1. Khatello ea Phallo ea Pompe

Khatello ea ho tsoa ha pompo e tebileng ea turbine e emeng hantle e bua ka kakaretso ea matla a khatello (unit: MPa) ea mokelikeli o romelloang ka mor'a ho feta pompong ea metsi. Ke pontšo ea bohlokoa ea hore na pompo e ka phetha mosebetsi oa ho tsamaisa metsi. Khatello ea ho ntša metsi ea pompo ea metsi e ka ama hore na tlhahiso ea mosebedisi e ka tsoela pele ka mokhoa o tloaelehileng. Ka hona, khatello ea ho ntša metsi ea pompo ea metsi e entsoe le ho khethoa ho latela litlhoko tsa ts'ebetso ea sebele.

Ho ipapisitsoe le litlhoko tsa ts'ebetso ea tlhahiso le litlhoko tsa semela sa tlhahiso, khatello ea ho lahla haholo-holo e na le mekhoa e latelang ea polelo.

1.Tlhaloso e tloaelehileng ea khatello: Khatello e hlokahalang ea ho ntša pompo ha khoebo e sebetsa tlas'a maemo a tloaelehileng a ho sebetsa.

2.Maximum a hlokehang khatello ea ho lahla: Ha maemo a tlhahiso ea khoebo a fetoha, maemo a sebetsang a ka 'nang a hlaha a itšetlehile ka khatello e hlokahalang ea ho ntša pompo.

3. Khatello e lekantsoeng ea ho qhala: Khatello ea ho ntša metsi e boletsoeng le ho tiisetsoa hore e tla finyelloa ke moetsi oa pompo. Khatello e lekantsoeng ea ho tsoa e lokela ho lekana kapa e kholo ho feta khatello e tloaelehileng ea ts'ebetso. Bakeng sa lipompo tsa vane e lokela ho ba khatello ea ho ntša metsi ka phallo e phahameng.

4. Khatello e phahameng e lumelletsoeng ea ho ntša khatello: Bophahamo bo phahameng bo lumelletsoeng ba khatello ea pompo bo khethoa ke moetsi oa pompo ho latela ts'ebetso ea pompo, matla a sebopeho, matla a pele a tsamaisang, joalo-joalo. khatello e phahameng e hlokehang ea ho ntša khatello, empa e lokela ho ba tlase ho feta khatello e phahameng e lumelletsoeng ea ho sebetsa ea likarolo tsa khatello ea pompo.

2. Hlooho ea pompo H

Hlooho ea pompo ea metsi e bolela matla a fumanoang ka boima ba yuniti ea mokelikeli o fetang pompo ea turbine e tebileng e otlolohileng hantle. E hlalositsoe ke H, yuniti ke m, e leng bophahamo ba kholomo ea mokelikeli oa mokelikeli o ntšitsoeng.

Matla a sebetsang a fumanoang ka mor'a khatello ea yuniti ea metsi a feta pompong, e tsejoang hape e le hlooho eohle kapa hlooho e feletseng. Re ka boela ra bua ka phapano ea matla lipakeng tsa mokelikeli sebakeng sa ho tsoa le se kenang pompong ea metsi. Empa e tlameha ho hlokomeloa: e amana feela le ts'ebetso ea pompo ka boeona 'me ha e amane le liphaephe tsa ho kenya le ho tsoa. Karolo ea lift ke bophahamo ba kholomo ea metsi N·m kapa m.

Bakeng sa lipompo tsa khatello e phahameng, phapang ea khatello pakeng tsa phallo ea pompo le ho kena (p2-P1) ka linako tse ling e hakanngoa ho emela boholo ba phahamiso. Ka nako ena, lift H e ka hlalosoa ka tsela e latelang:

Ka foromo, P1——khatello ea phallo ea pompo, Pa;

P2 ke khatello e kenang ea pompo, Pa;

p——boima ba metsi, lik’hilograma/m3;

g——matla a khoheli, m/S2.

Phahamisa ke karolo ea bohlokoa ea ts'ebetso ea pompo ea metsi, e thehiloeng litlhoko tsa mekhoa ea peterole le lik'hemik'hale le litlhoko tsa moetsi oa pompo.

1. Hlooho e tloaelehileng ea ho sebetsa: Hlooho ea pompo e khethiloeng ke khatello ea ho ntša metsi le khatello ea ho hula ea pompo tlas'a maemo a tloaelehileng a tlhahiso ea khoebo.

2. Phahamiso e phahameng e hlokahalang ke ho phahamisa pompo ha khatello e phahameng e hlokahalang ea ho ntša (khatello ea ho hula e lula e sa fetohe) e fetoha ha maemo a tlhahiso ea khoebo a fetoha.

3. Hlooho e lekantsoeng Hlooho e lekantsoeng ke hlooho ea pompo ea metsi tlas'a bophara ba impeller e lekantsoeng, lebelo le lekantsoeng, ho hula ho lekanngoa le khatello ea ho ntša metsi. Ke hlooho e khethiloeng le ho tiisetsoa ke moetsi oa pompo, 'me boleng bona ba hlooho bo lokela ho lekana kapa bo boholo ho feta hlooho e tloaelehileng ea ho sebetsa. Ka kakaretso, boleng ba eona bo lekana le bophahamo bo phahameng bo hlokahalang.

4. Hlooho e koalang Hlooho e koalang ke hlooho ha sekhahla sa phallo ea pompo ea metsi e le zero. Ke tekanyo e phahameng ka ho fetisisa ea ho phahamisa pompo ea metsi. Ka kakaretso, khatello ea ho ntša tlas'a phahamiso ena e etsa hore ho be le khatello e phahameng e lumelletsoeng ea ho sebetsa ea likarolo tsa khatello tse kang 'mele oa pompo.
