Ikoreshwa rya gaze yuburozi, iri jambo ryumwuga risa nkaho ritamenyerewe, kandi ntirishobora kuboneka mubuzima busanzwe, kubwibyo tuzi bike cyane kuri ubu bumenyi, ariko mu nganda zimwe na zimwe, ibikoresho nkibi birakenewe kugirango bikore.Urebye imikorere, reka tugendere muri iyi si idasanzwe yamazina kandi twige ubumenyi bwumutekano.
Icyuma cyangiza uburozi - Ikoreshwa mugutahura imyuka yubumara (ppm) mukirere gikikije.Imyuka nka karubone monoxide, hydrogen sulfide na hydrogen irashobora kuboneka.Ibyuma byangiza ubumara bigabanijwemo ibyuma byangiza ubumara bwangiza kandi byangiza imyuka yubumara.Ibicuruzwa byizewe imbere nibicuruzwa bifite umutekano imbere bishobora gukoreshwa mubihe bibi cyane.
Ibiranga: 0, 2, 4 ~ 20, 22mA ibisohoka / ikimenyetso cya bisi ya Modbus;imikorere yo gukingira byikora kugirango irinde gaze cyane;ibyuma bisobanutse neza, birwanya uburozi byinjira mu mahanga;insinga ebyiri za kabili, zoroshye gushiraho kurubuga;urugereko rwa gaze rwigenga Imiterere na sensor biroroshye kubisimbuza;urutonde rwimikorere ihuza porogaramu isohoka;byikora zeru ikurikirana nindishyi zubushyuhe;urwego rutagira ibisasu ni ExdⅡCT6.
Ihame ryakazi: Ikimenyetso cya gaze yaka / uburozi cyerekana ibimenyetso byamashanyarazi kuri sensor, hanyuma nyuma yo gutunganya amakuru yimbere, isohora ikimenyetso cya 4-20mA cyubu cyangwa ikimenyetso cya bisi ya Modbus ihuye nubunini bwa gaze.
Ibyuma byangiza ubumara mubikoresho byo kurwanya umuriro bishyirwa mubikorwa bya peteroli.Ni ubuhe buryo bwo gushyiraho ibyuma byangiza uburozi muri “Code of Design of Gas Flammable Gas and Toxic Gas Detection and Alarm in Enterprises Petrochemical” byateganijwe n'inzego za leta?Ibisobanuro byo kwishyiriraho ibyuma byangiza ubumara byerekanwe hano hepfo kugirango bitange umurongo wa buriwese gushiraho ibyuma byangiza.
SH3063-1999 “Ibigo bikomoka kuri peteroli n’ibicuruzwa byaka umuriro n’uburozi bwa gazi y’ubumara bwerekana” byerekana:
1) Ibyuma byangiza uburozi bigomba gushyirwaho ahantu hatagira ingaruka, kunyeganyega, hamwe nimbaraga zikomeye za electronique, kandi hagomba gusigara hafi ya 0.3m.
2) Mugihe cyo kumenya imyuka yubumara kandi yangiza, detector igomba gushyirwaho muri 1m uvuye aho irekura.
a.Mugihe hamenyekanye imyuka yubumara kandi yangiza kurusha ikirere nka H2 na NH3, icyuma gipima ubumara kigomba gushyirwaho hejuru yisoko.
b.Iyo ubonye imyuka yubumara kandi yangiza iremereye kuruta umwuka nka H2S, CL2, SO2, nibindi, icyuma gipima uburozi kigomba gushyirwaho munsi yisoko.
c.Mugihe hamenyekanye imyuka yubumara kandi yangiza nka CO na O2 uburemere bwihariye buri hafi yumuyaga kandi byoroshye kuvangwa numwuka, bigomba gushyirwa mumwanya byoroshye guhumeka.
3) Kwishyiriraho no gukoresha insinga za gaze zifite ubumara bigomba kubahiriza ingingo zijyanye na GB50058-92 “Kode yo gushushanya ingufu z'amashanyarazi zo guturika n’ibidukikije byangiza umuriro” hiyongereyeho ibisabwa byagenwe nuwabikoze.
Muri make: kwishyiriraho ibyuma byangiza uburozi bigomba kuba mumaradiyo ya metero 1 hafi y’ahantu hashobora kumeneka nka valve, imiyoboro ihuza imiyoboro, hamwe n’isoko rya gaze, hafi bishoboka, ariko ntibigire ingaruka ku mikorere y’ibindi bikoresho, kandi gerageza wirinde ubushyuhe bwinshi, ibidukikije byinshi nubushuhe bwo hanze (nko kumena amazi, amavuta nibishobora kwangirika kwa mashini.) Mugihe kimwe, bigomba kwitabwaho kugirango bibungabungwe byoroshye na kalibrasi.
Usibye kwitondera kwishyiriraho neza no gukoresha ibyuma byangiza uburozi, kubungabunga umutekano wimashini nabyo ni ibintu bidashobora kwirengagizwa.Ibikoresho byo kuzimya umuriro bifite igihe runaka cyo kubaho, kandi nyuma yigihe cyo kubikoresha, hazabaho ibibazo byubwoko bumwe cyangwa ubundi, kandi ni nako bimeze no kumashanyarazi ya gaze.Nyuma yo gushiraho icyuma gipima ubumara, amakosa amwe arashobora kugaragara nyuma yo gukora mugihe runaka.Mugihe uhuye nikosa, urashobora kwifashisha uburyo bukurikira.
1. Iyo gusoma bitandukanije cyane nukuri, igitera kunanirwa gishobora kuba ihinduka ryimyumvire cyangwa kunanirwa kwa sensor, kandi sensor irashobora kongera guhinduka cyangwa gusimburwa.
2. Iyo igikoresho cyananiranye, gishobora kuba insinga irekuye cyangwa izunguruka;sensor yangiritse, irekuye, izunguruka ngufi cyangwa yibanze cyane, urashobora kugenzura insinga, gusimbuza sensor cyangwa kwisubiramo.
3. Iyo gusoma bidahindagurika, birashobora guterwa no guhagarika ikirere mugihe cyo guhinduranya, kunanirwa kwa sensor, cyangwa kunanirwa kwizunguruka.Urashobora gusubiramo, gusimbuza sensor, cyangwa ukohereza mubisosiyete kugirango bisanwe.
4. Iyo umusaruro uriho urenze 25mA, umuzunguruko usohoka urimo amakosa, birasabwa kohereza mubisosiyete kugirango ubungabunge, kandi andi makosa arashobora no koherezwa mubigo kugirango bibungabunge.
