Title of the thesis:The economic loss reduction in the process of monitoring of compressed air leakage
Summary:Energy resource management is one of the key issues to address today's efficiency in manufacturing plants. The energy produced by the compressed air seems to be efficient and inexpensive because the air is considered to be unlimited medium. However, compressed air is the most expensive secondary energy source, which is why it is necessary to pay high attention to its economical control. The main objective of this work was to evaluate the measured compressed air leaks and to prepare precautions to prevent these energy losses. In a particular company, leaks were measured on 21 production lines in the form of 2,370 m3 of leaking air per day. Subsequently, these losses were recorded in the maintenance control system and the maximum possible part of these abnormalities was removed. Releases have been financially assessed by calculating the price of compressed air. The performance, evidence and elimination of these abnormalities is the responsibility of the maintenance department, which is an indispensable part of manufacturing enterprises. Total Productive Maintenance (TPM), developed from Totally Productive Management, is a maintenance focusing on maximizing device efficiency, which includes not only eliminating downtime, but also continually improving fault-free operation. The reduction of economic losses does not only mean the removal of measured leaks by maintenance personnel, but mainly the creation of leak prevention. The essence of this work was the creation of a set of recommendations to reduce these losses, including the establishment of a regular check for compressed air leaks, the selection of new equipment based on the calculation of the payback period and the theoretical design of a continuous measurement of the flow volume of compressed air in the distribution. All recommendations are aimed towards more efficient management of energy resources, i.e. the adoption of energy management principles and the acceptance of this issue across the enterprise.
Key words:compressed air leaks, maintenance, TPM, return of investment, energy management
