Hlau mine lub tshuab ua pa tsis yog cov cuab yeej siv xwb - lawv yog thawj kab ntawm kev tiv thaiv kev ua tsis taus pa, tawg, thiab kub ntxhov. Hauv kev ua haujlwm hauv ntiaj teb tiag tiag, peb tau pom qhov ua pa tsis ua haujlwm ua rau muaj kev khiav tawm thaum muaj xwm txheej ceev - tsis yog vim cov kiv cua tawg, tab sis vim tias lawv tsis paub meej txog methane tsub zuj zuj, plua plav loading, lossis kev sib txawv ntawm lub siab ceev. Ib qho xwm txheej xyoo 2023 hauv Shandong nonferrous mine tau lees paub tias nws: tus kiv cua axial thawj tau ntsib airflow ntim lub hom phiaj ntawm daim ntawv tab sis tsis tuaj yeem tuav lub siab zoo li qub siab tshaj 1,800 Pa thaum lim tsis kam nce 40% tom qab 72 teev ntawm kev ua haujlwm tas mus li. Qhov ntawd yog thaum kev ntseeg tau nres ua theoretical.
Vim li cas "Tsuas Airflow" yog qhov kev xav txaus ntshai
Underground hlau mines xav tau ntau tshaj li cov zis volumetric. Lawv xav tau cov lus teb tsis muaj zog, kev ua haujlwm ruaj khov nyob rau hauv kev vibration, thiab tus cwj pwm tsis zoo hauv cov huab cua tawg. FBD series (dⅠ) explosion-proof pressure-injection counter-rotating axial flow local ventilator-siv nyob rau hauv ntau dua 37 hard-pob zeb mines thoob plaws Tuam Tshoj thiab cov teb chaws Asia-tau tsim tshwj xeeb los kaw qhov sib txawv. Nws dual-lub cev muaj zog, counter-rotating tsim muab 22-28% siab zog efficiency tshaj ib-theem axial units ntawm tib lub zog input. Qhov tseem ceeb tshaj, nws cov chav kawm I, Division 1 tawg-pov thawj ntawv pov thawj tsis yog bolted rau-nws tau ua rau hauv lub cev muaj zog geometry, ncej sealing interface, thiab spark-resistant impeller casting txheej txheem.
Tab sis kev ua tau zoo tsis yog hais txog specs xwb. Nws yog hais txog dab tsi tshwm sim thaum ambient kub hits 52 ° C, txheeb ze av noo nce siab tshaj 95%, thiab silica plua plav concentration ntau tshaj 8 mg / m³. Standard kiv cua bearings txeeb. Belt drives plam. Lub cev muaj zog windings degrade. Tias yog vim li cas hlau kuv lub tshuab ua pa xaiv yuav tsum pib nrog ib puag ncig daim ntawv qhia - tsis yog kev tshawb nrhiav catalog. Peb tau pom cov neeg siv khoom txiav lub sijhawm ua haujlwm los ntawm 60% thaum lawv qhia cov ntaub ntawv qhia txog roj av borehole thiab cov sijhawm thauj khoom txhua hnub ua ntej ua tiav kev xaiv kiv cua. Cov ntaub ntawv tiag tiag yeej qhov kev xav tsis zoo txhua lub sijhawm.
Peb Tsis-Tshaj Tawm hauv Hlau Mine Ventilation Design
- Kev tawg-pov thawj kev ncaj ncees yuav tsum txuas mus dhau lub cev muaj zog. Cov kiv cua ntsuas rau Zone 1 ib puag ncig tseem ua tsis tiav yog tias cov khoom siv hluav taws xob tsis muaj kev txuas ntxiv hauv av lossis yog cov silencers muaj cov hlua khi uas tsis muaj kev tiv thaiv. FBD series integrates certified grounding straps ncaj qha mus rau mounting flange - tsis muaj teb retrofitting yuav tsum tau.
- Kev tuav plua plav tsis yog xaiv tau - nws yog cumulative. Tus kiv cua xa 12,000 m³ / h thaum pib poob mus rau 9,300 m³ / h tom qab 14 hnub yam tsis muaj kev saib xyuas yog tias qhov nkag nkag tsis txaus. Titanium cov kiv cua-tsim kom muaj corrosion-resistant, siab-abrasion zones-tswj> 94% ntawm cov ntsuas cua ntawm 30-hnub tsis tu ncua.
- Tswj kev teb tseem ceeb hauv av. Qhov sib txawv zaus tsav (VFDs) yuav tsum tshwm sim hauv 1.2 vib nas this rau CO sensor ua rau. Cov chav nyob nrog analog-tsuas tswj loops ntxiv 4-7 vib nas this ntawm latency-lub sij hawm txaus rau methane concentration hla 5% LEL qhov pib hauv qhov chaw nres.
