Mpweya wa ngalande umalephera—osati chifukwa cha kusowa kwa mpweya, koma chifukwa cha kuvunda kochititsidwa ndi dzimbiri. Tazionera tokha: mafani omwe amaikidwa muzitsulo za zomera za mankhwala amataya umphumphu mkati mwa miyezi 18; Ngalande za m'mphepete mwa nyanja za m'mphepete mwa nyanja zimati zatsekereza nyumba pambuyo pa nyengo imodzi yokha yozizira; ngakhale misewu ya metro yokhala ndi konkriti imapangitsa kuti pakhale kupsinjika koyendetsedwa ndi kloridi mozungulira ma flanges okwera. Kuwonongeka sikumadziwonetsera kokha ndi ma alarm - kumanong'oneza chifukwa cha kuchepa kwapang'onopang'ono, kugwedezeka kwamphamvu, ndi maulendo osadziwika bwino. Chifukwa chake a Chifaniziro cholimbana ndi dzimbiri si chowonjezera. Ndilo chofunikira choyambirira cha mpweya wabwino chomwe chimakhalapo.
Chifukwa Chake Ma Fani Okhazikika Amalephera Mobisa-ndi Zomwe Zimagwira
Mafani ambiri amatengera mpweya wozungulira. Misewu yeniyeni imatulutsa mpweya wa asidi, nkhungu yodzaza mchere, sulfure dioxide kuchokera ku utsi wa dizilo, kapena kuphatikizira kwa condensate pamalo otsika. Nyumba zazitsulo za kaboni zimawononga 0.1-0.3 mm/chaka m'malo oterowo - zokwanira kusokoneza kusasunthika kwa kapangidwe kake mkati mwa zaka zisanu. Aluminium imakana mchere koma imasungunuka muutsi wa acidic. Stainless 304 imagwira kuwonetseredwa pang'ono koma imavutitsidwa ndi intergranular pafupi ndi ma welds pomwe ma kloridi akhazikika. Kukonza sichitsulo chokhuthala. Ndiwophatikiza zinthu mwanzeru komanso chitetezo chapanthawi yake.
Zibo Hongcheng Fan Co., Ltd. amapangira izi m'gawo lililonse. Mafani awo osagwirizana ndi dzimbiri amagwiritsa ntchito njira ziwiri zodzitetezera: zida zoyambira za ASTM A588 zitsulo (zokhala ndi copper-chromium-nickel alloying) kuti zikhazikike mokhazikika kwa okusayidi, kuphatikiza zokutira zosakanizidwa za epoxy-polyester zovotera ISO 12944 C5-M (mulingo womiza m'madzi). Pazovuta kwambiri - monga ma ducts a gasi a flue kapena ngalande za desulfurization - amaphatikiza titanium alloy impellers (Giredi 2 kapena Grade 7), kuyesedwa ku ASTM B348 tensile zokolola> 345 MPa ndi corrosion rate <0.025 mm/chaka mu 10% H₂SO₄ pa 60 ° C. Palibe zokutira "zofanana ndi zonse". Chidziwitso chilichonse chimatengera chemistry yeniyeni - osati zongoganiza za labu.
Zochitika Zenizeni Zapadziko Lonse Zimafuna Kupitilira Dzimbiri Kukaniza
Kukana kwa dzimbiri kokha kumatanthawuza pang'ono ngati wowotchayo sangathe kupitiriza kugwira ntchito. Tawonanso makonzedwe 12 oyika mumphangayo pomwe mafani adachita mayeso opopera mchere koma adalephera kutsimikizira - chifukwa kunjenjemera kunakwera pa 72 Hz chifukwa cha masamba osalinganizika a titaniyamu, kapena chifukwa chakukula kwamafuta akusemphana ndi zisindikizo za epoxy pakuyenda panjinga 40 ° C tsiku lililonse. Zibo Hongcheng amayankha njira zobisika izi:
- Kulinganiza kwamphamvu ku ISO 1940 G2.5-osati G6.3 - yotsimikiziridwa ndi katundu, osati yopanda ntchito
- Kuchulukitsa kwamafuta owonjezera m'mafelemu okwera, pogwiritsa ntchito ma shimu a bimetallic m'machubu apakati -20°C mpaka +65°C
- Seal geometry yotsimikizika motsutsana ndi 10⁵ mizunguliro yamphamvu (kuyerekeza zaka 20 za damper actuation)
- Kutchinjiriza kwa mota kudavotera F-class (155°C), yokhala ndi zokutira zofananira pa ma windings a kukana kwa chinyezi
Mafani awo a FBD amatha kugwira ntchito mosalekeza pa 4,500 Pa static pressure ndi 120,000 m³/h kutuluka—popanda kuwononga malire a dzimbiri. Izi ndichifukwa choti kuwongolera kwa dzimbiri kumalumikizidwa ndi kapangidwe ka makina, osati kumangiriridwa ngati kuganiza motsatira.
