Your participation in the discussion serves as the greatest motivation. ********************** [Ten Years of Great Development in Chemical Equipment] This is a continuously updated summary thread; all are welcome to join the discussion: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** On April 10, at the production site of a certain mining enterprise (hereinafter referred to as the “Mining Company”), a 25 MPa ultra-high-pressure diaphragm pump jointly developed by Chongqing Pump Co., Ltd. and the Mining Company successfully underwent a crucial technical validation. This device has successfully achieved long-distance transportation of 99 kilometers of iron ore concentrate using a single unit. In the 72-hour continuous operation test, all its key performance parameters exceeded those of foreign high-pressure diaphragm pumps, marking a significant breakthrough in China’s field of high-pressure diaphragm pumps and indicating that its overall technology has reached international advanced levels. 　　The 25MPa high-pressure diaphragm pump delivered this time is the first set of equipment to be used in practical applications in China, and it represents the results of five years of technical research and development by Heavy Pump Company. Since its initiation in 2020, the company established a cross-departmental R&D team that, through nearly a hundred rounds of technical consultations with users, optimized the product’s adaptability to various operating conditions. As a result, 11 intellectual property rights and 6 technical achievements were developed, with key breakthroughs achieved in six core technical areas:
· Optimization of technical parameters for ultra-high pressure diaphragm pump units
· Research and application of properties of metallic and non-metallic materials
· Intelligent oil replenishment technology for high inlet/outlet pressure conditions
· Structural design and manufacturing processes for large-diameter, high-pressure special-shaped pressure components
· Solutions to improve the reliability of large-diameter high-pressure dynamic sealing systems
· High-precision bearing assembly techniques and systems to ensure long-term operation
The successful deployment of this equipment not only broke the foreign technological monopoly but also served as a model example for the autonomous development of mining transportation equipment in China.
