Mokhoa oa ho Bala Hlooho ea Pompo？
Karolong ea rona ea bohlokoa re le bahlahisi ba lipompo tsa hydraulic, re tseba palo e kholo ea lintho tse fetohang tse lokelang ho nahanoa ha ho khethoa pompo e nepahetseng bakeng sa ts'ebeliso e itseng. Morero oa sengoloa sena sa pele ke ho qala ho hlakisa palo e kholo ea matšoao a tekheniki ka har'a bokahohle ba pompo ea hydraulic, ho qala ka paramethara "hlooho ea pompo".
Pompo ea Hlooho ke eng?
Hlooho ea pompo, eo hangata e bitsoang hlooho e felletseng kapa hlooho e felletseng ea matla (TDH), e emela matla a felletseng a fetisetsoang mokelikeling ke pompo. E lekanya motsoako oa matla a khatello le matla a kinetic ao pompo e a fetisetsang mokelikeling ha e ntse e tsamaea tsamaisong. Ka bokhutšoanyane, re ka boela ra hlalosa hlooho e le bophahamo bo phahameng ka ho fetisisa ba ho phahamisa boo pompo e khonang ho bo fetisetsa ho mokelikeli o pompetsoeng. Mohlala o hlakileng ke oa phaephe e otlolohileng e nyolohang ka ho toba ho tsoa mokerong oa phepelo. Mokelikeli o tla pompetsoa ka phaepheng limithara tse 5 ho tloha mokerong oa ho ntša metsi ke pompo e nang le hlooho ea limithara tse 5. Hlooho ea pompo e amana ka tsela e fapaneng le sekhahla sa phallo. Ha sekhahla sa phallo ea pompo se phahame, hlooho e tlase. Ho utloisisa hlooho ea pompo hoa bohlokoa hobane ho thusa baenjiniere ho lekola ts'ebetso ea pompo, ho khetha pompo e nepahetseng bakeng sa ts'ebeliso e fanoeng, le ho rala litsamaiso tse sebetsang hantle tsa ho tsamaisa metsi.
Likarolo tsa Hlooho ea Pompo
Ho utloisisa lipalo tsa hlooho ea pompo, ho bohlokoa ho arola likarolo tse tlatsetsang hloohong eohle:
Hlooho e sa fetoheng (Hs): Hlooho e sa fetoheng ke sebaka se otlolohileng pakeng tsa libaka tsa ho hula le ho ntša pompo. E ikarabella bakeng sa phetoho e ka bang teng ea matla ka lebaka la bophahamo. Haeba ntlha ea ho ntša e phahame ho feta ntlha ea ho hula, hlooho e sa fetoheng e ntle, 'me haeba e le tlase, hlooho e sa fetoheng e mpe.
Hlooho ea Lebelo (Hv): Hlooho ea lebelo ke matla a kinetic a fuoang mokelikeli ha o ntse o tsamaea ka har'a liphaephe. Ho itšetlehile ka lebelo la mokelikeli 'me ho baloa ho sebelisoa equation:
Hv=V^2/2g
Moo:
- Hv= Hlooho ea lebelo (limithara)
- V= Lebelo la mokelikeli (m/s)
- g= Ho potlaka ka lebaka la matla a khoheli (9.81 m/s²)
Hlooho ea Khatello (Hp): Hlooho ea khatello e emela matla a eketsoang mokelikeling ke pompo ho hlola tahlehelo ea khatello tsamaisong. E ka baloa ho sebelisoa equation ea Bernoulli:
Hp=Pd−Ps/ρg
Moo:
- Hp= Hlooho ea khatello (limithara)
- Pd= Kgatelelo sebakeng sa ho ntsha metsi (Pa)
- Ps= Kgatelelo sebakeng sa ho hula (Pa)
- ρ= Bongata ba mokelikeli (kg/m³)
- g= Ho potlaka ka lebaka la matla a khoheli (9.81 m/s²)
Hlooho ea khohlano (Hf): Hlooho ea khohlano e ikarabella bakeng sa tahlehelo ea matla e bakoang ke khohlano ea liphaephe le li-fittings tsamaisong. E ka baloa ho sebelisoa equation ea Darcy-Weisbach:
Hf=fLQ^2/D^2g
Moo:
- Hf= Hlooho ea khohlano (limithara)
- f= Ntlha ea khohlano ea Darcy (e se nang tekanyo)
- L= Bolelele ba phaephe (limithara)
- Q= Sekhahla sa phallo (m³/s)
- D= Bophara ba phaephe (limithara)
- g= Ho potlaka ka lebaka la matla a khoheli (9.81 m/s²)
Kakaretso ea Hlooho ea Sehlooho
Hlooho eohle (H) ea sistimi ea pompo ke kakaretso ea likarolo tsena tsohle:
H=Hs+Hv+Hp+Hf
Ho utloisisa equation ena ho dumella baenjiniere ho rala ditsamaiso tse sebetsang hantle tsa pompo ka ho nahana ka dintlha tse kang sekgahla se hlokahalang sa phallo, boholo ba diphaephe, dipharologanyo tsa bophahamo le ditlhoko tsa kgatello.
