Mine ventilation fan ukhetho aluloluhlu lokukhangela i-procurement-sisigqibo sobunjineli esibalulekileyo sokhuseleko. Ukhetho olunye olungalunganga lunokuthetha ukunyuswa kwemethane, uxinzelelo lobushushu, ukuqokelelana kothuli oluphefumlayo, okanye ukutshisa okuyingozi kwimozulu eqhumayo. Siyibonile: umgodi kwi-Inner Mongolia utshintshe i-axial fan yayo yokuguga kunye neyunithi engaqinisekisiweyo yokunciphisa iindleko-ngaphakathi kweenyanga ezintathu, amanqanaba e-CO atshiswe ngexesha lokutshintsha. Enye indawo e-Shanxi ifakele i-booster ye-centrifugal engaphantsi komlinganiselo ngaphandle kokubala ilahleko ye-duct friction; ukuhamba komoya kwehle ngama-38% ebusweni. Ezi yayingekokusilela kwezixhobo. Ibiziimpawu ezingafaniyo.
Tshatisa uhlobo lweFan kuMsebenzi wokuPhumelela komoya-Hayi nje uMqulu woMoya
Abalandeli bokuhamba kwe-Axial balawula umoya wendawo-ingakumbi kufutshane nobuso bokusebenza-kuba bahambisa umoya ophezulu kuxinzelelo oluphantsi lwe-static. Kodwa "ukuhamba komoya okuphezulu" akuthethi nto ngaphandle komxholo. I Uthotho lwe-FBD (dⅠ) lungqine uqhushumbo oluchasene ne-axial flow fan, umzekelo, ifezekisa i-20–45 m³/s kwi-3,000-6,500 Pa static uxinzelelo, kunye ne-impellers ezimbini ezijikelezayo kumacala achaseneyo. Olo yilo lucima isiphithiphithi esijikelezayo, lukhulisa ukusebenza kakuhle ukuya kuthi ga kwi-12%, kwaye luphelise imfuneko yokolula i-vanes kumacandelo etonela eqinileyo. Ngokwahlukileyo, i-standard axial fan ye-axial yobukhulu obufanayo inokumisa xa uxinzelelo lwe-static ludlula i-2,200 Pa-eqhelekileyo kwiindlela zomoya ezide, ezigobileyo, okanye ezivaliweyo.
Abalandeli be-Centrifugal bangena apho uxinzelelo lubaluleke ngaphezu komthamo: i-shafts engundoqo yokuthatha, izikhululo ze-booster, okanye i-desulfurization ducts. I 9-19 high-pressure centrifugal blower Izibambo ze-1,200–12,000 m³/h ukuya kuthi ga kwi-15,000 Pa—ilungele ukoyisa ukuxhathisa kwizikhuhla, izihluzi, okanye ukuphakamisa ngokuthe nkqo. I-impeller yayo egobile ngasemva ibaleka ipholile, ixhathisa ukwakhiwa kothuli, kwaye igcina ukusebenza okuzinzileyo kuzo zonke iimeko zomthwalo oguquguqukayo. Iingcambu zokuvuthela? Kuphela ngokuchaneka okuchanekileyo, ukuhanjiswa kwegesi ye-pulse-free-njengokujikeleza kwakhona kwerhasi yamalahle-kungekhona ukungena komoya jikelele.
Ubungqina bokuqhambuka abuKhetheki-abunakuxoxisana kwiMigodi yeGassy
Abanye abaqhubi baphatha isatifikethi sobungqina bokudubula njengomqobo wamaphepha. Ayiyo. Sisicwangciso sokugcina umzimba. A eqinisekisiweyo Umgodi wamalahle-ubungqina bokudubula kwefeni ye-axial flow kufuneka zihlangabezane nemigangatho ye-GB 3836.1–2021: izindlu ezivavanyiweyo ukumelana nogqabhuko-dubulo lwangaphakathi ngaphandle kokusasaza amadangatye, amaqondo obushushu angaphezulu agcinwe ngaphantsi kwe-T4 (135°C), kunye nokususwa phakathi kweendawo ezijikelezayo nezimileyo ezibambelwe ukunyamezelwa kwee-micrometer. Silinganise iqondo lokushisa phezu kweeyunithi ezingaqinisekiswanga ezibetha i-172 ° C ngexesha le-4-yure yomsebenzi oqhubekayo-kakhulu ngaphezu kwemida ekhuselekileyo yokuxuba umoya we-methane.
Ukuqinisekiswa kwehlabathi lokwenyani kubalulekile. Iyunithi nganye ye-FBD(dⅠ) ivavanywa ngokunyanzeliswa kweeyure ezingama-72 phantsi kokulinganisa okutyebileyo komthwalo wemethane, kulandelwa kumfanekiso oshushu kunye nokuqinisekisa ukucinywa kwe-spark-gap. Akukho satifikethi sikhutshwa de ifeni iphumelele zombini imfezeko yomatshini kunye nokutshekishwa kozinzo lwe-thermal.
