Coal-water slurry diaphragm pump successfully achieved domestic manufacturing

Thread Content

The coal-water slurry diaphragm pump is one of the key equipment in the coal chemical industry. It has high technical difficulties and has long relied on imports. It is predicted that by 2020, 2,000 Texaco gasifiers of various specifications will be added across the country, requiring 2,000 high-pressure pumps and 4,000 low-pressure pumps. 　　Based on the development of the first generation of high-pressure coal slurry diaphragm pumps, Zhongshe Machinery Company applied modern CAE technology, established a technological innovation system with independent intellectual property rights, and independently developed a series of high-pressure coal slurry pumps and low-pressure coal slurry pumps with independent intellectual property rights that are at the internationally advanced level, and applied for 5 awards. * * patent. It is characterized by advanced design, reasonable structure, mature and reliable manufacturing process, overall technical parameter matching technology, rubber diaphragm technology, heavy-duty crankshaft structure, magnetic signal sensor detection technology, automatic control technology, high-pressure sealing technology, etc. It is technologically innovative and solves the key technical issues of high continuous operation rate under harsh working conditions. The product fills the domestic gap. 　　The project on which the diaphragm pump of the sinker is based - the single gasification unit of Sinopec Nanhua Company's large fertilizer has a daily coal consumption of 1500t and a gasification pressure of 8.5MPa. It has the highest gasification pressure in the world and is the only coal chemical Texaco gasification unit put into industrial operation. Its technical level represents the current international advanced level. Among them, the design and manufacturing tasks of low-pressure coal slurry pumps for the raw material structure adjustment project are undertaken by China Color Precipitation Machinery Company. By October 2007, two low-pressure coal slurry pumps had completed 20 months of industrial operation assessment. ； A high-pressure coal slurry pump has continuously completed the assessment of three complete industrial operation cycles of 4,500 hours, and is currently undergoing the fourth cycle of industrial operation. The successful operation of the first (set) diaphragm pump has filled a domestic gap and marked that my country's high and low pressure coal slurry pump technology has reached the current international advanced level. It is of great significance to the development of my country's coal chemical industry and the advancement of equipment manufacturing technology.
