Preventive maintenance (PM)/ vorbeugende instandhaltung , sometimes known as preventative maintenance, is maintenance performed on an asset in advance to reduce the probability of failure, reduce unplanned downtime, and extend its useful life. In practice, this entails inspecting equipment on a regular basis for minor flaws and correcting them before they cause failure. Inspections, calibrations, lubrications, adjustments, cleaning, and part replacements are all examples of preventive maintenance operations. Workers document the state of an asset while they perform preventative maintenance so they know when future repair is required.
Preventive maintenance systems help asset owners avoid downtime by scheduling service orders and inspections in advance of equipment failure. In comparison to reactive maintenance, which occurs after equipment has already developed problems that need to be addressed, preventative maintenance extends the life of any piece of equipment or essential asset. Preventive maintenance plans are often designed and implemented by maintenance teams in any firm, and they help to lower maintenance costs in the same manner that preventive healthcare cuts long-term medical costs.
The Importance of PM with example
Consider what would happen if you put off getting an oil change until your car’s engine failed. If this happens again, you’ll have to pay for an emergency tow truck to take it to a shop where the engine may be repaired. That is, assuming no catastrophic harm occurs. Otherwise, you’ll have to find and install a rebuilt engine (which can cost thousands of dollars). In the meanwhile, you’ll need to locate another form of transportation.
Waiting for your engine to break down is clearly inconvenient, as well as expensive in terms of money and time. It would be far easier to try to prevent the breakdown from occurring in the first place. This logic also applies to the equipment and assets you use on a daily basis.
Checklist for Preventive Maintenance
Inspection, detection, correction, and protection are the four sorts of actions on any preventative maintenance checklist. Any potential emergent concerns are detected during inspection and remedied as soon as possible. Cleaning laundry lint filters to avoid fires and minimise energy waste is an example of prevention.
Time-based or usage-based tasks might be found on a preventative maintenance checklist. It’s typically more easier to undertake calendar-based inspections at hotels, for example, which avoids confusion and enhances uniformity. Without a time-based deadline, staff may not know where they are on a usage-based checklist and hence feel less urgency. Any vehicles or equipment with built-in usage tracking are significant exceptions.
Examples of Preventive Maintenance
Based on the types of preventive maintenance, the following are examples of preventive maintenance.
- Every six months, a work order for gutter cleaning is created (calendar-based).
- After every 5,000 miles driven by a fleet vehicle, a technician is assigned an oil change work order (runtime-based).
- A shaft vibrates beyond normal limits, according to an equipment sensor. The bearings are inspected and maybe replaced, and a work order is prepared (condition-based maintenance).
- An analyst determines that a machine will most likely fail after 1,000 hours of operation after reviewing real-time and historical maintenance data. After 950 hours of runtime, a work order is created to check a subassembly (predictive maintenance).
When Should Preventive Maintenance Be Used?
Preventive maintenance should be performed at a minimum on assets that are vital to production and whose ability to execute their job is critical. You can then broaden your strategy to cover non-critical equipment and facilities. The maintenance department’s activities can also be better organised by using a PM programme. Thinking through your maintenance operations in detail allows you to better estimate demand for maintenance resources and balance the workload. The establishment of standardised PM task lists will ensure that all staff do their tasks in a consistent manner. Using a preventative maintenance plan as a guide also keeps the team on track and ensures that maintenance is completed when it is required in vorbeugende Instandhaltung Beispiele.
What is CMMS Software, and how does it work?
In complex assets like hotels, preventive maintenance and PM programmes are practically difficult to carry out without software. While the acronym CMMS stands for ‘computerised maintenance management system,’ it has stuck in many industry, with CMMS software gaining in popularity in organisations ranging from flats to hotels and even factories.
Members of the maintenance planning team use software to gain a real-time perspective of asset health without having to perform all of the time-consuming procedures that would otherwise be required. A hotel engineer, for example, used to have to keep a complete journal of HVAC unit purchase dates and issues. Today, software takes care of everything for them; they simply insert each new unit into the system, and the programme then checks average health and sends out automated notifications.
