Kufefetedza kwemugero kunokundikana—kwete kubva pakushaikwa kwemhepo, asi kubva pakuora kunokonzerwa nokuora. Isu takazviona isu: mafeni akaiswa mumakemikari emiti tunnels anorasikirwa nekuperera kweblade mukati memwedzi gumi nemasere; mahombekombe egungwa-giredhi-giredhi tunnels anoshuma kudzika padzimba mushure mekutenderera kumwe chete kwechando; kunyange kongiri-yakamisikidzwa metro tunnels inogadzira chloride-inotyairwa kushushikana inopwanya kutenderedza inokwira flanges. Corrosion haizvizivise nemaalarm-inozevezera kuburikidza nekurasikirwa zvishoma nezvishoma, kuzunguzika kuri kuwedzera, uye nzendo dzemotokari dzisina kutsanangurwa. Ndicho chikonzero a Kuora-resistant tunnel fan haisi yekusimudzira. Ndiyo yekutanga inodikanwa yekufefetera iyo inogara.
Nei MaFans Akajairwa Achikundikana Pasi Pevhu-uye Chii Chinobata
Mazhinji mafeni etunnel anotora ambient air. Matanho chaiwo anoburitsa acid mhute, mhute ine munyu, sulfur dioxide kubva kune dhiziri, kana condensate pooling panzvimbo dzakaderera. Carbon steel housings corrode at 0.1–0.3 mm/gore munzvimbo dzakadaro-zvakakwana kukanganisa kuoma kwemaitiro mukati memakore mashanu. Aluminium inodzivisa munyu asi inonyunguduka muhutsi hune acidic. Stainless 304 inobata kuratidzwa zvakapfava asi inotambura kurwiswa kwepakati padyo nemawelds kana ma chlorides akatarisana. Kugadzirisa haisi simbi yakakora. Ihwo hungwaru hwekubatanidza zvinhu uye process-level kuchengetedza.
Zibo Hongcheng Fan Co., Ltd. vanogadzira chokwadi ichi muchikamu chose. Mafeni emugero anodzivirira kupisa anoshandisa dual-layer dziviriro: zvimiro zveASTM A588 weathering simbi (ine copper-chromium-nickel alloying) kuti iite passive oxide kugadzikana, pamwe nesarudzo epoxy-polyester hybrid coating yakayerwa kuISO 12944 C5-M (mugungwa kunyudzwa level). Pazviitiko zvakanyanyisa — senge flue gas ducts kana desulfurization tunnels — iwo anobatanidza titanium alloy impellers (Grade 2 kana Grade 7), akaedzwa kune ASTM B348 tensile goho > 345 MPa uye corrosion rate <0.025 mm/gore mu10% H₂SO₄ pa60 ° C. Hapana "saizi-inokodzera-zvese" coating. Mamepu ega ega akananga kune chaiyo saiti chemistry-kwete lab fungidziro.
Kuita Kwechokwadi Kwenyika Inoda Kupfuura Rust Resistance
Corrosion resistance chete inoreva zvishoma kana fan isingakwanise kuchengetedza kuita. Takaongorora kumimisheni kwemugero uko mafeni akapasa bvunzo dzemunyu-spray asi akatadza kusimbiswa-nekuti vibration yakakwira pa72 Hz nekuda kwekusagadzikana kwetitanium blades, kana nekuda kwekupisa kwekuwedzera kusapindirana kwakatsemuka epoxy zvisimbiso panguva yemazuva ese 40°C bhasikoro. Zibo Hongcheng inogadzirisa idzi nzira dzakavanzika dzekutadza:
- Dynamic kuenzanisa kune ISO 1940 G2.5-kwete G6.3-yakasimbiswa pasi pemutoro, kwete isina basa
- Thermal kuwedzera muripo mumafuremu anokwirisa, uchishandisa bimetallic shim kumatanho anotenderera -20°C kusvika +65°C
- Seal geometry yakasimbiswa kupesana ne10⁵ kutenderera kutenderera (kufananidza makore makumi maviri ekunyorovesa actuation)
- Mota insulation yakaiswa F-kirasi (155°C), ine conformal coating pa windings for humidity ingress resistance
FBD yavo yakatevedzana tunnel mafeni anoenderera mberi-basa pa4,500 Pa static pressure uye 120,000 m³/h kuyerera-pasina kudzoreredza corrosion margin. Imhaka yekuti corrosion control yakadzikwa mumakanika dhizaini, isina kuvharirwa sekufunga kwekupedzisira.
