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

isantya samandla
1. Amandla asebenzayo:Ikwaziwa njengamandla emveliso.Ibhekisa kumandla afunyenwe yi
ulwelo oluqukuqela kwimpompo yamanzi ngeyunithi yexesha ukusuka emanzini
impompo .

Pe=ρ GQH/1000 (KW)

ρ——Ukuxinana kolwelo oluhanjiswa ngempompo (kg/m3)
γ——Ubunzima bolwelo buhanjiswa ngempompo (N/m3)
Q——Ukuhamba kwempompo (m3/s)
H——Intloko yempompo (m)
g——Ukukhawuleza komxhuzulane (m/s2).

2.Ubuchule
Ibhekisela kwipesenti yomlinganiselo wamandla asebenzayo wempompo kumandla we-shaft, echazwe ngu-η.Akunakwenzeka ukuba onke amandla e-shaft adluliselwe kulwelo, kwaye kukho ukulahleka kwamandla kwimpompo yamanzi.Ngoko ke, amandla asebenzayo epompo ahlala engaphantsi kwamandla e-shaft.Ucikizeko luphawula iqondo elisebenzayo lokuguqulwa kwamandla kwimpompo yamanzi, kwaye luphawu olubalulekileyo lobugcisa noqoqosho lwempompo yamanzi.

η =Pe/P×100%

3. Amandla eshaft
Ikwaziwa njengamandla okufaka.Ibhekisa kumandla afunyenwe ngumphini wempompo kumatshini wamandla, ochazwa nguP.

PShaft amandla =Pe/η=ρgQH/1000/η (KW)

4. Amandla okudibanisa
Ibhekisa kumandla omatshini wamandla ohambelana nempompo yamanzi, emelwe nguP.

P(Amandla oMatanisa)≥(1.1-1.2) PShaft amandla

5.Isantya sokujikeleza
Ibhekisa kwinani leenguqu ngomzuzu we-impeller yempompo yamanzi, emelwe yi-n.Ngaba iyunithi r/min.
