Sisitemu yo guturika itagira umuyaga ituma ikirere kigenda aho ikirere gishobora gusobanura ibiza. Mu birombe by'amakara, imiyoboro itunganya imiti, cyangwa koridoro ya serivisi ya peteroli, guhumeka ntabwo ari ihumure-ni ukubaho. Twabonye abafana bananiwe mukibazo cyumuriro, umuriro mubi mugihe cya metani, cyangwa korode nyuma y amezi atandatu mumazi yuzuye sulfuru. Niyo mpamvu abajenjeri bagaragaza ibice bitagira umuyaga biturika bitaba amahitamo-ahubwo nibisabwa byibanze.
Impamvu abakunzi ba tunnel isanzwe bananirwa muri zone zangiza
Agace gashobora guhumeka gasaba ibirenze ubwinshi bwumwuka. Irasaba umutekano wimbere-nta nkomoko yo gutwikwa, nta bushyuhe bushyushye, nta nzira isohoka ihagaze. Abafana basanzwe ba axial cyangwa centrifugal bakoresha moteri ya induction hamwe na terefone igaragara, amazu adahumeka, hamwe na karuboni ya karubone arc. Muri Zone 1 (aho umwuka wa gaze ushobora guturika) cyangwa Zone 2 (aho rimwe na rimwe), ibyo biranga kurenga IEC 60079-0 na GB 3836.1.
Twagerageje abafana batatu batagira umuyaga mu kirere cyigana (5.5% CH₄, 22 ° C, 95% RH). Byose byarenze ubushyuhe bwubuso mu minota 47. Ibice bibiri byikubye inshuro; umwe yatwitse gaze ivanze mugihe cyo gutangira kwiyongera. Intandaro? Ibinyabiziga bidafite ibyemezo byemewe, ibyuma bidafite aho bihurira, hamwe na plastike ifata amashanyarazi. Kunanirwa kwisi ntabwo ari theoretical-byanditswe mubuyobozi bwa leta bwubushinwa bushinzwe umutekano wakazi kuva 2022–2023.
Niki Cyakora Umufana Wukuri Guturika?
Umufana wemewe woguturika udashobora guhuza ibice bine bidashobora kuganirwaho: uruzitiro rwa moteri (dⅠ cyangwa Ex d IIB T4), igishushanyo mbonera cya flameproof (ntabwo "irwanya-spark" gusa), ubushyuhe-urwego-rwahujwe nibikoresho, hamwe nimbaraga zingana zemejwe kumuvuduko wa 110%. Urukurikirane rwa FBD (dⅠ) rwuzuzanya rwumuzunguruko wa axial-rwashizweho byumwihariko kumutwe wamakara yo munsi yubutaka - rukoresha moteri ebyiri zidashobora guturika zashyizwe mubirindiro bya aluminiyumu bifite 0.012 mm ntarengwa. Imashini zayo ziruka kuri 1,480 rpm ariko guma munsi yubushyuhe bwa 135 ° C ndetse no kuri 105%. Ntabwo ari kopi yo kwamamaza-ibyo byapimwe amakuru yo muri laboratoire yemewe ya ISO 17025.
Ariko icyemezo cyonyine ntigihagije. Twarebye abakiriya bashiraho abafana bemewe gusa dusanga kugwa kwikirere biterwa no kurwanya imiyoboro idahuye cyangwa kugabanuka kwa voltage hejuru ya metero 800. Igisubizo nyacyo kigomba kubarwa kubijyanye na sisitemu yo murwego rwo hejuru: guhindagurika k'umuvuduko uhagaze, imivurungano yinjira, ingaruka ziterwa n'ubushuhe bw’ibidukikije ku kurwanya moteri, no kugoreka guhuza ibintu biva kuri disiki zihinduka. Niyo mpamvu buri gice cya FBD cyoherezwa hamwe nurubuga rwihariye rwimikorere - ntabwo ari imbonerahamwe ya kataloge gusa - kandi rurimo agasanduku ka gasanduku kamanuka kangana na mm 35 z'umuringa wumuringa.
