What is a dynamic vacuum system?

Dynamic vacuum system refers to the system in which the pump still draws air when working, such as vacuum melting furnace, vacuum coating machine and particle accelerator.

Vacuum technology is widely used in various technological processes, such as vacuum melting furnace, RH vacuum treatment, vacuum spraying, vacuum distillation, vacuum concentration, vacuum welding, vacuum casting, vacuum coating, vacuum surface treatment, vacuum cathode ray tube, vacuum drying, vacuum bacteria, food packaging, solar energy development and utilization, particle accelerator, controlled nuclear fusion and aerospace.

The pumping system used to obtain and measure the vacuum degree with specific requirements is called vacuum system. There are many kinds of vacuum systems used in different technological processes, which are mainly divided into two categories.

One is the dynamic vacuum system, which relies on the continuous operation of the vacuum-obtaining equipment to continuously discharge the gas entering the system to obtain a stable vacuum. There is gas flowing in the system, and the pressure is different everywhere.

The second is a static vacuum system, which has no connection point with the outside world. After the vacuum is established, it can remain unchanged for a long time without vacuum pump, and the pressure in all parts of the system is equal.
