Hauv qhov nyuaj thiab puas tau - hloov chaw ntawm cov mines hauv av, xyuas kom raug cov dej ntws (dej, roj, emulsions, thiab lwm yam) tsis yog qhov tseem ceeb rau kev ua kom zoo tshaj plaws tab sis kuj ua kom muaj kev nyab xeeb thiab tiv thaiv kev puas tsuaj!
Niaj hnub no, peb yuav tshawb xyuas "kev nyab xeeb" ntawm cov dej hauv av hauv av- qhov kev nyab xeeb ntawm qhov siab siab -siab flowmeter rau kev tsuas.
Dab tsi yog "intrinsically nyab xeeb"?
"Intrinsically muaj kev nyab xeeb" yog hais txog kev nyab xeeb hauv lub cev thiab yog ib qho tseem ceeb tshaj plaws ntawm kev tawg- pov thawj rau cov khoom siv hluav taws xob hauv cov mines hauv av. Nws cov ntsiab lus tseem ceeb yog:
1. Kev txwv tsis pub muaj zog: Cov cuab yeej siv hluav taws xob tsim hluav taws xob nruj me ntsis txwv cov hluav taws xob hluav taws xob kom qis qis (txawm tias nyob rau hauv qhov teeb meem txhaum cai xws li luv luv Circuit Court thiab qhib circuits).
2. Spark Elimination: Txawm tias nyob rau hauv ib puag ncig uas muaj kev phom sij (xws li roj av thiab thee hmoov av), lub zog los ntawm sparks los yog thermal cuam tshuam tsim nyob rau hauv lub cuab yeej yog tsis txaus rau ignite ib tug tawg sib tov.
3. Kev Tiv Thaiv Dual: Feem ntau, nws yog siv ua ke nrog kev cuam tshuam kev nyab xeeb los tiv thaiv ntxiv kom muaj kev nyab xeeb ntawm lub zog nkag mus rau qhov chaw txaus ntshai.
Intrinsically muaj kev nyab xeeb flowmeters rau mining yog tsim thiab tsim los rau qhov kev nyab xeeb siab tshaj plaws no thiab yog tib txoj kev nyab xeeb rau kev saib xyuas kev khiav hauv qhov chaw tawg thiab tawg ntawm underground coal mines.
Daim Ntawv Pov Thawj Kev Nyab Xeeb Kev Nyab Xeeb Mining (MA Mark) yog koj qhov "dhau" rau cov mines hauv av:
Nws ua tau raws li qhov muaj kev nyab xeeb tawg hauv nruab nrab- cov ntaub ntawv pov thawj rau cov mines, xws li Ex ia I Ma lossis Ex ib I Ma. Qhov no tseem ceeb tshem tawm qhov kev pheej hmoo ntawm hluav taws xob tawg tawg los ntawm cov khoom siv saib xyuas kev khiav dej num, muab kev lav zoo rau kev nyab xeeb ntawm cov miners thiab mine chaw.
Lub flowmeter siv cov cuab yeej paub zoo tshaj plaws kom ua tiav qhov siab - qhov ntsuas qhov ntsuas dej ruaj khov thiab ruaj khov.
Nws saib xyuas cov tsis tseem ceeb xws li cov dej xa dej thiab cov dej ntws, qhov cua tshuab cua ntim, thiab hydraulic txhawb nqa emulsion txaus nyob rau lub sijhawm, muab cov ntaub ntawv txhim khu kev qha rau kev tsim khoom, kev tswj xyuas hluav taws xob, thiab kev tiv thaiv cov khoom siv.
Nws cov ntaub thaiv feem ntau ua tiav IP65 / IP67 lossis siab dua qhov ntsuas, ua kom tsis muaj plua plav thiab tsis muaj dej, thiab tiv taus cov dej hauv av, dej, thiab plua plav paug.
Cov khoom tseem ceeb yog tsim los ntawm corrosion-tiv taus thiab cuam tshuam- cov ntaub ntawv tiv taus, ua kom lub sijhawm ntev-, kev ua haujlwm ruaj khov nyob rau hauv ib puag ncig hauv av raug kev co, kev poob siab, cov av noo siab, thiab cov plua plav siab.
Qhov ntsuas ntsuas no tso tawm cov qauv teeb tsa (4-20mA, RS485 Modbus, thiab lwm yam) thiab tuaj yeem txuas nrog lub tshuab hluav taws xob mine automation (DCS / SCADA) lossis kev saib xyuas kev sib koom ua ke.
Nws tso cai rau kev saib xyuas tej thaj chaw deb, tiag tiag- lub tswb moos, cov ntaub ntawv keeb kwm, thiab kev tshuaj xyuas cov ntaub ntawv ntws, ua rau nws yog ib qho tseem ceeb rau kev nkag siab qhov tseem ceeb hauv kev tsim cov mines ntse thiab pob tshab.
