Mine ventilation fan kev xaiv tsis yog ib daim ntawv teev kev yuav khoom-nws yog kev txiav txim siab txog kev nyab xeeb-tseem ceeb engineering. Ib qho kev xaiv tsis ncaj ncees tuaj yeem txhais tau tias muaj cov tshuaj methane siab, kev ntxhov siab thaum tshav kub kub, cov plua plav ua pa, lossis txawm tias muaj kev puas tsuaj loj hauv cov huab cua tawg. Peb tau pom nws: ib lub mine hauv Inner Mongolia hloov nws cov kiv cua axial laus nrog lub tsev tsis muaj ntawv pov thawj los txiav cov nqi-hauv peb lub hlis, CO qib nce siab thaum hloov pauv. Lwm qhov chaw hauv Shanxi tau teeb tsa lub centrifugal booster undersized yam tsis suav txog kev sib txhuam ntawm cov kav dej; airflow poob 38% ntawm lub ntsej muag. Cov no tsis yog cov khoom siv tsis ua haujlwm. Lawv tau specification tsis sib haum.
Match Ntxuam Hom rau Qhov Cuab Yeej Lub Luag Haujlwm - Tsis yog Cua Volume xwb
Axial flow kiv cua tswj hwm qhov cua hauv zos-tshwj xeeb yog nyob ze ntawm lub ntsej muag ua haujlwm-vim tias lawv xa cov cua ntws siab ntawm qhov tsis zoo li qub. Tab sis "siab airflow" txhais tau tias tsis muaj dab tsi tsis muaj ntsiab lus. Cov FBD series (dⅠ) explosion-proof counter-rotating axial flow fanPiv txwv li, ua tiav 20-45 m³ / s ntawm 3,000-6,500 Pa zoo li qub siab, nrog ob lub impellers tig rov qab cov lus qhia. Qhov kev tsim no tshem tawm kev sib hloov turbulence, boosts efficiency txog li 12%, thiab tshem tawm qhov xav tau rau straightening vanes nyob rau hauv nruj tunnel seem. Hauv qhov sib piv, tus qauv ib-theem axial kiv cua ntawm qhov loj me tuaj yeem nres thaum lub siab zoo li qub tshaj 2,200 Pa-feem ntau nyob rau hauv ntev, khoov, lossis ib feem ntawm cov hlab cua.
Cov kiv cua centrifugal nkag mus rau qhov chaw siab tshaj qhov ntim: cov khoom siv loj, cov chaw nres tsheb, lossis cov kav dej desulfurization. Cov 9-19 high-pressure centrifugal blower tuav 1,200–12,000 m³ / h ntawm mus txog 15,000 Pa - zoo tagnrho rau kev kov yeej kev tawm tsam los ntawm cov tshuaj txhuam, lim, lossis ntsug nqa. Nws rov qab-kho impeller khiav txias dua, tiv thaiv plua plav buildup, thiab tswj kev ua haujlwm ruaj khov nyob rau hauv cov xwm txheej sib txawv. Roots blowers? Tsuas yog rau qhov tseeb, tsis muaj cov pa hloov pauv hloov pauv-zoo li cov pa roj recirculation-tsis yog qhov cua dav dav.
Kev tawg-pov thawj tsis yog xaiv tau-Nws tsis tuaj yeem sib tham hauv Gassy Mines
Qee tus neeg ua haujlwm kho cov ntaub ntawv pov thawj tawg ua cov ntaub ntawv nyuaj. Tsis yog. Nws yog lub tswv yim tiv thaiv lub cev. Ib daim ntawv pov thawj thee mine tawg-pov thawj axial flow kiv cua yuav tsum ua tau raws li GB 3836.1-2021 cov qauv: vaj tsev kuaj kom tiv thaiv kev tawg hauv qhov tsis muaj nplaim hluav taws, qhov kub ntawm qhov chaw khaws cia qis dua T4 (135 ° C), thiab tshem tawm ntawm kev sib hloov thiab qhov chaw nyob ruaj ruaj rau micrometer kam rau ua. Peb tau ntsuas qhov kub ntawm qhov ntsuas kub ntawm 172 ° C thaum lub sijhawm ua haujlwm tas li 4-teev-zoo tshaj qhov txwv kev nyab xeeb rau methane-cua sib tov.
Kev pov thawj tiag tiag hauv ntiaj teb tseem ceeb. Txhua chav FBD (dⅠ) yuav tsum tau ua 72-teev kub hnyiab-hauv kev simulated methane-nplua nuj load, ua raws li thermal imaging thiab spark-gap clearance validation. Tsis muaj daim ntawv pov thawj muab kom txog thaum lub kiv cua dhau ob qho tib si kev ntseeg siab thiab thermal stability check.
