I. Kev Xaiv Kev Tshawb Fawb: Ua kom ntsuas kev ntseeg tau los ntawm qhov chaw
Qhov tseeb pib nrog kev xaiv raug; Nws yog ib qho tseem ceeb los xyuas kom meej qhov siab ntawm qhov sib txuam ntawm lub sensor thiab qhov kev siv scenario.
1. Matching Explosion-Qhov pov thawj
Intrinsically muaj kev nyab xeeb sensors nrog cov mining khoom kev nyab xeeb cim (MA) thiab tawg- pov thawj daim ntawv pov thawj yuav tsum tau siv nyob rau hauv cov thee mines. Explosion-cov cim pov thawj xws li "Ex ib I" yuav tsum pom meej meej.
2. Kev kho kom haum rau cov khoom kuaj pom thiab ib puag ncig
Tsis txhob siv catalytic combustion sensors nyob rau hauv ib puag ncig uas muaj silicon los yog sulfur compounds los tiv thaiv "poisoning" tsis ua hauj lwm.
Rau cov av noo siab lossis corrosive gas ib puag ncig, cov khoom siv nrog stainless hlau vaj tse thiab kev tiv thaiv IP68 yuav tsum raug xaiv los txhim kho kev sib khi.
3. Tso cai rau Range Margin
Xaiv cov sensors uas muaj qhov tsawg kawg yog 20% siab dua qhov kev ua haujlwm tiag tiag kom tsis txhob ntev - lub sijhawm dhau los ua rau muaj kev hloov pauv hauv cov qauv elastomer lossis vuam tawg.
II. Txhim kho Environmental Adaptability: Txo cov kev cuam tshuam sab nraud
Cov kev ua haujlwm nyuaj yog qhov ua rau muaj kev cuam tshuam thiab tsis ua haujlwm; Cov phiaj xwm tiv thaiv yog tsim nyog.
1. Temperature Control: High temperatures accelerate component aging and cause coating materials to melt. In high-temperature environments (>60 degree), cov ntaub thaiv npog cua sov lossis dej / cua txias yuav tsum tau nruab.
2. Moisture thiab Dust Protection: Moisture thiab plua plav tuaj yeem ua rau luv luv. Sensors nrog welded seals los yog nqus tsev vacuum- cov khoom siv nitrogen puv yuav tsum raug xaiv, vim tias lawv cov sealing kev ua tau zoo tshaj cov roj hmab gaskets lossis cov nplaum nplaum.
3. Electromagnetic Interference Resistance: Muaj zog electromagnetic teb tuaj yeem ua rau cov teeb liab tawm turbulence. shielded cables yuav tsum tau siv thiab txhim khu kev qha hauv av; cov ntxaij lim dej yuav tsum tau nruab yog tsim nyog.
4. Kev tiv thaiv corrosion: nyob rau hauv acidic, alkaline, los yog ntsev tsuag ib puag ncig, sensors nrog hmoov-coated finishes los yog 304 stainless hlau vaj tse yuav tsum tau xaiv, thiab nto corrosion yuav tsum tau xyuas tsis tu ncua.
III. Standardized Calibration thiab Verification: Ua kom cov ntaub ntawv tsis tu ncua
Tsis tu ncua calibration yog lub hauv paus ntsiab lus ntawm kev tswj qhov tseeb thiab yuav tsum tau muab coj los ua ke nrog ib tug dynamic triggering mechanism.
1. Teem Calibration Cycles los ntawm Hom
Methane Sensor (Catalytic): Txhua hli
Carbon Monoxide Sensor: Peb Hlis
Kub/Pressure Sensor: Semi-ib xyoos
Ceev/Position Sensor: Txhua xyoo
(Raws li kev ua haujlwm tshwj xeeb, lub voj voog yuav tsum luv los ntawm 30% -50%)
2. Cov txheej txheem calibration txheem
Ua ntej calibration, paub meej tias ib puag ncig ua raws (kub 15-25 degree, tsis muaj kev cuam tshuam zoo). Siv cov pa roj carbon monoxide lossis cov teeb liab uas tuaj yeem ua tiav kom tiav xoom-point, qhov tseeb, thiab lub tswb ntsuas ntsuas ntsuas, thiab sau cov tsis muaj cim xeeb.
3. Tshaj tawm -Calibration Verification yog yuav tsum tau
Paub meej tias qhov kev ua tau zoo ntawm lub sensor ua tau raws li cov qauv los ntawm kev ruaj khov- kev sim hauv xeev, kev txheeb xyuas rov ua dua, ntsuas lub sij hawm teb, thiab ntsuas lub tswb ua haujlwm.
IV. Kev Tswj Xyuas Txheej Txheem: Txhim kho lub sijhawm ntev - Lub Sijhawm Tiv Thaiv Lub Sijhawm
Muab cov sensors tso rau hauv kev tswj hwm kev nyab xeeb tag nrho txhawm rau txhim kho kev ntseeg tau.
1. Siv nrog Kev Tiv Thaiv Kev Nyab Xeeb
Intrinsically muaj kev nyab xeeb systems yuav tsum tau siv nrog kev ruaj ntseg teeb meem los txwv lub voj zog thiab tiv thaiv overvoltage thiab overcurrent puas tsuaj rau lub sensor.
2. Teeb tsa cov cuab yeej ceeb toom ntxov
Teeb tsa cov ntaub ntawv ceeb toom txawv txav (xws li drift tshaj qhov txwv, teb qeeb) hauv kev saib xyuas kom ua tiav kev cuam tshuam ntxov.
3. Tsim Cov Ntaub Ntawv Kho Mob: Sau lub sijhawm ntawm txhua qhov kev tu, ntsuas, thiab hloov kho kom yooj yim rau kev taug qab cov kev hloov pauv hloov pauv thiab ua kom muaj kev hloov pauv.
4. Kev cob qhia cov neeg ua haujlwm thiab cov txheej txheem ua haujlwm: Cov neeg ua haujlwm yuav tsum paub cov kev txiav txim siab yooj yim thiab qhia tam sim thiab daws cov kev nyeem ntawv txawv txav lossis lub tswb ua haujlwm tsis zoo.
