China's apparent consumption of vacuum pumps has reached a level close to 1 / 4 of the global total consumption, and the per capita consumption of stainless steel has reached 3.4kg, leaping to the forefront of developing countries. Stainless steel pump has excellent characteristics such as corrosion resistance, high strength, portability and long service life. In recent years, stainless steel pumps are widely used in shipbuilding, rail vehicles and other transportation industries. Let's get to know each other. With the development of machinery manufacturing industry, stainless steel pump will have a broader application prospect. However, the growth rate of consumption has gradually slowed down, from the rapid development stage with an average annual growth rate of more than 30% to the steady development stage with a current growth rate of 6.43%. Although the development of the vacuum pump industry has been relatively stable for a long time, its competition is still not standardized. There are mainly the following problems: first, some operators buy Valves with manufacturer's name and address, or print the certificate of well-known manufacturers, which misleads consumers and seriously endangers the reputation of qualified valve enterprises. Second, some operators carry out secondary sales after refurbishing and repainting waste valves, which brings serious potential safety hazards to the project quality and seriously disrupts the order of the valve market. I believe many customers already know about the vacuum pump. If there is anything you don't know, you can learn from our website at any time, or call our hotline to learn more about it.
