Ke Eng Hantle-ntle Se Khannang Theko ea Centrifugal Exhaust Fan blower
Lintlha tse tharo li laola litheko-'me tse peli tsa tsona ha li bonahale ho leqephe la lintlha.
- Phallo ea moea le moeli oa moralo oa khatello: Fene e lekantsoeng 12,000 m³/h ho 1,800 Pa ha e rekoe ka theko e lekanang le ea e tsamaisang molumo o tšoanang ho 2,200 Pa. Ea morao e hloka sekhutlo se phahameng sa blade, clearance clearance, le li-bearings tsa boemo bo holimo-e eketsa 18–26% ho litšenyehelo tsa motheo. Litekong tsa rona tsa lab, balateli ba nang le ≤3% ea marang-rang ea moralo ba ile ba hloleha ho netefatsoa ka mocheso tlas'a ts'ebetso e tsoelang pele ea 40 ° C.
- Botšepehi ba tsamaiso ea lintho tse bonahalang: Stainless steel (304 vs. 316) ha e bue ka ho hanyetsa ho bola feela. E ama ho cheseha ha mocheso, ho se tsamaisane ha mocheso le lisebelisoa tsa enjene, le ho thothomela ha nako e telele. Fane ea 316SS e nang le casing e nang le laser-welded le shaft seal e koahetsoeng ka ceramic e bitsa 41% ho feta 304 e lekanang le eona-empa e nka 3.2 × nako e telele ho tsoa ho metsi a litšila a tletseng chlorine.
- Boemo ba ho kopanya likoloi: Li-motors tsa IE3 li eketsa ~ 12% ho feta IE2. Empa mapheo a kopantsoeng a VFD-reading, insulation Class H, le IP55+ e kampetsoeng e bitsa chelete e 'ngoe ea 9–15%. Re lekola lintlha tsa tšimo: li-unit tse nang le mochini o kopanyang li-motor-fan (ha ho na lebanta, ha ho likhokahano tsa khokahano) li bonts'a mefokolo e fokolang ea 29% litsing tsa ts'ebeletso tsa lilemo tse 5.
Tsena ha se liphapang tsa khopolo-taba. Li lekantsoe ka lihora tsa mosebetsi oa ho lokisa, ho koaloa ho sa reroang, le ho baloa ha limithara tsa matla. Theko ea seqhutsu sa fene ea $1,850 centrifugal e shebahala e khahleha—ho fihlela koloi ea eona e hula 8.7 kW sebakeng sa 7.2 kW e tšepisitsoeng ka phallo e lekantsoeng. Ke $ 1,040 / selemo e eketsehileng ka motlakase ho $ 0.12 / kWh.

Bareki ba bang ba kopa litefiso ho tsoa ho barekisi ba bahlano, ebe ba fana ka tefiso e tlase haholo. Re hlahlobile merero e joalo e 47 lilemong tse tharo tse fetileng. Linyeoeng tse 31, moreki ea hapileng o ile a nka sebaka sa tšepe ea thinner gauge, boemo bo theohileng, kapa o tlohetse balancing e matla.

- E hloka setifikeiti sa ho leka-lekanya sa ISO 1940-1 G2.5, eseng feela “ho leka-lekana.” Re lekola fene e 'ngoe le e 'ngoe ea centrifugal exhaust pele e romelloa-le ho rekota amplitude, phase, le ho lokisa libaka.
- Hlalosa bonyane botenya ba thepa: mohlala, "Casing ≥3.0 mm SS316, impeller ≥4.5 mm, plate support plate ≥6.0 mm." Litšepe tse tšesaane. Ho tenyetseha ho baka mapetsong a mokhathala—’me lerata le phahama ka holimo ho 82 dB(A).
- Netefatsa hore data ea nameplate ea koloi e tsamaisana le ntlha ea mosebetsi oa fan. Eseng feela "IE3". Netefatsa li-amps tsa 'nete tse tletseng moroalo, ntlha ea litšebeletso (bonyane ba 1.15), le sehlopha sa tšireletso ea mocheso. Re fumane 14% ea theko e tlase e romelloang ka ntle ho naha bakeng sa tšebeliso e mpe ea boleng bo holimo.
Taeo ena e eketsa 3–7% ho litšenyehelo tsa pele—empa e fokotsa TCO ea lilemo tse 5 ka 22–39%, ho ipapisitsoe le tlhahlobo ea bophelo ba bareki.
