Umtfombo welilangabi kanye nemtfombo wentfutfu lokufakwako kwehlukaniswa nesivimbelo sekuphepha
Setfulo
Kuphepha emlilweni kanye nekuvikela kubaluleke kakhulu kunobe nguyiphi indzawo. Tibaluleke kakhulu etindzaweni letiyingoti letivame kuba nemlilo kanye nekuqhuma. Kulesi simo, . Kuphepha lokungekhatsi tintfo letitfola umlilo kanye netihibe tekuphepha letingekhatsi tizuzisa kakhulu. Letinhlelo letikhetsekile takhiwe kute tivikele imililo kanye nekuqhuma. Bakufeza loku ngekunciphisa emandla agezi kanye nekushisa eluhlelweni lwekutfola.
Emaphuzu lamcoka:
nTintfo letitfola umlilo letiphephile ngekwemvelo tindlela tekuphepha letibalulekile etindzaweni letiyingoti letinemagesi laqhumako noma tintfo letivutsako.
nLoluhlobo lwemishini lekhetsekile lucedza ngalokuyinhloko bungoti bekuvutsa ngekutsi lunciphise kakhulu umphumela wemandla ekushisa agezi.
nEtindzaweni letisengotini lenkhulu letifana nemakhemikhali ephethroli, kukhicita imitsi, kanye nekugcinwa kwetintfo letiyingoti, lobuchwepheshe abutsatfwa esikhundleni.
nKuba nebuciko betimphawu kanye netindzawo letisebentako tetinhlobo letehlukene tetinzwa tekuphepha letingekhatsi kuyintfo lebalulekile ekwakheni luhlelo lwekuvikela umlilo lolucondzile.
nKusebenta kwekuphepha kanye nekusimama kwekusebenta kwetitfombo leticinisekisiwe tinhlangano temhlaba wonkhe letifana ne Atex sekucinisekisiwe ngalokusemtsetfweni.
Sisebenta njani umtfombo wemlilo wekuphepha kwangaphakathi?
nEtindzaweni letivutsako naletiqhumako letifana na oyili negesi, emakhemikhali, kanye nekucubungula tinhlavu, titfo temlilo tendzabuko tibeka bungoti bekuphepha ngenca yekutsi kungenteka kutsi tikhicite tinhlansi tagezi noma kushisa kakhulu emhlabatsini, kantsi titfo tekuphepha tangekhatsi (IS) ticinisekisa kusebenta lokuphephile etindzaweni letikhetsekile letiyingoti envi.
nBuchwepheshe bayo lobuyinhloko bulele endleleni yekunciphisa emandla: ngekulawula kahle emandla lamanje kanye nekushisa esifundzeni, kucinisekisa kutsi lemitfombolusito angeke ikhicite tinhlansi tekuvutsa noma emazinga ekushisa laphakeme layingoti ngaphansi kwanoma ngutiphi timo tekusebenta. Kufeza lomgomo, lendlela kumele ifakwe sivimbo sekuphepha - incenye lebalulekile lefakwe emkhatsini wemlawuli we-alamu kanye nemishini ye-IS, lengavimba ngemphumelelo kudluliselwa kwemandla ngekweqile futsi igcine emandla esiyingi ngaphansi kwemkhawulo wekuphepha ngaso sonkhe sikhatsi.
nLomklamo wekuvikela kabili (kuncishiswa kwemandla langekhatsi+sivimbelo sekuphepha sangaphandle) kwenta umtfombo we-IS ube sisombululo lesetsembekile kakhulu sekugadza umlilo etindzaweni letisengotini lenkhulu, ngesikhatsi uhlangabetana nemazinga emhlaba wonkhe langaqhumi njenge-ATEX.
Kuhambisana kanye nemazinga etinhlolo temlilo tekuphepha letingekhatsi e-UK
E-UK, kunemitsetfo lecinile yekusetjentiswa kwetintfo tekuphepha emlilweni etindzaweni letiyingoti. Kulandzela lemitsetfo akusiyo nje imfuneko yemtsetfo, kepha futsi kubaluleke kakhulu ekucinisekiseni kuphepha kwetisebenti kanye nekusebenta lokubushelelezi.
Isethi lebalulekile yemitsetfo ngu . Imitsetfosimiso ye-Atex. Lemitsetfo isuselwa eticondzisweni te-EU letihlose kuhlanganisa emazinga ekuphepha etintfo tekusebenta letisetjentiswa etindzaweni lapho kungenteka khona kuqhuma.
Imitsetfo ye-ATEX ibaluleke kakhulu kunobe ngubani lokhicita, lotsengisako, nobe losebentisa tintfo tekuphepha etindzaweni lapho kungenteka khona kuqhuma. Etindzaweni letiyingoti ngaphakatsi kwe-European Union (kufaka ekhatsi i-UK), yonkhe imishini kanye netinhlelo tekuvikela kumele tihambisane nemitsetfo ye-ATEX.
Indzinganiso | Incazelo |
Umyalo we-ATEX 2014/34/EU | Loku kufaka ekhatsi imishini kanye netinhlelo tekuvikela letisetjentiswa etindzaweni lapho kungenteka khona kuqhuma. |
IEC 60079 | Isethi yemitsetfo yemave emhlaba yekutsi ungaklama njani ngendlela lephephile, ufake, futsi usebentise imishini legezi etindzaweni letiqhumako. |
Kubaluleke kakhulu kuvisisa nekunamatsela kulemitsetfo. Loku kusita kucinisekisa kuphepha uma usebentisa tintfo tekubona umlilo tekuphepha tangekhatsi etindzaweni letiyingoti.
Khetsa tihibe tekuphepha letifanele
Tsine, iBeijing Pinghe, njengemphakeli wetintfo letivimbelako letisezingeni lelisetulu, sineluhlelo lwekutfutfukisa loluhlose kunciphisa bukhulu betintfo letivimbelako letibonakalako, kwenta kutsi tibe lula futsi kube lula kusebenta, kwenta kube lula kufaka, kunciphisa ingoti yekwehluleka, kanye nekuniketa titfombo letifanele ngalokuphelele tinhlelo tenchubo.
I-PHD-11TN-11 yetfu kanye ne-PHD-22TN-1111 yakhelwe ngco kutsi isetjentiswe netintfo tekutfola intfutfu.
Lokufakwa kwesiginali yetintfo tekutfola lilangabi kanye nentfutfu tindlela tekuphepha letihlukanisiwe, letinganiketa emandla ekuhlukanisa tintfo tekutfola lilangabi etindzaweni letiyingoti. Letintfo letitfola lilangabi tikhicita timphawu te 0-40mA letihlukaniswe etindzaweni letiyingoti bese tidluliselwa etindzaweni letiphephile, tidlala indzima ekuhlaseleni intfutfu. Lomkhicito uniketwa emandla yisekhethi lekhiphako futsi ulungele tinhlelo te-DCS / PLC letiniketwa emandla e-loop.
Lomkhicito awudzingi kuphakelwa kwemandla lokutimele, futsi ematheminali ekufaka kanye nekukhipha ahlukaniswe.
