The Importance of Technical Diagnostics for Ensuring the Reliability of Industrial Systems

The success and sustainability of the business industrial system is largely determined by the degree of effectiveness of the production system as its basic integral part. The reliability of the technical system, i.e., the probability of performing the projected goal function in the observed time period, along with the readiness and functional convenience is a basic indicator of the effectiveness of the production system. Maintenance, as an integral part of the production system, has the function of providing the projected level of optimal reliability by implementing activities aimed at ensuring the required level of technical readiness of parts of the technical system. One of the ways to ensure the optimal level of reliability of the technical system is the application of maintenance concepts according to the condition that allows monitoring and control of technical parameters of the state of the elements of technical systems within the production processes. The basis of the application of the condition based maintenance is the introduction of procedures for monitoring and control of condition parameters using technical diagnostic methods. Knowing the current state of the parameters that determine the degree of success of the projected function of the goal of the technical system gives the possibility of timely response to the occurrence of malfunctions and avoid the entry of the system into failure. The paper presents a systematic provision of regular monitoring and control of condition parameters of parts of the technical system of paper machines, specifically vibration levels on high voltage motors, within the industrial system for production of toilet paper using technical diagnostic methods using portable vibration control devices. By timely response to the observed occurrence of increased vibration levels at a specific critical position with the application of technical diagnostic methods and complex maintenance intervention activities, it is possible to avoid unwanted failure, long-term unplanned production downtime and very high maintenance costs. Along with the description of the specific event and preventive action of the maintenance service, the possibility of connecting the observed working position with other critical positions provided with systems for continuous monitoring of operating parameters, specifically the vibration levels of bearings, is indicated. By constantly striving and finding ways to raise the overall level of reliability to a higher level, maintaining the production system plays a major role in providing conditions for continuous production, achieving planned results and profits and sustainability of production and business industrial system in the increasingly demanding world market.
