目前,苏联每年生产几十万台离心泵,这些泵每年耗电2000亿度以上。因此,如何进一步改进离心泵,提高其效率和扬程,乃是一个很重要的问题。解决这个问题就能节省电力及金属耗用量。例如,单是全苏火电站的给水泵和冷凝水泵,只要提高效率1.5%,每年即可节电10亿度;每台泵的扬程只要提高15%,金属耗用量即可节省 At present, the Soviet Union produces hundreds of thousands of centrifugal pumps every year, and these pumps consume more than 200 billion kilowatts each year. Therefore, how to further improve the centrifugal pump to improve its efficiency and lift is a very important issue. Solve this problem can save electricity and metal consumption. For example, a single feed water pump and a condensate pump at the All-Su thermal power station can save 1 billion kWh of electricity each year by increasing efficiency by 1.5%. As long as the lift of each pump is increased by 15%, the consumption of metal can be saved
