Slurry pump various selection calculation formula The slurry pump selection formula is listed in various industry standards, the symbols in the formula are unified. 1) Typical slurry method Pipeline features: Water Hf = ΔH + (1 + ξ) (V ^ 2) / (2g) Slurry Hmo = ΔΗ + 0.72Ko (Vl ^ 2) + 0.58Ko (V ^ 2) Pump features: Slurry Hm = ΔΗ + 0.72Ko (Vl ^ 2) + 0.58Ko (V ^ 2) Fresh water Hs = Hs * HR 2) Coal Preparation Plant 1 Pipeline features: Water Hf = ΔH + iL + 2 Slurry Hmo = ΔΗ + imL + 2 Pump features: Slurry Hm = ΔΗ + imL + 2 Water Hs = H / Km 3) ash calculation method Pipeline features: Fresh water Hf = ΔH + 1.05iL Slurry Hmo = ΔΗγm + 1.05imL Pump characteristics Slurry Hm = 1.1Hmo Water Hs = Hs * γm * Km 4) tailings calculation method Pipeline features: Water Hf = ΔH + iL + Σhi Slurry Hmo = ΔΗγm + imL + Σhi Pump features: Slurry Hm = ΔΗγm + imL + Σhi Water Hs = Hs * γm * Km * Kh 5) Filling mining method Pipeline features: Water Hf = ΔH + 1.05iL + Σhi Slurry Hmo = ΔΗγm + imL + Σhi Pump features: Slurry Hm = ΔΗγm + imL + Σhi Fresh water Hs = Hs * Km * Kh 6) Metallurgical mining law Pipeline features: Water Hf = ΔH + iL + Σhi Slurry Hmo = ΔΗγm + imL + Σhi Pump features: Slurry Hm = ΔΗγm + imL + Σhi Water Hs = Hs * γm * Kh Symbol and meaning in the formula Hf, Hmo, Hm, Hs pipe water head and the head of the slurry, the pump head and the slurry head lift; ΔH head loss; L pipe length; i, im water and slurry friction coefficient; Kh = 1-0.25Cw γm slurry specific gravity; Ko = H / (V ^ 2), water calculation pipe head and the square of the speed ratio. Vl critical sedimentation velocity. Km = Hm / (Vm ^ 2) slurry calculated pipe head and the ratio of the speed of the square.
