Question: 1 / 400

Why is thermal growth an important aspect in machine alignment?

It reduces the wear of components

It affects the clearance of the machinery

It impacts positioning during changes in temperature

Thermal growth is critical in machine alignment because it impacts the positioning of machinery during changes in temperature. As machinery operates, it generates heat, causing components to expand. If alignment is not adjusted for this thermal growth, misalignment can occur when components expand differently due to varying operating temperatures. This misalignment can lead to increased wear, vibration, and inefficiencies, ultimately affecting the performance and reliability of the equipment. Therefore, proper consideration of thermal growth is essential for maintaining precise alignment, which is necessary for optimal operation and longevity of machines.
