На основі удосконалення гідравлічної системи шляхом встановлення додаткового навісного обладнання – знижена забрудненість гідравлічної системи в процесі експлуатації екскаватора. Це дало змогу знизити робочі температури трансмісійної і гідравлічної системи. Таким чином розроблено і розраховано спосіб встановленого додаткового обладнання що підвищує продуктивність екскаватора. Крім того, зменшуються витрати на технічне обслуговування і ремонт. |

The use of hydraulic excavators in mining is the adoption of a technological process. The creation of new designs and
improvement of existing designs of mining equipment are needed to increase their productivity, durability, and operability. An
analysis of research and publications of scientific articles showed that the topic for our research is relevant and important, not
only for our country. Thus, scientists from Iran, Great Britain, China, India, and Belgium are researching ways and means of
reducing contamination of hydraulic systems in order to increase the productivity, durability, and performance of excavators.
However, such proposals from scientists as: installing total control over the quality of hydraulic fluids, changing the design of
the excavator, measuring the wear of parts of the hydraulic system, etc. – are not always acceptable in practice.
For example, the installation of total control over the quality of hydraulic fluids entails the need for large investments in
the development and creation of such control systems; to change the design of an excavator, not only design development and
full-scale testing are required, but all such improvements are not possible at enterprises that operate excavators.
The purpose of the article is to improve the hydraulic system of the machine by installing additional equipment. Such
equipment is designed to reduce the level of contamination of hydraulic fluid. There is no need for huge capital expenditures.
This additional equipment was installed on the CAT 349D2. Studies of the thermal load on the excavator drive have been
carried out. Research has shown the feasibility and reliability of installing additional equipment. Reducing the operating temperatures
of the drive hydraulic fluid increases the productivity, durability, and operability of excavators.
A real reduction in the cost of maintenance and repairs of the drive allows you to reduce the cost of soil development and
increases the competitiveness of the operating machine compared to new expensive machines. |
