Slurry cavitation mechanism
Mamiriro chaiwo emashizha uye kukurumidza kuyerera umo kushanduka kamwe kamwe kwemaitiro ekuyerera kwemvura muSlurry flow impeller, zvichiita kuti mashizha emashizha emvura awedzere kugovera kugovera kusaenzana.
Iyo liquid phase inlet flow blade , blade haisi kuita pamvura kare , kune nzvimbo yakaderera yekumanikidza munharaunda. Kana yakadzikira kudzvinyirirwa nzvimbo yekuyerera kwemvura inoderedzwa kusvika kune yakazara mhute tembiricha yemvura, iyo mvura inoputika kuita mabubble zvishoma nezvishoma akatanga; mabhavhu ane mvura inoyerera munzira yekuyerera panguva iyoyo uye iyo inokwira inodonha isingaperi . Panguva iyo bubble rakaputika, mvura yakatenderedza bubble yakaputika mabubbles akaumbwa apo kukurumidza kuputika kwemakomba, uye inoperekedzwa ne localized high temperature, high pressure water sando phenomenon, inova iyo mechanic of cavitation. Zvinoenderana nenyanzvi dzekune dzimwe nyika ongororo yekuongorora yakashuma cavitation mvura sando ndiwo akanyanya maficha ekumanikidza kunosvika 30MPa (manometry nzvimbo ye1.5mm2). Yakayerwa cavitation inoitika kana mvura yemvura sando frequency ye25,000 times / sekondi, iyo simbi pamusoro pemvura sando yekudzokorora kurohwa nekuneta kukuvara.
Uye, muinoenderera mberi cyclical pressure wave , mvura inokurumidza kupinda nekubuda mumapores esimbi , simbi yepamusoro pe concavity , zvimedu zvesimbi uye mvura iri kure naamai , zvichikonzera kupinza kwakanyanya . Zvikamu zvakakura zvepombi mune yakadaro periodic simba , pombi ichaita ruzha uye kuzununguka, kuitira kuti pombi cavitation ikuvadze zvikuru, kunyanya mune zvinotevera: Kuita kwepombi nosedive.
Panguva ino HQ curve, NQ curve yakadzika maitiro nekukurumidza,slurry pombi mugadziripombi yakaoma haishande, kukanganiswa kwepombi kuyerera, kunyanya nekuda kwepombi cavitation, iyo impeller uye simba rekufambisa pakati pemvura inoyerera kukuvara uye kupindira, chiteshi chemvura chakavharwa kwete chete nebubble, uye kurasikirwa kwekuyerera kunowedzera. Mufananidzo 2: Slurry pombi inoburitsa kuzunguzika uye ruzha. Cavitation inoitika kana dzvinyiriro yakakwira pamwe chete nemabhuru anodonha painoenderera ichigadzira yakasimba hydraulic shock, zvichiita kuti pombi idengenyeke uye ruzha.
Slurry pombi mechanical pamusoro kuyerera zvikamu kubva mechanical kukuvara, pamusoro peimpeller huchi kana spongy. Kana magasi anoburitswa panguva yekupisa kwemvura achiora, anoburitsa kumwe kuparadza kwemakemikari (kuparadzwa kweiyo yekutanga ndiyo huru).
