Francis pump from the shape, the structure is between centrifugal and axial flow pump; Francis pump pumping principle of mixed-flow pump, high-speed rotation 150HW-8 mixed-flow pump impeller produces both centrifugal centrifugal force also has axial flow Push lift, Francis pump by mixing these two forces and pumping. Mixed-flow pump performance is somewhere between centrifugal and axial flow and centrifugal compare it, head lower 200HW-5 mixed-flow pump, and flow larger; it is compared with the axial flow, high lift, but the Traffic and smaller. This is a vast territory, complex terrain 200HW-4 mixed-flow pump, and more choice of a pump adapted to local conditions. By blade axial flow impeller rotating wheel to force the liquid produced by the liquid in the axial direction of the delivery of the pump, vertical, horizontal, inclined and Tubular several species. China since 1961 has developed a total of 664 sets of large axial flow pump. Its specific speed n are 500,700,850,1000,1250,1400,1600 like; runner diameter of 1.6m, 2.0m, 2.8m, 3.0m, 3.1m, 4.0m and 4.5m. In Jiangsu, Hubei, Hunan, Anhui, Guangdong, Tianjin, Shandong, Shanxi, Shaanxi, Xinjiang and other 16 provinces, municipalities and autonomous regions to build a total of 114 large axial flow pump station with a total installed capacity of 630,000 kW. 200HW-4 mixed-flow pump, Francis pump, price Ltd provided by the Shijiazhuang-send pump. Shijiazhuang-school Pump Co., Ltd. (www.shipaipump.com) strong, credible, and other industries in other Shijiazhuang, Hebei accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Shijiazhuang-faction pump into the brilliant and you work for a better future!
