Time based maintenance is a maintenance strategy based on a predetermined schedule.

• It involves performing maintenance tasks at set intervals, regardless of the equipment's condition.

• It is often used for equipment that is not critical to operations.

• Examples include changing air filters every three months or replacing belts every six months.

• It can be less effective than condition-based maintenance, which takes into account the actual condition of the equipment.

• However, it can b...read more

Autonomous maintenance is a maintenance approach where operators take responsibility for routine maintenance tasks.

• Operators are trained to perform routine maintenance tasks

• Operators conduct inspections and minor repairs

• Autonomous maintenance reduces downtime and improves equipment reliability

• Operators become more familiar with equipment and can identify potential issues

• Autonomous maintenance is a key component of Total Productive Maintenance (TPM)

NPSH stands for Net Positive Suction Head and is a measure of the pressure available at the suction port of a pump to prevent cavitation.

• NPSH is important for ensuring that a pump does not cavitate, which can cause damage to the pump and reduce its efficiency.

• It is calculated by subtracting the vapor pressure of the liquid being pumped from the total suction head of the pump.

• NPSH is typically provided by the pump manufacturer and must be considered when designing a pumping sy...read more

Total productive maintenance is a maintenance strategy that aims to maximize equipment effectiveness and minimize downtime.

• TPM involves regular maintenance and inspection of equipment to prevent breakdowns

• It emphasizes employee involvement and training to improve equipment performance

• TPM also includes continuous improvement efforts to optimize equipment and processes

• Examples of TPM techniques include autonomous maintenance, planned maintenance, and quality maintenance

Breakdowns are handled by identifying the root cause, prioritizing repairs, and implementing preventive measures.

• Conduct a thorough investigation to determine the cause of the breakdown

• Prioritize repairs based on the impact on production and safety

• Implement preventive measures to avoid future breakdowns

• Maintain a record of breakdowns and repairs for analysis and improvement

• Train and educate staff on proper maintenance and troubleshooting techniques

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

• It involves monitoring equipment performance and collecting data

• Data is analyzed to identify patterns and predict when maintenance is needed

• This helps to prevent equipment failure and reduce downtime

• Examples include using sensors to monitor machine vibrations or oil analysis to detect wear in engines

Pump flow rate can be calculated by multiplying the pump's displacement per revolution by the pump's speed.

• Calculate the pump's displacement per revolution (in cubic inches or cubic centimeters)

• Determine the pump's speed (in revolutions per minute)

• Multiply the displacement per revolution by the speed to get the flow rate (in cubic inches or cubic centimeters per minute)

Dry gas seals are used in centrifugal compressors to prevent gas leakage and contamination.

• Prevents gas leakage in centrifugal compressors

• Helps in preventing contamination of process gas

• Used in high-pressure applications

• Requires a barrier gas to operate effectively
