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:
- 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.
- 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.
- 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.
