What is axial flow pump?

The use of impeller rotation on the water thrust (lift) work, is a large flow low-lift pump, vertical, horizontal, inclined and tubular flow several. China has successively developed 664 sets of large-scale axial flow pumps since 1961. The specific rotational speed n is 500, 700, 850, 1000, 1250, 1400, 1600 and so on. The diameters of the wheels are 1.6m, 2.0m, 2.8m, 3.0m, 3.1m, 4.0m and 4.5m. There are 114 large-scale axial-flow pump stations built in 16 provinces, cities and districts in Jiangsu, Hubei, Hunan, Anhui, Guangdong, Tianjin, Shandong, Shanxi, Shaanxi and Xinjiang, with a total installed capacity of 630,000 kW. Japan, the Soviet Union, the Netherlands, Germany and other countries, the development of high-level axial pump. Japan's Nikko River pumping station axial flow pump, diameter 4.6m, flow 50m3 / s, lift 5m, speed 95r / min, supporting power 4260kW, efficiency 90%, is the world's largest axial flow pump.
