Intshayelelo kwimigaqo eqhelekileyo yepompo (2) - ukusebenza kakuhle + imoto

isantya samandla
1. Amandla Asebenzayo:Ikwabizwa ngokuba ngamandla okukhupha. Ibhekisa kumandla afunyenwe yi
ulwelo oluhamba ngepompo yamanzi ngexesha elinye ukusuka emanzini
impompo.

I-Pe=ρ GQH/1000 (KW)

ρ——Ubuninzi bolwelo oluziswa yipompo (kg/m3)
γ——Ubunzima bolwelo oluziswa yipompo （N/m3）
Q——Ukuhamba kwepompo (m3/s)
H——Intloko yepompo （m)
g——Ukukhawulezisa umxhuzulane (m/s2).

2. Ukusebenza kakuhle
Ibhekisa kwipesenti yomlinganiselo wamandla asebenzayo epompo kumandla eshaft, echazwa yi-η. Akunakwenzeka ukuba onke amandla eshaft adluliselwe kulwelo, kwaye kukho ukulahleka kwamandla kwipompo yamanzi. Ke ngoko, amandla asebenzayo epompo ahlala engaphantsi kwamandla eshaft. Ukusebenza kakuhle kuphawula inqanaba elisebenzayo lokuguqulwa kwamandla epompo yamanzi, kwaye luphawu olubalulekileyo lobuchwephesha noqoqosho lwepompo yamanzi.

η =Pe/P×100%

3. Amandla eshafti
Ikwabizwa ngokuba ngamandla okufaka. Ibhekisa kumandla afunyenwe yi-pump shaft evela kumatshini wamandla, ochazwa yi-P.

PShaft amandla =Pe/η=ρgQH/1000/η (KW)

4. Amandla okuthelekisa
Ibhekisa kumandla omatshini wamandla ahambelana nepompo yamanzi, emelwe yi-P.

P (Amandla Okufanisa) ≥ (1.1-1.2) Amandla e-PSaft

5. Isantya sokujikeleza
Ibhekisa kwinani leenguqu ngomzuzu we-impeller yepompo yamanzi, emelwa yi-n. Ngaba yiyunithi r/min.
