alipainesäiliö

Alipainesäiliö, often translated as vacuum tank or vacuum vessel, is a container designed to hold a partial vacuum. This means the pressure inside the vessel is significantly lower than the atmospheric pressure outside. Alipainesäiliöt are crucial components in various industrial, scientific, and automotive applications where controlled low-pressure environments are needed.

In industrial processes, vacuum tanks are used for applications such as vacuum degassing, where dissolved gases are removed from liquids, or vacuum drying, where moisture is evaporated at lower temperatures. They can also be part of vacuum forming systems, used to shape plastics, or in vacuum distillation processes. In scientific research, vacuum chambers are essential for experiments requiring a controlled environment free from atmospheric contaminants or for simulating space conditions.

In the automotive industry, alipainesäiliö plays a role in systems like brake boosters. The engine's intake manifold naturally creates a vacuum, and this vacuum is stored in the alipainesäiliö. When the driver applies the brakes, this stored vacuum is used to multiply the force applied to the brake pedal, making braking easier.

The construction of an alipainesäiliö must be robust enough to withstand the pressure difference between the inside and outside. Materials commonly used include steel, stainless steel, or sometimes specialized plastics, depending on the application and the substances being contained. Safety features, such as pressure relief valves, are often incorporated to prevent over-pressurization or catastrophic failure. The ability to maintain a stable vacuum level is a key performance indicator for these vessels.
