Predicting equipment and machinery failures in advance allows businesses to proactively plan maintenance, ensuring that machinery operates smoothly and stably. So, what is predictive maintenance and what is the process for implementing it? Let’s explore these questions with INTECH Service in this article!
What is Predictive Maintenance?
Predictive Maintenance (PdM) is a well-known concept in manufacturing and operations. Instead of performing maintenance on a fixed schedule, predictive maintenance uses data and analysis to predict when equipment might fail and carries out maintenance before the failure occurs. Predictive maintenance helps manufacturers reduce preventive maintenance costs, limit unscheduled maintenance, decrease maintenance frequency, and minimize production risks.
Benefits of Predictive Maintenance
Minimizes Downtime: By detecting early signs of failure, predictive maintenance helps prevent unexpected issues, thus reducing system downtime.
Increases Equipment Lifespan: Timely maintenance helps extend the lifespan of equipment, reducing replacement and repair costs.
Optimizes Maintenance Costs: Instead of performing routine maintenance on all equipment, predictive maintenance focuses on equipment that requires attention, saving costs. By predicting and addressing issues before they occur, businesses can avoid costly and unexpected repairs.
Enhances Operational Efficiency: Predictive maintenance helps identify potential problems early and resolves them before they impact equipment performance. It also reduces product defects caused by faulty equipment, improving the quality of the final product.
Common Predictive Maintenance Methods
Vibration Analysis
This method measures and analyzes vibrations emitted from machinery to detect deviations from a standard vibration level. Abnormal changes in vibration can signal issues like imbalance, bearing failure, or shaft problems. It is considered one of the most accurate methods for predicting machine faults and is applied to electric motors, pumps, fans, and compressors.
Infrared Thermography
Infrared thermometers use infrared cameras to detect high temperatures in parts of equipment. Abnormal temperatures can indicate hotspots, overloads, or leaks. This method quickly detects electrical, mechanical, and thermal issues and is commonly used for electrical panels, electric motors, junction boxes, and piping systems.
Oil Quality Analysis
This method tests oil samples from equipment for abrasive particles, viscosity, acidity, and other components. Analysis of viscosity, water or metal presence, and acid/base numbers helps evaluate equipment condition. It is used for hydraulic systems, gearboxes, and bearings.
Acoustic Emission Analysis
This technique monitors the sound frequency of equipment to detect technical issues and locate their sources. Most machinery generates sound waves during operation. By using acoustic sensors, technicians can detect small cracks or faulty welds that are not visible to the naked eye. This method is particularly useful for detecting gas or liquid leaks in production lines.
Predictive Maintenance Process
The predictive maintenance process includes the following steps:
Step 1: Data Collection
Install sensors and monitoring devices on each piece of equipment to gather information about its condition. Collected data include parameters such as temperature, pressure, lubrication, noise, etc. This data is transmitted and stored on servers for analysis.
Step 2: Data Analysis
Use algorithms and techniques to analyze the collected data. Compare measured values with established warning thresholds to detect potential issues. The goal is to identify patterns and trends, detect abnormal signs, and predict when equipment might fail.
Step 3: Fault Prediction
Based on data analysis results, the system predicts when equipment might fail. These predictions are provided to operators or technicians for appropriate maintenance actions.
Step 4: Maintenance Planning
Develop a maintenance plan based on predicted failure times to optimize equipment repairs. Prioritize maintenance tasks based on the severity of potential issues. This plan may include scheduling repairs, preparing materials, and spare parts, perform maintenance according to the plan.
