Explosion -pov thawj Limit Switches: Cov Neeg Saib Xyuas Kev Nyab Xeeb hauv Ib puag ncig txaus ntshai

Hauv kev lag luam xws li petrochemicals, mining, thiab kev ua zaub mov, hluav taws xob sparks los yog kub kub generated thaum lub sij hawm ua hauj lwm ntawm machinery yuav ua rau ib tug saw ntawm cov pa phem los yog plua plav, ua rau muaj kev puas tsuaj loj. Kev tawg- pov thawj txwv hloov pauv, raws li qhov tseem ceeb ntawm kev tswj hwm kev nyab xeeb, tshwj xeeb yog tsim los ua kom tau raws li kev saib xyuas txoj haujlwm thiab cov teeb liab tawm tswv yim hauv qhov chaw muaj kev phom sij, dhau los ua "tsis pom kab ntawm kev tiv thaiv" kom muaj kev nyab xeeb ntawm kev lag luam.

Classification thiab Application of Explosion-proof Gas Environment
Raws li cov txheej txheem thoob ntiaj teb, cov huab cua ntawm cov pa roj tawg tau muab faib ua zones 0 (nruam muaj nyob), 1 (muaj peev xwm muaj) thiab 2 (lub sijhawm luv luv - lub sijhawm nyob). Explosion-pov thawj limiter keyboards yog tsim rau ntau theem ntawm kev phom sij los ntawm kev tawg sib txawv-cov ntaub ntawv pov thawj:

1. Flameproof hom (Ex d): Lub plhaub muaj zog yog siv los tiv thaiv kev tawg hauv siab thiab tiv thaiv cov nplaim hluav taws. Piv txwv li, Honeywell BX series txwv cov keyboards muaj cov nplaim hluav taws xob tsim los ua kom cov pa cua txias hauv qab qhov kub thiab txias, ua rau lawv tsim nyog rau kev tiv thaiv valve hauv cov nroj tsuag petrochemical.
2. Ntxiv hom kev nyab xeeb (Ex e): Tshem tawm qhov phom sij los ntawm kev tsim hluav taws xob zoo. Lub Zhejiang Aoxiang ASK-510N txwv kev hloov pauv tau txais lub davhlau ya nyob twg kaw thiab tiv thaiv corrosion, ua haujlwm tsis tu ncua nyob rau hauv -40℃rau +100℃ib puag ncig, thiab tau dav siv rau kev saib xyuas txoj haujlwm valve hauv cov raj xa dej ntawm refinery.
3. Essence Security (Ex ia): txwv lub zog hluav taws xob mus rau qhov chaw nyab xeeb. Lub German- ua Ex 12 KU-5m txwv kev hloov pauv siv ib zaug - rhuav tshem cov neeg sib txuas thiab txuas txuas ua ntej kom ua tiav qhov tsis muaj kev pheej hmoo kis tau tus mob rau kev soj ntsuam roj hauv cov roj av mine.

Tej yam kev thov Scenarios

• Roj rov qab: Nyob rau ntawm ntug dej hiav txwv drilling platforms, tawg- pov thawj kev txwv cov keyboards saib xyuas qhov nce thiab poob txwv ntawm kev xyaum los tiv thaiv cov khoom siv overtravel los ntawm kev ua kom tawg.
• Kev tsim tshuaj lom neeg: Hauv reactor agitator txoj haujlwm nrhiav kom pom, txwv kev hloov pauv tau txuas nrog tus actuator los ntawm NAMUR tus qauv interface, muab qhov tseeb - lub sijhawm tawm tswv yim ntawm cov txheej txheem tsis.
• Kev thauj mus los ntawm cov roj av: Cov kav dej valve qhib thiab kaw cov txheej txheem saib xyuas cov txheej txheem yog tsim los nrog ob lub voj PLC cuam tshuam los xyuas kom muaj kev ntseeg siab ntawm kev sib kis ntawm 99.99% ntawm cov teeb liab ntawm -35℃rau +70 degree.

1.Dust Explosion-Proof Classification
Plua plav ib puag ncig tau muab faib ua zones 20 (nruam muaj), 21 (tej zaum) thiab 22 (lub sijhawm luv-) nyob ntawm seb muaj kev phom sij. Explosion- pov thawj txwv hloov pauv yog tiv thaiv los ntawm kev xaiv cov qauv sib khi thiab cov khoom siv:
Kev Tiv Thaiv Kev Tiv Thaiv: IP67 rated foob tsim los tiv thaiv 7J ntawm lub zog poob siab. Yueqing Renmin Instrument cov khoom lag luam siv dual - lub kaw lus kaw lus (lub tes tsho sab nraud + Teflon sealing nplhaib) uas tuav qhov ntsuas IP66 tiv thaiv txawm tias ntawm -60℃.
Kev xaiv cov khoom: tawv aluminium plhaub, polyester txheej, tsis tsuas yog ua tau raws li qhov yuav tsum tau tawg, tab sis kuj corrosion kuj. Honeywell VPX series cov khoom lag luam tau lees paub los ntawm NEMA, ua tiav 10 xyoo sib law liag ntawm cov plua plav- dawb ib puag ncig kev saib xyuas rau cov nroj tsuag ua qoob loo.
2.Tej daim ntawv thov Scenarios
Grain Storage: Nyob rau hauv silo rooj vag txoj hauj lwm nrhiav kom tau, qhov kev txwv hloov tsav lub cam mechanism ib coaxial connector nrog ib tug tiv tauj quab yuam ntawm 10A / 220VAC los xyuas kom meej qhov kev nyab xeeb pib thiab nres ntawm loj conveying khoom.
Kev ua ntoo: Hauv cov kab ntau lawm particleboard, tawg - pov thawj limiter hloov saib xyuas cov kev txwv mus los ntawm cov cuab yeej sawing, siv SPDT kev sib cuag configurations rau bidirectional motion tswj, nrog ib tug neeg kho tshuab lub neej ntawm ntau tshaj 1 lab laps.
Kev lag luam kws tshuaj: huv chamber tshuaj tiv thaiv lub nkoj lub hau txoj hauj lwm tawm tswv yim system txais yuav qhov tseem ceeb kev ruaj ntseg tsim, raws li SIL2

