Izinhlayiya zensimbi noketshezi kude nomama

I-Slurry cavitation mechanism

Umumo othize wama-blades nokugeleza okusheshayo lapho ukuguqulwa okungazelelwe ezicini zokugeleza koketshezi ku-Slurry flow impeller, okwenza ukusabalalisa komfutho wepheshana leqabunga kwethulwe ukungalingani.

I-liquid phase inlet flow blade , i-blade ayisebenzi kuketshezi ngaphambili , kunesifunda sokucindezela okuphansi endaweni.Lapho indawo enengcindezi ephansi yokucindezela kokugeleza koketshezi yehliswa ibe yizinga lokushisa eligcwele umhwamuko woketshezi, uketshezi luzohwamuka lube amabhamuza kancane kancane luqale;amabhamuza anoketshezi olugeleza endleleni yokugeleza ngaleso sikhathi futhi kulapho ingcindezi ikhuphuka khona edlula isikhathi eside .Ngesikhathi lapho ibhamuza liqhuma khona, uketshezi oluzungeze ibhamuza lwaqhuma amabhamuza lapho izimbobo zingena ngokushesha, futhi luhambisana nezinga lokushisa eliphezulu lendawo, isenzakalo sesando samanzi somfutho ophezulu, okuwumshini we-cavitation.Ngokusho kwezazi zakwamanye amazwe ucwaningo lokuhlola olubike ukuthi isando samanzi se-cavitation yizici eziyinhloko zengcindezi eyingxenye efika ku-30MPa (indawo ye-manometry engu-1.5mm2).Kukalwe i-cavitation yenzeka lapho isando samanzi samanzi imvamisa izikhathi ezingama-25,000 / isekhondi, indawo yensimbi ngaphansi kwesando samanzi ishaywa ngokuphindaphindiwe ngomonakalo wokukhathala.

Futhi, kugagasi lomfutho we-cyclical oqhubekayo , uketshezi lungena luphume ngokushesha ezimbotsheni zensimbi , ingaphezulu lensimbi le-concavity , izinhlayiya zensimbi noketshezi kude nomama, okuholela emigodini enzima.Izingxenye ezinkulu zephampu kumandla anjalo ezikhathi ezithile, iphampu izobangela umsindo nokudlidliza, ukuze i-cavitation yepompo ibe yingozi enkulu, ikakhulukazi kulezi zici ezilandelayo: Ukusebenza kwe-nosedive yepompo.

Kuleli qophelo ijika le - HQ , i- NQ ijikela phansi ngokuzumayo ,umkhiqizi wepompo ye-slurryiphampu enzima ayisebenzi, ukuphazamiseka kokugeleza kwepompo , ikakhulukazi ngenxa yepompo ye-cavitation, i-impeller kanye nokudluliswa kwamandla phakathi komonakalo ogelezayo we-liquid nokuphazamiseka, umzila we-fluid uvinjelwe hhayi kuphela nge-bubble, futhi ukulahlekelwa kokugeleza kuyanda.Umfanekiso 2 : Iphampu ye-slurry ikhiqiza ukudlidliza nomsindo.I-Cavitation yenzeka lapho ingcindezi iphezulu kanye namabhamuza ewa ngokuqhubekayo akhiqiza ukushaqeka okuqinile kwe-hydraulic, okwenza ukudlidliza kwepompo nomsindo.

Ipompo ye-slurry mechanical surface flow components kusukela ekulimaleni komshini , ingaphezulu lekhekheba lezinyosi le-impeller noma isiponji.Uma amagesi akhishwa ngesikhathi sokuhwamuka koketshezi egqwala , azokhiqiza ukucekelwa phansi kwamakhemikhali okuthile ( ukucekelwa phansi kwalowokuqala yikho okuyinhloko .
