2.Umgaqo wokusebenza

2.1 Ulwelo lungena kumzimba wempompo

  • Indlela yokungena kwamanzi: Ulwelo lungena kumzimba wempompo ngombhobho wokungena, ngokuqhelekileyo ngombhobho wokufunxa kunye nevalve yokufunxa.
  • Idayamitha yokungena kwamanzi: Imiselwe ngokusekelwe kwiinkcukacha zempompo kunye neemfuno zoyilo.

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
