Shenhai Explosion-Proof
Cov “Ex” thaum pib ntawm qhov ua tiav tawg-pov thawj cim qhia tias nws yog ib hom khoom tawg-pov thawj, tseem tsis tau piav qhia txog nws qhov tshwj xeeb tawg-pov thawj nta.
Cov cim ntawm cov khoom tawg-pov thawj hluav taws xob
| Hom | Hom tawg pov thawj | Ntau hom kev nyab xeeb | Intrinsic Safety Hom | Hom Siab Zoo | Roj puv hom | Xuab zeb puv Pwm | Spark Dawb Hom | Exm | Hom Airtight |
|---|---|---|---|---|---|---|---|---|---|
| Kos npe | d | e | ia i ib | p | o | q | n | m | h |
Cov cim no qhia txog hom kev tawg-pov thawj, qib, thiab qeb. Piv txwv li:
Ex d ii hais txog Chav Kawm II, Qib B, Pab pawg T3 flameproof hluav taws xob ntaus ntawv;
Ex ia II AT5 qhia txog chav II, Qib A, Pab pawg T5 yog qib intrinsically muaj kev nyab xeeb hluav taws xob ntaus ntawv;
Ex ep II BT4 tsim ib qho kev nyab xeeb ntau dua cov khoom siv hluav taws xob nrog cov khoom siv hluav taws xob rau kev tiv thaiv tawg;
Exd II (NH3) los yog Ex d II ammonia qhia a flameproof khoom siv hluav taws xob tsim los rau helium gas ib puag ncig;
Ex d I sawv cev rau cov mining-specialized Class I flameproof hluav taws xob ntaus ntawv;
Ex d/II BT4 txhais tau hais tias cov khoom siv hluav taws xob tsis muaj hluav taws xob siv tau rau ob chav I thiab Chav Kawm II, Qib B, Pawg T4.
Plua plav tawg-pov thawj cov khoom siv hluav taws xob muaj cim nrog DIP (Plua plav Ignition pov thawj) cim. Piv txwv suav nrog:
DIP A20 thiab DIP A21, rau Hom A plua plav tawg-pov thawj cov cuab yeej hauv Zones 20 thiab 21, raws;
DIP A22 rau hom A plua plav tawg-pov thawj hauv Zone 22;
DIP B22 rau hom B plua plav tawg-pov thawj ntaus ntawv hauv Zone 22, ntawm lwm tus.
