Spark national projects products topology high-lift pump, made recently in Gansu. The 4 kW motor pumps using a lift would allow more than 100 meters, the flow of 6 tons per hour.
The main R & D units in Gansu pump topology pump Ltd. Wang fame, popular use of traditional centrifugal pump efficiency often only around 30%. Even through the use of multi-stage high lift pump, the highest efficiency of more than 50%. Topology and single pump in 60-80% efficiency. Therefore, in the same flow with the head of state, usually only centrifugal pump topology pump power required 60% 40% more efficient.
"Ordinary centrifugal pump is very difficult to achieve high-lift. "Said Wang fame, the single pump, in order to lift more than 100 meters. at least need to be equipped with the 22 kW motor, and by using multi-stage pump, the cost would raise the price three times. The use of small power motors lift higher, the domestic pump industry has been plagued by a major technical problems.
In order to overcome this international problem, topological pump Limited, Lanzhou University, China Agricultural University, Lanzhou, the Hong Kong Polytechnic University, Physics of the CAS Lanzhou units and technical experts work together lasted 11 years. eventually develop high-tech products with independent intellectual property rights of high-lift pump topology. The project received national patents for inventions in 2003, was included in the same year, Gansu Province, a major technical innovation projects SME Innovation Fund projects include the state's key new products in 2004, 2005 included national Spark Program
. "Drought has been restricted in parts of the country. Particularly in the northwest, one of the important factors of socio-economic development. "said Wang fame, topology pump low consumption, efficiency of the same small size, light weight, good applicability of using a wide range of fields, lower manufacturing costs and operating costs. limited water resources in China's western region will be more effective. Moreover, the topology can be used for pumping oil, transmission fluid, such as liquid chemical, municipal engineering, water conservancy construction. chemical engineering, petroleum engineering and many other fields lot. WANG Cheng said that as part of the traditional area of general machinery and high-tech equipment, professional substitute, Topology pump enormous potential market, the domestic market is expected to be achieved by 2007 only 40 billion yuan.
