A boat's bellows are flexible gaskets that protect the engine from water. This product entails ships dumping the heat generated by the machine outside to keep the engine cool. It works great as a cooling system, but it leaves some components of your boat vulnerable to the damage that water can cause.
The primary function of a bellows is to contain air and expel it at a specific pressure and direction to achieve various goals. Whether the container is deformable or not, the air kept inside is released through a nozzle or outlet conduit to attain multiple goals when compressed and reduced in volume.
Bellows have separate air inlets and outlets. This process means they have non-return valves or check valves to ensure that air enters and exits in the same direction.
Functions:
- Connectors: The bellows used as connectors serve several functions in turn, including containing substances that pass through the fixing points that they connect, absorbing thermal expansion or contraction, vibration, and system misalignment that may exist in the machine.
- Seals: Bellows used as seals are critical for protecting reciprocating mechanisms and preventing them from becoming contaminated by the environment.
