Ke Bingsheng, president of our university, director of China Agricultural Water Research Center, academician of Chinese Academy of Engineering, professor Kang Shaozhong and vice president Li Shuihu of Water Institute attended the conference.
Ke Bingsheng appraisal committee experts expressed his thanks. He said that the problem of agricultural water in our country is prominent, which is related to the country's food security. In recent years, our school's water conservancy disciplines have been widely recognized in recent years through their painstaking research and rapid development. The results of this appraisal are of great significance to ensuring water supply to agriculture and raising the rate of irrigation guarantee. He welcomed the experts from the appraisal committee for their valuable opinions. Kang Shaozhong briefly introduced my school water conservancy discipline.
Double suction centrifugal pumps are widely used in agricultural irrigation, inter-basin water diversion, urban water supply and other fields, especially in large-scale irrigation projects in northern China and long-distance high-lift water diversion project, almost all using large-flow double suction centrifugal pump. However, the large-flow double-suction centrifugal pump is generally pressure pulsating outstanding operating stability, high energy consumption and other issues. Our school cooperates with China Irrigation and Drainage Development Center, China Institute of Water Resources and Hydropower Research, Shanghai KSB Pump Co., Ltd., Shanghai Liancheng Pump Group Co., Ltd. and Shandong Shuanglun Co., Ltd. to reduce pressure pulsation, improve operation stability and broaden High efficiency zone as the main purpose. The related research work is carried out by theoretical analysis, numerical simulation, hydraulic model test, field test and pump station application. The calculation model and numerical solution of pressure pulsation in double suction centrifugal pump are put forward Pressure pulsation monitoring method and evaluation system, a hydraulic design method based on alternating blade loading technology was constructed, and engineering measures to reduce pressure pulsation and hydraulic loss were put forward. The research results in the Yellow River pumping station widely used.
The committee listened to the report of the project team and reviewed the related technical materials. After inquiring and discussing, the committee agreed that the achievement promoted the innovation of theory and technology of double-suction centrifugal pump in our country, which has important scientific significance and application value, Leading level, agreed to pass the appraisal.
Appraisal will be presided over by Hu Xiaosong, executive vice president of the Scientific Research Institute of our university, Yang Peiling, Party Secretary of the Waterworks Institute, Gao Mingyu, director of the Management Office of the Scientific Research Institute, etc., participate in the appraisal meeting.
"Large flow double suction centrifugal pump pressure pulsation control and energy-saving key technologies and applications of" scientific and technological achievements
On May 24, the Ministry of Education organized the Scientific and Technological Achievements Appraisal Conference of Key Technology and Application of Pressure Fluctuation Control and Energy Saving in High-flow Double-suction Centrifugal Pumps in Beijing . The appraisal committee unanimously approved the appraisal. This result was co-operated by six institutes such as our school, and the team of Professor Wang Fu-jun from Water College presided over this project.
