1. Breakdown maintenance

2. Proactive maintenance

3. Predictive maintenance

4. Preventive maintenance.

1.5 Name the three categories under which plant equipment can be classified.

6.

1.6 In a typical process plant, there are five cooling water supply pumps. Depending on the weather conditions, four of the five pumps are operational at any point in time. Electrical motors with a rating of 1.5 MW drive these pumps. Under which category would you classify these pumps?

7.

1.7 Predictive maintenance principles are analogous to:

1. Crime detection

2. Medical science

3. Forensic medicine

4. Failure analysis of electronic components.

8.

1.8 One of the following is not a predictive maintenance technique:

1. Root cause failure analysis

2. Ultrasonic thickness measurement

3. Performance evaluation

4. Vibration analysis.

9.

1.9 Vibration analysis (in the detection mode) is done:

1. On a regular basis for selected machines

2. To detect the severity of fault in a machine

3. To ascertain the time after which machine or its component will fail

4. To detect faults in vibration measuring...
