Izakhiwo zezimboni azidingi abalandeli abanomsindo omkhulu—zidinga ukugeleza komoya okuhlakaniphile. Lapho abasebenza ezimayini zamalahle, ezimbonini zamakhemikhali, noma ezindlini zokubhayela bekhala ngomsindo ophazamisa ukuxhumana—noma lapho amaqembu anakekelayo ebika ukuguga ngaphambi kwesikhathi ngenxa yokundindizela—akuvamile ukuba umsuka ube “nomoya omningi.” Kuvamile ifeni yomsindo ophansi engakhiwe kahle ukuhlanganisa: amajika omfutho we-static angafani, ama-rotor angalingani, noma izindlu ezikhulisa i-resonance esikhundleni sokuwudambisa.
Sihlole amayunithi e-axial nama-centrifugal angaphezu kuka-47 kuzo zonke izizinda zamandla ashisayo e-Shandong—ngasinye sithi “ukusebenza ngokuthula.” Eziyi-11 kuphela ezihlangabezane nemikhawulo yamandla omsindo we-ISO 5801 ngokulayisha okugcwele. Okunye kudlule u-82 dB(A) ngemitha elingu-1—akwamukeleki eduze kwamaphaneli okulawula noma amashifu wamahora angu-8. Ukusebenza kwabalandeli bomsindo ophansi emhlabeni wangempela akuchazwa ngezimangalo zekhathalogi ye-decibel. Kukalwa ngokunciphisa ukukhathala komsebenzisi, ukuthwala isandiso sempilo, namandla alondolozwayo lapho ifeni ingazilwisi.
Yini eyenza Umlandeli Ube Nomsindo Ophansi Ngempela—Ngaphandle Kwelebula
Umlandeli wangempela womsindo ophansi uqala ngesiyalo se-aerodynamic—hhayi nje i-RPM ehamba kancane. Izibalo zeblade zibalulekile: Ama-impeller angama-7-blade kuma-centrifugal anengcindezi ephezulu asika umsindo we-tonal ngo-6–9 dB uma kuqhathaniswa nokulingana kwamablade angu-5. Kodwa i-blade geometry iyodwa ihluleka ngaphandle kokukhiqiza ngokunemba. Sithole ukugijima okungu-0.08 mm ochungechungeni lwe-impeller engu-9-19 esiqhudelana nayo okubangele ukukhuphuka okungu-12 dB ku-1,750 Hz—imvamisa yenkulumo yomuntu egqagqene ngokuqondile. Kungakho ukulinganisa okuguquguqukayo ku-G2.5 (nge-ISO 1940-1) kungenakuzikhethela. Akuxoxiswana ngakho.
Isakhiwo sidlulisa umsindo futhi. Amakesi ama-Thin gauge azwakala njengekhanda le-drumhead. Idatha yethu yasensimini ibonisa ukuthi izindlu zabalandeli be-titanium zinciphisa ukudluliswa kwesakhiwo ngo-40% uma kuqhathaniswa ne-carbon steel ejwayelekile—ngisho nasekugelezeni komoya okufanayo. Kodwa i-titanium ayidingeki ngaso sonke isikhathi. Imiklamo eqinisiwe yodonga olukabili enongqimba oluvinjiwe kumamodeli webanga eliphakathi iletha ukuthuthukiswa okungu-9–11 dB(A) ngesigamu sezindleko.
Amaphutha okufaka alimaza ngisho nomklamo ongcono kakhulu. Ukukhweza ifeni ye-axial yophahla ngqo kuma-purlins angasindi? Lokho kuguqula uphahla lonke lube ibhodi lokukhala. Sicacisa izikhwezi ezihlukaniswe ngenjoloba—futhi siziqinisekise ngokufundwa kwe-accelerometer ngesikhathi sokusebenza. Uma ukudlidliza kudlula u-4.5 mm/s RMS ezindlini ezinezinhlamvu, sihlola kabusha yonke isistimu. Hhayi umlandeli. Isixhumi esibonakalayo.
Ukusebenza Amandla Akunikelwa—Kuyakhuliswa
Abanye bacabanga ukuthi umsindo ophansi usho amandla amancane. Akulungile. Umlandeli ongafaniswa kahle ugijima ngo-62% osebenza kahle ngenkathi ememeza ngo-88 dB(A). Ifeni ehambisana kahle yomsindo ophansi ifinyelela ukusebenza kahle okungu-81% ku-67 dB(A)—ngoba isebenza eduze nephoyinti layo eliphakeme le-aerodynamic, ayiminyanisiwe noma ayilayishiwe.
Thatha uchungechunge lwe-FBD fan yokungenisa umoya engaqhumi. Idizayini yayo yesiteji esikabili ezungezayo ihamba ngo-32,000 m³/h ku-3,200 Pa static pressure—kodwa idonsa ngo-18% ngaphansi kwamanje kunokulingana kwesiteji esisodwa endaweni efanayo yomsebenzi. Kungani? Ukulahlekelwa kwe-swirl okuncishisiwe phakathi kwezigaba kunciphisa ukudonsa okubangelwa isiyaluyalu. Ukuncipha kwesiyaluyalu kusho ukushisa okuncane, umsindo omncane, nesidingo esiphansi se-kW ngo-1,000 m³/h.
