Do you know what maintenance is? Maintenance can be interpreted as a series of forms of activities or work carried out to return an equipment to a condition where it can carry out functions as specified. The need for maintenance is done to avoid failure in a system. Ideally, maintenance is carried out to maintain the components / equipment so that they can run according to their initial functions. The process considers many aspects of management, one of which is eam or enterprise asset management as a modern management pattern. Every company that wants to develop amidst fierce competition in the modern era must consider maintenance as a key to success.
To note, maintenance is the main key to maintaining the reliability and security of a system, especially for vital systems. Failures caused by minor components on the system can disrupt and even stop all activities from the system work. In electrical transmission systems, transformers are a vital component that requires proper maintenance to maintain and guarantee continuity in the distribution of electric power systems, increase reliability, availability and efficiency, extend equipment life, reduce the risk of failure or equipment damage, increase safety equipment and reduce the length of time outages due to interference.
Time Based Maintenance or better known as periodic-based maintenance is a common approach used in maintaining equipment. Maintenance is carried out regularly determined based on an analysis of the occurrence of damage / failure in a period of time (for example, doing maintenance with a period / interval). Or in other words, age (time of use of equipment) is estimated based on the data of the time of occurrence of damage / failure on the equipment. Characteristics of equipment failures can be guessed by taking assumptions that are based on the risk or degree of tendency for failure to occur or better known as bathtub curves.
The TBM technique approach assumes that in the initial phase, the equipment failure rate is very high; this is more due to poor system design, poor system installation or improper use of equipment. When this problem appears and slowly corrects, the level of damage will decrease and will be close to a stable value. When entering the stable phase, the rate of damage will start constant. After approaching the end of the usage period, the level of damage will increase. TBM is implemented to prevent sudden damage and to maintain the optimum performance of the equipment according to the technical age. The technical age is the first consideration in this maintenance type.
Condition-based maintenance, also known as predictive maintenance, is a popular maintenance program developed late this decade. Maintenance is carried out by monitoring (monitoring) the system by taking measurements that detect the degradation of the system performance (lower function state), making it possible to control or eliminate the cause of failure before a larger system failure occurs. The CBM program recommends treatment actions (decision making) and the use of condition based maintenance tools based on information collected through a condition monitoring process. In CBM, the lifetime (age) of the equipment is monitored from its operating conditions measured by monitoring parameters such as: thermal temperature, temperature and humidity of the environment, loading. So that indications of failure can be seen from certain signs or changes in abnormal conditions.
The two types of maintenance above are very necessary in modern manufacturing processes. Its use is based on real needs and conditions that are being faced. Hopefully by reading this article you can add to your knowledge of modern manufacturing processes.