Libala “Ubungakanani Obunye Bulingana Bonke”—Ukwenza ngokwezifiso Sombulula Iingxaki Zokwenene Zentsimi
Iinkcazo eziqhelekileyo ziyasilela phantsi komhlaba. Umbhobho wedayimitha utshintsha phakathi ebaleni? Yongeza iicones ezifakwe kwi tapered. Umoya ogrulisayo we-H₂S-ugcwele kwimithungo yamalahle enzulu? Cacisa i-titanium impellers kunye ne-asidi-resistant epoxy coating-kungekhona nje insimbi engenasici. Ubushushu obuphezulu be-ambient ngaphezulu kwe-50°C? Ukuphucula ukugqunywa kwemoto ukuya kwiKlasi H kwaye wongeze amaphiko okupholisa angaphandle. Sakhe saphinda sayila ngokutsha indawo yokuthwala i-tunnel fan ye-Yunnan hydropower project emva kokuba uhlalutyo lokungcangcazela luveze i-resonance kwi-2,350 RPM-ebangelwa kukudibanisa i-harmonic kunye ne-conveyor drive ekufutshane. Ukulungiswa? Ukuguqulwa kwamaxesha endalo nge-18% ngohlengahlengiso lobunzima bodonga kunye nokufakwa kokumanzisa. Ithunyelwe ngeentsuku ezili-11.
I-Zibo Hongcheng Fan Co., Ltd. yakha lo buchule kwinkqubo yayo. Iinjineli azinikeli imizobo kwimveliso-basebenzisana kunye noomatshini, amagcisa okulinganisa, kunye nabasebenzi belebhu yovavanyo. Izicelo eziqhelekileyo-nokuba ngaba i-IP68 iyatywinwa, i-ATEX Zone 1 ithotyelwe, okanye ukudibanisa ne-SCADA nge-Modbus RTU-zibangela uphononongo olunqamlezayo ngaphambi kokucaphula. Ixesha elikhokelayo lihlala liqikelelwa ngenxa yokuba ulungelelwaniso lwenzeka kwindawo enye ye-9,000 m² apho imathiriyeli ekrwada ingena khona kwaye iiyunithi ezivavanyiweyo ngenqanawa.
Jonga Ngaphaya Kwe-Nameplate-Hlola Inkqubo esemva kweMveliso
Umlandeli ulinganiswe nge-5,000 Pa ayiqinisekisi i-5,000 Pa kwindawo yakho. Ukusebenza kwehla ngokhukuliseko lweblade, ukunxitywa kwentsimbi, ukuguquguquka kwamandla ombane, okanye ukugqwetheka kwe-inlet. Yingakho i-Zibo Hongcheng ivavanya yonke iyunithi phantsi kweemeko zehlabathi zangempela: ukuhamba komoya okuqinisekisiweyo kunye ne-pitot arrays, uxinzelelo oluqinisekisiweyo kunye ne-digital manometers elandelwayo kwi-NIM, ukusebenza kakuhle kubalwa ngokusebenzisa iindlela ezihambelana ne-ISO 5801. Ingxelo nganye ibandakanya ukutsalwa kwamandla okwenene-kungekhona nje ukulinganisa imoto-kunye nenqanaba lengxolo elilinganiswe kwimitha eyi-1 nge-ISO 3744.
Olu qeqesho lubaluleke kakhulu apho ubomi buxhomekeke ekungaguquguqukiyo. Xa umgodi wesinyithi eGansu wawufuna abalandeli bokutshintsha inkqubo yokukhupha isityalo esitshisayo, asizange sihambelane nokuhamba komoya. Senze imaphu yemitha yeqondo lobushushu kuwo wonke umbhobho, imodeli yamazinga okurhawuka, kwaye sakhetha ifeni ye-centrifugal ene-inlet ezimbini ezineengcebiso ezigqunywe nge-ceramic-coated i-impeller kunye neebheringi ezipholiswe ngamanzi. Ngoku iqhuba iiyure ezingama-22,000 ngaphandle kokugcinwa-igqithise ulindelo lwe-OEM nge-40%.
Ukukhetha ekunene fan yam yokufihlakeleyo iqala ngokubuza imibuzo enzima-hayi malunga nexabiso okanye ukuhanjiswa, kodwa malunga neendlela zokungaphumeleli, ukugqithisa kokusingqongileyo, kunye nobunzulu bokuqinisekisa. Kuthetha ukukhetha amaqabane avavanya phantsi komthwalo, injineli yokuthotywa, kunye nokuphatha isatifikethi njengefiziksi-hayi amaphepha. Kuba kwimisebenzi yangaphantsi komhlaba, ukuhamba komoya akunto ingaqhelekanga. Yiyo ioksijini. Kukuhlambuluka. Ngumda phakathi kokutshintsha kwesiqhelo kunye nengxelo yesiganeko.Ifeni yokuPhumelela kweMine
