IMIBUZO EBUZWA QHO

Zeziphi ezona zinto ziphambili kumatshini wokuphefumla?

Iiparameter eziphambili, uphawu kumlandeli, zine kumanani: Amandla (V) Uxinzelelo (p) Ukusebenza ngokufanelekileyo (n) Isantya sokujikeleza (n min.-1)

Yintoni amandla?

Ubungakanani bubungakanani bolwelo oluhanjiswe ngumtshini, ngevolumu, ngaphakathi kweyunithi yexesha, kwaye ihlala ichazwa m3/ h, m3/ imiz., m3/ umzuzwana.

Luthini uxinzelelo olupheleleyo kwaye ndingabala njani?

Uxinzelelo olupheleleyo (pt) sisiphumo soxinzelelo lwe-static (pst), okt amandla afunekayo ukumelana nokuchasana nokuphikisana nenkqubo, kunye noxinzelelo lwamandla (pd) okanye amandla e-kinetic anikezelwe kulwelo oluhambayo (pt = pst + pd ). Uxinzelelo olunamandla luxhomekeke kwisantya samanzi (v) kunye nomxhuzulane othile (y).

formula-dinamic-pressure

Phi:
pd = uxinzelelo olunamandla (Pa)
y = umxhuzulane othile wolwelo (Kg / m3)
v = isantya samanzi xa kuvulwa ifeni esebenza yinkqubo (m / sec)

formula-capacity-pressure

Phi:
V = umthamo (m3 / sec)
Umlinganiso = wokuvulwa kokusebenza kwenkqubo (m2)
v = isantya samanzi xa kuvulwa ifeni esebenza yinkqubo (m / sec)

Yintoni imveliso kwaye ndingayibala njani?

Ukusebenza ngokukuko ngumlinganiso phakathi kwamandla aveliswe yifeni kunye negalelo lamandla kumqhubi oqhuba imoto

output efficency formula

Phi:
n = ukusebenza (%)
V = umthamo (m3 / sec)
pt = amandla angenisiweyo (KW)
P = uxinzelelo olupheleleyo (daPa)

Yintoni isantya sokujikeleza? Kwenzeka ntoni ukutshintsha inani leenguqu?

Isantya sokujikeleza linani leenguqu ekufuneka inyanzelwe ngumqhubi ukuze ihlangabezane neemfuno zomsebenzi.
Njengokuba inani lotshintsho lisahluka (n), ngelixa ulwelo oluthile lomxhuzulane luhlala luzinzile (?), Oko kwahluka kulandelayo kuyenzeka:
Umthamo (V) ulingana ngokuthe ngqo kwisantya sokujikeleza, ke ngoko:

t (1)

Phi:
n = isantya sokujikeleza
V = umthamo
V1 = amandla amatsha afunyenwe ngokwahluka kwesantya sokujikeleza
n1 = isantya esitsha sokujikeleza

t (2)

Phi:
n = isantya sokujikeleza
pt = uxinzelelo olupheleleyo
pt1 = uxinzelelo olupheleleyo lufunyenwe ngokwahluka kwesantya sokujikeleza
n1 = isantya esitsha sokujikeleza

Amandla afunxwe (P) ayahluka ngekyhubhu yomjikelezo wokujikeleza, ke:

formula-speed-rotation-abs.power_

Phi:
n = isantya sokujikeleza
P = ukungabikho. amandla
I-P1 = igalelo elitsha lombane elifunyenwe ngokwahluka kwesantya sokujikeleza
n1 = isantya esitsha sokujikeleza

Ungabalwa njani ubukhulu bomxhuzulane?

Umxhuzulane othile (y) unokubalwa ngale ndlela ilandelayo

gravity formula

Phi:
273 = zero ngokupheleleyo (° C)
t = ulwelo olunamandla (° C)
y = ubunzima bomxhuzulane othile kwi-t C (Kg / m3)
Pb = uxinzelelo lwe-barometric (mm Hg)
13.59 = i-mercury gravity ethile kwi-0 C (kg / dm3)

Ukulungiselela ukubala, ubunzima bomoya kumaqondo obushushu ahlukeneyo kunye neendawo eziphakamileyo ze-asl zibandakanyiwe kule theyibhile ingezantsi:
