APPLICATION OF ANTI-FRICTION COMPOSITE MATERIALS FOR INCREASING THE DURABILITY AND TRIBOTECHNICAL PROPERTIES OF HYDRAULIC EQUIPMENT UNITS

Abstract

In conditions of limited financial and material resources, the problem of technical rearmament of agricultural production cannot be solved only by increasing the supply of new equipment. A significant role in this process is assigned to the reasonable use of the available fleet of machines, maintenance of its technical level with the help of qualified maintenance. The power hydraulic cylinder occupies a special place here. The experience of operating hydraulic machines has shown that the share of hydraulic cylinders accounts for 17...30% of failures of the entire hydraulic system. Some agricultural enterprises are forced to carry out repairs on their own. At the same time, due to the lack of experience, technology and equipment, the resource of repaired units often does not exceed 30–60% of new resources. Therefore, the development and implementation of a new repair technology, based on the use of polymer parts made of antifriction composites based on supramolecular polyethylene, abbreviated SVMPE, in the tribo connections of power hydraulic cylinders, will allow to reduce the cost and repair time, which is of significant importance.
