Imigodi engaphantsi komhlaba ifuna ukungena komoya okungaze kuphazamiseke-apho ukusilela kwefeni kungeyongxaki; kukwaphulwa kokhuseleko. Yiyo loo nto abasebenzi bemigodi e-Shanxi, e-Inner Mongolia, nakuMzantsi-mpuma we-Asia beqhubeka nokubuyela I-FBD fan fan yomgodi: hayi njengesivutheli segeneric, kodwa njengesivuthelo esingqiniweyo ebaleni, esingqina uqhushumbo-isitofu esichasene ne-axial flow flow yasekhaya yomoya eyenzelwe indawo ezisingqongileyo zero-margin.
Sikubonile okwenzekayo xa imilinganiselo yokungenisa umoya ikhutshelwa kwiincwadana ezinemifanekiso-engaqinisekiswanga phantsi komhlaba. Umxhasi omnye kumthungo wamalahle one-8.2% yoxinaniso lwemethane ufakelwe i-axial fan engaqinisekisiweyo elinganiswe "ukusetyenziswa kwemigodi." Iphumelele iimvavanyo zasefektri. Yasilela ngoSuku lwe-17-i-vibration spiked, iibheringi zigqithise kakhulu, kwaye indlu yemoto yaqhekeka phantsi kwebhayisekile eshushu. Oyena nobangela? Akukho lungqamaniso oluguqukayo kwitorque egcweleyo. Akukho vavanyo lokungeniswa kothuli olufanisiweyo. Akukho siqinisekiso ngokuchasene nemigangatho ye-GB 3836.1–2021 yobungqina bokudubula. Uluhlu lwe-FBD luphepha loo migibe ngokuyila-kungekhona ngohlengahlengiso.
Kutheni i-Counter-Rotation Ingeyiyo nje iJargon yokuthengisa
Uninzi lwabalandeli be-axial bajikeleza i-rotor enye. Uchungechunge lwe-FBD lusebenzisa iirotor ezimbini ezizimeleyo ezijikelezayo ezijikelezayo. Oku akusiyo i-theory esebenzayo-imveliso enokulinganiswa: ukuya kuthi ga kwi-15% yoxinzelelo oluphezulu lwe-static kwi-draw yamandla afanayo, i-8-12 dB (A) ingxolo ephantsi kwiimitha ezi-3, kunye ne-zero axial thrust kwiibheringi. Silinganise oku kwi-situ ngexesha lovavanyo lweentsuku ze-90 kwi-1,200-m-deep iron ore shaft e-Anhui. Ngoxinzelelo lwe-inlet static oluguquguqukayo phakathi kwe-120 Pa kunye ne-210 Pa ngenxa yokumelana nokutshintsha kwetonela, ukuseta i-rotor kabini igcine ukuhamba komoya ngaphakathi kwe-± 2.3% ye-setpoint-ngelixa iiyunithi ezikhuphisanayo ze-rotor enye zikhukulisiwe ± 9.7%.
Olo uzinzo luvela kungqamaniso lomatshini-hayi ulungiso lwesoftware. I-rotor nganye ikhwela kwindibano yayo ephezulu echanekileyo, ehambelana ne-≤0.03 mm yokufundwa kwesalathisi esipheleleyo (TIR). Akukho zibhokisi zegiya. Akukho ukutyibilika ibhanti. Idityaniswe nje ngokuthe ngqo, intlanganiso yeenjini zokuthintela uqhushumbo Ex dⅠ Mb yezatifikethi zoDidi M1.
Ukuqina Kwehlabathi Lokwenyani: Yintoni Esinda Ngaphantsi Komhlaba
Umhlwa ubulala abalandeli ngokukhawuleza kunothuli. Kwimigodi yamalahle etyebile ngesalfure, izindlu zentsimbi ezingacocwanga zigqwesa ngaphantsi kweenyanga ezili-18. Uchungechunge lwe-FBD lusebenzisa iifreyimu ezishushu zediphu kunye ne-epoxy-polyester yomgubo we-polyester okhethiweyo obekwe kwi-ISO 12944 C4. Kodwa i-coating yodwa ayinqumli-siqinisa imimandla yoxinzelelo olubalulekileyo: ii-hubs ze-impeller zifumana i-3-mm-thick steel stainless liners; iicones zokungena zifakela iipleyiti zokunxiba zeAR400 ezinokuthathelwa indawo; kwaye zonke iziqhoboshi ziyi-A4-80 engenanto kunye ne-anti-seize compound efakwe ngaphambili.
