The point of preventive maintenance is to keep equipment breakdowns from happening. That’s why it’s important to conduct routine maintenance on parts and machinery with age-related failure patterns. Although there isn’t a universal standard on how many types of PM there are, most tasks fall into four specific categories.
Periodic maintenance, also known as time-based maintenance, is completed at scheduled intervals throughout the year. It can be accomplished weekly, monthly, quarterly, or even annually. The best way to determine how often you should perform time-based maintenance is to check the manufacturer’s guidelines. Equipment comes with specific care recommendations to prolong the life of the equipment.
Also known as performance-based maintenance, this PM type is achieved when a meter reading shows that specific machinery should be attended to. Common measurement variables include the number of hours the machine has been running, operating conditions (e.g., pressure and flow rate), and more.
This method monitors how well certain machinery is doing based on sensor devices. Once a sensor detects a problem, a work order is automatically created and given to a maintenance worker.
Prescriptive maintenance is based on data gathering with machine learning software. For instance, software evaluates equipment conditions over time, measures operational risks, and makes recommendations for improvement.
