Indangururamajwi zirinda guturika: Ibintu by'ingenzi n'ikoreshwa ry'inganda

Impamvu Indangururamajwi Zidaturika Zifite Agaciro mu Duce Duteje Akaga

Inganda zikorera ahantu hahindagurika cyane zikeneye imbaraga zikomeyeItangazo rusange n'itangazo rusangesisitemu za (PA/GA) kugira ngo abakozi bakomeze kugira umutekano no gukomeza gukora. Mu duce dufite imyuka itwika, umwuka, cyangwa ivumbi rishobora gushya, ibikoresho bisanzwe by'ikoranabuhanga biteza ibyago bikomeye byo gushya.Indangururamajwi zirinda guturikabyakozwe by’umwihariko kugira ngo bihagarike iki kibazo mu gihe bitanga ubutumwa bw’amajwi n’itumanaho ry’amajwi mu nganda nini kandi zifite urusaku rwinshi.

Gukoresha ibi bikoresho byihariye by’amajwi si uburyo bwiza gusa, ahubwo ni itegeko rikomeye rigenga umutekano mpuzamahanga. Gusobanukirwa amahame y’ubuhanga, ibisabwa mu gutanga icyemezo, n’ibipimo by’imikorere y’amajwi y’indangururamajwi zirinda guturika ni ingenzi ku bahanga mu by’amashanyarazi, abayobozi b’ibigo, n’inzobere mu gutanga amasoko bashinzwe kurinda ahantu hateje akaga.

Uburyo bwo Gusobanura Ibyifuzo by'Indangururamajwi Zidaturika

Kugira ngo umuntu asobanure akamaro k'ibikoresho by'amajwi bidaturika, agomba gusuzuma impande eshatu z'umuriro: lisansi, ogisijeni, n'isoko y'umuriro. Ahantu hateje akaga mu nganda, lisansi (nka methane, hydrogen, cyangwa umukungugu w'ibinyampeke) na ogisijeni bikunze kugaragara mu kirere. Ihindagurika ryonyine rishobora kugenzurwa ni isoko y'umuriro. Indangururamajwi zisanzwe zikoresha ibyuma by'amajwi, transformateur, n'insinga zishobora gutanga ibishashi by'amashanyarazi cyangwa ubushyuhe bwo hejuru burenga urugero rw'ibintu bihindagurika. Urugero, ingufu nkeya zo gutwika (MIE) ku mvange ya hydrogen-air ni nke cyane, ingana na 0.017 mJ. Indangururamajwi zisanzwe zo mu bucuruzi zishobora gutanga ingufu zirenze cyane urwo rugero mu gihe cy'imikorere isanzwe cyangwa ikibazo cy'ikosa.

Indangururamajwi zidaturika zigenewe gukuraho indangururamajwi nk'isoko y'umuriro ifatika. Ibi ntibigerwaho binyuze mu kubuza ikirere gihindagurika kwinjira muri icyo gikoresho, ahubwo ni mu kwemeza ko umuriro w'imbere ucungwa kandi uzimwa mbere yuko ukwirakwira mu kirere cyo hanze. Iyi mpinduka y'ibanze mu buhanga igena amahitamo akomeye y'ibikoresho, ubushobozi bwo kwihanganira imiterere, n'ingamba zo gucunga ubushyuhe zikoreshwa muri ibyo bikoresho.

Ingaruka z'ingenzi mu mikorere mu itumanaho rishobora guteza akaga

Itumanaho mu turere dufite akaga ryinshi rirangwa n’imbogamizi zidasanzwe mu mikorere, zitarenze ibyago byo guturika by’impanuka. Ahantu hakorerwa inganda nko mu nganda zitunganya imyanda, aho gucukura imyanda mu mazi, n’inganda zitunganya imiti birangwa n’urusaku rwinshi mu kirere. Urusaku rw’inyuma ruturuka kuri compressors, turbines, n’imashini ziremereye rukunze gukora hagati ya 85 dB (A) na 110 dB (A). Muri ibyo bihe, ingaruka nyamukuru mu mikorere ni ugupfuka amajwi, aho inzibutso z’umutekano cyangwa amabwiriza y’amajwi yihutirwa adasobanutse.

