Analysis of the gap between domestic pump industry and other countries

Weak scientific research and development, insufficient capital investment, and slow technological progress In the late 1970s and early 1980s, the valve parts industry of the basic components introduced a number of foreign advanced technology forged steel valves, but lacked enough for digestion and absorption. Software and hardware investment. According to foreign experience, the ratio of imported technology and the funds required for digestion and absorption is about 1:7, and China is familiar with this later, and its digestion and absorption steps are slow. Market competition is actually a contest of technical strength. Foreign countries attach great importance to this and have increased investment to occupy the commanding heights of technology. The capitals used by major famous companies for scientific research and development accounted for 4 to 5 of their sales, and the key leading hard seal butterfly valve domain reached 10. Although many anti-corrosion valves for universities in China are currently engaged in scientific research, many theoretical researches, scientific research achievements, and patent papers have a fairly high level, but the actual combination with production is not tight, and the conversion to commodities is unusually slow. Forged steel valve.

The backwardness of raw materials and related technologies, the low level of technology and equipment, and the restrictions on the development of the basic parts have resulted in poor quality of the steel used in fasteners, chains, springs, bearings, molds, and other products, and have had a direct impact on the basic parts. The quality, and the backwardness of the hydraulic control castings and the electronic control technology related to the quality of the hydraulic parts, also directly affect the quality of hydraulic parts and reliable forged steel valves. The mechanical basic parts are generally mass-produced, mass-produced, and also have many varieties and high precision machining products. Therefore, the chemical valves have high requirements for the production process and equipment, and the investment is large. In many foreign countries, high-efficiency and high-precision special planes, production lines or flexible lines are used to achieve efficient and automated production. However, some basic parts companies in China are restricted by funds, their input is not strong, their self-reforming ability is poor, and their advanced equipment is small and unmatched, affecting the quality of the products on the forging steel valves.
