Jayaswal Neco Industries Interview Questions, Process, and Tips

Preventive maintenance is scheduled maintenance to prevent breakdowns while predictive maintenance uses data to predict failures.

• Preventive maintenance involves regularly scheduled maintenance to prevent equipment breakdowns and prolong the lifespan of equipment.

• Predictive maintenance uses data analysis to predict when equipment failure is likely to occur, allowing for maintenance to be scheduled before a breakdown occ...read more

PLC stands for Programmable Logic Controller and HMI stands for Human Machine Interface.

• PLC is a digital computer used for automation of electromechanical processes.

• It is used to control machinery on factory assembly lines, amusement rides, or light fixtures.

• HMI is a graphical interface that allows humans to interact with machines.

• It provides a visual representation of the process being controlled by the PLC.

• Examples o...read more

Power factor can be managed by using capacitors, improving equipment efficiency, and reducing reactive power.

• Install capacitors to offset reactive power and improve power factor

• Upgrade equipment to more efficient models

• Reduce the amount of reactive power by optimizing operations

• Implement power factor correction techniques

• Regularly monitor and maintain power factor levels

Quality issues in alloy steel and customer complaints can be resolved through proper testing and inspection.

• Quality issues in alloy steel can arise due to improper composition, heat treatment, or manufacturing processes.

• To address customer complaints, it is important to conduct thorough testing and inspection of the steel to identify the root cause of the issue.

• Solutions may include adjusting the manufacturing process,...read more

The specific water consumption rate in steel industries varies depending on various factors such as the production process, technology used, and water management practices.

• Specific water consumption rate in steel industries is measured in terms of water used per ton of steel produced.

• It can range from 2 to 50 cubic meters per ton of steel, depending on the efficiency of the steelmaking process.

• Factors influencing the s...read more

Centrifugal pumps work on the principle of converting rotational energy into kinetic energy to move fluid.

• Centrifugal pumps use an impeller to create centrifugal force, which pushes the fluid towards the outlet.

• The impeller rotates at high speed, creating a low-pressure zone at the center and a high-pressure zone at the outer edges.

• Fluid enters the pump through the suction inlet and is accelerated by the impeller, incr...read more

A heat exchanger is a device used to transfer heat between two or more fluids.

• Heat exchangers are commonly used in HVAC systems, power plants, and refrigeration systems.

• They work by allowing heat to transfer from one fluid to another without the fluids mixing.

• There are different types of heat exchangers, including shell and tube, plate, and finned tube heat exchangers.

• Heat exchangers can be used for heating, cooling, o...read more
