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 yehliselwa ezingeni lokushisa eligcwele umhwamuko woketshezi, uketshezi luzohwamuka kwenze amabhamuza aqale kancane kancane; 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). Ukulinganiswa kwe-cavitation kwenzeka lapho imvamisa yesando samanzi ewuketshezi 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 we-liquid ogelezayo 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 ipompo inyakaze 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 , azokhipha ukucekelwa phansi kwamakhemikhali okuthile ( ukucekelwa phansi kokuqala kuyinhloko).
