Sample Questions and Answers⁚ Electrical Systems
Question 1⁚ What is the purpose of a circuit breaker?
Answer⁚ A circuit breaker is a safety device designed to protect an electrical circuit from damage caused by overcurrent or short circuits. It automatically interrupts the flow of electricity when an overload or fault is detected‚ preventing fires or equipment damage.
Question 2⁚ How do you measure voltage?
Answer⁚ Voltage is measured using a voltmeter‚ ensuring the meter is properly set to the appropriate voltage range before connecting it across the circuit’s two points. Improper settings can damage the meter or lead to inaccurate readings.
Question 3⁚ Explain the difference between AC and DC electricity.
Answer⁚ AC (alternating current) electricity changes direction periodically‚ while DC (direct current) flows consistently in one direction. AC is commonly used in power grids‚ while DC is used in batteries and some electronic devices. Understanding these differences is critical for working safely with different electrical systems.
Question 4⁚ What safety precautions should be taken when working with electrical systems?
Answer⁚ Always de-energize the circuit before working on it‚ using appropriate lockout/tagout procedures. Use insulated tools and wear personal protective equipment (PPE)‚ including safety glasses and gloves. Never work alone on electrical systems.
Sample Questions and Answers⁚ Mechanical Systems
Question 1⁚ Describe the function of a centrifugal pump.
Answer⁚ A centrifugal pump uses a rotating impeller to increase the pressure of a fluid. The impeller’s rotation forces the fluid outwards‚ increasing its velocity and pressure. This principle is crucial in many industrial applications for moving liquids.
Question 2⁚ What are some common causes of bearing failure?
Answer⁚ Bearing failure can result from various factors‚ including insufficient lubrication‚ excessive load‚ misalignment‚ contamination (dirt‚ debris)‚ and vibration. Regular inspection and preventative maintenance are crucial in preventing bearing failures.
Question 3⁚ Explain the purpose of a pressure relief valve.
Answer⁚ A pressure relief valve is a safety device that automatically releases excess pressure from a system to prevent damage or explosions. It opens when the pressure exceeds a predetermined setpoint‚ relieving the pressure and protecting the system’s integrity.
Question 4⁚ How do you check for leaks in a pneumatic system?
Answer⁚ Leaks in pneumatic systems can be detected using soapy water. Applying soapy water to suspect areas will reveal escaping air as bubbles. Regular inspection and maintenance are essential to identify and repair leaks‚ maintaining system efficiency and safety.
Sample Questions and Answers⁚ Preventative Maintenance
Question 1⁚ What is the purpose of a preventative maintenance (PM) program?
Answer⁚ A PM program aims to prevent equipment failures through scheduled inspections‚ lubrication‚ and minor repairs. This extends equipment lifespan‚ reduces downtime‚ and improves overall operational efficiency‚ minimizing costly repairs and unexpected breakdowns. A well-structured PM program is essential for maintaining a safe and productive work environment.
Question 2⁚ How often should a PM schedule for a specific piece of equipment be reviewed and updated?
Answer⁚ PM schedules should be reviewed and updated at least annually‚ or more frequently if operating conditions change significantly. This ensures the schedule remains relevant and effective. Regular assessment and adaptation are key to the success of a preventative maintenance program.
Question 3⁚ What are some key performance indicators (KPIs) used to measure the effectiveness of a PM program?
Answer⁚ KPIs for a PM program include mean time between failures (MTBF)‚ mean time to repair (MTTR)‚ and overall equipment effectiveness (OEE). Tracking these metrics helps assess the program’s success in preventing equipment failures and reducing downtime. Continuous monitoring allows for improvements and adjustments to the program.
