Encotec Energy Interview Questions and Answers

Cavitation is the formation and collapse of vapor bubbles in a liquid due to pressure changes.

• Occurs when pressure drops below the vapor pressure of the liquid

• Can cause damage to pumps and other equipment

• Can be reduced by increasing pressure or changing the fluid properties

• Examples include propeller cavitation on boats and erosion in hydraulic systems

Balancing disc in boiler feed pump helps to reduce axial thrust and maintain stability.

• Balancing disc is a rotating disc placed between the impeller and the shaft.

• It helps to balance the hydraulic forces acting on the impeller.

• Reduces axial thrust and maintains stability of the pump.

• Improves the life of bearings and other components.

• Example: KSB boiler feed pump has a balancing disc for stable operation.

Types of pumps and their maintenance procedures

• Centrifugal pumps require regular inspection of impeller and bearings

• Reciprocating pumps need piston and valve maintenance

• Diaphragm pumps should have diaphragm replacements as needed

• Gear pumps may require gear and seal replacements

• Regularly check for leaks, vibrations, and unusual noises in all pump types

Valves are mechanical devices used to control the flow of fluids in a system. They require regular maintenance to ensure proper functioning.

• Types of valves include ball valves, gate valves, globe valves, and butterfly valves.

• Maintenance tasks for valves may include lubrication, cleaning, and replacing worn parts.

• Regular inspection of valves is important to detect leaks or other issues early on.

• Valve maintenance schedul...read more