Customisation ntabwo ari Ibinezeza-Nibikorwa bikenewe
Ingano imwe-ihuza-yose ntikibaho munsi yubutaka. Umuyoboro wa tunnel kuri metero 3.2 z'umurambararo wamakara ukenera imbaraga zitandukanye, urusaku rw urusaku, hamwe na geometrie igenda irenga imwe kuri miti 5.8 m yinjira mumashanyarazi. Twubatsemo ibintu birenga 174 byabigenewe mumezi 27 ashize-harimo na moderi ya titanium yerekana imiyoboro ya H₂S ikungahaye ku miyoboro ya gaz ya flue, ibishushanyo mbonera-bibiri byifashishwa mu guhuza imiyoboro ihumeka, hamwe na verisiyo nkeya-ihinduranya bigabanya ihindagurika ryumvikana mu rukuta rwamabuye.
Ibyingenzi byingenzi byo kwifashisha dusanzwe dukoresha:
- Icyiciro cya moteri: H-urwego rwimikorere, yazamuwe kuri C-urwego rwa> 200 ° C ibidukikije
- Ibikoresho byimuka: Aluminiyumu (isanzwe), ibyuma bitagira umwanda 316 (ibidukikije bya chloride), cyangwa titanium yo mu cyiciro cya 7 (H₂S + umuvuduko mwinshi)
- Imigenzereze: RS-485 Modbus RTU yabanjirije insinga, 4-20 mA ibitekerezo bisa, cyangwa guhagarika byihutirwa guhagarika
- Ingano y'icyemezo: Impamyabumenyi ebyiri kuri GB 3836 na ATEX 2014/34 / EU - byemejwe na CNEX na SGS
Nta gihano cyo kuyobora-gikurikizwa. Umurongo wo gukora modular ufite ibice 12 byingenzi bya moteri, 8 byerekana imashini, hamwe n amazu 5 yimyubakire - byose byabanje kugeragezwa kandi byanditse. Custom spes ifunga mbere yo gutunganya, ntabwo nyuma yinteko.
Imikorere nyayo itangira mbere yo kwishyiriraho
Gutanga ntabwo birangiye. Twakurikiranye ibibazo nyuma yo kwishyiriraho kurubuga 41: 62% byerekanwe kubutaka budakwiye, 23% kumigozi itagabanijwe, na 15% kuburizamo bwinjiriro buterwa nigishushanyo mbonera cyinzibacyuho. Niyo mpamvu buri cyegeranyo gikubiyemo ubufasha bwubushakashatsi bwubusa-ntabwo ari imfashanyigisho za PDF gusa. Itsinda ryacu risubiramo umurongo wawe wambukiranya igice, ibyateganijwe bya gaze, ingufu zituruka kumashanyarazi, hamwe nimbogamizi zo kubona. Twerekana urugero rwimyuka yangirika muri metero 200+ zumuyoboro hamwe nibendera rya voltage kugabanuka mbere yo guca beto.
Zibo Hongcheng Fan Co., Ltd yubaka ibi bice mu kigo cyayo cya 9000 m² Zibo Blower Industrial Park-aho buri mufana akora amasaha 72 yikizamini cyikurikiranwa ryumuvuduko ukabije, hakurikiraho gusuzumwa na termografi no gupima igice. Urabona raporo yikizamini yasinywe, ntabwo ari icyemezo cyanditse. Kuberako iyo methane yibanze kuri 4.3%, icyangombwa ntabwo kubahiriza impapuro-ni ukumenya niba umufana akomeza kuzunguruka.
Kuri ba injeniyeri bagaragaza sisitemu y'abafana batagira ibisasu, ikibazo ntabwo "Ni ikihe kirango?" Ni "Ninde mufatanyabikorwa wumva ko kunanirwa guhumeka atari igihe-ni ibyago." Uku gusobanukirwa gutuye muburyo bwo kwihanganira weld, imbaraga za dielectric ya moteri ihindagurika, hamwe nubushobozi bwa technicien bwo kugenzura ikomeza kubutaka. Aho niho umutekano nyawo utangirira-kandi aho bitagomba kurangirira.
