ANALYSIS OF ABRASION DURABILITY OF GLAND SEALS IN HYDRAULIC EQUIPMENT FOR QUARRY EXCAVATION

Аннотация

Effective operation of crankcase hydraulic excavators in a hydraulic system is significantly affected by temperature conditions. In the hydraulic system, a sharp increase in the temperature of the working fluid or of the parts on which the packing gaskets are applied leads to burning of the packing gaskets, resulting in a loss of their elasticity and an increase in their hardness. Keywords. hydraulic systems, technical and technological solutions with high performance, hydraulic excavators, RH-40E. The practice of use of quarry hydraulic excavators in the world shows that the existing hydraulic system of excavators is considered to have a number of significant shortcomings, depending on the nature of operation. As the degree of contamination of hydraulic working fluids increases and their operational life decreases, scientific research is being conducted on intensive absorption of abrasive by hydraulic system parts. Malfunctions of parts of the hydraulic system of the quarry hydraulic excavator are divided into the following groups:  faults of high-pressure hoses, pipes and fittings (fittings) in their connecting part;  breach of tightness in the system (glands, seals);  hydraulic pump malfunctions;  hydraulic motor failures;  failures in hydraulic drives;  failures of control equipment; Выпуск журнала №-26 Часть–5_ Май –2025 147 MODERN EDUCATION AND DEVELOPMENT  failures of hydraulic cylinders.
