Approach and Realization of Energy Saving Technology Innovating at the Pump Station Wang Zhao-han 1, a, Xuan Chang-guo 2,b 1 Wang Zhaohan School of Civil Engineering and Architecture University of Jinan Jinan, Shandong, China 2 Xuan Changguo Shandong Hi-speed Group Co Ltd Jinan, Shandong, China a moon1989@163.com, b lbfyh@sina.com Keywords: pump station, energy saving; measures Abstract.Rapid increase of energy consumption greatly restrains China’s sustainable development.
Renovation Measures for Energy Saving 2.1 Expansion of Irrigation Area Expand proactively the irrigation area based on current water resources and irrigation area situation to improve the availability of the motor and make use of the engineering benefits. 2.2 Enlargement of the Suction Pipe Diameter and Turning of Impeller To solve the difficulty of water diversion in spring, the diameter of water pipe is enlarged from 500mm to 700mm to reduce the head loss in the water suction pipe and improve the suction ability of the water pump.
Meanwhile, this method is clear in theory, simple in method and easy in operation, thus it has certain application value in engineering practice and it can be applied to evaluation of water environment quality, bearing capacity of regional water resources and other fields.