Tsis nco qab "Ib Qhov Loj Fits Tag Nrho" - Kev Kho Kom Zoo Kho Cov Teeb Meem Hauv Teb
Standard specs tsis underground. Txoj kab uas hla ntawm cov kav dej hloov nruab nrab khiav? Ntxiv tapered inlet cones. Corrosive H₂S-laden huab cua nyob rau hauv tob coal seams? Qhia meej titanium impellers thiab acid-resistant epoxy txheej - tsis yog stainless hlau xwb. Kub ambient kub tshaj 50 ° C? Txhim kho lub cev muaj zog rwb thaiv tsev rau Chav H thiab ntxiv cov cua txias sab nraud. Peb ib zaug redesigned ib tug kiv cua qhov bearing vaj tse rau ib tug Yunnan hydropower project tom qab kev vibration tsom xam qhia resonance ntawm 2,350 RPM - tshwm sim los ntawm harmonic coupling nrog cov nyob ib sab conveyor tsav. Qhov kho? Hloov lub ntuj zaus los ntawm 18% ntawm phab ntsa thickness hloov thiab damping inserts. Xa hauv 11 hnub.
Zibo Hongcheng Ntxuam Co., Ltd. tsim qhov agility no rau hauv nws cov txheej txheem. Cov kws tsim khoom tsis tso cov duab kos rau kev tsim khoom - lawv koom tes nrog cov kws tsim khoom, cov kws tshaj lij, thiab cov neeg ua haujlwm kuaj. Kev thov kev cai - txawm tias IP68 sealing, ATEX Zone 1 ua raws, lossis kev koom ua ke nrog SCADA ntawm Modbus RTU - ua rau muaj kev tshuaj xyuas ntau dua ua ntej hais. Lub sijhawm txhuas nyob twj ywm kwv yees vim tias kev hloov kho tau tshwm sim hauv tib lub 9,000 m² qhov chaw uas cov khoom siv raw nkag mus thiab kuaj cov nkoj.
Saib dhau ntawm daim ntawv teev npe-Saib cov txheej txheem tom qab cov khoom
Tus kiv cua ntsuas rau 5,000 Pa tsis lav 5,000 Pa ntawm koj qhov chaw. Kev ua tau zoo degrades nrog cov hniav yaig, kev coj tus kheej, kev hloov hluav taws xob, lossis inlet distortion. Tias yog vim li cas Zibo Hongcheng kuaj txhua chav nyob hauv lub ntiaj teb tiag tiag: airflow txheeb xyuas nrog calibrated pitot arrays, siab validated nrog cov manometers traceable rau NIM, efficiency xam siv ISO 5801-raws txoj kev. Txhua daim ntawv tshaj tawm suav nrog kev kos lub zog tiag tiag - tsis yog kev ntsuas lub cev muaj zog - thiab lub suab nrov ntsuas ntawm 1 meter ib ISO 3744.
Qhov kev qhuab qhia no tseem ceeb tshaj plaws uas lub neej nyob ntawm qhov sib xws. Thaum lub mine metallurgical nyob rau hauv Gansu xav tau kev hloov kiv cua rau nws cov sintering cog tso pa system, peb tsis tsuas yog phim airflow. Peb tau teeb tsa qhov kub thiab txias gradients thoob plaws lub ductwork, ua qauv piv txwv ntawm kev puas tsuaj, thiab xaiv ib lub kiv cua dual-inlet centrifugal nrog cov lus qhia ceramic-coated impeller thiab dej txias bearings. Tam sim no nws tau khiav 22,000 teev yam tsis muaj kev saib xyuas - dhau qhov kev cia siab OEM los ntawm 40%.Mine Ventilation Ntxuam
Xaiv txoj cai Kua cua ntxuam pib nrog nug cov lus nug nyuaj - tsis yog hais txog tus nqi lossis kev xa khoom, tab sis hais txog hom kev ua tsis tiav, ib puag ncig huab cua, thiab qhov tseeb qhov tob. Nws txhais tau tias xaiv cov neeg koom tes uas ntsuas hauv qab load, engineer rau degradation, thiab kho cov ntawv pov thawj raws li lub cev - tsis yog cov ntaub ntawv. Vim tias hauv kev ua haujlwm hauv av, airflow tsis paub meej. Nws yog oxygen. Nws yog dilution. Nws yog qhov nruab nrab ntawm kev hloov pauv niaj hnub thiab qhov xwm txheej qhia.Mine Ventilation Ntxuam
