Thaum DK45 ncej ntws kiv cua thiab hlau mine lub tshuab ua pa siv los ua cov kiv cua tseem ceeb thiab cov kiv cua chaw nres tsheb, lawv yuav tsum tau nruab nrog cov diffusers siab. Cov kiv cua loj saum npoo nruab nrog lub diffuser tuaj yeem hloov ib feem ntawm lub zog dynamic rau hauv siab zoo li qub, txo qhov tsis muaj zog ntawm qhov hluav taws xob, thiab ua tiav lub hom phiaj ntawm kev txuag hluav taws xob. Cov kiv cua tau nruab rau hauv av, thaum nruab nrog lub diffuser, tuaj yeem tsis tsuas yog txo cov coefficient hauv zos, tab sis kuj txo cov nqi siab ntawm lub qhov hluav taws xob diffuser, yog li txo qis hauv zos ntawm cov kiv cua thiab txuag hluav taws xob siv hluav taws xob.
DK45 Mine Axial Flow Ntxuam: Core Structure thiab Principple of Metal Mine Ventilation Ntxuam
1. Counter-rotating dual-theem tsim: Ob lub cev muaj zog ntawm tib lub zog yog txuas ncaj qha mus rau ob lub txee-rotating impellers, tshem tawm qhov xav tau ntev shafts lossis siv tsav; C-4 / Ⅱ hom peb-dimensional ntws twisted tis hniav yog siv, nrog cov ces kaum adjustable; ib lub nplhaib stabilizing yog tsim rau hauv cov pa duct kom tiv thaiv surging, thiab tus yam ntxwv nkhaus tsis muaj hump.
2. Rov qab cua ntws: Tsis tas yuav tsum muaj cua rov qab duct; tsuas yog thim rov qab cov kev taw qhia ntawm kev sib hloov tuaj yeem ua tiav qhov rov qab huab cua ntws ua haujlwm ntawm ntau dua 60%.
3. Cov ntaub ntawv: Lub plhaub yog ua los ntawm Q235 steel phaj vuam, thiab cov hniav yog hollow steel daim hlau nrog alloy hniav shafts, uas yog resistant rau underground blasting shock tsis, noo noo-pov thawj thiab corrosion-resistant.
Qauv thiab cov ntsiab lus tseem ceeb
• Feem ntau muab faib ua ob series: DK40-6 (6-ncej lub cev muaj zog, ceev 980r/min) thiab DK40-8 (8-ncej lub cev muaj zog, ceev 730r/min); tus qauv naj npawb ntawm 15 # mus rau 26 #. •

Kev ua tau zoo ntawm DK45 ncej kiv cua rau hlau mines:
1. Kev ua haujlwm siab thiab txuag hluav taws xob: Tri-dimensional txaus tsim + tsav ncaj qha, kev ua haujlwm siab, thiab kev txuag hluav taws xob ntev ntev.
2. ruaj khov thiab nyab xeeb: Anti-surge steady flow nplhaib, tsis muaj kev pheej hmoo ntawm kev tawg; resistant rau tej yam, haum rau complex underground ib puag ncig.
3. Saj zawg zog thiab adjustable: adjustable hniav lub kaum sab xis kom tau raws li cov huab cua ntim / cua siab yuav tsum tau ntawm lub mine ntawm txawv lub sij hawm.
4. Kev txhim kho yooj yim thiab kev saib xyuas: Cov qauv tsim, tus nqi qis hauv kev tsim kho; kev tsim tsav ncaj qha txo qis kev sib kis thiab kev saib xyuas.
DK45 ncej ntxuam, hlau mine qhov cua ntxuam daim ntawv thov scenarios
• Cov kiv cua tseem ceeb hauv av thiab cov kiv cua hauv av rau cov hlau thiab cov mines tsis yog hlau; core kiv cua rau ntau theem chaw nres tsheb qhov cua tshuab; qhov cua rau qhov tunnels thiab pej xeem huab cua tiv thaiv tej yaam num.
