The impact of the amount of pollution of the fluid in the hydraulic system on the working resource of the quarry excavator

The the mining enterprises of the Republic of Uzbekistan pay great attention to improving the quality of operation of the main excavation and loading equipment, including reliability and durability of components and assemblies. The deepening of quarries in the mining processes leads to an expansion of the requirements for the efficient operation of hydraulic excavators and the reliable use of their power during excavation work in extremely difficult conditions. Modern hydraulic excavators are expensive technological equipment due to the high precision of manufacturing parts and require high-quality technical culture during their maintenance during operation. The operation of the excavator depends on a complex hydraulic system, the degree of malfunction of which reaches high levels today and becomes one of the main problems. Therefore, issues related to reducing the cost of operation of hydraulic systems of quarry excavators, increasing their reliability, are relevant.