Litšebeliso tsa Lipalo tsa Hlooho ea Pompo
Khetho ea Pompo: Baenjiniere ba sebelisa lipalo tsa hlooho ea pompo ho khetha pompo e loketseng ts'ebeliso e itseng. Ka ho fumana kakaretso ea hlooho e hlokahalang, ba ka khetha pompo e ka fihlelang litlhoko tsena ka katleho.
Moralo oa Sistimi: Lipalo tsa hlooho ea pompo li bohlokoa haholo ho raleng litsamaiso tsa lipalangoang tsa metsi. Baenjiniere ba ka lekanya liphaephe le ho khetha lisebelisoa tse loketseng ho fokotsa tahlehelo ea khohlano le ho eketsa katleho ea sistimi.
Tshebetso e Botle ea Matla: Ho utloisisa hlooho ea pompo ho thusa ho ntlafatsa ts'ebetso ea pompo bakeng sa ts'ebeliso e ntle ea matla. Ka ho fokotsa hlooho e sa hlokahaleng, baenjiniere ba ka fokotsa tšebeliso ea matla le litšenyehelo tsa ts'ebetso.
Tlhokomelo le ho rarolla mathata: Ho beha leihlo hlooho ea pompo ha nako e ntse e ea ho ka thusa ho lemoha liphetoho ts'ebetsong ea sistimi, ho bontša tlhoko ea tlhokomelo kapa ho rarolla mathata a kang ho thibela kapa ho lutla.
Mohlala oa Palo: Ho Fumana Kakaretso ea Hlooho ea Pompo
Ho hlalosa mohopolo oa lipalo tsa hlooho ea pompo, ha re nahaneng ka boemo bo nolofalitsoeng bo kenyeletsang pompo ea metsi e sebelisetsoang ho nosetsa. Boemong bona, re batla ho fumana kakaretso ea hlooho ea pompo e hlokahalang bakeng sa kabo e sebetsang hantle ea metsi ho tloha letamo ho ea tšimong.
Liparamente tse Fanoeng:
Phapang ea Phahamo (ΔH): Sebaka se otlolohileng ho tloha boemong ba metsi ka hara letamo ho isa ntlheng e phahameng ka ho fetisisa tšimong ea nosetso ke limithara tse 20.
Tahlehelo ea Hlooho e Ferekaneng (hf): Tahlehelo ea khohlano e bakoang ke liphaephe, li-fitting, le likarolo tse ling tsamaisong e fihla ho limithara tse 5.
Hlooho ea Lebelo (hv): Ho boloka phallo e tsitsitseng, ho hlokahala lebelo le itseng la limithara tse 2.
Hlooho ea Khatello (hp): Hlooho e eketsehileng ea khatello, joalo ka ho hlola molaoli oa khatello, ke limithara tse 3.
Palo:
Kakaretso ea hlooho ea pompo (H) e hlokahalang e ka baloa ho sebelisoa equation e latelang:
Kakaretso ea Hlooho ea Pompo (H) = Phapang ea Phahamo/Hlooho e sa Fetoheng (ΔH)/(hs) + Tahlehelo ea Hlooho e Fetohang (hf) + Hlooho ea Lebelo (hv) + Hlooho ea Khatello (hp)
H = limithara tse 20 + limithara tse 5 + limithara tse 2 + limithara tse 3
H = limithara tse 30
Mohlaleng ona, hlooho yohle ya pompo e hlokahalang bakeng sa sistimi ya nosetso ke dimithara tse 30. Sena se bolela hore pompo e tlameha ho kgona ho fana ka matla a lekaneng ho phahamisa metsi ka dimithara tse 20 ka ho otloloha, ho hlola tahlehelo ya kgohlano, ho boloka lebelo le itseng, le ho fana ka kgatello e eketsehileng ha ho hlokahala.
Ho utloisisa le ho bala ka nepo hlooho yohle ya pompo ho bohlokwa bakeng sa ho kgetha pompo ya boholo bo loketseng ho fihlella sekgahla se lakatsehang sa phallo hloohong e lekanang le yona e hlahang.
Nka fumana setšoantšo sa hlooho ea pompo hokae?
Sesupo sa hlooho ea pompo se teng 'me se ka fumanoa homaqephe a dataea lihlahisoa tsohle tsa rona tsa mantlha. Ho fumana leseli le eketsehileng mabapi le lintlha tsa tekheniki tsa lipompo tsa rona, ka kopo ikopanye le sehlopha sa tekheniki le sa thekiso.
