Iinkqubo zokususa uthuli lomgodi wamalahle azikho ezongezelelweyo-zilukhuselo lwangaphambili ngokuchasene nesifo sokuphefumla, umngcipheko wokudubula, kunye nexesha lokunciphisa imveliso. Kwimisebenzi yehlabathi yokwenyani kulo lonke elaseShandong, eShanxi, nakwiMongolia yaNgaphakathi, sikubonile ukusilela komoya okubangela ukumiswa okungacwangciswanga kwiiyure ezingama-72. Ukuqokelelana kothuli kwiimotor windings? Kuqinisekiswe kwiindawo ezintathu ezahlukeneyo zokujongana namalahle kunyaka ophelileyo. Ukungalingani kwabalandeli emva kweenyanga ezintandathu zokusebenza rhoqo? Umcimbi ophindaphindiweyo-de kube abaqhubi batshintshela kwiiyunithi ezakhiweyo, ezilungelelanisiweyo ezinokulinganisela kunye neebheringi ezidityanisiweyo zothuli.
Kutheni amaFani aMgangatho angaphumeleli phantsi komhlaba
I-axial fan yenjongo jikelele ihambisa umoya. A Cola uthuli lwam ihambisa umoya *ngelixa usinda* i-particulate egqabhukileyo, ukufuma okuphezulu, i-methane-laden atmospheres, kunye nokutshintshatshintsha kwamandla ombane okuqhelekileyo kwiigridi zemigodi ezikude. Uninzi lweentsilelo zibuyela emva kwiingqikelelo ezintathu ezingahambelaniyo:
- Ucingelo #1: “Uthuli luthuli nje olusemoyeni.” Inyani: Uthuli lwamalahle luthwala intlawulo engashukumiyo, luncamathela ngokwe-electrostatically kumphezulu we-impeller, kwaye lukhukulisa iincakuba ze-aluminiyam nge-0.08 mm/ngonyaka phantsi komthwalo oqhubekayo.
- Ucingelo #2: "Ubungqina bokudubula = ukunyamezela uthuli." Inyani: I-Ex-d certified motor housing inqanda ukuvutha-kodwa ayinqandi uthuli ekuvaleni amaphiko okupholisa, inyusa ubushushu obujikelezayo nge22°C ngaphezu komda obekiweyo.
- Ucingelo #3: "I-CFM ephezulu ihlala ithetha ulawulo olungcono." Inyani: Ukuhamba komoya okusiphithizelayo, okungaguquguqukiyo kujikelezisa uthuli endaweni yokuluthatha kumthombo. Ukususwa okusebenzayo kufuna iiprofayili zesantya ezihambelana noyilo lwe-hood-hayi imveliso ekrwada.
Silinganise oku ngokobuqu kwi-2023 retrofit kwi-Datong phantsi komhlaba longwall panel. Ukutshintsha i-30 kW yeyunithi yokuqukuqela okuxutyiweyo ngothotho lwe-FBD (dⅠ) i-axial fan ejikelezayo inqumle ukutyhileka kothuli oluphefumlayo ngama-64%—kungekhona ngenxa yokuba ihambisa umoya omninzi, kodwa ngenxa yokuba igophe layo loxinzelelo olukwizigaba ezibini ligcine i->18 m/s isantya sokubanjwa kwi-scrubber inlet, nanjengoko uxhathiso lwesihluzi lunyukile.
IiMfuno ezine zoYilo eziNgaxoxisiyo
Ukuchaza a Cola uthuli lwam kuthetha ukubeka phambili ubunjineli obungqiniweyo kwinkalo yeenkcukacha zekhathalogu. Nantsi into ebambe phantsi komhlaba:
- Ukulinganisa okuguquguqukayo okuvalwe ngothuli: Ii-Rotors zilinganiswe kwi-G2.5 grade * emva * kwendibano epheleleyo-kubandakanywa izihlangu zothuli kunye nokudibanisa i-shaft-kungekhona nje i-impellers engenanto. I-vibration engalinganiyo ikhawuleza ukuthwala ukuthwala nge-3.7 × kwiindawo ezinothuli.
- Ulwakhiwo oluxhathisayo kukonakala: Izindlu zentsimbi ezenziwe ngesinyithi ziyasilela apho i-H₂S idibana ne-condensation. Iifeni ze-Titanium zimelana nokuvezwa kwegesi ye-asidi; i-carbon steel coated kunye ne-ISO 12944 C5-M yokulinganisa ihlala i-3 × ixesha elide kunepeyinti eqhelekileyo kwiisumpu ezimanzi.
