1. Simba Rinobudirira:Inozivikanwa seSimba rinobuda. Inoreva simba rakawanikwa ne
mvura inoyerera kuburikidza nemvura yepombi mune imwe nguva yenguva kubva kumvura
pombi.
Pe = ρ GQH / 1000 (KW)
ρ - Kuwedzeredza kwemvura kununurwa nePump (KG / M3)
γ - Kurera kweMvura Kununurwa nePump (N / M3)
Q - PUMP FLEE (M3 / S)
H - pombi musoro (m)
G - Kuwedzera kweGravity (M / S2).
2.fficency
Inoreva iyo muzana yeiyo huwandu hwesimba rinoshanda re pombi kune iyo shaft simba, inoratidzwa na η. Hazvibvirike kune ese shaft simba kuti aendeswa kune iyo mvura, uye kune kurasikirwa nesimba mupombi yemvura. Naizvozvo, simba rinoshanda re pombi rinogara rakaderera pane simba resimba. Kubudirira kunogadzira iyo inoshanda degree rekushandurwa kwesimba kweshoko remvura, uye izita rakakosha hunyanzvi uye ehupfumi index ye pombi yemvura.
η = pe / p × 100%
3. Shaft Simba
Inozivikanwa seSimba rekuisa. Inoreva simba rakawanikwa neiyo pombi shaft kubva kumuchina wemagetsi, iyo inoratidzwa naP.
PSHAFT SIMBA = PE / IC = ρGQH / 1000 / η (KW)
4. Kufananidza Simba
Inoreva simba resimba remushini rine mhindu ine pombi yemvura, iyo inomiririrwa naP.
P (kufananidza simba) ≥ (1.1-1.2) PTIFT SIMBA
5.Roti kumhanya
Inoreva huwandu hwenhamba yekuchinja paminiti yemubatanidzwa wemvura yemvura, iyo inomiririrwa na n. Ndiyo unit r / min.
