Ndeapi maparamita makuru emufefetera?

Iwo makuru ma paramita, maitiro kune fan, ari mana muhuwandu: Kugona (V) Kudzvanya (p) Kubudirira (n) Kumhanya kwekutenderera (n min.^-1)

Chii chinonzi Capacity?

Kugona ndiko kuwanda kwemvura inofambiswa nefeni, muhuwandu, mukati mechikamu chenguva, uye inowanzoratidzwa mu m.³/h, m³/min.,m³/sec.

Chii Chinonzi Total Pressure uye ndingaiverenga sei?

Iyo yakazara dzvinyiriro (pt) ihuwandu hweiyo static pressure (pst), kureva simba rinodiwa kuti rimirire kupesana kwakapokana kubva muhurongwa, uye simba remagetsi (pd) kana kinetic simba rinopihwa kumvura inofamba (pt = pst + pd ) Simba resimba rinoenderana nekumhanya kwemvura (v) uye chaiyo giravhiti (y).

formula-dinamic-pressure

Kupi:
pd= dynamic pressure (Pa)
y=kukweva kwemvura chaiyo(Kg/m3)
v = kumhanya kwemvura pakuvhurwa kwe fan kunoshandiswa nesystem (m/sec)

formula-capacity-pressure

Kupi:
V= kugona (m3/sec)
A= geji yekuvhura yakashandiswa nehurongwa (m2)
v= kumhanya kwemvura pakuvhurwa kwe fan kunoshandiswa nesystem (m/sec)

Chii chinobuda uye ndingachiverenga sei?

Iko kunyatsoita chiyero pakati pesimba rinoburitswa nefeni uye simba rekuisa kune fan inotyaira mota

Kupi:
n= kushanda zvakanaka (%)
V= kugona (m3/sec)
pt = simba rakanyura (KW)
P = kumanikidzwa kwese (daPa)

Chii chinonzi kumhanya kwekutenderera? Chii chinoitika kuchinja nhamba yemarevolutions?

Iko kumhanya kwekutenderera huwandu hwemarevolutions iyo fan impeller inofanirwa kumhanya kuitira kuti isangane nekuita zvinodiwa.
Sezvo huwandu hwemabhindauko hunosiyana (n), nepo mvura chaiyo inokwevera pasi ichiramba yakatsiga (?), misiyano inotevera inoitika:
Iyo simba (V) yakanyatso kuenderana nekumhanya kwekutenderera, saka:

t (1)

Kupi:
n= kumhanya kwekutenderera
V= kugona
V1 = hutsva hutsva hunowanikwa pakusiyana kwekumhanya kwekutenderera
n1= kumhanya kutsva kwekutenderera

Kupi:
n= kumhanya kwekutenderera
pt = kumanikidzwa kwese
pt1= kudzvanywa kutsva kwakawanikwa pakusiyana kwekumhanya kwekutenderera
n1= kumhanya kutsva kwekutenderera

Simba rakanyura (P) rinosiyana necube yekutenderera reshiyo, saka:

formula-speed-rotation-abs.power_

Kupi:
n= kumhanya kwekutenderera
P= abs. simba
P1= magetsi matsva anowanikwa pakusiyana kwekumhanya kwekutenderera
n1= kumhanya kutsva kwekutenderera

Iyo chaiyo giravhiti inogona kuverengerwa sei?

Iyo chaiyo giravhiti (y) inogona kuverengerwa neinotevera formula

Kupi:
273= zero yakakwana(°C)
t = tembiricha yemvura (°C)
y= simba rinokwevera mhepo pa t C(Kg/m3)
Pb = barometric pressure (mm Hg)
13.59= mercury chaiyo giravhiti pa0 C(kg/dm3)

Kuti zvive nyore kuverenga, huremu hwemhepo patembiricha dzakasiyana uye kureba asl zvakaverengerwa patafura pazasi:
