Metal mine ventilator masisitimu haingori midziyo-ndiyo mutsara wekutanga wekudzivirira kubva pakudzipwa, kuputika, uye kushushikana kwekupisa. Mukushanda kwepasirese, takaona kutadza kwemhepo kunokonzeresa kuburitswa kwechimbichimbi-kwete nekuti mafeni akaparara, asi nekuti ivo vaive vasingatarisirwe kuunganidzwa kwemethane, kurodha guruva, kana kukasira kudzvanywa. Chiitiko cha2023 mumugodhi weShandong nonferrous chakazvisimbisa: yekutanga axial fan yakasangana nemhepo yekuyerera kwemhepo pabepa asi haina kukwanisa kusimudzira static pressure pamusoro pe1,800 Pa apo kusamira kwesefa kwakawedzera ne40% mushure memaawa makumi manomwe nemaviri ekushanda. Ndipo apo kuvimbika kunomira kuva dzidziso.
Nei "Kungori Kuyerera Kwemhepo" Kufungidzira Kune Njodzi
Migodhi yesimbi yepasi pevhu inoda kudarika volumetric kubuda. Vanoda mhinduro ine simba, kurongeka kwechimiro pasi pekudengenyeka, uye kutadza-kuchengetedza maitiro mumhepo inoputika. Iyo FBD yakatevedzana (dⅠ) inoputika-inoratidza kudzvanywa-jekiseni inopoterera-inotenderera axial kuyerera yemuno mhepo-inoshandiswa mumigodhi inopfuura makumi matatu nenomwe yakaoma-dombo mhiri kweChina neSoutheast Asia-yakagadzirwa chaizvo kuvhara iro gwanza. Yayo mbiri-motor, inopoterera-inotenderera dhizaini inopa 22-28% yakakwira kudzvanywa kushanda pane imwe-nhanho axial mauniti pane akafanana simba ekuisa. Zvakatonyanya kukosha, Kirasi I, Chikamu 1 chekuputika-chiratidziro hachina kuvharirwa pa-yakavakirwa mukati memotor imba geometry, shaft yekuisa chisimbiso interface, uye spark-inodzivirira impeller maitiro.
Asi kuita hakusi kungotaura chete. Zviri pamusoro pezvinoitika kana ambient tembiricha ikarova 52°C, hunyoro hwehama hunokwira pamusoro pe95%, uye silica dust concentration inodarika 8 mg/m³. Standard fan bearings vanobata. Bhandi rinofambisa slip. Motor windings inoderedza. Ndosaka kusarudzwa kwesimbi yemugodhi wemhepo kunofanirwa kutanga nemepu yezvakatipoteredza-kwete kubhurawuza kwekabhuku. Isu takaona vatengi vachicheka nguva yekutumwa ne60% pavakagovana mishumo yekuongorora gasi remuborehole uye marongero emazuva ese ekutakurwa kwematombo vasati vapedza kusarudzwa kwefani. Data chaiyo inokunda fungidziro dzenguva dzese.
Zvitatu Zvisiri-Negotiables muMetal Mine Ventilation Dhizaini
- Kuputika-uchapupu kutendeseka kunofanira kuwedzera kupfuura mota. Mafeni akatemerwa nzvimbo dzeZone 1 achiri kutadza kana inlet ductwork ikashaya kuenderera mberi kana kana silencer iine zvibatiso zvisina kudzivirirwa. Iyo FBD nhevedzano inosanganisa yakasimbiswa tambo dzepasi dzakananga mune inokwirisa flange-hapana munda retrofitting inodiwa.
- Kubata guruva hakusi kwesarudzo-inowedzera. Fani inoburitsa zviuru gumi nezviviri m³/h pakutanga inodonha kusvika pa9,300 m³/h mushure memazuva gumi nemana pasina gadziriso kana kusefa kwemukati kusina kukwana. Titanium mafeni-yakagadzirirwa nzvimbo dzepamusoro-soro, nzvimbo dzepamusoro-dzinochengetedza> 94% yemhepo yakatemerwa kuyerera kwemazuva makumi matatu pasina kuchenesa.
- Kudzora kupindura kunobata pasi pevhu. Variable frequency drives (VFDs) inofanirwa kuita mukati memasekonzi 1.2 kune CO sensor inokonzeresa. Mauniti ane analog-chete control loops anowedzera 4-7 masekonzi e latency-nguva yakakwana yekuti methane concentration iyambuka 5% LEL pachikumbaridzo munzvimbo dzakavharirwa.
