1. Pump shaft mana tātai tātai

Rere rere × pane × 9.81 × taumahatanga tauwhāiti waenga ÷ 3600 ÷ te pai o te papu

Wae rere: pūtoru/haora,

Wae hiki: mita

P=2.73HQ/η,

poutū multistage turbine papu pukapuka

I roto ia ratou, ko H te upoko i roto i te m, ko Q te rerenga rere i roto i te m3/h, ko te η te kaha o tepuna hohonu poutū turbine papu. Ko te P te mana o te rakau i roto i te KW. Arā, ko te kaha o te pū o te papu P=ρgQH/1000η(kw), kei hea ρ =1000Kg/m3,g=9.8

Ko te waeine o te taumahatanga motuhake ko Kg/m3, ko te waeine rere he m3/h, ko te mahunga he m, 1Kg=9.8 Newtons

Katahi ka P=taimaha motuhake*rere*upoko*9.8 Newton/Kg

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

=9.8 Newton*m/3600 hēkona

=Newton*m/367 hēkona

= Watts/367

Ko te takenga o runga ake nei ko te takenga mai o te waeine. Ko te tauira i runga ake nei ko te tataunga o te mana wai. Ko te kaha o te rakau ka wehewehea e te kaha.

Mehemea ko te kaha o te rakau ko Ne, ko te mana motopaika ko P, ko K te whakarea (tauutuutu o te pai)

Te mana motopaika P=Ne*K (He rereke nga uara o K ina rereke a Ne, tirohia te ripanga i raro nei)

Ne≤22 K=1.25

  rua tekau ma rua

55

2. Tātai tātai o te mana slurry papu rakau

Rere rere Q M3/H

Hiki H m H2O

Te kaha n %

Kiato puwhero A KG/M3

Te kaha o te rakau N KW

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

Me whai whakaaro ano te mana motopaika ki te pai o te tuku me te take haumaru. Ko te tikanga, ko te hononga tika ka tangohia hei 1, ka tangohia te whitiki hei 0.96, ko te take haumaru ko te 1.2.

3. Te Pump Efficiency and its Calculation Formula

E tohu ana ki te ōwehenga o te mana whai hua o te puna hohonu poutū turbine papu ki te mana o te poro. η=Pe/P

Ko te mana o te papu te tikanga e pa ana ki te mana whakauru, ara, te mana ka tukuna mai i te kaikawe tuatahi ki te papa papu, no reira ka kiia hoki ko te mana toka ka tohuhia e te P.

Ko te mana whai hua ko: ko te hua o te upoko papu, te tere o te rere papatipu me te tere o te kaha.

Pe=ρg QH (W) ranei Pe=γQH/1000 (KW)

ρ: Kiato o te wai e kawea ana e te papu (kg/m3)

γ: Te kaha o te wai e kawea ana e te papu γ=ρg (N/m3)

g: whakaterenga na te kaha (m/s)

Rere rere papatipu Qm=ρQ (t/h, kg/s rānei)

4. Whakataki ki te Pai o nga Pumps

He aha te mahi papu? He aha te tātai?

Whakautu: E pa ana ki te tauwehenga o te mana whai hua o te papu ki te mana o te rakau. η=Pe/P

Te mana o te puna hohonu papu turbine poutū Ko te tikanga e pa ana ki te mana whakauru, ara, te mana ka tukuna mai i te kaikawe tuatahi ki te papa papu, no reira ka kiia hoki ko te mana o te rakau ka tohuhia e te P.

Ko te mana whai hua ko: ko te hua o te upoko papu, te tere o te rere papatipu me te tere o te kaha.

Pe=ρg QH W, Pe=γQH/1000 (KW)

ρ: Kiato o te wai e kawea ana e te papu (kg/m3)

γ: Te kaha o te wai e kawea ana e te papu γ=ρg (N/m3)

g: whakaterenga na te kaha (m/s)

Rere papatipu Qm=ρQ t/h, kg/s rānei
