What are the benefits of using oil analysis for predictive maintenance?

Oil analysis is a key technique for condition monitoring, which is the process of assessing the health and performance of machinery and equipment. By regularly sampling and testing the oil used in lubrication, cooling, and hydraulic systems, you can detect and prevent potential failures, optimize maintenance schedules, and reduce costs. In this article, we will explore the benefits of using oil analysis for predictive maintenance, and how it can help you achieve more reliability, efficiency, and safety in your operations.

1 What is oil analysis?

Oil analysis is the practice of extracting and analyzing a small amount of oil from a machine or equipment, and comparing it to a baseline or standard. The oil sample can reveal various information about the condition of the machine, such as wear, contamination, degradation, and performance. Oil analysis can be performed on-site or in a laboratory, using different methods and instruments depending on the type and purpose of the test. Some of the common parameters measured by oil analysis are viscosity, acidity, water content, particle count, and metal content.

No doubt there are many benefits of using oil analysis for predictive maintenance. To measure the condition of oil aging, oil contamination and equipment wearing, usually the oil samples need to be sent to an oil lab to get the data for maintenance plan and decision making. This traditional way can work well, but usually takes days to week to complete, which sometimes can not well meet the efficiency demands. In this case, the maintenance planner can think of introducing some onsite oil analysis way to provide instant data for onsite decision-making. With the technology develops, there are many portable onsite oil analyzers available on market with portable size, compact and convenient for onsite use, instant measurement results etc.

2 Why is oil analysis important for condition monitoring?

Oil analysis is important for condition monitoring because it can help you identify and diagnose problems before they cause breakdowns, downtime, or accidents. Oil analysis can detect signs of abnormal wear, such as metal particles, that indicate friction, corrosion, or fatigue in the machine components. Oil analysis can also detect signs of contamination, such as water, dust, or fuel, that can affect the lubrication, cooling, or hydraulic functions of the machine. Oil analysis can also detect signs of degradation, such as oxidation, that can reduce the quality and performance of the oil. By monitoring these indicators, you can take corrective actions, such as replacing or cleaning the oil, repairing or replacing the damaged parts, or adjusting the operating conditions.

In addition, many companies are combining the results from multiple data collection sensors - vibration, oil, motor current, pressure, speed, temperature, power generated, efficiencies, etc. Information from different sources can give an operator priceless insight when faced with making tough decisions about bringing down machinery for maintenance or repair. Multiple indicators supporting a suspected fault can save thousands of dollars in maintenance costs and lost production.

3 How can oil analysis improve predictive maintenance?

Predictive maintenance is a proactive approach to maintenance that aims to optimize the timing and scope of interventions based on the actual condition of the machine, rather than on a fixed schedule or a reactive basis. Oil analysis can improve predictive maintenance by providing accurate and timely data on the condition of the machine and the oil, which can help you plan and prioritize your maintenance activities. By using oil analysis, you can avoid unnecessary or premature maintenance, such as changing the oil too frequently or too infrequently, which can waste resources and reduce efficiency. You can also avoid costly or catastrophic failures, such as seizing or overheating, which can damage the machine and pose safety risks. By using oil analysis, you can extend the life and performance of your machine and oil, and reduce your maintenance costs and downtime.

4 What are the best practices for oil analysis?

To get the most out of oil analysis, you need to follow some best practices that can ensure the quality and reliability of your data and results. Firstly, it is essential to choose the right sampling point, method, and frequency for your machine and oil type. The sampling point should be representative of the oil condition and accessible for safe and convenient sampling. The sampling method should be consistent and avoid contamination or air entrainment. The sampling frequency should be based on the criticality and variability of the machine and oil condition. Additionally, samples should be labeled with relevant information, such as date, time, location, machine, and oil type. The samples should also be stored in clean and sealed containers and transported to the testing facility as soon as possible. Furthermore, you need to select the appropriate tests and parameters for your analysis that are relevant to your machine and oil type, compatible with standards and specifications, and aligned with your objectives. Finally, it is important to interpret the results by comparing them to baseline or standard values, analyzing trends or anomalies, communicating them to stakeholders like operators or technicians, and triggering appropriate actions such as maintenance or repair.

5 What are the challenges and limitations of oil analysis?

Oil analysis is not a perfect or foolproof technique for condition monitoring, and it has some challenges and limitations that you need to be aware of. To perform oil analysis correctly, skilled and trained personnel, equipment, and procedures are required. Moreover, external factors such as temperature, pressure, humidity and vibration can affect the oil condition and the sampling and testing process. Oil analysis can also be time-consuming and costly due to the sampling and testing materials, equipment, and services. Additionally, it can be incomplete or insufficient as it cannot capture all aspects or causes of the machine or oil condition, and may miss some critical or hidden issues depending on sample size, quality, and representativeness.
