±10% (380V ±38V) ngaphandle kokuhlehlisa. Amamojula angazikhethela aqala ngokuthambile anciphisa ukungena ngaphakathi ngo-65%, okubalulekile eziteshini ezingaphansi ezikude.
- “Ingabe sidinga ukuvikela ukuqhuma?” Kuphela uma i-methane >0.5% LEL ilindelwe. Emihubheni eminingi yomgwaqo/ojantshi, amayunithi e-SDF ajwayelekile ahlangabezana ne-GB/T 13306–2011 ezindaweni ezingenabungozi. Izinhlelo zokusebenza zemayini yamalahle zidinga okuhlukile kochungechunge lwe-FBD—umugqa womkhiqizo ohlukile, indlela ehlukile yokunikeza izitifiketi.
- “Singazithola ngokushesha kangakanani izinsimbi?” Amakhithi okuthwala, izisindo zokulinganisa i-impeller, nama-PCBs ephaneli yokulawula ahamba phakathi kwamahora angu-48 ukusuka e-Zibo. Akukho ukubambezeleka kokugcinwa kwempahla phesheya.
Ukwenza ngokwezifiso akuyona into edayiswa kakhulu—umkhuba ojwayelekile. Ngonyaka odlule, iphrojekthi kamasipala wase-Chengdu yayidinga amayunithi e-SDF-20 anezikhonkwane zensimbi engagqwali (316L), ama-shaft anwetshiwe okuhlanganisa ipayipi elinezindonga ezimbili, kanye nempendulo engu-4–20 mA ekuthwaleni izinga lokushisa. Ilethwa ngezinsuku eziyi-18. Akukho ukuklama kabusha. Isiyalo sobunjiniyela nje.
Ukufaka Okungokoqobo Kuhlola Iningi Lamashidi Akhethekile Awaziba
Ukukhweza kubaluleke ngaphezu kwamandla amahhashi. Sibone ukwehluleka okubili okuvela njalo:
Okokuqala, ukudluliselwa kokudlidliza ezindongeni zikamhubhe kakhonkolo lapho amapuleti ayisisekelo engenawo amaphedi okuhlukanisa ama-neoprene angu-12-mm. Umphumela: imifantu emincane kuma-shotcrete linings ngemva kwezinyanga eziyisi-6. Amayunithi e-SDF ahlanganisa ukucaciswa kwephedi kumanuwali yokufaka—hhayi njengombhalo waphansi, kodwa njengesinyathelo sesi-3 ngokulandelana kwetorque.
Okwesibili, ukuhlehliswa kwesiqondisindlela sokugeleza komoya ngenxa yejiyomethri engalungile yokuguqula ipayipi. Uchungechunge lwe-SDF lusebenzisa umaka wokuzungezisa kwesokunxele/kwesokudla ogxivizwe ngokuqondile ku-casing—hhayi nje amalebula. Siphinde sinikeze ngezifanekiso zokuqondanisa zokusikwa kwe-laser ukuze abafaki baqinisekise imigqa emaphakathi ye-inlet/outlet ngaphambi kokufaka ibhawudi.
Yonke iyunithi ithola ukulinganisela okuguquguqukayo komthwalo ogcwele ku-110% RPM endlini. Hhayi nje “ukulinganisela ku-G2.5”—sibhala i-vector esele engalingani (amagremu · mm) ku-rotor ngayinye. Leyo datha ihamba nefeni. Uma ukudlidliza kuphakama kamuva, onjiniyela benkambu baqhathanisa nesisekelo—hhayi ukuqagela.
Okubalulekile: Ukwethembeka Ongakukala
I-SDF yochungechunge lwe-tunnel fan ayichazwa nge-CFM ephezulu noma ukucindezela okukhulu okumile. Kuchazwa yilokho okungenzeki: akukho ukuvalwa okungahleliwe phakathi nenkathi yokuqapha yezinyanga eziyi-18, akukho ukungalingani kweblade okubangelwa ukugqwala emhubheni womoya kasawoti osogwini, akukho kulawulwa ukukhukhuleka ngemva kwemijikelezo yokuqala eyi-10,000 yokumisa.
I-Zibo Hongcheng Fan Co., Ltd. yakha laba balandeli endaweni yabo engu-9,000 m² i-Zibo Blower Industrial Park—indawo efanayo lapho yonke ingxenye yenziwa ngomshini, ibhalansile, ihlanganiswe, futhi ihlolwa ukulayisha. Awukho umhlangano wokugcina onenkontileka engaphansi. Akukho ukuyekwa kwekhwalithi ye-offshore. Wonke umlandeli uphethe ikhodi ye-QR exhuma embikweni wayo wokuhlola: ijika lokugeleza komoya, ileveli yokucindezela komsindo ku-1m, ukukhuphuka kwezinga lokushisa elithwalayo, kanye ne-amplitude yokudlidliza ku-mm/s RMS.
Uma iphrojekthi yakho elandelayo yomhubhe idinga ukugeleza komoya ongayethemba-hhayi nje ukubala-qala nge- I-SDF Series Tunn Fan. Ngoba ezikhaleni ezivalekile, kubalwa imizuzwana. Futhi ukwethembeka akusona isici. Kuyisisekelo.
