Xa ukuhamba komoya kungaphumeleli kwitonela, ukhuseleko lusilela kuqala. Siyibonile isenzeka: amaqondo obushushu anyukayo kufutshane nobuso bokomba, ukwakhiwa kweCO kwishafti zokulungisa umzila kaloliwe, ukungena komoya omileyo ngexesha loqheliso olungxamisekileyo. Yiyo loo nto iinjineli zicacisa I-SDF Sering Tunnel fan-kungekhona njenge-generic blower, kodwa njengempendulo eqinisekisiweyo yentsimi kwiimfuno ezintathu ezingenakuxoxisana: i-thrust eqhubekayo kwilahleko yoxinzelelo oluphantsi, umsebenzi ozinzileyo phantsi kweemeko ezinothuli okanye ezifumileyo, kunye nokunyamezela i-zero kwi-thermal runway. I-Zibo Hongcheng Fan Co., Ltd. yenzelwe olu chungechunge ukusuka phezulu ukuya phezulu ukuya kwindawo yokwenyani yetonela-hayi i-lab specs.
Kutheni le nto amaFani etonela yeSDF ehambisa apho abanye bahlala khona
Ukungenisa umoya kwitonela akukho malunga nokuhamba komoya. Kumalunga nokuhamba *umoya ochanekileyo*, kwisantya esifanelekileyo*, ngokutshintsha *ukumelana nokutshintsha*, kangangeenyanga * ngaphandle kwenkonzo *. Uthotho lweSDF ludibana nolo vavanyo kunye nezahlukanisi ezintathu zobunjineli.
Okokuqala, i-impeller yayo enemigangatho emibini ejikelezayo ihambisa i-15-22% ephezulu yoxinzelelo oluphezulu lwe-static kunabalandeli be-axial benqanaba elinye kwigalelo lamandla afanayo-aqinisekisiweyo kwi-12 kwi-site yokuthunyelwa kwindawo yokufikelela kwimigodi yamalahle yaseShandong. Okwesibini, i-motor housing idibanisa i-IP55 ye-dust seals * kunye ne-Insulation ye-Class H, eyenza umsebenzi ongaphazamisekiyo kwi-45 ° C ambient + 85% RH-imeko apho abalandeli abaqhelekileyo bahamba ngokukhuselwa kwe-thermal emva kweeyure ze-72. Okwesithathu, iyunithi nganye ihambisa i-vanes ye-inlet ye-pre-calibrated inlet, evumela ukulungiswa kokuhamba komoya ukusuka kwi-60% ukuya kwi-100% umthamo ngaphandle kokulahlekelwa yi-throttling okanye ingozi ye-resonance.
Asithembeli kwiikota zeekhathalogu. Ngexesha lokugunyaziswa kwi-tunnel ye-3.2-km e-Gansu, silinganise ukuchasana kwenkqubo yangempela kwi-1,280 Pa-kungekhona i-950 Pa ecingelwa kuyilo. Imodeli ye-SDF-16 igcine i-98.3% ye-airflow elinganisiweyo ngelo xesha. Abalandeli abakhuphisanayo behle baya kuma-71%. Lo mda wawugcina amanqanaba edizili engaphantsi kwe-0.05 mg/m³ ngexesha lonke lolwakhiwo.
Yintoni eJonga abasebenzisi bokwenyani-kwaye ngoba
Amaqela okuthenga abuza imibuzo emithathu ngaphambi koku-odola:
- "Ingakwazi ukumelana nokuhla kwamandla ombane?" Ewe-iimodeli eziqhelekileyo zamkela ± 10% ukuhluka (380V ± 38V) ngaphandle kokunciphisa. Iimodyuli ezikhethwayo zokuqalisa okuthambileyo zinqumle i-inrush yangoku ngama-65%, okubaluleke kakhulu kwizitishi ezikude.
- "Ngaba siyabufuna ubungqina bokudubula?" Kuphela ukuba kulindeleke imethane>0.5% LEL. Kwiitonela ezininzi zendlela/kaloliwe, iiyunithi zeSDF ezisemgangathweni zidibana ne-GB/T 13306–2011 kwiindawo ezingeyongozi. izicelo mgodini wamalahle zifuna FBD-series ezahlukeneyo-umgca imveliso eyahlukileyo, iindlela ezahlukeneyo isatifikethi.
