When managing industrial equipment, you may agree that the maintenance of your assets is vital for your business. This is especially true when that equipment\u2019s functionality can heavily impact your company\u2019s efficiency and overall productivity. Alongside this, you\u2019ll find that well-maintained machinery is highly cost-efficient as you won\u2019t have to worry about unnecessary repairs that could\u2019ve been prevented through thorough maintenance. Furthermore, well-maintained machinery will allow you to develop high-quality products that perform well. This is where understanding what condition monitoring is and how this is a critical aspect of predictive maintenance<\/a>, comes into play.<\/p>\n\n\n\n

That said, if you\u2019re reading this, you may be developing or hoping to improve your maintenance strategy by reading about preventive and predictive maintenance. Preventive maintenance can be referred to as maintenance that is routine<\/a>, planned, and scheduled. Therefore, it is done regularly at intervals. Meanwhile, predictive maintenance can be seen as more of a condition-based kind of maintenance. This means that it\u2019s more focused on performing maintenance activities and schedules when your software indicates that it is necessary.<\/p>\n\n\n\n

While you may simply choose between either type of maintenance, using both may also be worth considering. Overall, it really depends on what you need and how much you\u2019re willing to pay. As such, it\u2019s essential to know which one you need for a particular case scenario and exactly what they can do. With this in mind, here are the differences between preventive and predictive maintenance:<\/p>\n\n\n\n

What You\u2019ll Need to Perform the Maintenance<\/strong><\/h2>\n\n\n\n

The difference between the two will be the costs, software, and machine downtime involved in them. For one, preventive is known to have a low overall investment cost compared to predictive maintenance. This is because predictive, on top of personnel and checklists, requires a special kind of software and tools and sensors to detect any issues with your machinery.<\/p>\n\n\n\n

Next, when it comes to software, preventive is known to use maintenance software for managing and maintaining equipment. Meanwhile, predictive maintenance uses condition monitoring software to keep a live feed on how your machinery is doing. With that, if you\u2019re hoping to look for an example of maintenance software, you may want to consider one provided by 60Hertz<\/a> or other service providers.<\/p>\n\n\n\n

When Do You Need to Do the Maintenance<\/strong><\/h2>\n\n\n\n

Another main difference between preventive and predictive maintenance is how often they\u2019re done. For instance, as mentioned, prevention is done regularly, and it\u2019s scheduled and planned regardless of whether your machinery has any damage or not.<\/p>\n\n\n\n

On the other hand, predictive maintenance is only done when needed, as you\u2019ll only perform maintenance activities when your software dictates that one is due. More specifically, the software involved with predictive maintenance will tell you when there is a failure or issue.<\/p>\n\n\n\n

From here, you can either perform a maintenance activity immediately to address it or do so on the next scheduled maintenance activity. As such, you may actually use both preventive and predictive together.<\/p>\n\n\n\n

Advantages<\/strong><\/h2>\n\n\n\n

Another difference worth considering between these two types of maintenance is their advantages. You may take the following advantages as an example:<\/p>\n\n\n\n

Preventive<\/strong><\/p>\n\n\n\n

  1. It prolongs the machine’s lifespan as you regularly maintain them.<\/li>
  2. Increased employee and customer safety because you won\u2019t wait for any issues to arise.<\/li>
  3. It\u2019s efficient, especially when you have very skilled personnel.<\/li><\/ol>\n\n\n\n

    Predictive<\/strong><\/p>\n\n\n\n

    1. It immediately identifies issues, allowing them to be fixed before a machine failure happens.<\/li>
    2. You can just buy parts that need to be replaced and not those still working, making it cost-efficient and even time efficient.<\/li>
    3. You can discover more efficient maintenance practices using the data collection involved in predictive maintenance.<\/li><\/ol>\n\n\n\n

      Disadvantages<\/strong><\/h2>\n\n\n\n

      With that, it\u2019s also worth considering the following disadvantages of these types of maintenance:<\/p>\n\n\n\n

      Preventive<\/strong><\/p>\n\n\n\n

      1. You may replace a part or perform a repair when it\u2019s not yet needed, making it unnecessarily costly and time-consuming.<\/li>
      2. It also requires more investment and time to make sure that you perform maintenance regularly.<\/li>
      3. It requires more effort for inventory management for replacement parts.<\/li><\/ol>\n\n\n\n

        Predictive<\/strong><\/p>\n\n\n\n

        1. The investment costs are higher as you\u2019ll have to pay for extra equipment and software<\/a>.<\/li>
        2. It can get in the way of planned projects as it\u2019s focused on detecting and addressing issues only when they appear.<\/li>
        3. It can result in failing equipment which can consume more energy and time since this is focused on detecting and addressing issues instead of preventing them.<\/li><\/ol>\n\n\n\n

          Conclusion<\/strong><\/h2>\n\n\n\n

          Maintenance is a core part of preserving product quality, overall safety, productivity, and efficiency. As such, it\u2019s important to devise a maintenance management plan for your equipment to especially avoid paying for repairs that could have been avoided. With this in mind, in devising a maintenance management strategy, it\u2019s essential to know preventive and predictive maintenance.<\/p>\n\n\n\n

          However, it\u2019s worth noting that you may use both of these together for a more effective maintenance strategy. This is especially since predictive can identify issues that need to be addressed for the next scheduled maintenance. Therefore, it may not have to be a case of choosing between them but thoroughly understanding which is best used for a certain case scenario. That said, hopefully, the guide above has helped you gain a deeper understanding of the difference between preventive and predictive maintenance.<\/p>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
