The SGMB140-7 diaphragm pump developed by Shenyang Metallurgical Machinery Co., Ltd. uses the pipeline equipment manufactured by Shanghai Meishan Mining Co., Ltd. to apply the long-distance pipeline transportation of solid-liquid two-phase medium. Recently, it passed the Chinese non-ferrous metal industry technology in Nanjing. Expert review by the Development and Exchange Center, Metallurgical Technology Development Center, and Science and Technology Evaluation Center of Liaoning Science and Technology Department.
Experts believe that all the domestically produced diaphragm pump series products and pipeline equipment have high continuous operation rate, safety, reliability and low maintenance cost. They are efficient, energy-saving and environmentally friendly products. The technology and equipment have solved the high concentration. The problem of large-flow and long-distance pipeline transportation of solid-liquid two-phase medium has filled the domestic gap; the overall performance of SGMB and DGMB series diaphragm pump products has reached the international level.
The diaphragm pump series developed by Shenyang Metallurgical Machinery Co., Ltd. successfully completed the tailings transportation with a distance of 12.5 kilometers after three years of production operation at Shanghai Meishan Mining Company Meishan Concentrator. It is the first time in China to carry out high-concentration, solid-liquid two-phase medium, large flow, and long-distance pipeline transportation. Shanghai Meshan Mining Company Meishan Concentrator uses diaphragm pump to realize high-concentration transportation transformation of tailings. Compared with before transformation, it saves about 500,000 cubic meters of water per year and saves about 1.014 million kWh of electricity. It saves more than 700,000 labor expenses. yuan.
According to Ling Xueqin, deputy general manager of Shenyang Metallurgical Machinery Co., Ltd., the diaphragm pump is an ideal equipment for solid-liquid two-phase medium transportation developed in industrialized countries in the 1970s. At present, there are only a few countries in the world such as the Netherlands and Germany. Ability to manufacture, but its products are expensive. Shenyang Metallurgical Machinery Co., Ltd. is the earliest manufacturer of diaphragm pumps in China, and successfully applied the products to the only manufacturers in the fields of metallurgy, chemical industry, mining and non-ferrous metals. In the chemical industry, the diaphragm pump series products have completed the industrial production assessment of coal-water slurry transportation, and have passed the appraisal of the former Ministry of Chemical Industry and other organizations. Currently, it has been obtained in the coal-water slurry transportation of Shandong Lunan Fertilizer Plant and Shanghai Coking Plant. Obvious benefits, praised by users.
Shenyang Metallurgical Machinery Co., Ltd. is a key backbone enterprise for large-scale mining and metallurgical equipment manufacturing in China. Since the early 1990s, the company has successfully developed a series of diaphragm pump products with independent intellectual property rights, which completely solved the pumping problem of high pressure, large flow and corrosive slurry, and made a new breakthrough in the application of slurry pipeline transportation. It ended the long history of similar pumps imported by China. The pump won the national new product award, the third prize of the former Ministry of Chemical Industry Science and Technology Progress, and the second prize of Liaoning Science and Technology Progress Award.
China's diaphragm pump market was almost occupied by HOLTHUIS in the Netherlands. Due to its high price, it greatly limited the application of this product. Therefore, experts from the judging panel composed of Northeastern University, Tsinghua University and the national authorities recommended that the diaphragm pump series should be vigorously promoted throughout the country. In addition to the current application areas, it should also accelerate its environmental protection, coal, light industry and chemical industry. Development and application in other fields of metallurgy, mining and other industries, and strive to enter the international market as soon as possible.
