| titleOfInvention | A kind of pump semi-spiral suction chamber Hydraulic Design Method |
| abstract | The invention provides a kind of pump semi-spiral suction chamber Hydraulic Design Method.Utilize following relation to determine the main geometric parameters of suction chamber, mainly comprise: cut water angle α, cut water angle γ, radius R on the upside of suction chambern 1 , cut water gateway radius rn 1 , Base radius Rn 2 , radius R on the downside of suction chambern 3 , the long l of dividing plate, dividing plate angle theta, block board thickness δ, eight section inlet radius bn 3 , eight section tilt angle ω, each cross sectional radii Rn i , the long l of each section leveln i with each section height hn i .Not only improve flox condition with the suction chamber of the present invention's design, can ensure to obtain uniform velocity field at impeller inlet, substantially increase the anti-cavitation performance of pump simultaneously. |