Kana Kusiri-paSherufu Kusina Kuchengetedzeka Zvakakwana
Vamwe vanogona kukakavara kuti mafeni akajairwa maindasitiri anoshanda zvakanaka neakawedzera kuchengetedza zvinhu. Nekudaro, kuwedzera ekunze-kuputika-uchapupu akavharirwa kune yakajairika-chinangwa axial fan inogadzira emafuta mabhodhoro, inoderedza kuwana sevhisi, uye voids yepakutanga michina zvitupa. Zvakatonyanya, inounza mapoinzi matsva ekukundikana: gasket compression kurasikirwa, conduit seal degradation, uye vibration-induced wiring kuneta. Kugadziridza hakusi kweumbozha- ndezvekubvisa nzvimbo dzinosangana nenjodzi.
Zibo Hongcheng Fan Co., Ltd. inovaka musimboti uyu mukufamba kwayo. Kana mugodhi wemhangura muYunnan waida feni inokwanisa 3,200 Pa static pressure pa8,500 m³/h ichishanda ichienderera pa75°C tembiricha yekupedza simba, mainjiniya haana kushandura modhi iripo. Ivo vakamhanyisazve blade twist profiles muANSYS CFX, yakasarudzwa Inconel 625 yemarotor hubs, uye yakasimbisa kushivirira kwekuwedzera kwemafuta mukati me120-awa yekupisa-mubvunzo. Zvakaguma nei? Chikamu chakanyoreswa kuGB 3836.1–2021 uye ISO 8573–1 Kirasi 2 yekusvibiswa-inounzwa mumavhiki gumi nerimwe, kwete mwedzi mitanhatu.
Chii Chinouya Mushure meInvoice Chinonyanya Kukosha
A metal mine ventilator haiwani kukosha kwayo panguva yekuisa-inozviratidza panguva yekuchinja kwechitatu kwevhiki 17. Ndiyo apo vibration harmonics inoratidza kusaruramisa, apo kutakura maitiro ekushisa kunofumura kusawirirana kwelubrication, uye apo kutonga kwepfungwa kunofumura firmware bugs. Zibo Hongcheng Fan Co., Ltd. inosanganisira kure kure kuongororwa kugadzirira mune ese FBD uye titanium-akatevedzana mayunitsi: Modbus TCP rutsigiro, onboard tembiricha/kudzvanywa/vibration sensors, uye firmware-inosimudzira logic controllers. Nyanzvi dzemumunda hadzimirire kuputsika-vanoona kutsauka pa3% amplitude kuwedzera, kwete 30%.
Sevhisi haisi kushanda. Zviri kufanotaura. Chikwata chavo cheinjiniya chekushandisa chinoongorora zvigadziriso zvemugodhi wemhepo isati yaendeswa - kwete kukwidza, asi mureza kureba kwemadhaivhi, kusagadzikana kunokonzerwa nemagokora, kana kukwirisa-kwakavakirwa density magadziriso ayo anoshandura mabhureki ebhiza anodiwa anosvika gumi nerimwe%. Iko kutarisisa kunodzivirira kudhura kwemunda kudzoreredzwa uye kuchengetedza nzira dzemhepo dzichienderana neChina's AQ 2013-2018 kuchengetedza zviyero.
Chengetedzo-yakakosha ventilation haina nzvimbo yekukanganisa. Yese yesimbi mugodhi mhepo inofanirwa kupindura mibvunzo mitatu isati yatumirwa: Inopona nharaunda here? Inopindura zviratidzo zvekutyisidzira nekukurumidza kupfuura nguva yekuita kwevanhu? Inotsigira here ecosystem inofungidzira nzira dzekukundikana - kwete kungozvinyora? Zibo Hongcheng Fan Co., Ltd. inopindura hongu-kwete sezvikumbiro zvekushambadzira, asi semishumo yebvunzo, matanda emumunda, uye yechitatu-bato rekodhi rekodhi. Nekuti pasi pevhu, kuyerera kwemhepo hakuyerwe mumacubic metres paminiti. Inoyerwa muhupenyu hunotsigirwa, shanduko dzinopedzwa, uye njodzi dzinodzivirirwa.
