Preview Questions Maintenance Technician | Role Specific Skill

Question 1: When scheduling preventive maintenance for compressors, what is the main focus during routine checks?

Which action should you take?

Choose only one option

Checking the system's energy consumption without checking for mechanical issues

Cleaning the compressor's exterior without examining internal components

Replacing all filters and changing the oil without inspecting for leaks

Monitoring vibration, temperature, and pressure to detect abnormal performance

Question 2: What is the first action to take when installing an industrial refrigeration system in a chemical plant?

Which action should you take?

Choose only one option

Ensure the system is evacuated and fully charged with refrigerant according to the manufacturer's specifications

Begin the electrical connection without verifying the refrigerant system

Install the cooling units without considering the refrigerant type

Simply connect the refrigerant lines and start the system without checking system integrity

Question 3: During machinery installation in a chemical plant, what should be the first step in ensuring proper alignment of rotating equipment?

Which action should you take?

Choose only one option

Visually inspect alignment without using measuring instruments

Use only feeler gauges to measure gaps and distances between components

Use precision alignment tools, such as dial indicators or laser alignment systems, to check shaft alignment

Adjust the motor's position until it appears visually aligned

Question 4: What is the impact of improper calibration of level sensors in chemical storage tanks?

Which action should you take?

Choose only one option

It improves the efficiency of tank filling and emptying operations

There is minimal impact, as level sensors are typically redundant

It can lead to inaccurate level readings, resulting in overflows, underfills, or unsafe conditions

It only affects the safety alarms, not the operational efficiency

Question 5: When installing a centrifugal pump, what is the most critical factor to ensure proper operation?

Which action should you take?

Choose only one option

Lubricating the pump bearings only after installation

Proper alignment of the pump shaft with the motor and accurate placement of foundation bolts

Ensuring that the pump is as close as possible to the motor to reduce pipe length

Focusing on the visual condition of the pump before installation

Question 6: What is the significance of performing a vibration analysis when troubleshooting rotating equipment?

Which action should you take?

Choose only one option

Vibration analysis helps identify issues such as unbalance, misalignment, and bearing wear before failure

Vibration analysis provides irrelevant data and should be ignored

Vibration analysis is only useful for non-rotating systems

Vibration analysis is unnecessary and does not contribute to equipment diagnosis
