Bnk Power Solution Interview Questions and Answers

Cooling tower performance can be measured by monitoring key parameters such as temperature differentials, flow rates, water quality, and energy consumption.

• Monitor temperature differentials between the inlet and outlet water to ensure efficient heat transfer.

• Measure flow rates to ensure proper water circulation and cooling capacity.

• Regularly test water quality for factors such as pH, conductivity, and microbial growth to prevent fouling and corrosion.

• Track energy consumption ...read more

Preventive maintenance is planned maintenance to prevent breakdowns, while breakdown maintenance is reactive maintenance after a breakdown occurs.

• Preventive maintenance is scheduled in advance to prevent equipment failure.

• Breakdown maintenance is performed after a breakdown has already occurred.

• Preventive maintenance helps in reducing unexpected downtime and prolonging equipment life.

• Breakdown maintenance can be costly and lead to production delays.

• Examples of preventive main...read more

Boiler is a closed vessel where water is heated to generate steam. Safety measures include regular maintenance, pressure relief valves, and water level controls.

• Boilers heat water to generate steam for heating or power generation

• Safety measures include regular maintenance to prevent leaks or malfunctions

• Pressure relief valves release excess pressure to prevent explosions

• Water level controls ensure proper water levels to prevent overheating

A pump is a mechanical device used to move fluids by applying mechanical force.

• Pumps are used in various industries such as oil and gas, water treatment, and manufacturing.

• They can be classified into different types based on their working principles, such as centrifugal pumps and positive displacement pumps.

• Pumps are used to increase the pressure or flow rate of fluids, enabling them to be transported over long distances.

• They can be powered by electricity, engines, or even ma...read more

Pump operation refers to the process of using a pump to transfer fluids from one place to another.

• Pump operation involves the conversion of mechanical energy into hydraulic energy.

• Pumps are used in various industries such as water supply, oil and gas, chemical processing, and HVAC systems.

• The operation of a pump typically involves the intake of fluid through an inlet, the creation of pressure to move the fluid, and the discharge of the fluid through an outlet.

• Different types ...read more

Safety interlocks of a chiller ensure safe operation by monitoring various parameters and shutting down the system in case of any abnormalities.

• Safety interlocks monitor parameters such as temperature, pressure, and flow rate to ensure safe operation.

• If any parameter exceeds safe limits, the interlock system will shut down the chiller to prevent damage or accidents.

• Examples of safety interlocks include high-pressure cut-off switches, low-temperature alarms, and flow rate sens...read more
