ПОВЫШЕНИЕ НАДЕЖНОСТИ ЦИЛИНДРОПОРШНЕВОЙ ГРУППЫ МАЛООБОРОТНЫХ ДВИГАТЕЛЕЙ С ПРИМЕНЕНИЕМ ДИАГРАММ ПАРЕТО

Abstract

The article analyzes the main methods of increasing the reliability of operation of the cylinder-piston group currently used for the repair of the main power plants of sea vessels by ship repair plants in Ukraine, as well as abroad in many countries of the world. Improving the reliability of the main power plant of a sea vessel currently deserves special attention, and the importance of solving these problems is confirmed by a number of state, industry and other programs and decrees highlighting promising areas, one of which is to ensure reliable operation of the main power plant of a sea vessel. No matter how long low-speed engines are used, they have to be properly maintained, repaired by trained and qualified personnel who is capable of diagnosing a broken parts of the mechanism. The reliability of the engine must be maintained constantly at all these stages since the safety of the navigation of the vessel depends on the quality of the repair work, which in turn is controlled by the international maritime organization (IMO). The durability of the engine depends on the choice of the material of the parts, the method of obtaining the blanks, adherence to the manufacturing technology of the parts, assembly of the assembly, the quality of fuel and oils, modern and high-quality service. The high level of quality maintenance and operation of the unit, in accordance with the standards and requirements of the manufacturer, affects the durability of the parts of the cylinder-piston group, which are in severe operating conditions, namely, high temperature, pressure, and the presence of a corrosive environment. Therefore, these parts must have a given wear resistance, heat resistance, and corrosion resistance. Keywords: defect, failure, durability, reliability, cylinder-piston group, low-speed engines, Pareto diagram, Isikawa diagram.
