An Introduction to Machinery Vibration - reliableplant

An Introduction to Machinery Vibration - reliableplant

The effects of vibration can be severe. Unchecked machine vibration can accelerate rates of wear (i.e. reduce bearing life) and damage equipment. Vibrating machinery can create noise, cause safety problems and lead to degradation in plant working conditions. Vibration can cause machinery to consume excessive power and may damage product quality.

If the machine operates in the same vicinity as another machine, it is important to know the running speed of the adjacent mach ine. Occasionally, vibration from one machine can travel through the foun dation or structure and affect vibration levels on an adjac ent machine. Know if the machine is mounted horizontally or vertically.
