Qaybaha birta ah iyo dareeraha ka fog hooyada

Habka cavitation slurry

Qaabka gaarka ah ee daabyada iyo socodka degdega ah ee isbeddel degdeg ah oo ku yimaadda sifooyinka dareeraha ee qulqulka qulqulka qulqulka , samaynta qaybinta cadaadiska dareeraha caleenta ayaa soo bandhigtay dheelitir la'aan .

Daabka qulqulka qulqulka wejiga dareeraha , daabku kuma dhaqmaayo dareeraha ka hor , waxaa jira gobolka cadaadis hoose oo gudaha ah . Marka aagga cadaadiska hoose ee cadaadiska socodka dareeraha la yareeyo heerkulka uumiga buuxa ee dareeraha , dareeruhu wuu uumi doonaa si uu u sameeyo xumbo si tartiib tartiib ah u bilaabma ; xumbo leh dareere ku qulqulaya dariiqa qulqulka wakhtiga iyo cadaadiska sare ee burburka ku meel gaadhka ah. Isla markii ay xumbo-ku dillaacdo , dareeraha ku wareegsan xumbo-baxa ayaa dillaacay xumbo markii ay si degdeg ah u soo qulqulayaan godadka , waxaana weheliya heer-kulka sare ee deegaanka , cadaadiska sare ee muuqaalka biyaha , taas oo ah habka daloolista . Sida laga soo xigtay cilmi-baarayaasha ajnabiga ah ee daraasadda tijaabada ah ayaa sheegay in dubbe-biyoodka cavitation ay yihiin astaamaha ugu muhiimsan ee cadaadiska qayb ahaan ilaa 30MPa (aagga manometry ee 1.5mm2). Cavitation-ku wuxuu dhacaa marka dubbe dareere ah inta jeer ee 25,000 jeer / ilbiriqsi, oogada birta ah ee dubbaha biyaha si isdaba joog ah ugu dhuftey dhaawac daal ah.

Iyo , mawjadda cadaadiska meertada ah ee joogtada ah , dareeruhu wuxuu si degdeg ah uga soo baxaa oo ka soo baxaa daloollada birta , birta dusha sare ee daloolka , qaybaha birta iyo dareeraha ka fog hooyada , taas oo keenta godad daran . Qaybaha waaweyn ee bamka ee xoogga xilliyeedka ah , bamku wuxuu keeni doonaa buuq iyo gariir , sidaas darteed matoorka bamka waxyeello weyn , inta badan dhinacyada soo socda : Waxqabadka sanka bamka.

Halkaa marka ay marayso qalooca HQ, NQ hoos u dhaca si lama filaan ah,soo saaraha bamka slurrybamka daran ma shaqeeyo, joojinta socodka bamka , inta badan ay sabab u tahay cavitation bamka , impeller iyo wareejinta tamarta u dhaxaysa burburka dareeraha qulqulaya iyo faragelinta , kanaalka dareeraha xannibay ma aha oo kaliya xumbo , iyo luminta socodka ayaa kordha. Jaantuska 2: Bamka slurry wuxuu abuuraa gariir iyo buuq. Cavitation wuxuu dhacaa marka cadaadiska uu sareeyo oo ay weheliso goobooyinku burburaan at si joogto ah u soo saaro shoog biyo xoog leh , samaynta gariirka bamka iyo buuqa.

Slurry bamka dusha makaanikada qaybaha socodka socodka farsamada ee ka yimaada burburka farsamada, dusha sare ee awllaha malabka impeller ama spongy. Haddii gaasaska la sii daayo inta lagu jiro uumiga dareeraha ay daxaloobaan , waxay soo saari doonaan burbur kiimikaad gaar ah (burburkii hore ayaa ugu weyn ) .
