U ka bala hlooho ea pompo joang?
Karolong ea rona ea bohlokoa e le bahlahisi ba Hydraulic, re tseba palo e kholo ea lintho tse fapaneng tse hlokang ho nkuoa ha re khetha pompo e nepahetseng. Morero oa sengoloa sena sa pele ke ho qala ho hlakisa palo e kholo ea matšoao a mahlale a Hydraulic pompo ea pompa ".
Hlooho ea Pump ke eng?
Hlooho hlooho, hangata e bitsoa hlooho e felletseng ea hlooho kapa e matla ea matla (tdh), e emela matla a felletseng a banngoeng ke metsi ka pompo. E khetholla motsoako oa matla a matla le matla a pompo ea pompo ho feta bophahamo ba ho phahamisa hloohong. Mohlala o hlakileng ke oa phala e otlolohileng e ntseng e phahama ka ho toba ho tsoa ka kotloloho e le haufi. Mokelikeli o tla phuthoa ka lipeipi tse 5 ho tloha sethaleng sa ho seha ka sekhukhu ka pompo e nang le hlooho ea limithara tse 5. Hlooho ea pompo e hokahane ka thata ka sekhahla sa ho phalla. Tekanyo e phahameng ea ho phalla ea pompo, tlase ho theola hlooho. Hlooho ea pompo ea bohlokoa e bohlokoa hobane e thusa lienjiniere ho lekola ts'ebetso ea pompa, khetha pompa e nepahetseng bakeng sa ts'ebeliso e khethehileng, 'me e rarollotsoeng tsamaiso e tloaelehileng ea mokelikeli.
Likarolo tsa hlooho ea pompo
Ho utloisisa lipalo tsa pompo ea pompo, ho bohlokoa hore li senye likarolo tse kenyang hloohong eohle:
Hlooho ea Statistra (HS): Hlooho ea Static ke sebaka se otlolohileng pakeng tsa suction ea pompo le ho theola lintlha. E fana ka tlaleho ea liphetoho tse ka bang teng ka lebaka la ho phahama. Haeba ntlha ea ho tsoaloa e phahame haholo ho feta ntlha ea suctional, hlooho ea lipalo e ntle, 'me haeba e le tlase, ha e le tlase e fosahetse.
Heard Head (Hv): Hlooho ea Velocity ke matla a Kinetic a hlahisoang ke metsi ha a ntse a feta liphaephe. Ho latela velocity ea mokelikeli 'me e baloa ho sebelisa equation:
Hv=V^ 2 / 2G
Moo:
- Hv= Hlooho ea li-veelocity (Metres)
- V= Lijo tsa phallo ea mokelikeli (m / s)
- g= Ho potlakisa ka lebaka la matla a khoheli (9.81 m / s²)
Khatello hlooho (HP): Hlooho ea khatello e emela matla a eketsoeng mokelikeli ke pompa ea ho hlola tahlehelo ea khatello ea tsamaiso tsamaisong. E ka baloa ho sebelisa equation ea Bernoulli:
Hp=Pd-PS / ρg
Moo:
- Hp= Hlooho ea khatello (limithara)
- Pd= Khatello ho Poincharge Point (PA)
- Ps= Khatello ho Point Point (PA)
- ρ= Phobiso ea lijo (kg / m³)
- g= Ho potlakisa ka lebaka la matla a khoheli (9.81 m / s²)
Lihlooho tsa likhohlano (HF): Litlaloana tsa hlooho tsa likhohlano bakeng sa tahlehelo ea matla ka lebaka la tatso ea pompong le li-cookiti tsa sekepe tsamaisong. E ka baloa ho sebelisa tekanyetso ea Darcy-Weisbaa:
Hf=FLQ ^2/D^2g
Moo:
- Hf= Lihlooho tsa likhohlano (Metres)
- f= Darcy Fricce Imagement ea litlolo (e se na moelelo)
- L= Bolelele ba phala (limithara)
- Q= Sekhahla sa ho phalla (m³ / s)
- D= Bophara ba phala (limithara)
- g= Ho potlakisa ka lebaka la matla a khoheli (9.81 m / s²)
Equation ea lihlooho
Lihlooho tsohle (H) ea sistimi ea pompo ke kakaretso ea likarolo tsena tsohle:
H=Hs+Hv+Hp+Hf
Ho utloisisa equation ena ho lumella baenjiniere ho sheba litsamaiso tse sebetsang hantle ka ho nahana ka lintlha tse kang phallo e hlokahalang, phapang ea liphapang le ho hatella.
