Non-destructive methods and improvement of the cooling tower operation reliability, as an aspect of renewable energy sources thematization
Апстракт
Cooling towers use significant amounts of water, and the cooling system is often the most efficient energy user in a building during the cooling season. Maximizing the energy efficiency of the cooling system can be significantly improved by optimising the cleanliness of the tower heat transfer surfaces and the heat transfer surfaces of the heat exchanger cooling system. Cooling towers belong to the group of contact heat exchangers, and they are an integral part of almost every process plant, which failure can produce long-term downtime and significant material losses. Bearing in mind this fact, it is necessary to check electric motor, the fan and its components in a reliable way in order to ensure the required continuity of the process in the appropriate period of time. Previously methods of checking fan parts in accordance with the manufacturer's manuals included only visual inspection of the fan blades and checking the tightening torque of the blades for their holders. The mentioned ...methods have proven ineffective and insufficient from the point of view of maintenance of process plants during working life, which has led to the fan's failure and the blade holder's breakage at the point of connection with the blade. Hence, for the needs of appropriate maintenance, new methods for assessing the condition of fan blade holders have been established, which include the application of conventional non-destructive methods for the assessment of surface and volumetric defects of blade holders. The mentioned method of checking the blade holders has presented in detail in this paper.
