In recent years, China's pump industry has been rapidly developed, but most of China's pump manufacturing enterprises are not large scale, product update is not fast enough, the quality is not high enough, in many aspects and foreign pumps have a big gap. At present, the supply of general products of industrial pumps exceeds the demand, and the supply of special products of high level and high quality exceeds the demand.
Domestic development overview: in recent years, China's pump industry has been rapidly developed, but most of China's pump manufacturing enterprises are not large scale, product update is not fast enough, the quality is not high enough, in many aspects and foreign pumps have a big gap. At present, the supply of general products of industrial pumps exceeds the demand, and the supply of special products of high level and high quality exceeds the demand. The unreasonable phenomenon of industrial structure and product structure is particularly obvious. Few products have reached the advanced level of the modern world, most of which only reached the level of the late 1980s and early 1990s, and cannot adapt to the change of market demand structure. On the one hand, the product backlog is serious, on the other hand, the urgently needed products in the market are too slow or in short supply to break the pattern of traditional products. The dynamic gap with foreign countries has not narrowed, the situation is not optimistic. In the design of the pump station, only a limited number of products with similar performance can be selected, which not only reduces the efficiency of the pump station, but also leaves many unsafe risks. Most of the water pump manufacturing enterprises in China are small in scale and lack of high-precision processing and testing equipment. New processes, new materials, new technologies (including CAD/CAM) have not been widely promoted and applied.
The status quo of China's pump industry and the gap with the world level
Overview of foreign development: foreign pump development speed is faster, more advanced technology. The pump produced by large foreign pump manufacturers generally has the advantages of high speed, small volume and light weight, and its flow rate is 1.5~2 times that of the same caliber pump in China. Especially the Netherlands, Japan, the United States, the former Soviet union and other countries, pump performance index is obviously better than the domestic. The Netherlands pays more attention to the investment of scientific research, its scientific research strength is very strong, the facilities are relatively perfect, the water pump and its inlet and outlet channel have a comparative system of research. Abroad, especially the industrial level is relatively developed countries, they in design and manufacture of pumps and the importance of research on water pump, indeed worthy of our learning and using for reference, but is not to say that they are in the field of water pump design and manufacture of perfect, also need the pump lift and flow rate on the important parameters, such as make a step, which requires the water pump mechanical structural improvement on the input power. With the development of science and technology, the pump industry at home and abroad to large-scale, high-speed, high strength, high pressure, high reliability, long life, system control and integration of machinery, electrical equipment and other high-tech development direction, among which, life, reliability and automation has become the main factors when choosing the pump.
