PREVENTIVE MAINTENANCE VS PREDICTIVE MAINTENANCE
The goal of any maintenance program is to keep equipment operating as long as feasible and without issues. Nonetheless, there are other kinds of maintenance plans that approach the procedure in different ways. Predictive maintenance and preventative maintenance are two of the most popular.
Predictive and preventive maintenance have different scheduling requirements, although they are both planned ahead of time. Whereas preventive maintenance is scheduled according to a set time period, predictive maintenance is performed according to the state of the equipment.
What is predictive maintenance?
Predictive maintenance, a type of condition-based maintenance that is carried out only when machinery deviates from predetermined performance standards, is a subset of the Industrial Internet of Things (IIoT). Machine performance is measured, tracked, and aberrant performance is alerted to operators through condition monitoring.
Predicting the remaining service life allows for the scheduling of maintenance in advance once performance parameters are outside of an acceptable range. This maximizes equipment uptime and lowers labor expenses by delaying maintenance until it is absolutely necessary.
Digitalization is necessary for predictive maintenance to work. With condition monitoring, an abundance of data is gathered, but without a useful method to view that data, it is all but worthless.
Predictive maintenance costs more up front than other maintenance techniques since it requires digitization and associated workforce training. This may put off smaller businesses or those with tighter finances, but predictive maintenance may save a lot of money over time
What is preventive maintenance?
Preventive maintenance is a type of routine maintenance that is planned on a regular basis, much as an annual physical or routine oil change for an automobile. Preventive maintenance schedules are strictly time-based, but the interval of time selected is determined by the estimated service life of the part in order to reduce the likelihood of an early failure.
Preventive maintenance has higher labor costs than other types of maintenance since it is carried out whether or not it is absolutely required to keep a machine operating. However, because there is no requirement for in-depth training or a financial investment in digital technology, the initial expenses are cheaper.
Important distinctions between preventative and predictive maintenance
Predictive and preventative maintenance differ in a few key ways that will help you decide which is appropriate for your scenario. The scheduling of maintenance is, of course, the primary distinction. Predictive maintenance, as previously indicated, is scheduled on machine condition, but preventative maintenance is not.
Preventive maintenance is routinely carried out, thus it is easy to estimate the related expenditures ahead of time. However, because maintenance is done more frequently, these expenses are higher. Because preventive maintenance is carried out before a machine starts to operate outside of allowable performance limitations, it is also intrinsically less dangerous than predictive maintenance.
Because they depend on machine performance and have variable intervals, predictive maintenance costs are difficult to anticipate. Nevertheless, compared to preventative maintenance, this implies maintenance is only done when necessary, lowering overall maintenance expenses.
Because predictive maintenance operates machinery significantly closer to the point of failure, there is a larger risk involved. But when predictive maintenance works, it pays dividends. It increases working hours while reducing maintenance expenses and resource usage.
Recap
Although they are similar, predictive and preventative maintenance differ in important ways that must be understood in order to make the best decision. A summary of these variations is given below.
Predictive Maintenance
- No predetermined timetable
- Lower long-term costs but higher upfront costs
- elevated risk
- maximizes the amount of time between maintenance tasks
Preventive Maintenance
- Regularly planned
- More long-term costs, but lower starting costs
- Low danger
- Whether maintenance is necessary for continued functioning or not, it is still carried out.
