Investigation and analysis of water pumps, including multiple pumps for Chongzhou Steel, Zhangzhou Waterworks, Luzhou Natural Chemical Plant Water Plant, Yibin Paper Mill, and Panzhihua Iron and Steel Plant, due to increased sediment concentration in the flood season, and damage to the flow-through components Too fast and similar problems, especially the Panzhihua pontoon water pump impeller and the mouth ring are very abrasive and replaced frequently. In the flood season one month, two months, even days, ten days to replace the impeller, mouth ring, seriously affected Production and life requirements for water supply. After field tests, the hydrological and geological conditions were analyzed to observe the operating conditions and the characteristics of abrasion and damage during the flood season. A large number of studies on scientific and technological research in this field were conducted. Finally, the reasons were explained and countermeasures and directions were proposed. After several years of hard work, as a breakthrough, the serious abrasion and damage phenomena in the pumping operation of Panzhihua pontoon float pump were used to carry out the anti-abrasive modification and design of industrial pumps. Industrial trials have been successful, dialectical materialist inheritance, application and new development of cavitation. theory. Its promotion and application will have long-term potential economic benefits and important social benefits.
2 Operating conditions and erosion damage characteristics The water pump of the Jinsha River side pontoon in the power plant of Panzhihua Iron and Steel Plant is a sediment concentration. According to the statistics of the maximum sediment concentration in the Jinsha River for many years, it is calculated at 10kg/m3.
