1. Ifomula yokubala amandla e-pump shaft

Izinga lokugeleza × ikhanda × 9.81 × amandla adonsela phansi athize amaphakathi ÷ 3600 ÷ ukusebenza kahle kwepompo

Iyunithi yokugeleza: cubic / ihora,

Iyunithi yokuphakamisa: amamitha

P=2.73HQ/η,

Phakathi kwazo, u-H uyinhloko ku-m, u-Q izinga lokugeleza ku-m3/h, futhi u-η ukusebenza kahle kwe-iphampu ye-turbine ejulile kahle. I-P ingamandla e-shaft ku-KW. Okusho ukuthi, amandla we-shaft wepompo P=ρgQH/1000η(kw), lapho ρ =1000Kg/m3,g=9.8

Iyunithi ye-gravity ethize yi-Kg/m3, iyunithi yokugeleza yi-m3/h, iyunithi yekhanda ngu-m, 1Kg=9.8 Newtons

Bese u-P=i-gravity ethize*ukugeleza*ikhanda*9.8 Newton/Kg

=Kg/m3*m3/h*m*9.8 Newton/Kg

=9.8 Newton*m/3600 imizuzwana

=I-Newton*m/367 imizuzwana

=Watts/367

Okuphuma ngenhla kuwumsuka weyunithi. Ifomula engenhla iwukubalwa kwamandla amanzi. Amandla we-shaft ahlukaniswe ukusebenza kahle.

Ake sithi amandla e-shaft athi Ne, amandla e-motor angu-P, futhi u-K yi-coefficient (okuhambisana nokusebenza kahle)

Amandla emoto P=Ne*K (K inamanani ahlukene uma i-Ne ihlukile, bheka ithebula elingezansi)

Ne≤22 K=1.25

2. Ifomula yokubala yamandla we-slurry futha shaft

Izinga lokugeleza Q M3/H

Phakamisa i-H m H2O

Ukusebenza kahle n%

Ukuminyana kwe-slurry A KG/M3

Amandla kashaft N KW

N=H*Q*A*g/(n*3600)

Amandla emoto nawo adinga ukucabangela ukusebenza kahle kokudlulisela kanye nesici sokuphepha. Ngokuvamile, ukuxhumana okuqondile kuthathwa njenge-1, ibhande lithathwa njenge-0.96, futhi isici sokuphepha yi-1.2.

3. Ukuphumelela Kwephampu kanye nefomula yayo yokubala

Isho isilinganiso samandla asebenzayo we- iphampu ye-turbine ejulile kahle emandleni eshaft. η=Pe/P

Amandla epompo ngokuvamile abhekisela emandleni okufakwayo, okungukuthi, amandla adluliswa esuka ku-prime mover aye ku-pump shaft, ngakho-ke abizwa nangokuthi amandla e-shaft futhi amelelwa ngu-P.

Amandla asebenzayo yilokhu: umkhiqizo wekhanda lephampu, izinga lokugeleza okukhulu kanye nokusheshisa amandla adonsela phansi.

I-Pe=ρg QH (W) noma i-Pe=γQH/1000 (KW)

ρ: Ukuminyana koketshezi oluthuthwa yiphampu (kg/m3)

γ: Amandla adonsela phansi oketshezi oluthuthwa yiphampu γ=ρg (N/m3)

g: ukusheshisa ngenxa yamandla adonsela phansi (m/s)

Izinga lokugeleza okukhulu Qm=ρQ (t/h noma kg/s)

4. Isingeniso Sempumelelo Yamaphampu

Kuyini ukusebenza kahle kwephampu? Ithini ifomula?

Impendulo: Ibhekisela esilinganisweni samandla asebenzayo wepompo kumandla we-shaft. η=Pe/P

Amandla omthombo ojulile iphampu ye-turbine eqondile ngokuvamile ibhekisela emandleni okufakwayo, okungukuthi, amandla adluliswa esuka ku-prime mover kuya ku-pump shaft, ngakho-ke ibizwa nangokuthi amandla e-shaft futhi imelwe ngu-P.

Amandla asebenzayo yilokhu: umkhiqizo wekhanda lephampu, izinga lokugeleza okukhulu kanye nokusheshisa amandla adonsela phansi.

I-Pe=ρg QH W noma i-Pe=γQH/1000 (KW)

ρ: Ukuminyana koketshezi oluthuthwa yiphampu (kg/m3)

γ: Amandla adonsela phansi oketshezi oluthuthwa yiphampu γ=ρg (N/m3)

g: ukusheshisa ngenxa yamandla adonsela phansi (m/s)

Ukugeleza kwenqwaba Qm=ρQ t/h noma kg/s