Kugadzirisa Zvinoenderana Nechokwadi Saiti-Kwete Catalog Sheets
“Isingadziviriki” zvinoreva zvinhu zvakasiyana mumugodhi wemarasha maringe nemugero we subway maringe nemugero wekuchenesa mvura. Vamwe vatengesi vanopa matatu ekupfekedza sarudzo uye voidaidza kuti kugadzirisa. Zibo Hongcheng inobata chirongwa chega chega sedambudziko reinjiniya yemidziyo. Vanokumbira saiti-chaiyo data: pH yemasamples econdensate, SO₂ matanda evasungwa, chloride ion ppm mumvura yekuwachisa, kunyangwe mwaka wedova point curves. Ipapo vanosarudza—kwete kurayira.
Semuyenzaniso: mugero uri padyo nechiteshi cheQingdao waida kuramba kuNaCl aerosol *uye* kushatiswa kweUV kubva muzvikamu zvemasikati. Standard epoxy yero uye chipped. Mhinduro yavo? Fluoropolymer topcoat pamusoro pezinc-rich primer, yakaiswa nerobhoti yekupfapfaidza misoro ye ± 5 μm ukobvu kutonga. Nguva yekuendesa: 6 mavhiki-kwete 12. Hapana kukanganisa pane chitupa: ese mayuniti anotakura CE, CCC, uye ATEX Zone 1/21 mamaki painodiwa. Tsika hazvirevi kunonoka. Zvinoreva kukodzera-kune-chinangwa, kunosimbiswa kusati kwatumirwa.
Kukosha Kwenguva Yakareba Kunotanga Nekuiswa-uye Kunoenderera Mushure meKutuma
Mugero usingadziviriri wetunnel fan inodzorera mugore rechitatu-kwete gore rokutanga. Iyo ROI inobuda mukudzivirirwa nguva yekudzivirirwa: hapana kuvharwa kusingarondedzerwe kweblade kutsiva, hapana kukurumidza mota inodzoreredza nekuda kwekunyorova ingress, hapana kusimbiswa kwemaitiro ekukwira mabhureki. Asi kukosha kunoenderana nekutumirwa kwakarurama. Zibo Hongcheng inopa kits yekumisikidza yakanamirwa kune tunnel geometry-kwete generic hardware mapakeji. Mainjiniya avo anosimbisa anchor torque specs inopesana neiyo substrate density (kongiri giredhi, shotcrete bond simba), gadzirisa inlet cone angles kune aripo duct turbulence profiles, uye simbisa vibration yekuzviparadzanisa mounts kune resonant frequencies pazasi 12 Hz.
Kumashure-kumisikidzwa, ivo vanoteedzera mashandiro kuburikidza nesarudzo IoT sensors-yekutarisa inotakura tembiricha delta, maharmonics azvino, uye kutenderera kwemhepo kunopesana nekutanga. Kana data richiratidza kudonha kwe 3.2% kushanda zvakanaka kwemwedzi mitanhatu, timu yavo inoongorora kuti iri kushatisa, diki corrosion kutanga, kana dhiraivha bhandi rekutyaira- risati ratadza. Iyi haisi sevhisi. Iko kuenderera mberi kwekushanda kwakagadzirwa mukati.
Kune tunnel uko kufefetera kusiri nyore - ndiko kuchengetedza kwehupenyu - a Kuora-resistant tunnel fan inofanira kuwana zita rayo zuva nezuva. Kwete murabhoritari. Kwete pabepa. Mune yakanyorova, makemikari anoshanda, vibration-inowanzoitika yepasi pevhu. Zibo Hongcheng Fan Co., Ltd. inovaka vateveri vanopasa bvunzo iyoyo-kwete kamwe chete, asi kwemakore gumi nemashanu. Nekuti kufefetera kusingaperi hakutangi nemafambiro emhepo. Zvinotanga nezvinhu zvinoramba kukanda mapfumo pasi.
