Kev tawg-pov thawj qhov ntxuam tshuab ua kom huab cua txav mus rau qhov chaw uas lub txim tuaj yeem txhais tau tias muaj kev puas tsuaj loj. Hauv cov mines thee, cov tshuaj ua cov tunnels, lossis cov chaw pabcuam roj av, qhov cua tsis yog hais txog kev nplij siab - nws yog hais txog kev ciaj sia. Peb tau pom cov kiv cua tsis ua haujlwm nyob rau hauv kev ntxhov siab thermal, misfire thaum lub sij hawm methane spikes, los yog corrode tom qab rau lub hlis nyob rau hauv sulfur-laden airflow. Tias yog vim li cas cov engineers qhia txog qhov tawg-pov thawj qhov kiv cua tsis yog qhov kev xaiv - tab sis raws li qhov yuav tsum tau ua hauv paus.
Vim li cas Standard Tunnel Kiv cua tsis ua haujlwm hauv thaj chaw muaj kev phom sij
Qhov chaw muaj kev nyab xeeb qhov cua xav tau ntau dua li qhov ntim ntawm cov pa. Nws xav tau kev nyab xeeb hauv nruab nrab-tsis muaj qhov hluav taws kub, tsis muaj qhov kub thiab txias, tsis muaj txoj hauv kev tawm zoo li qub. Tus qauv axial lossis centrifugal tunnel kiv cua siv induction motors nrog cov terminals raug, cov tsev tsis muaj qhov cua, thiab cov txhuam cov pa roj carbon monoxide. Hauv Cheeb Tsam 1 (qhov twg cov pa hluav taws xob tawg zoo li yuav tshwm sim) lossis Cheeb Tsam 2 (qhov twg lawv nyob ib ntus), cov yam ntxwv no ua txhaum IEC 60079-0 thiab GB 3836.1 cov qauv ncaj qha.
Peb tau sim peb cov kiv cua tawm ntawm qhov chaw nyob hauv simulated mine huab cua (5.5% CH₄, 22 ° C, 95% RH). Txhua qhov kub ntawm qhov chaw txwv tsis pub dhau 47 feeb. Muaj ob lub thermal cutouts; ib tug ignited ib qho kev sim roj sib tov thaum pib surge. Lub hauv paus ua rau? Tsis muaj ntawv pov thawj lub cev muaj zog windings, ungrounded impeller hubs, thiab yas fasteners tsim electrostatic nqi. Kev ua tsis tiav tiag tiag hauv ntiaj teb tsis yog qhov theoretical - nws tau sau tseg hauv Tuam Tshoj Lub Xeev Kev Tswj Xyuas Kev Nyab Xeeb Kev Nyab Xeeb cov ntaub ntawv los ntawm 2022-2023.
Dab tsi Ua Qhov Tseeb Explosion-Proof Tunnel Ntxuam?
Ib daim ntawv pov thawj tawg-pov thawj ntxuam integrates plaub txheej uas tsis yog-negotiable: lub cev muaj zog enclosure (dⅠ los yog Ex d IIB T4), flameproof sib koom tsim (tsis yog "txhim taws-resistant" xwb), kub-chav kawm-muab cov ntaub ntawv, thiab dynamic tshuav validated ntawm 110% ntsuas ceev. FBD series (dⅠ) counter-rotating axial flow kiv cua-tsim tshwj xeeb rau underground thee mine headings-siv dual explosion-proof motors nyob hauv cam khwb cia txhuas enclosures nrog 0.012 hli siab tshaj qhov sib koom ua ke. Nws cov impellers khiav ntawm 1,480 rpm tab sis nyob qis dua 135 ° C saum npoo kub txawm tias ntawm 105% load. Qhov ntawd tsis yog kev lag luam luam-uas yog ntsuas cov ntaub ntawv los ntawm peb lub chaw kuaj xyuas ISO 17025-kev lees paub.
Tab sis daim ntawv pov thawj ib leeg tsis txaus. Peb tau saib cov neeg siv khoom teeb tsa cov kiv cua uas tau lees paub tsuas yog pom cov huab cua tawg vim qhov tsis sib haum ntawm cov kav dej tsis sib haum lossis qhov hluav taws xob poob hla 800-meter cable khiav. Ib qho kev daws teeb meem tiag tiag yuav tsum suav rau qhov sib txawv ntawm cov kab ke: cov kab hluav taws xob zoo li qub, qhov hluav taws xob tsis sib haum, cov av noo nyob ib puag ncig ntawm lub cev muaj zog tiv thaiv, thiab kev sib haum xeeb ntawm kev sib txawv ntawm cov tsav tsheb. Tias yog vim li cas txhua chav FBD nkoj nrog qhov chaw tshwj xeeb kev ua tau zoo nkhaus - tsis yog ib daim ntawv teev npe - thiab suav nrog lub thawv davhlau ya nyob twg grounding lugs loj rau 35 mm² tooj liab hlau.
