China's largest marine diameter in a pump assembly line factory

   Recently, Hunan landscape Energy Saving Technology Co., Ltd. announced the news, the company developed the first station 76 tons of professional marine sand pump off the assembly line factory. Its flow up to 18000m3 / h, is a professional marine China and the world's largest diameter in a pump. The product can be widely in the petrochemical industry and many other areas. This indicates that China fluid areas of energy equipment manufacturing capacity, new breakthroughs.

According to the company's chairman Qu Yingjie introduction, this professional-grade sand pump high flow, high head an hour inhalation of water can fill 12 volumes of 1500m3 common pool, head up to 145m to 160m. Impeller diameter 2.38m, speed up to 410rpm, impeller single weight 6.7 tons, pumps single weight 41 tons, the overall pump weight up to 76 tons.

Chief Engineer Sun Mingxia told reporters, this large sand pump manufacturing process, the company's design, casting, machining, installation and debugging capabilities have received a huge challenge. Engineering and technical personnel use Ansys structural strength analysis and advanced CFD data analysis, conducted sophisticated product design and technology optimization through manufacturing excellent manufacturing processes with, one by breaking the design, mold making, casting, machining, assembly , part of the matching process six technical difficulties. Sun Mingxia said to ensure superior product quality and stable performance, the designer through finite element analysis on the performance, strength and structure has been designed to optimize. Best match flow, pressure parameters, increased sediment yield pump; well-designed pump selection with the gap and reasonable material selection prolong pump life, reducing maintenance disassembly time; Large diameter spindle design, guarantee pump has sufficient rigidity to cope with various use of harsh working conditions, and compare the actual test results of the analysis by CFD modeling pump, the final results were in agreement. Meanwhile, in order to fully meet the customer's individual requirements using special conditions, and other large motors, pumps in the design and manufacture has also increased the number of complex matching process to ensure that the pump regardless of the engine speed high or low speed
