Vibration Test and Shock Absorption of Coal Crusher Chambers in Thermal Power Plants (I)‎: Field Test and Assessment

Abstract EN

A field vibration test was conducted on the coal crusher chamber of a thermal power plant to evaluate its vibration performance.

The vibration displacements and velocities of the structure, coal crusher body, and vibration-isolation platform were tested.

The vibration safety of the coal crusher chamber and the vibration-isolation efficiency of the spring vibration-isolation system were evaluated based on the test results, and the reason the vibration exceeded the limit was analyzed.

This study showed that the vibration displacement of a coal crusher with a spring vibration-isolation system met the code requirements, but the equipment had greater vibration displacements, which were related to the connection between the equipment and the platform.

Compared to a steel platform, the vibration displacement of a concrete platform was smaller, and the vibration-isolation efficiency was greater.

The vibration displacements of the coal crusher body could be reduced by controlling the vibration displacements of the platform.
