1. Foromo ea ho bala matla a pompo ea shaft

Sekhahla sa phallo × hlooho × 9.81 × matla a khoheli a khethehileng a mahareng ÷ 3600 ÷ pompo e sebetsang hantle

Phallo yuniti: cubic / hora,

Lift unit: limithara

P=2.73HQ/η,

Har'a tsona, H ke hlooho ho m, Q ke sekhahla sa phallo ho m3/h, 'me η ke katleho eapompo ea turbine e tebileng e otlolohileng hantle. P ke matla a shaft ho KW. Ke hore, matla a shaft a pompo P=ρgQH/1000η(kw), moo ρ =1000Kg/m3,g=9.8

Karolo ea matla a khoheli a khethehileng ke Kg/m3, tekanyo ea phallo ke m3/h, karolo ea hlooho ke m, 1Kg=9.8 Newtons.

Ebe P=specific gravity*flow*head*9.8 Newton/Kg

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

=9.8 Newton*m/3600 metsotsoana

=Newton*m/367 metsotsoana

=Watts/367

Tlhaloso e ka holimo ke tšimoloho ea yuniti. Foromo e ka holimo ke palo ea matla a metsi. Matla a shaft a arotsoe ka katleho.

Ha re re matla a shaft ke Ne, matla a enjene ke P, 'me K ke coefficient (ho lumellana ka katleho)

Matla a motlakase P=Ne*K (K e na le litekanyetso tse fapaneng ha Ne e fapane, bona tafole e ka tlase)

Ne≤22 K=1.25

2. Mokhoa oa ho bala oa matla a pompo ea slurry

Sekhahla sa phallo Q M3/H

Phahamisa H m H2O

Katleho n%

Slurry density A KG/M3

Matla a shaft N KW

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

Matla a motlakase a boetse a hloka ho nahana ka katleho ea phetisetso le ntlha ea polokeho. Ka kakaretso, khokahanyo e tobileng e nkoa e le 1, lebanta le nkoa e le 0.96, 'me ntlha ea tšireletso ke 1.2.

3. Katleho ea Pompo le Foromo ea eona ea Palo

E bua ka karo-karolelano ea matla a sebetsang a pompo ea turbine e tebileng e otlolohileng hantle ho matla a shaft. η=Pe/P

Hangata matla a pompo a bua ka matla a ho kenya, ke hore, matla a fetisitsoeng ho tloha ho moetapele ea ka sehloohong ho ea ho pompo ea pompo, kahoo e boetse e bitsoa matla a shaft mme e emeloa ke P.

Matla a sebetsang ke: sehlahisoa sa hlooho ea pompo, sekhahla sa phallo ea boima le ho potlakisa matla a khoheli.

Pe=ρg QH (W) kapa Pe=γQH/1000 (KW)

ρ: Boima ba metsi a tsamaisoang ke pompo (kg/m3)

γ: Matla a khoheli a mokelikeli o tsamaisoang ke pompo γ=ρg (N/m3)

g: ho potlakisa ka lebaka la matla a khoheli (m/s)

Sekhahla sa phallo ea boima Qm=ρQ (t/h kapa kg/s)

4. Kenyelletso ea Katleho ea Lipompo

Ho sebetsa hantle ha pompo ke eng? Foromo ke efe?

Karabo: E bua ka karo-karolelano ea matla a sebetsang a pompo ho matla a shaft. η=Pe/P

Matla a seliba se tebileng pompo ea turbine e otlolohileng hangata e bua ka matla a ho kenya, ke hore, matla a fetisoang ho tloha ho moetapele oa pele ho ea ho pompo ea pompo, kahoo e boetse e bitsoa matla a shaft mme e emeloa ke P.

Matla a sebetsang ke: sehlahisoa sa hlooho ea pompo, sekhahla sa phallo ea boima le ho potlakisa matla a khoheli.

Pe=ρg QH W kapa Pe=γQH/1000 (KW)

ρ: Boima ba metsi a tsamaisoang ke pompo (kg/m3)

γ: Matla a khoheli a mokelikeli o tsamaisoang ke pompo γ=ρg (N/m3)

g: ho potlakisa ka lebaka la matla a khoheli (m/s)