Kusintha Mwamakonda Anu Komwe Kumagwirizana ndi Zenizeni Zapatsamba—Osati Mapepala a Catalog
“Kusachita dzimbiri” kumatanthauza zinthu zosiyanasiyana mumsewu wa mgodi wa malasha motsutsana ndi ngalande yapansi panthaka motsutsana ndi ngalande yoyeretsera madzi oipa. Otsatsa ena amapereka njira zitatu zokutira ndikuzitcha makonda. Zibo Hongcheng amawona projekiti iliyonse ngati vuto laukadaulo wazinthu. Amapempha zambiri zokhudzana ndi malo: pH ya zitsanzo za condensate, mitengo ya SO₂, chloride ion ppm m'madzi otsuka, ngakhale mame a nyengo. Kenako amasankha—osati kulamula.
Mwachitsanzo: ngalande yomwe ili pafupi ndi doko la Qingdao imafunikira kukana kwa NaCl aerosol *ndi* kuwonongeka kwa UV chifukwa cha masana. Standard epoxy yellowed ndi chipped. Yankho lawo? Chovala chapamwamba cha fluoropolymer pamwamba pa choyambira chokhala ndi zinc, chogwiritsidwa ntchito ndi mitu yopopera ya robotic pakuwongolera makulidwe a ± 5 μm. Nthawi yobweretsera: masabata a 6-osati 12. Palibe kunyengerera pa certification: mayunitsi onse amanyamula zizindikiro za CE, CCC, ndi ATEX Zone 1/21 pamene pakufunika. Mwambo sikutanthauza kuchedwa. Zimatanthawuza zoyenera-zolinga, zotsimikiziridwa musanatumizidwe.
Kufunika Kwanthawi Yaitali Kumayamba Ndi Kuyika-ndikupitilira Pambuyo Kutumiza
Wokupiza mumphangayo wosachita dzimbiri amabwezera m'chaka chachitatu-osati chaka choyamba. ROI yake imatuluka munthawi yopewera: palibe zotsekera zosakonzekera kuti zisinthidwe, palibe kubweza kwadzidzidzi kwagalimoto chifukwa cha kulowetsedwa kwa chinyezi, palibe kulimbitsa kwamabulaketi okwera. Koma mtengo umadalira kutumizidwa koyenera. Zibo Hongcheng imapereka zida zoyikira zosinthidwa kukhala mumsewu wa geometry - osati mapaketi amtundu wamba. Mainjiniya awo amatsimikizira ma torque a nangula motsutsana ndi kachulukidwe ka gawo lapansi (gawo la konkire, kulimba kwa cholumikizira cha shotcrete), sinthani ma inlet cone ma profaili omwe alipo, ndikutsimikizira zokwera zodzipatula zokhazikika pamafuriji omveka pansi pa 12 Hz.
Kuyika pambuyo, amatsata magwiridwe antchito pogwiritsa ntchito ma sensor a IoT omwe angasankhe - kuyang'anira kutentha kwa delta, ma harmonics apano, ndi kupatuka kwa mpweya motsutsana ndi maziko. Zomwe zikuwonetsa kuchepa kwa 3.2% m'miyezi isanu ndi umodzi, gulu lawo limazindikira ngati likuwonongeka, kuyambika kwa dzimbiri, kapena kutambasula lamba - zisanalephere. Izi si ntchito. Imagwira ntchito mopitilira muyeso.
Kwa ngalande zomwe mpweya wabwino suli bwino - ndi chitetezo cha moyo - a Chifaniziro cholimbana ndi dzimbiri ayenera kupeza dzina lake tsiku lililonse. Osati mu labu. Osati pa pepala. Mu chinyontho, mankhwala yogwira, kugwedera-makonda zenizeni za zomangamanga mobisa. Zibo Hongcheng Fan Co., Ltd. imamanga mafani omwe amapambana mayeso-osati kamodzi, koma kwa zaka khumi ndi zisanu. Chifukwa mpweya wokhalitsa suyamba ndi mawonekedwe a mpweya. Zimayamba ndi zida zomwe zimakana kudzipereka.
