A vacuum pump is a device or device that uses a mechanical, physical, chemical, or physicochemical method to evacuate a pumped container to obtain a vacuum. In general, a vacuum pump is a device that uses various methods to improve, create, and maintain a vacuum in an enclosed space.

According to the working principle of the vacuum pump, the vacuum pump can basically be divided into two types, namely, a gas trap pump and a gas transfer pump. It is widely used in metallurgy, chemical, food, electronic coating and other industries.

Vacuum pumps include water ring pumps, reciprocating pumps, slide valve pumps, rotary vane pumps, Roots pumps and diffusion pumps. These pumps are currently the main pump types in the vacuum process of various industries in China's national economy. In recent years, with the sustained and rapid development of China's economy, the vacuum pump-related downstream application industry has maintained a rapid growth momentum. At the same time, with the continuous expansion of vacuum pump application fields and other factors, China's vacuum pump industry has achieved sustained and steady development.

China's vacuum pump market, the entry and success of foreign companies has become an indisputable fact, Japan vacuum around, Germany Bao expanded in China, and internationally renowned manufacturers such as American Taisier Group and South Korea Yucheng also sought partners to build manufacturing bases in China. Their appetite is very large, and there is a tendency for the whale swallowing vacuum pump market. In recent years, although some enterprises in China have gradually emerged and occupy a leading position in the vacuum pump market, most companies have poor R&D capabilities. Compared with their foreign counterparts, high-end products are still at a disadvantage in technology.

Vacuum pumps include dry screw vacuum pumps, water ring pumps, reciprocating pumps, slide valve pumps, rotary vane pumps, Roots pumps and diffusion pumps. These pumps are essential for the application of vacuum processes in various industries of China's national economy. In recent years, with the sustained and rapid development of China's economy, the downstream application industry of vacuum pumps has maintained a rapid growth momentum. At the same time, with the continuous expansion of vacuum pump application fields and other factors, China's vacuum pump industry has achieved sustained and rapid development.
