Explosion-pov thawj Tsau Scissor Lift

Taw qhia rau Kev tawg-Cov pov thawj ntsuas ntawm Tsau Lifts
Cov cuab yeej siv hluav taws xob ruaj khov siv nyob rau hauv qhov chaw muaj kev phom sij (cov pa hluav taws xob, vapors, combustible plua plav) yuav tsum ua raws li kev tawg - cov qauv kev tiv thaiv kom tsis txhob muaj hluav taws xob hluav taws xob, qhov chaw kub kub, lossis hluav taws xob zoo li qub. Qhov "explosion-cov pov thawj ntsuas" txhais tau tias lub tshuab nqa tuaj yeem ntsia tau qhov twg thiab yuav tsum muaj kev tiv thaiv dab tsi rau nws cov tshuab hluav taws xob thiab hydraulic.
1) Cov Txheej Txheem Txheej Txheem Txheej Txheem Zoo
Kev tawg - pov thawj kev ntsuam xyuas yog nyob ntawm seb thaj chaw muaj kev phom sij raug txhais li cas.
A. North America (NEC / CEC – Class/Division System)
Class I: Flammable gases lossis vapors
Chav Kawm II: Combustible plua plav
Chav Kawm III: Fibers lossis ya
Kev faib:
Division 1 – Muaj xwm txheej tam sim no nyob rau hauv ib txwm ua haujlwm
Phaj 2 – Muaj xwm txheej tshwm sim tsuas yog nyob rau hauv cov xwm txheej txawv txav
Piv txwv cim:
Chav Kawm I, Division 1, Pawg D, T4
Qhov twg:
Pawg D=Propane, roj av vapors
T4=Max nto temp Tsawg dua lossis sib npaug li 135 degree
B. International / Europe (IECEx / ATEX - Zone System)
Zone 0 / 1 / 2 – Gas huab cua
Zone 20/21/22 – Plua plav huab cua
Piv txwv cim:
Ex d IIB T4 Gb
Qhov twg:
Ex=Kev tiv thaiv tawg
d=Flameproof enclosure
IIB=Gas group
T4=Chav ntsuas kub
Gb=Cov cuab yeej tiv thaiv qib
2) Yuav ua li cas thiaj ua tau ib qho Scissor Lift Explosion-Cov pov thawj?
Lub nqa txiab ruaj ruaj tsis yog qhov tshwm sim tawg - pov thawj. Nws yuav tsum tau tshwj xeeb configured.
Kev hloov pauv tseem ceeb:
1. Explosion-Proof Motor
Certified enclosure (Ex d lossis Class I Div 1)
Spark- tsis muaj kev tsim kho sab hauv
Tswj qhov kub thiab txias
2. Flameproof Hluav taws xob tswj txee
Heavy cam khwb cia aluminium lossis steel enclosure
Nplaim txoj kev sib txuas
Certified cable caj pas
3. Intrinsically Safe Circuits (Ex kuv)
Tsawg- hluav taws xob tswj kev xaim
Barrier isolators
Tiv thaiv ignition txawm nyob rau hauv qhov teeb meem txhaum cai
4. Anti-Kev kho mob zoo li qub
Grounding ntawm cov qauv
Static tso zis tswj
Conductive hydraulic hoses
5. Kev tswj qhov kub thiab txias
Roj ntsuas kub ntsuas
Tsawg lub cev muaj zog qhov kub thiab txias (T1-T6 ntsuas)
