P J B Engineers Interview Questions and Answers

Various tools used for troubleshooting of a pump include pressure gauges, flow meters, vibration analyzers, and infrared thermometers.

• Pressure gauges to measure the pressure of the fluid being pumped

• Flow meters to measure the flow rate of the fluid

• Vibration analyzers to detect any abnormal vibrations in the pump

• Infrared thermometers to measure the temperature of the pump and its components

• Visual inspection tools such as borescopes and endoscopes to inspect the internal compon...read more

The allowable noise and vibration limit for a fan depends on various factors such as the type of fan, its location, and the surrounding environment.

• The allowable noise and vibration limit for a fan is typically specified by the manufacturer in the fan's technical specifications.

• The limit may also be regulated by local or national noise ordinances and regulations.

• Factors such as the type of fan, its location, and the surrounding environment can affect the allowable noise and v...read more

RVA can be done through Fishbone method by identifying the possible causes of the problem and categorizing them into branches.

• Identify the problem and write it at the head of the fishbone diagram

• Identify the major categories of possible causes and draw branches for each category

• Identify the subcategories of each branch and draw smaller branches for each subcategory

• Brainstorm and list all possible causes under each subcategory

• Analyze the causes and identify the root cause of t...read more

Predictive maintenance is a technique that uses data analysis to predict when equipment maintenance is needed.

• Predictive maintenance uses sensors and data analysis to monitor equipment performance.

• It can detect potential issues before they become major problems.

• This technique can help reduce downtime and maintenance costs.

• Examples include monitoring vibration levels in rotating equipment or analyzing oil samples for signs of wear.

Water balance diagram is a schematic representation of water flow and usage in a system.

• It shows the sources of water, its distribution, and the amount of water used in different processes.

• It helps in identifying areas of water loss and optimizing water usage.

• It is commonly used in industries such as power plants, chemical plants, and water treatment plants.

• Example: A water balance diagram for a power plant would show the sources of water (such as a river or lake), the amount...read more

Implement quality control measures at every stage of production process to ensure product quality.

• Establish quality standards and procedures for each product

• Regularly inspect and test products during production

• Train production staff on quality control measures

• Implement corrective actions for any quality issues identified

• Utilize quality control tools such as Six Sigma or Total Quality Management

• Collaborate with suppliers to ensure quality of raw materials

Types of control in safety include administrative controls, engineering controls, and personal protective equipment.

• Administrative controls involve policies, procedures, and training to reduce risk (e.g. safety training, work permits)

• Engineering controls use physical means to isolate people from hazards (e.g. machine guards, ventilation systems)

• Personal protective equipment (PPE) includes items like gloves, helmets, and goggles to protect workers from hazards

Glass can contribute to net zero building through energy efficiency and renewable energy generation.

• High-performance glass can reduce energy consumption by allowing natural light while minimizing heat gain or loss.

• Solar panels can be integrated into glass facades to generate renewable energy.

• Glass can also be used for insulation and shading to further improve energy efficiency.

• Recycled glass can be used in building materials to reduce waste and carbon emissions.

• Smart glass te...read more
