STL Training Shift Incharge Interview Questions, Process, and Tips

Chiller troubleshooting involves identifying and resolving issues with the chiller system to ensure proper functioning.

• Check for power supply to the chiller unit

• Inspect for any leaks in the system

• Monitor the temperature and pressure readings

• Clean or replace filters regularly

• Verify proper refrigerant levels

• Look for any unusual noises or vibrations

Air compressor capacity calculation involves determining the required flow rate and pressure for the application.

• Calculate the required flow rate in cubic feet per minute (CFM) based on the air tools or equipment being used.

• Determine the required pressure in pounds per square inch (PSI) for the application.

• Use the formula: CFM = (Tool SCFM x Number of Tools) + (Leakage SCFM) + (Pressure Drop SCFM)

• Consider factors such ...read more

Pump flow and piping design are crucial for efficient operation and performance in industrial settings.

• Consider the required flow rate and pressure for the system

• Select a pump that can meet the flow and pressure requirements

• Design the piping layout to minimize friction losses and optimize flow

• Ensure proper sizing of pipes and fittings to prevent restrictions

• Consider factors like material compatibility, temperature, and

Cooling towers are heat removal devices used to transfer process waste heat to the atmosphere.

• Cooling towers work by evaporating a small portion of the water to remove heat from the rest of the water.

• Hot water from the process is pumped to the top of the cooling tower and distributed over the fill material.

• As the water flows over the fill material, it is exposed to air, which causes some of it to evaporate and cool dow...read more
