With the development of vacuum application, there are many kinds of vacuum pumps. Common vacuum pumps include dry screw vacuum pump, water ring vacuum pump, reciprocating pump, slide valve pump, vane vacuum pump, roots vacuum pump and diffusion pump. These vacuum pumps are essential main pumps in the application of vacuum technology in various industries of national economy. In recent years, with the continuous and high-speed development of China’s economy, the downstream application industry related to vacuum pump has maintained a rapid growth momentum. At the same time, driven by the continuous expansion of the application field of vacuum pump and other factors, China’s vacuum pump industry has achieved sustained, stable and rapid development.
Alibaba vacuum pump is a kind of rotary variable volume pump. The vacuum pump can be used with the cooperation of the front pump in a wide pressure range with a large pumping speed. It is insensitive to dust and water vapor contained in the extracted gas and widely used in metallurgy, chemical industry, food, electronic coating and other industries.
In the selection of Alibaba vacuum pump, the products to be determined shall be able to smoothly extract various gases released in the process. In the application process of vacuum pump, there are many kinds of gas medium, such as inflammable, explosive, condensable, easy to reverse and easy to corrode, so the applicability of the selected vacuum pump should be guaranteed. For example, the process will produce a lot of water vapor, the vacuum pump must be suitable for pumping steam.
The limit vacuum degree of vacuum pump must be higher than the vacuum degree required by process production, at least one order of magnitude higher, and the equipment is suitable for working within the required working vacuum degree range. The limit vacuum degree of vacuum pump is the vacuum degree that can be achieved when the pumping speed is zero. Therefore, in order to ensure the pumping speed of the vacuum pump in the working vacuum degree, it is necessary to meet the requirement that the limit vacuum degree is greater than the working vacuum degree, and a larger pumping speed is needed in the interval.
After hundreds of years of technical reform and professional development in the field of vacuum, a wide range of vacuum pump series, professional vacuum knowledge, and rich experience in the construction of vacuum system have created more types of vacuum pumps, which have made contributions to the development of industry and the progress of human civilization.
There are many vacuum pump manufacturers in China. The annual sales volume of all vacuum pumps is about 300 million yuan, which is only equivalent to the annual sales volume of a vacuum pump of an American company. Through the analysis of the global vacuum pump market, we can see that the market and application fields of various vacuum pumps are constantly changing and developing. This vacuum pump manufacturing industry has a long history and a solid foundation. The domestic vacuum pump has been applied and verified in various fields. The vacuum pump is exported to foreign countries, recognized and praised by foreign users. It should be said that China’s vacuum pump manufacturing industry still has a huge development space in the domestic and foreign markets.
