Hawo-qaadista tunnel-ku maaha dhaqdhaqaaqa hawada-waa ku saabsan badbaadinta nolosha, ka hortagga kororka dabka, iyo ilaalinta feejignaanta darawalka ee meelaha xaddidan, khatarta sare leh. Marka qiiqu buuxiyo tunnel waddo oo 3 kiilo mitir ah inta lagu jiro shil, ilbiriqsi kasta waa la xisaabiyaa. Taasi waa sababta injineeradu aysan u dejin taageerayaasha guud. Waxay cayimeen SDS taxanaha jet taageere unugyo-sax-si sax ah loo farsameeyay, la hagaajiyay, iyo goob-goobeedka oo lagu caddeeyey kadeedka kulka iyo hawada-dhabta ah.
Waa maxay sababta Taxanaha SDS Jet taageerayaashu u keenaan Badbaadada Tunnel-ka-dhabta ah ee aan ahayn tirooyinka socodka hawada
Waxaan aragnay mashruucyo aad u badan oo guuldarreystay-maaha naqshad liidata, laakiin ka yimid xulashada taageereyaasha oo aan is-barbar-dhigin. Marawaxada lagu qiimeeyay 30,000 m³/saacadii macnaheedu waa wax yar haddii isugeynta isugeynta ay hoos ugu dhacdo 18% 55°C ambient ama haddii dhawaaqa daabkiisu uu la socdo dhaqdhaqaaqyada gariirka caadiga ah. The SDS taxanaha jet taageere waxay ka fogaataa hagardaamooyinkan qaabaynta.
Cutub kastaa wuxuu keenaa culays joogto ah oo ka dhan ah baaxadda hawlgalka oo dhan: 1,800-4,200 N taageere kasta, iyadoo ku xidhan moodeelka iyo qaabaynta mootada. Si ka duwan cutubyada axial-ka ee luminaya waxtarka ka sarreeya 45°C, taageerayaasha SDS waxay adeegsadaan dahaarka Heerka H iyo dabaylaha isku dhafan kulaylka leh—oo si joogto ah loogu tijaabiyay 70°C hawo soo galeysa 72 saacadood iyada oo aan waxqabad lahayn. Waxaan xaqiijinay tan intii lagu gudajiray imtixaankii komishanka ee 2023 ee tunnel-ka buurta ee u dhow Lanzhou: saddex SDS-1250 unug waxa ay ilaaliyeen 96.3% ee kicinta la qiimeeyay ka dib 48 saacadood oo hawlgal joogto ah oo ah 62°C jawiga iyo 85% qoyaan qaraabo ah.
Ku rakibidda arrimaha matoorka ayaa la mid ah. Taageerayaasha SDS waxay si toos ah ugu daraan go'doominta gariirka ISO 10816-ku-dhaqanka ee qaabka taageerada-ma jiraan xirmo-alxan leh, ma jiro wax burbursan oo caag ah. Tani waxay yaraynaysaa wakhtiga rakibaadda 40% waxayna meesha ka saaraysaa sababta ugu badan ee dhalmada dhicis ah ee codsiyada tunnel-ka: rarista firfircoon ee si khaldan u keentay.
Maxaa ka dhigaya taageerayaasha SDS inay shaqeeyaan halka ay kuwa kale istaagaan-macno ahaan iyo farsamo ahaanba
Qaar baa laga yaabaa in ay ku doodaan in taageere kasta oo axial-ka ah uu ku filan yahay isticmaalka tunnelka. Si kastaba ha ahaatee, socodka hawada ee tunnel-ka dhabta ah ma aha mid degan - waa la garaacaa, asymmetrical, oo wasakhaysan. Naaftada ayaa qayb ka ah daab jaakad ah. Dabaylaha isdhaafsan ee degdega ah ayaa keena kala soocida socodka. Marinnada baabuurta degdega ahi waxay abuuraan cadaadis dhabarka oo ku meel gaadh ah.
