Marasha mugodhi guruva rekubvisa mafeni masisitimu haasi ekuwedzera ekuwedzera-ndiwo ekutanga kudzivirira kubva kuchirwere chekufema, njodzi yekuputika, uye nguva yekugadzira. Mukushanda kwepasirese kuShandong, Shanxi, uye Inner Mongolia, takaona kutadza kwemhepo kunokonzeresa kumira kusingarongerwe mukati memaawa makumi manomwe nemaviri. Kuunganidzwa kweguruva pamota windings? Yakasimbiswa mumatatu akapatsanurwa kumeso kwemarasha gore rapfuura. Kusawirirana kweFan mushure memwedzi mitanhatu yekuenderera mberi nekushanda? Nyaya inodzokororwa-kusvikira vashandisi vachinja kune chinangwa-chakavakwa, chine simba chakaringana mayuniti ane akasanganiswa eguruva-akavharwa mabhengi.
Sei Mafeni Majairwa Achitadza Pasi pevhu
A general-chinangwa axial fan inofambisa mweya. A Coal mine guruva kubvisa fan inofambisa mhepo *ichiri kurarama* abrasive particulate, humidity yakakwirira, methane-laden atmospheres, uye kushanduka kwevoltige kunowanzoitika mumagridi ekumigodhi ari kure. Kukundikana kwakawanda kunodzokera kumashure matatu ekufungidzira asina kuenderana:
- Fungidziro #1: "Dust igrit inofambiswa nemhepo." Chokwadi: Guruva remarasha rinotakura static charge, rinonamira nemagetsi kune impeller surface, uye rinobvisa mashizha ealuminium pa 0.08 mm/gore pasi pemutoro unoramba uripo.
- Fungidziro #2: "Kuputika-chiratidzo = kushivirira guruva." Chokwadi: Imba yemotokari yakasimbiswa yeEx-d inodzivirira kupisa-asi haimise guruva kuti isavhare zvimbi zvinotonhodza, ichikwidza tembiricha inomonereka ne22°C pamusoro peyakayerwa.
- Fungidziro #3: "Yakakwirira CFM inogara ichireva kutonga kuri nani." Chokwadi: Mhepo ine bongozozo, isina mhepo inotenderera inotenderedza huruva pachinzvimbo chekuibata kwairi. Kubvisa kunoshanda kunoda velocity profiles inofananidzwa nehood dhizaini-kwete mbishi kubuda.
Isu takayera izvi toga mune 2023 retrofit pane Datong yepasi pevhu longwall panel. Kutsiva 30 kW yakasanganiswa-kuyerera unit neFBD yakatevedzana (dⅠ) inotenderedza axial feni yakacheka inofemurika guruva kuratidzwa ne 64% - kwete nekuti yaifambisa mweya wakawanda, asi nekuti iyo mbiri-nhanho yekumanikidza curve yakachengetwa > 18 m/s yekubata velocity pakuscrubber inlet, kunyangwe sekuramba kwesefa kwakakwira.
Zvina Zvisingataurwi Zvekugadzira Zvinodiwa
Kutsanangura a Coal mine guruva kubvisa fan zvinoreva kuisa pamberi peinjiniya-yakapupurirwa mumunda pamusoro pekatalogi specs. Hezvino izvo zvinobata pasi pevhu:
- Dust-sealed dynamic balancing: Rotor yakaenzana kusvika kuG2.5 giredhi * mushure me* yakazara kusangana-kusanganisira guruva nhoo uye shaft couplings-kwete chete mapeller asina chinhu. Unbalanced vibration inomhanyisa kutakura kupfeka ne 3.7 × munzvimbo dzine guruva.
- Kuumbwa kwezvimiro zvinodzivirira Corrosion: Dzimba dzakagadzirwa nesimbi dzinokundikana uko H₂S inosangana ne condensation. Titanium mafeni anotsungirira acid gasi kuratidzwa; yakavharwa kabhoni simbi ine ISO 12944 C5-M chiyero chinotora 3 × kureba kupfuura yakajairwa pendi mumasumps akanyorova.
