Preventive maintenance is a proactive maintenance strategy where the physical assets of an organization are checked on a routine basis to reduce their chances of failure, which can lead to unplanned downtime. An effective preventive maintenance program improves the reliability of the assets and enhances their overall performance.
Preventive maintenance relies mainly on equipment data, making technology a significant aspect of the entire process. Hence, it is important to invest in the best preventive maintenance software for the best results. Along with this, implementing an effective preventive maintenance strategy is important, as it ensures that equipment is regularly serviced and potential issues are identified before they lead to breakdowns.
What Is Preventive Maintenance?
Think of preventive maintenance as a regular health checkup that keeps track of important parameters, ensuring the body (asset) functions properly.
Preventive maintenance focuses on maintaining each piece of equipment and ensuring they consistently perform optimally. It is scheduled on the basis of usage or time, reducing the likelihood of failure and improving efficiency.
Through preventive maintenance, you improve the reliability of your equipment, which trickles down to better productivity and customer satisfaction.
Different Types of Preventive Maintenance
There are different types of preventive maintenance that organizations can conduct. Each type is triggered by a specific parameter. In the section below, we will look at them.
1. Time-Based Preventive Maintenance:
Preventive maintenance tasks are triggered after a set time, such as every month or every six months.
2. Usage-Based Preventive Maintenance:
Here, preventive maintenance tasks in a Preventive maintenance program are triggered based on meter readings. For example, maintenance tasks may be scheduled after every 5,000 hours of machinery operation.
3. Condition-Based Maintenance:
In condition-based maintenance, particular trends are identified that necessitate maintenance tasks. Such as, when equipment meets a temperature threshold, maintenance tasks are scheduled.
4. Predictive Maintenance:
In predictive maintenance, predictive analytics is used to predict a failure and act beforehand. For example, a forecast that a machinery failure may occur in the next two weeks triggers maintenance operations.
5. Prescriptive Maintenance:
Some vendors recommend how often predictive maintenance operations must be conducted.
How to Conduct Preventive Maintenance?
Below is a six-step framework that can help organizations conduct preventive maintenance tasks.
Step 1: Create an Inventory of Equipment
Without knowing what you have and what needs to be maintained, you can’t schedule maintenance tasks. You can divide the assets based on different facilities, and they should have a unique identifier, a brief description, and an operational context.
Step 2: Establish a Schedule
Now, you need to structure a scheduling system based on what your equipment needs. This reduces the need for reactive maintenance and builds accountability among the employees.
To streamline the scheduling of maintenance operations, you can take the help of an Enterprise Asset Management Tool (EAM) or a Computerized Maintenance Management Software (CMMS).
Step 3: Create Specific Task Lists
This is the most crucial step of the preventive maintenance program. Define the following for each asset you have added to your list.
- The predictive maintenance task that needs to be conducted. This could include tasks such as lubrication, inspection, cleaning, or replacement.
- State the interval at which these tasks will be performed. They can be on a daily, weekly, biweekly, or monthly basis.
- Create a clear work order that is easier for the technician to understand.
Investing in maintenance software allows the tool to automate these tasks. This minimizes manual work and reduces the chances of error.
Step 4: Centralize Equipment Manuals
Ensure that the vendor manual, part listings, drawings, and other information about the equipment are in a centralized location. This way, the maintenance team has easy access to all the essential information, and it improves the efficiency of the operations. It is best to document the information digitally so that it’s accessible from everywhere.
Step 5: Have an Inventory Management Plan in Place
You can’t conduct predictive maintenance unless you are stocked up on all the essential inventories. This includes the spare parts that are critical to the assets. Implement an inventory management plan that keeps essential filters, lubrication, belts, etc., readily available.
Step 6: Aim for Continuous Improvement
A good predictive maintenance strategy within a Preventive Maintenance Program is continuously evolving, changing, and adapting to the growing needs of the organization. Look at your failure data, technician feedback, and completed work orders to refine task frequencies and manage your assets better. Even if an asset fails after preventive maintenance, use the feedback to take corrective measures.
Role of Technology in Preventive Maintenance
Technology plays a significant role in preventive maintenance. It helps improve inefficient scheduling, monitoring, and execution of preventive maintenance operations by providing tools that facilitate better planning and resource allocation. With the help of maintenance software, organizations can use real-time analytics and automate work order management. This procedure reduces the risk of failure and improves the efficiency of the tasks.
In conclusion, with the help of intelligent sensors and sophisticated data, you will be able to conduct a preventive maintenance program with better precision.
