Kwinkqubo ye-hydraulic, i-cavitation yinto apho utshintsho olukhawulezayo loxinzelelo kwioli lubangela ukubunjwa kwemigodi emincinci ezaliswe ngumphunga kwiindawo apho uxinzelelo luphantsi. Nje ukuba uxinzelelo lwehliselwe ngaphantsi komgangatho womphunga ogcweleyo kwiqondo lobushushu bokusebenza kwe-oyile, inani lemingxuma ezaliswe ngumphunga iya kwenziwa ngokukhawuleza. Ngenxa yoko, inani elikhulu lamaqamza omoya likhokelela ekuyekisweni kweoyile kumbhobho okanye izinto ezisebenza ngehydraulic.
I-phenomenon ye-cavitation ngokuqhelekileyo iyenzeka ekungeneni nasekuphumeni kwe-valve kunye nepompo. Xa i-oyile ihamba ngendlela emxinwa yevalve, isantya sesantya solwelo siyenyuka kwaye uxinzelelo lweoyile luyehla, ngaloo ndlela kukho i-cavitation. Ukongezelela, le nto ibonakala xa ipompo ifakwe kwindawo yokuphakama, ukuchasana kwe-oyile kukhulu kakhulu ngenxa yokuba ububanzi bangaphakathi bombhobho wokufunxa buncinci kakhulu, okanye xa ukufunxa kwe-oyile kunganelanga ngenxa yesantya sepompo siphezulu kakhulu.
Amaqamza omoya, ahamba kwindawo yoxinzelelo oluphezulu ngeoyile, aphuka ngokukhawuleza ngenxa yomzamo woxinzelelo oluphezulu, aze ke amasuntswana angamalwelo ajikelezileyo ahlawule amaqamza ngesantya esiphezulu, kwaye ngaloo ndlela ungquzulwano lwesantya esiphezulu phakathi kwala masuntswana luvelisa impembelelo yehydraulic. Ngenxa yoko, uxinzelelo kunye nobushushu ngokuyinxenye buyanda kakhulu, bubangela ukungcangcazela okubonakalayo kunye nengxolo.
Kudonga olungqindilili olujikelezileyo apho imingxuma ijiyile kunye nomphezulu wezinto, amasuntswana esinyithi angaphandle ayawa, ngenxa yokubandezeleka kwexesha elide ngenxa yempembelelo yehydraulic kunye nobushushu obuphezulu, kunye neenzame eziyingozi ezibangelwa yirhasi evela kwioyile.
Emva kokubonisa i-phenomenon ye-cavitation kunye nesiphumo sayo esibi, siyavuya ukwabelana ngolwazi lwethu kunye namava okuba singayinqanda njani ukuba ingenzeki.
【1】 Nciphisa ukuhla koxinzelelo kwindawo yokuhamba ngemingxuma encinci kunye ne-interspaces: umlinganiselo olindelekileyo woxinzelelo lokuhamba ngaphambi nangemva kwemingxuma kunye ne-interspaces i-p1 / p2 <3.50.
【2】Chaza ubukhulu bombhobho wokufunxa wempompo yoxinzelelo ngokufanelekileyo, kwaye unciphise isantya solwelo kumbhobho ngeendlela ezininzi; nciphisa ukuphakama kokufunxa kwempompo, kwaye unciphise umonakalo woxinzelelo kumgca wokungena kangangoko kunokwenzeka.
【3】 Khetha i-T-junction yomgangatho ophezulu wokungangeni moya kwaye usebenzise impompo yamanzi yoxinzelelo oluphezulu njengempompo encedisayo ukubonelela ngeoyile.
【4】Zama ukwamkela yonke imibhobho ethe tye kwisixokelelwano, unqanda ukujika okubukhali kunye nokuqhekeka okuncinci kancinci.
【5】Phucula isakhono sokumelana nerhasi.
