P-Mech Consultant Engineer Interview Questions and Answers

Starting and stopping a boiler feed pump requires careful procedures to ensure safety and efficiency.

• Check the pump and system for any leaks or damage before starting.

• Ensure that the boiler is at the correct pressure and temperature.

• Open the isolation valves to allow water flow to the pump.

• Start the pump using the control panel, monitoring for unusual noises.

• Once the pump is running, check the pressure gauges to ensure...read more

Common vacuum pump failures include mechanical wear, seal leaks, and motor issues, often leading to performance loss.

• Mechanical wear: Bearings and rotors can wear out over time, causing reduced efficiency.

• Seal leaks: Damaged or worn seals can lead to loss of vacuum, impacting system performance.

• Motor issues: Electrical failures or overheating can prevent the pump from operating correctly.

• Contamination: Particles or flu...read more

Safe operation of a CEP involves careful start/stop procedures and understanding cavitation causes and prevention.

• Start the CEP gradually to avoid sudden pressure changes.

• Monitor system parameters like flow rate and pressure during startup.

• Stop the CEP by gradually reducing the load to prevent water hammer.

• Cavitation can occur due to low inlet pressure or high fluid velocity.

• To avoid cavitation, ensure adequate NPSH (N...read more

In case of a blackout, immediate actions include assessing the situation, ensuring safety, and restoring power efficiently.

• Assess the situation: Check if the blackout is localized or widespread.

• Ensure safety: Activate emergency lighting and guide personnel to safe areas.

• Notify relevant personnel: Inform management and maintenance teams about the blackout.

• Check backup systems: Verify if backup generators are operational...read more