Thaum Tawm-hauv-Tsev Tsis Muaj Kev Nyab Xeeb txaus
Qee tus yuav sib cav tias cov kiv cua txheem ua haujlwm zoo nrog cov khoom siv ntxiv kev nyab xeeb. Txawm li cas los xij, ntxiv cov ntaub ntawv pov thawj tawg rau sab nraud rau lub hom phiaj axial kiv cua tsim thermal bottlenecks, txo cov kev pab cuam, thiab voids thawj cov ntaub ntawv pov thawj. Qhov phem tshaj, nws qhia txog cov ntsiab lus tsis ua haujlwm tshiab: gasket compression poob, conduit foob degradation, thiab kev co-induced thaiv kev qaug zog. Customization tsis yog hais txog khoom kim heev - nws yog hais txog kev tshem tawm cov kev cuam tshuam uas muaj kev pheej hmoo siab.
Zibo Hongcheng Ntxuam Co., Ltd. tsim lub hauv paus ntsiab lus no rau hauv nws txoj haujlwm. Thaum lub mine tooj liab hauv Yunnan xav tau lub kiv cua muaj peev xwm ntawm 3,200 Pa static siab ntawm 8,500 m³ / h thaum ua haujlwm tsis tu ncua ntawm 75 ° C qhov kub thiab txias, engineers tsis hloov cov qauv uas twb muaj lawm. Lawv rov ua cov hniav twist profile hauv ANSYS CFX, xaiv Inconel 625 rau rotor hubs, thiab siv tau cov thermal expansion kam rau ua thoob plaws 120-teev kev ntsuas kub. Qhov tshwm sim? Ib chav tsev tau ntawv pov thawj rau GB 3836.1-2021 thiab ISO 8573-1 Chav Kawm 2 rau kev kis kab mob sib kis - xa hauv 11 lub lis piam, tsis yog rau lub hlis.
Dab tsi los tom qab Invoice tseem ceeb tshaj plaws
Lub tshuab ua pa hlau tsis tau txais nws tus nqi thaum lub sijhawm teeb tsa - nws ua pov thawj nws tus kheej thaum lub sijhawm ua haujlwm thib peb ntawm lub lim tiam 17. Qhov ntawd yog thaum kev co kev sib haum xeeb nthuav tawm misalignment, thaum bearing kub tiam sis nthuav tawm lubrication inconsistencies, thiab thaum tswj logic exposes firmware kab. Zibo Hongcheng Ntxuam Co., Ltd. suav nrog cov chaw taws teeb kuaj mob hauv txhua FBD thiab titanium-series units: Modbus TCP kev txhawb nqa, onboard kub / siab / vibration sensors, thiab firmware-upgradeable logic controllers. Cov kws tshaj lij hauv teb tsis txhob tos txog kev tawg-lawv pom qhov sib txawv ntawm 3% amplitude nce, tsis yog 30%.
Kev pabcuam tsis ua haujlwm. Nws yog kwv yees. Lawv daim ntawv thov engineering pab neeg tshuaj xyuas mine qhov cua schematics ua ntej xa khoom - tsis yog rau upsell, tab sis rau tus chij duct ntev tsis sib haum, lub luj tshib vim muaj kev kub ntxhov, lossis kev kho qhov siab ntawm qhov siab uas hloov cov kev xav tau ntawm lub zog nce mus txog 11%. Qhov kev saib xyuas no txwv tsis pub cov nqi xa rov qab thiab ua kom cov dav hlau ua raws li Tuam Tshoj tus AQ 2013-2018 cov qauv kev nyab xeeb.
Kev nyab xeeb-tseem ceeb qhov cua tsis muaj chaw rau kev cuam tshuam. Txhua lub tshuab ua pa hlau yuav tsum teb peb nqe lus nug ua ntej xa mus: Nws puas muaj sia nyob ib puag ncig? Nws puas teb rau cov teeb liab hem sai dua li tib neeg cov tshuaj tiv thaiv lub sijhawm? Puas yog nws txoj kev txhawb nqa ecosystem cia siab tias yuav tsis ua haujlwm - tsis yog sau lawv? Zibo Hongcheng Ntxuam Co., Ltd. teb yog - tsis yog raws li kev thov kev lag luam, tab sis raws li cov ntaub ntawv xeem, cov ntawv teev lus teb, thiab cov ntaub ntawv txheeb xyuas thib peb. Vim underground, airflow tsis ntsuas hauv cubic meters ib feeb. Nws tau ntsuas hauv lub neej txhawb nqa, hloov ua tiav, thiab zam kev kub ntxhov.
