SU'AALO BADAN LA IS WEYDIIYO

Waa kuwee halbeegyada ugu muhiimsan ee hawo -mareenka?

Halbeegyada ugu waaweyn, oo u gaar ah taageere, waa afar tiro: Awood (V) Cadaadis (p) Karti (n) Xawaaraha wareegga (n min.-1)

Waa maxay Awooddu?

Awooddu waa xaddiga dareeraha uu dhaqaajiyay marawaxadda, mugga, halbeeg gudaheed, waxaana badanaa lagu muujiyaa m3/h, m3/daqiiqo., m3/seken.

Waa maxay Cadaadiska Guud iyo sideen u xisaabin karaa?

Cadaadiska guud (pt) waa wadarta cadaadiska ma guurtada ah (pst), yacnii tamarta loo baahan yahay si looga hortago jahawareerka iska soo horjeeda ee nidaamka, iyo cadaadiska firfircoon (pd) ama tamarta kinetic ee la siiyay dareeraha socda (pt = pst + pd ). Cadaadiska firfircoon wuxuu ku xiran yahay xawaaraha dareeraha (v) iyo cufnaanta gaarka ah (y).

formula-dinamic-pressure

Xagee:
pd = cadaadis firfircoon (Pa)
y = cufnaanta gaarka ah ee dareeraha (Kg/m3)
v = xawaaraha dareeraha ee furitaanka marawaxadda ee uu shaqeeyay nidaamka (m/sek)

formula-capacity-pressure

Xagee:
V = Awoodda (m3/sek)
A = cabirka furitaanka ee uu shaqeeyay nidaamka (m2)
v = xawaaraha dareeraha ee furitaanka marawaxadda ee uu shaqeeyay nidaamka (m/sek)

Waa maxay soosaarka iyo sideen u xisaabin karaa?

Wax -ku -oolnimadu waa saamiga u dhexeeya tamarta ay soo saarto taageere iyo soo -gelinta tamarta ee matoorka wadista marawaxadda

output efficency formula

Xagee:
n = hufnaan (%)
V = Awoodda (m3/sek)
pt = awoodda la nuugo (KW)
P = cadaadiska guud (daPa)

Waa maxay xawaaraha wareegga? Maxaa dhacaya beddelidda tirada kacaannada?

Xawaaraha wareegga ayaa ah tirada kacdoonnada ay tahay in qofka kiciya taageereha uu socodsiiyo si loo buuxiyo shuruudaha waxqabadka.
Maaddaama tirada kacdoonnadu ay kala duwan yihiin (n), halka cufnaanta cufnaanta gaarka ahi si joogto ah u joogto (?), Kala duwanaanshaha soo socda ayaa dhacaya:
Awoodda (V) waxay si toos ah ugu dhigantaa xawaaraha wareegga, sidaa darteed:

t (1)

Xagee:
n = xawaaraha wareegga
V = karti
V1 = Awood cusub oo la helay marka la kala duwanaado xawaaraha wareegga
n1 = xawaaraha cusub ee wareegga

t (2)

Xagee:
n = xawaaraha wareegga
pt = cadaadiska guud
pt1 = cadaadis guud oo cusub oo la helay marka la eego kala duwanaanta xawaaraha wareegga
n1 = xawaaraha cusub ee wareegga

Awoodda la nuugay (P) waxay ku kala duwan tahay cube of ratio rotation, sidaa darteed:

formula-speed-rotation-abs.power_

Xagee:
n = xawaaraha wareegga
P = maqnaansho. awood
P1 = galinta korantada cusub ee la helay marka la kala duwanaado xawaaraha wareegga
n1 = xawaaraha cusub ee wareegga

Sidee baa loo xisaabin karaa cufnaanta gaarka ah?

Cufnaanta gaarka ah (y) waxaa lagu xisaabin karaa qaacidada soo socota

gravity formula

Xagee:
273 = Eber buuxa (° C)
t = heerkulka dareeraha (° C)
y = cuf -cufnaanta hawada ee t C (Kg/m3)
Pb = cadaadiska barometric (mm Hg)
13.59 = meerkurida cufnaanta gaarka ah ee 0 C (kg/dm3)

Si loo fududeeyo xisaabinta, miisaanka hawada heerkul kala duwan iyo asl ayaa lagu daray shaxda hoose:
