Preview Questions Maintenance Technician | Role Specific Skill

Question 1: 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 2: How can you ensure proper sealing when installing valves in high-pressure systems in chemical plants?

Which action should you take?

Choose only one option

Ignore sealing requirements and tighten valves as much as possible

Install valves without sealing and rely on pressure to create the seal

Use any available sealant without checking compatibility

Use manufacturer-recommended gaskets, ensure the proper torque specifications are followed, and verify tightness

Question 3: When installing a safety relief valve in a high-pressure system, which compliance action is required?

Which action should you take?

Choose only one option

Skipping the testing of relief valve operation to save time

Using unapproved materials or parts to reduce installation time

Installing the valve quickly without verifying system pressure requirements

Verifying that the valve is properly sized, installed according to specifications, and calibrated

Question 4: How does signal drift affect calibration of sensors in chemical plants, and how should it be addressed?

Which action should you take?

Choose only one option

Drift is acceptable as long as the sensor is within 10% of the reading

Signal drift can be ignored until the sensor is replaced

Signal drift can lead to inaccurate readings, which should be corrected by recalibration

Signal drift is normal and should not be addressed during routine maintenance

Question 5: What is the most likely cause of low flow rate in a chemical filtration system?

Which action should you take?

Choose only one option

Clogging of the filter media or pump wear leading to reduced efficiency

Over-pressurization of the filtration system causing safety shutoffs

Incorrect chemical composition or feed rate

A valve setting too high, restricting the flow rate

Question 6: How should a technician approach the installation of a heat exchanger in a petrochemical plant?

Which action should you take?

Choose only one option

Install the heat exchanger without confirming the orientation or piping requirements

Install the unit quickly without verifying manufacturer's installation guidelines

Ensure correct orientation, secure mounting, and proper pipe connections to avoid leaks

Focus only on the external condition and neglect the internal connections