Likopo tsa lipalo tsa hlooho ea pompo
Pompo ea pompo: Baenjiniere ba sebelisa lipalo tsa pompo ho khetha pompo e loketseng bakeng sa ts'ebeliso e itseng. Ka ho khetha hlooho e hlokahalang, ba ka khetha pompo e ka fihlelang le seo se ka fihlelang le litlhoko tsena hantle.
Moralo oa tsamaiso: Lipalo tsa hlooho tsa pompo ke tsa bohlokoa ho qapa mekhoa ea ho tsamaisa mokelikeli. Baenjiniere ba ka khona ho etsa liphaephe le ho khetha lijo tse loketseng ho fokotsa tahlehelo ea likhohlano le ho holisa ts'ebetso ea sistimi.
Ts'ebetso ea Matla: Pompo ea pompo e thusa ho ntlafatsa ts'ebetso ea pomm bakeng sa ts'ebetso 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 ka mor'a nako ho ka thusa ho bona liphetoho ts'ebetsong ea sistimi, ho bonts'a tlhokahalo ea ho lokise kapa ho tsoa ho bana.
Mohlala oa ho bala: ho khetholla hlooho ea pompo ea pompo
Ho hlakisa mohopolo oa lipalo tsa pompo, a re hlahlobeng boemo bo bonolo bo lekaneng pompo ea metsi e sebelisitsoeng ho nosetsa. Boemong bona, re batla ho tseba hore hlooho e felletseng e hlokahalang bakeng sa phetiso ea metsi ho tsoa ho ea pohlamong ho ea tšimong.
Li-parameters:
Phapang ea bophahamo (ΔH): Sebaka se otlolohileng ho tloha boemong ba metsi ho ea lebaleng boemong bo phahameng ka ho fetisisa tšimong ea nosetso ke limithara tse 20.
Tahlehelo ea hlooho ea likhohlano (HF): Tahlehelo ea likhohlano ka lebaka la liphaephe, litekete, le likarolo tse ling ka nako ea likarolo tse 5.
Heard Head (Hv): Ho boloka phallo e tsitsitseng, hlooho e itseng ea millocity e hlokahala.
Khatello hlooho (HP): Hlooho e eketsehileng ea hlooho, joalo ka ho hlola mohoebi ea khatello, o 3 le limithara.
Lipalo:
Hlooho ea pompo ea pompo (h) e hlokahalang e ka baloa ho sebelisa equation e latelang:
Kakaretso ea pompo ea pompo ea pompo e felletseng (H) = Phapang ea Phapang
H = limithara tse 20 + limithara tse 2 + limithara tse peli + 3 mithara
H = limithara tse 30
Mohlala ona, hlooho ea pompo e hlokoa bakeng sa sistimi ea nosetso ke limithara tse 30. Sena se bolela hore pompo e tlameha ho fana ka matla a lekaneng ho phahamisa metsi a 20, ho hlola tahlehelo ea likhohlano, boloka khatello e itseng moo ho hlokahalang.
Kutloisiso le ho bala ka nepo hlooho ea pompo e bohlokoa bakeng sa ho khetha pompo e lekantsoeng e hlophisitsoeng ho fihlela sekhahla se pharalletseng setulong se lekanang.
Nka fumana sebaka sa hlooho sa pompo hokae?
Letšoao la hlooho la pompo le teng ebile le ka fumanoa hoMaqephe a dataea lihlahisoa tsohle tsa sehlooho. Ho fumana tlhaiso-leseling e ngata ka data ea mahlale ea lipompo tsa rona, ka kopo ikopanye le sehlopha sa mahlale le sa thekiso.
