With the rapid economic development of the world, water resources increasingly important strategic position, attaches great importance to the efficient use and effective management of water resources has been more governments around the world. China is a large agricultural country, water conservancy big country, water occupies a pivotal position in the development of the national economy.The pump station-water only artificial power source, pumping stations based on their role is different, can be divided into the type of electromechanical irrigation and drainage pumping stations, urban water supply and drainage pumping stations, industrial water supply pumping stations and booster stations. As important engineering measures, it plays an irreplaceable role in the rational management of water resources and management.With the continuous improvement of the level of the pump unit design and manufacturing technology, large capacity pump unit, large and medium-sized pumps stand of applications is increasing. Many provinces of the Yangtze River, the Yellow River Basin Water Conservancy province, due to the needs of economic construction, often tens of thousands or even hundreds of thousands of kilowatts installed capacity of large pumping station built. These pumping stations the running generally have a number of operations, and start and stop frequently. Pumping station, it has both the pumping unit to optimize the scheduling requirements of the same area or the same optimal scheduling in the watershed between the different pumping stations. These large and medium-sized pumps are also faced with the issue of reliability, stability, security and economic standing in the run. |
