Hlooho, phallo le matla ke likarolo tsa bohlokoa tsa ho hlahloba ts'ebetso ea pompo:

1.Sekhahla sa phallo

Sekhahla sa phallo ea pompo se boetse se bitsoa bophahamo ba phallo ea metsi.

E bolela palo ea metsi a fanoang ke pompo ka nako ea yuniti. E emetsoe ke letšoao Q, yuniti ea eona ke lithara/ea bobeli, li-cubic meter/ea bobeli, cubic meter/hora.

2.Hlooho

Hlooho ea pompo e bua ka bophahamo boo pompo e ka pompang metsi ka eona, hangata e emeloa ke letšoao la H, 'me karolo ea eona ke mithara.

Hlooho ea pompo e monyang habeli e thehiloe bohareng ba impeller mme e na le likarolo tse peli. Bophahamo bo otlolohileng ho tloha bohareng ba pompo ea pompo ho ea holim'a metsi a mohloli oa metsi, ke hore, bophahamo boo pompo e ka monyang metsi ho eona, bo bitsoa "suction lift", e bitsoang "suction lift"; bophahamo bo otlolohileng ho tloha bohareng ba pompo ea pompo ho ea holim'a metsi a letamo la ho tsoa, ​​​​ke hore, pompo ea metsi e ka hatella metsi holimo Bophahamo bo bitsoa hlooho ea khatello ea metsi, e bitsoang khatello ea khatello. Ke hore, hlooho ea pompo ea metsi = hlooho ea ho hula metsi + hlooho ea khatello ea metsi. Ho lokela ho totobatsoa hore hlooho e tšoailoeng holim'a nameplate e bua ka hlooho eo pompo ea metsi ka boeona e ka e hlahisang, 'me ha e kenyeletse hlooho ea tahlehelo e bakoang ke ho hanyetsa ho ferekanngoa ha phallo ea metsi ea pipeline. Ha u khetha pompo ea metsi, ela hloko hore u se ke ua e hlokomoloha. Ho seng joalo, metsi a ke ke a pompeloa.

3 Matla

Palo ea mosebetsi o etsoang ke mochini ka nako ea yuniti e bitsoa matla.

Hangata e emeloa ke letšoao la N. Lihlopha tse sebelisoang ka tloaelo ke: kilogram m / s, kilowatt, horsepower. Hangata motlakase oa motlakase oa motlakase o hlahisoa ka kilowatts; yuniti ea matla ea enjene ea disele kapa enjene ea peterole e hlahisoa ka matla a lipere. Matla a fetisitsoeng ke mochine oa matla ho pompo ea pompo a bitsoa matla a shaft, a ka utloisisoang e le matla a ho kenya pompong. Ka kakaretso, matla a pompo a bolela matla a shaft. Ka lebaka la khanyetso e tsitsitseng ea ho beha le ho paka; khohlano e teng pakeng tsa ntho e susumetsang le metsi ha e potoloha; the vortex ea phallo ea metsi pompong, lekhalo backflow, inlet le outlet, le phello ea molomo, joalo-joalo E tlameha ho ja karolo ea matla, kahoo pompo e ke ke ea fetola ka ho feletseng matla a kenyang a mochine oa matla ho kena. matla a sebetsang, 'me ho tlameha ho ba le tahlehelo ea matla, ke hore, kakaretso ea matla a sebetsang a pompo le tahlehelo ea matla pompong ke matla a shaft a pompo.

Hlooho ea pompo, mokhoa oa ho bala oa phallo:

Hlooho ea pompo H=32 e bolela'ng?

Hlooho H = 32 e bolela hore mochine ona o ka phahamisa metsi ho fihlela ho limithara tse 32

Phallo = sebaka se pota-potileng * lebelo la phallo Lebelo la phallo le hloka ho lekanyetsoa ke uena: stopwatch

Khakanyo ea ho phahamisa pompo:

