Preview Questions Maintenance Technician | Role Specific Skill

Question 1: What is the most effective preventive maintenance action to prevent bearing failure in high-speed rotating equipment?

Which action should you take?

Choose only one option

Focusing on visual inspection without monitoring operating parameters

Regular lubrication, vibration monitoring, and periodic checks for wear and alignment

Only lubricating the bearings when noise or vibration becomes apparent

Checking bearings annually without routine lubrication

Question 2: How should the calibration of a pH meter be handled in a corrosive chemical environment?

Which action should you take?

Choose only one option

Use standard pH buffers regardless of the corrosive environment

Calibration should be performed only during scheduled downtime

Use corrosion-resistant calibration solutions and conduct regular checks to ensure accurate pH readings

Calibration is unnecessary if the pH meter appears to function correctly

Question 3: During the calibration of a flowmeter in a petrochemical plant, what is the most important factor to monitor to ensure accuracy?

Which action should you take?

Choose only one option

Only the power supply to the flowmeter and the system's pressure rating

The wiring and sensor connections without checking the actual flow rate

The external housing of the flowmeter for visible damage

The flow rate during calibration, ensuring it matches the meter's specifications

Question 4: What is the first thing to inspect when a high-speed centrifugal fan in a chemical plant fails to reach the desired flow rate?

Which action should you take?

Choose only one option

Inspect the fan blades for damage or wear and verify proper motor speed

Check the bearings for overheating or lubrication issues

Inspect the fan housing for air leakage or damage

Check the fan's electrical connections and control circuits

Question 5: During preventive maintenance of conveyor systems, what should be the primary focus of inspection?

Which action should you take?

Choose only one option

Adjusting the speed settings without considering wear on the rollers

Checking the motor's efficiency without inspecting the belt

Ensuring proper alignment, tension, and lubrication of the conveyor belt

Tightening all bolts to prevent belt slippage

Question 6: When installing a large centrifugal fan, what is the primary task that must be completed to ensure the fan operates efficiently?

Which action should you take?

Choose only one option

Ensure the fan is level and properly aligned with the ductwork to avoid undue strain on the motor

Check only the fan's external appearance and packaging before installation

Test the fan for noise and vibration before installation

Ensure the fan blades are the correct size and free from any visible damage