- “Singazifumana ngokukhawuleza kangakanani izinto ezisetyenzisiweyo?” Izixhobo zokuthwala, iintsimbi zokulinganisa i-impeller, kunye nephaneli yolawulo yePCBs inqanawa phakathi kweeyure ezingama-48 ukusuka eZibo. Akukho kulibaziseka kogcino phesheya.
Ukwenza ngokwezifiso ayisiyonto yokuthengisa-yinto eqhelekileyo. Kunyaka ophelileyo, iprojekthi yemetro e-Chengdu yayidinga iiyunithi ze-SDF-20 ezine-cones zensimbi engenasici (316L), i-shafts eyandisiweyo yokudityaniswa kombhobho we-double-wall, kunye ne-4-20 mA ingxelo malunga nobushushu obuthwele. Ithunyelwe ngeentsuku ezili-18. Akukho ukuyila ngokutsha. Ingqeqesho nje yobunjineli.
UFakelo loNyaniso luJonga Uninzi lwaMashiti aKhethekileyo angahoyi
Ukunyuka kubaluleke ngaphezu kwamandla ehashe. Siye sabona ukusilela okuphindaphindiweyo okubini:
Okokuqala, ukuhanjiswa kwe-vibration kwiindonga zetonela yekhonkrithi xa iipleyiti ezisisiseko zingenazo iipads zokuhlukanisa i-12-mm neoprene. Isiphumo: iintanda ezincinci kwi-shotcrete linings emva kweenyanga ezi-6. Iiyunithi zeSDF zibandakanya ukucaciswa kweepadi kwincwadana yokufakela-kungekhona njengombhalo osezantsi, kodwa njengeNyathelo 3 ngokulandelelana kwetorque.
Okwesibini, isikhokelo sokuhamba komoya esibuyiselwe umva ngenxa yejiyometri yotshintsho lweduct engalunganga. Uthotho lweSDF lusebenzisa ukuphawula okujikelezayo ngasekhohlo/kwesokunene kufakwe isitampu ngokuthe ngqo kwi-casing-kungekhona nje iilebhile. Sikwabonelela ngeetemplates zolungelelwaniso ezisikwe ngelaser ukuze abafakeli baqinisekise imigca ephakathi yokungena/indawo yokuphuma phambi kokuba kufakwe ibhawuli.
Iyunithi nganye ifumana ulungelelwaniso oluguquguqukayo olugcweleyo kwi-110% RPM endlini. Akunjalo nje "i-balanced ukuya kwi-G2.5" -singena kwi-residual unbalance vector (grams·mm) kwi-rotor nganye. Loo datha ihamba kunye nefeni. Ukuba ukungcangcazela kuyenyuka kamva, iinjineli zangaphandle zithelekisa ngokuchasene nesiseko-hayi ukuqikelela.
Umgca ongezantsi: Ukuthembeka unokukukala
Umlandeli wetonela ye-SDF ayichazwanga yincopho yeCFM okanye uxinzelelo olukhulu. Ichazwa yinto engenzekiyo: akukho kuvalwa okungacwangciswanga kwiinyanga ezili-18 zokubeka iliso, akukho lungelelwaniso lwe-blade-induced blade kwitonela yomoya wetyuwa elunxwemeni, akukho lulawulo lokuqhutywa emva kwemijikelo ye-10,000 yokumisa.
I-Zibo Hongcheng Fan Co., Ltd. yakha aba balandeli kwindawo yabo engama-9,000 m² iZibo Blower Industrial Park-indawo enye apho yonke into yenziwa ngoomatshini, ilungelelanisiwe, idityanisiwe, kwaye ivavanyiwe. Akukho ndibano yokugqibela yekontraka. Akukho ziyekezo zomgangatho we-offshore. Wonke umlandeli uphethe ikhowudi ye-QR edibanisa kwingxelo yayo yokuvavanya: i-airflow curve, inqanaba loxinzelelo lwesandi kwi-1m, ukunyuka kweqondo lokushisa, kunye ne-vibration amplitude kwi-mm / s RMS.
Ukuba iprojekthi yakho yetonela elandelayo ifuna ukuhamba komoya onokuthi ukuthembe - hayi nje ukubala - qala nge I-SDF Sering Tunnel fan. Kuba kwiindawo ezivaliweyo, imizuzwana iyabala. Kwaye ukuthembeka ayisiyonto. Sisiseko.
