Condition Monitoring Engineer Interview Questions and Answers

A set of questions related to vibration analysis and condition monitoring.

• Vibration is the oscillation of an object around a reference point.

• FFT (Fast Fourier Transform) is a mathematical algorithm used to analyze vibration signals.

• Time waveform is a graph of vibration amplitude over time.

• Cost down testing is a process of reducing the cost of maintenance and repair.

• Resonance is a phenomenon where an object vibrates at its natural frequency.

• Natural frequency is the frequency a...read more

Regular maintenance, monitoring and timely repairs can improve machine efficiency.

• Regularly inspect and maintain the machine

• Monitor machine performance using condition monitoring techniques

• Identify and address any issues or defects promptly

• Implement predictive maintenance strategies

• Train operators and maintenance staff on proper use and maintenance of the machine

Bump test verifies the proper functioning of gas detectors. MCSA detects faults in motors. Laser alignment ensures accurate alignment of rotating machinery.

• Bump test involves exposing the gas detector to a known concentration of gas to ensure it triggers an alarm

• MCSA uses vibration analysis to detect faults in motors such as unbalance, misalignment, and bearing defects

• Laser alignment involves using a laser to align the shafts of rotating machinery to ensure they are parallel ...read more

Types of cement include Portland cement, white cement, rapid hardening cement, and low heat cement.

• Portland cement is the most common type and is used in general construction.

• White cement is used for architectural purposes and to create colored concrete.

• Rapid hardening cement sets quickly and is used in projects with tight deadlines.

• Low heat cement generates less heat during hydration and is used in large concrete structures.

TG alignment is done by measuring and adjusting the position of the turbine generator components.

• Measure the position of the turbine and generator components using laser alignment tools

• Adjust the position of the components by shimming or moving the baseplate

• Repeat the measurement and adjustment process until the alignment is within specified tolerances

• Perform a final check to ensure the alignment is correct
