Engineering pump new favorite slag pump selection and calculation formula

Slurry pump various selection formula formula Slurry pump selection formula is listed in the industry standard, the symbols are unified. 1) Typical slurry method Piping characteristics: Hf = H + (1 + ξ) (V ^ 2) / (2g) slurry Hmo = ΔΗ + 0.72Ko (Vl ^ 2) + 0.58Ko Hs = HR + 0.72Ko (Vl ^ 2) + 0.58Ko (V ^ 2) Clean water Hs = Hs * HR 2) Coal preparation plant method 1 Piping characteristics: Clean water Hf = ΔH + iL + Body Hmo = ΔΗ + imL + 2 Characteristics of the pump: Slurry Hm = ΔΗ + imL + 2 Water Hs = H / Km 3) Ash Removal Method Pipeline characteristics: Clear water Hf = ΔH + 1.05iL Slurry Hmo = ΔΗγm + 1.05imL Characteristics of the pump slurry Hm = 1.1Hmo water Hs = Hs * γm * Km 4) Tailings calculation method Pipeline characteristics: water Hf = ΔH + iL + Σhi slurry Hmo = ΔΗγm + imL + Σhi Pump characteristics: Hm = ΔΗγm + imL + Σhi Clear water Hs = Hs * γm * Km * Kh 5) Fill mining method Pipeline characteristics: Clear water Hf = ΔH + 1.05iL + Σhi slurry Hmo = ΔΗγm + imL + Σhi Pump characteristics: Slurry Hm = ΔΗγm + imL + Σhi Clear water Hs = Hs * Km * Kh 6) Metallurgical mine method Pipeline characteristics: Clear water Hf = ΔH + iL + Σhi slurry Hmo = ΔΗγm + imL + Σhi Pump characteristics: slurry Hm = ΔΗγm + imL + Σhi Clear water Hs = Hs * γm * Kh Symbols and significance of Hf, Hmo, Hm, Hs Hs pipe water Head of the head and the slurry, the head of the slurry and the head of the fresh water; ΔH head loss; L pipe length; i, im friction coefficient of water and slurry; Kh = 1-0.25Cw γm slurry specific gravity; Ko = H / (V ^ 2), water calculation pipeline head and the ratio of the speed of the square. Vl critical sedimentation velocity. Km = Hm / (Vm ^ 2) slurry calculated pipe head and the ratio of the speed of the square.
