Ukusebenza kwabalandeli bokucima umlilo akulinganiswa ngeedecibels okanye i-airflow curves yodwa-ilinganiswa ngemizuzwana egciniweyo, ukubonakala kubuyiselwe, kwaye ubomi bukhuselwe. Xa umsi uminxa izinyuko, uzalise itonela, okanye ugqume ngengubo kwigumbi lokulawula imichiza, umoya oqhelekileyo awusebenzi. Into esebenzayo yinjongo eyakhelweyo Firefiriefirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifieri: ivolumu ephezulu, ukuthunyelwa ngokukhawuleza, yenzelwe isiphithiphithi-kungekhona intuthuzelo.
Kutheni “ukususwa koMsi oKhawulezayo” Kufuna Ngakumbi kune-CFM nje
Siye sayibona kwindawo: abasebenzi abakhupha i-30-meter ducts kuphela ukufumana i-15,000 yabo ye-CFM fan igxina kwi-40% yemveliso ngenxa yokuba i-backpressure spiked kufuphi nomnyango womlilo. Umoya wokucima umlilo wokwenyani wehlabathi awuphumeleli kwii-specs ezisezantsi-kodwa kuyilo olungahambelaniyo. Yinyani Firefiriefirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifieri kufuneka uhambise izinto ezintathu ngaxeshanye: uxinzelelo oluphezulu lwe-static (ukutyhala umoya kwimibhobho emide, enemibhobho); torque yangoko (akukho kulibaziseka kwenyuka xa amandla ebetha), kunye ukunyamezela kwe-thermal (ihlala ibaleka kuma-80°C ambient, hayi nje ama-40°C).
Uthotho lwe-FBD (dⅠ) lubonisa uqhushumbo oluchasene ne-axial flow fan-indawo evavanywe kwi-drills yokuhlangula imigodi yamalahle-ingqina oku. Idizayini yayo ye-motor-motor, ejikelezayo ejikelezayo yenza i-3,200 Pa yoxinzelelo oluzinzileyo ku-22,000 m³/h. Ayiyothiyori leyo. Kwi-2023 yokulinganisa umlilo we-tunnel e-Shandong, yacima i-90% yomsi obonakalayo ukusuka kwinqanaba leemitha ze-180 ngaphantsi kwemizuzwana ye-97-ngelixa igcina umoya ozinzile nangona i-spikes ye-inlet ye-inlet ukuya kwi-120 ° C. Iifeni ze-axial eziqhelekileyo ziminxe ku-65°C.
Yintoni eyenza umlandeli “uLungele iNdawo yoMlilo”—Hayi nje “iBanga loMzi-mveliso”
Abanye abavelisi babhala nayiphi na i-fan-duty-duty fan "njengeyokucima umlilo." Oko kukwenza lula okuyingozi. Ukungena komoya kwindawo yomlilo kufuna urhwebo oluphumelele nzima:
Isiqinisekiso sobungqina bokudubula asiyonto yokuzikhethela-akunakuxoxisana kwiindawo zomphunga otshayo. Umgangatho we-dⅠ ugubungela imeko-bume yothuli lwemethane/amalahle nge-GB 3836.1–2021, hayi nje ukuleyibhile “kukhuselekile” jikelele. Ubunzima ngokuchasene nokuhanjiswa: I-120-kg ye-centrifugal blower inokuhambisa umoya ngakumbi-kodwa ukuba abacimi-mlilo ababini abanako ukuyiphakamisa kwilori yeleli ngaphantsi kwe-45 imizuzwana, akunamsebenzi. Uninzi lobuthunywa-lubaluleke kakhulu Firefiriefirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifieri iiyunithi zihlala phantsi kwe-42 kg ngaphandle kokuncama ingqibelelo ye-impeller. Ujongano lweDuct lubaluleke ngaphezu kwamandla ehashe. Sitshintshe abalandeli ngeespecs ezifanayo kodwa ijometri yeflange eyahlukileyo-kwaye sinqumle ixesha lokuseta nge-60%. Ukudibanisa ngokukhawuleza, i-tapered, i-self-sealing couplings isusa ukuvuza okopha i-25-40% ye-airflow esebenzayo. Yiyo loo nto iZibo Hongcheng Fan Co., Ltd. Iimodeli zabo ze-FBD zihamba ngenqanawa kunye ne-ISO 5211-ehambelana neepleyiti zokuxhoma kunye neekhola ezisemgangathweni ze-630 mm. Akukho ziadaptha. Akukho kuphuculwa kwebala.
