Umuyoboro wo mu kirere washyizweho mugihe cyo gusana inzu cyangwa kubaka inzu yigihugu. Ibicuruzwa byabo by'akato, birumvikana ko bidashobora kwitwa, Isoko ririmo ibikoresho byamoko yose yatekerezwa. Nibyo gusa?
Umuyoboro wo mu kirere ni imiyoboro ya tubular ihindagurika, urukiramende cyangwa elliptike, igamije gutwara umwuka cyangwa izindi gazi. Bitewe numuyoboro usanzwe cyane uturutse kubyuma gakondo (urukiramende no kuzenguruka), ndetse numutungo uhindagurika winzego zinyuranye. Buri kimwe muri ibyo bikoresho gifite ibiranga.
Aho umuyoboro wo mu kirere ukoreshwa
Mu mapanga, imiyoboro yo mu kirere ikoreshwa mugihe ikora sisitemu yo gukora imashini. Ndabashimira, umwuka mwiza wo mu muhanda ugwa mu mpande zitandukanye z'ahantu, kandi nkoresha, yuzuyemo dioxyde de carbon no guhumeka, ava mu nzu. Ntugakore nta miyoboro ikonjesha iyo ushyiraho sisitemu yo guhuza ikirere, aho igice kimwe gikoreshwa mu kirere gitanga ibyumba byinshi hamwe numwuka ukonje cyangwa ushyushye. Umuyoboro ukoreshwa muguhuza umutaka wo mu gikoni ku mwobo uryamye wavanyweho.Ellipse hamwe nibyiza byayo
Umusaruro w'amavi menshi, kanda n'ibindi bintu bifatika bisaba ko filigree yukuri yo gukata urupapuro rwabimwe Byakunzwe. Imiyoboro nkiyi ikunze gukorwa mumikino yo gufunga imizigo yigice cyizengurutse, ibaha eliptique imashini zateguwe byihariye. Inkongi y'umuyaga iroroshye gushyira inyuma yumurizo igisenge, bashiraho imyigaragambyo ntoya kuruta imiyoboro yurukiramende (hamwe nigice kimwe cyurukiramende fungura mu cyumba. Igiciro cyindege kirimo igorofa, ariko, iruta inzira yicyitegererezo, kandi ntushobora kubigura ahantu hose.
Umuyoboro ukoreshwa muburyo bwa mashini gusa, ariko nanone sisitemu ikomeye ya Ventitiatiotors. Birakenewe kandi mugihe cyo kubaka uburyo bwo gushyushya ikirere.
Guhitamo Umuyoboro wo mu kirere ntabwo ari umurimo woroshye. Niba uteganya gushiraho sisitemu yagutse yumuyoboro windege (kurugero, ku gihuha cyangwa gushyushya ikirere), umushinga urasabwa. Igomba kurerwa nubunararibonye buboneye buzabara imikorere isabwa na sisitemu, itezimbere gahunda yo gukora imiyoboro yo mu kirere. Igishushanyo gikwiye kumenya ko umuvuduko wo kugenda mu kirere unyura mu kibuga cyo guturamo ntagomba kurenza 3-4m / s, ubundi urusaku ruzakurakaza. Yoo, ibi bibaho, akenshi kubera kwikinisha abubatsi mumazu menshi agezweho akenshi ntahantu ho kwihitiramo Ventkanalov. Kubera iyi mpuguke zifatika zigomba gukora imiyoboro yo mu kirere ifunganye, kandi umuvuduko wo mu kirere muri byo uhinduka cyane ...
Agace kambukiranya igice cyikirakira cyangwa diameter yumuyoboro uzengurutse ubwikorezi bwikirere kumuvuduko kugeza kuri 4m / s birashobora kugenwa byigenga. Kugira ngo ukore ibi, biroroshye gukoresha isano igereranijwe: s = 0.9 l, aho s ni ntarengwa isabwa ryambukiranya igice (cm2), na l-ikirere (m3 / h) binyuze mumuyoboro wo mu kirere.
Mugutumiza kwishyiriraho umuyoboro windege, ntukanyeganyega kumurimo winzobere nziza. Ibitaro, abashuka baturuka mu guhumeka mu Burusiya akenshi ntibayubahiriza amategeko agenga abanza yo gutondekanya imisoro hagati yabo kandi babamanike kugirango bagarure. Kubwibyo, muri sisitemu yamaze kurangirwa, kubura gukundwa cyangwa gukuraho ikirere akenshi bigaragazwa, kunyeganyega. Izindi ngaruka zisanzwe zibintu byamahanga muri sisitemu yo guhumeka, umwuka wo mu muhanda, ibibi cyangwa birenzeho umwuka uhuha, ndetse no gukwirakwiza imboro no kurenga kubamo. Kubikorwa byo kwishyiriraho, urashobora gukurikirana kubuntu kwishyiriraho no gushiraho sisitemu.
