Ukukhetha okulungileyo Iindidi ze-centrifol fan ayithethi malunga nokuthelekisa inombolo yekhathalogu kwi-nameplate. Kumalunga nokusombulula ingxaki yokwenene-ukuhambisa umoya ngokuchasene nokuchasana, ukuphatha imisi etshabalalisayo, ukusinda kwi-200 ° C kwimijelo yokukhupha, okanye ukugcina umgodi wamalahle ungenisa umoya phantsi kweemeko ezinobungozi bokuqhuma. Silinganise, savavanya, kwaye sagunyazisa ngaphezu kwe-1,200 yabalandeli be-centrifugal ukusukela ngo-2020-kwaye kuzo zonke iimeko, uhlobo olungalunganga lubangele ulibaziseko, ukuyekelela kukhuseleko, okanye ukusilela kwangaphambi kwexesha.
Kutheni "Uhlobo" lubaluleke ngaphezu kobukhulu okanye isantya
I-9-19 high-pressure centrifugal blower ihambisa umoya ngokwahlukileyo kune-double-inlet centrifugal fan-kwanakwi-RPM efanayo kunye noxinzelelo lwe-static. Umahluko ulele kwijiyometri ye-impeller, uyilo lwe-casing, kunye nendlela yokuhamba komoya. I-impellers ezigobile ngasemva zibamba igesi egcwele uthuli ngaphandle kokuvala. Iiyunithi ezigobileyo ezihamba phambili zihambisa umthamo ophezulu kuxinzelelo oluphantsi lwe-static-kodwa zisilela ngokukhawuleza kwiindawo ezinqabileyo. Ii-radial-tip impellers zihlala phakathi kwazo: ukusebenza kakuhle okuphakathi, ukunyamezelana okuphakamileyo kwe-particulates, kunye nokulula koomatshini okubalulekileyo ngexesha lokugcinwa kwiindawo ezikude.
Sakhe satshintsha i-fan engaphumeleliyo egobileyo kumgca wokudaya welaphu kunye nemodeli ejonge ngasemva. Iyunithi yokuqala yahlala iinyanga ezi-4. Eli litsha liqhube iinyanga ezingama-37-akukho nto itshintshileyo, akukho kutyibilika kwebhanti, akukho kwehla komoya. Ngoba? Kuba isicelo sifuna isiphithiphithi esiphantsi, hayi ubukhulu beCFM. Lo ngumgaqo wokuqala: fanisa uhlobo kwi indlela yokuziphatha yomoya, ingeyiyo nje itshathi yokuhambisa.
Iindidi ezine zeFan ezingundoqo ze-Centrifugal-kwaye apho zisilela khona
Abasebenzisi bemizi-mveliso abafuni iindidi zemfundo. Bafuna ingqiqo yesigqibo. Nantsi into esebenzayo-kwaye apho uhlobo ngalunye luqhekeka khona:
- Ngasemva-gophe (BC) abalandeli: Eyona ingcono kwi-high-static, ubushushu obuphezulu, okanye inkonzo edlekayo-njengezipaki ze-desulfurization okanye kwibhoyila yomoya wokuqala. I-Impeller blades igophe kude nokujikeleza. Ukusebenza kakuhle kuphezulu kwi-82-87%. Kodwa bafuna ulungelelwaniso oluchanekileyo lokungena; i-ductwork engalunganga ibangela ukungcangcazela okuqhekeza izindlu. Iimodeli zethu ze-BC (umzekelo, i-anti-corrosion variants kunye ne-FRP-coated casings) iquka i-laser-aligned inlet cones njengomgangatho.
- Phambili-gophe (FC) abalandeli: I-compact, izolile, kunye nevolumu ephezulu ekuchaseni okuphantsi-ilungele i-HVAC yokwenza umoya okanye ukujikeleza kwakhona kwegumbi. Kodwa bame ngokulula ngasentla 150 Pa uxinzelelo static. Siye sabona iiyunithi ezintathu zeFC zisilela kwimigca yokubuyisela isityalo sekhemikhali ngenxa yokuba abaqhubi abawuhoyanga umnqantsa wokunyuka koxinzelelo. Azenzelwanga ukuchasana okuguquguqukayo.
- I-Radial-tip (RT) abalandeli: Amahashe omsebenzi anothuli, afumileyo, okanye arhabaxa kancinci—ukungenisa umoya wasemigodini, ukupholisa isiseko, umbhobho weonti ejikelezayo. Iiblades zinwebeka ngokuthe ngqo, zixhathisa ukwakhiwa. Ukusebenza kwencopho ephantsi (72-78%) kurhweba ngayo ukuthembeka. Kwisicelo esipholileyo somxumi we-metallurgical, abalandeli be-RT banqumle ixesha lokuphumla elingacwangciswanga ngama-63% ngokuchasene nezinye iindlela ze-BC.
