Junior Officer Engineering Interview Questions and Answers

The necessary checking procedure of a glass lined reactor involves visual inspection, pressure testing, and checking for any signs of corrosion or damage.

• Perform a visual inspection of the glass lining to check for any cracks, chips, or signs of wear.

• Conduct a pressure test to ensure the reactor can withstand the required operating pressure.

• Check for any signs of corrosion on the glass lining, especially in areas exposed to corrosive substances.

• Inspect the reactor's accessori...read more

Steam traps are devices used to discharge condensate and non-condensable gases from steam systems.

• There are three main types of steam traps: mechanical, thermostatic, and thermodynamic.

• Mechanical steam traps use a float to open and close a valve.

• Thermostatic steam traps use a temperature-sensitive element to open and close a valve.

• Thermodynamic steam traps use the difference in pressure between steam and condensate to operate a valve.

• Steam traps prevent steam from escaping an...read more

Flush bottom valves are used to drain liquids from tanks. Troubleshooting involves identifying and fixing issues with the valve.

• Check for leaks or blockages in the valve

• Inspect the valve for damage or wear and tear

• Ensure that the valve is properly installed and tightened

• Verify that the valve is compatible with the liquid being drained

• Consult manufacturer's instructions or seek expert advice if necessary

There are two types of vacuum systems: liquid ring and dry vacuum systems.

• Liquid ring vacuum systems use a liquid as a sealant to create a vacuum.

• Dry vacuum systems use oil-free pumps to create a vacuum.

• Examples of liquid ring vacuum systems include steam jet ejectors and water ring vacuum pumps.

• Examples of dry vacuum systems include scroll pumps and turbo molecular pumps.
