Why Quantum Technology Cannot Be Separated from Vacuum?

Structure of Dry Screw Vacuum Pump The Working Principle of Screw Vacuum Pump A pair of parallel helical rotors are installed in a dry screw vacuum pump, one of which rotates clockwise while the other rotates counterclockwise. The two rotors are kept in synchronous opposite rotation by a pair of gears inside the pump body. There is no friction between the rotors and between the rotors and the pump body, and there is a certain gap between them. The two rotors and the pump body form a sealing cavity, and the number of sealing cavities is equal to the number of rotation rings of the rotors.

The essence of a vacuum pump is to evacuate gas from a sealed space through various methods, thereby reducing pressure (creating a vacuum). Based on the different "evacuation methods," they are primarily classified into four categories:

Top Vacuum Socre brings you a new solution for optimizing valve selection. In vacuum systems, vacuum system components used to change the direction of airflow, adjust the volume of airflow, cut off or connect pipelines are called vacuum valves. The functions of vacuum valves in vacuum systems are: switching air paths, changing the flow route of airflow; controlling the volume of airflow, adjusting the vacuum degree; and quantitatively inflating. Vacuum valves mainly include vacuum angle valves, vacuum ball valves, vacuum butterfly valves, vacuum diaphragm valves, vacuum gate valves, and vacuum globe valves. Different types of vacuum valves have different applications. Below, we will discuss the characteristics and common areas of use of different types of valves such as gate valves, globe valves, butterfly valves, and ball valves. When configuring and selecting vacuum valves, it is necessary to consider the minimum pressure difference and high flow resistance of components within the molecular flow range. In addition, the valve body and valve seat require the minimum leakage rate. The lubricant on the vacuum side of moving parts in the valve must be suitable for the required pressure and temperature range, or overall exposure to high or ultra-high vacuum should be avoided as much as possible. The minimum harmful (dead) space and large flow conductance are important, especially in the molecular flow range.

1. Select the valve type based on the vacuum level The first principle in valve selection is vacuum level matching. Under different vacuum ranges, there are significant differences in gas flow state, leakage sensitivity, and material outgassing behavior. If the valve level is insufficient, it will become a performance bottleneck for the entire system.

The advanced vacuum applications in China are extensively utilized in the booming chemical industry. The following will showcase common and typical application scenarios
