Ka har'a tsamaiso ea hydraulic, cavitation ke ketsahalo eo ho eona liphetoho tse potlakileng tsa khatello ka oli li bakang ho thehoa ha likoti tse nyenyane tse tletseng mouoane libakeng tseo khatello e batlang e le tlaase. Hang ha khatello e fokotseha ho ba ka tlase ho boemo ba mouoane o tletseng mocheso mochesong o sebetsang oa oli, ho tla hlahisoa likoti tse ngata tse tlatsitsoeng ke mouoane hang-hang. Ka lebaka leo, palo e kholo ea li-bubble tsa moea e lebisa ho khaotsoa ha oli ka phala kapa likarolo tsa haeteroliki.
Ketsahalo ea cavitation hangata e etsahala monyako le ho tsoa ha valve le pompo. Ha oli e phalla ka tsela e patisaneng ea valve, lebelo la mokelikeli le eketseha 'me khatello ea oli e fokotseha, kahoo cavitation e etsahala. Ho phaella moo, ketsahalo ena e hlaha ha pompo e kenngoa sebakeng se phahameng ka ho fetisisa, khanyetso ea ho monya oli e kholo haholo hobane bophara bo ka hare ba phala ea ho hula bo nyenyane haholo, kapa ha ho kenngoa ha oli ho sa lekana ka lebaka la lebelo la pompo le phahameng haholo.
Li-bubble tsa moea, tse tsamaeang sebakeng sa khatello e phahameng ka oli, li robeha hang-hang ka lebaka la boiteko ba khatello e phahameng, ebe likaroloana tsa mokelikeli tse potolohileng li lefella li-bubble ka lebelo le phahameng, kahoo ho thulana ka lebelo le phahameng pakeng tsa likaroloana tsena ho hlahisa karolo e itseng ea hydraulic. Ka lebaka leo, khatello le mocheso ka karolo e 'ngoe li eketseha haholo, li baka ho thothomela le lerata.
Lerakong le letenya le pota-potileng moo likoti li hokamang le bokaholimo ba lintho, likaroloana tsa tšepe tse kaholimo lia oa, ka lebaka la ts'oaetso ea nako e telele ea hydraulic le mocheso o phahameng, hammoho le matla a senyang a bakoang ke khase e tsoang oli.
Ka mor'a ho hlalosa ketsahalo ea cavitation le liphello tsa eona tse mpe, re thabela ho arolelana tsebo ea rona le phihlelo ea hore na re ka e thibela joang hore e se ke ea etsahala.
【1】 Fokotsa ho theoha ha khatello sebakeng sa ho phalla ka likoti tse nyenyane le li-interspaces: tekanyo e lebeletsoeng ea khatello ea ho phalla pele le ka morao likoti le li-interspaces ke p1/p2 <3.50 .
【2】 Hlalosa bophara ba pompo ea haeteroliki e monyang pompo ka nepo, le ho thibela lebelo la mokelikeli ka har'a phaephe ka litsela tse ngata; fokotsa bophahamo ba ho huloa ha pompo, le ho fokotsa tšenyo ea khatello moleng o kenang ka hohle kamoo ho ka khonehang.
【3】 Khetha T-junction ea boemo bo holimo e thibelang moea 'me u sebelise pompo ea metsi e nang le khatello e phahameng e le pompo e thusang ho fana ka oli.
【4】 Leka ho sebelisa liphaephe tsohle tse otlolohileng ka har'a sistimi, ho qoba ho thinya ho nchocho le lekhalo le moqotetsane.
