Kwinkqubo ye-hydraulic, i-cavitation yinto apho utshintsho olukhawulezileyo loxinzelelo kwi-oyile lubangela ukwakheka kwemingxuma emincinci egcwele umphunga kwiindawo apho uxinzelelo luphantsi khona. Nje ukuba uxinzelelo lwehle lube ngaphantsi komphunga ogcweleyo kubushushu bokusebenza kwe-oyile, inani lemingxuma egcwele umphunga liya kuveliswa ngokukhawuleza. Ngenxa yoko, inani elikhulu lamaqamza omoya likhokelela ekuphelisweni kwe-oyile kwimibhobho okanye kwizinto ze-hydraulic.
Imeko yokugalela ioyile idla ngokwenzeka ekungeneni nasekuphumeni kwevalvu kunye nepompo. Xa ioyile idlula kwindlela encinci yevalvu, isantya solwelo siyanda kwaye uxinzelelo lweoyile luyehla, ngaloo ndlela kuyenzeka ukugalela ioyile. Ukongeza, le meko ivela xa ipompo ifakelwe kwindawo ephakame kakhulu, ukumelana nokugalela ioyile kukhulu kakhulu kuba ububanzi bangaphakathi bombhobho wokufunxa buncinci kakhulu, okanye xa ukugalela ioyile kungonelanga ngenxa yesantya sepompo siphezulu kakhulu.
Amaqamza omoya, ahamba kwindawo enoxinzelelo oluphezulu ngeoyile, aqhekeka ngokukhawuleza ngenxa yomgudu woxinzelelo oluphezulu, aze emva koko amaqhekeza olwelo ajikelezileyo ahlawule amaqamza ngesantya esiphezulu, kwaye ngaloo ndlela ukungqubana kwesantya esiphezulu phakathi kwala maqhekeza kuvelisa impembelelo encinci ye-hydraulic. Ngenxa yoko, uxinzelelo kunye nobushushu buyanda kakhulu, nto leyo ebangela ukushukuma okubonakalayo kunye nengxolo.
Kudonga olungqindilili olujikelezileyo apho imingxuma iqina khona kunye nomphezulu wezinto, amasuntswana esinyithi angaphezulu ayawa, ngenxa yokubandezeleka kwexesha elide ngenxa yempembelelo ye-hydraulic kunye nobushushu obuphezulu, kunye nomgudu omkhulu wokubola obangelwa yigesi evela kwioyile.
Emva kokubonisa imeko ye-cavitation kunye nemiphumo yayo emibi, siyavuya ukwabelana ngolwazi lwethu namava ethu ngendlela yokuyithintela ukuba ingenzeki.
【1】Nciphisa ukuhla koxinzelelo kwindawo edlula kuyo imingxunya emincinci kunye neendawo ezidibeneyo: umlinganiselo woxinzelelo olindelekileyo wokugeleza kwemingxunya kunye neendawo ezidibeneyo ngaphambi nasemva kwayo yi-p1/p2 < 3.50.
【2】Chaza ububanzi bombhobho wokufunxa ipompo ye-hydraulic ngokufanelekileyo, kwaye unciphise isantya solwelo ngaphakathi kombhobho ngeendlela ezininzi; yehlisa ubude bokufunxa kwepompo, kwaye unciphise umonakalo woxinzelelo kumgca wokungena kangangoko kunokwenzeka.
【3】Khetha i-T-junction ekumgangatho ophezulu engenamoya kwaye usebenzise ipompo yamanzi enoxinzelelo oluphezulu njengepompo encedisayo yokubonelela ngeoyile.
【4】Zama ukusebenzisa zonke iipayipi ezithe tye kwinkqubo, uphephe ukujika okubukhali kunye nomngxuma omxinwa kancinci.
【5】Phucula amandla ezinto ukuze zikwazi ukumelana nokugrumba kwegesi.
