RELIABILITY ANALYSIS OF THE MAIN COMPONENTS OF HYDRAULIC SYSTEMS OF MINING MACHINES
Abstract
Analysis of conditions and operating modes of hydraulic systems of mining machines shows that hydraulic units operate under stressful conditions characterized by constantly changing operating pressure, temperature conditions, pressure build-up rate, occurrence of hydraulic shocks and cyclic loads. This increases the probability of failure of hydraulic system components and can lead to failures, causing loss of working fluid. These circumstances make the task of developing effective schemes for protecting the hydraulic system from the release of working fluid when destroying high-pressure hoses and the problem of environmental protection urgent.
