As we transition to a 24/7 production schedule in our large manufacturing facility, we are seeking advice on enhancing our preventive maintenance program. With a team of PdM techs, Area Lube techs, and an on-site oil analysis lab, we have been primarily relying on 360* walk-around PM inspections. However, we recognize the need for more hands-on, thorough inspections to ensure optimal equipment performance. Given our minimal machine downtime and lack of redundant processes, we are facing challenges in implementing a more effective PM approach. We welcome insights and success stories from others who have overcome similar obstacles. Thank you in advance for your input.
If you have a history of identifying failing components during maintenance inspections that could have led to catastrophic events, these inspections can be considered value-added. Do you have historical data that specifies the failures found, when they were discovered, and the impact of preventing potential catastrophic events? This data will support the importance of conducting these critical inspections, even if they require production outages. Reviewing your maintenance strategies using reliability and risk-based engineering methods may be necessary based on your historical data. If your history justifies shutting down production for critical inspections, management may support reallocating resources for further analysis of maintenance strategies. Implementing strategies like RCM, spare parts management, and equipment redesign can improve maintenance efficiency and prevent potential failures. Consider the impact of balancing equipment maintenance needs and production schedules, especially in a 24/7 operation where nighttime maintenance can be more costly. Scheduling planned outages during regular work hours when possible can help optimize resources and minimize costs. This approach may differ for facilities with shorter operating hours, where maintenance is typically conducted during shutdown periods.
Hello, it's important not to underestimate the value of conducting thorough walkarounds. Often, tasks that may seem unproductive actually yield more benefits than initially thought. The key lies in the way these tasks are performed. As a former CM tech who frequently conducted walkarounds, I discovered issues that operators or production personnel may have overlooked. This could be due to a lack of understanding, a reluctance to address problems, or simply not caring. In addition to identifying these issues, taking a wider perspective proved to be beneficial, as it allowed me to connect the dots between various aspects of maintenance. As an advocate for TPM, I recommend incorporating visual controls to streamline inspection processes. By utilizing visual aids such as marked gauges, temperature-sensitive tape, transparent guards, and oil level indicators, you can optimize your walkaround route, especially in a large facility. If you're new to TPM methods for autonomous inspection, I encourage you to seek out resources to enhance your understanding. Best of luck on your maintenance journey. Regards, Mike.
When it comes to manufacturing facilities, it is common to experience downtime for set-up changes and retooling, which are essential for product or production-related processes. By aligning preventive maintenance (PM) work with these downtimes, facilities can effectively schedule and prioritize maintenance tasks. Additionally, recording downtime caused by breakdowns can help justify the need for PM work to prevent future breakdowns. If equipment failures are primarily a result of wear, fatigue, or corrosion, implementing PM strategies is essential. However, if breakdowns are often classified as 'no fault found,' it may be challenging to justify PM activities. Ultimately, it is important to consider overall downtime, including both PM and breakdown maintenance (BM), to ensure efficient and effective maintenance practices.
When determining the best maintenance program for your facility, it is important to align it with your company's business goals. A successful program should target specific equipment needs based on factors such as criticality to the operation. Implementing a Predictive Maintenance (PM) program utilizing Reliability Centered Maintenance (RCM) principles can help to ensure that your equipment is properly maintained to prevent failures. The key to a successful PM program lies in targeting equipment that requires attention, specific tasks to predict, prevent, or detect equipment conditions, and ways to correct failure modes. Using handheld technology to gather data and monitor the effectiveness of the program is essential for success. Regularly reviewing and adjusting the PM program, known as Dynamic PMs, based on equipment performance metrics like Mean Time Between Failure (MTBF) and Mean Time Between Repairs (MTBR) is crucial. This helps in extending the life of equipment and identifying areas for improvement. Ultimately, the goal is to capture work history for each piece of equipment and ensure that maintenance tasks are being carried out effectively by all trades involved. By focusing on these key elements and actively implementing the plan, you can ensure that your maintenance program is not just a paperwork exercise but a proactive strategy for equipment reliability.
James, it seems like you may be focusing on the wrong aspect of the inquiry. The main discussion is on effectively handling a PM program in a non-stop 24/7 environment, rather than just the components of a solid PM program, in which your response does align well.
Your proactive approach towards prevention maintenance is commendable. In a 24/7 production schedule, comprehensive inspections can certainly be a challenge, but they are vital for ensuring smooth operations. One method you might consider is to incorporate a rotating downtime system, where individual production lines are halted for thorough PM at different times. Taking one line down for a short time shouldn't significantly impact overall output, but it provides technicians with the access they need. Techniques like thermographic inspection and vibration analysis, which can be performed while machines are running, can also be beneficial. Also, don’t underestimate the power of an effective Computerized Maintenance Management System (CMMS) to keep all your maintenance and inspection records organized and easy to access. This will provide vital visibility to the overall health of your production system and help identify patterns and optimize maintenance activities.
