Failure (1) pump does not turn; insufficient (2) pump flow; (3) the padding leak; (4) pump vibration, noise; (5) bearing heating; short (6) bearing life. Vertical slurry pump manufacturers. ΔH head loss; L pipe length; i, im water and slurry friction coefficient; Kh = 1-0.25Cwγm slurry specific gravity; Ko = H / (V ^ 2), calculate the ratio of water pipeline and the square of the speed of the head . Zhaoqing slurry pump manufacturers. Vl critical settling velocity. Km = Hm / (Vm ^ 2) slurry pipeline to calculate the ratio of head and velocity squared. Slurry pump parameters: Flow: 50 to 1800 cubic meters per hour Head: 24 ~ 94 meters HEAD: 24 ~ 94 米 Capacity: 17 ~ 1267 cubic meters per hour motor power: 11 ~ 710kwMotor power: 11 ~ 710kw Product Standard: JB / T8096-1998
