Coal mine plua plav tshem tawm cov tshuab kiv cua tsis yog qhov kev xaiv ntxiv-lawv yog qhov kev tiv thaiv pem hauv ntej tiv thaiv kab mob ua pa, kev pheej hmoo tawg, thiab kev tsim khoom poob qis. Hauv kev ua haujlwm hauv ntiaj teb tiag thoob plaws Shandong, Shanxi, thiab Inner Mongolia, peb tau pom qhov ua pa tsis ua haujlwm ua rau tsis muaj kev txwv tsis pub dhau 72 teev. Plua plav tsub zuj zuj ntawm lub cev muaj zog windings? Pom zoo nyob rau hauv peb qhov sib cais thee ntsej muag xa tawm xyoo tas los. Ntxuam tsis txaus tom qab rau lub hlis ntawm kev ua haujlwm tas mus li? Ib qho teeb meem rov tshwm sim-kom txog thaum cov neeg ua haujlwm hloov mus rau lub hom phiaj-ua, dynamically balanced units nrog kev sib xyaw plua plav-pob bearings.
Vim li cas Standard Kiv cua tsis nyob hauv av
Lub hom phiaj dav dav axial ntxuam txav cua. A Nqus Mine Plua Tswb Ntxuam txav huab cua * thaum tseem ciaj sia * abrasive particulate, high humidity, methane-laden atmospheres, thiab voltage fluctuations feem ntau nyob rau hauv tej thaj chaw deb daim phiaj mining. Feem ntau qhov ua tsis tiav rov qab mus rau peb qhov kev xav tsis sib xws:
- Kev xav #1: "Plua plav tsuas yog huab cua xwb." Kev muaj tiag: Coal plua plav nqa cov nqi zoo li qub, clings electrostatically rau impeller nto, thiab erodes txhuas hniav ntawm 0.08 hli / xyoo nyob rau hauv tas li load.
- Kev xav #2: "Explosion-proof = plua plav-tolerant." Kev muaj tiag: Ib qho Ex-d ntawv pov thawj lub cev muaj zog tiv thaiv hluav taws kub-tab sis tsis txwv cov plua plav los ntawm kev txhaws cov cua txias, nce cua kub los ntawm 22 ° C saum toj kawg nkaus txwv.
- Kev xav #3: "Kev siab dua CFM ib txwm txhais tau tias kev tswj hwm zoo dua." Kev muaj tiag: turbulent, unconditioned airflow recirculates hmoov av es tsis txhob ntes nws ntawm qhov chaw. Kev tshem tawm tau zoo xav kom nrawm nrawm sib phim rau hood tsim-tsis yog cov khoom siv raw.
Peb ntsuas qhov no ua ntej hauv 2023 retrofit ntawm Datong underground longwall vaj huam sib luag. Hloov 30 kW chav tsev sib xyaw ua ke nrog FBD series (dⅠ) counter-rotating axial kiv cua txiav cov pa plua plav tawm los ntawm 64% - tsis yog vim nws txav huab cua ntau dua, tab sis vim tias nws ob-theem siab nkhaus tswj> 18 m / s ntes nrawm ntawm lub tshuab nqus tsev nkag, txawm tias lim dej tsis kam nce.
Plaub Qhov Kev Tsim Kho Tsis Muaj Kev Sib Tham
Qhia meej a Nqus Mine Plua Tswb Ntxuam txhais tau hais tias qhov tseem ceeb tshaj plaws hauv kev ua pov thawj engineering tshaj catalog specs. Nov yog dab tsi tuav hauv underground:
- Dust-sealed dynamic balancing: Rotors sib npaug rau G2.5 qib * tom qab * tag nrho cov khoom sib dhos - suav nrog cov ntaub thaiv npog plua plav thiab cov ncej txuas - tsis yog cov impellers xwb. Tsis sib npaug vibration accelerates bearing coj los ntawm 3.7 × nyob rau hauv ib puag ncig plua plav.
- Corrosion-resistant structural framing: Galvanized steel vaj tse ua tsis tau qhov twg H₂S ntsib condensation. Titanium kiv cua tiv taus acid gas; coated carbon steel nrog ISO 12944 C5-M ntsuam xyuas kav 3 × ntev dua li cov xim xim hauv cov dej ntub dej.
