In pump selection work 250ZJ-I-A70 slurry pump, must refer to the pump performance curve to select a pump operating point 250ZJ-I-A75 slurry pump, for water pump, oil pump, chemical pumps, which do not convey abrasive Slurry pump operating point optional in the high zone, in order to improve the use of economic benefits; in the slurry pump slurry characteristics according 250ZJ-I-A68 slurry pump and pump life priorities premise , a reasonable choice pump operating point (see chapter VI), in order to improve the overall economic benefits of the use of the pump. Centrifugal slurry pump is a liquid (usually water) as a carrier to deliver a general machinery solid material, indicating that the pump performance parameter called the pump performance parameters, mainly in the following: 1. Traffic flow is the pump unit of time the number of discharged slurry with "Qm" indicates, the unit: m3 / S; m3 / H; e / s by liquid slurries (typically water) and solids mixture, so flow slurry QM is equal to Qm = Qw + Qs (1-1) Where: Qw- liquid (water) flow m3 / S; m3 / H; e / s Qs- solid logistics volume m3 / S; m3 / H; e / s 250ZJ -I-A65 slurry pump, Shijiazhuang (certified), slurry by Shijiazhuang-Pump Co., Ltd. faction. Shijiazhuang-school Pump Co., Ltd. (www.shipaipump.com) is Shijiazhuang, other leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