Imigenzo yubusa
Imiyoboro yicyuma yicyuma cyizengurutse kandi yurukiramende hamwe nibice bihuye byakoreshejwe mumyaka myinshi muburyo bwo guhumeka hamwe nuburyo bwo guhumeka hamwe nibikorwa bitandukanye. Kubwimpanuka, basabwe gusaba inzobere muri Yogoko (Abashakashatsi badaharanira inyungu "Abashakashatsi bahanganye, firerique, ibyifuzo byubushyuhe hamwe nibisabwa mubushyuhe hamwe nibyifuzo byubuhanga kugirango itegure ihana ikirere rizengurutse Kubaka "nk'inzira zo gutanga imashini zitangwa na Mechaus Vantilation. Umuyoboro w'icyuma ukomeye wakozwe, uyobowe n'ibisabwa n'ibyangombwa by'inyandiko ngengamikorere, muri ibyo birashoboka kubona BP 353-86 "snup no gukoresha imiyoboro y'indege mu bice bifatika", snup 41-01- 2003 "gushyushya, guhumeka no guhumeka "idr. Hano hari imiyoboro yindege ituruka kubyuma bitandukanye, ariko byiganje muri bo ibicuruzwa biva ku rupapuro rwamaguru.
Gutondekanya. Ukurikije ibyingenzi kandi byikoranabuhanga, imiyoboro izengurutse ibyuma yagenwe ku isoko ry'Uburusiya igabanijwemo umwanda kandi uzunguruka. Iheruka, na none, igabanijwemo spiral-aslad-isudi. Urukiramende rutondekanya uburyo bwo guhuza ibisasu birashobora gutangwa kuri spring no gusudira.
Kuzenguruka ibyuma bizengurutse, diameters yimbere ya 100-2000mm. Harimo moderi ifite diameter 100, 125, 140, 160, 180, 180, 200, 225, mm 250 irakoreshwa. Umuyoboro uzengurutse Air birakunze gukorwa cyane: zirabitswe cyangwa zisudikuke, zihuza impande ebyiri zurubuga rwicyuma, ziruka kuri axis ndende. Uburebure bwabo ni 1; 1.25; 2; 2.5m. Ariko, vuba aha umusaruro uzengurutse umwuka hamwe na spiral-lock-gusudira-gusudira bikozwe ku mashini zidasanzwe ziriyongera ku buryo bugaragara. Uru rubingo rurangwa no kongera ubunini ugereranije. Uburebure bwabo bushobora kuba butagira imipaka (bikunze kugurisha ibice 3 cyangwa 6m), ikidodo gifite ubucucike bwiza, isura ihora ari nziza. Ariko, ibinyobwa byiyongera gato, bigaragarira mubiciro (ingendo za 10-20% bihenze).
Imiyoboro yicyuma yicyuma nayo ifite urukurikirane rwibice bisanzwe byambukiranya amakuru: kuva 100100 kugeza 40003200mm. Uburebure bwa plots itaziguye - 1; 1.25; 2; 2.5m. Urupapuro rwindege rwindege rusanzwe rugaragara neza, ariko hamwe nigice cyiyongera, bahinduka ibintu byinshi, bitorohewe no gutwara no kubika. Izi mpano ziratsindwa mubishushanyo mbonera byindege hamwe nububiko bwa angular latch, bikusanywa kurubuga rwo kwishyiriraho.
Ugereranije n'imiyoboro yindege yuzuye, urukiramende rwindege rurema cyane kumuyaga (ni ukuvuga, mugihe ukoreshwa, ugomba kugura umufana ukomeye), byongera kandi bitanga urusaku. Ariko ni imiyoboro y'urukiramende, mubitekerezo byacu, nibyiza cyane munzu cyangwa inzu yigihugu, kuko byoroshye kwihisha inyuma yumurizo. Hamwe nuburebure bumwe bwuzuye kandi urukiramende rwa cross cross rushobora kuba inshuro 5 (mubisanzwe rwemerewe gutanga imiduka igororotse hamwe na gentio yita kuri 1: 4). Acri ni igice kimwe cyigice cyigice cyikirere kizengurutse ikirere. Abakora umuyoboro uzengurutse muri uru rubanza, impaka: Guhendutse gushyira uduce twinshi twindege ugereranije no gukora urukiramende rumwe. Ibi nukuri mugihe umuyoboro uhumeka ugizwe ahanini nibibanza bitaziguye. Ariko, mumiyoboro myinshi cyangwa nkeya, hafi 30-40% yuburyo bwikirere bwumuyaga bugizwe nibicuruzwa bifatika, umubare wacyo wikubye kabiri kumurongo ibiri uhwanye. Igisubizo nigituba cyikirere-cyikirere cyanze bikunze ikiguzi kirenze urukiramende. Nko urusaku, irashobora guhangana nayo, ikubiyemo ubuso bwimbere bwurukiramende hamwe nibikoresho bikurura amajwi.