Kugira ngo ugabanye ibi byago bisaba indangururamajwi zirinda guturika zishobora gukora urwego rw'umuvuduko w'amajwi (SPL) rwinshi zitabangamiye icyemezo cy'ahantu hashobora guteza akaga. Itegeko risanzwe rigena ko amajwi y'inkuba agomba kurenza urusaku rw'inyuma ho nibura 10 kugeza 15 dB (A) kugira ngo hamenyekane neza. Kubera iyo mpamvu, agace gafite urusaku rw'inyuma rwa 95 dB (A) bisaba ko ijwi ry'inyuma rigera kuri 105 dB (A) kugeza 110 dB (A) aho umuntu yumva aherereye. Kunanirwa kugera kuri ibi bivamo "ahantu hapfuye" cyangwa igicucu cy'inyuma, byangiza cyane amategeko y'umutekano w'ahantu hose no kongera igihe cyo guhunga mu gihe cy'impanuka zikomeye.

Ni iki gisobanura umuvugizi udaturika

Amagambo "adashobora guturika" akunze kumvikana nabi mu nganda. Ntibisobanura ko indangururamajwi idashobora kwangirika cyangwa ngo ishobore kurokoka iturika ry’inyuma ry’ingufu. Ahubwo, bivuze ko agace k’igikoresho kakozwe kugira ngo gashyiremo iturika ry’imbere ry’imvange y’umwuka cyangwa umwuka ushobora gushya, bikarinda umuriro w’ikirere kibikikije.

Ubu bushobozi bwo kubika amakuru bushingiye ku buhanga buhanitse bw’imashini, ubumenyi buhanitse bw’ibikoresho, n’ibice byihariye by’ijwi bitandukanya indangururamajwi zirinda guturika n’izindi ndangururamajwi zikomeye cyangwa zirwanya ikirere.

Igishushanyo mbonera cy'aho gufungira, inzira z'umuriro, n'ifungwa

Uburyo bw'ingenzi bw'indangururamajwi idaturika (Ex d) ni imiterere y'aho ifungiye no gushyira mu bikorwa inzira z'umuriro. Iyo gazi ihindagurika yinjiye mu nzu y'indangururamajwi igashya n'ikosa ry'amashanyarazi imbere, guturika kwayo gutera umuvuduko mwinshi imbere. Inzu igomba kugira imbaraga zihagije za mashini kugira ngo ishobore kwihanganira uyu muvuduko idacika. Icy'ingenzi kurushaho, imyuka ikura kandi ishyushye cyane igomba gusohoka mu kirere mu buryo bwizewe kugira ngo hirindwe ko inzu ihungabana ryangirika.

Iyi nzira ihumeka inyura mu nzira z'umuriro zikozwe neza neza—icyuho kiri hagati y'ubuso bw'aho urugo ruhurira. Izi nzira zakozwe zifite uburebure bwihariye n'ahantu hagenzurwa cyane, akenshi zikozwe ku buryo burenze milimetero 0.15. Uko gazi ishyushye inyura muri izi nzira ntoya, ihita itakaza ingufu z'ubushyuhe vuba. Mu gihe gazi isohoka mu rugo, ubushyuhe bwayo buba bwagabanutse munsi y'ubushyuhe bwikora bw'ikirere cyo hanze, bizimya umuriro neza kandi bikarinda ko hanze hakwirakwira. Byongeye kandi, imiyoboro yihariye y'icyuma ikunze gukoreshwa hejuru y'ihoni y'ijwi cyangwa ifunguye ry'umushoferi kugira ngo amajwi agende neza mu gihe akora nk'ubushyuhe bukonjesha imyuka isohoka.

Ibipimo ngenderwaho byo kugereranya indangururamajwi zidaturika

Mu gusuzuma indangururamajwi zirinda guturika, guhitamo ibikoresho bifunze ni cyo gipimo cy’ingenzi cyo kugereranya, bigira ingaruka ku kuramba, uburemere, no kuba bikwiranye n’ibidukikije runaka. Ibikoresho bitatu by’ingenzi bikoreshwa mu nganda ni Aluminium idafite umuringa, Polyester ikoresha ibirahure (GRP), na Stainless Steel 316L.

Aluminium itanga uburyo bwiza bwo gukwirakwiza ubushyuhe n'imiterere yayo ku giciro gito, bigatuma ikoreshwa ahantu hose ku nkombe. GRP itanga uburyo bworoshye kandi burwanya ingese cyane, bwiza cyane mu bidukikije bibi bya shimi aho ibyuma bishobora kwangirika. Ibyuma bitarangirika 316L bigaragaza urwego rwo hejuru, bitanga ubudahangarwa budasanzwe ku gusukura umunyu n'ibintu bihumanya, bigatuma iba amahitamo nyayo ku nganda zo mu mazi n'inganda zikomeye.
