Tsebo ea motheo ea lipompo tsa lik'hemik'hale

Mokhoa oa ho khetha pompo e loketseng ka ho fetisisa e 'nile ea e-ba ntho e amehang haholo ho batho. Ha ho mohla ho leng bonolo ho uena ho khetha se nepahetsengpompo ea lik'hemik'halehobane lintlha tsena kaofela li bohlokoa: ketsahalo, mecha ea litaba, thepa, joalo-joalo.

Mona re na le kenyelletso e qaqileng ka ho fetisisa ea mefuta e sa tšoaneng ea lipompo, e le ho u fa maikutlo a hlakileng a mofuta ofe oa pompo ea lik'hemik'hale eo u lokelang ho e khetha.

Ho khetha pompo, re tlameha ho qala ho utloisisa le ho tseba melao-motheo ea khetho ea pompo ea lik'hemik'hale. 

1. Mofuta oa pompo o khethiloeng le ts'ebetso e lumellanang le sesebelisoaphallo, hlooho, khatello, mocheso, phallo ea cavitation, suction le mekhoa e meng ea ts'ebetso.

2. E tlameha ho hlakisa litlhoko tsa litšobotsi tse mahareng.

Ha ho tsamaisoa pompo ea mecha ea litaba e ka tukang, e phatlohang e chefo kapa e turang, e hloka tiiso e tšepahalang kapa tšebeliso ea lipompo tse sa lutleng, joalo kapompo ea motlakase ea makenete,diaphragm pompo,pompo ea thebe.

3. Phetiso ea pompo ea media e senyang, ho ts'epahala ha mochini, lerata le tlase, ho thothomela.

4. Moruo o lokela ho ela hloko litšenyehelo tsa thepa, litšenyehelo tsa ts'ebetso, tlhokomelo le litšenyehelo tsa tsamaiso ea litšenyehelo tse tlaase ka ho fetisisa.

5. Liketsahalo tse tloaelehileng, khetho ea pompo ea lik'hemik'hale:

(1) pompo ea centrifugalka lebelo le phahameng, boholo bo nyane, boima bo bobebe, bokhoni bo phahameng, phallo e kholo, sebopeho se bonolo, ha ho na pulsation ea infusion, ts'ebetso e tsitsitseng, ts'ebetso e bonolo le tlhokomelo e bonolo joalo-joalo.

(2) Ho na le litlhoko tsa tekanyo, khetho ea pompo ea metering.

(3) Litlhoko tsa hlooho li phahame haholo, phallo e nyane ebile ha e na phallo e nyane e loketseng phallo e phahameng ea centrifugal motor pump e ka sebelisoang, pompo ea boikhethelo ea ho khutlisa, joalo ka litlhoko tsa cavitation ha li phahame le tsona li ka sebelisa pompo ea vortex.

(4) Hlooho e tlase haholo, phallo e kholo, khetho ea pompo ea phallo ea axial le pompo ea phallo e tsoakiloeng.

(5) Viscosity e mahareng (e kholo ho feta 650 ~ 1000mm2 / s), nahana ka khetho ea pompo ea rotor kapa pompo e lekanang (pompo ea gear, pompo ea screw)

(6) Khase e bohareng ea 75%, sekhahla sa phallo se nyane mme viscosity e ka tlase ho 37.4mm2 / s, khetho ea pompo ea vortex.

Qaleho ya kgafetsa kapapompo ea ho nosetsaliketsahalo tsa tšitiso, lokela ho sebelisa ho intša priming tshebetso ya pompo, joalo kapompo e ikemetseng ea centrifugal,pompo ea ho itšebetsa ea vortex, pompo ea moea (ea motlakase) e inehetseng.

Ho batla likarolo tsa convection ho sebelisa khetho ea pompo e hananang le kutu e ipapisitseng le ts'ebetso e tlameha ho ipapisa le litlhoko tsa phepelo ea metsi le drainage, ho tsoa ho lintlha tse hlano tse lokelang ho nahanoa. 

1. Phallo ke e 'ngoe ea lintlha tsa bohlokoa tsa ts'ebetso ea pompo, e amana ka ho toba le matla a tlhahiso le matla a phetisetso ea sesebelisoa sohle. Joalo ka moralo oa moralo oa Setsi sa Design o ka bala pompo e tloaelehileng, bonyane, mefuta e meraro ea sephethephethe. Khetha pompo, phallo e phahameng e le motheo, ho nahanela phallo e tloaelehileng, ha ho se na phallo e ngata, hangata e lakatseha ka makhetlo a 1.1 ho phalla ho tloaelehileng e le phallo e phahameng.

