CBM Engineer Interview Questions and Answers

Bearings are used to reduce friction between two moving parts. There are several types of bearings available.

• Ball bearings

• Roller bearings

• Needle bearings

• Thrust bearings

• Sleeve bearings

• Tapered roller bearings

• Cylindrical roller bearings

• Angular contact bearings

• Self-aligning ball bearings

Different types of maintenance practices include preventive, corrective, predictive, and condition-based maintenance.

• Preventive maintenance involves regularly scheduled inspections and maintenance to prevent breakdowns.

• Corrective maintenance is performed after a failure has occurred to restore equipment to its normal operating condition.

• Predictive maintenance uses data analysis to predict when maintenance is needed based on equipment performance.

• Condition-based maintenance in...read more

Condition monitoring is the process of monitoring the health of a machine or system to detect any potential issues before they become major problems.

• It involves collecting data on various parameters such as temperature, vibration, and noise levels.

• This data is then analyzed to identify any anomalies or patterns that may indicate a problem.

• Condition monitoring can help prevent unplanned downtime, reduce maintenance costs, and extend the life of equipment.

• Examples of condition ...read more

Vibration is the rapid back-and-forth movement of an object or medium.

• Vibration can be caused by mechanical or electrical sources.

• It can be felt or heard, and can have both positive and negative effects.

• Examples include earthquakes, musical instruments, and machinery.

• Vibration analysis is used to diagnose and prevent mechanical failures.

Different parts of a pump include impeller, casing, shaft, bearings, seals, and motor.

• Impeller - rotates and creates flow

• Casing - contains the impeller and directs flow

• Shaft - connects the impeller to the motor

• Bearings - support the shaft and reduce friction

• Seals - prevent leakage

• Motor - provides power to the impeller
