Slurry pump inviscid flow solution
Slurry inviscid flow technology inosanganisira zvinotevera: (a) two-dimensional cascade flow theory;(2) maviri-dimensional uye matatu-dimensional anogona kuyerera mhinduro;(3) maviri-dimensional quasi-matatu-dimensional, rwizi basa equations;(4) maviri dimensional uye matatu-dimensional Euler equations;(5) dzidziso yechipiri.
Slurry-dimensional cascade theory inzira iri nyore, iyo inonyanya kushanda mukumanikidza uye kufanotaura kwehupfumi.Uyezve fungidzira nzvimbo yekuyerera zvishoma zvishoma.Naizvozvo, sezvo Muzvinafundo Wu Zhonghua vakakurudzira kupa zviso zviviri zvakapesana zvedzidziso huru yekuyerera, maverengero ekuyerera anokwana matatu-matatu akaita mhedzisiro inokwezva maziso.Parizvino, indasitiri yeindasitiri yakashandiswa zvakanyanya.Katsanits naMeokally, Krimmerman naAdler vakagadzira tekinoroji iyi.Domestic Xin Xiao Kang Jiang Jinliang akaita chero Dingzhun orthogonal pamusoro nzira, Wu Yulin, etc. vachishandisa nzira iyi kuverenga yakasanganiswa slurry pombi hydraulic muchina.
Mumakore ekuma1980, isina-namira komputa mainstream yakashandura Euler equations, iyo inokonzerwa ne-dimensional-dimensional inogona kuyerera uye dzimwe nzira hadzigone kufunga nezve whirlpool mhedzisiro inogona kupihwa kune ese viscous kurasikirwa kwakatambura kurasikirwa ukoshi.
Mumakore achangopfuura, matatu-dimensional asina-sticky gravelslurry pombiKukura kwemakomputa, vanhu vazhinji vari kutendeukira kubasa kunyanya zvinosanganisira muganhu weviscous flow calculation nzira, Navier-Stokes equations chikamu chemakemikari nzira uye Navier-Stokes equations.
Nzira dzinowanzo shandiswa dzekugadzirisa muganho inzira yakakosha uye inogumira misiyano nzira mapoinzi.Kubva pakuvandudzwa kwekombiyuta yekombiyuta, iyo yakazotevera zvishoma nezvishoma yakatsiva yekare.Arakawa et axial pombi ine yakakosha nzira yekugadzirisa iyo-matatu-dimensional mhirizhonga muganho layer pablade;Lakshminarayana yekubatanidza nzira yakadai sekushandisa turbine blade uye impeller opium dimensional edge kirasi kufamba, iyo coefficient yekukwesha pakati pepamusoro kuburikidza nekuunzwa kweiyo yakagadziridzwa nzira inotarisisa mukutenderera, curvature uye kumanikidza gradient maitiro parizvino.Vasta kunze kwenyika kweiyo isiri-orthogonal kutenderera inoronga inoenderana muganhu weiyo equations uye mhinduro nzira;Anderson akaita zvimwe zvigadziriso, achishandisa chiyero chakayerwa uye nepamusoro peEuler equations,Matanho ekushanda epombi ine slurrydhirowa muganho layer wekunze kwemuganhu mamiriro, uye wobva waverenga kutenderera cascade kuyerera kwenzvimbo yekumanikidza.Mhedzisiro yeinogumira misiyano nzira inosanganiswa nekuyedza, Wu Yulin, kuverenga michina yekuchengetedza mvura pamamiriro ekunze-dhizaini, fungidzira kupatsanurwa kwenzvimbo kweiyo impeller inotungamira uye inoteedzera kumucheto.
Gravel pombi solid-liquid musanganiswa inoyerera ichipinda mupfupi chubhu ichibva kune inosveta impeller, iyo yakasimba zvimedu kupinda muradial uye axial kufamba kuenda kune yekumashure chivharo, nekuda kwekuita inertia pachivharo chekumashure chakabonderana nevhavha yekumashure kuti imirisane nemhedzisiro yezvimedu zvakakura. simba, kuwedzera kupfeka uye kubvarura.Zvizhinji zvezvimedu zvakasimba padhuze neblade kubva kune blade inotungamira kumeso kweblade kupinda mugero rekuyerera, uye chikamu cheblade padyo nekuseri kwezvimedu munzira yekuyerera.Morphology kubva kune impeller kupfeka uye abrasion mhedzisiro, kubva kumberi kumucheto wemupendero weblade inopfeka ekuwedzera.Kupomba musanganiswa wezvimedu zvakapfava, nzira yekuyerera yeblade uye blade-mhando inofamba nzira ye curvature yakafanana neblade kumeso kwekupfeka kwakatambura zvakanyanya kupfuura mablades kumashure.
Gravel pombi yakasimba zvidimbu zvinobuda kubva pablade, apo muzvikamu zvakatsetseka madiki ekona ekubuda achitevedza nzira yekufamba.Yakatarisana nekunze kwekunze kweiyo impeller musanganiswa inoyerera nzvimbo,API standard zvinorevazvidimbu zvakanaka zvine diki radial velocity.Musanganiswa unoburitswa zvishoma nezvishoma kubva kune impeller uye yemukati madziro emadziro ekuyerera kwepombi, zvimedu zvakasimba zvakawedzera zvishoma nezvishoma, iyo impeller blade yekubuditsa mupendero inomira kutonhora musanganiswa basa reblade rekubuda mupendero weblade rinopfeka zvakaipisisa zvikamu.
