Mei le meikhu hmuh khawhnak thilri luhternak i thleidannak himnak khamnak
Theihternak
Meikanghnak himnak le khamnak cu khoika hmun paoh ah a biapi tuk. Meikanghnak le puahkehnak a chuahter khomi ttihnung pawngkam ah an biapi khun. Hi kongah, Chunglei Himnak meikang hngalh khawhnak thilri le a chunglei himnak khamnak hna cu ṭhatnak tampi an ngei. Hi special system pawl hi meikanghnak le puahkehnak khamnak caah sermi an si. Mah cu hmuh khawhnak thilri chung i electric le lumnak thazaang tlawmternak in an tuah khawh.
A biapi bikmi:
nA chunglei in a himmi mei hngalh khawhnak thilri hna cu a puak khomi thli asiloah mei a kang khomi thilri a ummi ttihnung pawngkam ah himnak caah a herhmi thilri an si.
nHi bantuk thilri ttha nih hin electric lumternak thazaang chuahmi kha fek tein rikhiah in a chuak khomi mei kanghnak ttihnung kha a hrampi in a hloh.
nPetrochemicals, sii sernak, le thil ttihnung chiahnak tibantuk tihnung a sangmi rian ah, hi thiamnak hi thlen khawh a si lo.
nIntrinsic safety sensor phunphun hna i an sining le hman khawhmi thil sining hna kha thiam cu a dikmi mei khamnak system sernak ah a biapi tukmi thil pakhat a si.
nRamkip bu hna nih an cohlanmi hmuh khawhnak thilri hna i himnak riantuan ning le riantuan ning fekmi cu Atex phungning tein fehter an si cang.
A chunglei himnak meikang hngalh khawhnak nih zeitindah rian a ttuan?
nOil le gas, chemical, le rawlchuannak tibantuk meikanghnak le puak khawhnak hmun ah, hlanlio meikangh hngalh khawhnak nih himnak caah tihnung a chuahter, zeicahtiah electric meihol a chuahter khawh asiloah a cunglei a lin tuk khawh, cu lioah himnak (IS) hngalh khawhnak nih a hleiin suaimi hmangin tihnung pawngkam ah him tein riantuan khawhnak a tuah.
nA hrampi thiamnak cu thazaang tlawmternak mechanism ah a um: circuit chung i a tu lio le lumnak thazaang kha ttha tein uknak thawngin, thilri nih zeibantuk riantuannak dirhmun hmanh ah meikhu asiloah ttihnungmi lumnak sang a chuahter lai lo ti kha a hngalhter. Hi tinhmi tlinter awkah, system cu himnak khamnak he aa thuam a hau - alarm controller le IS thilri karlak ah chiahmi a biapi tukmi thilri, cu nih cun a hlei in thazaang kuatnak kha ttha tein a kham khawh i himnak tlukruannak tang ah circuit thazaang kha a zungzal in a chiah khawh.
nHi kilvennak suaisam pahnih (chunglei thazaang tlawmternak+lenglei himnak dawnkhantu) nih IS hmuh khawhnak cu ATEX tibantuk ramkip puahnak khamnak phunglam a tlinh lio ah, tihnung hmun hna caah meikanghnak zohkhenhnak ah zumhawktlak bikmi a siter.
UK ram chung i a chunglei himnak meithat hmuh khawhnak thilri hna i zulhphung le phunglam hna
UK ahcun, tihnung hmun ah meikanghnak thilri hmannak kongah phunglam fek tein an ser. Hi phunglam hna zulh cu upadi nih a herhmi lawng si loin riantuantu himnak le tluang tein riantuannak caah a biapi tukmi a si.
A biapi bikmi phunglam hna cu Atex phunglam. Hi phunglam hna hi EU nawlpeknak in lakmi an si i, puahkehnak a chuah khawhnak hmun ah hmanmi thilri hna caah himnak phunglam hna kha i fonh ding in timhtuahnak an ngei.
ATEX phunglam cu puahkehnak a chuah khawhnak hmun ah himnak thilri a sertu, a zuarmi, asiloah a hmangmi paoh caah a biapi tukmi a si. European Union (UK telh in) chung i tihnung hmun hna ah, thilri le kilvennak thilri vialte nih ATEX phunglam kha an zulh a hau.
Tahfung | Langhtermi |
ATEX Directive 2014/34/EU | Mah ah hin puahkehnak a chuah khawhnak hmun ah hmanmi thilri le kilvennak thilri hna aa tel. |
IEC 60079 | A puak khomi hmun ah electric thilri pawl zeitindah him tein suai, chiah le hman ding timi ramkip phunglam hna. |
Hi phunglam hna hngalhthiam le zulh cu a biapi tuk. Mah nih hin tihnung hmun ah a chunglei himnak meikang hngalh khawhnak thilri hman tikah himnak a bawmh.
Aa tlakmi chunglei himnak khamnak kha thim
Kannih, Beijing Pinghe, a sangmi dawnkhantu thilri a kan petu kan si bantukin, dawnkhantu thilri pawl a ngan ning tlawmter, a ritmi le hman a fawimi siter, chiahnak a fawiter, a tlamtlin lonak ttihnung zorter, le thil kalning system caah aa tlakmi dawnkhantu thilri pawl pek ding timi tthanchonak timhtuahnak kan ngei.
Kan PHD-11TN-11 le PHD-22TN-1111 cu meikhu hmuh khawhnak thilri he hman ding in a hleiin sermi an si.
Mei le meikhu hmuh khawhnak thilri hna i an signal luhternak cu a dang tein chiahmi himnak khamnak a si, cu nih cun ttihnung hmun ah meikhu hmuh khawhnak thilri hna kha a dang tein chiah khawhnak thazaang a pek khawh hna. Meikang hngalh khawhnak nih 0-40mA signal a chuahter i cu cu tihnung hmun hna in a dang tein a um i a himnak hmun ah a kuat hna, meikhu ralrin peknak ah rian a ttuan. Hi thilri cu chuahnak circuit in thazaang a pek i loop thazaang a ngeimi DCS/PLC system caah aa tlak.
Hi thilri nih hin amah tein mei a herh lo, cun luhnak le chuahnak terminal pawl cu an i then.
