"Made in China" swept the world, and vacuum pump industry is no exception. Compared with the European and American vacuum pump industry, the national vacuum pump industry has both advantages and disadvantages.

Compared with the European and American vacuum pump industry, the national vacuum pump industry has two advantages. First, low cost is the competitive advantage of China's vacuum pump industry. The salary level of China's labor force is 3 US dollars less than that of European and American per capita every day. Most enterprises recruit technicians from villages in other places, and the factory building is the school building for technicians, so as to reduce the cost. The exchange fee for leasing or building factory buildings is also lower than that for building factories in European and American countries. Moreover, the rapid growth of China's construction, petroleum, petrochemical and environmental protection markets and major water diversion projects have also provided a key defense for the development of China's vacuum pump industry. It can be said that the continuous growth of China's market space is the prerequisite for China's vacuum pump industry to maintain its advantages.

However, these advantages are caused by the external environment of the enterprise, and are not formed by the core competitiveness of the enterprise. Similarly, they can not constitute the core competitiveness of the enterprise. Compared with the European and American vacuum pump industry, there is still a very big gap in the national vacuum pump industry.

The first is that the design ability can't keep up. Some state-owned heavy-duty enterprises in China can now produce spare parts for overseas vacuum pump enterprises. These enterprises have advanced computer data manipulation polishing core and CNC sawing machine, computer aided design, coordinate mapping and other facilities. However, these facilities are rarely used to polish domestic goods. This also hinders the adjustment of the design capacity of China's vacuum pump industry. As a result, the design capacity of most domestic vacuum pump enterprises will only satisfy the domestic market.

The ability of skill innovation is insufficient. At present, many vacuum pump enterprises at home and abroad have introduced very few advanced skills to do innovation. When overseas users visit China's heavy industrial projects, such as papermaking, petrochemical, etc., they find many vacuum pump products for many projects. However, the design prototype in Europe and America has basically been adjusted according to the nominal system and German industrial standards. As a result, it is very difficult for vacuum pump companies to export their products to European and American markets.

The polishing process is blocked. Although some domestic vacuum pump manufacturers have modern facilities to realize automatic operation, even the forging enterprises in Europe and America are dwarfed. Most of the old enterprises have poor working environment. Nowadays, China's vacuum pump enterprises can forge vacuum pump products of aluminum, copper, cast steel, cast iron, 304 and 316 stainless steel and composite materials. However, due to the blocking of forging technology, cast steel and cast iron materials are widely spread in the production process.

In order to solve the problems existing in the vacuum pump industry all over the country, the state has also stipulated some guidelines. As Wang Anshen, chief project engineer of vacuum pump industry branch of China General Machinery Industry Association, issued by the state, the state has put forward the national policy of exchanging skills with the market, and cooperate with foreign parties by means of "transfer of skills, joint design, cooperative manufacturing", and so on. At the same time, it should ensure that domestic enterprises have sufficient color separation ratio, so that domestic enterprises can control complete R & D and manufacturing skills. In this situation, China's vacuum pump industry should seize the opportunity to catch up.
