Study on Design of Working Device and Hydraulic System of Hydraulic Excavator Based on Computer Aided Technology

Abstract

This paper expounds the importance of hydraulic excavators in urbanization and infrastructure construction, and reviews the history of the emergence and development of hydraulic excavators.Based on the computer aided technology and the working process of the hydraulic system in the practical application, the paper expounds the principles to be followed in the design, so as to realize the design and research of the working device and the hydraulic system of the excavator.

Improving the efficiency of diesel filters to reduce the adverse impact of fuel on the environment

“…The filtration process in the purification systems is generally considered to be a process occurring at � � 𝑐𝑐���𝑡𝑡, and the life is the time of operation from the initial to the final pressure drop on the filter element, due to the quality of the porous material and the design of the filter element. [5] The operating life of the і-th stage of cleaning can be presented in the form of:…”