Silandelela lokhu ngesikhathi sangempela. Isitshalo esisodwa sikasimende sifake kabusha amafafeni ayisisekelo ayisithupha okubhayela angu-9-19 ngokuhlukahluka komsindo ophansi. Ukonga amandla ngonyaka: 1.2 GWh. Ukunciphisa umsindo eziteshini zabasebenzisi: 14 dB(A). Isikhathi sokukhokha: izinyanga eziyi-11—hhayi kusukela ekukhangiseni “okuthule,” kodwa kusukela ezinzuzweni ezilinganisekayo ze-aerodynamic kanye nokulahlekelwa kwemishini okuncishisiwe.
Ukwenza Ngokwezifiso Lapho Amakhathalogi Ajwayelekile Ehluleka
“Umsindo omncane” awusho lutho ngaphandle komongo. Ifeni yokukhipha intuthu emhubheni kufanele ithule *ngenkathi* imelana nokuqhuma kwegesi engu-400°C. Ifeni ye-desulfurization idinga ukusebenza kwe-corrosion resistance *plus* sub-70 dB(A) phakathi kwenkungu egcwele i-chloride. Imininingwane engekho eshalofini iyagoqa lapha.
Yingakho ukukhiqiza okuhlanganisiwe kubalulekile. Lapho iklayenti lidinga ifeni ye-titanium ezindaweni ezinolaka ze-H₂S—futhi lifuna u-≤65 dB(A) ngamamitha angu-3—asizange sithole izingxenye. Sakha i-impeller endlini, sashisela indlu nge-argon-backing, sasebenzisa ama-ceramic-coated bearings, futhi saqinisekisa ukuphuma kwe-acoustic kumshini wethu wokuhlola we-anechoic. Isikhathi sokuhola esiphelele: amaviki angu-14. Akukho ukuyekethisa emsindweni, ubuqotho bezinto ezibonakalayo, noma ukulethwa.
Izinsimbi zokwenza ngokwezifiso eziyinhloko esizisebenzisa nsuku zonke:
Ukuthuthukisa ukushanela i-blade nge-impedance ethile yesistimu yamapayipi Ukubekwa komugqa we-Acoustic ishuniswe kumabhendi efrikhwensi abusayo—hhayi ukumboza ingubo I-motor-mount decoupling ihlukanisa i-electromagnetic hum ekudlidlizeni komshini Indlela yesitifiketi sokuvikela ukuqhuma iqondaniswe ne-IEC 60079-0/1/31—hhayi nje izindawo ezivalekile ezinebhawodi Ukukhetha Umlandeli Wakho Olandelayo Womsindo Ophansi: Amasheke Angenzeka
Ngaphambi kokucacisa, buza le mibuzo—bese uqinisekisa izimpendulo ngemibiko yokuhlolwa, hhayi izincwajana:
Ingabe amandla omsindo akalwa nge-ISO 5801—noma ingcindezi yomsindo nje ebangeni elilodwa? Ingabe ijika elisebenza kahle libonisa ukuphakama >75% endaweni yakho yokusebenza edingekayo? Ingabe ukubala kwempilo kusekelwe kumthwalo wangempela we-L10—hhayi i-RPM enkulu yethiyori? Ingabe bangakunikeza ukuqinisekiswa kwe-NVH yenkampani yangaphandle (noise-vibration-harshness) yokucushwa kwakho okunembile? E-Zibo Hongcheng Fan Co., Ltd., wonke abalandeli abanomsindo ophansi bahamba ngemikhumbi ngesitifiketi sokuhlola se-acoustic esayiniwe kanye nemephu yokusebenza egcwele—hhayi nje iphuzu elilodwa ledatha. Sakha lapho ukugeleza komoya kuhlangabezana nokuziphendulela: 9,000 m² womshini onembayo, ukulinganisa okuguquguqukayo, nokuhlolwa komthwalo wangempela ngaphansi kwezimo zemboni ezilingisayo. Ngoba ukupholisa okuthulile akufanele kube ukunethezeka. Kufanele kube yisisekelo sokusebenza okuphephile, okuphumelelayo, nokuqhubekayo.
Konjiniyela abakala impumelelo ngama-decibel agwenyiwe kanye nama-kilowatts alondoloziwe—hhayi ama-cubic metres kuphela ahanjisiwe—isizukulwane esilandelayo sobuchwepheshe babalandeli bomsindo ophansi sesiyasebenza kakade. Hhayi kumalebhu. Ezimayini. Ezindlini zama-boiler. Ezindaweni zokuqukatha amakhemikhali. Lapho ukwethembeka kungathenjiswa khona. Kufakazelwe.