- Iifeni ze-centrifugal ezifakwe kabini: Ii-impellers ezimbini kwishaft enye, zitsala umoya macala omabini. Ihambisa ukuhamba okulinganayo ngaphandle kwe-asymmetry ye-duct. Kubaluleke kakhulu apho isithuba sixineneyo kodwa umoya kufuneka uhlale uzinzile—njengamasango okuvula itonela okanye iinkqubo zokukhupha umsi ezixhonywe eluphahleni. Nangona kunjalo, zifuna ukunyuswa kwesiseko esiqinileyo. Ukutshintsha kwesiseko se-2 mm kubangele ukuvakala kwiprojekthi yakutsha nje de songeze iipads ezikwaziyo ukucheba.
Yintoni iKhathalogu engayi kukuxelela yona
Abanye banokuxoxa ukuba ukhetho lwezinto eziphathekayo luxinanisa uhlobo lwe-impeller. Kodwa siye sabona abalandeli be-titanium abanokumelana nokugqwesa okugqibeleleyo kusilela ngenxa yokuba i-impeller egobileyo engasemva ayikwazanga kuthwala uthuthu lwempukane. Uhlobo luchaza i-physics. Isixhobo sichaza ifestile yokusinda.
Iinyaniso ezintathu ezinzima ezivela kwidatha yasendle:
- Iigophe zoxinzelelo zixoka. Ifeni ekalelelwe i-“12 kPa @ 25,000 m³/h” ithatha iimeko ezifanelekileyo zokungena. Iingqiniba zemibhobho yokwenyani, izidambisi-manzi, kunye nezihluzi zehlisa ukusebenza kokwenyani nge-12–18%. Hlala uvavanya kwinqanaba lenkqubo-hayi nje abalandeli kuphela.
- Isiqinisekiso sokuthintela uqhushumbo (umzekelo, dⅠ semigodi yamalahle) sisebenza kwindibano epheleleyo—kungekhona injini kuphela. Imoto eqinisekisiweyo efakwe kwibhawudi yokuthotyelwa kwezindlu ezingaqinisekisiweyo. Ukudityaniswa kwethu kothotho lwe-FBD kubandakanya ukukhutshwa kwe-spark-resistant impeller kunye neendlela ezisekelwe kwi-static eziqinisekisiweyo nge-GB 3836.1 nganye.
- Ulungelelwaniso olunamandla alukhethi. Abalandeli be-BC abangalungelelananga bangcangcazela kwi-1,450 RPM. Kwi-2,900 RPM, ukungalingani okufanayo kuphinda-phinda amandla kane. Wonke umlandeli we-centrifugal waseHongcheng ufumana i-ISO 1940 G2.5 ukulinganisa-kulinganiswa, akucingelwanga.
Indlela Yokukhetha—Uludwe Lokutshekisha Lwemizuzu emihlanu
Ngaphambi kokuba uvule iphepha elithile, phendula le mibuzo mihlanu:
- Yintoni na Uxinzelelo oluphezulu oluzinzileyo-hayi incopho, hayi ithiyori? Ukulinganisa nge-manometer kwi-fan inlet, phantsi komthwalo opheleleyo.
- Ngaba umsinga womoya uqulathe abrasives, ukufuma, okanye imichiza? Ukuba ewe, susa igophe elingaphambili. Beka phambili i-radial-tip okanye i-backward-curved kunye neengubo ezikhuselayo.
- Ngaba indawo encinci? I-inlet ephindwe kabini igcina unyawo kodwa ifuna ubungqongqo besakhiwo. Indawo yokungena enye enekhowuni yokungena eyandisiweyo inokuba lula.
- Ngaba abaqhubi baya kulungelelanisa ukuhamba rhoqo? Ngasemva-gophe izibambo ukutswina ngcono. Ukuqhubela phambili-gophe ngokungalindelekanga ngaphantsi kwe-60% yesantya.
- Yintoni na iindleko zokusilela? Ukuvalwa kwindlu yebhoyila kubiza i-$ 18,000 ngeyure. Hlawula ngaphambili kwi-backward-curved + edityanisiweyo yokujongwa kwe-thermal-kungekhona kamva ukulungiswa okungxamisekileyo.
Iintlobo zeefeni ze-Centrifugal aziyonxalenye etshintshanayo. Ziyimpendulo yobuchule kwimiqobo yomzimba. Khetha uhlobo oluwuhlonelayo umoya wakho, indawo okuyo, kunye nexesha ojolise kulo—hayi eyona ncwadana iqaqambileyo.
