Section Yu pump factory developed a variety of speed than the axial flow pump

China Institute of Water Resources and Hydropower Research Branch Yu pump factory developed a variety of speed than the axial flow pump and axial flow pump device hydraulic model and produce a series of energy-efficient axial-flow pump products. It has been identified that the technology has reached the leading domestic and international advanced level and won two national scientific and technological progress awards and three water conservancy scientific and technological progress awards. On this basis, a new type of two-way submersible tubular pump was developed. In view of the actual demands of both urban pumping stations and flood pumping stations in some cities, combined with the previous experience of bidirectional axial flow pumps, the plant successfully developed two-way submersible turbine units. The plant for the Shanghai Shanghai Pu Foundation Engineering Co., Ltd. to develop and produce a combination of gate station Nenjiang 450SHGB-type two-way tubular pump unit, adopted by the Chinese irrigation and drainage Development Center and other units of the prototype pump full runner test acceptance. Developed Shanghai Yangshupu Port Pumping Station - Bidirectional Submersible Turbine Pumping Unit Technology, a key project of riverway management in Yangpu District of Shanghai, undertaking drainage and drainage of Yangshupuang River and carrying out water diversion from the Huangpu River to the entire water system Chong pollution task. Two-way small information flow through the pump unit is a new type of practical pump, with smooth flow through the pump, pump structure is simple and so on. The "S" -shaped tubular cross-flow pump can realize bi-directional pumping when the motor is operating in forward and reverse direction, which is more efficient and more efficient than the one-way operation and convenient for operation and management. Two-way tubular pump station set in the semi-underground, to meet the requirements of urban landscape planning, saving construction and pumping station construction investment 30% to 40%, saving 30% to 40% of land area, to maintain long-term water throughout the water system, not Intermittent pollution of the entire water system, significant economic and social benefits. Bidirectional diving tubular pump unit can be widely used in pumping stations along the Yangtze River, coastal low-lift two-way operation.
