Asia-Pacific Pump speed up the pace of development of large-scale cross-flow pum
HC Valve Network: Recently, the Asia-Pacific Valve Co., Ltd. Jiangsu, development and production of major dive Ministry of Science and other tubular pump was carried out by six ministries identified national key new products, while being included in the National Torch Program.
Tubular pump in foreign countries, particularly Japan and the Netherlands have been widely used. Japan since the late 60th century to the early 90's built more than 50 pumping stations have nearly run tubular pump station, the largest single flow of 11.5m3 / s, the maximum lifting height of 12.8m, head in more than 4m pumping a total of 28. Japan 1971 New River estuary pumping stations built by using 6 sets of pump, the total flow 24m3 / s, head 2.6m. The facts show that tubular pump technology in foreign countries has been very mature.
Valve Co., Ltd. Jiangsu Asia-Pacific since 1998, the development, production submersible pump, 2000, successfully developed a two-way S-type blade 45 kilowatts a tubular pump; 2001 to 2002 to produce 185 kilowatts consistent one-way blade flow pump 4 sets; in 2003 produced 3 sets of 560 kilowatts-way blade bevel gear and 4 sets of tubular pump 630 kilowatts-way blade pump, has passed technical appraisal, and put into operation; this year, Jiangsu Asia-Pacific has produced a 75 kW two-way blade and 132 kW, 250 kW tubular pump-way blade. Asia-Pacific Director of the Office, according to Chief Engineer
Wen-Jun Jiang introduced through the last few years on the tubular pump research, manufacture and production, Jiangsu accumulated much experience in Asia and the Pacific have also encountered many difficulties and lessons learned, developed for the next step Great pump laid a good foundation. Such as by creating 1400QGL-125-185 Direct tubular pump and 2000QGLC-100-560 Bevel Gear Drive Tubular pump model device Table Test with the conclusion that the front than the rear lamp bulb tubular pump efficiency high of 4% to 5%; tubular pumping has adopted S-blade and spindle leaves, S, high efficiency blades and some positive, some negative, high efficiency, which mainly depends on the linear leaves, leaf number and leaf thickness.
In addition, the bevel gear drive tubular axial pump is installed in the gear box to the center of the thrust bearing, if the use of planetary gear reducer, the axial force to the water pump located in the part of the thrust bearing affordable, high-torque for the pump, to be used only to promote W; the flow is greater than 6m3 / s, power is more than 600 to 800 kW or 24 above the motor pump, preferably gear.
Present, the domestic-built tubular maximum flow pumping station to pumping station in Jiangsu, single flow of 50m3 / s, a total of six sets of two parallel inclined shaft type gear box, electric power 1,600 kilowatts, gear power of 2400 kilowatts box. Maximum power of the tubular pump station for the Huai three stations, electrical power of 2500 kilowatts. Data show that the territory of South Jiangsu single tubular pump flow 20 ~ 37.5m3 / s, design lift 2.35 ~ 4.28m, the maximum lift 2.75 ~ 5.35m, electrical power is 1250 ~ 2500 kilowatts. These parameters pump, water design from the point of view, domestic enterprises are fully capable of design and development of power in 2500 kilowatts of tubular pump unit. Chairman of the Asia-Pacific Valve Co., Ltd. Jiangsu
often Lei believes that the Asia-Pacific has invested in domestic pump industry's largest submersible pump, tubular pump test center, follow closely the practical application of the product, so product quality is improving. Official with the technology, quality and service combined strengths, Jiangsu, a large submersible pump in the East Asia-Pacific deep-engineering, the Three Gorges Project and other national key projects, as well as Shanghai, Nanjing, Luoyang and other flood control and drainage in cities has been widely used; new Tubular pump clean water port in Shanghai, Jiangsu Huaihe River Sea and other water projects has been successfully applied, and play a good economic and social benefits. In the country, increasing infrastructure investment in the favorable opportunity, the Asia-Pacific in the product mix has grown from a single pump product developed to meet the national industrial policy, pumps, environmental protection, valves, dredging four pillar industries. The face of sound policy environment and market conditions, the company will be the conference as an opportunity to continue to increase product development efforts, to meet the different users, different conditions of pump demand, especially in a phased development of 10m3 / s, 15m3 / s and 20m3 / s of the large pump, and better services for the modernization of China's water conservancy.
