Keshen Pump Factory has developed a variety of specific speed axial flow pumps

The China Water Resources and Hydropower Research Institute Kezhen Pump Manufacturing Plant has developed a variety of hydraulic models for specific axial flow pumps and axial flow pumps, and has produced a series of high-efficiency energy-saving axial flow pumps. After identification, the technology has reached the domestic leading level and the international advanced level. It has won two national science and technology progress awards and three water conservancy science and technology progress awards. On this basis, it has developed a new two-way submersible flow pump unit.

In response to the actual demand for positive and negative two-way pumping in some urban flood control pumping stations, combined with the development experience of the two-way axial flow pump, the plant successfully developed a two-way submersible tubular pump unit. The plant developed and produced the Nenjiang River 450SHGB bidirectional cross-flow pump unit for Shanghai Shenpu Foundation Engineering Co., Ltd., and passed the test and acceptance of the prototype full-flow pump of the prototype pump jointly organized by the China Irrigation and Drainage Development Center.

Developed the Shanghai Yangshupugang pumping station-two-way submersible pumping unit technology, which is a key project of river regulation in Yangpu District, Shanghai. It is responsible for the drainage of the Yangshupu Port water system and the water diversion from the Huangpu River. The task of pollution.

The small data bidirectional tubular pump unit is a new and practical pump type, which has the characteristics of smooth flow path of the cross flow pump and simple pump structure. The cross-flow pump of the "S"-shaped blade can realize two-way pumping when the motor is running in the forward and reverse directions, and the efficiency is high. The efficiency of the pump station is close to one-way operation, and the operation and management are convenient. The two-way cross-flow pumping station is set in a semi-underground, which can meet the requirements of urban landscape planning, save 30% to 40% of the investment in civil construction and pumping station construction, save 30% to 40% of the floor space, and maintain the long-term water consumption of the entire water system. Intermittently flushing the entire water system with significant economic and social benefits.

The two-way submersible flow pump unit can be widely used in pump stations with two-way operation along the river and coastal low lift.