Taxanaha SDS waxa uu qabtaa dhammaan saddexda sababtoo ah waxa lagu dhisay saddex sifo oo aan gorgortan lahayn:
- Ka-hortagga-wareegayaasha laba-geesoodka ah-ma aha oo kaliya kicinta sare, laakiin qulqulka degdega ah dib-u-xoojinta ka dib aagagga dib-u-wareejinta;
- Isku-dhafka ah ee CFD-la xaqiijiyay joomatari shroud-hoos u dhigista khasaaraha tip vortex-ka 22% oo ka soo horjeeda naqshadaha hal-hawlgalayaasha ah (xaqiijinta tunnel dabaysha dhinac saddexaad);
- Fursadaha mootada aan qarxin ee modular3836.1–2021 iyo IEC 60079–0:2017
Waxaan mar ku beddelnay lix da'da oo 110 kW taageere ah tunnel-ka dhuxusha qaada oo leh afar SDS-1600. Isticmaalka tamarta ayaa hoos u dhacay 31%, muddada dayactirka ayaa labanlaabmay, iyo - si dhab ah - nidaamku hadda wuxuu dib u bilaabmaa 2.3 ilbiriqsi gudahood ka dib markii korontadu goysay. Xawaarahaasi wuxuu khuseeyaa marka hawo-qaadashadu ay tahay inay dib u bilaabato ka hor inta aysan heerarka CO jebin 30 ppm.
Is-habaynta Maaha Raaxo-Waa Shuruudaha Saldhigga
Ma jiro laba tunnel oo wadaaga xannibaadyo isku mid ah. Mid ka mid ah wuxuu u baahan yahay iska caabin daxalka ah oo ka dhan ah hawada milixda ee baraf ka saarta. Mid kale wuxuu u baahan yahay baalal titanium ah oo loogu talagalay qiiqa-soo-saarka geotermal-ka baaruudda. Mid saddexaad ayaa dalbanaya ogaanshaha fog ee Modbus TCP oo leh heerkulka dusha sare, gariir, iyo la socodka cudud.

Macmiil ku sugan Jiangsu waxa uu u baahday taageereyaasha SDS tunnelka tareenka badda hoostiisa mara halkaasoo ceeryaamo milixdu ay dhaaftay 500 mg/m³ maalintii. Dahaarka caadiga ah ee epoxy ayaa ku guuldareystay 14 bilood gudahood. Xalka? Garaashyada Titanium + Guryaha mootooyinka dhoobada-dahaarka leh + xidhmooyinka hawada nadiifinta cadaadisay. Lagu keenay 11 toddobaad gudahood—iyada oo aan dib loo dhigin hawlgelinta tunnelka.
Doorashada Taageeraha Saxda ah ee SDS waxay la macno tahay Weydiinta Su'aalaha Saxda ah Marka hore
Ka hor inta aan la cayimin mid SDS taxanaha jet taageere, weydii alaab-qeybiyahaaga shantan su'aalood- oo weydii jawaabo qoran:
- Waa maxay heerka qudhunka riixitaanka ee 65°C iyo 90% RH in ka badan 1,000 saacadood?
- Ma bixin kartaa warbixinnada tijaabada qolo saddexaad oo xaqiijinaysa qiiqa qiiqa ≤78 dB(A) 3 mitir, xaaladaha goobta xorta ah?
- Sideed u xaqiijisaa sharafta qaab dhismeedka aaga seismic Zone 8 (0.3g dardargelinta toosan)?
- Waa maxay wakhtiga u dhexeeya guuldarrooyinka (MTBF) ee matoorka hoos yimaada hawlgalka 24/7 ee joogtada ah?
- Ma bixisaa taageerada hawlgelinta goobta - oo ay ku jirto khariidaynta socodka hawada iyo xaqiijinta cabbirka riixitaanka?
Zibo Hongcheng Fan Co., Ltd. waxay daabacdaa dhammaan xogta tijaabada si hufan. Dukumeentiyadooda taxanaha ah ee SDS kuma jiraan kaliya qaloocyada waxqabadka taagan—laakiin jaantusyada jawaabta firfircoon ee muujinaya wakhtiga soo kabashada ka dib 0-100% isbeddelka tillaabada culeyska, iyo warbixinnada sawirka kulaylka ee xaqiijinaya goobaha kulul inta lagu jiro baaritaanka culeyska xad dhaafka ah.
Badbaadada tunnelku way kobcaysaa. Markaa waa in tignoolajiyada hawo-qaadista. The SDS taxanaha jet taageere ma aha kaliya khad wax soo saar - waa natiijada labaatankii sano ee jawaab celinta goobta, qaabaynta kulaylka ee celceliska ah, iyo anshax wax soo saar eber ah. Marka noloshu ay ku tiirsan tahay socodka hawada, isku halaynta laguma qiyaaso sifooyin. Waxa lagu caddeeyey tunnel-ka qiiqu ka buuxo, 3 subaxnimo, inta lagu jiro duufaantii ugu xumayd sanadka.
