Flame and smoke detector input isolation safety barrier
Pagpapakilala
Ing kaligtasan at pamag-iwas king sunog maulaga ya king nanu mang lugal. importanti la kareng mapanganib a kapaligiran a prone keng api ampo pamanyabog. keng kasu ayni, Intrinsic Safety deng fire detector ampo reng intrinsic safety barriers maragul la pakinabang. Deting espesyal a sistema dinisenyu la para aiwasan ing sunog ampo pamanyabog. agawa da iti kapamilatan ning pamagbawas keng electrical ampo thermal energy keng detector system.
Core points:
nDeng intrinsically safe fire detector ila reng maulaga a paralan ning kaligtasan kareng delikadung kapaligiran a maki explosive gases o flammable substances.
nIng uri ning espesyalistang kasangkapan ayni, pundasyunal yang maglako kareng posibling panganib ning pamanyilab kapamilatan ning mahigpit a pamaglimitu king output ning enerhiyang pang-init a kuryenti.
nkareng matas a panganib a larangan antimo reng petrochemicals, pamaglalang parmasyutika, ampo ing pamitipun kareng mapanganib a materyales, ing teknolohiyang ayni e ya malyaring palitan.
nIng pamag-master kareng katangian ampo kareng applicable scenarios da reng miyayaliwang uri da reng intrinsic safety sensors metung yang susi keng pamaglalang keng metung a eksaktung sistema ning pamag-iwas keng api.
nIng safety performance ampo ing operational stability da reng detector a sertipikadu da reng internasyunal a organisasyun antimo ing Atex opisyal na lang me-verify.
makananu yang gagana ing intrinsic safety fire detector?
nkareng lugal a malyaring masilab ampo makasabog antimo ing oil ampo gas, chemical, ampo ing pamagprosesu keng binutil, deng tradisyunal a fire detector magdalang panganib keng kaligtasan pauli ning posibilidad a makagawa lang electric sparks o surface overheating, kabang deng intrinsic safety (IS) detectors sisiguraduan da ing ligtas a operasyun kareng mapanganib a kapaligiran kapamilatan ning espesyal a disenyu.
nIng kayang core technology atyu ya keng energy limitation mechanism: kapamilatan ning eksaktung pamagkontrol keng current ampo heat energy keng circuit, sisiguraduan na ing gamit e ya magproduce ignition sparks o delikadung matas a temperatura lalam ning nanu mang kundisyun ning obra. Para akwa ing goal ayni, ing sistema kailangan yang mika safety barrier - metung a kritikal a sangkap a maka-install pilatan ning alarm controller ampo ing IS equipment, na epektibung maka-block keng sobrang energy transmission ampo makapanatili keng circuit power lalam ning safety threshold keng sablang oras.
nIting dual protection design (internal energy limitation+external safety barrier) gagawan na ing IS detector ing peka-reliable a solusyun keng pamag-monitor keng api para kareng high-risk a lugal, kabang makatupad ya kareng international explosion-proof standards antimo ing ATEX.
Ing pamamintu at pamantayan da reng intrinsic safety fire detector keng UK
keng UK, atin yang mahigpit a regulasyun para keng pamangamit kareng fire safety equipment kareng delikadung lugal. Ing pamamintu kareng regulasyun a reni ali mu legal a requirement, nune importanti ya para siguraduan ing kaligtasan da reng tauan ampo ing masaleseng operasyun.
Ing susi da reng tuntunan yapin ing Atex Regulations. Deting patakaran menibatan la kareng direktiba ning EU a maglalang king pamisanmetung kareng pamantayan king kaligtasan para kareng kasangkapan a gagamitan kareng lugal nung nukarin malyari lang mika sabog.
Deng regulasyun ning ATEX importanti la para kareng ninu mang gagawang, magtinda, o gagamit safety equipment kareng lugal nung nukarin malyari ing pamanyabog. kareng delikadung lugal kilub ning European Union (kayabe ne ing UK), deng eganaganang kagamitan ampo proteksiun a sistema kailangan lang tuki kareng regulasyun ning ATEX.
Kapitparis | Pamaglarawan |
ATEX Directive 2014/34/EU | Kayabe la kareti deng kasangkapan ampo proteksiun a gagamitan kareng lugal nung nukarin malyari ing pamanyabog. |
IEC 60079 | Metung a set da reng international a tuntunan nung makananu lang ligtas a magdesign, mag-install, ampo gumamit kareng electrical equipment kareng explosive a lugal. |
Ing pamangilala at pamamintu kareng patakaran a reni importanti ya. makasaup ya ini para siguraduan ing kaligtasan nung gagamit kang intrinsic safety fire detectors kareng delikadung lugal.
Mamili kang ustung intrinsic safety barriers
Ikami, ing Beijing Pinghe, bilang metung a matas a kalidad a supplier da reng barriers, atin kaming planung panyulung a maglalang king pamagbawas king sukad da reng barriers, gawang magaan at madaling gamitan, gawang simpling pamag-install, pamagbawas king panganib ning pangabagsak, at pamamie barriers a ganap a makayagpang kareng sistemang prosesu.
Ing kekaming PHD-11TN-11 ampo PHD-22TN-1111 dinisenyu la para gamitan kareng smoke detector.
Ing signal input da reng flame ampo smoke detectors ilapin deng makabukud a safety barriers, na malyaring mamye isolation power kareng flame detectors kareng delikadung lugal. Deng flame detectors maggenerate lang 0-40mA signals na makabukud kareng delikadung lugal ampo mipapadala la kareng ligtas a lugal, atin lang papel keng smoke alarm. Ing produktung ini atin yang output circuit at masanting ya para kareng loop powered DCS/PLC systems.
Ing produktung ayni ali ya mangailangan independenting power supply, at ing input ampo output terminals makabukud la.
