Characteristics of ultra-high vacuum

01 High cleanliness High cleanliness is the fundamental reason why surface analysis requires ultra-high vacuum. Surface physics often studies the physical phenomena of several atomic layers on the surface. Therefore, even under vacuum conditions, the...

Detailed interpretation of water ring vacuum pump-

Detailed interpretation of water ring vacuum pump

water ring vacuum pump is the most common type of liquid ring vacuum pump. The liquid ring vacuum pump is a rotor core with multiple blades installed in the pump shell. When it rotates, it throws the liquid to the pump shell and forms a liquid ring concentric with the pump shell. The liquid ring and the rotor blade form a rotating varus vacuum pump with periodic volume changes. When the working liquid is water, it is called water ring vacuum pump.

Knowledge of vacuum rubber seal

Since the birth of the first O-ring in the mid-19th century, rubber seals have been widely used due to their advantages of simple structure, convenient loading and unloading, reliable sealing, small dynamic friction resistance and no need for periodic adjustment. Rubbers commonly used in vacuum systems include natural latex vulcanized rubber, synthetic rubber (such as butyl, chlorine, nitrile rubber) and silicone rubber, fluorine rubber, etc.

Science: understand vacuum

There are many scenes involving vacuum in life, such as vacuum packaging, vacuum thermos cup and so on. In industry, as long as the environment below a standard atmospheric pressure can be called "vacuum", but according to the different pressure they can be divided into low vacuum, high vacuum, ultra-high vacuum and other different degrees of vacuum.
