In a vacuum system, the vacuum is for the atmosphere. A certain space or part of the gas in the system is exhausted, and the pressure of the internal space is less than the atmospheric pressure, then the space is called a vacuum or vacuum state, in short , The pressure in the space is lower than one atmospheric pressure, which is a vacuum.

According to the above definition, vacuum technology can be simple or difficult. For example, vacuum cleaners use the vacuum principle, but the high vacuum and ultra-high vacuum required in high-tech manufacturing processes must have sufficient vacuum technology and Equipment can be achieved.

The degree of vacuum represents the degree of remaining gas in a vacuum system, usually measured by the pressure of the remaining gas, and the degree of vacuum is generally distinguished as follows:

Rough vacuum: 1000-1mbar, medium vacuum: 1-10-3mbar, high vacuum: 10-3-10-7mbar, ultra-high vacuum: 10-7-10-10mbar, ultra-high vacuum: Below 10-10mbar.

Daotian Vacuum focuses on semiconductor, aerospace, biomedical technology and many other industries. With technology as the development direction, through cooperation with domestic and foreign industry giants and domestic scientific research institutions, it has deep technical precipitation and achieved international synchronization of technology. Localization, service localization, and strong independent development and manufacturing capabilities.

The vacuum system is composed of a vacuum pump as a vacuum source, corresponding vacuum valves, vacuum instruments, intelligent electric control boxes, vacuum tanks, filters, etc.

Daotian can design according to customer's process and usage requirements, or customize it according to drawings.