2. Sesebelisoa sa sesebelisoa se hlokahalang ho phahamisa pompo ke data e 'ngoe ea bohlokoa ea ts'ebetso, tšebeliso e akaretsang ea amplification 5% -10% margin ho ea hloohong ka mor'a khetho.

3. Thepa ea mokelikeli, ho kenyeletsoa lebitso la bohareng ba mokelikeli, thepa ea 'mele, thepa ea lik'hemik'hale le lisebelisoa tse ling, tse amanang le hlooho ea tsamaiso, lipalo tse sebetsang tsa NPS le mofuta o nepahetseng oa pompo, khetho ea thepa ea pompo le ho sebelisa mofuta oo oa mofuta oa tiiso ea shaft.

4. Boemo ba tlhophiso ea liphaephe tsa tsamaiso ea ho kenya li bolela bolelele ba ho fepa metsi, sebaka sa ho romela mokelikeli, bonyane ba boemo ba mokelikeli oa lehlakoreng la ho hula, boemo bo phahameng ba mokelikeli oa lehlakore la ho tsoa, ​​joalo-joalo, le litlhaloso. , bolelele, lisebelisoa, joalo-joalo, e le hore u tsoele pele ho bala hlooho ea comb le ho hlahloba NPSH.

5. Boikemisetso ba maemo a tshebetso, tse kang mokelikeli tshebetso T tlala mouoane khatello, suction lehlakoreng khatello ea (ka ho feletseng), ho qhala lehlakoreng sejana khatello ea, bophahamo ba, ambient mocheso opereishene ke lekhalo kapa e tsoelang pele, hore na boemo pompo e tsitsitseng kapa fallisehang ea. Ke motheo oa bohlokoa oa khetho. Lisebelisoa tse kang pompo ea tšepe e sa jeleng ea AFB e sa jeng, CQF boenjiniere ba polasetiki ea pompo ea motlakase ea motlakase.

Bakeng sa phetisetso ea likaroloana tse tiileng tse nang le mecha ea phatlalatso, tšebeliso ea likaroloana tsa convective e ne e hloka lisebelisoa tse sa sebetseng, haeba ho hlokahala, ho tiisa shaft ka rinse e hloekileng ea metsi.

Tlhophiso ea liphaephe tsa lipompo tsa lik'hemik'hale

Ka moralo oa moralo oa lipeipi, o lokela ho ela hloko tse latelang:

A. Khetho e utloahalang ea bophara ba pipe, bophara ba pipe, ka tekanyo e lekanang ea phallo, lebelo la phallo le lenyenyane, tahlehelo ea ho hanyetsa e nyenyane, empa theko e phahame, bophara ba pipe e nyenyane, e tla lebisa keketseho e matla ea tahlehelo ea ho hanyetsa. , hlooho ea pompo e eketseha Ka ho eketseha ha matla, litšenyehelo le litšenyehelo tsa ts'ebetso li eketsehile. Kahoo ho lokela ho nahanoa ka pono ea tekheniki le moruo.

B. Pipe ea ho ntša metsi le lisebelisoa tsa eona li lokela ho khona ho hopola khatello e phahameng ka ho fetisisa.

C. tlhophiso ea peipi e lokela ho hlophisoa ka mokhoa o otlolohileng ka hohle kamoo ho ka khonehang ho fokotsa li-fittings tsa phala le ho fokotsa bolelele ba phala e tlameha ho fetoloa ha radius e kobehang ea bophara ba phala ea setsoe e lokela ho ba makhetlo a 3 ho isa ho a 5 a angle ka hohle kamoo ho ka khonehang ho feta. 90 Lt; 0 & gt; C.

D. Lehlakore la ho tsoa ha pompo le tlameha ho ba le li-valve (bolo kapa globe valve, joalo-joalo) le valve ea ho hlahloba. Valve e sebelisetsoa ho lokisa ntlha ea ts'ebetso ea pompo. Sesepa sa ho hlahloba se thibela pompo ho khutlela morao ha mokelikeli o khutlela morao 'me o thibela pompo ho otla hamore ea metsi. (Ha mokelikeli o khutla, o tla ba le khatello e kholo ea morao, tšenyo ea pompo).
