Three Techniques for a Positive Seal in Vane Air Motors

What are three techniques used to assure a positive seal between the tips of the vanes and the walls of the internal chamber of a vane air motor?

a) Using lubricants, thermal expansion, O-ring seals
b) Welding, soldering, adhesives
c) Friction reduction, vacuum sealing, magnetic sealing
d) None of the above

Answer:

Three techniques used to assure a positive seal in a vane air motor are lubrication, thermal expansion, and O-ring seals.

Therefore, the correct answer is: option a) Using lubricants, thermal expansion, O-ring seals

Explanation:

Three techniques used to assure a positive seal between the tips of the vanes and the walls of the internal chamber of a vane air motor are:

  1. Using lubricants: Lubricants can be applied to the tips of the vanes and the walls of the chamber to reduce friction and create a better seal.
  2. Thermal expansion: Heating the components can cause them to expand slightly, allowing for a tighter seal between the vanes and the walls of the chamber.
  3. O-ring seals: O-rings made of rubber or other flexible materials can be used to create a seal between the vanes and the walls of the chamber. The O-ring is compressed when the vanes are in contact with the walls, creating a positive seal.
