ANALYSIS OF THE CYLINDER ROD MOTION STATE IN THE PROCESSES OF AIR BUBBLE FORMATION IN THE WORKING FLUID OF THE HYDRAULIC SYSTEM

Аннотация

Annotation. 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. This reduces the service life of these seals, besides causing leakage of working fluid in the hydraulic system.