Ukwenza ngokwezifiso ayisiyonto yobumnandi-Ngumahluko phakathi "kweMisebenzi" kunye "noGcina"
I-"Off-the-shelf" ayifane ilingane nemiboniso yomlilo. Indawo yokucoca idinga ukuchasana nomhlwa ngokuchasene nomsi ogcwele i-H₂S. Indawo yokusila ifuna izixhobo ezikwaziyo ukumelana nentlantsi. Isikhululo sikaloliwe esihamba ngaphantsi komhlaba sifuna ukusebenza kwengxolo ephantsi kakhulu engaphantsi kwe-72 dB(A) kwiimitha ezi-3—ngaphandle kokunqumla umoya.
Omnye umxhasi-umcimi-mlilo kamasipala eJiangsu-wayefuna a Firefiriefirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifieri enokuthi iqhube ngokuqhubekayo iiyure ezi-4 kwi-100% yomthwalo ngelixa usinda ekukhuselekeni kwamanzi okuphindaphindiweyo. Izindlu ezisemgangathweni ze-IP54 aziphumelelanga kwimizuzu engama-90. Isicombululo? Izindlu ezilungiselelwe i-titanium-alloy (engagcwelenga i-titanium-indleko-zingavumelekanga), i-IP67-rated motor seals, kunye neziqhoboshi zentsimbi. Ithunyelwe ngeentsuku zokusebenza ezili-11. Ivavanywe kwimijikelo yokuntywiliselwa kwimizuzu eyi-120. Usekwinkonzo emva kweenyanga ezili-18.
Obu buchule buvela kumatshini wangaphakathi, ukulinganisa okuguquguqukayo, kunye nokuvavanya umthwalo-konke phantsi kophahla olunye. Akukho kulibaziseka kunikezelo lwangaphandle. Akukho nto ithile yokukhukuliseka phakathi komzobo wobunjineli kunye neyunithi yokugqibela.
Ukukhetha umlandeli wakho olandelayo woMlilo: Iitshekhi ezintathu ezingaxoxisiyo
Ngaphambi kokuba usayine kuyo nayiphi na iyunithi, qinisekisa ezi-ephepheni kunye nomntu:
I-Static pressure curve kwi-100% RPM, hayi nje incopho yeCFM. Buza itshathi epheleleyo ye-P-Q yegophe-hayi nje inombolo yesihloko. Ukuba abafuni ukwabelana ngayo, hamba. Idata yokunciphisa ubushushu bokwenyani: Yehla kangakanani i-airflow kwi-70°C ambient? Kwi-100°C? “Ayivavanywanga ukuya kwi-100°C”—kodwa “igcina i-≥92% elinganiswe ngokuhamba komoya kwi-100°C kwindawo ejikeleze imizuzu eyi-120.” Uxwebhu lwenkonzo yommandla: Ngaba le ncwadana yokulungisa ibhalelwe abacimi-mlilo—hayi amagcisa emizi-mveliso? Ngaba ibandakanya i-torque specs kwi-fastener nganye, ukunyamezela ukulungelelaniswa kwe-duct, kunye ne-diagnostic-mode diagnostics (umzekelo, "i-vibration ngaphezu kwe-4.2 mm / s RMS kwi-1,750 rpm = ukuthwala ukunxiba> 15%)? A Firefiriefirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifirifieri ayisosixhobo nje kuphela. Kukuphindaphinda amandla. Ijika ukudinwa kobushushu kwi-egress elawulwayo. Iguqula iqanda elibonakalayo libe yimizila yokubona enokusetyenzwa. Inika abalawuli besiganeko imizuzu-hayi imizuzwana-yokugqiba.
Zibo Hongcheng Fan Co., Ltd. uyawakha ngaloo ndlela-hayi ukuba spec sheets, kodwa fireground real. Indlela yabo ibonisa inyaniso elula: xa imizuzwana ibala, ukuthembeka ayisiyonto. Yeyona metric kuphela ebalulekileyo.
