China's general machinery industry has made great progress, especially the technical level of pumps and valves, and can provide some medium and high-end products for the market, but some products are still imported. According to the data provided by China General Machinery Industry Association, the pump products with large import volume in China this year mainly include: hydraulic reciprocating piston pump, other hydraulic reciprocating liquid discharge pumps, rotary axial piston pump, other centrifugal pumps with rotational speed less than 10000 rpm, liquid pump parts, vacuum pumps, etc. Valve products mainly include: pressure reducing valve, hydraulic transmission valve, pneumatic transmission valve, safety valve or overflow valve, valve parts, etc. According to the analysis of the person in charge of China General Machinery Industry Association, there are four main reasons for this phenomenon.

　　First, R & D investment has been insufficient for a long time. There is an obvious gap between domestic enterprises and some foreign developed companies in the concept of product technology development. The insufficient investment of scientific research funds and R & D funds has become an important factor restricting enterprises' independent R & D. According to incomplete statistics of the water pump industry, the R & D capital investment accounts for less than 2% of the operating revenue of business owners. Compared with well-known foreign companies, the R & D capital investment of the whole industry is very small. Relevant statistics show that the annual R & D expenses of China's water pump industry are not as much as that of a foreign enterprise.

　　Second, the ability of independent innovation is weak. It is understood that the digestion and absorption of introduced technology in China's machinery manufacturing industry is slow, most enterprises have weak technological innovation ability, and 57% of the core technology sources of main machinery products rely on introduction. Although most products in China's water pump manufacturing industry have basically realized independent production and manufacturing, domestic enterprises mostly undertake the low-end processing links of products, and the breadth and depth of autonomy need to be improved. For example, most of its key core technologies still need to be imported, such as nuclear grade pump products in complete sets of nuclear power plants and high-pressure boiler feed pump core package products in complete sets of million KW supercritical and ultra supercritical thermal power plants.

　　Third, customers are less willing to buy domestic products. Although the performance index of domestic products has reached the same level as that of foreign products, some customers are still willing to buy foreign technical equipment, which makes it more difficult for the first set of domestic pump products with major technical equipment to enter the market. Although many domestic high-end pump products have considerable technical grade, some user departments still refuse to use them for reasons such as lack of operation performance. Fourth, there is a lack of research on industry common technology. Due to the restructuring, some industry-oriented research institutes have become independent enterprises, and the structure, nature and focus of work have changed greatly. Its industry technology support role is weakening day by day, the development speed of new technology and new process is slow, and it is difficult to connect with foreign standards such as design, process, material and manufacturing.

　　In this regard, relevant people put forward three suggestions: first, establish a new mechanism to encourage enterprises to innovate independently. According to the comprehensive planning and regional layout planning of the national pump and valve manufacturing industry, a number of regional leading technology and product development laboratories, test bases and product development centers will be built. Relying on scientific and educational institutions with strong innovation ability, establish scientific and technological achievement diffusion sites. Encourage and support the establishment of pump and valve manufacturing technology R & D center. Secondly, improve the technology promotion system. Reasonably set up grass-roots manufacturing technology promotion organizations, and gradually establish a diversified manufacturing technology promotion system dominated by national manufacturing technology promotion organizations, with division of labor, cooperation and services in place. In addition, we should improve the scientific and technological training system and the protection system of intellectual property rights. Establish and improve the connection between the training service functions of colleges and universities, scientific research institutions and secondary vocational schools and basic education, and give full play to the strength of institutions at all levels. Further improve the market environment for new product innovation, actively promote new product development, and enterprises and scientific research institutions establish and improve the management rules and regulations for independently developed new products.
