Preventive Maintenance and Corrective Maintenance

Maintaining equipment is vital to a business’s success. It increases productivity, helps employees work at a higher level, and reduces costs by avoiding costly repairs and replacements.

However, maintenance is not always a top priority for many businesses. The problems that occur when an organization fails to maintain its equipment can be disastrous.

Preventative 운전연수 Maintenance

Preventive maintenance is the practice of scheduling routine tasks to ensure that equipment and machinery continue to function at optimal levels. It reduces downtime caused by repairs, improves asset lifespan and efficiency, and enhances workplace safety. A preventive maintenance program also helps businesses maintain a consistent quality of work and keeps costs down by reducing workers’ compensation claims, fines, and other expenses associated with regulatory compliance.

Creating an effective preventative maintenance strategy requires cataloging all the assets on site, gathering original equipment manufacturer (OEM) manuals and reviewing maintenance history to establish a baseline for required inspections. Teams can also use a time-based approach, wherein maintenance is triggered by a specified interval, such as every 10 days, or by usage-based monitoring, where a scheduled maintenance action is triggered after a specific benchmark, such as a certain number of miles or production cycles. 운전연수

While there is no perfect preventive maintenance strategy, the best approach starts with a review of manufacturer recommendations and the CMMS database to identify potential tasks. Then, the team can Goldilocks the schedule and determine a frequency that is just right to reduce maintenance costs and avoid unplanned downtime. The result is a business that operates at full capacity, minimizes risk of costly and time-consuming breakdowns, and is backed by a strong foundation for successful facility management.

Predictive Maintenance

As technology continues to advance in the manufacturing industry, companies adopt new processes to cut costs, increase efficiency and boost productivity. One of these revolutionary advancements, known as predictive maintenance, applies data analytics to improve expensive break/fix and scheduled maintenance service models.

In predictive maintenance, sensors and machine data are analyzed to predict when equipment will fail and take the right action to avoid costly outages. This can include a variety of techniques, such as monitoring temperature, vibration analysis and detecting electrical anomalies. It is also possible to calculate remaining useful life using probability and time-series models.

This process takes the guesswork out of when machines will need repairs, allowing for more efficient maintenance. For example, if a pump is running hot, it’s likely that the machine will eventually fail, resulting in production stopping for hours until the pump can be fixed or replaced. In this scenario, a predictive maintenance system would monitor the pump’s temperature, and when it reaches a set threshold, the team is alerted that the machine is in trouble and will need to be repaired or replaced soon.

A predictive maintenance program typically requires the use of a computerized maintenance management system (CMMS). This software captures and analyzes inspection, repair, and maintenance activities for cost containment, risk reduction, and improved operational efficiency. It can help reduce planned downtime and unscheduled failures, while maximizing equipment life and increasing revenue.

Corrective Maintenance

Corrective maintenance tasks, also known as breakdown or reactive maintenance, rectify faulty systems and equipment that have broken down. These tasks can be unscheduled, but often arise when condition-based monitoring reveals an operating anomaly or excessive wear that suggests imminent failure. Prompt action minimises repair costs and downtime.

During a preventive maintenance task, a technician might notice that a fan belt is worn down and needs replacing. They might then create a corrective work order to replace the fan belt before it breaks, reducing the chance that a bigger problem will occur later, such as an air conditioning unit failing to cool the building.

This type of corrective maintenance can help increase the lifespan of assets, especially when coupled with a good preventive maintenance program. The maintenance team can note corrective maintenance tasks that need to be done before they affect other components, extending the lifetime of each component and the entire machine.

A computerized maintenance management system (CMMS) can help track and manage the corrective maintenance process. By recording all work orders, faults and issues, a CMMS can ensure that maintenance teams can identify and prioritize the right corrective maintenance tasks to decrease equipment downtime, production delays and service interruptions. The system can also assist with resource planning by allowing technicians to see which items need to be repaired or replaced first, decreasing the time it takes to find and replace a spare part.

Repairs

The goal of maintenance is to keep facility equipment and machinery operating efficiently. This is possible by implementing routine and preventive maintenance programs, which are a lot more cost-effective than repairs. It also lowers liability risks and encourages operator confidence, which helps reduce the chance of expensive litigation.

Repairs, on the other hand, are restoration work done when an asset breaks down or fails to function properly. Repairs can be either predictive or corrective in nature, and the amount of resources required to restore an asset to its original condition will vary depending on what caused it to fail.

Reliability-centered maintenance (RCM) analyzes the various modes of failure for each piece of equipment, and then creates a customized maintenance plan based on those outcomes. The goal is to increase the reliability of each piece of equipment to ensure maximum availability and productivity.

It’s important to differentiate between preventive and routine maintenance and repairs because implementing a schedule of tasks too early or too late can generate problems. For example, if a predictive maintenance task is performed too soon, the machine may break down and require repairs at an unnecessarily inconvenient time. On the other hand, if a preventive maintenance task is not implemented at all, it may eventually fail or break down and require costly repairs.

Modern CMMS solutions make it easy for your team to manage on-demand work orders and a robust preventive maintenance program at the same time. Get in touch with a Hippo representative to learn more and schedule a demo.
