According to national statistics, power consumption of pump products accounts for about 20% of the country's total generating capacity, accounting for 5% of the total fuel consumption. Therefore, to strengthen the pump industry energy-saving technology, without delay. Pumps (Pictures from the Internet) To improve the operating efficiency of a pump product, we must first improve the design efficiency of the pump itself, develop advanced hydraulic design and performance prediction software by strengthening the study of the internal flow of the pump. At the same time, we must also vigorously improve the energy-saving pump operation and management level, because the pump run time if deviate from the design of efficient points, the actual operating efficiency will be very significant decline. Therefore, adopting the internationally advanced three-element flow impeller technology, there is a vast space for energy saving in the circulating pump, and the present energy-saving technology of the three-element flow impeller is mainly used in the following fields: (1) Large-scale circulating water system The system is mainly distributed In petrochemical enterprises, large steel mills and other cooling water system (cooling towers), the system generally use large and medium-sized double suction pump, pump flow, power. For a long time, on the one hand, due to the too conservative selection, the pump head and the flow double deviate from the actual demand of the unit. On the other hand, due to the adjustment of the equipment parameters, the water and pipe network pressure needs to be adjusted, and the difference between winter and summer conditions . (2) Large and medium-sized pumping station construction and renovation project Through the construction of national South-North Water Diversion Project, Changsha Pump Factory and Jiangsu University insisted on the theory and experimental research of axial flow pump and diagonal flow pump in recent ten years and studied the series of high efficiency axial flow pump ns = 500-1600), diagonal flow pump (ns = 350-850), cross-flow pump hydraulic model, bi-directional pump hydraulic model, the efficiency of about 5% higher than similar models in the 1980s. (3) Other high-energy pump system engineering Pumps as a general machinery, a wide range of applications, for energy-saving pumps, the first consideration to transform high energy consumption, high rate of return pump system. The annual operation of 8400 hours, the energy consumption of more than 200kW / h pump system should be the focus of the transformation of the object, if through the transformation of energy-saving 10%, the annual rate of return is very impressive.