Docking nta kibazo. Igice cyo gutandukanya uduce ruzengurutse cyangwa urukiramende rwindege, kimwe nibice bigize ingaruka bya sisitemu yo guhumeka bifitanye isano nuburyo bubiri bwingenzi - flange ya flange. Gitoya ingingo muri sisitemu, ibyiza, ariko ntabwo ari ukuri.
Ikigo cya Flange gikorwa hamwe nubufasha bwa flanges bukosowe kumpera yibice bitaziguye, nibice bigize umwuka. Yabigize mu mbaho z'inguni cyangwa amapine hamwe n'impande (compne "shinooka")). Gufunga flanges kumuyoboro wikirere akenshi bikorwa ku miyoboro yo kwiyuhagira cyangwa hamwe na divets hamwe na divery ya 4-5mm yashyizwe muri 200-250mm, rimwe na rimwe gukoresha gusudira. Mugihe ushyiraho umuyoboro hagati ya flanges kubice byikigereranyo, kasebe ya kasebe cyangwa izindi kashe.
Ihuriro rya Babe bifatwa nkibyiringiro cyane muri iki gihe ushimira kuzigama kw'icyuma no kugabanya ubukana bwakazi, bityo ikiguzi cyo kwishyiriraho. Kubwurukiramende rwindege rwindege, ihuriro ridafite inenge rikoreshwa cyane mugukoresha ibyapa. Nukuri birakoreshwa mugihe ushyiraho imiyoboro yo gushyushya umwuka - imyitozo yo kubaka sisitemu muri Amerika na Kanada yerekanaga ko gukomera gukeya nkikibazo. Induru ya inzererezi yumukino uzengurutse hamwe na diameter ya mm 100-900 ikorwa hakoreshejwe urupapuro rutemba. Mu gihe cyambere, indege ndende yikoranabuhanga ihuza imiyoboro yindege irasanzwe.
Onyanka.

Igice cya kabiri gikaze hamwe na Ducsiyo yindege izunguruka hamwe na diameter ya 100-566mm yagaragaye ku isoko ryikirusiya hashize imyaka 10-15 ishize. Bagomba gukoreshwa gusa niba bidashoboka gushyira imiyoboro yicyuma bifatanye, - nkibice bigize imiterere ya geometrike bigoye, kugirango ushyiremo ibikoresho bya geometrike, kugirango ushyiremo ibikoresho byo guhumeka, abatanga ikirere, bacecetse nibindi bikoresho biherereye muri kasenge. Veerops kubera ikiguzi kinini cyo gukodesha hamwe nigiciro kinini cyo kwishyiriraho umuhigo windege uhereye kurupapuro rwa galivasi igice cya gari ya semi-rigid na fluxible air ikwirakwira kandi bisabwa gukoreshwa mubibanza byo gutura.
Umuyoboro w'indege. Ni umuyoboro, ingurube ikozwe muri tallinum tape ihujwe no guhuza cyane. Iki gishushanyo kibafasha gukoreshwa mugushiraho ibikorwa byubushyuhe -30 ... + 300c. Kubijyanye numuyoboro wikirere ukabije uva ibyuma bidafite ikibazo cyangwa ibyuma byiruka, birashobora gukora muburyo bugoye, ndetse no mubushyuhe bugera kuri 700c. Kurwanya ubushyuhe bwo hejuru biragufasha gukoresha imitwe ya kabiri ya Semi-Rigid ntabwo ari mu miyoboro yo guhumeka no guhumeka ikirere, ahubwo no mu kirere gishyushye no gukuramo umwotsi.
Kugira ngo woroshye ubwikorezi, imiyoboro yo mu kirere yashizwemo ihagaritswe, iba inshuro 5-6 ngufi kuruta uburebure bwa mbere. Ariko, nyuma yo kurambura, ntibigishoboka kongera kubakwama.