- Explosion-proof integrity nyob rau hauv thermal stress: Lub cev muaj zog yuav tsum khaws cov ntawv pov thawj Ex-d ntawm 110 ° C ambient - feem ntau nyob ze ntawm cov tsav tsheb. Uas yuav tsum tau Class H rwb thaiv tsev * thiab * tsis-ferrous terminal thawv los tiv thaiv lub txim propagation los ntawm mounting bolts.
- Service-accessible maintenance: Tsis xav tau disassembly rau kev hloov cov kabmob. Cov kws tshaj lij hauv chaw nyob hauv Xuzhou tau lees paub tias lawv tau hloov ob-kab kheej kheej cov menyuam bearings ntawm 9-19 centrifugal blower hauv 47 feeb - tsuas yog siv ob lub wrenches thiab tsis muaj crane.
Cov ntaub ntawv xa tawm tiag: Dab tsi ua haujlwm nyob qhov twg
Tsis muaj kev daws teeb meem universal. Daim ntawv thov dictates architecture:
- Kev loj hlob kab lus: FBD series counter-rotating axial kiv cua xa 12-28 kPa zoo li qub siab - txaus los thawb cua los ntawm 500+ meters ntawm ducting thaum tuav lub ntsej muag tshaj tawm. Lawv qhov kev teeb tsa dual-lub cev muaj zog tshem tawm txoj hlua khi thiab tso cai rau kev pib ua haujlwm kom tsis txhob muaj kab sib txuas.
- Coal bunker & hloov cov ntsiab lus: Anti-corrosion centrifugal kiv cua nrog rov qab-kho hniav tuav 350-450 g / m³ plua plav loading yam tsis muaj kev poob qis. Peb tau sim ib chav nyob tsis tu ncua rau 14 lub hlis ntawm Yanzhou ntxuav cov nroj tsuag - kev ua haujlwm tau zoo nyob rau hauv ± 1.3% txawm tias muaj kev tu txhua hnub.
- Underground substations: Cov kiv cua tawg-pov thawj titanium khiav ntsiag to ntawm 72 dBA - txawm tias tag nrho cov load. Lawv cov kev tsim kho uas tsis yog sib nqus tshem tawm cov cua sov tam sim no nyob ze ntawm high-voltage switchgear.
Qhov teeb meem muaj zog. Kev siv tsis raug 45 kW kiv cua khiav 24/7 raug nqi $ 18,700 / xyoo hauv hluav taws xob ib leeg (ntawm $ 0.08 / kWh). Txoj cai Nqus Mine Plua Tswb Ntxuam- optimized rau lub cev tsis kam, tsis yog cov zis siab tshaj plaws - txiav los ntawm 22-31% yam tsis muaj kev cuam tshuam kev ntes.
Xaiv koj tus khub, tsis yog ib yam khoom xwb
Koj xav tau daim ntawv thov engineering-tsis yog PDF catalog. Thaum ib tus neeg siv khoom Heilongjiang tau tshaj tawm cov impeller tawg hauv lawv cov desulfurization ducts, peb pab neeg tau xa ib tus kws ua haujlwm hauv teb nrog lub vibrometer portable thiab particle counter. Hauv paus ua rau? Resonance ntawm 1,740 RPM coinciding nrog boiler pulsation zaus. Kev daws: Custom-tuned blade suav thiab txhawb nqa hub-xa hauv 11 hnub.
Zibo Hongcheng Fan Co., Ltd. tsim txhua txhua Nqus Mine Plua Tswb Ntxuam hauv tsev-los ntawm precision-machined titanium impellers rau tawg-pov thawj lub cev muaj zog windings-raws li ISO 9001-ua raws li kev soj ntsuam raws tu qauv. Txhua chav nyob rau hauv 48-teev kev kuaj load nrog simulated plua plav loading ua ntej xa zaub mov. Tsis muaj offshore subcontracting. Tsis muaj "standard" cuam tshuam.
Cov huab cua zoo hauv av tsis yog hais txog kev ua raws - nws yog hais txog kev txuas ntxiv. Nws yog qhov sib txawv ntawm qhov kev hloov pauv uas khiav huv si thiab ib qho nres los ntawm cov plua plav-ua rau methane tswb. Xaiv tus kiv cua uas tsim los rau kuv qhov kev muaj tiag-tsis yog phau ntawv cog lus.
