Pfeka dhizaini zvinhu slurry pombi mugadziri's Vazhinji vanopfeka dhizaini zvinhu slurry pombi mugadziri, uye zvikamu zvakasiyana uye zvikamu zvakasiyana zvemashini ekupfeka hazvina kufanana, asi kazhinji zvinogona kupfupikiswa mumapoka matatu:
1 Kukukurwa: Mumugadziri wepombi inotsvedza panguva yekushanda, iyo mvura kune yakasimba zvimedu inotakurwa muyero yekuyerera pamusoro peiyo inokanganisa nhengo, zvichikonzera kurasikirwa kwezvinhu.Zvinoenderana nekuongorora kwekutadza kwechikamu chekupfeka erosion meshini inogona kukamurwa kuita yekucheka kupfeka uye deformation kupfeka uye kupera simba kwekucheka + composite deformation.
2 cavitation kukuvadzwa: Panguva yekushanda kwepombi, iyo inoyerera zvikamu izvo dunhu renzvimbo (kazhinji pane impeller inlet gare gare), nekuda kwechimwe chikonzero, iyo mvura yakapombera mukati menguva iyo mhedziso yekudzvinyirirwa inodonha kune iyo mhute yekumanikidza kwekushisa, uko. mvura inotanga kunyungudutswa kuti ibudise chiutsi , kuumbwa kwemabhuru.Aya mabhuru ane mvura inoyerera kumberi, kusvika kune yakakwira dzvinyiriro, mabhuru anodonha zvakanyanya akaderedzwa.Zvichakadaro mububble condensation, zvimedu zvemvura pahupamhi hwekuzadza voids, uye zvine simba rakasimba pane simbi pamusoro.Iyi metal surface spalling nekuda kwekuneta , zvichikonzera kurasikirwa kwezvinhu , simbi yakaomarara inoratidza huchi .Zvikamu zvecavitation zvinowanzoitika mune impeller outlet uye volute inlet.
3 corrosive kupfeka: Kana iyo yekufambisa svikiro ine imwe pH,slurry pombi mugadzirikuyerera zvinhu zvichaitika corrosion wear, kureva kurasikirwa kwezvinhu zvinoitika pasi pekubatana kwekuita ngura uye kupfeka.
Corrosion inogona kukamurwa kuita makemikari ngura uye electrochemical corrosion.Kemikari corrosion yesimbi uye yemvura midhiya mhinduro yakananga inosiya kurasikirwa kwesimbi, electrochemical corrosion mune yemvura yepakati ibasa resimbi yepasi kugadzira micro-bhatiri ichisiya kurasikirwa kwezvinhu.Sezvo chaiyo kushandiswa kwesimbi zvinhu zviri multiphase polycrystalline zvinhu, saka, a primary corrosion , electrochemical corrosion , kunyanya crystal boundary corrosion, intergranular cracks inoumbwa simbi pamusoro, uye kuparadzanisa yakaoma chikamu tsanga kana, yakarasika rutsigiro, saka ichabuda. mukukukurwa kwakaitika zvimedu zvakasimba;paanenge achikwesha zvidimbu zvakasimba , uye simbi yepasi inokonzera ngura nekuda kwe passivation layer inokwizwa kuti ibudise mvura yepakati inosangana nesimbi kuti iwedzere kutsva.Slurry pombi mugadziri mukutadza kuongororwa kwekuvapo kwechiitiko kwakawanikwa kuve nekuora.
