Guhumeka umuyoboro bisaba ibirenze gutembera mu kirere - bisaba kwizerwa mu gitutu, umutekano ahantu hafunzwe, no kuzigama ingufu zapimwe mu myaka mirongo ikora. Iyo abafana biruka 24/7 mumihanda ya kaburimbo, bisi ya gari ya moshi, cyangwa ibyapa byanjye, inyungu ya 15% ntabwo ari theoretical. Ni 28.000 kWh yazigamye buri mwaka kuri 75 kW imwe imwe. Nibigabanya ubushyuhe bwumuriro kuri moteri. Nibintu bike bitateganijwe guhagarika mugihe cyimodoka nyinshi. Niyo mpamvu abajenjeri bagenda bagaragaza Umufana wo kuzigama sisitemu - ntabwo ari ukuzamura, ariko nkibishushanyo mbonera.
Impamvu abakunzi ba tunnel gakondo bagwa munsi yumutwaro nyawo
Twabibonye mumishinga 37 ya tunnel kuva 2021: abafana bapimwe kuri "82% imikorere" igabanuka kugera kuri 64% mumwanya. Kubera iki? Ubwa mbere, igihombo cyumuvuduko uva kumuyoboro uhengamye, grilles, hamwe nicyuma kizimya umuriro ntigishobora kugereranywa neza mugihe cyo gutoranya. Icya kabiri, voltage sags no kugoreka guhuza ibice bya kure bitesha agaciro imikorere ya moteri ya induction - cyane cyane ku mutwaro igice. Icya gatatu, igice kinini cyumurage kibura ibitekerezo-nyabyo; biruka ku muvuduko uhamye batitaye ku kwibanda kwa CO, kugaragara, cyangwa ubwinshi bwimodoka. Umukiriya umwe mu Ntara ya Gansu yanditse amajwi 41% ku muvuduko wuzuye - nubwo ibyuma byangiza ikirere byerekanaga umwuka uhagije kuri 68% byumunsi.
Igisubizo? Amashanyarazi yashegeshwe, kwihuta kwambara, no kunanirwa igihe kitaragera. Ikibi kurushaho: gahunda yo gufata neza ivura ibimenyetso-ntabwo ari intandaro.
Inzira enye zubwubatsi zitanga kuzigama ingufu nyazo
Nukuri Umufana wo kuzigama imikorere iva muburyo bwiza - ntabwo isasu rimwe rya feza. Dore icyakora mubikorwa:
- EC Kwishyira hamwe: Simbuza moteri ya IE3 isanzwe hamwe na elegitoronike yagabanijwe (EC). Mubisanzwe tugera kuri 89-92% imikorere ya moteri murwego rwa 20-100% - nta gutesha umuvuduko muke. Moteri ya EC nayo ikuraho igihombo cyanyerera kandi igatanga neza neza kugenzura.
- Ikirere cyo mu kirere. Abakunzi bacu ba tunne ya FBD bakoresha CFD yemewe na blade geometrie igabanya igihombo cyatewe numuvuduko ukabije wa 11.3% ugereranije na ISO 13348.
- Guhuza Umutwaro Wubwenge: Hindura ibice bibiri bihindagurika (VFDs) hamwe namakuru yigihe-cyiza cyikirere-ntabwo ari igihe cyateganijwe gusa. Umuyoboro wa fana ebyiri muri Shandong wagabanije gukoresha buri mwaka 33% nyuma yo kongeramo NO₂ hamwe na sensor igaragara ihuza VFD.
- Kubaka-Kurwanya Kubaka: Umwuka wuzuye umunyu, uduce twa mazutu, hamwe nubushuhe bwangiza amazu hamwe na moteri. Ubuso bwangiritse bwongera gukurura no kutaringaniza. Inzu ya Titanium na epoxy yubatswe na carbone ibyuma bigumana ubudahangarwa bwindege mumyaka 15+ - bitandukanye nicyuma cyoroheje kitavuwe, gitakaza imikorere ya 4-6% mumwaka wa 3 wonyine.
Kwimenyekanisha ntabwo ari ubushake-Ntabwo ari ibiganiro
Bamwe barashobora kuvuga ko abafana batari hanze yujuje ibyangombwa bisabwa - kandi barabikora. Ariko kubahiriza byibuze ntabwo byemeza imbaraga zo gukora. Mu mwobo w’amakara hafi ya Xuzhou, abafana basanzwe ba axial bananiwe inshuro nyinshi kubera gukuramo ivu ryamakara hamwe na metani. Gukosora ntibyari imbaraga zisumba izindi-byari icyemezo cyerekana iturika (dⅠ), ibyuma bisize ceramic, hamwe n'inzu zifunze hamwe na azote nziza. Icyo gice ubu gikora amasaha 14,200 nta kubungabunga.
Zibo Hongcheng Fan Co., Ltd yubaka uru rwego rwihariye muri buri Umufana wo kuzigama gahunda. Nta kataloge yatandukanijwe. Nta “moderi isanzwe + yongeyeho.” Ahubwo.
Reba Hanze y'Icyapa - Saba amakuru yemejwe mu murima
Ingufu zisaba ntacyo zisobanura zidafite imiterere. Baza kuri: umurima wapimwe imbaraga zishushanya 30%, 60%, na 100% bitemba; kunyeganyega ku muvuduko wo gukora; na raporo y’ibizamini byabandi kuri GB / T 1236-2017 na ISO 5801.Muri Zibo Hongcheng Fan Co., Ltd., buri mufana wa tunnel akora amasaha 72 yikigereranyo cyamagare mbere yo koherezwa - yuzuye umurongo wo kurwanya imiyoboro, ntabwo ari laboratoire.
Kwishura biragaragara. Umuhanda wa gari ya moshi 2.4 km muri Yunnan wagabanije guhumeka OPEX kuri, 000 187.000 / umwaka ukoresheje abafana bacu ba EC batwarwa na centrifugal tunnel. Kwishura: imyaka 2.8. Icy'ingenzi: zeru zashyizweho ku gahato mu mezi 22 yumurimo.
Umuyaga mwiza wa tuneli utangirira aho théorie ihura na terrain. Irasaba abafana bakoze injeniyeri, itose, umukungugu-ntabwo ari urupapuro gusa. Mugihe umushinga wawe usaba kwizerwa gupimwa mumyaka mirongo hamwe no kuzigama bipimye muri kilowatt-amasaha kuri metero ya bore, tangira ukoresheje umwuka winjiza amafaranga. Tangira na Umufana wo kuzigama yubatswe kumurimo-ntabwo yagurishijwe gusa.
