Slurry cavitation inji
A musamman siffar da ruwan wukake da m kwarara a cikin abin da kwatsam canji a cikin kwarara halaye na ruwa a cikin slurry kwarara impeller, yin leaf fili ruwa matsa lamba rarraba gabatar rashin daidaituwa.
Ruwan ruwa na mashigar mashigar ruwa , ruwan ba ya aiki a kan ruwan kafin , akwai yanki mara ƙarfi a gida . Lokacin da ƙananan matsa lamba na ruwa kwararan matsa lamba aka rage zuwa cikakken tururi zafin jiki na ruwa , ruwan zai tururi zuwa samar da kumfa a hankali ya fara; kumfa tare da ruwan da ke gudana a cikin hanyar gudana a lokacin kuma mafi girman matsin lamba na wucin gadi. Lokacin da kumfa ya fashe , ruwan da ke kewaye da kumfa ya fashe kumfa a lokacin da saurin kwararar ramuka , kuma yana tare da yanayin zafi mai girma , babban yanayin guduma na ruwa , wanda shine tsarin cavitation . Dangane da binciken gwaji na masana na kasashen waje sun ruwaito guduma ruwa na cavitation sune manyan fasalulluka na matsa lamba har zuwa 30MPa (yankin manometry na 1.5mm2). An auna cavitation yana faruwa a lokacin da mitar guduma ruwa na 25,000 sau / second , da karfe saman karkashin ruwa guduma domin akai-akai buga da gajiya lalacewa.
Kuma , a ci gaba da hawan igiyar ruwa , ruwa yana shiga da sauri cikin ramukan karfe , saman karfen wani magudanar ruwa , barbashi na karfe da ruwan da ke nesa da uwa , wanda ke haifar da rami mai tsanani . Manyan sassa na famfo a cikin irin wannan karfi na lokaci-lokaci , famfo zai haifar da hayaniya da rawar jiki , don haka famfo cavitation babban lahani , yafi a cikin wadannan al'amurran : Performance na famfo nosedive.
A wannan gaba HQ lankwasa, NQ mai lankwasa yanayin ƙasa kwatsam,slurry famfo manufacturermai tsanani famfo ba ya aiki, da famfo kwarara katsewa , yafi saboda famfo cavitation , da impeller da makamashi canja wuri tsakanin gudana ruwa lalacewa da tsangwama , da ruwa tashar katange ba kawai da kumfa , da kwarara hasara yana ƙaruwa. Hoto 2: Slurry famfo yana haifar da rawar jiki da amo. Cavitation yana faruwa lokacin da matsa lamba yana da girma tare da kumfa suna rushewa a ci gaba da samar da girgiza mai ƙarfi mai ƙarfi, yin girgizar famfo da amo.
Slurry famfo inji surface kwarara aka gyara daga inji lalacewa , da surface na impeller saƙar zuma ko spongy. Idan iskar gas da aka fitar a lokacin turɓayar ruwa ya lalace , zai haifar da wani lalatar sinadari (lalacewar tsohon shine babban).
