Izibonelelo zemizi-mveliso azifuni abalandeli abaphezulu-zifuna ukuhamba komoya okukrelekrele. Xa abo basebenza kwimigodi yamalahle, kwimizi-mveliso yemichiza, okanye kumagumbi okubambisa izibilini bekhalaza ngengxolo ephazamisa unxibelelwano—okanye xa amaqela anyamekela izinto ezonakeleyo enikela ingxelo yokuba sele ekhulile ngenxa yokungcangcazela—oyena nobangela udla ngokuba “ngumoya omninzi.” Idla ngokuba njalo fan enengxolo ephantsi eyenziwe ngobunjineli ukudibanisa: ukungahambelani kweegophe zoxinzelelo lwestatic, iirotha ezingalungelelananga, okanye izindlu ezandisa isandi endaweni yokuyidambisa.
Siye savavanya ngaphezulu kwe-47 yeeyunithi ze-axial kunye ne-centrifugal kwimizi-mveliso yamandla eshushu e-Shandong-ngamnye ubanga "ukusebenza ngokuzolileyo." Kuphela i-11 edibene ne-ISO 5801 yemida yamandla esandi kumthwalo opheleleyo. Abanye badlula i-82 dB (A) kwi-1 mitha-ayimkelekanga kufuphi neepaneli zokulawula okanye kwii-8-hour shifts. Ukusebenza kwabalandeli behlabathi bokwenene bengxolo ephantsi akuchazwa ngamabango ekhathalogu decibel. Kulinganiswa ekunciphiseni ukukhathala kwabaqhubi, ukuthwala ubomi bokwandiswa, kunye namandla agcinwe xa umlandeli engazilwi.
Yintoni eyenza iFani ngeNtsholo ephantsi ngokwenene-Ngaphaya kweleyibhile
Umlandeli wokwenyani onengxolo ephantsi uqala ngoqeqesho lwe-aerodynamic-hayi nje i-RPM ecothayo. Imicimbi yokubala iBlade: I-7-blade impellers kwi-high-pressure centrifugals zisika ingxolo ye-tonal nge-6-9 dB ngokuchasene ne-5-blade equivalents. Kodwa i-blade geometry yodwa iyasilela ngaphandle kokwenziwa ngokuchanekileyo. Sifumene i-0.08 mm runout kwi-9-19 ekhuphisanayo yochungechunge lwe-impeller ebangele i-12 dB spike kwi-1,750 Hz-ehamba ngokuthe ngqo kwiifrikhwensi zokuthetha komntu. Yingakho ukulinganisa okuguquguqukayo kwi-G2.5 (nge-ISO 1940-1) akukhethi. Akuxoxiswana.
Ulwakhiwo luhambisa ingxolo kwakhona. Iicasing ze-Thin gauge zivakala njengeentloko zegubu. Idatha yethu yentsimi ibonisa ukuba izindlu ze-titanium-fan zinciphisa ukuhanjiswa kwe-structural-borne by 40% ngokubhekiselele kwi-carbon steel standard-nakwi-airflow efanayo. Kodwa i-titanium ayisoloko ifuneka. Uyilo oluqinisiweyo lwendonga ephindwe kabini kunye nokunyanzeliswa komgangatho ophakathi kwimodeli yoluhlu oluphakathi luzisa ukuphuculwa kwe-9-11 dB (A) ngesiqingatha seendleko.
Iimpazamo zofakelo zonakalisa nolona yilo lungcono. Ukukhwela i-axial fan yophahla ngokuthe ngqo kwii-purlins ezikhaphukhaphu? Oko kuguqula uphahla lonke lube yibhodi yesandi. Sicacisa ii-rubber-isolated mounts-kwaye ziqinisekise ngokufundwa kwe-accelerometer ngexesha lokuthunyelwa. Ukuba i-vibration idlula i-4.5 mm/s RMS kwizindlu ezithwele, siphinda sivavanye inkqubo yonke. Hayi ifeni. Ujongano.
Ukusebenza kakuhle kwamandla akubingelelwa-Kuyanyuswa
Abanye bacinga ukuba ingxolo ephantsi ithetha amandla aphantsi. Ayilunganga. Umlandeli ohambelana kakubi ubaleka kwi-62% esebenzayo ngelixa ekhala kwi-88 dB (A). Umlandeli ohambelana kakuhle wengxolo ephantsi ubetha ukusebenza kakuhle kwe-81% kwi-67 dB (A) -kuba isebenza kufuphi nencopho yayo ye-aerodynamic point, ayiminxeki okanye ilayishwe kakhulu.
Thatha uthotho lwe-FBD olunobungqina bokudubula kwefeni yasekhaya. Uyilo lwayo olujikelezayo olujikelezayo lwenqanaba elimbini luhambisa i-32,000 m³/h kwi-3,200 Pa static uxinzelelo-kodwa itsala i-18% ngaphantsi kwangoku kune-equivalents zenqanaba elinye kwindawo efanayo yomsebenzi. Ngoba? Ilahleko eyehlisiwe ye-swirl phakathi kwezigaba isika ukutsalwa okubangelwa sisidubedube. Ukuncipha kwesaqunge kuthetha ubushushu obuphantsi, ingxolo encinci, kunye nemfuno esezantsi ye-kW nge-1,000 m³/h.
