Predictive Maintenance: What it is, how it works and the benefits of implementing it.
In the industrial field, installations and machinery represent the core of any production process, and their optimum performance is essential. Despite their importance, machines are not exempt from showing signs of wear and tear or experiencing unforeseen failures.
In the current era of Industry 4.0, characterized by its dynamism and competitiveness, it is essential to have a constant and efficient production, minimizing interruptions as much as possible.
Predictive maintenance emerges as a response to this need, offering a variety of innovative solutions that not only seek to maximize productivity, but also to prevent unforeseen costs.
The flexibility and adaptability of this technique has driven a growing corporate culture focused on implementing constant monitoring to assess and preserve the health of machinery.
From DSP we would like to invite you to learn about the benefits and the different predictive maintenance techniques that can prevent failures in your machinery.
What is predictive maintenance?
Predictive maintenance is characterized by the use of advanced tools and techniques for constant monitoring and data analysis to identify anomalies in the operation and possible defects in equipment, machinery and processes. Its main objective is to address these irregularities before they materialize into failures.
In general terms, the predictive maintenance process is developed as follows:
- It uses sensors and machine data to track machine status in real time.
- Analyze these data for anomalies, deviations or deteriorations.
- Based on this information, it uses models and algorithms to forecast future downtime or maintenance needs.
This approach allows maintenance to be carried out in a targeted and timely manner, thus minimizing unplanned downtime and reducing associated costs.
Predictive maintenance supports various types of machinery and equipment and is supported by cutting-edge technology including the Internet of Things (IoT), machine learning and advanced analytics.
As a result, companies experience increased plant availability, an extension in the service life of their machinery and a significant improvement in operational efficiency.
What is the purpose of predictive maintenance?
The fundamental purpose of predictive maintenance is to anticipate and prevent potential failures or problems inindustrial machinery and equipment before they occur.
Through the application of advanced technologies, such as constant monitoring and data analysis, this technique seeks to identify anomalies, deviations or deteriorations in machine operation.
Predictive maintenance has the potential to reduce machine downtime by 30% to 50% and increase machine life in the range of 20% to 40%, according to consulting firm McKinsey & Company.
Key objectives of predictive maintenance include:
- Avoiding unplanned stops
- Improve machinery reliability
- Eliminate the need for corrective maintenance
- Maximize machine uptime
- Improve the service life of machines and equipment
- Preventing equipment repairs or disassemblies
- Identify potential failures that could disrupt production
A successful and continuous implementation of the predictive maintenance strategy significantly reduces the probability of interventions that may affect productivity.
Predictive maintenance techniques
There are several techniques associated with predictive maintenance, we explain some of them:
Vibration analysis
It is a technique used to evaluate the condition of machinery and equipment by detecting and interpreting the mechanical vibrations they generate. By monitoring vibrations, possible faults, imbalances or defects in the machines can be identified.
Ultrasound
The ultrasound technique consists of the use of high frequency sound waves to detect and analyze imperfections or irregularities in various materials, being especially useful in the identification of non-visible faults, such as leaks in machinery or structures.
Thermography
Thermography is a technique that uses thermal imaging to visualize and analyze temperature variations on surfaces. This tool reveals heat patterns, allowing the detection of anomalies and the identification of potential problems in electrical, mechanical or structural systems.
Oil Analysis
Oil analysis is a technique that involves the detailed evaluation of lubricant samples to obtain crucial information about the condition and performance of machinery. This process allows the identification of possible wear, contaminants or problems in the components.
Videoscopy
It is a visual inspection technique that uses cameras and specialized equipment to visualize inaccessible or hard-to-reach areas. This tool allows detailed evaluation of internal components, facilitating the detection of possible defects or damage to machinery, piping or other systems, without the need for disassembly.
Shaft alignment
It is a crucial procedure in industrial machinery that seeks to correctly adjust and position the shafts of two components to ensure efficient operation. This process helps prevent premature wear, reduces vibrations and optimizes machinery performance.
Which sectors can benefit from implementing predictive maintenance?
Predictive maintenance is revealed as a concept perfectly aligned with the principles of Industry 4.0, characterized by the integration of advanced technologies in industrial processes.
In an environment marked by intense competition and high demands, establishing a constant operational flow in the industry becomes a determining factor for business survival and success.
By anticipating and addressing potential failures before they occur, companies can ensure the continuity of their operations, thus offering greater reliability to their customers and consolidating their position in a dynamic and competitive market.
Predictive maintenance finds application in various industries and fields. Our service extends to companies in the solar thermal, biomass, hydraulic, cogeneration, photovoltaic, aeronautical, mining, cement, automotive, paper, food, among others.