Hlooho ea pompo ha e amane le matla, e amana le bophara ba pompo ea pompo le palo ea mekhahlelo ea impeller. Pompo e nang le matla a tšoanang e ka 'na ea e-ba le hlooho ea limithara tse makholo, empa tekanyo ea phallo e ka' na ea e-ba lisekoere-mithara tse seng kae feela, kapa hlooho e ka 'na ea e-ba limithara tse seng kae feela, empa tekanyo ea phallo e ka ba ho fihlela ho 100 metres. Litsela tse makholo. Molao o akaretsang ke hore tlas'a matla a tšoanang, tekanyo ea phallo ea hlooho e phahameng e fokotsehile, 'me tekanyo ea ho phalla ha hlooho e tlaase e kholo. Ha ho na mokhoa o tloaelehileng oa ho bala ho fumana hlooho, 'me ho itšetlehile ka maemo a hau a tšebeliso le mohlala oa pompo ho tloha fekthering. E ka baloa ho latela tekanyo ea khatello ea pompo. Haeba phallo ea pompo e le 1MPa (10kg/cm2), hlooho e ka ba limithara tse 100, empa tšusumetso ea khatello ea ho hula le eona e tlameha ho nkoa. Bakeng sa pompo ea centrifugal, e na le lihlooho tse tharo: hlooho ea sebele ea ho hula, hlooho ea sebele ea khatello ea metsi le hlooho ea sebele. Haeba e sa hlalosoa, ka kakaretso ho lumeloa hore hlooho e bua ka phapang ea bophahamo pakeng tsa libaka tse peli tsa metsi.

Seo re buang ka sona mona ke sebopeho sa khanyetso sa sistimi ea metsi a batang ea moea o koetsoeng, hobane sistimi ena ke sistimi e sebelisoang hangata.

Mohlala: Ho hakanya hlooho ea pompo e hulang habeli

Ho ea ka se boletsoeng ka holimo, tahlehelo ea khatello ea tsamaiso ea metsi a moea oa mohaho o phahameng o ka bang bolelele ba 100m e ka hakanngoa, ke hore, ho phahama ho hlokahalang ke pompo ea metsi e potolohang:

1. Chiller resistance: nka 80 kPa (8m kholomo ea metsi);

2. Ho hanyetsa liphaephe: Nka khanyetso ea sesebelisoa sa decontamination, pokello ea metsi, karohano ea metsi le pipeline ka kamoreng ea sehatsetsing e le 50 kPa; nka bolelele ba phaephe ka lehlakoreng la phetisetso le kabo e le 300m le khanyetso e khethehileng ea likhohlano ea 200 Pa/m, ebe The friction resistance ke 300*200=60000 Pa=60 kPa; haeba khanyetso ea sebaka ka lehlakoreng la phetisetso le kabo ke 50% ea khanyetso ea likhohlano, khanyetso ea lehae ke 60 kPa * 0.5 = 30 kPa; kakaretso ea khanyetso ea pipeline ea tsamaiso ke 50 kPa+ 60 kPa+30 kPa = 140 kPa (kholomo ea metsi a 14m);

3. Ho hanyetsa ha mochine oa mochine oa mocheso oa moea: ho hanyetsa ha mochine o kopantsoeng oa moea o kopantsoeng ka kakaretso o moholo ho feta oa fan coil unit, kahoo khanyetso ea pele ke 45 kPa (4.5 kholomo ea metsi); 4. Ho hanyetsa ha valve e laolang litsela tse peli: 40 kPa (0.4 kholomo ea metsi) .

5. Ka hona, kakaretso ea khanyetso ea karolo e 'ngoe le e' ngoe ea tsamaiso ea metsi ke: 80 kPa + 140kPa + 45 kPa + 40 kPa = 305 kPa (30.5m kholomo ea metsi)

6. Hlooho ea pompo ea ho hula habeli: Ho nka ntlha ea tšireletso ea 10%, hlooho H = 30.5m * 1.1 = 33.55m.

Ho ea ka liphetho tsa likhakanyo tse ka holimo, mefuta e mengata ea tahlehelo ea khatello ea tsamaiso ea metsi a futhumatsang moea ea mehaho ea sekala se tšoanang e ka utloisisoa. Ka ho khetheha, ho lokela ho thibeloa hore tahlehelo ea khatello ea tsamaiso e kholo haholo ka lebaka la likhakanyo tse sa baloang le tse tsitsitseng haholo, 'me hlooho ea pompo ea metsi e khethoa e le khōlō haholo. Se bakang ho senyeha ha matla.
