What are the components of an airlock?

Published in Airlock Components 2 mins read

An airlock's components depend on the specific type of airlock, but a rotary airlock, for example, consists of several key parts. These parts work together to create a seal and prevent air from flowing freely between two areas with different pressure or environments.

Components of a Rotary Airlock

A rotary airlock typically comprises the following elements, as detailed in the reference:

  • Outer Metal Housing: This forms the external structure and provides a rigid enclosure for all other components.

  • Multi-Vane Rotor and Shaft: The rotor is the rotating component with multiple vanes or pockets. It moves to transfer material from one side of the airlock to the other, while maintaining an airtight seal. The shaft is what the rotor is attached to and enables it to turn.

  • Endplates: These plates seal the ends of the housing, preventing leaks and ensuring the airlock's integrity.

  • Drive: The drive is the mechanism that rotates the rotor, typically a motor with gearing.

  • Shaft Packing Seals: These seals are critical for maintaining the airlock's pressure differential by preventing air leakage around the rotating shaft.

  • Bearings: These components facilitate the smooth rotation of the shaft and rotor, reducing friction and wear.

Table Summarizing Airlock Components

Component Function
Outer Metal Housing Encloses and provides the structural framework for the airlock.
Multi-Vane Rotor & Shaft Transports material while maintaining an airtight seal through rotation.
Endplates Seal the ends of the housing to prevent leaks.
Drive Rotates the rotor.
Shaft Packing Seals Prevent air leakage around the rotating shaft.
Bearings Support smooth rotation of the shaft.

These components ensure that the airlock performs its function effectively and safely, be it to transfer solid material while maintaining a pressure differential, or to prevent rapid air transfer between two areas.
