2.2 I-Impeller ikhawulezisa ulwelo
- Isantya se-impeller: Ngokuqhelekileyo kwi-1450 RPM okanye i-2900 RPM (ukuguqulwa ngomzuzu), kuxhomekeke kuyilo lwempompo kunye nokusetyenziswa.
- amandla e-centrifugal: I-impeller ijikeleza ngesantya esiphezulu esiqhutywa yi-motor, kwaye i-liquid ikhawuleza yi-centrifugal force.
2.3 Ulwelo luqukuqela ukuya kumphandle wempompo yomzimba
- Uyilo lwembaleki: Ulwelo olukhawulezayo luphumela ngaphandle kunye nomjelo wokuhamba we-impeller kwaye lungena kwindawo ye-volute yempompo yomzimba.
- Uyilo lweVolute: Uyilo lwevolonti lunceda ukuguqula amandla ekinetic olwelo abe ngamandla oxinzelelo.
2.4 Ulwelo olukhutshwa kumzimba wempompo
- Indlela yokukhupha amanzi: Ulwelo luyancipha ngakumbi kwi-volute kwaye luguqulelwe kumandla oxinzelelo, kwaye lukhutshwe kumzimba wempompo ngombhobho wokukhupha amanzi.
- Idayamitha yokuphuma: Imiselwe ngokusekelwe kwiinkcukacha zempompo kunye neemfuno zoyilo.
3.inkqubo yokuguqula amandla
3.1 Ukuguqulwa kwamandla eKinetic
- Ukukhawuleza kwe-Impeller: I-liquid izuza amandla e-kinetic phantsi kwesenzo se-impeller, kwaye isantya sayo siyanda.
- Ifomula yamandla eKinetic:( E_k = \ frac {1}{2} mv^2 )
- (E_k): amandla ekinetic
- (m): Ubunzima bolwelo
- (v): isantya solwelo
3.2 Ukuguqulwa kwamandla oxinzelelo
- Ukunciphisa umthamo: Ulwelo luyancipha kwi-volute, kwaye amandla e-kinetic aguqulwa abe ngamandla oxinzelelo.
- Bernoulli equation( P + \frac{1}{2} \rho v^2 + \rho gh = \okubhaliweyo{rhoqo} )
- (P): Uxinzelelo
- ( \ rho ): ukuxinana kolwelo
- (v): isantya solwelo
- (g): isantya somxhuzulane
- (h): ukuphakama
