Isingeniso semigomo yePomp evamile (2) - Ukusebenza kahle + motor

isivinini samandla
1. Amandla asebenzayo:Owaziwa nangokuthi amandla okukhipha. Kubhekisa emandleni atholwe ngu
uketshezi lugeleza ngempompo yamanzi ngesikhathi seyunithi ukusuka emanzini
Pump.

Pe = ρ gqh / 1000 (kW)

ρ - Ubuningi boketshezi olulethwa yiPump (kg / M3)
γ - Isisindo soketshezi esilethwa yiPump (N / M3)
Q - Ukugeleza kwePump (M3 / s)
H - Pump Head (m)
G - Ukusheshisa kwamandla adonsela phansi (M / S2).

I-OreFiko
Kubhekiswa ngamaphesenti wesilinganiso samandla asebenzayo wepompo emandleni aseshadweni, avezwe yi-η. Akunakwenzeka kuwo wonke amandla shaft adluliselwe ku-ketshezi, futhi kukhona ukulahleka kwamandla ephampu lamanzi. Ngakho-ke, amandla asebenzayo ephampu ahlala engaphansi kwamandla shaft. Ukusebenza kahle kuphawula izinga elisebenzayo lokuguqulwa kwamandla kwepompo yamanzi, futhi kuyinkomba ebalulekile yezobuchwepheshe nezomnotho yepompo yamanzi.

I-η = PE / P × 100%

3. Amandla Shaft
Owaziwa nangokuthi amandla okufaka. Kubhekiswa emandleni atholakala nge-pump shaft emshinini wamandla, okuthiwa ngu-P.

I-PSHAFT Power = PE / η = ρGQH / 1000 / η (kw)

4. Ukuqondanisa amandla
Kubhekiswa emandleni omshini wamandla ahambelana nepompo yamanzi, emelelwa ngu-P.

P (amandla afanayo) ≥ (1.1-1.2) Amandla we-PSHAFT

Ijubane le-5.Rerotation
Kubhekiswa kwinani lokuguqulwa ngomzuzu we-impeller yepompo yamanzi, emelelwa ngu-n. Yiyunithi r / min.
