CENTRIFUGAL SLURRY PUMP WHEEL |
摘要 |
FIELD: mechanical engineering; pumps. SUBSTANCE: wheel installed for rotation in spiral housing of centrifugal slurry pump has inlet hole made coaxially with axis of wheel rotation, outlet hole located on its periphery and number of blades passing radially between inlet and outlet holes. Neighboring blades form channels to let slurry flow when wheel rotates. Width of each channel measured along line perpendicular to meridional laminar flow of slurry is made gradually narrowing towards wheel periphery. Dimensions of wheel relative to spiral housing are chosen from the following expressions: <EMI ID=0.535 HE=15 WI=90 TI=CHI> where b<SB>1</SB> is width of channel measured at inlet; b<SB>2</SB> is width of channel at wheel periphery; D<SB>2</SB> is wheel diameter; b<SB>3</SB> is width of spiral housing. Specific speed of wheel is 22-30. EFFECT: increased capacity and wear resistance of pump. 6 cl, 4 dwgh