Umuyoboro woroshye. Inzozi zemewe ziva muri Semi-Rigid Imiyoboro ikonje irashobora kugoreka inshuro nyinshi, guhagarika no kurambura. Imiterere yabyo itanga ikadiri, igihu cyo kwiranga yicyuma. Igikonoshwa cyoroshye cyibice byinshi byamakosa (Udukoko twindege birashobora gutwara ubushyuhe bwikirere -30 ... + 140c) cyangwa kuramba: karabushya ya chlolodide yatinyutse hamwe na polyemide (kugeza 90c) kuri yo.
Hamwe na ruswa ihindagurika ku isoko, imiyoboro ihindagurika ihindagurika itangwa, igenewe gusa guhumeka na sisitemu yo guhumeka. Umuyoboro ushinzwe ubushyuhe urema ukurikije imiyoboro ihindagurika mu majwi, ku buso bw'amaguru buzwiho ku mwanya wa mm 25 n'ubucucike bwa 8kg / m3, no kuri Amashuri yubushyuhe, igikomo cyo hanze cya Multilayer Aluminium Foil. Ubushyuhe bwuzuye-bukurura amajwi yo guhumeka hamwe na sisitemu yo guhuza umwuka hamwe nigitutu gito kandi giciriritse kigizwe na microporphorimbing air yirukanye yimyenda yuzuye, ibi bikaba hamwe na filseter (ibi birinda ibikoresho byo guhinga ubushyuhe), urwego rwubushyuhe Kwimenyesha hamwe nubunini bugera kuri 25mm nubucucike bwa 16kg / m3 hamwe ninkoni yo hanze ya Multilayer Aluminium Foil.
Ibyiza n'ibibi. Ihinduka ryose ryimiyoboro ya Flexible na Semi ifite rigi ifite misa nto. Ntabwo bakeneye impinduka zidasanzwe, bityo umuyoboro wa Ventilation ufite ibice bike, byoroshya cyane kwishyiriraho. Kugirango uhambire imigabane hagati yabo, kimwe no kubahuza nabatandukanye, kaseti idasanzwe "ya aluminiyumu" na clamp ya plastike ikoreshwa. Idosiye hamwe ningingo zisumbuye ryubushyuhe bwonyine bwindege zigabanuka nazo zifatwa niyi lebon. Hanyuma, kugirango ushyireho, abaguzi batanze guhitamo cyane clamps, guhagarikwa, Mastik Byarimo.d.
Ibibi byindege byose byoroheje kandi byashizweho na kimwe cya kabiri ni aerodynamic ikomeye, bitemerera gukoresha neza iyi nzira muri sisitemu nyinshi cyangwa nkeya zumuyaga.
Kwishyiriraho. Yoo, ibirusiya byinshi bishyiraho tekinoroji yo gushiraho imibugo ihindagurika itamenyereye. Kurugero, bibagirwa ko imiyoboro yoroheje idafite ubushyuhe mbere yo kwishyiriraho igomba kurambura neza, bitabaye ibyo, umwuka uyivamo uzagenda ufite ingorane zikomeye. Iyo unyuze mumiterere ya Wall, amaboko adasanzwe cyangwa impfabusa ntibakunze gukoreshwa. Bamwe kandi ntibazi ko umuyoboro wo mu kirere polyester uzatanga rwose niba ari igihe cyo gukoraho igituba gishyushye. Byongeye kandi, abaturanyi nk'abo bazihutisha inzira yo gusaza umuyoboro nk'uwo. Bikunze kwemerera ikosa rito, icyerekezo cyo kugenda mu kirere mu kirere (cyerekanwe n'umwambi ku gasanduku, no ku muyoboro Tagi). Shira udusimba twikirere nkuko byaguye, tutiriwe utekereza kuri radiyo yabo bigomba kuba bishoboka (byibuze diameter ebyiri), bikoreshwa muguhinduranya imiyoboro mito cyane, guhindura igice cyapa. Bikunze kugaragara hamwe nuburyo bwo gukosora inkono yo kwikuramo ubushyuhe hamwe nintara nta kwambikaho ihuriro hamwe nigitambaro. Nta cyemezo cy'ingirakamaro cyubu buryo, kubera ko kashe nkiyi itazagira ikinyabuho neza; Mubyongeyeho, ubushuhe bushobora kuba bwiza aha hantu (iyo bikoreshejwe muri sisitemu yo guhumeka).
Iyo uhambira umuyoboro woroshye (hamwe cyangwa utitonda), birakenewe kwibuka ko kunyeganyega hagati yingingo ebyiri zumugereka bitagomba kurenga 50m.