- Kuputika-uchapupu kutendeseka pasi pekunetseka kwekupisa: Mota dzinofanirwa kuchengetedza Ex-d certification iri pa110°C ambient—inowanikwa pedyo nemadhiraivha. Izvo zvinoda Kirasi H insulation *uye* asiri-ferrous terminal mabhokisi kudzivirira spark kupararira kuburikidza nekukwira mabhaudhi.
- Kugadziriswa kwesevhisi: Hapana disassembly inodiwa kutakura kutsiva. Vanamazvikokota vepasaiti muXuzhou vakasimbisa kuti vakatsiva maviri-mutsara spherical roller mabheji pa9-19 centrifugal blower mumaminetsi makumi mana nemanomwe - vachishandisa zvipanera zviviri chete uye pasina crane.
Real Deployment Data: Chii Chinoshanda Kupi
Iko hakuna mhinduro yepasirese. Chikumbiro chinoraira dhizaini:
- Misoro yebudiriro: FBD yakatevedzana inopokana-inotenderera axial mafeni inoburitsa 12–28 kPa static kumanikidza-yakakwana kusunda mweya kuburikidza ne500+ metres yekudhonza uku uchichengetedza kumhanyisa kwechiso. Mamiriro avo maviri-motor anobvisa kutsvedza kwebhandi uye anobvumira kutanga kwatangwa kudzivirira kukwira kwegridi.
- Coal bunker & mapoinzi ekutamisa: Anti-corrosion centrifugal mafeni ane mablades akachinjika kumashure anobata 350–450 g/m³ kurodha huruva pasina kudonha kwekuita. Takaedza imwe unit nguva dzose kwemwedzi gumi nemina paYanzhou wash chirimwa-kushanda kwakachengetwa mukati me ± 1.3% kunyangwe mazuva ese abrasive ekuchenesa kutenderera.
- Underground substations: Kuputika-kupikisa titanium mafeni anomhanya akanyarara pa72 dBA-kunyangwe pakazara. Kuvaka kwavo kusiri kwemagineti kunobvisa eddy ikozvino kudziyisa padyo nepamusoro-voltage switchgear.
Power draw nyaya. Inoshandiswa zvisirizvo 45 kW fan inomhanya 24/7 inodhura $18,700/gore mumagetsi chete (pa $0.08/kWh). Kodzero Coal mine guruva kubvisa fan-yakagadzirirwa kupikisa kwehurongwa, kwete peak kubuda-inocheka iyo ne22-31% pasina kupa chibayiro chekubata kubata.
Kusarudza Mumwe Wako, Kwete Chete Chigadzirwa
Iwe unoda application engineering-kwete kabhuku kePDF. Kana mutengi weHeilongjiang akataura akadzokororwa kutsemuka kwemhepo mumatairi avo ekubvisa sulfurization, timu yedu yakatumira injinjiniya yemunda ine inotakurika vibrometer uye particle counter. Root cause? Resonance pa1,740 RPM inopindirana neiyo boiler pulsation frequency. Mhinduro: Yakagadziridzwa blade kuverenga uye yakasimbiswa hub-inounzwa mumazuva gumi nerimwe.
Zibo Hongcheng Fan Co., Ltd. inovaka zvese Coal mine guruva kubvisa fan mukati-mumba-kubva kune chaiyo-yakagadzirwa titanium impellers kusvika kuputika-proof motor windings-pasi pe ISO 9001-yakarongeka yekuongorora mapuroteni. Imwe neimwe unit inopinda 48-awa yekuyedzwa kwemutoro nekuyedzerwa kurodha huruva isati yatumirwa. Hapana offshore subcontracting. Hapana "standard" zvibvumirano.
Hunhu hwemhepo pasi pevhu hausi hwekutevedzera - ndezvekuenderera mberi. Ndiwo mutsauko pakati pekuchinja kunomhanya kwakachena uye imwe yakamiswa neguruva-yakakonzeresa methane alarm. Sarudza feni yakagadzirirwa chokwadi chemugodhi-kwete vimbiso yebhurocha.
