Preview Questions Maintenance Technician | Role Specific Skill

Question 1: In troubleshooting gas compressors, what is the most likely cause of low output pressure?

Which action should you take?

Choose only one option

Over-tightened valve seals restricting the flow of gas

A restriction or blockage in the intake or discharge line

Excessive cooling leading to high pressure in the system

Incorrect temperature settings causing the compressor to fail

Question 2: What is the first step in troubleshooting a pump failure in a chemical plant?

Which action should you take?

Choose only one option

Replace the pump immediately with a new one

Disassemble the pump and inspect for visible damage

Continue operation and monitor the pump's performance

Check the power supply and control signals to ensure the pump is receiving adequate input

Question 3: When performing preventive maintenance on centrifugal pumps, what is the first task to check in the maintenance procedure?

Which action should you take?

Choose only one option

Verify alignment and condition of the shaft and bearings to avoid misalignment and excess wear

Change the pump seals to prevent leaks during normal operation

Ensure the fluid is clean and there are no contaminants in the pump system

Check the pump's impeller for cleaning and general condition

Question 4: What is the best method for testing the accuracy of a temperature sensor in a chemical reactor?

Which action should you take?

Choose only one option

Use a high-precision reference thermometer and compare readings at various points within the operational temperature range

Use only the manufacturer's calibration data without testing the sensor's real-time performance

Check the sensor only when it displays an error or malfunction

Use any available thermometer and check the sensor once

Question 5: When performing preventive maintenance on a cooling tower, what is the most crucial part to inspect?

Which action should you take?

Choose only one option

The electrical wiring and control panels only

The condition of the fan blades, water distribution system, and the fill media

The overall aesthetics of the cooling tower

The visual cleanliness of the external structure

Question 6: In the case of overheating in a motor driving a compressor, which of the following is the first area to investigate?

Which action should you take?

Choose only one option

Inspect the compressor internals for wear or misalignment

Check for electrical imbalances or phase loss in the motor

Verify the cooling system for blockages or inadequate airflow

Check the alignment of the motor and drive components
