Zvivakwa zvemaindasitiri hazvidi mafeni ane ruzha-zvinoda kufefeterwa kwemhepo. Apo vashandi vomumigodhi yemarasha, mafekitari emakemikari, kana kuti makamuri anobira mvura vanogunun’una pamusoro poruzha runovhiringidza kurukurirano—kana kuti apo mapoka anogadziridza anoshuma kupera nguva isati yakwana nemhaka yokudedera—chisakiso chikuru hachiwanzova “mhepo yakawandisa.” Kazhinji yakanyatsogadzirwa yakaderera-ruzha fan kubatanidzwa: kusanganisa static pressure curves, unbalanced rotor, kana dzimba dzinosimudzira resonance panzvimbo yekuidzima.
Takaedza anopfuura makumi mana nemanomwe axial uye centrifugal mauniti pamatatu emagetsi emagetsi ekuShandong - imwe neimwe ichiti "kushanda kwakanyarara." 11 chete yakasangana neISO 5801 inonzwika masimba emagetsi pamutoro uzere. Zvimwe zvakapfuura 82 dB (A) pamamita 1-zvisingagamuchirwi pedyo nemapaneru ekudzora kana kwe8-awa kuchinja. Real-world yakaderera-ruzha fan performance haina kutsanangurwa nekatalogi decibel zvichemo. Inoyerwa mukuderedza kuneta kwevashandisi, kutakura hupenyu hwekuwedzera, uye simba rinochengetwa kana fan ikasarwa yega.
Chii Chinoita Kuti Fani Aite Noise Yakaderera-Kupfuura Label
Fani yechokwadi yakaderera-ruzha inotanga neaerodynamic chirango-kwete chete inononoka RPM. Blade count nyaya: 7-blade impellers pa-high-pressure centrifugals inocheka tonal ruzha ne6-9 dB maringe ne5-blade yakaenzana. Asi blade geometry chete inokundikana pasina kunyatsogadzira kugadzira. Isu takawana 0.08 mm runout mumukwikwidzi's 9-19 akatevedzana impeller yakakonzera gumi nemaviri dB spike pa1,750 Hz-yakananga inopindirana mataurirwo emunhu. Ndokusaka kuenzanisa kwesimba kuG2.5 (pa ISO 1940-1) kusiri sarudzo. Hazvitaurike.
Chimiro chinofambisa ruzha zvakare. Matete-gauge macasings anorira senge drumheads. Yedu yemunda data inoratidza titanium-fan dzimba dzinoderedza kutapurirana-kutakurwa ne40% kupesana neyakajairwa kabhoni simbi-kunyangwe pamhepo yakafanana. Asi titanium haidiwi nguva dzose. Yakaomeswa-yakaomeswa-madziro madhizaini ane akamanikidzwa-layer kunyorovesa mukati me-renji modhi inoburitsa 9-11 dB (A) kuvandudzwa nehafu yemutengo.
Kukanganisa kwekuisa kunokanganisa kunyangwe dhizaini yakanakisa. Kukwira denga axial fan zvakananga kune lightweight purlins? Izvozvo zvinoshandura denga rose kuva bhodhi rokurira. Isu tinotsanangudza mamoiri akasarudzika erabha-uye toasimbisa neaccelerometer kuverenga panguva yekutumwa. Kana vibration ichipfuura 4.5 mm/s RMS pakubereka dzimba, tinoongorora zvakare sisitimu yese. Kwete fani. The interface.
Kushanda Kwesimba Haina Kubayirwa-Iyo Inowedzerwa
Vamwe vanofungidzira kuti ruzha-rushoma zvinoreva simba shoma. Zvakaipa. Fani isina kufananidzwa inomhanya pa62% kunyatsoshanda uku ichiridza mhere pa88 dB (A). Iyo yakanyatsoenderana yakaderera-ruzha fan inorova 81% kunyatsoshanda pa67 dB(A) -nekuti inoshanda padyo nepamusoro peaerodynamic point, isina kukachidzwa kana kuremerwa.
Tora iyo FBD yakatevedzana kuputika-uchapupu hwemuno ventilation fan. Dhizaini yayo inotenderera-inotenderera mbiri-nhanho inofambisa 32,000 m³/h pa3,200 Pa static pressure-asi inokwevera 18% yakaderera ikozvino pane imwe-nhanho yakaenzana panzvimbo imwechete yebasa. Sei? Yakaderedzwa swirl kurasikirwa pakati pematanho inocheka turbulence-induced drag. Kusagadzikana kunoreva kushoma kupisa, kushoma ruzha, uye kushomeka kwekW pa1,000 m³/h.
Isu tinotevedzera izvi munguva chaiyo. Imwe simende yakarembera nhanhatu 9-19 boiler primary mafeni ane yakaderera-ruzha akasiyana. Kuchengetedza kwegore negore simba: 1.2 GWh. Kuderedza ruzha pazviteshi zvevashandi: 14 dB (A). Nguva yekubhadhara: Mwedzi ye11-kwete kubva "kunyarara" kushambadzira, asi kubva pakuyerwa kweaerodynamic kuwana uye kuderedzwa kwemagetsi kurasikirwa.
Customization Ndiko uko Standard Catalogs Inokundikana
“Ruzha rushoma” harurevi chinhu pasina mamiriro. Feni inopedza utsi mukotoni inofanira kugara yakanyarara *ipo* ichidzivisa kusundwa kwegasi 400°C. A desulfurization fan inoda corrosion resistance *plus* sub-70 dB(A) oparesheni pakati pe chloride-laden mhute. Off-the-sherufu specs inodonha pano.
