In mechanical sealing elements, the sealing plane is perpendicular to the axis of rotation and is formed by the contact between two sliding sealing elements—one stationary and the other moving. These elements are pressed together by a spring force. Successful sealing depends on factors such as temperature, lubrication, the amount of solid particles, the chemical composition of the environment, cooling, vibration, pressure changes, operating range, surface quality, misalignment, and material properties. However, the most critical factor affecting the lifespan of the element is heat, so it is essential to ensure that the thermal resistance exceeds the operating temperature.
Guidelines to Follow Before Installing Sealing Elements:
The installation area or workbench must be clean.
Before starting the installation, check the groove dimensions, radii, and chamfers of the areas where the sealing elements will be placed. Also, ensure the surface quality and cleanliness of these grooves.
Burrs that may remain on the corners of the sealing elements should be carefully removed.
Instead of using grease, select a lubricant that is compatible with the material of the sealing element.
Avoid using assembly tools with sharp or pointed edges.
Heating sealing elements in an uncontrolled manner before installation is highly dangerous, as it may damage the physical, mechanical, or chemical properties of the sealing element.