Sikwavavanya ngaphaya komgangatho. Iyunithi nganye ifumana uvavanyo lwe-4-yure oluqhubekayo lwe-salt-spray kwi-35 ° C, ilandelwa ziiyure ezingama-72 kwi-95% ye-RH yomswakama kwi-40 ° C-emva koko ukuvavanya ukusebenza kwangoko. Ukuba ukuhamba komoya kwehla ngaphezu kwe-1.5%, kuyanqatshwa. Akukho ngaphandle. Olo qeqesho luchaza ukuba kutheni iiyunithi ze-FBD zihlala zingena kwiiyure ezingama-42,000+ zokusebenza ngaphambi kwenkonzo yokuqala enkulu-phantse kabini i-median yeshishini kumjikelo ofanayo womsebenzi.
Ukufakela kunye nokuHlanganyela: Apho uninzi lwabathengisi bayeka kafutshane
"Plag-and-play" ayikho phantsi komhlaba. Udinga ukuhambelana kwe-ducting, ukuguquguquka kombane, kunye nokujongwa kwexesha lokwenyani-hayi nje uphawu lweCE. Uthotho lwe-FBD ngeenqanawa ezineengenelo ezintathu eziphambili zokudityaniswa:
- Iinketho zojongano lombhobho: Umgangatho we-600 mm, 700 mm, kunye ne-800 mm flanges-kunye neeadaptha ze-tapered zesiko kwi-24 "okanye i-30" yeenkqubo ze-duct
- Ukuguquguquka kwamandla: I-Dual-voltage windings (380 V / 660 V) enokuzikhethela i-1140 V ulungelelwaniso lofakelo oluhamba ixesha elide.
- I-Smart-ready Architecture: Ezakhelwe ngaphakathi PT100 abenzi boluvo kuzo zombini iimotor windings + vibration transducers (4–20 mA output), pre-wireed to terminal blocks-akukho splicing field required
Akukho zixhobo zokubuyisela. Akukho kulibaziseka "qhakamshelana neqela lethu lobunjineli". Ezi azizongezo-zidibene nefektri, zivavanywe, kwaye zibhalwe kwingxelo yokugunyazisa ihanjiswe kunye neyunithi nganye.
Ukwenza Ukhetho Olufanelekileyo—Ngaphandle Kokuqikelela
Ukukhetha i I-FBD fan fan yomgodi Ayikokuthelekisa amandla ehashe nobude betonela. Imalunga nokwenza imephu yemeko yakho eyona meko imbi kakhulu: amanqanaba aphezulu emethane, kulindeleke ukulayishwa kothuli (mg/m³), ubushushu obuthileyo, kunye nexesha lokuphumla elivumelekileyo lokugcinwa. Yiyo loo nto singacaphuli kwiikhathalogu. Siqala ngesicwangciso sakho somgodi, isicwangciso sokungenisa umoya, kunye nokufundwa kwerhasi yembali-kunye nemodeli yokusebenza kusetyenziswa iijika zefeni eziqinisekisiweyo zeCFD, hayi iitshathi ezilindelekileyo.
Ukuba ubushushu bomoya owuthathayo bubetha rhoqo kwi-45°C, ufuna ukugqunyelelwa kwemoto (iKlasi H, hayi F). Ukuba i-fan yakho iqhuba iiyure ezingama-22 / imini kunye nemijikelo yemizuzu emi-3 yokumisa/yokuqala, udinga i-stator windings eyomeleziweyo kunye nokuhambelana kokuqala. Ezi “ayizozinto zikhethwayo”-azinakuxoxisana. Kwaye zibhakwa kuyo yonke iyunithi ye-FBD ngaphambi kokuba ishiye umgangatho wemveliso weZibo Blower Industrial Park.
Ukuthembeka phantsi komhlaba akufezeki ngokungasebenzi. Yakhelwe kwi-rotor, ifakwe kwizindlu, iqinisekiswe kwiseli yokuvavanya, kwaye ibonakaliswe apho ibaluleke kakhulu-ebumnyameni, phantsi koxinzelelo, kunye nobomi obuxhomekeke ekuhambeni komoya. Lowo ngumgangatho we-FBD series. Hayi ekujoliswe kuko. Hayi isithembiso. Isiseko.