Customization tsis yog khoom kim heev-Nws yog qhov tsim nyog ua haujlwm
Ib-loj-haum-tag nrho tsis muaj nyob hauv av. Lub kiv cua qhov rau lub 3.2 m txoj kab uas hla thee drift xav tau sib txawv thrust, suab nrov profile, thiab mounting geometry tshaj ib tug rau ib tug 5.8 m tshuaj nroj tsuag nkag ncej. Peb tau tsim ntau dua 174 qhov kev cai sib txawv hauv 27 lub hlis dhau los - suav nrog cov qauv titanium-bladed rau H₂S-nplua nuj flue gas ducts, dual-inlet configurations rau parallel ventilation circuits, thiab low-frequency-modulated versions uas txo resonant vibration nyob rau hauv bolted pob zeb phab ntsa.
Qhov tseem ceeb customization levers peb niaj hnub siv:
- Lub cev muaj zog winding chav kawm: H-chav rwb thaiv tsev txheej txheem, hloov mus rau C-chav kawm rau> 200 ° C ambient daim ntaub ntawv
- Cov khoom siv impeller: Aluminium alloy (tus qauv), stainless hlau 316 (chloride ib puag ncig), los yog Qib 7 titanium (H₂S + siab tshaj tawm)
- Tswj interface: RS-485 Modbus RTU ua ntej-wired, 4-20 mA analog tawm tswv yim, lossis hardwired thaum muaj xwm ceev nres kev koom ua ke
- Daim ntawv pov thawj Scope: Dual-certified rau GB 3836 thiab ATEX 2014/34/EU-tsim los ntawm CNEX thiab SGS
Tsis muaj kev nplua rau lub sijhawm ua haujlwm. Peb cov kab ntau lawm muaj 12 core motor thav duab, 8 impeller casting qauv, thiab 5 vaj tsev variants - tag nrho cov kev sim ua ntej thiab sau tseg. Kev cai specs xauv hauv ua ntej machining pib, tsis yog tom qab sib dhos.
Kev ua tau zoo tiag tiag pib ua ntej kev teeb tsa
Kev xa khoom tsis tiav. Peb tau taug qab cov teeb meem tom qab kev teeb tsa thoob plaws 41 qhov chaw: 62% taug qab mus rau hauv av tsis raug, 23% rau cov khoom siv tsis zoo, thiab 15% rau kev nkag mus rau qhov cuam tshuam los ntawm kev tsim cov kav dej tsis zoo. Tias yog vim li cas txhua qhov kev txiav txim suav nrog kev them nyiaj pub dawb engineering - tsis yog phau ntawv PDF xwb. Peb pab neeg tshuaj xyuas koj qhov chaw hla ntu, qhov xav tau roj muaj pes tsawg leeg, lub zog qhov chaw ruaj khov, thiab kev tswj xyuas kev txwv. Peb ua qauv airflow decay hla 200+ meters ntawm ductwork thiab chij voltage poob kev pheej hmoo ua ntej koj txiav pob zeb.
Zibo Hongcheng Ntxuam Co., Ltd. tsim cov chav nyob hauv nws 9,000 m² Zibo Blower Industrial Park qhov chaw - qhov twg txhua tus kiv cua tau dhau 72 teev ntawm kev ntsuas kev thauj khoom tas mus li ntawm qhov ntsuas siab, ua raws li kev ntsuas ntsuas kub thiab ntsuas qhov tso tawm ib nrab. Koj tau txais daim ntawv xeem kos npe, tsis yog daim ntawv pov thawj daim ntawv nplaum. Vim hais tias thaum methane concentration hits 4.3%, dab tsi tseem ceeb yog tsis ua raws li cov ntaub ntawv-nws yog seb tus kiv cua tseem tig.
Rau cov kws tshaj lij hais txog kev tawg-pov thawj qhov kiv cua tshuab, cov lus nug tsis yog "Lub hom phiaj twg?" Nws yog "Tus khub twg nkag siab tias qhov cua tsis ua haujlwm tsis yog lub sijhawm poob - nws yog qhov txaus ntshai." Qhov kev nkag siab ntawd nyob hauv qhov kev ua siab ntev ntawm weld seam, lub cev muaj zog winding dielectric lub zog, thiab tus kws tshaj lij lub peev xwm los txheeb xyuas cov av txuas ntxiv ntawm qhov chaw. Qhov ntawd yog qhov kev nyab xeeb tiag tiag pib - thiab qhov twg nws yuav tsum tsis txhob xaus.