- Ingqibelelo yobungqina bokuqhuma phantsi koxinzelelo lwe-thermal: IiMoto kufuneka zigcine isiqinisekiso se-Ex-d kwi-110 ° C ambient-eqhelekileyo kufuphi ne-conveyor drives. Oko kufuna ukugqunywa koHlelo H *kunye* neebhokisi zeterminal ezingezizo i-ferrous ukuthintela ukwanda kwentlantsi ngeebholiti ezinyukayo.
- Ulungiso olufikelelekayo kwinkonzo: Akukho disassembly efunekayo ukuthwala indawo. Amagcisa akwisiza e-Xuzhou aqinisekisile ukuba atshintshe iibheringi ezingqukuva ezimbini kwi-9-19 centrifugal blower kwimizuzu engama-47-besebenzisa iziklintshi ezibini kuphela kwaye akukho crane.
Idatha yokusasazwa yokwenyani: Yintoni esebenza phi
Akukho sisombululo sijikelezileyo. Isicelo siyalela uyilo:
- Izihloko zophuhliso: I-FBD series counter-rotating axial fans ihambisa i-12-28 kPa static pressure-eyanele ukutyhala umoya ngeemitha ezingama-500+ ze-ducting ngelixa ugcina isantya sobuso. Uyilo lwazo lweemoto ezimbini lususa ukutyibilika kwebhanti kwaye luvumela ukuqaliswa okucwangcisiweyo ukunqanda ukunyuka kwegridi.
- Indawo yokuhlala yamalahle kunye neendawo zokutshintshela: Iifeni ze-anti-corrosion centrifugal ezinencakuba ezigobile ngasemva zibamba i-350–450 g/m³ ukulayisha uthuli ngaphandle kokuwa komsebenzi. Sivavanye iyunithi enye ngokuqhubekayo kwiinyanga ze-14 kwisityalo sokuhlamba saseYanzhou-ukusebenza okugcinwe ngaphakathi kwe-± 1.3% nangona imijikelezo yokucoca i-abrasive yemihla ngemihla.
- Izitishi ezingaphantsi komhlaba: Abalandeli be-titanium-ubungqina bokuqhuma baqhuba cwaka kwi-72 dBA-nokuba bathwele ngokupheleleyo. Ulwakhiwo lwabo olungeyo-magnetic luphelisa ukufudumeza kwangoku kwe-eddy kufuphi ne-high-voltage switchgear.
Amandla atsala imicimbi. I-45 kW fan engafanelekanga eqhuba i-24/7 ixabisa i-$ 18,700 / ngonyaka kumbane wodwa (nge-$ 0.08 / kWh). Ilungelo Cola uthuli lwam-elungiselelwe ukuchasana kwenkqubo, kungekhona i-peak output-cuts that by 22-31% ngaphandle kokuncama ukusebenza kakuhle kokubamba.
Ukukhetha iqabane lakho, hayi iMveliso nje
Udinga ubunjineli besicelo-hayi ikhathalogu yePDF. Xa umxhasi we-Heilongjiang echaza ngokuphindaphindiweyo i-impeller yokuqhekeka kwimibhobho ye-desulfurization, iqela lethu lathumela injineli yentsimi kunye ne-vibrometer ephathekayo kunye ne-particle counter. Unobangela weengcambu? I-resonance kwi-1,740 RPM ehambelana ne-boiler pulsation frequency. Isisombululo: Ubalo lweblade olulungelelanisiweyo kunye nehabhu eyomeleziweyo-zinikezelwe kwiintsuku ze-11.
Zibo Hongcheng Fan Co., Ltd. yakha yonke Cola uthuli lwam endlwini-ukusuka kwi-impellers ye-titanium echanekileyo-oomatshini ukuya kwii-motor-proof windings-phantsi kweeprothokholi zokuhlola ezihambelana ne-ISO 9001. Iyunithi nganye ivavanywa ngomthwalo weeyure ezingama-48 ngothuli olufanisiweyo lokulayisha phambi kokuthunyelwa. Akukho ikontraki engaphantsi elunxwemeni. Akukho "standard" compromises.
Umgangatho womoya ophantsi komhlaba awukho malunga nokuthotyelwa-kungokuqhubeka. Ngumahluko phakathi kweshifti ebaleka icocekile kwaye enye inqunyanyiswe yi-alarm ye-methane ebangelwe luthuli. Khetha fan eyenzelwe ubunyani bomgodi-hayi isithembiso sencwadana.
