Fill in the correct form of the word in capital letters
An engineer on board can identify something ERROR
in equipment by feeling the heat. More movement means more CRITICAL
of the object condition. Vibration analysts measure velocity data for a specified time period and carry out analysis ACCORDING
. Machine failures can be drastically reduced by adopting a PREVENT
Maintenance Tool program. Whenever machine vibration crosses normal limits it indicates some problem in the mechanism, which could involve ALIGN
, wear and tear or LOOSE
of parts. To overcome this CORRECT
actions should be undertaken based on collected data from the machine. When vibrations occur in big sized machines, operating under heavy loads, the INTENSE
of vibration magnifies because of large mass rotation and COMBUSTION
gases forced inside the machinery. If the vibration levels increase beyond the minimal level, it may lead to DEFORM
or BREAK
of engine components. There are two basic criteria for determining ACCEPT
in the level of vibrations. TORSION
Dampers address twisting vibrations from EVEN
torque pulses. Dampers absorb vibration energy to reduce OSCILLATE
frequency. BALANCE
in rotating components is one of the common reasons for engine vibrations. HARMONY
resonance is one of the reasons for engine vibration. Silicon is a VISCOSITY
fluid. The FOUL
of the propeller is one of the reasons for engine vibration. AXIS
dampers help reduce vibration.