Silandelela oku ngexesha lokwenyani. Umzi-mveliso wesamente omnye waphinda wafakela iifani zebhoyila ezintandathu ezizii-9-19 ezineenguqu ezinengxolo ephantsi. Ukonga amandla ngonyaka: 1.2 GWh. Ukunciphisa ingxolo kwizikhululo zabaqhubi: 14 dB(A). Ixesha lokubuyisela: Iinyanga ze-11-kungekhona kwintengiso "ezolileyo", kodwa ukusuka kwinzuzo enokulinganiswa ye-aerodynamic kunye nokunciphisa ilahleko yomatshini.
Ukwenza ngokwezifiso Kulapho iikhathalogu eziMgangatho zisilelayo
“Ingxolo ephantsi” ayithethi nto ngaphandle komxholo. Ifeni yokukhupha umsi etoneleni kufuneka ihlale izolile *ngelixa* ixhathisa i-400°C yerhasi yokunyuka. Ifeni ye-desulfurization idinga ukuxhathisa kokutya *plus* sub-70 dB(A) ukusebenza phakathi kwenkungu egcwele ikloridi. Inkcazo engaphandle kweshelufu iyawa apha.
Yiyo loo nto imveliso edibeneyo ibalulekile. Xa umxhasi efuna ifeni ye-titanium kwiindawo ezinobundlobongela ze-H₂S-kwaye efuna i-≤65 dB (A) kwiimitha ezi-3-asizange sikhuphe iinxalenye. Senze i-impeller yangaphakathi endlwini, sadibanisa indlu nge-argon-backing, safaka iibheringi ezigqunywe ngeceramic, kwaye saqinisekisa imveliso ye-acoustic kwirig yethu yovavanyo lwe-anechoic. Ixesha elipheleleyo lokukhokela: iiveki ze-14. Akukho kulalanisa kwingxolo, imfezeko yezinto eziphathekayo, okanye ukuhanjiswa.
Izixhobo eziphambili zokwenza ngokwezifiso esizisebenzisa mihla le:
Ukutshayela iBlade kwi-impedance ethile ye-duct system Ukubekwa komgca we-acoustic ilungelelaniswe kwiibhendi zefrikhwensi eziphambili-hayi ukugquma ingubo I-Motor-mount decoupling ukwahlula i-electromagnetic hum kwi-vibration yomatshini Indlela yokuqinisekisa uqhushumbo ihambelana ne-IEC 60079-0/1/31-hayi nje iibholiti ezivaliweyo Ukukhetha Umlandeli Wakho Olandelayo Wengxolo Ephantsi: Iitshekhi ezinokuSebenza
Ngaphambi kokuba uchaze, buza le mibuzo-uze uqinisekise iimpendulo ngeengxelo zovavanyo, hayi iincwadana:
Ngaba amandla esandi alinganiswa ngokwe-ISO 5801—okanye isandi nje soxinzelelo kumgama omnye? Ngaba i-curve esebenzayo ibonisa incopho>75% kwindawo yakho yokusebenza efunekayo? Ngaba ukuthwala izibalo zobomi ngokusekelwe kumthwalo we-L10 wangempela-hayi i-RPM enkulu yethiyori? Ngaba banokubonelela ngeqela lesithathu le-NVH (ingxolo-yokungcangcazela-bungqwabalala) ukuqinisekiswa koqwalaselo lwakho oluchanekileyo? EZibo Hongcheng Fan Co., Ltd., wonke umlandeli wengxolo ephantsi uhambisa inqanawa enesatifikethi esisayiniweyo sovavanyo lwe-acoustic kunye nemephu yokusebenza epheleleyo-kungekhona nje inqaku ledatha enye. Sakha apho ukuhamba komoya kuhlangabezana noxanduva: i-9,000 m² yomatshini ochanekileyo, ulungelelwaniso oluguqukayo, kunye novavanyo lomthwalo wokwenyani phantsi kweemeko ezifaniswayo zoshishino. Kuba ukupholisa okuthe cwaka akufuneki kube bubunewunewu. Kufuneka ibe sisiseko somsebenzi okhuselekileyo, osebenzayo nozinzileyo.
Kwiinjineli ezilinganisa impumelelo kwii-decibels ezithintelweyo kunye ne-kilowatts zigcinwe-kungekhona nje i-cubic metres eshukunyiswayo-isizukulwana esilandelayo se-teknoloji ye-fan yengxolo ephantsi sele isebenza. Akukho kwiilebhu. Emigodini. Kwizindlu zebhoyila. Kwiindawo zokugcinwa kweekhemikhali. Apho ukuthembeka akuthenjiswanga. Iqinisekisiwe.
