Indlela yokucima i-slurry cavitation
Imilo ethile yeencakuba kunye nokuhamba okukhawulezileyo apho utshintsho lwesiquphe kwiimpawu zokuqukuqela kolwelo kwi-slurry flow impeller , ukwenza igqabi legqabi lonikezelo loxinzelelo lolwelo libonise ukungalingani.
I-blade yesigaba solwelo sokungena , iblade ayisebenzi kulwelo ngaphambili , kukho ummandla woxinzelelo oluphantsi ekuhlaleni .Xa ummandla woxinzelelo oluphantsi loxinzelelo lokuhamba kolwelo luncitshiswa ukuya kubushushu bomphunga ogcweleyo wolwelo , ulwelo luya kunyuka lube ngumphunga lube amaqamza ngokuthe ngcembe aqale ;amaqamza anolwelo oluqukuqelayo kwindlela yokuqukuqela ngelo xesha kwaye kokukhona uxinzelelo oludlulayo luhla .Umzuzwana uqhuma i-bubble, i-fluid ejikeleze i-bubble yaqhuma i-bubbles eyenziwa xa i-influx esheshayo yemingxuma, kwaye ihamba kunye nobushushu obuphezulu bendawo, i-high pressure water hammer phenomenon, eyona ndlela ye-cavitation.Ngokutsho kwabaphengululi bamazwe angaphandle uphononongo lovavanyo oluchazwe kwisando samanzi se-cavitation zizinto eziphambili zoxinzelelo oluyinxenye ukuya kwi-30MPa (indawo ye-manometry ye-1.5mm2).Ukulinganisa i-cavitation kwenzeka xa i-liquid water hammer frequency ye-25,000 amaxesha / okwesibini, indawo yesinyithi phantsi kwesando samanzi ngokuphindaphindiweyo ibethelwa ngumonakalo wokukhathala.
Kwaye, kwi-cyclical wave yoxinzelelo oluqhubekayo, ulwelo lukhawuleza lungene kwaye luphume kwi-pores yesinyithi, umphezulu wesinyithi we-concavity, amasuntswana esinyithi kunye nolwelo olukude kumama, okubangela ukugoba okukhulu.Iinxalenye ezinkulu zempompo kumandla exesha elinjalo , ipompo iya kubangela ingxolo kunye nokugubha, ukwenzela ukuba ipompo cavitation ingozi enkulu , ngokukodwa kule miba ilandelayo : Ukusebenza kwe-nosedive yepompo.
Kweli nqanaba ijika le-HQ , i-NQ ijika ijika ngesiquphe ,umenzi wempompo enodakaimpompo enzima ayisebenzi, ukuphazamiseka kokuhamba kwempompo, ngokukodwa ngenxa yempompo ye-cavitation, i-impeller kunye nokudluliselwa kwamandla phakathi komonakalo ohambayo wamanzi kunye nokuphazamiseka, umjelo we-fluid uvaliwe kungekhona nje nge-bubble, kwaye ukulahleka kokuhamba kuyanda.Umzobo 2: Impompo ye-slurry ivelisa ukungcangcazela kunye nengxolo.I-Cavitation iyenzeka xa uxinzelelo luphezulu kunye nokuwa kwe-bubbles ngokuqhubekayo kuvelisa i-shock hydraulic shock, okwenza i-vibration yepompo kunye nengxolo.
Impompo ye-slurry mechanical surface flow components ukusuka kumonakalo womatshini, umphezulu we-honeycomb ye-impeller okanye i-spongy.Ukuba iirhasi ezikhutshwe ngexesha lokwenziwa ngumphunga kolwelo ziyonakalisa , ziya kuvelisa ukutshatyalaliswa kweekhemikhali ezithile ( ukutshatyalaliswa kweyokuqala iyona nto iphambili .
