We are currently setting goals for improving Mean Time Between Repairs (MTBR) on electric motors (5 HP and above) and screw conveyors. While benchmarking for centrifugal pumps is widely available, information on motors and screws is scarce. Our current MTBR stands at 59.5 months for motors and 7.1 months for screws. If you are aware of any benchmarking standards for these components, please get in touch. Feel free to email me with any insights you may have.
Jim, I will need to consult my CEMA guide to get more information on benchmarking. However, there are likely solutions available to enhance the longevity of your screws. Please provide me with the specifics of your application so I can offer suggestions on how to improve their lifespan. Best regards,
Have you had the opportunity to explore HP Bloch's comprehensive 4-volume book series? One volume specifically highlights a variety of equipment with detailed MTBF values.
I haven't checked it out yet, but I'll do some research to see what it offers. Thanks for the tip, Josh!
I've faced a similar issue with getting benchmarks for electric motors and screw conveyors. From my experience, substantial improvement in MTBR can be achieved by employing predictive maintenance strategies instead of reactive ones. Tools like vibration analysis, infrared thermography, and motor current analysis can help identify early signs of failure, thus prolonging the MTBR intervals. However, every machinery system is unique and might need different strategies. Specific benchmarks might not be available due to variations in different operational environments and variables. It is best to set customized goals based on historical performance and continual improvement.
While I don't have specific benchmarking standards for motors and screws, I'd like to suggest that you might focus on preventive and predictive maintenance practices to enhance the MTBR. Regularly monitoring the operating conditions, vibration levels, and temperature of your motors and conveyors can give you insights into potential issues before they cause system outages, thereby increasing MTBR. I'd also recommend researching organizations like the Electric Power Research Institute (EPRI) or the Electrical Apparatus Service Association (EASA) who might have some relevant resources.

Answer: Answer: Benchmarking helps organizations understand where they stand in terms of MTBR compared to industry standards, identify areas for improvement, and set realistic goals to enhance the reliability and performance of electric motors and screw conveyors.
Answer: Answer: The current MTBR stands at 59.5 months for electric motors (5 HP and above) and 7.1 months for screw conveyors. These figures serve as the baseline for measuring future improvements in maintenance and reliability.
Answer: Answer: The scarcity of benchmarking standards for electric motors and screw conveyors may be due to the specific nature of these components, variations in application requirements, and industry focus on other equipment like centrifugal pumps. Efforts are being made to gather relevant data and establish benchmarking standards for motors and screws.