Kuv qhov kev nyab xeeb intrinsically siab -pressure flowmeters yog siv dav hauv cov mines thiab yog qhov tseem ceeb "qhov muag thiab pob ntseg" kom ntseeg tau tias muaj kev nyab xeeb thiab ua haujlwm tau zoo ntawm ntau lub tshuab:
1. Mine Water Supply and Drainage System: Saib xyuas tus nqi ntws hauv chav dej twj tso kua mis loj, mining cheeb tsam chav dej twj tso kua mis, thiab lub ntsej muag ua haujlwm kom tsis txhob muaj dej nyab.
2. Kev Tiv Thaiv Hluav Taws Xob thiab Kev Tiv Thaiv Hluav Taws Xob: Saib xyuas cov kua dej / roj ntws hauv grouting, kev txhaj tshuaj nitrogen, thiab cov tshuaj tsuag plua plav pov tseg kom ua tau zoo ntawm kev tiv thaiv hluav taws thiab kev tiv thaiv.
3. Comprehensive Mining Workbench: Saib xyuas tus nqi ntws ntawm hydraulic txhawb nqa emulsion twj tso kua mis chaw nres tsheb kom paub tseeb tias kev txhawb nqa.
4. Compressed Air Self-Txoj Kev Tiv Thaiv: Saib xyuas tus nqi ntws hauv cov raj xa cua compressed kom ntseeg tau tias muaj huab cua txaus thaum muaj xwm txheej ceev.
Thaum xaiv ib qho kev nyab xeeb intrinsically siab -siab flowmeter rau mining, nws yog ib qho tseem ceeb kom nco ntsoov cov hauv qab no:
1. MA daim ntawv pov thawj yog tus chij liab: Ua haujlwm hauv av tsis muaj cov khoom siv mining siv tau daim ntawv pov thawj kev nyab xeeb yog txwv nruj!
2. Sib piv qhov tawg- pov thawj ntsuas: Paub meej tias cov khoom tawg- pov thawj (xws li Ex ia I Ma) ua tau raws li qhov yuav tsum tau muaj ntawm qhov chaw.
3. Kev xaiv tus qauv yog qhov tseem ceeb: Xaiv cov qauv ntsuas tsim nyog thiab cov qauv raws li qhov ntsuas nruab nrab (dej, roj, emulsion, thiab lwm yam), ntws ntau yam, cov yeeb nkab loj, siab thiab kub, qhov yuav tsum tau muaj, thiab cov teeb liab tawm.
4. Kev yuav khoom los ntawm cov kev raug cai: Xaiv ib tus neeg muag khoom muaj npe nrov nrog kev ua tiav tom qab - kev muag khoom thiab kev txhawb nqa.
Ib qho mining intrinsically muaj kev nyab xeeb siab -siab flowmeter yog ntau tshaj li qhov ntsuas ntsuas; nws ua hauj lwm raws li ib tug indispensable kev ruaj ntseg barrier thiab efficiency engine rau thee mine kev ruaj ntseg tshuab ntau lawm, thiab nws tus nqi deb tshaj nws tus nqi:
1. Ua kom muaj kev nyab xeeb ntawm lub neej: Tiv thaiv cov xwm txheej loj los ntawm cov khoom siv tsis ua haujlwm lossis tawg.
2. Zam tsis txhob poob ntau lawm: Kev soj ntsuam xyuas kom ruaj khov ua haujlwm thiab txo qis kev poob qis.
3. Txhim kho kev faib khoom kom zoo: Kev ntsuas qhov tseeb muab lub hauv paus rau kev txuag hluav taws xob, txo kev siv, thiab tswj tus nqi.
4. Txhim kho kev tswj hwm: Cov ntaub ntawv- tsav kev txiav txim siab- ua kom yooj yim rau kev hloov kho kuv qhov ntse.
ZHYQ tau koom nrog kev ua haujlwm ntawm kev saib xyuas kev nyab xeeb ntawm kuv tau ntau xyoo, muab ntau yam kev nyab xeeb ntawm cov ntsuas dej rau cov mines uas ua tau raws li cov qauv kev nyab xeeb tshaj plaws hauv tebchaws. Peb muab:
• Daim Ntawv Pov Thawj Kev Nyab Xeeb Kev Nyab Xeeb (MA)
• Ntau lub hauv paus ntsiab lus ntsuas kom ua tau raws li ntau yam kev xav tau
• Cov khoom zoo tshaj plaws thiab kev ntseeg siab
• Kev txhawb nqa kev tshaj lij thiab tom qab- kev muag khoom
Hu rau peb tam sim no kom ntseeg tau tias muaj kev nyab xeeb thiab ua haujlwm ntawm koj cov haujlwm mining!
