Ε Semester engineers

An engineer on board can ……………………… something erratic in equipment by feeling the heat, or by listening to the noise, or by watching the device’s status. It may ……………………………… from person to person. Vibration analysis, where needed, can be ……………… by maintenance engineers who work in specialist companies and use reliable methods that ……………….. written data. Amplitude and frequency are measurable parameters used by vibration analysis to describe the vibration. Amplitude describes the amount of vibration ……………….. on the object. More movement means more criticality of the object condition. Velocity is ……………………. in a specific direction and how fast the object movements …………………… at any given time is ………………….. in graphical waveform. Vibration analysts measure velocity data for a specified time period and ………………………… analysis accordingly. Rotating machines ……………….. to vibrate, so vibration analysis on a regular basis is needed to ……………………. the operational health of equipment. Machine failures can be drastically ……………….. by adopting a “Preventive Maintenance Tool” program, which is also known as a “Condition Based Maintenance System.” The aim of Vibration Analysis is to ……………….. the deteriorating condition of equipment before it leads to a breakdown. Whenever machine vibration ……………………. normal limits, it ………………… some problem in the mechanism, which could involve alignment, wear and tear, or loosening of parts. To ………………………. this, corrective action should be ……………………. based on the data collected from the machine. Critical machines should be ……………….. by installing permanent type vibration meter on the required part. This should give signs of wear and tear to be ………………….. well in advance before the fault ………………. into an expensive problem.