Daim ntawv pov thawj kev nyab xeeb, ua tau raws li GMP cov cai.

1.Extreme Environment Adaptability

• Qhov kub thiab txias: -60℃rau +100 degree, ua tau raws li kev khiav hauj lwm huab cua hauv Siberian roj teb thiab refineries hauv Middle East.
• Kev Tiv Thaiv Kev Tiv Thaiv: 316L stainless hlau ua haujlwm lub taub hau thiab npib tsib xee-plated cov neeg nyob twj ywm xeb- pub dawb rau 5 xyoo nyob rau hauv cov ntsev tsuag ib puag ncig ntawm marine platform.
• Mechanical zog: Los ntawm IK10 kev ntsuam xyuas qhov cuam tshuam (20J cuam tshuam lub zog), mine hoists txwv kev hloov tuaj yeem tiv taus qhov cuam tshuam pob zeb, tsis muaj qhov txhaum.

2.Kev txawj ntse txawj hloov tshiab

• Kev xa xov wireless: tawg- pov thawj txwv- txoj haujlwm hloov pauv nrog LoRa modules tso cai rau kev saib xyuas tej thaj chaw deb thiab txo cov nqi xaim hauv thaj chaw muaj kev phom sij.
• Tus kheej-Diagnostics: Ua-nyob rau hauv microprocessors ntes kev tiv tauj hnav thiab tsim kua muag thiab muab kev ceeb toom ntxov ntawm kev saib xyuas; Piv txwv li, qhov taw qhia qhov muag pom hauv ASK series cov khoom lag luam tuaj yeem ua rau pom qhov pom ntawm -tawm txheej xwm.
• Modular tsim: Honeywell BX series txhawb nqa ntsaws-thiab- ua si hloov pauv hloov, txo lub sijhawm txij li 2 teev mus rau 15 feeb kom txo qis kev poob qis.

Ntsiab Parameter Matching

• Blast- ntawv pov thawj: yuav tsum muaj cov ntaub ntawv tiav xws li Ex d IIC T6 Gb, qhia txog cov roj siv tau (IIA-IIC) thiab qeb kub (T1-T6).
• Kev tiv thaiv kev ntsuas: IP67 yog qhov yuav tsum tau muaj thiab cov khoom pov thawj IP68 yuav tsum tau ua haujlwm hauv qab dej.
• Kev sib cuag muaj peev xwm: Xaiv 6A / 24VDC lossis 10A / 220VAC specifications raws li kev thauj khoom kom tsis txhob muaj kev pheej hmoo ntawm kev sib cuag vuam.

International Certification Systems

• ATEX Certification: qhov tseem ceeb rau EU kev lag luam nkag, suav nrog qib kev tiv thaiv cov cuab yeej (Gb / Gc) thiab kev ua haujlwm ib puag ncig (gas / plua plav).
• IECEx Certification: International Electrotechnical Commission tus qauv, lees paub ntawm 152 lub teb chaws cov tswv cuab.
• CCC daim ntawv pov thawj: Tuam Tshoj cov khoom lag luam yuav tsum tau ntawv pov thawj, raws li GB 3836 series ntawm lub teb chaws tus qauv.

Los ntawm North Hiav Txwv cov roj av mus rau Sahara Suab puam, los ntawm cov mines hauv av mus rau siab - qhov siab qhov siab drilling rigs, tawg- pov thawj kev txwv hloov pauv ua thawj kab ntawm kev tiv thaiv kev nyab xeeb kev lag luam nrog kev tshawb pom qhov tseeb ntawm 0.01 hli thiab lub neej txhua hnub ntawm ntau lab xyoo. Raws li IoT thev naus laus zis sib koom ua ke nrog kev tsim kev ruaj ntseg tseem ceeb, Cov Neeg Saib Xyuas Tsis Txaus Siab tab tom hloov los ntawm cov yam ntxwv yooj yim mus rau kev soj ntsuam kev ruaj ntseg ntse, muab kev lees paub zoo rau kev lag luam thoob ntiaj teb kev hloov pauv 4.0. Xaiv qhov tawg- pov thawj kev hloov pauv uas ua tau raws li cov qauv thoob ntiaj teb tsis yog tsuas yog kev nqis peev hauv kev nyab xeeb ntawm cov cuab yeej, tab sis kuj tseem hwm tus nqi ntawm lub neej.
