Mbelata olu na iji gbochie mfu nke mgbapụta slurry
Mpịakọta nke centrifugal china slurry mgbapụta mgbapụta mgbanaka mgbanaka mfu, mfu nke nguzozi n'etiti ụlọ ọrụ na ọkwa nke mfu ntapu.
Mfu mgbanaka akara akara
Na ntinye nke impeller , mgbanaka akara na china slurry mgbapụta ọrụ, n'ihi na akara mgbanaka na n'akụkụ abụọ e nwere a nrụgide dị iche , n'akụkụ nke impeller mmepụta ihe bụ ihe dị ka otu akụkụ nke impeller mbata mgbali , ya mere a ga-enwe mgbe niile. akụkụ nke mmiri mmiri si n'oghere impeller gaa na ntapu mmiri nke impeller.Nke a akụkụ nke mmiri mmiri nwetara na ike nke impeller , ma mmiri mmiri adịghị eziga, si otú ibelata ego nke mmiri china slurry mgbapụta .Ike niile eji emeri mgbanaka mgbanaka akara mmiri na nguzogide.
N'ụzọ doro anya, ka nnukwu akara mgbanaka akara Dw, ka ọ na-adabawanye n'akụkụ abụọ nke ọdịiche nrụgide, na-abawanye ụba nke ntapu.N'ihi na stereotypes china slurry nfuli, iji belata ọnụ ọgụgụ nke ntapu iji melite arụmọrụ nke china slurry mgbapụta kwesịrị ikwe na ihe nke akara mgbanaka ọdịiche dị warara.A na-atụkarị mkpokọta mkpochapụ mgbanaka mgbanaka mgbanaka 0.002, dịka Dw = 200 mm, mkpokọta mkpochapụ nke 0.40 mm.Mgbe a na-agbakọta, mgbanaka akara eccentrically adịghị oke ibu, ma ọ bụghị ya, ọnụ ọgụgụ nke ntapu ga-abawanye.Ihe ọzọ dị mkpa eji eme ihe iji mee ka nkwụsị nke usoro mgbanaka akara maka ibelata ọnụọgụ nke ntanye, mee ka nkwụsị nke mgbanaka akara na-eme ka maze, zigzag, wdg.
