The current situation of China's pump industry and the gap with the world level
2021-07-26
Domestic Development Overview: In recent years, China's pump industry has seen rapid development. However, most Chinese pump manufacturers are small-scale, with slow product updates and subpar quality, lagging significantly behind their foreign counterparts in many aspects. Currently, there's an oversupply of ordinary industrial pumps, while high-level, high-quality specialized pumps are in short supply, necessitating imports. A considerable gap exists between product quality and user demands. The industrial and product structures are particularly unbalanced; very few products reach the world's leading standards, with most only achieving the level of the late 1980s and early 1990s, failing to meet evolving market demands. There's a serious product backlog alongside a shortage of urgently needed products due to slow trial production, hindering a break from traditional product models. The gap with foreign technologies remains, and the situation is concerning. Pump station design is limited to a few similar-performing standardized products, reducing efficiency and creating safety hazards. Most Chinese water pump manufacturers are small-scale, lacking high-precision processing and testing equipment. New processes, materials, and technologies (including CAD/CAM) haven't been widely adopted.
Foreign Development Overview: Foreign pump development is faster and technologically more advanced. Large foreign pump manufacturers produce pumps with high speeds, small sizes, and light weights, with flow rates 1.5 to 2 times higher than comparable Chinese pumps. Countries like the Netherlands, Japan, the United States, and the former Soviet Union show significantly superior pump performance. The Netherlands, in particular, emphasizes research and development, boasting strong research capabilities, advanced facilities, and systematic studies of pumps and their inlet/outlet flow paths. Industrially advanced nations offer valuable design, manufacturing, and research practices for us to learn from. However, they also face challenges in improving key parameters like pump head and flow rate, requiring further investment in mechanical structure improvements. Globally, the pump industry is moving towards larger, faster, stronger, higher-pressure, more reliable, longer-lasting, system-controlled, and integrated electromechanical pumps. Longevity, reliability, and automation are now key selection criteria.
